FIELD
The present disclosure generally relates to an automated electro-mechanical system and method for scanning and grading objects.
BACKGROUND
Determining quality of objects is a prime important factor so that the market price of objects can be decided. Hence grading of objects is the need of the day. Grading can be manually. However, manual inspection is labor intensive, time consuming process and provides in-accurate grading results because of manual intervention. In-accurate grading results in financial losses due to rejection of objects. Thus, determining appropriate quality is of at most importance.
Alternatively, conventional scanning grading machines are used for grading object. However, such conventional scanning and grading machines consume more scanning and grading time for grading plenty of objects. Also, handling of plenty of objects is a difficult task as for fast scanning, multiple scanning devices are required which causes difficulty in handling objects, as each scanning device can be positioned at different location. Use of multiple scanning device is a costly affair. Further processing of objects is slow as processor is inbuilt of scanning devices. Further, scanning devices of conventional machines are not optimally utilized due to limited feeding of objects that result in inefficiency of the machine.
There are some prior art documents referring to grading. The US patent no. 5547063A titled ‘Apparatus and method of sorting objects’ comprises of a sorting system for sorting packages at high speed to a large number of destinations. The sorting system provides a feeding mechanism for depositing flat packages in an upright position on a conveying system. The conveying system includes lower and upper conveyors for supporting the package. Data may be encoded on the items and a data scanner may be provided which is located adjacent to the path for reading the data as the item moves along the path. Pluralities of ejection modules are included along the length of the conveying system ejecting individual packages

along the conveying system. The system uses multiple feeding stations to feed the flat objects but the data scanner used may not be fast enough to achieve high speed scanning and sorting compared to the speed of feeding. So the use of multi-feeders and multi-ejecting plungers becomes ineffective to carry the high speed process.
The US patent no. 3955678 titled ‘Sorting system’ comprises of a control system provided for maximizing flow rate and sorting rate by minimizing the spacing between articles of varying length. The system measures the length of the articles and controls their movement into the sorting system so as to minimize spacing between the articles. The measuring device may not be fast enough to measure lengths of the articles rapidly for controlling their movement so as to increase the flow rate and sorting rate. Also the measuring device may not be able to process rapidly in case the articles are fed from multi-directions.
Hence, there is a need for a system and a method for scanning and grading objects that alleviate aforementioned drawbacks.

DETAILED DESCRIPTION
[0009] The present disclosure will now be described in detail with
reference to the accompanying drawings. Now, refer in more detail to the exemplary drawings for the purposes of illustrating non-limiting embodiments of the present disclosure. ‘Object’ refers to agricultural and/or non-agricultural products as per the need of the present disclosure.
FIG. 1 illustrates a system (100) for scanning and grading objects which scans and grades/categorizes multiple objects in less time, in accordance with one embodiment of the present disclosure.
The main non-limiting components of the system for grading and ejecting objects (100) as per Figures 1 and 4, in accordance with the first embodiment as illustrated in FIG. 1, are: at least one controller (10), at least one feeder (20), at least one transfer mechanism (30) at least one scanning unit (40), at least one programmable processor (50), at least one ejection mechanism (60), at least set of grade/category containers (70) and at least one return mechanism (80).
The feeder (20) is controlled by the controller (10). The feeder (20) is provided on upper portion of one end of the transfer mechanism (30) such that objects falling from feeder (20) are received on transfer mechanism (30). Moreover, the feeder (20) singulates objects and continuously releases a set of objects on the transfer mechanism (30) such that set of objects fall in series. The feeder (20) is parallel to the transfer mechanism (30). The feeder (20) feeds singulated objects manually and/or automatically.
The transfer mechanism (30) has a plurality of set of examination beds (31a to 31d). Each set of examination beds (31a to 31d) relocates on the transfer mechanism (30) in series. Also, distance between adjacently disposed sets of examination beds (31a to 31d) is predetermined. Number of examination beds in one set of examination beds (31a to 31d) is equal to number of objects released in one shot of the feeder (20) such that one examination bed (31a to 31d) is fed with one object without any miss from the feeder (20). The transfer mechanism (30) relocate each set of examination beds (31a

