A baffle for a food waste disposer to reduce noise is disclosed. The baffle has a diaphragm that allows solid and liquid waste to pass through the diaphragm, and accordingly does not substantially affect the normal operation of the disposer. However, because the baffle covers the central opening in
A baffle for a food waste disposer to reduce noise is disclosed. The baffle has a diaphragm that allows solid and liquid waste to pass through the diaphragm, and accordingly does not substantially affect the normal operation of the disposer. However, because the baffle covers the central opening in the conventional mounting gasket of the prior art, a direct path from the grinding mechanism in the disposer to the sink is blocked, thus muffling the noise coming from the grinding mechanism. Additionally, the disclosed baffles are preferably, but not necessarily, designed so as to create a water dam on their surface by impeding the flow of water from the sink faucet in a way to create a pool of water. The disclosed baffles may be installed in the drain opening of a sink above the conventional mounting gasket, although other embodiments are also disclosed.

The device of claim 1, wherein the stationary card bumper is fixedly coupled to a base plate. 5. The device of claim 1, wherein the stationary card bumper is of sufficient width to ensure that the test card will maintain a parallel posture relative to a reentry slot of the card reading device. 6. The device of claim 1, further comprising a housing assembly roller coupled the side faces of the housing assembly proximate to the front face and abutting a base plate. 7. The device of claim 1, wherein the shift of the position of the test card allows the test card to be reinserted into the card reading device, such that the card reading device is able to detect a presence of the test card. 8. An automated card retrieval and reinsertion device for card reading device testing, comprising: a housing assembly comprising a front face proximate to the card reading device; a shaft coupled to a back face of the housing assembly; an upper gripper roller assembly, wherein an axis of the upper gripper roller assembly resides within a plurality of slots in side faces of the housing assembly; a lower gripper roller assembly, wherein an axis of the lower gripper roller assembly is fixedly coupled to the side faces of the housing assembly, wherein the upper and lower gripper roller assemblies grip a test card; a plurality of springs coupled to the axes of the upper and lower gripper roller assemblies; a microswitch coupled to the housing assembly, wherein the shaft moves the housing assembly away from the card reading device when the microswitch is in a first state, wherein the shaft moves the housing assembly toward the card reading device when the microswitch is in a second state, wherein the microswitch is placed into the first state by the test card when the test card is retrieved from the card reading device; and a stationary card bumper proximate to the back face of the housing assembly, wherein a position of the test card is shifted toward the card reading device when the test card abuts the stationary card bumper, wherein the shifting of the test card places the microswitch in the second state. 9. The device of claim 8, further comprising an air cylinder, comprising: the shaft, wherein the shaft retracts when an air supply is provided to the air cylinder, wherein the air supply is provided when the microswitch is in the first state; and an internal return spring, wherein the internal return spring extends the shaft when the air supply is not provided to the air cylinder, wherein the air supply is not provided when the microswitch is in the second state. 10. The device of claim 8, wherein the stationary card bumper is fixedly coupled to a base plate. 11. The device of claim 8, wherein the stationary card bumper is of sufficient width to ensure that the test card will maintain a parallel posture relative to a reentry slot of the card reading device. 12. The device of claim 8, further comprising a housing assembly roller coupled the side faces of the housing assembly proximate to the front face and abutting a base plate. 13. The device of claim 8, wherein the shift of the position of the test card allows the test card to be reinserted into the card reading device, such that the card reading device is able to detect a presence of the test card. 14. An automated card retrieval and reinsertion device for card reading device testing, comprising: a housing assembly comprising a front face proximate to the card reading device; an air cylinder, comprising: a shaft coupled to a back face of the housing assembly, wherein the shaft retracts when an air supply is provided to the air cylinder, and an internal return spring, wherein the internal return spring extends the shaft when the air supply is not provided to the air cylinder; an upper gripper roller assembly, wherein an axis of the upper gripper roller assembly resides within a plurality of slots in side face
