Title: Continuous ultrasonic devulcanization of vulcanized elastomers
Inventor: ISAYEV AVRAAM
IPC: C08F2/56
Filed: 1993-06-16
Granted: 2003-08-12
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: Method and apparatus for the solvent extraction of oil from bitumen containing tar sand
Inventor: ROSENBLOOM WILLIAM J
IPC: C10G1/00
Filed: 1995-04-26
Granted: 1996-12-24
Abstract: A method and apparatus for extracting bitumen whereby tar sand containing bitumen components is contacted with a heated thinning oil mixture to reduce the tar sand viscosity and dissolve bitumen to form a lower viscosity feed slurry.  The feed slurry is contacted with a light oil in a separator wherein the mixture is separated into product oil and oil sand. The oil sand is washed with solvent in a countercurrent fashion to extract occluded oil to form the light oil. Washed sand containing solvent is heated above the boiling point of the solvent in a mufti-hearth solvent recovery furnace to vaporize the solvent. The solvent vapors are stripped from the sand by flowing inert gas through the sand in the mufti-hearth solvent recovery furnace. Inert gas containing solvent vapors is directed from the multi-hearth solvent recovery furnace to a heat exchanger/scrubber where the inert gas and solvent vapors are contacted with product oil from the separator. The solvent vapors are absorbed by the product oil to form the heated thinning oil mixture which is contacted with the tar sand. The resulting thinning oil temperature is greater than the product oil due to heat transfer from the solvent vapors and inert gas. Inert gas is recycled from the heat exchanger/scrubber back to the multi-hearth solvent recovery furnace.

Title: Gas, fire and earthquake detector
Inventor: ANDERSON GARRY J
IPC: G01V1/00
Filed: 1996-02-28
Granted: 2001-01-30
Abstract: A safety system for a building has an earthquake detector circuit for detecting ground accelerations exceeding a threshold acceleration/frequency curve dividing safe and hazardous ground accelerations throughout a predetermined frequency range. The earthquake detector includes an accelerometer for measuring linear acceleration along an axis, and for generating an acceleration signal indicative of a magnitude of the measured acceleration. A filter circuit produces a filtered acceleration signal from the acceleration signal. The gain/frequency characteristic of the filter circuit is a reflection of the threshold acceleration/frequency curve, such that ground accelerations falling on the threshold acceleration/frequency curve yield a filtered acceleration signal having a substantially constant value throughout the frequency range. Finally, a threshold circuit compares the filtered acceleration signal to a predetermined threshold voltage, and produces an earthquake detected signal indicative of the comparison result. The safety system can also include a gas detector circuit capable of detecting a gas in air, and generating a gas detected signal in response to detection of the gas. A high temperature detector circuit can also be provided for detecting a high gas temperature, and generating a fire detected signal in response to detection of the high temperature gas. A main unit including a microprocessor is responsive to the earthquake detected signal, gas detected signal and the fire detected signal, and generates a first control signal in response to any one or more of the earthquake detected signal, gas detected signal and the fire detected signal. A valve controller closes a gas valve to shut off a supply of gas in response to the first control signal.

Abstract: For economy of operation, as much as possible of the total length of a steel strip being rolled by a Steckel mill (11) should be maintained at an acceptable high temperature. To this end, the trailing edge of the strip is drawn into the coiler furnace (21 or 23) to the extent possible without losing driving control of the strip. This is enabled by providing within or in close proximity with the entrance/exit port (35) of the coiler furnace (21 or 23) a pair of preferably heated pinch rolls (41 or 43) that drives the trailing edge of the strip into the coiler furnace (21 or 23) as far as possible, leaving only a very short protruding portion of that trailing edge outside the coiler furnace (21 or 23). The strip may be left idle within the coiler furnace (21 or 23) for as long a time as is required to bring the temperature of the wound strip up to a target operating temperature. Then the same pair of pinch rolls in (41 or 43) or near (31 or 33) the entrance/exit port (35) of the coiler furnace (21 or 23) drives the strip out of the coiler furnace (21 or 23) toward the Steckel mill (11).

Abstract: In accordance with the present invention, for noise cancellation, a reference noise signal is input to signal-to-noise (SN) power ratio estimating circuitry via a reference signal input terminal. The SN power ratio estimating circuitry causes its adaptive filter for producing a pseudonoise signal from the reference noise signal to operate. The circuitry detects error signal power and pseudonoise signal power out of the pseudonoise signal and other signals, and then outputs an estimate of an SN power ratio based on the detected power. A first delay circuit is connected to the output terminal of the above circuitry. A comparator compares an estimate of an input to and an estimate of an output from the first delay circuit, and produces greater one of the two estimates as an expanded estimate. A step size output circuit controls, based on the expanded estimate, the step size of a second adaptive filter connected to the reference signal input terminal via a second delay circuit. A subtracter subtracts a pseudonoise signal output from the second adaptive filter from a received signal sequentially delayed by a third and a fourth delay circuit, thereby cancelling a background noise signal component contained in the received signal.
