Title: Control of x-ray tube and like circuits

IPC: H05G1/56
Filed: 1960-07-14
Abstract: 978,152. Supply systems for X-ray tubes. GENERAL RADIOLOGICAL Ltd. April 4, 1961 [July 14, 1960], No. 24603/60. Heading H2H.  D.C. excitation is applied to the core of a transformer supplying an X-ray tube prior to its connection to an A.C. mains supply being effected at or near an instant of zero voltage where the rate of change of voltage is such that the first half wave of the supply polarizes the said core oppositely to the magnetic field produced by the D.C. excitation. Energizing a relay coil RLA (not shown) closes contacts A1, A2, thus heating the cathode of an X-ray tube 1 through a transformer 3, and contact A4 which completes a D.C. energizing circuit through normally closed relay contact E1, for polarizing the core of an H.T. transformer T2 from a D.C. supply (also not shown). After a delay, a relay energizing coil RLE (not shown) is able to close contacts E2, E3 supplying H.T. to a pair of thyratrons or similar valve or semiconductor devices V2, V3, whilst a normally closed negative bias connecting contact E4 is opened. Together with contact E1 the control grid of V2 is supplied with negative full wave rectified A.C. through rectifier 5 and its screen grid with a low mains derived A.C. voltage phase shifted through 90 degrees. Thus, V2 is cut off during alternate half cycles of the supply, thereby preventing it from conducting every time the grid control grid rises to zero volts and ensuring that its ignition will only occur when the mains voltage is passing through zero with a rate of change of such a sign, as to cause the magnetism produced by the first half wave in the core to oppose that of the D.C. supply. Ignition of V2 causes a contactor operating coil RLF to be energized, thus successively closing contacts F1, F2, F3 supplying mains to the transformer T2 through normally closed contact G1 and voltage selecting transformer T1, and thus commence an X-ray exposure. Opening contact E4 causes positive bias to V3 to rise at a rate determined by R7 and the capacitor selected by switch 6, firstly causing V3 to conduct and energize contactor operating coil RLG which opens contact G1 thus terminating the exposure. The operating time of contactor RLG is made an integral number of half cycles, so that the circuit is broken at or near zero voltage. If several rapid exposures are made without interruption of the heater supply, the tube circuit termination may be arranged to momentarily excite a " slow release " relay by which the D.C. circuit may be closed.
