Abstract: A termination for cables of the type having a central bundle of conductors surrounded by strength members includes a rigid sleeve closely surrounding the bundle of conductors beneath the strength members and a rigid housing surrounding the strength members outwardly of the sleeve. The strength members are encapsulated in a hardenable material to define an enlarged lug closely received between said sleeve and housing. The housing and lug have cooperating cam surfaces for compressing the lug between the housing and sleeve when a pulling force is applied to the housing. The outer diameter of the housing is cylindrical and has a diameter approximately the same as the diameter of the cable outer cover.

Abstract: Excessive pressure is relieved in a fluid actuator by controlled destruction of an internal extensible diaphragm without damage to the exterior structural integrity of the actuator. Upon occurrence of such abnormal excessive pressure in the actuator pressure chamber, the diaphragm, which is otherwise substantially supported, is permitted to deform at a known location until fracturing thereof occurs to release fluid from the pressure chamber. In one form the invention comprises an opening in the actuator guide cap and in other forms comprises openings in the actuator piston or an enlargement in part of the guide cap.
