Title: System for the transmission of binary coded messages
IPC: H04B7/212
Filed: 1969-10-24
Abstract: 1,274,537. Multiplex pulse code signalling. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 24 Oct., 1969 [24 Oct., 1968], No. 52356/69. Heading H4L. In a P.C.M. system for communication between earth stations via a satellite repeater station, of the type in which the earth stations simultaneously transmit data in time sequence which is modulated by a binary coded address signal, transmission channels normally allotted to one station but not used are arranged to be used by another station the data signal from which is modulated by an address signal different from its normal address signal and that of the station normally allocated the channels. Fig. 1 shows the channel utilization of earth stations A, B, C. Synchronization signals S are followed by control signals V in turn followed by the data channels in time division multiplex. All the channels of station A are in use and it seeks for vacant channels such as are shown for stations B and C, preferably via a master station acting as an exchange, a special address signal being used to identify the additional channels utilized by station A. It is suggested that this may take the form of a quadrature phase shift of the carrier wave. The bit frequency of a station with unused channels is reduced so that the transmission takes up the complete frame period and leaves gaps between pulses for use by other stations.

Abstract: 1,146,815. Controlling burners. NORTH WESTERN GAS BOARD. 1 March, 1968 [2 Dec., 1966], No. 54095/66. Heading F4T. In a control system for a fuel burner array including primary burners and secondary burners ignited therefrom the control to the secondary burners is unlocked when fuel is supplied to a predetermined number of primary burners. Fuel is supplied to the primary burners via electrically operated valves 1 and closing of the energizing switch 3 causes a D.C. voltage to be applied to a potential divider comprising a relatively large resistor 5, a unidirectional device 4 and a relatively small resistor 6 common to all the divider circuits so that the total voltage across the resistor 6 provides a count of the number of primary burners operating, this voltage being compared with a reference voltage, derived from a potentiometer 8, by means of a transistor 7 which conducts at the predetermined voltage to operate relay W/1 and close   switch W1 and thus close switches L1, L2 via relay L/2 and unlock the control to the secondary burners. Closing of a switch 11 then causes fuel valves 13, of the secondary burners, to open. A Zener diode 15 prevents overloading of the transistor 7.

Metal oxide semi-conductor field effect transistors are used as cross-points in a telecommunications switch. As shown in Fig. 4 an MOS cross-point, such as T11, between horizontals H and verticals V of a a matrix, is switched by an associated bi-stable All in response to a vertical select signal C and a horizontal select signal S applied to a gate P11 which also requires a signal El indicating that all crosspoints of the row are free. The signals such as E1 are derived from the set outputs of the bistables A1 to Am of the row applied to a NOR gate G. The vertical select signals C are applied to reset all vertical column bi-stables (released connections being left uncleared) before being applied as inputs to gates P over delay circuits L. The gates P, the bi-stables A and the delay circuits L, including the necessary resistive components, are constituted by MOS transistors, Fig. 5, not shown, so that each cross-point and associated circuitry can be constructed in the form of an integrated circuit. Fig. 2 shows how MOS transistors Ta, Tb, Tc switched in cascade connect stations D1, D2, with a one-wire oneway circuit including transistors T1, T2, the low impedance input and high impedance output of which make the transmission of A.C. independent of the saturation resistance of the MOS transistors.

Title: Fuel injection control systems
IPC: F02M51/02
Filed: 1978-12-20
Abstract: A fuel injection control system for an internal combustion engine utilizes a metering unit to continually monitor air flow-rate to the engine and provide a pulse width modulated (PWM) digital signal which has a duty ratio representative of the air flow-rate. The duty ratio is the "on" period of the PWM signal divided by the total cycle period, which period is not related to engine speed. A further electrical signal indicative of engine speed is derived from the vehicle ignition system and the two signals are processed with the aid of a digital processor to provide an injector operating pulse. The system thus avoids use of A/D convertors normally associated with digital processors in this field and has a fast response time at all engine speeds. A means of fuel enrichment for times of rapid throttle opening is also disclosed as well as means for disabling the fuel supply on over-run. The air flow meter comprises a continuously rotating drum (21) having a cut out which passes between a light source and photodetector which is axially displaced against spring 3 by the air flow. Magnetic Hall effect or varie- switched oscillators may be used. <IMAGE>
