Abstract: A chip carrier structure for containing a chip carrier having electrical contact pads having a positioning structure for the chip carrier and a slotted structure mated to form a mated structure containing said chip carrier, the slots of the slotted structure being in alignment with the pads of the chip carrier to provide electrical and mechanical access to the pads from the exterior to the interior of the mated positioning and slotted structures.

Abstract: A bladder shaped to conform to the form of the sonar transducer housing of a torpedo in which it is located compensates for volume changes because of temperature changes of the oil which fills the transducer housing. The bladder also compensates for the change in water pressure produced by the depth at which the torpedo is operating. The bladder is sufficiently stiff so that it maintains a predetermined shape substantially midway between its fully extended and fully compressed position during the time that the housing is air evacuated and then filled with oil at near atmospheric pressure. The bladder is thus capable of expanding or contracting to accommodate changes in the volume of the contained oil as the temperature of the oil changes. The bladder is preferably made of a material without substantial spring force or stretch.

Abstract: A connector holder assembly for use with a wiring harness wiring has a frame adapted to hold a connector contained with the frame by a snap-on cover. A pair of jackscrews secures the frame to a mating connector. The frame is cast with two arms at each end of a back plate. The arms have inboard slots for receiving jackscrews. The jackscrews are retained within the slots by a connector which has detents at its ends which engage the jackscrews when the connector has been positioned between the jackscrews. A stiff spring-like metallic retainer cover for the connector which is snap fastened to the arms of the frame retains the connector between the frame arms and against the backplate of the frame against the force produced on the connector by the wiring harness attached thereto.
