[Class 38 (iv)] A supply system for an X-ray tube 5 having cathodes 7, 8 giving, respectively, small and large focal spots, has means whereby the normal heating circuit of cathode 7 may be interrupted and cathode 8 heated substantially instantaneously to emitting temperature. As shown in Fig. 1, cathode 7 is supplied through a transformer 16 from lines L1, L2 over normally closed contacts 25 of a relay 36. Cathode 8 is permanently energized, but below emission temperature, through transformer 18 in series with a resistor 29. When it is desired to change from a small to large focal spot, button 32. is closed, thereby energizing the relay which picks up, locks in over contacts 37, opens the primary circuit of transformer 16 at contacts 25, short-circuits resistor 29 at contacts 37 to apply full heater voltage to cathode 8, and by closure of contacts 56 triggers a tube 42 which discharges a condenser 40 into cathode 8 to cause its instantaneous heating. Tube 42 is normally held off by a bias voltage 43 and is triggered by the discharge of a condenser 49 through a transformer 46 which occurs when a hold-off bias on a tube 50 is reduced by closure of relay contacts 56. Opening of button 34 restores normal working conditions. Buttons 32, 34 may be replaced by switches actuated by the insertion and withdrawal of the cassette. In the modified arrangement of Fig. 2, tube 42 is triggered to discharge condenser 40, the primary winding of transformer 18 is energized and the supply to transformer 16 is interrupted by a single pole change-over switch 60.

Abstract: 460,436. Control of D.C. motors. ATLANTIC REFINING CO. May 24, 1935, No. 15229. Convention date, May 31, 1934. [Class 38 (iii)] [Also in Group XXXV] Varying E.M.F.-An electric transmission system in which a reversible motor is supplied with power from a generator is provided with means for controlling the rate at which power is increased during the accelerating period, the field strength of the generator or.motor being then controlled by varying resistance in the field by an auxiliary motor which moves at a decreasing speed to increase the power developed in proportion to the cube of the elapsed time from starting. In the arrangement shown, the field strength of the generator 53 is regulated, the motor 48 being reversed by switch 42. The armatures of the generator and motor are connected directly by leads 49, 50 and their fields 47, 51 are supplied from mains 11, 12. The controller handle 8 when set to give any speed ahead or astern, for example, the position 8<1> for full speed ahead. supplies current to the bar 7, sliding contact 13, bar h and winding 23 operating relay 21 which closes a circuit through forward field winding 20 of reversible series motor 17. The motor 17, through bevel gearing, adjusts screws 15, 15<1>, by which bars 14 and 28 are moved upwardly until bar contact 13 on bar 14 reaches the gap in bar h, when relay 21 opens. Should relay 21 fail to open, a contact breaker 32<1>, carried by the bar 28, opens limit switch 31<1> in the circuit of motor 17. The first movement from neutral if the bar 28 operates reverse switch 42 for the motor field 47. The motor 17 rotates during this period at a decreasing speed due to the gradual introduction of resistances 30<1> as the contact 29<1> carried by the bar 28 moves upwards. At the same time resistance 35<1> is cut out of the generator field 51 at a decreasing rate by contact 34<1> on bar 28, until the motor 48 reaches the predetermined speed depending upon the setting of the controller 8. Similar resistances 30, 35 are rendered effective when going astern. When reducing forward speed or stopping, the motor 17 is reversed and returns bars 14, 28 to or towards their neutral position corresponding to the gap in bar a. The motor 17 then operates the whole time at full speed since its circuit is completed through contact 29 and bar 26<1> independently of resistance 30<1>.
