ABSTRACT:
The present invention employs a heating element means which is formed into an endless configuration, i.e., a closed plane, circular configuration, loop, etc. In a preferred embodiment the heating element means comprises a molybdenum strip although a plurality of molybdenum sections, which are secured to one another to make up a continuous sectionalized strip could be used. When such a strip conducts electrical current there is heat generated (I.sup.2 R) and such heated strips are the source of heat for the hot zone chamber of a vacuum furnace. There are a number of such continuous strips which make up the overall heating element means for a hot zone chamber. The continuous strips, or heating elements, each has first and second terminal means secured thereto at respectively first and second different locations, so that between said first and second terminals there exist two separated electrical current paths, or a bifurcated path. The first and second terminals are adapted to be connected to an electrical current power source or in series, whereby when electrical current is provided by an electrical current supply source, the current divides as it passes through the bifurcated path (and heat is generated around the entire closed panel) and said current is joined at the second terminal to be returned to the electrical current supply.
