US Patent:

6104010, Aug 15, 2000

Filed:

Oct 19, 1998

Appl. No.:

9/174859

Inventors:

David L. Reichle - Littleton CO
William P. Washington - Irving TX

Assignee:

Fastrax Industries, Inc. - Englewood CO

International Classification:

H05B 306

US Classification:

219537

Abstract:

A high efficiency, direct conduction track switch heater (24) and associated spring clamp (70) are disclosed. The heater (24) includes a generally blade-shaped jacket (30) dimensioned for mounting on the gauge side 26 of a fixed rail (16) at the track switch interface. The jacket dimensions reduce the likelihood of impact damage due to track switching while providing an enlarged heat transfer surface (66). The spring clamp (70) presses the heater (24) tightly against the rail (16) while accommodating normal thermal expansions and providing a narrow profile for the overall heater and clamp assembly.

William E. Washington - Denver CO

International Classification:

B60T 1700

US Classification:

303 69

Abstract:

This invention relates to release/relief valves, trailer brake release valve, and apparatus for equalizing pressure and absorbing shock, as they pertain to pneumatic brake systems for buses, trucks, and trucks/semi-trailers, singular and in multiple combinations in automotive air brake installations; and more particularly to a differential pressure regulator quick release valve that employs a dilivery channel for directing and centralizing fluid pressure differentials to its base housing and the same delivery channel directing the exhaust of fluid pressure to its quick release ports.
