Abstract: A cable tie includes an elongate generally planar strap and a head. The head of the cable tie includes an aperture therethrough for insertably accommodating the strap. The head of the cable tie also includes a barb embedding surface adjacent the aperture through the head. A metallic locking barb is embedded in the embedding surface in a direction substantially parallel to the aperture in the head. The metallic locking barb is bent to form an obtuse angle so that the metallic locking barb extends into the aperture in the head to permit movement of the strap in an insertion direction and to prevent substantial movement of the strap in a withdrawal direction.

Abstract: A bundling tie having a head at one end, a tail at the other end, and a central strap body therebetween. The head includes a strap ingress face for receiving the strap and a strap egress face from which the inserted strap exits the head. The head further includes a central passageway in communication with the strap ingress face and the strap egress face for receipt of the tail. A metallic locking barb is embedded into a flexible foundation in the head. The flexible foundation is partially defined by a channel around the foundation. The channel provides increased barb rotation upon strap insertion into the head while also providing a stop surface that requires greater barb deflection upon attempt to withdraw the strap from the head.

Abstract: A mounting block for a plastic anchor base has a pressure sensitive covering (adhesive, magnetic, or the like) its lower surface so that it may be secured to a chassis, at any convenient location. The mounting block includes a hole of conventional dimensions leading to an internal cavity which receives and encloses the part of the anchor base which protrudes through a mounting hole. In some embodiments, the internal cavity also contains opposing cam surfaces which urge the resilient members on the anchor base to a released position when the anchor base is rotated. This way, the anchor base may be removed from the mounting block by giving the anchor base a partial turn and pulling. Another feature provides capture notches for receiving and locking said barbs when the anchor base is rotated.

Abstract: This is concerned with a voltage tester of the so-called solenoid type and is more specifically concerned with such a voltage tester which is constructed and arranged to also test the continuity of its leads and prods or contacts.

Abstract: A releasable cable clamp having a base which can be affixed to a work surface. The base comprises a planar member and an upright pedestal. Connected to the pedestal is a strap which extends therefrom in a generally arcuate manner forming a cable-securing loop. The strap has a catch formed near one end. The catch operates in conjunction with a closure device to close and lock the clamp. A releasing latch is connected to the closure device. The latch and strap have an interlock feature which becomes engaged when the clamp is closed. Actuating the releasing latch causes the strap to be moved such that the catch is disengaged from the closure device, allowing the clamp to open.

Abstract: A hand-held ground fault interrupter for checking the operation of a ground fault protected wall receptacle. The blades of an electrical terminal protrude from one end of a housing which contains a potentiometer and electrical connecting means between the potentiometer and the blades. The tester creates a ground fault by allowing current to leak to the ground path, the amount of leakage varied by the potentiometer. A properly operating ground fault interrupter senses the leakage and is designed to trip when it sees a selected level of current leakage. Tripping at lower levels or failure to trip at higher levels indicates a defective interrupter. Recesses in the sides of the housing provide access to the potentiometer dial for rotating the dial and reading a label affixed thereto.
