Description:FIELD OF THE INVENTION

[0001] The present invention relates to a grain distribution system for public welfare schemes designed for efficient, fair, and hygienic distribution of grains to eligible individuals by ensuring accurate user verification, proper grain handling, and transparent tracking of distribution activities and inventory status.

BACKGROUND OF THE INVENTION

[0002] Ensuring fair and accurate grain distribution under public welfare schemes is critical to addressing food security and preventing malpractices. Existing systems often lack transparency and fail to efficiently verify beneficiary identity, leading to fraudulent claims and misallocation of resources. Additionally, the quality and hygiene of grains are frequently compromised due to poor storage conditions. Misuse, pilferage, and loss of grains further hinder the effectiveness of such programs. Grain distribution under public welfare schemes faces several challenges, including identity fraud, misallocation, and logistical inefficiencies. Storage conditions often fail to meet hygiene standards, resulting in spoilage and contamination. Corruption and pilferage during transportation reduce the intended supply, while the absence of real-time tracking makes accountability difficult. Additionally, outdated record-keeping methods hinder planning, causing supply shortages or surplus wastage. Lack of predictive analytics prevents proactive distribution adjustments based on demand fluctuations, undermining the program’s overall effectiveness and fairness.

[0003] Traditionally, grain distribution under public welfare schemes has relied on manual processes, including paper records and physical verification of beneficiaries. Distribution centres often maintain handwritten logs of supplies received and distributed, and manual checks are used to verify eligibility. Physical inspection and storage methods are employed to maintain grain quality. This manual approach is highly susceptible to human error, fraud, and logistical challenges. Stock management and planning are often based on basic historical data without advanced analytical tools, hindering effective resource allocation and timely replenishment. These traditional methods lack the real-time monitoring, data integrity, and automated verification systems needed for efficient and equitable distribution.

[0004] US4708265A discloses a practical and simple system that automatically measures and dispenses grain and powder type food products, such as sugar and flour contained within a canister type holder. The system consists of a drawer compartmentalized into precisely measured divisions with the topside uncovered and the bottom side selectively covered or uncovered by a moveable slide that allows for the pulling out of the drawer without spillage. The drawer will stop at one of several preset measured positions. These positions are controlled by a spring-pressured arm. With the drawer in a selected position the contents of the outward division or divisions of the drawer are dispensed accurately and immediately by pushing inwardly the moveable slide covering the bottom side. When the drawer is pulled outward an attached trailing horizontal upper slide prevents any of the contents within the canister from filling the empty area behind the drawer when the drawer is pulled out.

[0005] CN217674630U discloses a side-wall-free distribution vertical silo self-discharging silo system which comprises a silo body, a control gate and a main grain discharging pipe, and the bottom of the silo body is connected with the main grain discharging pipe through the control gate. A branch grain distributing pipe and a redirection plate are further included, an upper opening of the branch grain distributing pipe is communicated with the side wall of the main grain outlet pipe, and the redirection plate is rotatably connected into the main grain outlet pipe and can be switched between opening and closing of the main grain outlet pipe; when the redirection plate rotates to open the main grain outlet pipe, the redirection plate closes the upper opening of the branch grain outlet pipe, and the grains fall onto a belt of the air cushion belt conveyor under the granary after flowing out of the main grain outlet pipe; when the direction changing plate rotates reversely to close the main grain outlet pipe, the grains flow out from the branch grain distributing pipes after being turned by the direction changing plate; and a control handle for controlling and connecting the redirection plate is arranged on the outer side of the main grain outlet pipe. The branch grain distributing pipe is additionally arranged below the grain outlet control gate at the bottom of the vertical silo, and the original discharging process does not need to be started in the mode that the movable belt conveyor is connected in a lap joint mode.

[0006] Conventionally, many systems have been developed to facilitate various aspects of food distribution and storage, however systems mentioned in prior art have limitations pertaining to real-time monitoring capabilities, making it difficult to detect and prevent pilferage. Additionally, the existing devices ail to provide end-to-end solutions addressing all critical aspects of fairness, verification, tracking, hygiene maintenance, and loss prevention.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that is capable of verifying user identity and entitlement before grain distribution, ensuring fair and accurate distribution of grains to eligible beneficiaries. Additionally, the device is capable of tracking and recording all grain distribution activities, and detecting and preventing misuse, pilferage, or loss of grains during storage and distribution.

