Title: Improvements in and relating to the regulation of the fuel supply in combustion engines
IPC: F02D9/00
Filed: 1935-09-14
Abstract: 453,024. Fluid-pressure servomotorcontrol systems. ASKANIA-WERKE AKT.-GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU, 87, Kaiserallee, Friedenau, Berlin. Sept. 14, 1935, Nos. 25585 and 25586. Convention dates, Sept. 27, 1934 and July 29, 1935. [Class 135] In a fluid-pressure servomotor regulating the fuel supply to an internal-combustion engine such as an aircraft engine, and comprising a force-controller or relay responsive to changes in air density, the restoring impulse given to the restoring mechanism of the force controller by the servomotor varies in non-linear relation to the movement of the servomotor piston. In Fig. 1, an enclosed air chamber or bellows 2, located in or on the induction pipe changes its axial length according to the reciprocal value of the air density. This bellows, the stroke of which is reduced by the insertion of a fixed block 3, operates, through a bell-crank 6, on one end of a floating lever 8 pivoted intermediately to the control valve 14 and fulcrumed at its lower end G on a sliding cam 12 rigidly connected by rods 21, 22 to the servo-piston 17 controlling the fuel supply. The curve of the cam is of hyperbolic form, so that the movement of the piston 17 necessary to restore the control valve to the closed position shown is proportional to the reciprocal of the movement of the bellows 2. In cases where it is necessary to depart from exact proportionality in the fuel-air weight ratio, the cam 12 is constructed of laminµ 12', 12<11> &c., Fig. 5, adjustable at right angles to the rod 21 and clamped thereon. Thus the curve of the cam may be adjusted to suit the fuel consumption curve of any particular engine. In a modification, a pin on a rod similar to the rod 21 engages an inclined slot on one end of the floating lever. The servopiston is urged to its zero position, corresponding to the starting position for the engine by an adjustable spring.

Filed: 1972-06-03
Abstract: 1422952 Data processor fault diagnosis PLESSEY CO Ltd 23 May 1973 [3 June 1972] 26033/72 Heading G4A In a system comprising a plurality of processors each of which can address any location in any one of a number of storage modules, a processor in which a fault has been detected is connected to the address path from the other processors by a diagnostic interface unit which may be plugged in by an engineer or switched on to the path. The interface unit includes an address recognition and decoding unit AD for selecting monitor, control and data injection points within the processor for testing by a diagnostic program executed by another processor known to be functioning correctly. Decoded address signals AR enable blocks of gates GR1-GR8 for passing to the peripheral highway PDN the contents of an output register, the current instruction address register SCR, the data on highways H0, M0, M1, the current instruction, or blocks of micro command bits UPA, UPB. Similarly, if the control code accompanying the address supplied to unit AD indicates a write instead of a read operation, unit AD provides decoded address signals AW to enable blocks of gates GW1-GW6 to inject data on to highway H0 or into micro-bit registers UPA, UPB or to condition control registers M, REG1, REG2, SR. The MREG in conjunction with logic ML controls the system clock CLK to advance by a selected number of steps, e.g. one microinstruction step; one program instruction; to a particular program instruction (SCR compared with value in REG2); a selected number of microinstruction steps (value in SR); to a fault condition (UPA= 0); or to a particular microinstruction (UPA= SR). In addition logic ML can be arranged to supply the data set in REG 1 to highway H0, to inhibit microprogram decoding for the next microinstruction from the current address in UPA, and inhibit clocking of SCR to repeat the current instruction. The diagnostic program may be run as a low priority job on a good processor, and details of an exemplary diagnostic language are given in the Specification.

