Abstract: A hermetically sealed fixed film resistor including a coupling element of soft alloy material between the resistive element and the leads for providing strain relief. The resistive element is composed of a resistive film having coated ends composed of a refractory metallic material for providing reliable electrical and mechanical connection to the coupling element.

Abstract: A mounting system for an infrared tube or the like. The tube is supported by threaded bolts which axially extend from insulator plugs at each end of the tube. The tube is mounted by inserting one of the bolts into a bore in a mount until the insulator at the end of the tube contacts the inner surface of the mount. The bolt at the other end of the tube is then placed in axial alignment with a bore in another mount and inserted therethrough. The diameter of the bolts is substantially smaller than the diameter of the bores. A cylindrical sleeve having an internal diameter slightly larger than the diameter of the bolts and an external diameter slightly smaller than the diameter of the bores is inserted through each aperture to frictionally engage the bolts with their internal surfaces and the mounts with their outer surfaces. Electrical conductors are then secured to each bolt to supply electrical power to the tube.
