4. PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention and the manner in which it is to be performed.

BACKGROUND OF THE INVENTION
Manufacturing process of compact fluorescent lamp includes an important process called as aging. During the aging process, the lamps after manufacturing are tested for various range of Voltages. The lamps are placed on belt having electric supply of various Voltages.
A unit is present in the aging machine to hold various lamps to be tested. The electrical connections from the lamps need to be connected to the electrical plate. This connection should however not be static but allow movement over the electrical plate. For this purpose generally electric brushes are used which run over the electrical plate during the process of aging. This wire type electric brush moves over the electric supply to draw power of various Voltages.
However it is observed that due to the wire type shape of the contact brush there exist several disadvantages, which may result in loss of production. Few amongst the disadvantages includes the wear and tear in wire type contact brush, which further demands frequent replacements. Further, due to continuous movement of the brushes over the electric supply plate, there is uneven deformation in the feathers of the brushes, which results in unequal power supply. This also increases the chances of sparks.
There is therefore required a system which provides a safe, efficient means of drawing power from the electrical plates in the aging process to be transferred to various lamps.

SUMMARY
An aging electrical contact for drawing power from an electrical plate in an aging machine of lamps is described. In one embodiment the aging electrical contact comprises of a cylindrical roller which would run on the electrical plate during the aging process for drawing power.
In one embodiment of the present invention the aging electrical contact for drawing power from an electrical plate in an aging machine of lamps comprises of a cylindrical roller free to rotate about central axis on the electrical plate. A support hook is provided to support said roller and grip it along the central axis restricting lateral movement of the roller. A spring is attached to the support hook on one side and to a connector block on the other side of the spring.
A roller guide plate is provided fixed on one end to the connector block and having the other end free. During movement of the aging electrical contact the roller guide plate restricts motion of the support hook beyond the plane of the roller guide plate.
The aging electrical contact provided herein enables right pressure during movement of the contact over the electrical plates. Also, the chances of sparks are reduced. The life of the aging contact is therefore considerably high and the aging machine can be operated for longer time before needing replacements of the contacts.
The aging electrical contact also makes the process economical by reducing the use of multiple contacts for each lamp. The wear and tear of the plates is also reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
An aging electrical contact for drawing power from an electrical plate in an aging machine of lamps is described. In one embodiment the aging electrical contact comprises of a cylindrical roller which would run on the electrical plate during the aging process for drawing power.
In one embodiment a fastening means is provided on the aging electrical contact for fastening it to the unit holding various lamps undergoing the process of aging. The fastening means provided is electrically connected to various lamps to be tested. A roller guide plate is also provided in the aging electrical contact to support it during movement thereof over the electrical plate.
In the following description, for purpose of explanation, specific details are set forth in order to provide an understanding of the invention. It will be apparent, however, to one skilled in the art that the invention may be practiced without these details. One skilled in the art will recognize that embodiments of the present invention, some of which are described below, may be incorporated into various assembly line aging processes. It is understood that one skilled in art may modify or change the data used in the examples described in the specification.
Reference in the specification to "one embodiment" or "an embodiment" means that a particular feature, characteristic, or function described in connection with the embodiment is included in at least one embodiment of the invention. The

appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.
An aging electrical contact for drawing power from an electrical plate in an aging machine of lamps is described with reference to figure 1. The aging electrical contact comprises of a cylindrical roller 103 free to rotate about central axis 105 on the electrical plate. A support hook 107 is provided to support said roller and grip it along the central axis restricting lateral movement of the roller.
A spring 109 is attached to the support hook on one side and to a connector block 111 on the other side of the spring. The spring enables flexibility for the motion of the roller contact over the electrical plate in the aging process.
A roller guide plate 113 is provided fixed on one end 113a to the connector block and having the other end 113b free. During movement of the aging electrical contact the roller guide plate restricts motion of the support hook beyond the plane of the roller guide plate. This also ensures correct pressure between the contact and the plate for continuous transfer of power from the electrical plates to the aging electrical contact.
As shown in a side view of the aging electrical contact as per one embodiment of the present invention in figure 2, the aging electrical contact moves in a direction away from the location of the roller guide plate.

A fastening means 219 may be provided on the said connector block to fasten said aging electrical contact to a unit 240 holding said lamps needing power through said aging electrical contact.
An isometric view of the aging machine of lamps having the aging electrical contact as per one embodiment of the present invention is shown in figure 3. The aging electrical contact 305 is fixed to the unit 315 holding various lamps which need to be taken through the process of aging. The aging electrical contact is connected to the unit 315 and runs over the electrical plate 350 for drawing current therefrom. The power is transmitted from the cylindrical roller to the spring and further to the various lamps (303a-h) being aged. It may be noted here that the same electrical contact is electrically connected to various lamps.
The aging electrical contact provided herein enables right pressure during movement of the contact over the electrical plates. Also, the chances of sparks are reduced. The life of the aging contact is therefore considerably high and the aging machine can be operated for longer time before needing replacements of the contacts.
The aging electrical contact also makes the process economical by reducing the use of multiple contacts for each lamp. The wear and tear of the plates is also reduced.
The foregoing description of the invention has been described for purposes of clarity and understanding. Although embodiments of the present invention have been described relative to a few standards, and associated attributes therein, one skilled in the art will recognize that the present invention is also very much applicable to other

such methods and systems. It is not intended to limit the invention to the precise form disclosed. Various modifications may be possible within the scope and equivalence of the appended claims.
