Furnace assembly for thermal analysis use

Claim 1

A furnace and sample insertion assembly for use under highvacuum conditions, comprising tubular means, an annular element having a central bore and which is at least as large as the inner diameter of said tubular means, said annular element being disposed perpendicularly with respect to the longitudinal axis of said tubular means and secured thereto, an array of rodlike support elements disposed perpendicularly with respect to said annular element and secured adjacent to the outer periphery of said annular element, a disc, said disc being disposed above said annular element and coupled to said support elements, a heater winding, said heater winding being disposed around said support elements between said annular element and said disc, a hollow cylindrically shaped heat reflector, said heat reflector surrounding said support elements between said annular element and said disc, a tubular element, the longitudinal axis of said tubular element being aligned perpendicularly with respect to a flanged mounting plate, said flanged plate extending transversely from said tubular element intermediate the ends thereof, said flanged plate being hermetically sealed to said tubular element, said tubular element having a valve therein on the side of said flanged plate remote from said heater winding, said tubular element having an inner diameter which is slightly larger than the diameter of a thermal analysis cell assembly adapted to be inserted therethrough and into the space within said heater winding, means for sealing said tubular element to said cell assembly, and lead means for energizing said heater winding.
