Abstract: A hopple for developing a trotting gait for horses which includes two sets of diagonally disposed hopple loops which encircle a horse's legs and which are connected so as to fetter the horse's legs diagonally through a motion transfer assembly mounted beneath the horse's belly and which assembly permits the front and rear legs of the horse to be linearly restrained so that the legs are diagonally fettered without the imposition of lateral stress.

Abstract: A handling and loading system for relatively large caliber ammunition used by automatic weapons such as 20 mm to 40 mm rapid fire guns carried by military aircraft. The system includes an apparatus for automatically removing live rounds of ammunition from a belt of indeterminate length having a plurality of individual containers and loading such ammunition into the armament system of the aircraft while simultaneously removing expended shell casings from the aircraft and inserting the same into the containers which can then be returned for reloading.

Abstract: A harness racing hitch in which the horse and the sulky are coupled together allowing the horse improved freedom to lean into the turns of a racetrack, to pivot between the sulky shafts and to be able to move up and down with respect to the sulky. The sulky shafts are interconnected by a yoke which overlies and is attached to the saddle of the horse harness by a coupling allowing the horse limited but sufficient free movement in all three planes of motion.
