Abstract: A porcess for producing a foamed synthetic resin body comprising continuously extruding a foamable thermoplastic resin extrudate composition from an extruder die (2, 3) into a reduced pressure zone (11, 19), subjecting the extrudate (F) to en expansion molding step, a cooling-hardening step and a cutting step while transporting the extrudate through the reduced pressure zone to obtain a foamed piece of predetermined length (F min ), shutting off a portion (19) of the reduced pressure zone surrounding the foamed piece from the other portion thereof when the foamed piece has reached a specified position to restore the foamed piece surrounding portion to a normal pressure, subsequently discharging the foamed piece into the atmosphere, and thereafter bringing the surrounding portion into communication with the reduced pressure zone again upon reducing the pressure. Foamed resin bodies of desired expansion ratio and shape can be prepared continuously with high cooling efficiency. An apparatus for practicing the process is also disclosed. Such apparatus includes means to form a continuous length of extrudate with a vacuum chamber and means to cut the extrudate to length and means to pass (10, 10 min ) the cut extrudate into a second chamber (19), and then to cause the cut length to exit the second chamber (11) without affecting the reduced pressure in the chamber or reduced pressure zone.

Granted: 1995-04-18
Abstract: The present invention provides a method and apparatus for establishing point-to-point full duplex communication between two stations served by a local area network (LAN) or connected by a communication link.  One station initially transmits a request message through the link.  The request message indicates that a first station is available for full duplex communication and also serves as a test to determine whether any non-full duplex devices are present along the point-to-point link between the first station and a second station.  A second station receives the request message and responds by transmitting a reply message which indicates its availability for full duplex communication.  Subsequently, full duplex communication may commence.  The two stations periodically exchange additional messages to continuously verify that full duplex communication is operating properly.
