  • Patent number: 6070440
    Abstract: An apparatus for opening and closing a door of a pressure cleaning vessel for a dry cleaning system which requires minimal clearance to operate is provided. The apparatus includes a frame slidably attached to the cleaning vessel and having a base member with a pair of attached upstanding side arms which carry the door of the cleaning vessel. The apparatus further includes a first horizontal actuator carried by the cleaning vessel and operatively connected to the frame for moving the frame in a substantially horizontal direction relative to the cleaning vessel such that the door of the cleaning vessel moves between a closed position and an intermediate position wherein the door is substantially in front of the cleaning vessel. A second vertical actuator carried by at least one of the side arms and operatively connected to the door moves the door in a substantially vertical direction relative to the cleaning vessel and the frame between the intermediate position and an open position.

  • Patent number: 5850747
    Abstract: A liquified gas dry-cleaning system including a storage tank containing a liquified gas derived from a liquifiable gas, a pressure vessel for containing a liquid bath derived from the liquifiable gas, and a circulating system for transporting the liquified gas between the storage tank and the pressurized vessel. The pressurized vessel includes a compressor mounted in a wall structure of the vessel for use in evacuating a gaseous form of the liquifiable gas released from the liquid bath during a cleaning cycle. Positioning of the compressor in this manner allows heat generated during each compression stroke of the compressor to be directed to the interior of pressure vessel to minimize the effects of a temperature decrease incident to the gaseous evacuation.
