Environmentally Controlled Induction Heating System For Heat Treating Metal Billets
US Patent:
6289033, Sep 11, 2001
Filed:
Dec 8, 1998
Appl. No.:
9/206332
Inventors:
Bryan P. Tipton - Johnstown PA
Russell S. Corrente - Portage PA
Chris C. Alexion - Baltimore MD
Mark C. Waterbury - Johnstown PA

Assignee:
Concurrent Technologies Corporation - Johnstown PA
International Classification:
H05B 1100
US Classification:
373 7
Abstract:
An environmentally controlled heating system for heating metal alloy billets wherein a trolley system carries the billets through the chambers of the induction heating system in crucibles that are pushed or pulled by actuators. The billets enter the system through a load-chamber and travel through a main chamber to a heating area where the loaded crucibles pass through a series of induction heating coils. The heated billets leave the heating area through a dump-chamber where they are delivered to a forming system. The empty crucibles reenter the main chamber and travel back to the loading area to receive another billet. The heating system is controlled through a computing device for monitoring and controlling the system, preferably a programmable logic controller. A vacuum system evacuates air from the chambers, and an inert gas system back-fills the chambers with an inert gas. A gettering system continually cleans the inert gas.
Method And Apparatus For Venting And Purging Of A Fuel Cell
US Patent:
7132181, Nov 7, 2006
Filed:
Aug 8, 2003
Appl. No.:
10/637832

Assignee:
General Motors Corporation - Detroit MI
International Classification:
H01M 8/04
US Classification:
429 13, 429 22
Abstract:
Hydrogen in a fuel cell is vented and purged with a fail-closed valve using stored energy (e. g. from a capacitor) when a diagnostic parameter is outside of an acceptable operating range. The valve closes after the stored energy has depleted. A safety switch in the relay circuit of the solenoid switch (or solenoid valve) is also grounded in computer-implemented shutdowns. Benefits from the invention include use of air-compatible catalysts, minimized parasitic losses to power output, minimized contamination of fuel cell internal surfaces after venting, minimized risk of explosive mixture buildup, and efficient operation.