[0024] The present invention relates to a grain distribution system for public welfare schemes developed for structured and hygienic distribution of grains under public welfare programs, ensuring rightful access through user verification, maintaining grain quality, and enabling clear oversight of inventory and distribution records.

[0025] Referring to Figure 1, an isometric view of a grain distribution system for public welfare schemes is illustrated, comprising of a centralized multi-chamber silo 101 having multiple distinct airtight chambers 102, each chamber 102 equipped with a selective release valve 103, a multi-opening conduit 104 connected to the release valves 103 of the chambers 102, a collection tray 105 provided beneath the chambers 102, a touch interactive display panel 106 and an integrated audio speaker 107 provided with the system, a tumbling drum 108 integrated with the conduit 104, equipped with a vibrating unit 109 and perforated holes 110, water spray jets 111 provided with the drum 108, a drying unit 112 integrated with the drum 108, a quality check module 113 downstream of the drying unit 112 comprising LED (Light Emitting Diode) lighting 114 and AI-based optical pattern recognition cameras 115, a dispensing tube 116 attached downstream of the drying unit 112 and integrated with a bag dispenser 117, a holding clamp 118 arranged around the tube 116 outlet.

[0026] The disclosed system herein comprises of a centralized multi-chamber silo 101 comprises multiple distinct airtight chambers 102, each designed to store a specific grain type, ensuring no cross-contamination. Each chamber 102 integrated with a selective release valve 103 and a dispensing controller to regulate grain dispensing based on user entitlement. Each chamber 102 is hermetically sealed, maintaining grain quality and preventing spoilage.

[0027] The microcontroller authenticates user access, processes entitlement data, and activates the appropriate valve 103 to release precise grain quantities. Each airtight chamber 102 operates as an independent, hermetically sealed unit within the silo 101, constructed with corrosion-resistant materials to store a specific grain type. The chambers 102 are sealed with gaskets and pressure locks to prevent air, moisture, or pest ingress, preserving grain quality. Each chamber 102 has an individual inlet for loading and a dedicated outlet connected to the selective release valve 103.

[0028] The selective release valve 103 herein operates as a precision gate unit attached to each chamber’s outlet. Upon receiving a signal from the dispensing controller, the valve 103 corresponding to the selected grain type activates. The selective valve 103 opens to a calibrated degree, allowing the exact quantity of grain to flow into a dispensing chute. The valve 103 employs a motorized actuator for smooth operation and seals tightly post-dispensing to maintain chamber 102 airtightness. Each valve 103 is uniquely assigned to a specific chamber 102, ensuring accurate grain selection.

[0029] The dispensing controller mentioned herein receives user requests specifying grain type and quantity, cross-referencing them against stored entitlement data. The controller then signals the appropriate selective release valve 103 to open, releasing the precise grain amount. The controller monitors dispensing in real-time, logging transactions for auditability. The controller ensures secure, accurate, and automated grain distribution while maintaining system integrity and compliance with regulatory standards.

[0030] A multi-opening conduit 104 connected to selective release valves 103 of the silo’s airtight chambers 102, facilitating gravity-assisted grain flow to a collection tray 105 positioned beneath the chambers 102. A user authentication module, incorporating a ration card scanning means (QR/NFC readers) and biometric verification means (fingerprint/iris scanners), is operatively linked to the dispensing controller. The module authenticates users by cross-referencing ration card data and biometric inputs against a centralized or local database, ensuring only eligible users access their entitled grain quantities.

[0031] The multi-opening conduit 104 herein operates as a networked channel unit connected to each chamber’s selective release valve 103. Upon valve 103 activation by the dispensing controller, the conduit 104 corresponding to the selected chamber 102 opens, allowing grains to flow downward via gravity. The conduit 104 is constructed from durable, non-corrosive materials, thereby ensures smooth, unobstructed grain passage to the collection tray 105 below. Each conduit 104 segment is aligned with a specific chamber 102 to prevent mixing of grain types.

