Abstract
Abstract Apparatus for use with a food slicer comprising a conveyor for location adjacent to the said slicer and adapted to receive slices of food as they are cut by the slicer; a pump for generating hydraulic pressure, a motor driven by said hydraulic pressure; passageways between said pump and said motor; means for drivingly connecting said motor to said conveyor; a flow limiting valve in the passageway between the pump and the motor for limiting the speed at which the said motor drives said conveyor; and means for periodically increasing the fluid flow to the motor temporarily to accelerate said motor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
Apparatus comprising, in combination, a conveyor for receiving slices of a food stuff as they are cut by a slicer, a pump for generating hydraulic pressure, a motor driven by said hydraulic pressure, means defining a fluid flow path between said pump and said motor, means for drivingly connecting said motor to said conveyor, a preset flow control valve in the flow path between the pump and the motor for limiting the speed at which the said motor drives said conveyor, and means for temporarily by-passing said control valve thereby to increase the fluid flow to said motor to accelerate the motor.
Claim 2
Dependent Claim
102 words
Apparatus comprising, in combination, a conveyor for receiving slices of a food stuff as they are cut by a slicer, a pump for generating hydraulic pressure, a motor driven by said hydraulic pressure, means defining a fluid flow path between said pump and said motor, means for drivingly connecting said motor to said conveyor, a preset flow control valve in the flow path between the pump and the motor for limiting the speed at which the said motor drives said conveyor, and means for temporarily by-passing said control valve thereby to increase the fluid flow to said motor to accelerate the motor.
Claim 3
Dependent Claim
101 words
Apparatus comprising, in combination, a conveyor for receiving slices of a foodstuff as they are cut by a slicer, a pump for generating a fluid pressure, a motor driven by said fluid pressure, means defining a fluid flow path between said pump and said motor, means for drivingly connecting said motor to said conveyor, a preset flow control valve in the flow path between the pump and the motor for limiting the speed at which said motor drives said conveyor, and means for temporarily by-passing said control valve thereby to increase the fluid flow to said motor to accelerate the motor.
Claim 4
Dependent Claim
101 words
Apparatus comprising, in combination, a conveyor for receiving slices of a foodstuff as they are cut by a slicer, a pump for generating a fluid pressure, a motor driven by said fluid pressure, means defining a fluid flow path between said pump and said motor, means for drivingly connecting said motor to said conveyor, a preset flow control valve in the flow path between the pump and the motor for limiting the speed at which said motor drives said conveyor, and means for temporarily by-passing said control valve thereby to increase the fluid flow to said motor to accelerate the motor.
