Title: Discharge lamp start and supply circuit
Inventor: CHAPMAN DONALD FREDERICK
IPC: H05B41/04
Filed: 1983-05-17
Abstract: Discharge lamps and in particular low pressure sodium (SOX) lamps have been started by circuits having a two terminal electronic starter and a series connected choke for ballast stabilisation. Particularly with higher power lamps and if supply voltage drops the available voltage may be insufficient to ensure lamp reignition throughout the run-up period. It is also possible for the lamp to settle in a low power high voltage state, never attaining full operating power. To correct this state in a circuit in which the lamp 1 in parallel with the ignitor 2 is connected in series with a ballast 3a, 3b across the mains supply with a power factor correction capacitor 6 the circuit is adapted to increase the lamp voltage at which peak power is obtained. To that end a tapping 7 is provided on the choke and the power factor connection capacitor 6 is connected between the tapping and the opposing lamp terminal. A high frequency blocking choke 8, or a tuned filter network, may be provided to prevent ignition pulses being fed into the mains supply. <IMAGE>

Title: Shutter diaphragm
Inventor: KOCHAN ROLF
IPC: G03B9/24
Filed: 1984-10-11
Abstract: In a control device for a shutter diaphragm, the shutter-opening action of a shutter-operating member 11 is under the action of a spring 17 connected to a closure member 18 and is terminated abruptly by the locking of a detent 27 connected to member 11 with teeth 36 on member 18 and simultaneous release of member 18 to return member 11 to its original position under the action of a spring 2. On shutter release, catch 29 pivots clockwise to release tensioning member 40/42 which moves upwards (to position shown) under action of spring 38 to start the shutter-timing process by opening switch 47 and the exposure process by releasing member 11 from detent 22. Member 11 moves downwards (to position shown) to operate shutter- opening segment lever 8. On completion of the shutter-timing process, electromagnet 45 is released and signal lever 24 is pivoted clockwise, allowing detent 27 to engage teeth 36 under action of spring 28, preventing further opening movement of member 11, and releasing member 18, which moves upwards (from position shown) together with member 11, to effect shutter closing. Recocking is effected by pushing member 37 downwards, member 18 thereby being also moved downwards and springs 17, 21 and 38 tensioned. <IMAGE>

Title: Data processing system with pluggable option cards
Inventor: HEATH CHESTER ASBURY
IPC: G06F12/06
Filed: 1988-03-07
Abstract: A data processing system includes a central processing unit (CPU), a main memory unit, and input/output (I/O) sockets, each adapted to receive a selected one of a plurality of different and/or similar option cards. Each card contains (or is connected to) and controls a respective peripheral device, and each card is pre-wired with an ID value corresponding to its card type. Programmable option registers on each card store parameters such as address information, priority levels, and other system resource parameters. A setup routine, during initial power-on, retrieves and stores the appropriate parameters in the I/O cards and also in socket locations in main memory, one location being assigned to each input/output socket. Each socket location is adapted to hold the parameters associated with the card inserted in its respective socket and the card ID value. That portion of main memory containing the socket locations is adapted to maintain the parameter and ID information by means of battery power when system power fails or is disconnected, i.e., a non-volatile memory portion. Subsequent power-on routines are simplified by merely transferring parameters from the memory to the card registers if the status of all the sockets has not changed since the last power-down.
