Patent CA-1151397-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE    A highly effective and energy efficient new method for processing various organic materials into more useful states include enclosing a material in the form of aggregate pieces within a chamber having a vertical extent, at least partly closing the chamber to air to control the amount of oxygen contained therein, conveying the aggregate pieces through the vertical extent within a predetermined time by vibratory action, heating the chamber to a preselected temperature sufficient for converting volatile hydrocarbon constituents of the material to a gaseous state, and removing off-gases from the chamber for further use.  Apparatus used in carrying out the method includes preferably first and second chambers, each chamber having a continuous length tray spiraling along a vertical extent of the chamber and with the tray surrounding a vertical support.  Vibration generators secured to the support impart vibratory forces to the tray to cause pieces of material to be conveyed from one end of the tray to the other, e.g., from the bottom to top, by vibratory action.  Heating of the material is carried out in one such chamber and with resultant off-gases supporting combustion for such heating.  After heating, material is transferred from the first chamber to a second chamber, also closed to air, for cooling as pieces similarly traverse the vertical extent of a similar vibration-driven spiral conveyor in the second chamber.  If drying of material is desired to reduce moisture content prior to carbonization, this can be accomplished in a third chamber heated with combustion gases from heating of the first chamber.  This third chamber can also be used simply as a dryer for material that is not to be further processed for carbonization, with material traversing the vertical extent of a similar vibration-driven spiral conveyor as with the first and second chambers.  The processing may involve converting wood chips or other lignocellulosic or biomass materials into charcoal or carbon, carbonization or pyrolysis or reduction of moisture content of such materials, converting tire waste into carbon black, extraction of keragen or bitumen from oil, shales or sands, etc., converting coal into coke, as well as gasification of coal, as well as blending material of the same or different components that require mixing under higher than atmospheric temperatures.

Abstract: RCA 74, 055 ABSTRACT OF THE DISCLOSURE           A preamplifier is provided which couples a television tuner to a surface acoustic wave (SAW) filter and amplifies the I.F. signals supplied by the tuner so as to overcome the signal losses of the SAW filter.  The preamplifier comprises a single transistor, the gain of which may be varied to provide desired gain and noise performance for the entire tuner-SAW filter-I.F. system. The preamplifier may also include a tuned circuit which preshapes the I.F. signal response characteristic.  The tuned circuit provides the preshaping by exhibiting an additional pole in the vicinity of the vestigial slope portion of the I.F. signal response characteristic.

Abstract: PHD. 79-154                     10 ABSTRACT:       A variable-gain differential amplifier comprises a first long-tailed transistor pair between the bases of which the input signal is applied.  The emitter-collector paths of the transistors of the first pair are included in the tails of second and third long-tailed transistor pairs respectively and load resistors between the lower termi-nals of which the output signal appears are included in the respective collector circuits of one transistor of each of the second and third pairs, and hence in the collector cir-cuits of the respective transistors of the first pair.  The second and third pairs are controlled by a gain control sig-nal thereby diverting a variable proportion of the collector signal currents of the transistors of the first pair away from the load resistors and hence varying the gain of the circuit.  In order that variations in the gain control sig-nal should not affect the d.c. level at the amplifier out-put the collectors of the other transistors of the second and third pairs are commoned and connected to the input of a current splitter the two output currents of which are fed to the respective load resistors, whereby compensating for any changes in the standing currents through the load resistors which would otherwise be produced by changes in the gain control voltage.

Abstract: ABSTRACT OF THE DISCLOSURE     A mobile radio telephone system is described.  Mobile stations are free to travel to different zones covered by respective base stations.  Speech channel transmitter/receivers are used to transmit and receive speech and access channel transmitter/receivers are used to control calls for the mobile stations.  The system has a detection circuit which detects from the output of the access channel receiver of a mobile station a calling signal and a test calling signal.  A controller connected to the output of the detection circuit transmits the test calling signal to the access channel receiver if the detection output of the detection circuit is not received within a first predetermined time interval.  The control generates a trouble signal if the detection output is not received within a second predetermined interval after the transmission of the test calling signal.     The second interval is shorter than the first.  The invention automatically detects trouble on an access channel without hindering communication by other mobile stations sending out ordinary call signals.

Abstract: Abstract of the Disclosure A fuel control system for a spark ignition internal combustion engine of the type having a source of fuel and a pump for supplying the fuel from the fuel source and to the engine at variable flow rates.  The fuel control system of the present invention is particularly suited for a reciprocating piston aircraft engine and is designed to minimize brake specific fuel consumption of the engine during steady state engine operation.  The fuel control system utilizes a micro-processor to determine the peak value of the exhaust gas temperature and, once the peak has been found, repeatedly decreases the fuel flow rate to the engine in predetermined increments until the exhaust gas temperature is less than its peak value by a predetermined amount.  At this time, the fuel control system maintains a constant fuel flow rate to the engine.
