Abstract: An anti-theft system is provided for articles such as modular equipment installed into vehicles with Allen type machine bolts. The system employs a monolithic insert member which is bonded within the hexagonally contoured depression in the head of the machine bolt, and has a protruding portion having a distinctively shaped keying configuration. A turning tool is provided having a handle and a shaft. The distal extremity of the shaft has a recess having a configuration adapted to receive the keying configuration of the insert member.

Abstract: Improvements to a torque-type peach pitter and method, during each cycle of which a peach is presented to a pair of peach bisecting and pit gripping blades for cutting the flesh of the peach to its pit at its suture plane and gripping the edges of the pit to hold it stationary and wherein the peach halves are twisted to separate them from the held pit. The improvements reside in a pre-slitter blade positioned to cut a portion of the peach flesh at the suture plane prior to its presentation to the peach bisecting and pit gripping blades.The peach pitter includes a normally inoperative curved spoon which is extended upon the detection of a split or defective pit and serves to cut such pit from the peach. The pre-slitter blade detects the absence of a peach in any pitting cycle and triggers means to disable the spoon operating mechanism so that the spoon will not be extended during such cycle.

Abstract: In a peach pitter of the type including a pair of blades which both bisect the peach and grip the peach pit, a pair of jaws which twist the peach halves to remove them from the pit, and an aligner which orients the peaches so that their suture planes lie in the plane of the blades, a transfer mechanism is disclosed which accurately feeds individual, oriented peaches from the aligner to the blades in a sequence which minimizes the time required. A pair of claws grasp a peach at a transfer point on the aligner when it is momentarily substantially stationary and immediately carry the peach through an arc toward the blades.As the peach is impaled on the lower of the pair of blades, the upper blade descends to grip the pit. The claws, which are specially designed to insure that the peach is properly aligned with the pitting axis extending between the blades, are then released from the peach and rapidly returned to the transfer point in spread-apart condition ready to receive the next peach.

Abstract: A peach pitter of the torque type in which the space between the pit gripping teeth on the peach bisecting blades at the pitting station is open at both ends and each successive peach is fed into said space through one open end and the preceeding pitted peach and separated pit are discharged out of the other open end of said space.
