Abstract: A linear drive for use in air and space travel converts the rotational drive of an electromotor into a linear motion of a runner which is secured to at least one flexible coupling member. The flexible coupling member runs around at least one guide member at one end thereof, and around a drive wheel driven by the electric motor at the other end of the flexible coupling member. The rotating drive wheel and the guide member both change the movement direction of the flexible coupling member, whereby the runner can run back and forth between the drive wheel and the guide member.

Abstract: A camshaft has a deactivatable cam which is selectively couplable to or releasable from the camshaft by a coupling pin which is transversely displaceable in a recess in the camshaft. To move the coupling pin between its connecting position, in which it engages a coupling recess in the cam, and its release position, in which it is retracted within the confines of the camshaft, the face of the coupling pin opposite the coupling recess forms a pressure chamber in which variable pressure is controlled by a displaceable control piston. A high pressure is applied to move the coupling pin into its connecting position and a lower pressure is applied to maintain the coupling pin in the connecting position, while a further reduced pressure is applied to retract the coupling pin into its release position.

Abstract: The present invention relates generally to a cutting system for vegetables, including potatoes, which includes a conveyor for transporting food product to the general vicinity of a rotating cutting blade. The conveyor generally aligns the food product and arranges it in a single row. The conveyor introduces the food product between a pair of endless belts which include contoured paddles on their mating surfaces to receive the food product and drive it toward the cutting knife.
