A resistor assembly and method of assembling a resistor to a coupling, comprises providing a resistor having a first end and a second end, the resistor being tubular in shape and providing a coupling housing having an open end for receiving the first end of the resistor, the coupling housing including a sealing member, a retainer, and a support washer. The retainer is interposed between the support washer and sealing member. The first end of the resistor is inserted into the open end of the coupling housing. The tube is rotated within the coupling housing so that the resistor is in sealing engagement with the sealing member and retained by retaining member.

Quick connect fittings

A resistor apparatus for containing broken pieces of an overheated resistor body is provided. The resistor apparatus includes a resistor body and a first and second lead wire electrically connected to opposite sides of the core. A gas permeable containment casing substantially encloses the resistor body and is fixed to the lead wires by fasteners, therefore maintaining the containment casing in a position substantially enclosing the resistor body. In the event that the resistor overheats and the resistor body breaks, the containment casing is maintained in a position to contain any pieces of the overheated resistor that break away, while allowing any gasses to escape, therefore preventing explosion of the containment casing and damage to surrounding apparatuses.

Gas permeable resistor casing

A method for bonding an electrically conductive silicon carbide structure to an electrically conductive siliconized silicon carbide structure by temporarily securing the siliconized silicon carbide structure to the silicon carbide structure; placing the silicon carbide structure with secured siliconized silicon carbide structure into an induction heating furnace having an induction coil which heats electrically conductive material in the furnace when sufficient electrical power at a frequency of from about 300 to about 1000 KC is passed through the coil; and causing sufficient electrical power at a frequency of from about 300 to about 1000 KC to be passed through the coil to raise the temperature of the siliconized silicon carbide structure and silicon carbide structure to a temperature above about 1500&#xb0; C. at the region of temporary attachment to release the attachment and cause silicon metal to flow from the siliconized silicon carbide structure into the silicon carbide structure to form a siliconized silicon carbide bond between the silicon carbide structure and siliconized silicon carbide structure.
