Title: Membrane air dryer with scheme to reduce air lost as sweep air
Inventor: CUNKELMAN BRIAN L
IPC: B01D53/26
Filed: 1999-01-20
Granted: 2002-08-13
Abstract: A control system reduces the amount of gas lost as sweep gas from a membrane gas dryer. The membrane gas dryer is of the type that features an inlet end that receives moisture laden gas from a compressor, an outlet end from which dried gas is discharged to a pneumatic component and a drain port from which permeate sweep gas inclusive of permeate water vapor is expelled from the gas dryer. The control system includes a purge valve that is connected to the drain port of the gas dryer and a mechanism that controls the purge valve. The purge valve has a pilot port that responds to pressure by closing the purge valve thereby preventing the permeate sweep gas from exhausting to atmosphere through the drain port. The mechanism controls the purge valve such that (i) when the compressor is unloaded, the mechanism allows flow of the dried gas from the pneumatic component to pressurize the pilot port thereby closing the purge valve and preventing the permeate sweep gas from exhausting to atmosphere and (ii) when the compressor is loaded, the mechanism vents the pilot port to atmosphere thereby opening the purge valve and allowing the permeate sweep gas to exhaust to atmosphere via the drain port of the membrane gas dryer.

The rollers are rotatably engaged on a distal frame portion (26) which has a pair of roller engaging portions (30, 32). The roller engaging portions are separated from each other via a V-shaped medial frame section (40). The medial frame section defines a receiver which permits the reception of a paint tray divider. The paint tray divider separates two receptacle portions of a paint tray. A frame for the bifurcated roller (12) includes an intermediate frame portion (34) leading from a handle (28) to one of the roller engaging portions (30) of the distal frame portion (26). The other of the roller engaging portions (32) includes a free outer end and it is over this end that roller covers (60,62) are slid off the roller mounts and other roller covers slide onto their respective roller mounts. The roller cover which engages the roller mount proximate to the intermediate frame portion (34) slides over the medial frame portion (40) and onto and off the other of the roller mount when it is to be replaced or cleaned. The intermediate frame portion (34) and roller engaging portions define sections of a rod such that the frame (12) for the bifurcated roller (10) is integral and one-piece.

Abstract: A method for sterilizing the interior of the lumen, where a dry booster which does not contain liquid and which has a volume at least 2 times the volume of the lumen is attached to the end of the lumen. The lumen and dry booster are placed in a sterilization chamber, and germicide is introduced into the chamber. A higher pressure is created outside the booster than inside the booster. The empty dry booster draws germicide into the lumen, sterilizing the interior of the lumen. The method can be enhanced by reducing the pressure in the chamber before introducing the germicide.

Title: Vacuum dry sprinkler system containing a sprinkler head with expulsion assembly
Inventor: FRANSON SCOTT T
IPC: A62C35/62
Filed: 2001-10-10
Granted: 2009-09-29
Abstract: A vacuum dry sprinkler system includes a sprinkler head formed with a body having a central orifice through which fire extinguishing fluid is expelled through an outlet end. A yoke, attached to the exterior surface of the sprinkler body, extends beyond the outlet end of the sprinkler body and is connected at its apex to a deflector. A thermally sensitive trigger member is coupled to the yoke and the outlet end of the sprinkler head. The sprinkler body carries an expulsion assembly which includes an expulsion member and a thrust member. In response to a fire, the expulsion member of the expulsion assembly overcomes the vacuum force and expels the sealing assembly out of the outlet end of the sprinkler body, while the thrust member laterally thrusts the sealing member out of the water trajectory path, and thus, prevents the sealing assembly from reseating on the outlet of the sprinkler head.
