Abstract: 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.

Abstract: 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.

Abstract: 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.
