Furnace assembly for thermal analysis use

Claim 1

A furnace and sample insertion assembly for use under high vacuum conditions, comprising first tubular means, a first disc having a central bore which is at least as large as the inner diameter of said first tubular means, said first disc being disposed perpendicularly with respect to said first tubular means and secured thereto an array of rodlike heating elements electrically coupled and disposed perpendicularly with respect to said first disc and secured adjacent to the outer periphery of said first disc, a second disc, said second disc being disposed above said first disc and electrically and mechanically coupled to said heating elements, a second tubular element, said second tubular element being axially aligned with a flanged mounting plate, said flanged plate extending transversely from said tubular element means intermediate the ends thereof, said flanged plate being hermetically sealed to said tubular element means, said tubular means having a valve therein on the side of said flanged plate remote from said rodlike heating elements, 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 rodlike heating elements, means for sealing the tubing means to said cell assembly, and lead means for energizing said heater winding.
