Abstract: A high mast lighting system for highways, airports, parking lots and the like of the type in which light bulbs are mounted on a ring shaped platform of a diameter such that it surrounds the mast and can be raised and locked into a lighting position at the top of the mast by operation of cables extending to the base of the mast. The invention is particularly directed to a novel locking and supporting mechanism for support of the lighting ring platform at the top of the mast independent of its lift cables and in which the locking pawls supporting the ring can be disengaged from their supporting position by operating the lift cables from the base of the mast to permit lowering of the ring for maintenance such as a change of bulbs.

Abstract: An electrical cable connector of the multi-contact type wherein pin contact members of a male plug component engage and make electrical connection with corresponding spring finger contact members of a female receptacle, the pin and spring finger members each being threadably secured in a wire lead connecting base portion mounted in an insulating matrix in the plug and sockets components, respectively. The base portion for both the pin and spring finger members can be identical, thus providing a common base in a three piece contact system wherein a common base will receive either the male pin or the female spring finger members and allow ready removal of the contact members for replacement without disconnection of lead wires in instances of damage such as might be caused by dropping or rough handling of the connector.