[0032] The collection tray 105 functions as a receptacle positioned directly beneath the multi-opening conduit 104 to receive dispensed grains. The tray 105 is constructed from food-grade, durable material. Upon completion of dispensing, as signaled by the dispensing controller, the tray 105 stabilizes the grain load and signals the user authentication module to confirm delivery. The tray’s design includes a sloped surface to facilitate easy grain retrieval by users. The tray 105 is detachable for cleaning and maintenance, ensuring hygiene and compliance with food safety regulations.

[0033] The user authentication module mentioned herein operates by integrating ration card scanning and biometric verification to validate user eligibility. Users present their ration card to the QR/NFC reader and submit biometric data via fingerprint or iris scanners. The module processes these inputs, cross-referencing them with a centralized or local database containing entitlement records. Upon successful authentication, the module signals the dispensing controller to release the specified grain type and quantity. An inbuilt microcontroller logs each transaction for audit purposes, ensuring secure, accurate entitlement verification while preventing unauthorized access, in compliance with regulatory standards.

[0034] The ration card scanning means operates using QR code or NFC readers integrated into the user authentication module. Users present their ration card, embedded with a QR code or NFC chip, to the reader. The reader scans the card, extracting encoded data such as user ID and entitlement details. The scanned data is transmitted to the module, which cross-references it with the database to verify eligibility. Upon successful validation, the reader signals the dispensing controller to proceed with grain dispensing. The microcontroller logs the transaction, ensuring secure and accurate entitlement processing.

[0035] The biometric verification means operates using fingerprint or iris scanners integrated into the user authentication module. Users place their finger on the fingerprint scanner or align their eye with the iris scanner, which captures biometric data. The scanner processes the data, generating a unique biometric template, and transmits it to the module’s microcontroller. The microcontroller cross-references the template with stored biometric records in a centralized or local database to confirm user identity. Upon successful verification, the microcontroller authorizes the dispensing controller to release the entitled grain quantity, logging the transaction for regulatory compliance.

[0036] Upon receiving a verification signal from the user authentication module, the microcontroller activates for confirming user eligibility and entitlement. The microcontroller cross-checks monthly entitlement limits against stored data, then signals the selective release valve 103 to dispense the specified grain type and quantity. The microcontroller monitors inventory levels via chamber 102 sensors, updating records in real-time to reflect dispensed amounts. The microcontroller logs transaction details such as user ID, date, time, grain type, and quantity in a secure database for audit purposes. The microcontroller ensures accurate dispensing, prevents over-allocation, and maintains data integrity, adhering to regulatory and operational standards.

[0037] A touch-interactive display panel 106 and an integrated audio speaker 107 configured with the system to provide entitlement display, step-by-step guidance, and user confirmation options through touch or audio inputs, with the microcontroller dynamically generating a scannable QR code for seamless payment processing via an electronic system. The touch-interactive display panel 106 activates upon system initialization, presenting a user interface with entitlement details, including access rights and transaction data.

[0038] The display panel 106 displays step-by-step guidance for navigation, prompting users to select options via touch inputs. The panel 106 dynamically renders a microcontroller-generated QR code, scannable by external electronic devices for payment processing. Users interact by tapping designated areas to confirm actions, such as approving transactions or acknowledging instructions. The display panel 106 updates in real-time based on user inputs and system status, ensuring accurate visual feedback. The display panel 106 supports multi-touch gestures for intuitive navigation, maintaining responsiveness across operational conditions.

[0039] The touch interactive display panel 106 as mentioned herein is typically an (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding step-by-step guidance, and user confirmation options via touch or audio. The touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0040] The integrated audio speaker 107 activates upon system startup, delivering audible step-by-step guidance for user navigation and entitlement verification. The audio speaker 107 vocalizes instructions, such as prompts for touch input or payment confirmation, in clear, pre-recorded audio sequences. The speaker 107 announces QR code generation, guiding users to scan it with an electronic device for payment processing. The speaker 107 provides audible confirmations for user actions, such as transaction approvals, and alerts for errors or system status changes. The speaker 107 operates in sync with the display panel 106, ensuring consistent communication.

