Abstract: The turn signal system of the invention utilizes a timing circuit to electrically activate and deactivate the flashing turn signal. The invention system also utilizes a pair (left, right) of auxiliary, spring-loaded, momentary contact, normally open switches arranged such that if the driver actuates the turn signal lever for a turn, even though the lever is in the actuated position for that turn, the turn signal flashing circuit is reactivated by the momentary closing of the auxiliary switch and the cycle is restarted. The system of the invention is also characterized by the timing circuit being dependent for its operation on signals received from the vehicle's speed sensor such that the timing circuit will not operate unless there is a signal from the speed sensor to indicate the vehicle is moving.

Abstract: The connector device comprises a male plug and a female receptacle, each of which has a housing with a central tubular component and a cavity extending therethrough and adapted to receive an end of an electrical conduit. Both the plug and receptacle include means for aligning the electrical pathways therein and for sealing the conduits, plug and receptacle against elevated temperature and corrosive gases, etc. The central tubular components are electrically insulated. The male plug has a plurality of spaced parallel connector pins extending forwardly from the front end of the plug's tubular component and spaced inwardly of a plug sleeve. The receptacle tubular member is disposed within a sleeve and carries a pin receiver on the front end thereof, which receiver bears a plurality of spaced parallel passageways extending longitudinally of the tubular member and containing electrical connectors therein for interconnection with an electrical conduit at the rear of the female receptacle.

Abstract: A cable for high frequency use in an environment with high and varying thermal changes whereby the thermal expansion of the cable is controlled by having a highly electrically conductive metal bonded to a metal of low coefficient of thermal expansion relative to the high electrically conductive metal. This is accomplished by providing a thin layer of highly electrically conductive metal over an inner core of a metal of low coefficient of thermal expansion. The cable can also utilize a similar bonded metal configuration for an outer concentric conductive sheath having a mineral dielectric between conductors that also has a low coefficient of thermal expansion.
