US Patent:

43309330, May 25, 1982
Filed:

Jul 28, 1980
Appl. No.:

6/172589
Inventors:

Henry W. Bullinger - Wilton CT
Clifford L. Friesel - Redding CT
Assignee:

The Perkin-Elmer Corporation - Norwalk CT
International Classification:

H01C 702
US Classification:

29612
Abstract:

A material holder is fabricated by press-fitting and welding a series of discs into an open cylinder housing. Shrinkage of the cylinder from the welding of the first disc is accommodated by selecting a smaller disc for the second press-fit. A support post is welded to the last disc and shrinkage of that disc from welding of the support post is accommodated by selecting an oversize disc for attachment to the support post. Shrinkage of the last disc also compensates for additional shrinkage of the cylinder from welding of the second disc.

US Patent:

48132675, Mar 21, 1989
Filed:

Mar 5, 1987
Appl. No.:

7/022147
Inventors:

Stanley D. Norem - Bayside NY
Henry W. Bullinger - Wilton CT
Assignee:

The Perkin-Elmer Corporation - Norwalk CT
International Classification:

G01N 3108
US Classification:

73 231
Abstract:

A thermal conductivity cell is described whose elements are well protected against short term temperature fluctuations, changes in flow rates, leaks, and vapor pressures of construction materials. The sample and reference chambers are formed within a relatively large copper block with a controlled thermal time constant. The thermal elements are isolated from the gas flow paths by porous metal plugs which are thermally "clamped" to the block. Element feed-throughs are potted in thermally conductive epoxy to minimize the effect of temperature gradients.
