Patent CA-2136533-A1 (CA)
Inventor: DEGREGORIA ANTHONY J
IPC: F25B21/00
Filed: 1993-06-02
Abstract: In an active magnetic regenerator apparatus having a regenerator bed of material exhibiting the magnetocaloric effect, flow of heat transfer fluid through the bed is unbalanced, so that more fluid flows through the bed from the hot side of the bed to the cold side than from the cold side to the hot side.  The excess heat transfer fluid is diverted back to the hot side of the bed.  The diverted fluid may be passed through a heat exchanger to draw heat from a fluid to be cooled.  The apparatus may be operated at cryogenic temperatures, and the heat transfer fluid may be helium gas and the fluid to be cooled may be hydrogen gas, which is liquified by the device.  The apparatus can be formed in multiple stages to allow a greater span of cooling temperatures than a single stage, and each stage may be comprised of two bed parts.  Where two bed parts are employed in each stage, a portion of the fluid passing from the hot side to the cold side of a first bed part which does not have a magnetic field applied thereto is diverted back to the cold side of the other bed part in the stage, where it is passed through to the hot side.  The remainder of the fluid from the cold side of the bed part of the first stage is passed to the hot side of the bed part of the second stage.  The fluid flowing from the cold side of a bed part of the second stage is partly passed to the cold side of the second bed part of the second stage and partly diverted back to the hot side of the first stage through a heat exchanger which draws heat from a fluid to be cooled.

Title: Continuous ultrasonic devulcanization of vulcanized elastomers
Inventor: ISAYEV AVRAAM
IPC: C08F2/56
Filed: 1993-06-16
Abstract: This invention relates to a continuous ultrasonic method and apparatus for breaking the carbon-sulfur (C-S), sulfur-sulfur (S-S), and if desired, carbon-carbon (C-C) bonds in a vulcanized elastomer. It is well known that vulcanized elastomers having a three-dimensional chemical network, cannot flow under the effect of heat and/or pressure. This creates a huge problem in the re-cycling of used tires and other elastomeric products. Through the application of certain levels of ultrasonic amplitudes in the presence of pressure and optionally heat, the three-dimensional network of vulcanized elastomer can be broken down. As a most desirable consequence, ultrasonically treated cured rubber becomes soft, thereby enabling this material to be reprocessed and shaped in a manner similar to that employed with uncured elastomers. The apparatus relates to the ultrasonic reactor (20) (e.g. an extruder). The reactor (20) is connected to an ultrasonic die assembly (10);  the die assembly (10) consists of a transducer portion (12), which includes a power converter (14) and booster (13), connected to a horn portion (15), the assembly being supported by mounting bracket (18), and being attached to the reactor (20) through an adaptor portion (19). The reactor (20) includes a barrel (22), fed through hopper (24), the screw (26) within the barrel portion being driven by a drive (25), energized by a motor (28) (not shown). The horn portion (15) includes a die portion (16) through which the devulcanized elastomer being extruded is forced at a pressure shown by a pressure gauge (21). The ultrasonic generator (10) of the ultrasonic die of the invention, movably attached by mounting bracket (18) through adaptor legs (19) to a reactor (20). The reactor (20) is surrounded by a heating jacket (42). Vulcan-ized material is fed into die (16) through reactor bore exit (36) of exit bore diameter (dr) and into die inlet bore (38) of diameter (di). The vulcanized material is moved under pressure toward die exit bore (37) and leaves through die inlet bore (38).

Title: Pulse width modulation for spatial light modulator with split reset addressing
Inventor: DOHERTY DONALD B
IPC: G09G3/18
Filed: 1995-05-19
Abstract: A method of implementing pulse-width modulated image display systems  (10, 20) with a spatial light modulator (SLM) (15) configured for split-reset addressing.  Display frame periods are divided into time slices.  Each frame of data is divided into bit-planes, each bit-plane having one bit of data for each pixel element and representing a bit weight of the intensity value to be displayed by that pixel element.  Each bit-plane has a display time corresponding to a number of time slices, with bit-planes of higher bit weights being displayed for more time slices.   The bit-planes are further formatted into reset groups, each reset group corresponding to a reset group of the SLM (15).  The display times for reset groups of more significant bits are segmented so that the data can be displayed in segments rather  than  for  a  continuous  time.    During  loading, segments of corresponding bit-planes are temporally aligned from one reset group to the next.  The display times for less significant bits are not segmented but are temporally aligned to the extent possible without loading conflicts.
