Title: Spark ignition systems
IPC: F02P3/05
Filed: 1972-07-01
Abstract: 1404064 Ignition systems E CHARLESWORTH 29 June 1973 [1 July 1972] 30900/72 Heading F1B In an ignition system comprising an ignition coil 3 in series with a contact breaker 1 and a power source, means are provided to maintain a large proportion of the current flow through the primary winding of the ignition coil at the instant when the contact breaker opens. When the contact breaker 1 opens a voltage starts to develop across the terminals of the device 5 with the polarity shown. A voltage consequently appears across the primary winding of the transformer 8 and this produces a voltage across the secondary winding of the transformer which causes current to flow through the resistor 10 to the base of the transistor 6. This causes the transistor 6 to turn on. The current which was previously flowing through the contact breaker now flows through the transistor 6. When the core of the transformer 8 saturates the transistor 6 switches off rapidly and current flow to the ignition coil, is interrupted. The diverting of current from the contact breaker at the instant of opening of the contacts reduces greatly the arcing across the contact faces. A modification comprising a thyristor associated with a transistor is described with reference to the drawings accompanying the Provisional Specification.

Title: Improvements in or relating to valve operating mechanism which is self adjusting to take up clearance in said mechanism
IPC: F01L1/22
Filed: 1933-11-09
Abstract: 424,362. Valve gear. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.- (Wilcox-Rich Corporation ; 9771, French Road, Detroit, Michigan, U.S.A.) Nov. 9, 1933, No. 31251. [Class 7 (vi)] A device for automatically taking up clearance in valve-operating mechanism of engines or machinery is provided with clutch means which locks the compensating means when the cam lifts the valve, but releases it when the valve closes. In the form shown in Fig. 5, a split nut 22 engages a screw-thread 30 on a tappet head 31 contacting with the valve stem, and has a conical surface 25 bearing on a similar surface at the top of the tappet member 20, which slides in a fixed guide 14, a spring 34 being arranged so as to tend to screw the head 31 towards the valve stem. The guide 14 is adjusted by means of shims 18 so that its upper edge lightly contacts with a flange 24 on the nut 22, when the valve is closed. During the operation of the valve, the conical surface 25 acts to clutch the split nut 22 on to the screw 30 and prevent relative rotation, but when this pressure is released as the valve closes, any clearance that has formed is automatically taken up by relative movement between the screw and nut. This release of the clutching action may be further ensured by reducing the heel portion 12 of the cam. A construction of cam is described for this purpose having an eccentric reduced heel portion joined by concentric curves to the sides of the cam lift. In a modification, the screwthread is formed on the valve stem, which then engages the split nut directly. Fig. 18 shows another form, in which the tappet head 98 carries pins 100 resting on inclined planes 91 formed on a member 88, which has a coned engagement at 89 with the tappet 82. This tappet carries a roller 79 which engages a reduced heel 78 on the cam. This reduced heel is only formed at the centre of the cam, the sides 77 of the heel being made concentric with the cam shaft and engaging a sleeve 76 sliding between the tappet 82 and the guide 16, the upper end of the sleeve 76 engaging the head 90 of the member 88. In another form, the tappet head has an inclined lower surface which engages a wedge pressed radially by a spring across the sleeve, the cam-engaging tappet having a V-shaped clutch engagement at its upper end with the wedge.

Abstract: 780,170. Pulse discriminating circuits. KOLSTER-BRANDES, Ltd. Nov. 3, 1954, No. 31765/54. Class 40 (6). In a television circuit for separating frames synchronizing pulses from line pulses the mixed pulses are applied to a valve 1 having in its anode circuit an inductor 4 having a time constant at least as long as the frame pulses and connected in parallel with a rectifier 6 poled so as to carry part of the anode current of the valve, the voltage across the inductor being applied to a voltage clipper to obtain pulses coincident with the end of each frame pulse. The synchronizing pulses render the valve conducting and a current builds up in the inductor 4. At the end of the pulse the voltage at the anode of the valve swings positively to a value which is larger after a frame pulse than after the line pulse. Accordingly the frame pulses may be separated by the clipper. A second inductor 5 having a short time constant and in parallel with a reversely connected diode 7 produces a pulse at the point 10 when the line synchronizing pulses cause the valve to become conductive, accordingly line synchronizing pulses may be obtained from point 10. The diode 7 prevents a pulse of opposite polarity being produced at the end of the line pulses.
