Title: Means for the progressive lighting of electrical discharge tubes
IPC: H05B41/24
Filed: 1957-03-04
Abstract: 814,916. Supply systems for space discharge apparatus. TRIFLUX SOC. March 4, 1957 [March 16, 1956], No. 7070/57. Class 38 (4). The voltage applied to a discharge lamp is gradually increased from zero to a maximum whereby the lamp is progressively illuminated along its length, the supply to the lamp being changed-when it is fully energized-from the variable voltage supply to a fixed voltage supply. Voltage at a fixed high frequency of between 20 and 100 kilocycles per second is generated by an oscillator 1 of any suitable known kind, there being two coupling windings 4, 5 associated with the output winding 3 of the oscillator, this latter winding being in a circuit which is tuned to the frequency generated by the oscillator 1. The voltage applied to a discharge lamp 6 over relay contact 12 is progressively increased from zero by varying the coupling of the winding 4 with the winding 3 whereby the lamp 6 is progressively illuminated along its length. When the lamp 6 is fully illuminated the current passing through a relay operating coil 9, which is connected in parallel with a half-wave rectifier 14 and a condenser 15, is sufficient to cause the relay to change over from contact 12 to contact 13 whereby the lamp is now supplied from the winding 5 fixedly coupled with the winding 3. The lamp is thus maintained fully illuminated. In another embodiment a plurality of lamps are successively lit the relay operating to connect the succeeding lamp in a series to the winding 4 as well as changing the supply to the preceding lamp from the variable to the fixed voltage winding. In yet other embodiments the relay may be connected in the supply lines instead of being associated with the lamp current. Arrangements are also described whereby the alternate lamps in a series may be energized or whereby lamps may be cyclically operated. Specification 768,535 is referred to.

IPC: F15B13/04
Filed: 1973-02-15
Abstract: 1412485 Valves R BERINGER K STERL K GOGOL F LEUTENEGGER and W OLDANI [trading as BERINGER HYDRAULIK R BERINGER & CO] 15 Feb 1973 [18 Feb 1972] 7402/73 Heading F2V [Also in Division F1] A load independent control apparatus comprises a pair of slide control valves 2, a valve 3 which maintains a constant yet adjustable pressure difference between a pump (connected to conduit 51) and consumer units (connected across ports 8 and 9 of the slide control valves 2),  a pair of return conduits 6 interconnected by bore 62, the lower conduit 6 being connected to a tank by a bore 61, and a pair of sensing conduits 7 interconnected by a bore 71 which communicates the pressures prevailing in the consumer units to the valve 3 before any of the units are connected to the pump. The conduits and bores are all bored on a boring machine and closed where shown by plugs 70. Each slide valve bore 4 has a widened end 41 so that a bore 73 may be drilled connecting a sensing conduit 7 with a channel 42 in the bores. The valve 3 (Fig. 5) comprises a piston 31 having a series of passages so that pressure in conduit 51 may be directed to the underside of the piston against an adjustable spring 35. The spring chamber is connected to the bore 71 by bore 110 and channel 74. A second piston 111 slides in the bore 110 and has its upper side open to pressure in the spring chamber. The piston 111 carries a pair of flanges 112, 113 which control fluid from and to the spring chamber 36 respectively. The channel 74 extends to a bore 120 in which an excess pressure valve is located. The common return conduit 62 is connected via channel 76, 75 to the bore 110. Operation.-When one of the slide control valves is moved out of the neutral position, the bore 29 connects with channel 42 so that pressure in conduit 8 is communicated to the spring chamber 36 before the consumer unit is connected to the pump channel 5. Therefore the valve 3 throttles fluid from the bore 51 to bore 61 so that the pressure of the pump adjusts to the pressure of the consumer unit. Thereafter the conduit 8 is connected to the conduit 5. On return of the slide valve to the neutral position, the spring chamber 36 is exhausted via channels 74, 75. In Figs. 7 and 8 (not shown) the pump conduit (5) is connected to the slide valve bores (4) by passages (52) which house non-return valves (130) set to give a predetermined pressure drop.

Filed: 1974-02-20
Abstract: 1430925 Travelling-wave tubes VARIAN ASSOCIATES 20 Feb 1974 [20 Feb 1973] 7757/74 Heading H1D A dual-mode travelling-wave tube capable of continuous wave or pulsed operation, at respective power levels differing by as much as 10 db., includes means providing a switching signal which charges the beam current from a first value to a second value at least several times as great, and means coupled to an output section of the slow-wave structure and responsive to the switching signal for changing both the phase velocity of microwave power flow along the section, and the effective length of the section which interacts with the electron beam. In the embodiment of Fig. 2, the output section 19 of the severed slow-wave helix is coupled to the metal envelope of the tube by a plurality of varactor diodes 38 and 381, the voltage divider 49 ensuring that the switching signal, which alters the beam current by application to a high mÁ control grid (32, Fig. 1, not shown) biases the two sets of diodes by different amounts and hence produces different loading by them of the associated portions of the slowwave structure, such that the phase velocity of one portion is charged to maintain synchronism with the charged velocity of the beam, while the other portion is removed from synchronism with the beam, thereby shortening the length of the structure interacting with the beam. In other embodiments, varactor diodes 381 are replaced by PIN diodes, which may have series attenuators (42, Fig. 1, not shown), and both diodes and attenuators may alternatively be located outside the envelope (Fig. 5, not shown); or a metallic shell (39<SP>1</SP>, Fig. 6, not shown) may be disposed between the helix and the tube envelope, and coupled to the latter by PIN diodes (56), the bias on which thereby controls the capacitive loading of the helix, the shell exhibiting different dimensions over two different sections; or diode/capacitor/ attenuator and diode/capacitor combinations may be connected between adjacent turns of the helix. The various circuit components may be formed by printed and integrated circuit techniques on one of the ceramic support rods for the helix (Fig. 3, not shown). The slow-wave structure may alternatively be of ring-bar or vane-loaded double meander form, and the beam may be focused by a solenoid or a periodic permanent magnet system constituting the tube envelope.
