Abstract: A control mechanism for use with a hydraulic locking device to permit the device to be unlocked under control of an operator. The control mechanism includes a lever assembly fastened to the piston rod of the hydraulic control device and connected by a cable to a remotely located push button assembly. When the operator presses the push button, the cable is drawn causing the lever assembly to move an operating rod of the hydraulic locking device to a release position thereby unlocking the device. The lever assembly can be installed on the hydraulic locking device without the use of tools by sliding a spring clip which is a non-removable portion of the lever assembly. A threaded collar permits the effective length of the conduit to be altered to adjust the stroke of the mechanism. The spring cip is made to serve a dual purpose.

Abstract: A precision rotary indexing fixture is disclosed of the type including a top plate adapted to have work pieces mounted thereon with the work plate indexed to any of a plurality of precision rotary positions. The precision locking of the top plate is achieved by serrated coupling rings, one mounted on the outer periphery of the top plate, the other mating ring mounted on a base structure. The top plate is locked in various index positions by the application of disc spring sets acting on the top plate through an annular piston and a set of bearing elements mounted in opposed grooves in the piston and a race ring mounted to the top plate. The fluid forces acting on the piston acts to release the locking pressure exerted by the disc spring sets and release the coupling serration engagement during indexing of the top plate.

Abstract: An intermittent motion gear apparatus for positioning a control valve to an open position in response to a predetermined input. An input greater than the predetermined input has no effect on the valve's position but sets a mechanical servo for a desired output corresponding to an operational position of a motor. When the operational position of the motor is reached, a feedback signal acts on the intermittent motion to move the control valve to a null or closed position.

Abstract: A mechanism for providing differential control of the opening of the throttle valve which controls the amount of air introduced into the induction manifold of an internal combustion engine. The angle of opening of the throttle valve changes with a predetermined law of variation with respect to the displacement of a member controlled directly by the throttle pedal; this member has cam faces formed thereon for successive engagement by different rollers spaced along a transmission member the angular displacement of which is directly related to the angular displacement of the throttle valve. Transmission of movement from the transmission member is by means of meshing toothed sectors providing a fixed ratio, or by way of direct connection to the butterfly spindle.
