US Patent:
5121903, Jun 16, 1992
Filed:
Mar 11, 1991
Appl. No.:
7/667332
Inventors:
Fred W. Ripley - Perkasie PA
David E. Felker - Allentown PA
David E. Felker - Allentown PA
Assignee:

International Classification:

US Classification:

Abstract:
The present arrangement provides for having the plenum divided into at least two sections. One section dumps quench gas from a first direction into the hot zone chamber during a first period and the other section dumps quench gas into the hot zone from an opposite direction during a second period whereby the cooling is relatively uniform. During the quenching operation the quenching gas is drawn from the hot zone chamber through a heat exchange and is returned therefrom to a loop through the hot zone chamber in touch with the workpiece. Direction flow gates control the alternate use of the two plenum.