Abstract: 622,196. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 29, 1944, No. 26077. Convention date, Dec. 29, 1943. [Class 40 (vi)] [Also in Group XXXIX] A volume compressing circuit consists of an amplifier having a feedback path containing a bridge which is normally balanced so that no feedback occurs, means being provided for unbalancing the bridge in such a manner as to produce negative feedback if output exceeds a predetermined level. The Figure shows a balanced amplifier provided with a bridge having one diagonal connected between the anodes of the stage 12, and the other connected across the resistor 24 in the cathode circuit of stage 11. Two opposite arms of the bridge each comprise one half of the double triode, respectively in series with the resistors 45 and 46, resistors 47 and 48 forming the remaining arms. The bias applied to the grid of the triode is set by adjusting the potential divider 59 so that if there is no output from the diode the bridge is balanced. A portion of the output is taken from the secondary of the output transformer 14, amplified by valve 61, rectified by the diode, and the resultant D.C. voltage applied to vary the bias on the triodes and unbalance the bridge. A delay voltage is applied to the diode so that no feedback will occur until the output reaches a predetermined level.

[Also in Division H3] A switching system wherein current is supplied to a load in pulses from a direct current source comprises unidirectionally conductive switching devices, the triggering of which determines the mark space ratio of the pulses, a capacitor being provided to provide a reverse voltage to render one of the switching devices non-conductive. With a capacitor 1 initially charged so that its lower electrode is negative a load 9 will be supplied with current from a D.C. source A, B, when a triggering signal is applied to a controllable rectifier device 2. At the same time the capacitor 1 reverses its charge by virtue of a half-wave rectifier 4 in an oscillatory circuit 2, 5, 4. When a triggering signal is applied to a controllable rectifier device 3 it becomes conductive whereupon the charge on the capacitor 1 is applied to the rectifier device 2 as a reverse bias to render the device 2 non-conductive. The capacitor 1 discharges into an oscillatory circuit 3, 6, 7, 8 for one half-cycle when the current tends to reverse thus extinguishing the rectifier device 3. The capacitor 1 is left charged in its original polarity, the extent of the charge being dependent upon the load current. To limit the voltage to which the capacitor 1 is charged, a diode 11 connected as shown may be provided. The mark space ratio of the current pulses in the load 9 are thus determined by the triggering signals applied to the devices 2, 3. In other embodiments the rectifier 6 or the inductor 5 may be omitted or the rectifier 4 may be replaced by a controllable rectifier device which is triggered simultaneously with the rectifier device 2.

Abstract: 1,002,850. Magnetic tape recording and apparatus; associated working. E. K. COLE Ltd. June 30, 1964 [July 4, 1963], No. 26478/63. Heading G5R. [Also in Divisions B4 and G3] In a paper positioning control system for a guillotine a programme is recorded on a magnetic tape or wire 24 which is moved synchronously with the bed of the guillotine, by a sprocket 12, past a reading head 28. The head is displaced along a rod 30 by a linkage 32 actuated by solenoids 35, 36. Switches 37, 38 are actuated by an extension of the core of solenoid 35. When a signal is fed to a terminal C a bistable circuit 42 changes state so that an output pulse is derived from B to energize the solenoid 35 to move the head 28 from the right-hand toward the left-hand position thereby commencing a scan of a portion of the tape 24 and closing the switch 38. The output at B also switches on a transistor 48 to inhibit the input to a stop circuit 46 for a guillotine feed motor, not shown. When a pulse, due to a programmed position mark, is received by the head 28 while moving towards the left-hand position a signal is fed through an amplifier 44 to a slow-circuit 45 to cause the feed motor to slow-down. A pulse from the slow-circuit 45 changes the state of the bi-stable circuit 42 to provide an output at A so that the solenoid 36 is energized to return the head 28 to the right-hand position at a higher speed than the tape movement. During the return movement transistors 47, 51 are switched, switch 37 being closed, so that the repassing of the programme mask does not cause operationof circuits 45, 46. When the mask is again read by the head in the right-hand position, switch 38 being now closed, the stop circuit 46 is energized to stop the movement of the paper towards the guillotine and actuate a brake, not shown. Alternatively, if the head does not receive a pulse it is brought to rest at the lefthand position. The switch 37 is then closed by solenoid 35 to energize a fast start circuit for a fast forward speed motor, not shown. When the next mask is read the slow-speed circuit 45 is operated and the head returned to the righthand position by solenoid 36 to subsequently stop the paper feed through circuit 46.