[0041] A tumbling drum 108 integrated with the conduit 104, is a cylindrical apparatus designed to agitate grains for cleaning while facilitating water drainage, preserving grain quality. The tumbling drum 108 comprises a rotating drum 108 with perforated holes 110 and an internal vibrating unit 109. The tumbling drum 108 operates by rotating continuously within the conduit 104. The grains enter the cylindrical drum 108 through an inlet. As the drum 108 rotates, driven by a motor, grains are tumbled and agitated, causing friction that dislodges dust, chaff, and impurities. The drum’s inner surface may include baffles or ridges to enhance tumbling action. The perforated holes 110 on the drum’s surface allow water and smaller debris to pass through while retaining grains. The rotation speed is calibrated to ensure thorough cleaning without damaging grains.

[0042] During drum 108 rotation, the vibrating unit 109 generates controlled oscillations that agitate grains inside the drum 108. The vibrating unit 109, transmits vibrations through the drum’s structure, causing grains to move vigorously. This enhances friction between grains, loosening adhered impurities like dirt or husk. The vibration frequency and amplitude are adjustable to suit grain type, ensuring minimal damage. The vibrating unit 109 operates synchronously with the drum 108, optimizing cleaning efficiency while preserving grain integrity for downstream processing.

[0043] The vibration unit herein is used for subjecting the vibrational sensation to move back and forth or from side to side very quickly leading to controlled and reproducible mechanical vibration. The vibration unit consists of an electric motor (preferably a direct current motor) and an eccentric weight attached to the shaft of the motor. Upon activation of the vibration unit by the microcontroller, the motor
provides the required power to rotate the shaft, resulting in a rotational
motion to the eccentric weight, thus causing a vibration to the grains inside the drum 108 for cleaning and drain water while preserving grain quality.

[0044] The perforated holes 110 herein function to facilitate water and debris drainage during grain cleaning. As the drum 108 rotates and the vibrating unit 109 agitates grains, water used in the cleaning process, along with fine impurities like dust and small particles, passes through these holes 110. The holes 110 are sized to allow passage of water and debris while retaining grains, ensuring no loss of product. The holes 110 are positioned uniformly for maintaining consistent drainage across the drum’s surface, thereby supports efficient cleaning, prevents clogging, and preserves grain quality for further processing or storage.

[0045] An IR (Infrared) sensor integrated with the tumbling drum 108, detects grain presence, controlling the entry gate’s closure and activating water spray jets 111 provided with the drum 108 for washing the grains. The IR sensor operates by emitting infrared light and detecting its reflection to identify grain presence. Upon detecting grains, the sensor sends a signal to the microcontroller, triggering the closure of the entry gate to prevent overfilling. The sensor continuously monitors grain levels during tumbling, ensuring optimal loading.

[0046] Upon detection of grains by the IR sensor, the microcontroller activates a water spray jets 111 for washing the grains. The jets 111 release pressurized water through strategically positioned nozzles, uniformly spraying grains during drum 108 rotation. The water dislodges impurities like dust and debris, which exit through perforated holes 110. The jets 111 operate at adjustable pressure to suit grain type, ensuring effective cleaning without damage.

[0047] Post successful washing of the grains, the microcontroller actuates a drying unit 112 integrated with the drum 108 to dry grains with controlled warm airflow to uniformly dry grains. In addition, moisture sensors integrated with the drum 108 monitor moisture levels, terminating drying when ideal levels are achieved. The drying unit 112 employs a controlled warm airflow, driven by a heater and fan, to circulate air evenly through the drum 108. As grains tumble, warm air passes through perforated holes 110 for removing moisture. The airflow temperature and speed are regulated to prevent overheating or grain damage.

[0048] The moisture sensors herein operate by measuring the moisture content of grains during drying. Utilizing capacitance, the sensors detect moisture levels in real-time as grains tumble. The data is transmitted to the microcontroller, which adjusts the drying unit’s warm airflow intensity or duration. When sensors detect that grains have reached the pre-set ideal moisture level, they signal the drying unit 112 to terminate operation, halting airflow. This precise monitoring prevents over-drying or under-drying, ensuring grains maintain optimal quality and are ready for storage or subsequent processing.

