    摘要: Prefabricated insulated pipe sections are constructed of an inner pipe surrounded by a concentrically-positioned outer pipe. End portions of the inner and outer pipes are joined with bellow members so that an annular space is defined. A portion of the inner pipe is wrapped with layers of insulation material with inert insulating granules positioned between the layers. The annular space is partially evacuated to below atmospheric pressure. Multiple pipe sections may be joined by their inner pipes through brazing or other known methods. The joints and neighboring bellow members on abutting pipe sections are covered by clam shells that are sealed and filled with insulation.

    摘要: A method for removing contaminants from synthetic resin material includes contacting a particulate synthetic resin material containing at least one contaminant with a solvent other than carbon dioxide. At least a portion of the contaminant is removed from the particulate synthetic resin material and becomes dispersed in the solvent. The solvent, with the contaminant dispersed therein, is then removed from the particulate synthetic resin material. Thereafter, at least a portion of the solvent still contained on the synthetic resin material is removed by contacting the particulate synthetic resin material with liquid carbon dioxide to dissolve the solvent into the carbon dioxide.

    摘要: A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks in communication with a compressor. A sealed cleaning chamber contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still. The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber. The still may be positioned within the storage tank and partially surrounded with a shroud for efficient heating of the still with gas from the cleaning chamber. During agitation, liquid solvent from the cleaning chamber may be heated and filtered.

    摘要: A high pressure chamber opening is equipped with a cylindrical element that features a circumferential flange. The circumferential flange features concentrically positioned primary and secondary O-ring seals that surround the chamber opening. A door is clamped to the circumferential flange and over the opening and the circumferential seals. As a result, the opening is sealed and an annular passage is formed between the seals. A port is formed in the cylindrical element so that the annular passage may communicate with a pressure switch. The port also communicates with a relief valve. The pressure switch signals the system operator when the pressure in the annular passage rises due to failure of the primary O-ring. The relief valve vents the annular passage when the pressure therein increases to a level where damage to the secondary O-ring could occur. The relief valve setting is such that the pressure within the annular passage may rise to a level where dry ice formation is prevented.

A sealed cleaning chamber contains the objects being dry cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber through cleaning nozzles so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. A still is disposed within one of the storage tanks and receives soiled liquid carbon dioxide as it is returned from the chamber. The pressure in the storage tank causes the soiled liquid carbon dioxide in the still to boil off. The gas is communicated to a third tank.