to 31d) with objects away from said feeder (20) upto the ejection mechanism (60) upon direction of the controller (10).
The scanning unit (40) is provided between the feeder (20) and the ejection mechanism (60) and positioned above or in vicinity of the transfer mechanism (30) such that each object of each set of examination beds (31a to 31d) relocating from the feeder (20) on the transfer mechanism (30) is scanned by the scanning unit (40) upon direction of said controller (10). The scanning unit (40) scans one or more of at least one internal parameter(s) and at least one external parameter(s). In one embodiment, the scanning unit (40) includes two or more scanning devices (not illustrated in Figures).
In one embodiment, the scanning unit (40) is a high speed scanning unit. The high speed scanning unit (40) includes an advanced programmable cameras which can be “synchronous”, “asynchronous”, “regular”, “color” or “multi-spectral” cameras, advanced X-ray cameras, advanced spectrometer. Also, multiple spectral light sources, multiple adjustable mirrors/ prisms, an advanced backlighting system or any other type of supporting system for efficient scanning can be provided. Each of the above mentioned analysis and measurement system is high-end, high speed and super efficient.
The high speed scanning devices like cameras are able to capture upto 10,000 high frame rate per second (fps). More the frame rate of the camera, the lesser will be the capturing time per frame. As the processing time required for the camera to process each captured image buffer is too high which increases the overall decision making time, so instead of using camera as a processing unit, we send the captured image buffer through a commuting media to an external high speed programmable processor (50) which is provided with more RAM and higher CPU speed. This external programmable processor (50) processes the received image buffer more than 90% faster than the camera processor. Even if we consider the image buffer commuting time from camera to external processor through a commuting media, we will save the significant amount of time. So high speed cameras with more

frame rate and a higher speed external processor helps capturing and processing more data per second. So due to increased speed, the camera can analyze a lot more frames in a tiny time slot.
The advanced high speed programmable cameras, advanced X-ray cameras, advanced spectrometer and can be other more are all located in the scanning unit (40). Based on the object to be scanned, one or combination of one or more of this analysis, measurement systems are utilized.
The programmable processor (50) receives scanned parameter(s) of each scanned object passed through the scanning unit (40) and determines grade/category of each scanned object and communicates grade/category characteristics of each scanned object of each set of examination beds to the controller (10). Though, the programmable processor (50) is an external independent device, however, the programmable processor (50) can be in-built with one of the controller (10) or the scanning unit (40).
The ejection mechanism (60) is positioned after the scanning unit (40) such that each object after being scanned is graded/categorized relocates on the transfer mechanism (30) upto the ejection mechanism (60) upon direction of controller (10).
The set of grade/category containers (70) is provided below the ejection mechanism (60) and receive desired graded/categorized objects upon direction of the controller (10). Each grade container (70) receives one grade/categorized of objects.
The return mechanism (80) is used for carrying empty examination beds (31a to 31d) from the ejection mechanism (60) to the feeder (20) without obstructing the scanning unit (40). The return mechanism (80) can be a manual force or a mechanical mechanism, wherein the mechanical mechanism is an intelligent set of examination bed handling mechanism that intelligently handles empty examination beds (31a to 31d) from the ejection mechanism (60) to the feeder (20).

The main non-limiting components of the system for grading and ejecting objects (100), in accordance with the second embodiment as illustrated in FIG. 2, are: at least one a controller (10), at least one feeder (20), at least one transfer mechanism (30), at least one scanning unit (40), at least one programmable processor (50), at least one ejection mechanism (60) that includes a plurality of ejection mechanisms/ejectors (60a to 60d), at least one set of grade/category containers (70) and at least one return mechanism (80).
The feeder (20) is controlled by the controller (10). The feeder (20) is provided on upper portion of one end of the transfer mechanism (30) such that objects falling from feeder (20) are received on the transfer mechanism (30). Moreover, the feeder (20) singulates objects and continuously releases a plurality of sets of objects on the transfer mechanism (30) such that each set of objects in parallel with another set and each object in each set in in-line. The feeder (20) is parallel to a portion of the transfer mechanism (30) under the feeder (20) such that the transfer mechanism (30) relocates/moves each set parallel to another set till the feeder (10) portion. The feeder (20) feeds sets of singulated objects manually and/or automatically.
The transfer mechanism (30) has a plurality of set of examination beds (31a to 31d) for receiving each object. The transfer mechanism (30) below the feeder (20) has the plurality of sets of examination beds (31a to 31d) positioned parallel with respect to each other and receives the plurality of sets of objects. Each set of examination beds (31a to 31d) move/relocates parallel with each other on transfer mechanism (30) till the feeder (20). After the feeder (20), each set of examination beds (31a to 31d) relocates transversely such that each set of examination beds (31a to 31d) moves in series. Also, distance between adjacently disposed sets of examination beds (31a to 31d) is predetermined. Number of examination beds in one set of examination beds (31a to 31d) and number of sets is equal to number of objects released (i.e. capacity of the feeder (20) in one shot of the feeder (20) such that one examination bed (31a to 31d) is fed with one object without any miss from the feeder (20). After, portion of the transfer mechanism (30) under the feeder (20), the transfer mechanism (30) relocate each set of examination beds (31a to 31d) with objects away from said feeder (20) in series upto the ejection mechanism (60) upon direction of the controller (10).