[0049] A quality check module 113 located downstream of the drying unit 112 comprises of color sensor and AI-based optical pattern recognition cameras 115, illuminated by LED lighting 114, scan grains for foreign particles and defects. The color sensor comprises of RGB (red green blue) /CMOS (Complementary Metal Oxide Semiconductor) color sensors. The sensors detect color and texture variations, while cameras 115 analyze patterns. Data is processed by a microcontroller, which identifies impurities or damaged grains. Upon detection, the microcontroller triggers an audio notification, alerting distributors and beneficiaries. Non-compliant grains are diverted for further inspection or removal, ensuring only high-quality grains proceed for distribution or storage.

[0050] The RGB /CMOS color sensors integrated into the quality check module 113, activate as grains pass through the inspection area. The sensors capture red, green, and blue light reflections from grains illuminated by LED lighting 114. The CMOS sensor converts light data into digital signals, analyzing color and texture variations to detect foreign particles or damaged grains. The data is sent to the microcontroller, which compares readings against predefined quality thresholds. If anomalies are detected, the microcontroller triggers an audio alert. The sensors operate continuously, ensuring real-time quality assessment and maintaining high standards for grain output.

[0051] The LED lighting 114 integrated into the quality check module 113, activates during grain inspection. The LEDs emit consistent, high-intensity light across the visible spectrum positioned to illuminate. This ensures uniform lighting 114 for RGB/CMOS sensors and AI cameras 115 to capture accurate color and pattern data. The LEDs operate in sync with the sensors and cameras 115, controlled by the microcontroller to adjust brightness as needed. This stable illumination highlights foreign particles and defects, enabling precise detection.

[0052] The LEDs lighting 114 remain active throughout the inspection process, ensuring reliable visibility and supporting consistent quality assessment of grains. The LED lighting 114 used herein is a two-lead semiconductor light source also known as p-n junction which produce the lighting 114 when constant voltage is supplied across the diode. When the voltage is supplied across the diode, the electrons recombine with the electrons hole in the diode which result in conversion of electron into photons which is another form of light.

[0053] The AI-based optical pattern recognition cameras 115 herein are part of the quality check module 113, activate as grains pass under LED lighting 114. The cameras 115 identify foreign particles, damaged grains, or irregularities by comparing images to a quality database. This data is sent to the microcontroller which processes results in real-time. The cameras 115 comprise of an image capturing arrangement including a set of lenses that captures multiple images and the captured images are stored within memory of the imaging unit in form of an optical data.

[0054] The cameras 115 also comprise of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines foreign particles and damaged grains.

[0055] Upon detection of foreign particles and damaged grains, the microcontroller triggers an audio notification to alert distributors and beneficiaries. The cameras 115 operate continuously, ensuring precise detection and enabling the microcontroller to divert non-compliant grains for further inspection or removal.

[0056] A dispensing tube 116 is positioned downstream of the drying unit 112, channels dried grains into bags for user collection. Upon user activation, the tube 116 receives grains from the drying unit 112 through a controlled valve 103. The tube’s internal design ensures a steady, uninterrupted flow of grains, preventing clogging or spillage. The dispensing tube 116 is integrated with a bag dispenser 117 to aligns with the selected cloth bag, allowing precise filling. The tube 116 operates in coordination with audio-visual prompts to guide users, ensuring seamless operation. A holding clamp 118, encircling the dispensing tube’s outlet, secures the bag, enabling efficient and spill-free grain dispensing into the user-selected bag.

[0057] The bag dispenser 117 herein automatically provides cloth bags upon user selection via a control interface. When activated, a motorized assembly retrieves a single cloth bag from a preloaded stack within the dispenser’s storage compartment. The bag is then positioned at the tube’s outlet for grain filling. If a user lacks a personal bag, the microcontroller triggers audio-visual prompts to guide bag selection. The dispenser 117 ensures consistent bag availability, releasing one bag per transaction. The dispenser 117 coordinates with an optical sensor integrated with the dispensing tube 116 to verify bag integrity before dispensing, ensuring reliable operation and user convenience.

