Filed:

Jan 31, 1990

Appl. No.:

7/473218

Inventors:

Robert R. Larson - Redmond WA

Assignee:

Hi-Tech Refrigeration, Inc. - Bothell WA

International Classification:

F25B 4702

US Classification:

62 81

Abstract:

A hot gas defrost type refrigeration system in which refrigerant used to defrost is returned to the system's refrigerant circuit after being collected and reduced in pressure, as by expansion valve means, to a pressure below the pressure in the system's return suction header, then heated as by means involving heat exchange with the system's high pressure refrigerant, the refrigerant used to defrost thus being in a superheated gaseous state and returned to the system's return suction header in such state without risk of introduction of liquid refrigerant to the system's compressor(s).

The Boeing Company - Seattle WA

International Classification:

B64C 126

US Classification:

244 87

Abstract:

An aircraft vertical fin-fuselage structural integration system wherein a plurality of vertical tail fin spars, extending transversely across the fin and fuselage and substantially parallel to the longitudinal axis of the fin, are integrally connected directly to the fuselage pressure bulkhead so as to directly transmit or transfer the vertical fin and horizontal stabilizer empennage loads to the fuselage structural network. The system can be adapted to any type of aircraft, and in the case of an aircraft of the BOEING 727 class, the spars accommodate the air intake S-duct operatively associated with the craft's rear engine housed within the rearwardmost portion of the fuselage. The spars also have their lateral configurations fabricated so as to match the fuselage loft lines.
