摘要： A liquified gas dry-cleaning machine having a cleaning vessel with a chamber for containing a wash bath and items to be cleaned, a removable door for sealing the cleaning chamber during a dry-cleaning operation, and a locking ring for retaining the door in closed position. A door opening and closing apparatus is provided which includes a pivot frame for moving the door in an arced path of movement into and out of closed position with the cleaning vessel. The door and locking ring have respective locking lugs with a specifically designed geometry for enabling arced movement of the door into and out of the closed position and for centering the door in aligned relation to the cleaning chamber as an incident to such movement. The locking lugs further have mating locking surfaces designed for point contact in a manner that minimizes stress concentrations at n the roots of the locking ring lugs.

摘要： A pressure vessel for receiving and storing pressurized fluid in a pressurized dense phase liquid dry cleaning apparatus is provided. The dry cleaning apparatus generally includes a cleaning vessel within which garments or the like are cleaned and a solvent recovery device which takes the contaminated cleaning fluid from the cleaning vessel and separates out the contaminants. The pressure vessel comprises a plurality of interconnected hollow structures and as such is substantially self-supporting and occupies less space within dry cleaning apparatus. The pressure vessel can also serve as the support structure for the other components of the dry cleaning system to provide a further cost and space savings.

摘要： A bearing system for mounting a rotating shaft includes a bearing assembly and a bearing mounting structure. The bearing assembly has an inner race which contacts the rotating shaft, an outer race, and bearing elements positioned therebetween. The outer race has an exterior surface with an outer dimension. The bearing mounting structure has a region for affixing it to an external structure in which the bearing system is to function. An internal surface of the bearing mounting structure defines a bearing cavity in which the bearing assembly is to be disposed. The internal surface engages the exterior surface of the outer race. The retention force exerted by the internal surface on the outer surface is determined by the design of the inner surface of the bearing mounting structure that defines the bearing cavity. The internal surface has cut-outs, or scallops, extending axially (with respect to the shaft) along the internal surface. Furthermore, the internal surface is slightly pre-angled inwardly toward the shaft prior to the installation of the bearing assembly. As the installation of the bearing assembly occurs, the internal surface flexes outwardly as the spring action due to the pre-angle provides the requisite retention force. The amount of retention force for a given material with a known thickness depends on the geometry of the cut-outs on the internal surface and the pre-angle. Because the retention force associated with the spring action is a function of known variables, a bearing mounting structure can be designed for a specific retention force by selecting the variables to produce the retention force.

摘要： A liquified gas dry-cleaning system having a pressure vessel for containing a liquid wash bath and a perforated basket rotatably supported within the pressure vessel for containing items during cleaning. For enhancing cleaning and the removal of solid particulate matter on the items to be cleaned, the basket has a plurality of radial mixing baffles fixed to the periphery of the rotary basket and a plurality of gas jet manifolds fixed to the baffles which are operable for directing pressurized jet streams of liquified gas into the basket for agitating the contained items and wash bath simultaneously with physical agitation by the mixing baffles. The dry-cleaning system has a successively operated air purge cycle prior to a dry cleaning cycle, which includes sealing the pressure chamber, introducing a gaseous form of the liquified gas which makes up the wash bath, rotating the basket so that items contained therein are turned and flexed to release at least a portion of any contained air therein, and venting the introduced gas and released air from the pressure vessel.

摘要： A liquified gas dry-cleaning machine having a cleaning vessel with a chamber for containing a wash bath and items to be cleaned and a removable door for sealing the cleaning chamber during a dry-cleaning operation. The dry-cleaning machine has a door opening and closing apparatus which includes a pivot frame for moving the door outwardly from the cleaning vessel in an arced path of movement, and a slide for lowering the door on the pivot frame in a linear path of movement to a position below the level of the cleaning vessel. Reverse movement of the pivot frame thereupon positions the door in a tucked stored position at the same axial location with respect to the cleaning vessel as when the door is closed so as not to impede access to the cleaning chamber nor increase the axial reach of an operator necessary for removing items from the chamber. The door opening and closing apparatus further includes a protective plate which is carried by the pivot frame and is movable between a raised position for protecting operating personnel during door opening and closing operations and a lower position for permitting access to the cleaning chamber following a door opening operation.

摘要： A method and apparatus for spinning and draining an automatic clothes washer after a wash or rinse cycle. After the water is pumped down, the spin drive and drain pump are activated with an on and off schedule of increasing on times, but constant off times. For example, the spin drive and drain pump may be activated for on times of 10, 15, 20, etc. with interleaved off times of 5 seconds. The off times of the drain pump allow suds in the drain pump to be purged, and thereby increase the steady state flow rate of the drain pump.
