Abstract: An apparatus for use in a fluid medium which activates at a deeper depth and then releases at a lesser depth. A rod depresses a spring in a housing. The rod is prevented from being ejected from the housing by a ball bearing which engages between openings in the rod and the housing. When in use, the pressure exerted by the fluid medium forces the rod deeper into the housing. When the first depth is reached the ball bearing disengages from the rod and the device is activated. As the activated apparatus rises, the pressure on the rod decreases and the rod moves out of the housing. When the deployment depth is attained the housing floods and the rod is ejected.

Abstract: The invention pertains to a ball joint assembly which includes a ball stud received in a swivel socket of a supporting body. Some of such assemblies are classed as quick disconnects, meaning that the ball stud may be conveniently assembled and disassembled as desired. In another class, the bodies are substantially cylindrical with the sockets forming a pair of diametrically opposed feather edges. In drilling the sockets, it is not uncommon for a burr to be formed about the perimeter, and for this burr to be bent inwardly thereby obstructing the free insertion of the ball stud into the socket. Also it is not uncommon for the feather edges to be bent inwardly resulting in the same problem. By counterboring the socket, the burr is removed and the feather edges are flattened which not only solves the obstruction problem but may also provide other advantages.