Typically, the transfer mechanism (30) transfer objects in a linear manner or in at least one linear and at least one transverse manners such that the scanning unit (40) configured to receive objects oriented in linear manner.
The scanning unit (40) is provided between the feeder (20) and the ejection mechanism (60) and positioned above or in vicinity of the transfer mechanism (30) such that each object of each set of examination beds (31a to 31d) relocating from the feeder (20) on the transfer mechanism (30) is scanned by the scanning unit (40) upon direction of said controller (10). The scanning unit (40) scans one or more of at least one internal parameter(s) and at least one external parameter(s). In one embodiment, the scanning unit (40) includes one or more scanning devices (not illustrated in Figures).
In one embodiment, the scanning unit (40) is high speed scanning unit. The high speed scanning unit (40) includes an advanced programmable cameras which can be “synchronous”, “asynchronous”, “regular”, “color” or “multi-spectral” cameras, advanced X-ray cameras, advanced spectrometer. Also, multiple spectral light sources, multiple adjustable mirrors/ prisms and an advanced backlighting system can be provided. Each of the above mentioned analysis and measurement system is high-end, high speed and super efficient.
The high speed scanning devices like cameras are able to capture up to 10000 fps. More the frame rate of the camera, the lesser will be the capturing time per frame. As the processing time required for the camera to process each captured image buffer is too high which increases the overall decision making time, so instead of using camera as a processing unit, we send the captured image buffer through a commuting media to an external high speed programmable processor (50) which is provided with more RAM and higher CPU speed. This external programmable processor (50) processes the received image buffer more than 90% faster than the camera processor. Even if we consider the image buffer commuting time from camera to external processor through a commuting media, we will save the significant amount of time. So high speed cameras with more frame rate and a

higher speed external processor helps capturing and processing more data per second. So due to increased speed, the camera can analyze a lot more frames in a tiny time slot.
The advanced high speed programmable cameras, advanced X-ray cameras, advanced spectrometer and can be other more are all located in the scanning unit (40). Based on the object to be scanned, one or combination of one or more of this analysis, measurement systems are utilized.
The programmable processor (50) receives scanned parameter(s) of each scanned object passed through the scanning unit (40) and determines grade/category of each scanned object and communicates grade characteristics/category characteristics of each scanned object of each set of examination beds to the controller (10). Though, the programmable processor (50) is an external independent device, however, the programmable processor (50) can be in-built with one of the controller (10) or the scanning unit (40).
The ejection mechanism (60) is positioned after the scanning unit (40) such that each object after being scanned relocates on the transfer mechanism (30) upto the ejection mechanism (60) upon direction of controller (10). The ejection mechanism (60) includes a plurality of ejection mechanisms (60a to 60d) disposed parallel with each other and eject sets of scanned objects in a logical and controlled sequence. For instance, assuming 4 sets of objects are fed by the feeder (20). So the sequence of flow of sets of objects out from feeder (20) is a first set of objects, a second set of objects, a third set of objects and lastly a fourth set of objects. The scanning unit (40) firstly scans the first set of objects, the second set of objects, the third set of objects and lastly the fourth set of objects. The sequence of ejection in the ejecting mechanism (60), the first set of objects moves towards the last ejecting mechanism (60d), the second set of objects moves towards the second last ejecting mechanism (60c), the third set of objects moves towards the second ejecting mechanism (60b) and the fourth set of objects moves towards the first ejecting mechanism (60a).
The set of grade/category containers (70) is provided below each of the ejection mechanism (60) and receive desired graded/categorized objects upon direction of the

