Title: Spark ignition systems
Inventor: PHILLIPS BRIAN LESLIE
IPC: F02P3/08
Filed: 1965-03-10
Abstract: 1,106,923. Ignition systems. JOSEPH LUCAS (INDUSTRIES) Ltd. March 3, 1966 [March 10, 1965], No. 10110/65. Heading F1B. A spark ignition system includes a semiconductor switch controlling the production of the required sparks and a pair of transformers providing signals to the control terminal of the switch for turning the switch on and off respectively. At the instant when a spark is required any convenient known means operated by the engine causes a negative signal to appear at the terminal 26. This signal turns the transistor 24 off and so the transistor 23 is turned on and current builds up in the winding 22. The e.m.f. in the winding 19 is blocked by the diode 17. When the transistor 23 is switched on the transistor 36 tends to switch off and the transistor 34 tends to switch on. The transistors 34, 36 act in conjunction with their associated components to cause a pulse to be applied to the winding 33 until the transistor 23 is turned off. Current is fed by the winding 31 to the switch 15 to turn it on. When the switch 15 is turned on the capacitor 42 discharges through the winding 43 to produce the required spark. While the switch 15 is on current builds up in the series circuit 13, 14, 15, 16 until when a predetermined current is reached the voltage across the resistor 16 turns the transistor 24 on. The transistors 34, 36 now revert to their original state so removing the forward drive to the switch 15 and the transistor 23 is turned off. The e.m.f. in the winding 19 provides a negative gate-cathode current to turn the switch off. The energy stored in the inductor 13 is now transferred to the capacitor 42 by way of the diode 48. The switch 15 may be a gate controlled switch or a transistor. In a modification the resistors 25, 27 are connected to the line 11 through an additional resistor and a Zener diode is added. The system may include resistors which render the operation of the system substantially independent of temperature variations.

Abstract: 358,064. Valve circuits. GERHARD, E., 1, Zõhstrasse, Fiirth, Bavaria, Germany. March 31, 1930, No. 10237. Convention date, April 2, 1929. [Class 40 (v).] In a valve arranged to generate ultra shortwave oscillations by virtue of a highly positively charged grid and a plate nearly at zero potential, an oscillatory circuit of a different natural frequency from the primary oscillations is connected in the plate or grid circuit, the voltages on the electrodes being so chosen that the valve is operating on the drooping part of the dynamic characteristic. This results in modulation of the ultra high-frequency primary oscillations by secondary oscillations of a lower radio frequency. As a transmitter, the valve 2, Fig. 2, is coupled to a dipole aerial 1 and the secondary oscillatory circuit 10, 11 is coupled to a low-frequency winding 22, through an iron core 21, this winding being supplied with low-frequency modulating currents. As a receiver the oscillatory circuit 10, 11, Fig. 1, is coupled to a coil 12 connected to an ordinary high-frequency amplifier 13, detector 14 and low-frequency amplifier 8. If the received wave is not modulated by an audiofrequency, the circuit 10, 11 may produce oscillations which will heterodyne the high-frequency modulation of the incoming signals. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a transmitting modulating system in which the high-frequency oscillations of the circuit 10, 11, Fig. 3 (Cancelled) are amplified by the valve 17 and fed back into the circuit 10, 11 the low-frequency modulating potentials being applied between the grid and cathode of the valve 17. This subject-matter does not appear in the Specification as accepted.
