Abstract: A hydrostatic testing tool for testing containers, hoses or the like under high pressures. The testing tool having a coupling that threadably engages a threaded aperture of a test container without having to be rotated into the threaded aperture. The hydrostatic testing tool may be hooked up to a source of pressurized medium and the tool includes a container-engaging head having a plurality of collet segments that each have a threaded surface that can expand radially outward, partially due to the force of the pressurized medium, to engage a threaded aperture of the test container, allowing for the formation of a liquid and/or gas tight seal under high pressures. The testing tool further includes an actuating unit connected to the head that controls the movement of the collet segments with a piston or the like.

Abstract: A vacuum head (10) for pick-up and placement of integrated circuit devices (16, 16'). The apparatus includes an outer housing (18) enclosing therewithin an inner tip assembly (34). The inner tip assembly (34) is disposed for reciprocation through and past an orifice (24) formed in a fitting (26) closing one end of the casing (20) of the outer housing (18). The inner tip assembly (34) has formed therein a shoulder (76) which, when the assembly (34) is moved to an extended position, can engage a seat (78) formed in an inner surface of the fitting (26). An O-ring (80) can be interposed between the shoulder (76) and the seat (78) to preclude vacuum generated in vacuum chamber (30) from being directed other than through an orifice (68) formed in the inner tip assembly (34). An air cylinder (48) is provided to actuate the inner tip assembly (34) for movement between retracted and extended positions.
