Patent CA-2370932-C (CA)
Inventor: KALINOSKY JOSEPH

Filed: 2000-04-14
Granted: 2007-06-26
Abstract: A mechanism (1) for selectively securing a cover (14) to a flange (12) of a pressure vessel. A plurality of such devices can be employed, using a plurality of studs (10) that extend through matching openings in the flange (12) and cover (14). A movable anchor plate (18) or plates, also with holes (20) through which each stud (10) extends, is disposed adjacent to the flang e (12) or cover (14). The head of each stud (10) will fit through its associat ed hole (20) of the anchor plate (18) (and into the opening of the closer one o f the flange (12) or cover (14)) only if the anchor plate (18) is properly oriented. When the anchor plate (10) is so oriented, a piston head (10a) at the opposite end of the stud (10) can be actuated away from the flange (12) and cover (14) to retract the stud head (42) into the opening (20) of the flange (12) or cover (14). This protects the stud (10) when the cover is disengaged from the flange (12). The stud (10) can be biased in the opposite direction to permit the anchor plate (18) to be reoriented into a position i n which the stud head (42) cannot pass through the anchor plate (18), so the stud (10) can clamp the flange (12) and cover (14) together.

Title: Cleaning system utilizing an organic cleaning solvent and a pressurized fluid solvent
Inventor: DAMASO GENE R
IPC: B08B7/00
Filed: 2000-10-13
Granted: 2004-03-30
Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum. Finally, the drum is de-pressurized to atmospheric pressure to evaporate any remaining pressurized fluid solvent, yielding clean, solvent free textiles. The organic solvent is preferably dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether or tripropylene glycol methyl ether, a mixture thereof, or a similar solvent and the pressurized fluid solvent is preferably densified carbon dioxide.
