A surge arrester which includes a pair of spaced metal electrodes and a semiconductor element interposed between the metal electrodes and in contact with at least one of the metal electrodes. The semiconductor element functions at least partially to bridge a gap between the metal electrodes with such gap serving as a current path between the metal electrodes in the event a voltage applied across the metal electrodes exceeds a firing voltage of the surge arrester. The semiconductor element includes a metal coating on at least a substantial portion of its outer surface which is in contact with the at least one metal electrode. The coating includes a gap between the electrodes and the gap may include a notch in the gap.

Surge arrester

A conduit support clamp comprising a U-shaped body having resilient legs. Each leg terminates in a foot section extending toward the other leg, one foot overlapping the other foot. The clamp includes a low profile latch to connect the foot sections. The latch includes a catch having compound angles whereby the overlapping foot sections present a substantially smooth outer surface and in which neither foot section extends beyond the opposing leg whereby the clamp may be manually latched.

Conduit clip

A welding apparatus and method characterized by an electrically activated high temperature igniter with a pair of lead wires adapted to be connected to a high energy source of current and a high resistance bridge between the leads. The bridge is coated with an ignition material comprising a mixture of fine aluminum, one or more metal oxides or oxygen containing compounds and a binder. The welding apparatus has a vessel filled with exothermic material. When the lead wires are supplied with a high energy electrical current, the lead wires cause the ignition material to ignite in turn causing the exothermic material to ignite. If the coated bridge wire is positioned above the exothermic material, the igniter will broadcast multiple points of ignition over the top of the exothermic material.

A wiring clip for stud frame dry wall construction holds various forms of wiring a required distance from the nearest edge or face of the stud to which the dry wall is secured. A wire form of the clip is particularly suitable for wood studs while strap forms may be used with studs made of metal or wood or other material. Each form of the invention includes an L-shape portion adapted to be secured to the face and/or side of the stud. Extending from such L-shape portion parallel to and recessed from the edge of the stud (interior of the wall board) is a strut and arm with the arm being hinged at the end of the strut remote from the L-shape portion and adapted to be folded back to extend parallel to the strut and locked in place to embrace wiring between such arm and strut. Each form of the clip is easy to install and accommodates a variety of types of wiring. The clips may be crimped by pliers tightly to embrace and conform to the wiring after installation. When properly installed, the wiring will meet code requirements.

Wiring clip

An electronically controlled power supply is adaptable upon throwing a single mode changing switch for shielded metal arc welding (SMAW) and stud welding. The power transformer and control circuitry of a stick welding power supply are, according to the invention, adapted with facility for higher power output, relative to that required for stick welding, for a relatively short timed duration suitable for stud welding. Safety shut down features improve safe use of the power supply, particularly during stud welding, and protect against transformer overload.
