Abstract: A flexible, substantially lamellar silicone foam rubber-based heater for heating fluid lines such as high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses a flexible, oblong substantially longitudinally uniform heater body including an oblong block of a thermally conductive, resiliently compressible material for conforming the heater to a line of complexly shaped components connected in series. The block can be supported by a silicone rubber support layer in contact with a flexible heater element containing layer, and an outer silicone foam rubber insulation layer. Fasteners, such as separatable retaining bands spaced along the line can hold the heater in place. A matable pair of bodies, or a single folded body can enwrap the line.

Abstract: An electronic module housing having a rounded stylized dog-bone-type shape and an equatorial partial light bar. The shape provides a view of parts of the light bar from many locations. The controller circuitry can detect a malfunction among one or more of a plurality of current-drawing components by detecting that the total cumulative current drawing by all the components falls outside a predetermined nominal range.

Abstract: A semi-flexible laminar silicone foam rubber-base heater for high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses superimposed adhesively bonded layers of an etched foil heater element containing layer, a high-to-low heat thermal transition layer, a thermal fuse laden silicone foam rubber insulation layer and a durable wrapping layer. The system can provide for the combined use of highly controllable etched foil heater elements, clean silicone foam rubber insulation, and inexpensive mechanical thermal fuses safely in a high heat gas supply and exhaust line environment.

Abstract: A moisture-sealing and thermally-isolating miniature implement for terminating a mineral-insulated and metal-sheathed cable and connecting it to a power source, includes a hollow contact prong protruding from one axial end of a metallic heat-sink barrel penetrated from an opposite end by the steel sheath of a heating element cable. The heating element contacts a nickel or nickel clad iron pin that penetrates the prong and is welded to its most distal extremity. The sheath is welded to the proximal end of the barrel by a hermetic brazed joint, and the distal end of the barrel is hermetically plugged around the prong by a metalized alumina ceramic seal. The copper pin is connected to the end of the heating element within the sheath and mineral insulation. The barrel is machined to have a series of deep peripheral grooves that act as thermal conductivity reducing chokes.
