Title: Manufacturing electric devices having sealed envelopes
IPC: H01K3/00
Filed: 1972-08-11
Abstract: 1419099 Discharge tubes; electric incandescent lamps THORN ELECTRICAL INDUSTRIES Ltd 10 Aug 1973 [11 Aug 1972] 37648/72 Headings H1D and H1F A method of manufacturing electric devices having envelopes which contain dosings of at least one volatile and/or gaseous constitutent includes the steps of placing a sealed capsule 20 containing a dosing substance inside an envelope 11, sealing the envelope and, after sealing, perforating the capsule by directing a beam 25 of radiation from a laser through the envelope and focusing the beam on to the surface of the capsule 20 thereby enabling the dosing substance to be released into the interior of the envelope 11. The capsule 20 may be made of iron or steel but is preferably made of aluminium which acts as a getter, particularly when the dosing substance is mercury 21 which forms an efficient gettering amalgam with aluminium vapourized from the capsule material. The method may be applied to thermionic valves, discharge lamps or to tungsten-halogen filament lamps in which case the dosing substance is a volatile halide or halogen. As shown the capsule 20 is connected by a spur wire 22 to a lead wire 16 of a discharge lamp having a fluorescent coating 12 which is omitted from the end of the envelope 11 to leave a clear area 13 through which the laser beam 25 is directed. The capsule 20 may alternatively be located within a sealed tubulation attached to the envelope and opening to the interior thereof, the capsule being perforated to release the dosing substance and the tubulation then being tipped off and thereby detached from the envelope complete with the emptied capsule. The envelope 11 may contain argon or other starting gas in addition to a dosing substance of mercury or sodium. Specification 1,419,098 is referred to.

Abstract: 934,364. Axial-flow and helico-centrifugal pumps and compressors; turbines. SULZER FRERES S.A. Nov. 2, 1960 [Nov. 3, 1959], No. 37718/60. Classes 110 (1) and 110 (3). In a multi-stage machine operable in a hydro-electric power station as a pump to deliver water to a high-level reservoir when surplus energy is being generated by an associated power plant and, during periods of heavy demand, operable as a turbine driven by water taken from the reservoir to drive an electric generator, at least the last stage of the machine (when considered as a pump) is provided with adjustable rotor blades 5. This permits the blades 5 to be adjusted for the most efficient operation of the machine as a pump or as a turbine. Adjustment is effected by a spindle 22 passing through a hollow rotor-shaft 11 and connected by bevel gearing 20 to the blades 5. The spindle 22, which may be provided with a hand wheel or a servomotor, is supported by bearings 23, 24. The shaft 13 of the lower rotor 14 is journalled in a water-lubricated rubberlined bearing 16. For pump operation, water enters at an inlet 2 and is discharged from a volute 6. For turbine operation, the direction of flow is reversed. The machine may be of axial-flow type and may handle gas or vapour instead of liquid. For example, the recuperation turbine of a compressor plant can operate as a compressor when required.

