摘要： The present invention provides an improved gas transfer apparatus designed for enhanced purging of a pigtail and a process for effecting such purging. The improvement in the apparatus resides in an integrated system of components comprising: a surge chamber having a first end, a body and a second end, said first end in communication with the pigtail conduit, said body section of said surge chamber having a cross-section larger than the cross-section of said pigtail conduit and a second end in communication with said vessel containing said gas source; and, a purge gas source for delivery of a purge gas to said pigtail conduit whereby during an alternating cycle of pressurization of said pigtail with said purge gas and depressurization, optionally with application of vacuum within said pigtail conduit, impurities can be removed from within the pigtail conduit.

摘要： A mold handling device is provided which is suitable for use in the manufacture of articles molded in a wide variety of shapes and sizes from a plastic material such as polyurethane. First and second mold supports are provided to which mating mold portions are respectively secured. The device comprises means to provide mold opening and mold closing relative linear movements between the two mold supports, and drive means are provided to effect pivotal movement of the two supports about a pivot axis which extends transversely to the linear movement between the mold supports. One of the mold supports is mounted for independent pivotal movement about the same pivot axis whereby the arrangement facilitates access to each mold portion when the mold is open.