[0058] Upon bag placement by the dispenser 117 or user, the holding clamp 118 activates during grain filling to secure the cloth bag in place. The clamp’s motorized arms close around the bag’s opening, gripping it firmly to prevent slippage or spillage. The clamp 118 adjusts its grip based on bag size, ensuring stability throughout the filling process. Once filling is complete, the clamp 118 releases the bag automatically, allowing user retrieval. The clamp 118 operates in sync with the dispenser 117, ensuring precise alignment and secure handling, thereby enhancing efficiency and minimizing grain loss during dispensing.

[0059] The optical sensor herein used for continuously monitors the cloth bag during dispensing. The sensor emits light to scan the bag’s surface for defects such as tears, holes, or improper alignment. The optical sensor herein is used to detect bag defects. The optical sensor works by using light to detect the presence of the defects. The optical sensor contains a light emitter and a light detector. On actuation the emitter emits a beam of light which travels through the air until it hits the bag.

[0060] Upon detecting any defect in the bag, the sensor triggers an immediate alert via audio-visual signals, notifying the user and halting the dispensing process to prevent grain loss. The sensor’s high-resolution imaging ensures accurate defect detection. Once a defect-free bag is confirmed, the sensor signals the microcontroller to proceed with filling, ensuring quality control and reliable operation of the dispensing.

[0061] A weight sensor is embedded in each chamber 102 to continuously measures the weight of stored grains. Upon grain loading or dispensing, the sensor records real-time weight data and transmits it to the microcontroller. The sensor is calibrated to detect minute weight changes and ensures accurate inventory tracking. The sensor operates by converting mechanical pressure from the grain’s weight into an electrical signal, which is processed to determine precise measurements. The sensor functions consistently throughout the day, updating weight data at regular intervals.

[0062] Upon detecting discrepancies indicative of potential theft or loss, the microcontroller automatically generates and transmits theft alerts to designated higher officials via a secure communication protocol. The microcontroller enhances security and accountability in grain storage and distribution by ensuring real-time monitoring, accurate discrepancy detection, and prompt notification, thereby safeguarding inventory integrity and facilitating swift response to irregularities.

[0063] Furthermore, the microcontroller is programmed to generate and transmit pre-distribution stock recommendations and automated notifications to distributors and beneficiaries, utilizing historical distribution data, absentee counts, and the number of registered beneficiaries. The microcontroller enhances operational efficiency by providing data-driven stock allocation suggestions and timely alerts, ensuring effective communication with stakeholders. The microcontroller optimizes inventory management and beneficiary outreach, facilitating seamless coordination and informed decision-making for grain distribution processes by analyzing past distribution patterns and absentee trends.

[0064] Moreover, the battery is associated with the system for powering up electrical and electronically operated components associated with the system and supplying a voltage to the components. The battery used herein is preferably a Lithium-ion battery which is a rechargeable unit that demands power supply after getting drained. The battery stores the electric current derived from an external source in the form of chemical energy, which when required by the electronic component of the system, derives the required power from the battery for proper functioning of the system.

[0065] The present invention operates most effectively in the following manner, wherein the device functions under the control of the microcontroller to ensure accurate, secure, and efficient grain dispensing. Upon initiation, the microcontroller interfaces with the user authentication module, which includes the ration card scanning means and the biometric verification means, to verify user identity and entitlement by cross-referencing the credentials with the centralized or local database. Once authenticated, the microcontroller retrieves the user's monthly entitlement data and displays it on the touch interactive display panel 106, while providing audio guidance through the integrated speaker 107. The microcontroller activates the selective release valve of the appropriate airtight chamber 102 to dispense the entitled quantity of a specific grain type via the multi-opening conduit 104, using gravity-assisted flow. Grains enter the tumbling drum 108 where the vibrating unit, water spray jets 111, and drying unit 112 operate sequentially under microcontroller control, based on inputs from the IR sensor and moisture sensors, to clean and dry the grains to ideal moisture levels. The microcontroller then routes the grains through the quality check module 113, which uses the RGB/CMOS color sensors and AI-based optical cameras 115 to detect contaminants. Post-verification, the grains pass into the dispensing tube 116, where the optical sensor and holding clamp 118 ensure proper bag placement. The microcontroller logs all transactions, updates inventory, and sends alerts or recommendations as necessary.

[0066] Although the field of the invention has been described herein with limited reference to specific embodiments, this description is not meant to be construed in a limiting sense.