controller (10). Each grade/category container (70) receives one grade/category of objects.
The return mechanism (80) is used for carrying empty examination beds (31a to 31d) from the ejection mechanism (60) to the feeder (20) without obstructing the scanning unit (40). The return mechanism (80) can be a manual force or a mechanical mechanism (intelligent set of examination bed handling mechanism) that intelligently handles empty examinations beds (31a to 31d) from the ejection mechanisms (60a to 60d) to the feeder (20).
In one embodiment the return mechanism is linear and in another embodiment the return mechanism is non-linear and can be of any other type according to the need of the system.
The main non-limiting components of the system for grading and ejecting objects (100), in accordance with the third embodiment as illustrated in FIG. 3, are: at least one controller (10), at least one feeder (20) that includes a plurality of feeders namely a first feeder (20a) and a second feeder (20b), at least one transfer mechanism (30) that includes a first transfer mechanism (30a and 30c) and a second transfer mechanism (30b and 30d), at least one scanning unit (40), at least one programmable processor (50), at least one ejection mechanism (60) that includes a plurality of ejection mechanisms (60a, 60b), at least one set of grade/category containers (70a, 70b) and at least one return mechanism (80).
The first feeder (20a) is oriented and stacked in space with respect to the second feeder (20b). The first feeder (20a) and the second feeder (20b) are controlled by the controller (10). The first feeder (20a) and the second feeder (20b) are provided on upper portion of one end of the respective first transfer mechanisms (30a and 30c) such that objects falling from feeder (20) are received on the first transfer mechanisms (30a and 30c). Moreover, the first feeder (20a) and the second feeder (20b) singulates objects and continuously releases a plurality of sets of objects on the respective first transfer mechanisms (30a and 30c) such that each set of objects in parallel with another set and each object in each set in in-line. The first feeder (20a) and the second

feeder (20b) are parallel to a portion of the first transfer mechanisms (30a and 30c) under the first feeder (20a) and the second feeder (20b) such that the first transfer mechanism (30a and 30c) moves each set of objects parallel to another set of objects till the first feeder (20a) and the second feeder (20b) portion . The first feeder (20a) and the second feeder (20b) feeds sets of singulated objects manually and/or automatically
The first transfer mechanism (30a, 30c) and the corresponding second transfer mechanism (30b and 30d) has a plurality of set of examination beds (31a to 31d) for receiving each objects. The first transfer mechanism (30a, 30c) below the first and second feeders (20a, 20b) has the plurality of sets of examination beds (31a to 31d) positioned parallel with respect to each other and receives the plurality of sets of objects. (Each set of examination beds (31a to 31d) move/relocates parallel with each other on the respective first transfer mechanisms (30a, 30c) till the first and second feeders (20a, 20b).) After the first and second feeders (20a, 20b), each set of examination beds (31a to 31d) relocates transversely such that each set of examination beds (31a to 31d) moves in series. Also, distance between adjacently disposed sets of examination beds (31a to 31d) is predetermined. (Number of examination beds in one set of examination beds (31a to 31d) and number of sets is equal to number of objects released (i.e. capacity of the feeder (20)) in one shot of the feeder (20) such that one examination bed (31a to 31d) is fed with one object without any miss from the feeder (20).) The first transfer mechanism (30a, 30c) and the second transfer mechanism (30b, 30d) are spaced apart at a pre-determined distance, Each set of the first transfer mechanisms (30a, 30c) carry each set of examination beds (31a to 31d) to the second transfer mechanism (30b, 30d) by overcoming the space such that each set of objects sequentially and linearly pass through the scanning unit (40) positioned above space. From the second transfer mechanisms (30b, 30d), objects are carried to the ejecting mechanism (60a, 60b).
In one embodiment, the speed of objects moving through the first and second feeders (20a and 20b) is less than the speed of objects moving through the scanning unit (40). Thus speed of objects moving through the scanning unit (40) is more as the scanning unit (40) is of high speed. After the scanning unit (40), speed of objects moving in the

