Patent CA-2197361-A1 (CA)
Inventor: DREIMAN NELIK I
IPC: F25B31/00
Filed: 1997-02-12
Abstract: A hermetically sealed reciprocating refrigeration compressor includes a housing, a motor, and a compressor mechanism having a crankcase.  A suction inlet connector includes a conduit sealingly connecting a refrigerant suction line to a suction inlet opening in the crankcase for communicating suction gas to a cylinder.  The suction inlet connector includes a spring-energized seal to sealingly couple the connector to a suction inlet fitting integral to the housing and to the suction inlet opening in the crankcase. Misalignment of the compressor mechanism relative to the housing is compensated by the suction inlet connector, which can pivot in multi-angle directions as needed during compressor operation. Stress on the suction inlet connector is greatly reduced, resulting in reduced vibrations and noise and fewer incidents of connector failure.  During compressor operation, discharge gas is introduced into a discharge plenum provided in the crankcase. The spinning rotor imparts a spinning vortex tube effect on the discharge gas in the discharge plenum.  The vortex tube effect causes a cooler flow path of fluid to flow through a gap formed between the rotor and the stator of the motor, thereby effectively cooling the motor.

Title: Exhaust arrangements for powder spray booth
Inventor: JOSEFSSON LEIF E
IPC: B05B15/12
Filed: 1995-09-21
Abstract: A paint spray booth (301) utilizes an exhaust system (302a, 302b) extending longitudinally along the path of the articles (312) to be painted having an adjustment mechanism (336; 536; 836) for varying the width of the exhaust inlets (304a,b; 504; 804) extending longitudinally for substantially the entire length of the air exhaust element and a downwardly slanting bottom surface (324) of the exhaust elements for yielding powder overspray of uniform density to a filter media. Adjusting the width of the longitudinally extending exhaust inlet (304a,b; 504; 804) spreads an adjustable pressure drop over the slot opening. Adjusting the velocity of air flow through the exhaust elements substantially avoids powder paint build-up at the exhaust inlet. The slanted configuration of the exhaust elements (302a, 302b), in conjunction with the adjustment mechanism, improves uniformity of filter life by providing a substantially even distribution of powder overspray to a filter media. The invention finds particular advantage in powder spray booth applications and is adapted to modularization thereby enabling retrofitting of existing spray booths with apparatus arranged in accordance with the principles of the invention.
