Abstract: An anti-rotation locking assembly for releasably fastening automotive exhaust pipes and exhaust manifolds to an engine block is disclosed comprising a threaded bolt with hex-wrenching recess and a hyperbolic locking plate with hex-stud which fits into the wrenching recess of the bolt and is attached thereto by cotter pin or Q clip. The locking plate has a contour which mates with said exhaust pipe and thereby prevents the bolt from working loose due to vibration of the engine.

Abstract: This improved cattle stanchion discloses an essentially coplanar and rectangular frame for automatically locking and manually releasing the heads of cattle. The frame unit consists of three vertical bars and two essentially horizontal bars, the top of which being slightly arched upwardly to form an apex over the center of the frame while the bottom bar is slightly arched downwardly to form a nadir under the center of the frame. These arches define an arc of travel for the central pivotally mounted vertical bar with an annular ring extension around the top arch of the frame. The annular ring cooperates with a locking mechanism consisting of pairs of elliptical latching sleeves mounted linearly apart and above the frame unit on a horizontal bar which may be operated by an attendant to either lock or unlock the stanchion.

Abstract: An electrical test connector and method have been invented for diagnostically testing the FORD vehicle Speed Control System on 1973 and later models, said connector designed to fit into the FORD wiring harness, and said connector further comprising a plurality of circuits, indicator lights and switches corresponding to the method by which it is used.

Abstract: A golf ball washing machine has been invented where a detachable upper vibrating trough may receive numerous golf balls and dispense them individually into a spiral cage encircling a rotating brush in a lower water tank where the golf balls are entrapped between the brush and cage interior and are scrubbed as they are forced along the interior of the spiral cage to an exit leaving dirt and debris in the tank.