ejecting mechanism (60a, 60b) is less than the speed of objects at the scanning unit (40). The speed of objects can be changed interchangeably between feeder, scanning unit and ejection unit, but speed of scanning unit is always more.
The scanning unit (40) is above the space formed between the first transfer mechanisms (30a, 30c) and the second transfer mechanisms (30b, 30d) such that each object of each set of examination beds (31a to 31d) carried from the first transfer mechanisms (30a, 30c) and the second transfer mechanisms (30b, 30d) is scanned by the scanning unit (40) upon direction of said controller (10). The scanning unit (40) scans one or more of at least one internal parameter(s) and at least one external parameter(s). In one embodiment, the scanning unit (40) includes two or more scanning devices (not illustrated in Figures). The scanning unit (40) handles objects sequentially received from multiple directions of the first transfer mechanisms (30a, 30c). The first transfer mechanisms (30a, 30c) transfer objects in a linear manner or in at least one linear and at least one transverse manner such that the scanning unit (40) configured to receive objects oriented in linear manner.
In one embodiment, the scanning unit (40) is high speed scanning unit. The high speed scanning unit (40) includes an advanced programmable cameras which can be “synchronous”, “asynchronous”, “regular”, “color” or “multi-spectral” cameras, advanced X-ray cameras, advanced spectrometer. Also, multiple spectral light sources, multiple adjustable mirrors/ prisms and an advanced backlighting system can be provided. Each of the above mentioned analysis and measurement system is high-end, high speed and super efficient.
The high speed scanning devices like cameras are able to capture up to 10000 fps. More the frame rate of the camera, the lesser will be the capturing time per frame. As the processing time required for the camera to process each captured image buffer is too high which increases the overall decision making time, so instead of using camera as a processing unit, we send the captured image buffer through a commuting media to an external high speed programmable processor (50) which is provided with more RAM and higher CPU speed. This external programmable processor (50) processes the received image buffer more than 90% faster than the

camera processor. Even if we consider the image buffer commuting time from camera to external processor through a commuting media, we will save the significant amount of time. So high speed cameras with more frame rate and a higher speed external processor helps capturing and processing more data per second. So due to increased speed, the camera can analyse a lot more frames in a tiny time slot.
The advanced high speed programmable cameras, advanced X-ray cameras, advanced spectrometer and other more are all located in the scanning unit (40). Based on the object to be scanned, one or combination of one or more of this analysis, measurement systems are utilized.
The programmable processor (50) receives scanned parameter(s) of each scanned object passed through the scanning unit (40) and determines grade/category of each scanned object and communicates grade/category characteristics of each scanned object of each set of examination beds to the controller (10). Though, the programmable processor (50) is an external independent device, however, the programmable processor (50) can be in-built with one of the controller (10) or the scanning unit (40).
The first ejection mechanism (60a) and the second ejection mechanism (60b) is positioned after the scanning unit (40) such that each object after being sequentially scanned is graded/categorized and is carried to relocates to respective first ejection mechanism (60a) and the second ejection mechanism (60b) by respective second transfer mechanism (30b, 30d) upon direction of controller (10). Each ejection mechanism (60a and 60b) includes a plurality of ejection mechanisms (i.e. ejectors) disposed parallel with each other and eject sets of scanned objects in a logical and controlled sequence.
The set of grade/category containers (70) is provided below each of plurality of ejection mechanisms (i.e. ejectors) of the ejecting mechanisms (60a, 60b) and receive

desired graded/categorized objects upon direction of the controller (10). Each grade container (70a, 70b) receives all grades/category of objects.
The return mechanisms (80) are used for carrying empty examination beds (31a to 31d) from the ejection mechanisms (60) to the feeders (20) without obstructing the scanning unit (40). The return mechanism (80) can be a manual force or a mechanical mechanism (also known as intelligent set of examination bed handling mechanism) that intelligently handles empty examinations beds (31a to 31d) from the plurality of ejection mechanisms (60a, 60b) to the first and second feeders (20a and 20b).

The objects from feeder (20) move linearly towards the plurality of ejection mechanisms (60a to 60d). The objects thus move in linear motion as well as transverse motion.
In another embodiment as per system of FIG. 3, the method includes feeding, by the first feeder (20a) and the second feeder (20b), in one shot, a plurality of sets of objects on a plurality of sets of examination beds (31a to 31d) provided on the first transfer mechanisms (30a and 30c) upon direction of the controller (10) such that one examination bed (31a to 31d) receives one object. Moving objects by the first transfer

mechanisms (30a and 30c) under the first feeder and the second feeder (20a, 20b) such that each set of objects move parallel with respect to adjacent sets of objects. Relocating, the set of objects transversely from the first and second feeders (20a, 20b) in direction of the first and second ejection mechanisms (60a, 60b) such that adjacently disposed sets of objects are in-line with each other. Moving objects in-line from the first ejection mechanism (60a) and the second ejection mechanism (60b) through the space.

