Title: Overvoltage Protection Circuits
IPC: H02H3/20
Filed: 1967-07-12
Abstract: 1,157,733. Protective arrangements. WESTINGHOUSE ELECTRIC CORP. 12 July, 1967 [19 Sept., 1966], No. 31993/67. Heading H2K. [Also in Division H3] An overvoltage protective arrangement comprises a time delay circuit including a capacitor 37 and a voltage " sensing " circuit 16 including means for preventing the charging of the capacitor 37 until the voltage reaches a predetermined value, the voltage being separately applied to the two circuits 14, 16 to enable independent adjustment of the pick-up voltage level and the time delay. The capacitor 37 is normally short-circuited by a transistor 35, but charges through a Zener diode 27 and variable resistor 28 when the transistor 35 is rendered non-conductive by a transistor 33 which conducts when the voltage is sufficient to cause a Zener diode 29 to break down. The time delay circuit may have a simple transistor amplifier, but the arrangement shown has a differential amplifier in which the voltage V 2  across the capacitor 37 is applied to a normally non- conducting transistor 44 for comparison with a fixed reference voltage V 3  applied to a normally conducting transistor 42. When the voltage V 2  is sufficient to overcome the reverse bias across the common emitter resistor 46, the transistor 44 conducts and causes a transistor 48 to provide an output, e.g. to effect the protection of a. generator.

Title: Improvements in arrangements for operating electric discharge lamps to produce intense flashes of light
IPC: H05B41/32
Filed: 1948-12-15
Abstract: 656,767. Supply systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd., and BOWTELL, J. N. Dec. 15, 1948, No. 32514. [Class 38 (iv)] To produce short, intense flashes in a discharge lamp 15, a large condenser 7, charged from a source 1, 2, is discharged through the lamp, initiation of the discharge being effected by including in the discharge circuit a small inductance 9 and shunting across the leads to the lamp a small condenser 10 in series with means such as a spark-gap 11 for shockexciting the oscillatory circuit, constituted by the inductance and two condensers, to produce a train of high-frequency voltage waves to initiate the lamp discharge. The spark-gap may be triggered by shunting the secondary 12 of an induction coil 13 across the spark-gap and controlling the current in the primary 14 by a gas-filled valve (not shown). The time constant of the charging circuit of condenser 7, comprising resistance 8, is made sufficiently high to prevent continuous operation of the lamp after flashing. To ensure simultaneous flashing of a pair of lamps, the lamps are connected in series and a resistance is shunted across each, of the same value, to ensure equal division of the initiating high-frequency voltage waves across the lamps.
