Title: Start, hot restart and operating circuit for an HIO lamp
Inventor: NUCKOLLS JOE ALLEN
IPC: H05B41/38
Filed: 1987-06-24
Abstract: A circuit 16, (76), (119), (Figs. 3 to 9), responsive to the voltage across a ballast reactor 14, or to current through the lamp 10, causes a fist switch 18 to open to deactivate a pulse generator 12 in response to starting of lamp 10. Generator 12 produces high voltage pulses suitable for starting and hot restarting of the lamp. If the lamp does not start within a predetermined interval, a second switch 20, (115), (Figs. 6, 7), is latched open to inhibit pulse generator 12. The second switch may be opened in response to closure of a thermally operated switch (135), (Figs. 6, 7), heated by a resistor (140) associated with the starting pulse generator. Alternatively, Fig. 1, (and Figs. 2 to 5, 8, 9), timing circuits 22, 28 cause the second switch 20 to be repeatedly opened and closed to establish alternating active and inactive periods for generator 12, until time 28 causes switch 20 to he latched open in response to heating of an NTC resistor 26, or a switch, by a resistor 25. The pulse generator 12 may include a capacitor (42) periodically discharged through the primary winding of a step-up transformer. These pulses may establish a streamer arc in the lamp, whereafter a capacitor (80a) connected to a tap on a ballast reactor (72a), Fig 8, 14a, (Fig 9), may discharge to apply an intermediate level current pulse, having a current magnitude greater than normal lamp operating current and a voltage of the order of normal lamp operating voltage, to push the lamp into full ionization. <IMAGE>

Title: Vehicle anti-lock braking
Inventor: ANTROBUS PHILIP MICHAEL
IPC: B60T8/42
Filed: 1987-07-14
Abstract: The invention provides a control system for an antilock braking system including a servo brake pressure modulating mechanism (50:50') which may be controlled by two solenoid valves (70 and 78). Solenoid valve (70) when energised causes reduction in the braking effort and when de-energised causes reapplication of the braking effort and solenoid valve (78) permits reduction or reapplication of the braking effort at a slow rate when de-energised and at a fast rate when energised. The control means includes sensing means (11;11') associated with a wheel for producing a signal corresponding to the speed of the wheel; means (103) for deriving there from a signal corresponding to wheel acceleration or deceleration; means (107,114,72) for energising the solenoid valve (70) when the wheel deceleration reaches a first predetermined magnitude; means (108,115,114,72) for de- energising the solenoid valve (70) when wheel deceleration falls to a second predetermined magnitude; means (109,116,117,80) for energising solenoid valve (78) when wheel acceleration reaches a first predetermined magnitude; and means (116,117,80) for de-energising the second solenoid valve (78) after a predetermined time period has elapsed from when the wheel acceleration reached said first predetermined magnitude. The first predetermined magnitude may be increased and permitted to decay to its original valve when the first valve is switched to its reapply mode and the second valve may be switched to its fast mode when wheel deceleration reaches a third deceleration magnitude greater than the first, which third magnitude may also be increased and permitted to decay to its signal value.