The scanning unit (40) scans one or more of at least one internal parameter(s) and at least one external parameter(s).
The programmable processor (50) processes received scanned parameter(s) of each scanned object passing through the scanning unit (40) and determine grade/category of each scanned object and communicate grade/category characteristics of each scanned object of each set of examination beds (31a to 31d) to the controller (10). Relocating each set of scanned and graded/categorized objects towards the plurality of ejection mechanisms (60a and 60b). Each set of object changes direction to transverse direction such that each set of objects moves parallel with respect to another adjacent set of objects in the ejecting mechanism (60a and 60b).

Returning empty examination beds from the plurality of ejection mechanisms (60a and 60b) to the first feeder (20) without obstructing the scanning unit (40) by the return mechanism (80). The objects from the first feeder (20a) move linearly towards the plurality of ejection mechanisms (60a and 60b). The objects thus move in linear motion as well as transverse motion. Also, the speed of objects passing through the scanning unit (40) is more than the speed of objects passing through the first and second feeders (20a, 20b) and the speed of objects moving in the ejecting mechanisms (60a, 60b). The scanning unit (40) handles objects sequentially received from multiple directions of the multiple directions of the first and second transfer mechanisms (30a, 30c and 30b, 30d). The first and second feeders (20a, 20b), the first transfer mechanism (30a, 30c), the second transfer mechanism

(30b, 30d) and the ejection mechanisms (60a, 60b) are synchronous with each other by the controller (10).
In accordance with the present disclosure the term external parameter shall refer to any possible extrinsic/physical characteristics/features of each object of interest which may include but not limited to volumetric size, shape, color, surface properties, or any other characteristics.
In accordance with the present disclosure the term internal parameter shall refer to any possible intrinsic/biochemical characteristics/features of objects which may include depth/thickness of shell, size, shape of kernel inside shell or light scattering, emitting, refracting or deviating properties of an object or related to any possible internal properties of each object of interest.
In one exemplary embodiment, the objects to be scanned are cashew kernels. For cashew kernels we need advanced programmable cameras which can be synchronous, asynchronous, regular or color with multiple adjustable mirrors/ prisms for multi-reflectance and multi-angle views and an advanced backlighting system for uniform background capture.
In another exemplary embodiment, the objects to be scanned are raw cashew nut. For raw cashew nuts we need X-ray cameras to detect the depth of kernel inside the shell for obtaining better cutting efficiency with an advanced backlighting system for uniform background capture. The X-ray motion analysis can visualize specific structure in an object. This can also be used in analysis of fruits to detect their ripeness and use for specific purposes.
In yet another exemplary embodiment, the objects to be tested are high value commodity like diamonds. The feeding of diamonds can be done manually to place it properly with a required orientation and angle so that the high-speed spectral cameras from the central scanning system can test its internal structure and flaws. Also with the proper orientation and angle the spectrometer can measure light that

is emitted, scattered and/or absorbed by the diamond to study, identify and quantify the diamond.
The present disclosure provides many advantages such as the system for grading and ejecting objects has a high speed scanning and processing unit for performing scanning and processing of each object in fraction of time. The scanning system can handle objects received sequentially from one or multiple directions and hence scans multiple objects in less time. The system can be oriented in various forms such that each feeder and each ejecting mechanism communicate with one scanning unit thus providing efficient scanning and grading in a synchronized manner.
Though the present disclosure is described by disclosing the scanning device (40) as a camera, however, the present disclosure is not limited to use of the cameras for scanning and other scanning device with different scanning technologies like different types of radition (X-rays or lazer rays) or any other type scanner are well within the scope of the present disclosure.
As will be readily apparent to those skilled in the art, the present disclosure may easily be produced in other specific forms without departing from its essential characteristics. The present embodiments is, therefore, to be considered as merely illustrative and not restrictive, the scope of the disclosure being indicated by the claims rather than the foregoing description, and all changes which come within therefore intended to be embraced therein.
