Abstract: The present invention relates to a method of communicating a speech signal over a communication medium which utilizes what is called VOX (Voice Operated Transmitter) control and a speech signal transmitting unit and a speech signal receiving unit used in the method are disclosed.  The speech signal includes at least one speech-active duration in which an actual speech of the speech signal exists and one silent duration in which no actual speech of said speech signal exists.  At a transmitting side, the speech signal is analyzed for each of successive frames thereof to determine whether each frame is in the speech-active duration, and is coded for each of successive frames thereof to produce a series of successive coded data of the speech signal.  Then, in response to the detection of a speech starting frame of the speech-active duration, the coded data of the speech starting frame is switched to a preamble, and the preamble and the successive coded data subsequent to the speech starting frame are transmitted in the form of a series of successive frames. At a receiving side, the preamble is detected and the decoded results of the coded actual speech data subsequent to the detected preamble as a speech signal are provided.  When a predetermined number of successive coded actual speech data have been detected without having detected a preamble preceding thereto, it is decided that the decoded results of the coded actual speech data are in a speech-active duration and the decoded results are outputted as a speech signal.

Title: Method and apparatus for producing foam with reduced thermal conductivity
Inventor: JASTER HEINZ
IPC: B01F23/30
Filed: 1993-11-25
Abstract: METHOD AND APPARATUS FOR PRODUCING FOAM WITH REDUCED     THERMAL CONDUCTIVITY            Abstract of the Disclosure The thermal conductivity of a foam is lowered by increasing the cell gas concentration of the foam.  A foam extruder having a container for feeding polymer pellets to the extruder and an injector for injecting a blowing agent into the extruder is provided with an inlet port for injecting a high molecular weight gas into the container.  The injection of the high molecular weight gas purges air from the container, thereby preventing air from being ingested by the extruder with the polymer pellets. This results in a higher cell gas concentration which lowers the thermal conductivity of the foam.  The high molecular weight gas is preferably selected from the group including chlorofluorocarbons, hydrofluoro-carbons, xenon, and perfluorinated fluorocarbons.

Title: Sliding Gate Terminal Unit for Air Handling System
Inventor: COTE ANTHONY
IPC: F24F13/12
Filed: 1993-12-08
Abstract: A terminal unit for an air handling system and comprised of a housing having a conditioned air inlet for receiving forced conditioned air in the housing.  A main outlet opening and a by-pass air outlet opening are provided in the housing.   An air flow path is defined between the air inlet and the outlet openings. An   air  divider  gate   is   slidingly  displaceable transverse to the air flow path to deflect air entering the inlet to one or both of the outlet openings.   The divider gate has an outlet obstructing rear end and an upstream  deflecting  face.    A  linkage  assembly  is connected to the divider gate to displace the gate across the flow path to simultaneously open one of the outlet  openings  and  close  the  other,   in  equal proportions,   as   desired,   while   maintaining   a substantially constant total  outlet opening  area  as well as maintaining substantially constant inlet air flow  conditions.    An  actuator  device,  such  as  an electric motor or a pneumatic system, is connected to the  linkage  to  effectuate  the  displacement  of  the divider  gate.    The  force  required  to  displace  the divider   gate   by   the   actuator   device   remains substantially constant throughout the displacement of the  gate  during  operating  conditions  of  the  air handling system.
