Inventor: SUEHIRO MITSUGI
IPC: C10J3/72
Filed: 1991-10-07
Abstract: A process for purifying high-temperature reducing gases containing sulfureous contaminants including hydrogen sulfide and carbonyl sulfide with an absorbent, said process characterized in that at least three reactor towers which are filled with an absorbent are used, and said process comprises the three steps of absorption, regeneration, and reduction, and during in a part of operation two reactor towers are connected in series so as to carry out regeneration, and O2 concentration can be controlled separately for each regenerating reactor tower in the regeneration step, and steam can be supplied so as to prevent excessive reduction of the absorbent from occurring in the reduction step. The life of the absorbent can be extended and operational costs may be reduced. <IMAGE>
Patent CA-2055315-A1 (CA)
Inventor: COOPER ROBERT W
IPC: G06F13/40
Filed: 1991-11-12
Abstract: A system and method are described which provide for fast sequential access of stored data, as required, for example, in the performance of multiply/accumulate operations in neural network calculations and other sequential computations.  The system includes a video dynamic random access memory (VRAM) with a shift register, a digital signal processor (DSP), and a data/address/control bus for coupling the DSP and VRAM.  The VRAM has a parallel access port and a serial access port, and the DSP has a first input-output (I/O) port and a second I/O port.  The second I/O port of the DSP is coupled, via the bus, to the parallel- and serial-access ports of the VRAM. In response to data applied via the first I/O port, the DSP transfers the applied data, via the second I/O port, the data bus, and the parallel (or serial) access port, to the VRAM for storage.  The stored data is then accessed (by the DSP) as a serial sequence via the serial access port.  The method employed by the system in providing such access includes the steps of transferring the stored data in parallel to the shift register, and outputting the data as a synchronized (clocked) serial sequence from the shift register.

Title: High capacity coconut shell char for carbon molecular sieves
Inventor: FARRIS THOMAS S
IPC: C01B31/08
Filed: 1992-01-16
Abstract: ABSTRACT      A coconut shell char having a high oxygen volumetric capacity is provided by crushing and sizing coconut shells to form granules which are then heated in flowing inert gas at a temperature ramp rate of about 2 to 12°C per minute to a peak temperature of 775 to 900°C which is then held so that the total heating time is up to 8 hours and thereafter the granular char is cooled in an inert gas atmosphere.  The granular char thus produced is oxygen selective in air separation without further modification to narrow the openings of its micropores and has an oxygen volumetric capacity in excess of 8.0 cc/cc.  Further modification of this char is provided by contacting it with an oxidizing atmosphere of carbon dioxide or a mixture of inert gas and carbon dioxide, H20 or 02 at temperatures ranging from 650 to 900°C until the gasified char has been altered so that its volumetric oxygen capacity is greater than 9.0 cc/cc.  The coconut shell char can be further modified directly as prepared or following a gasification procedure by treatment with volatile carbon-containing organic compound which is pyrolyzed to form carbon which reduces the effective pore openings of the original or gasified char.

Abstract: An output level control circuit for radio-frequency transmitter which intermittently transmits radio-frequency carrier waves such as seen in the TDMA radio communication system and the digital cellular mobile telephone system.          The variable gain amplifier unit of this transmitter amplifies the transmitting signal to a predetermined output power level in response to a control signal, the output power level is detected by a detecting diode which receives the application of a temperature-compensated bias voltage, and the sum of the detected output and the bias voltage becomes the detection output to the control loop.  The bias voltage of the detecting diode is stored by bias voltage detection means during the off-period of the transmitting signal, an input reference voltage that is supplied in synchronism with the turning-on of the transmitting signal and the stored bias voltage are added by reference signal addition means, and the added output is served as the reference voltage that corresponds to the predetermined output power level.  Power control means generates the control signal in response to the added output and the detection output, and the control signal controls the output power level of the variable gain amplifier unit.

Title: Improved fuel vaporizer
Inventor: ROBINSON EDGAR C
IPC: F23K5/14
Filed: 1992-12-04
Abstract: A temperature compensated fuel control valve or regulator has a temperature sensor which senses the temperature of fuel entering the regulator. The temperature sensor controls the area of an orifice through which the fuel must pass in order to enter the burner. When the fuel is at low temperature, its viscosity will be higher and more of the orifice area will be exposed to the fuel. When the fuel is at high temperature, it will flow more easily and less of the orifice will be exposed to the fuel thereby allowing less fuel to pass to the burner.

Title: Apparatus for the cleaning of exhaust gases
Inventor: KURR KLAUS
IPC: B01D46/18
Filed: 1992-12-07
Abstract: Apparatus for cleaning exhaust gas from a combustion installation includes a soot filter which is positioned in the exhaust gas flow. The soot filter has a flexible filter band which in a first zone is subjected to a through flow of the exhaust gas and can be continuously or intermittently advanced and renewed from a storage roll by a drive.  The filter band is supported in the first zone on and movable by a flexible, gas permeable continuous transport band which provides the necessary longitudinal tension.  The filter band and the particles separated from the exhaust gas are burnt together in a second zone. Thus, both the filter band and the particles on it are disposed of in the apparatus itself thereby providing an economical filtering process.  The filter band need not be strong enough itself to withstand the exhaust gas pressures which are resisted by the transport band.