Filed: 1958-11-28
Abstract: 947,201. Self-propelled missiles and spigot projectors therefor. L V. S. BLACKER. Feb. 29, 1960 [Nov. 28, 1958], No. 38483/58. Headings F3A and F3C. A missile such as described in Specification 773,190 is provided with a member surrounding the tail and attached at its forward end by frangible means to the body of the missile, while at the rear end, the member has a flanged part 38 for co-operation with parts attached to the muzzle of a spigot projector 34. The missile contains a hollow charge fitted with a liner 4 and is surrounded by a detachable unit containing a rocket charge 22 in communication with nozzles 25. The unit carries an annular wing 28 within which two tear-drop shape members 32, Fig. 5, are arranged to tilt about axes radial to the missile, to give directional control. An annular space 24 around the rocket motor contains wires which are payed out during flight, through a gap 26, to convey control signals to the missile. Electric batteries for the controls are housed in a ring 82 within the missile head. Instead of the two members 32, four equi-spaced control surfaces may be provided. The unit-is held in place by a nut 78 screwed on the tail tube 10, and may be removed when the missile is to be fired as a short range projectile, e.g. less than 400 yards range. Riveted to a ring 80 screwed on the motor casing are four fingers 36 extending from the flange 38. Slots 62 between the fingers allow passage of radial vanes 14 carrying a drumshaped stabilizer 12. The flange 38 is received between a plate 42 and a U-shaped plate 46 attached to the projector 34. Spring-loaded plungers 48 bear on the flange to prevent play. Springs 50 may also be used to hold the flange securely, so that the spigot 52 is aligned with a percussion cap 56-of a launching cartridge 58 within the tail tube. Gases from the cartridge serve to re-cock the spigot. The gases also pass through channels 66, 70, 72 to ignite the rocket charge. The passage 66 contains a ball 76 surrounded by black powder ignited by the cartridge and transmitting the flash to the propellant 22. Thereafter the ball moves to close the passage and prevent leakage from the rocket motor or, if the rocket motor is not in place, the ball seals the cartridge. Projecting from the flange 38 is a skirt 64 protecting the stabilizer during handling. The attachment device 36, 38 may be made of welded steel or resin-bonded glass fibre. During burning of the propellant 22, should the pressure become excessive an annular relief passage opens around the nozzle unit 23. Specifications 773,190 and 947,202 are referred to.

Abstract: 845,534. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. Dec. 6, 1957 [Dec. 19, 1956], No. 38749/56. Class 38 (3). In a Ward-Leonard system, the generator G has an exciter 3 provided with a current-limiting field winding 5 which is energized when a current-responsive voltage derived from interpole winding 1 exceeds a reference voltage applied to potentiometer 7. The reference voltage is varied in accordance with the voltage of the generator by means of a magnetic amplifier having a control winding 11 connected to a source of constant voltage, and an opposing winding 12 connected to a voltage divider 13 which is across the generator brushes. A rectifier 14 allows for reversal of the current in the Ward-Leonard circuit. Thus, the value of armature current to which the circuit responds to energize the winding 5 falls progressively with progressive increase of generator voltage. In a modification, three magnetic amplifiers have their output windings connected in delta or star to a three-phase rectifier supplying the potentiometer 7, Fig. 2 (not shown). The magnetic amplifier may be replaced by a D.C. machine in opposition to a rectifier which supplies the potentiometer 7 from an A.C. source. This machine has a field winding connected to the voltage divider 13, a resistor being connected in series with the field winding and providing a voltage in opposition to the voltage obtained from rectifier 14. This arrangement provides that the limiting value of current in the Ward-Leonard circuit will remain constant until the generator voltage reaches a predetermined value, Fig. 3 (not shown). The voltage for controlling the limiting value may be derived from a tachometer generator driven by the motor, Fig. 5 (not shown). The currentlimiting control may be effected by means of the motor excitation instead of the generator excitation, the motor excitation being increased when the armature current is to be reduced.

Abstract: 1,170,316. Purifying liquids by electrodialysis. P. KOLLSMAN. Aug.25, 1967 No.39141/67. Heading C7B. In separating a portion of the solvent from an unsaturated ionic solution by moving by an electric current ions of one polarity and solvent from a first supply compartment through a first membrane into a second solvent product compartment and moving the said ions from this compartment into a third compartment through a second membrane which is preferentially permeable to these ions and of smaller pore size than the first membrane whereby solvent accumulates in the second compartment from which it is withdrawn, all as in Specification 1,001,296, a greater rate of separation is achieved by the modification of maintaining a higher hydrostatic pressure in the supply compartment than in the product compartment. Preferably the pressure in the third compartment also is higher than in the product compartment so as to press the two membranes together. As described the apparatus is closely similar to that of Specification 1, 001, 296 with the difference that the product outlet is below instead of above the supply inlet which is adjustable in level. Modifications are described Fig.8 (not shown) in which annular compartments are employed with a central solvent product outlet pipe, and Figs. 10 to 12 (not shown) a reversible multiple unit cell between electrodes is also described, which cell may include open mesh material of nylon or polyvinylidene chloride to prevent contact between the outermost membranes and the electrodes.
