Title: Improvements in or relating to electric circuit interrupters
IPC: H01H33/70
Filed: 1954-02-19
Abstract: 740,031. Gas-blast switches. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Feb. 19, 1954 [Feb. 26, 1953], No. 4900/54. Class 38(5) In a gas-blast switch, valve means 23 alternately connect high and low pressure reservoirs 5, 6 to an insulating column 7 supporting an interrupter unit 10, the high pressure reservoir 5 supplying high pressure gas through the column 7 past the interrupter contacts 47, 49 into a, regurgitation chamber 19 to open the contacts and extinguish the arc, and the low pressure reservoir 6 being connected to the column 7 so that high pressure gas accumulated in the chamber 19 can flow back past the contacts, through the column and into the reservoir 6 when the contacts close. The valve means 23 comprises valve discs 28, 29 secured to a rod 30 which is moved by a bellows 35 against the bias of a spring 36 into the position shown when high pressure gas is supplied through a pilot valve 40 from the reservoir 5. the reservoir 5 being connected to the column 7. On the operation of the valve 40 by means of a solenoid (not shown) the bellows 35 is connected to the reservoir 6 so that the high pressure gas within it is exhausted and the spring 36 moves the rod 30 to close the valve disc 28 and open the disc 29 to connect the low pressure reservoir 6 to the column 7. In Fig. 4 the column 7 supports two seriallyconnected interrupter units 10 each shunted by an impedance unit 13 supported between the associated chamber 19 and a brace 11 which inter-connects the impedance units and the support 8 for the fixed contacts 47. Each movable contact 49, Fig. 6 is hollow and is provided with vents 52 opening into the chamber 19. When high pressure gas is applied, it acts on a piston 50 which moves in a cylinder 51 to open the contacts, the cylinder being vented by a spring-loaded valve 56. Alternatively, each moving contact may be opened by a bellows against the bias of a spring as pressure starts to build up in the regurgitation chamber, Fig. 7 (not shown). After each pair of the contacts 47, 49 has been opened and the arc extinguished, the pressure built up in the associated impedance unit 13 by pressure gas acting through a. small conduit 63 is sufficient to compress a bellows 68 against the bias of a spring 69. This moves a contact 67 carried by the bellows away from a fixed contact 64 carried by the impedance element 65 and interrupts the residual current through the impedance unit. A compressor 9 is provided to recompress some of the gas in the reservoir 6 and restore it to the reservoir 5. Thus the switch has a closed gas system and may utilize sulphur hexafluoride. Reference has been directed by the Comptroller to Speciftcation 736,090.

Title: Improvements relating to tuneable reactance amplifiers
IPC: H03F7/04
Filed: 1964-02-05
Abstract: 1,005,031. Parametric amplifiers. NORTHERN ELECTRIC CO. Ltd. Feb. 5, 1964 [Feb. 15, 1963], No. 4912/64. Heading H3B. A parametric amplifier using either the up or down converter mode of operation is tuned over a range of approximately Œ20% of a reference signal frequency fs in a coaxial line 7, Fig. 1, the signal frequency being applied to a semi-conductor varactor diode 1 located in a waveguide having a pumping frequency fp at input 5 and an output frequency fi at output 6, the waveguide including tuning elements 14, 15 and 17 which respectively match the susceptance, conductance and admittance of the waveguide and the diode. The mode of operation is determined by a band pass filter 16 which passes either the lower side-band (fp - fs) or the upper sideband (fp+fs) to the output as the case may be. Tuning element 14 acts as a short-circuit at the selected sideband frequency to offset the susceptance of the diode and also acts as a bandpass filter for the pump frequency. The second tuning element 15 is positioned in the waveguide so as to cancel out the conductance mismatch of the diode to the waveguide, while the third tuning element 17 is in a region of open-circuit relative to the short-circuit of element 14 and reduces the mismatch which occurs if the signal frequency and hence the selected output frequency varies in the specified range. As shown, a capacitive element 17 is used which includes a capacitive screw; this element may be replaced by an inductive iris as is used for filter 15. Likewise the filter 15 may be replaced by a capacitive screw. In a modification, Fig. 3, a common input-output port 5 is used, the bandpass filter 16 consisting of an adjustable shortcircuit 16a. In both embodiments the coaxial signal line 7 includes an R.F. choke for blocking the pump and sideband frequencies and is matched by an adjustable low impedance sleeve 12 serving as an impedance transformer.

Patent GB-720750-A (GB)
Title: Improvements in or relating to the sealing of mounts in glass or vitreous bulbs for electric lamps, electronic tubes and like evacuated electrical devices
IPC: H01J5/24
Filed: 1953-02-24
Abstract: 720,750. Making electric lamps &c. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Feb. 24, 1953 [April 21, 1952]. No. 5113/53. Class 39 (2). In annealing the glass bulbs for evacuated electrical devices, such as electric lamps or electronic tubes, after sealing mounts thereto, a bulb and a mount supported initially on separate and relatively, movable supports are sealed together and, after the sealing operation, the bulb is raised from contact with its locating support or holder and, with the mount sealed thereto, heated uniformly to the annealing temperature. In the example the lamps are annealed while carried in a lamp-making machine of the turret type provided with sixteen heads which are indexed through a corresponding number of stations. Each head 10 comprises a journal 22 supporting a pair of vertical rods 44, 46 carrying a bulb holder 48 provided with inwardly directed radial fingers 50 upon which a bulb 52 is placed on arrival at station 3 and the lower part of the journal has secured to it a belt-driven pulley 24 whereby the head 10 is rotated relative to the turret table 12. A lamp mount 33 comprising an exhausting tube and leading-in wires is inserted while the head is at either station 1 or 2, into a hollow sealing pin 32 at the upper end of a sealing shaft 20 which is keyed to the journal 22 and can also be raised relative to the bulb support when its lower end 30 engages a stationary cam track 16. The mount is thus positioned within the bulb at station 4 and the two are rotated together and subjected to preheating, shaping and sealing by gas fires at stations 5 to 8. Further heating is applied at station 9 and air is blown upwardly through the shaft 20 to prevent the bulb cullet from collapsing on to the sealing pin 32. At station 10 the cullet is cut off and drops from the sealed lamp, and at station 11 a jet directs cooling air on to the sealed area. Annealing commences at station 12 when the lamp is lifted from the fingers 50, as shown in Fig. 7, to enable a burner 58 to direct a flame upwardly against the sealed portions of the rotating lamp. The annealing is continued by a downwardly directed burner 60, Fig. 8, at station 13, after which the lamp is allowed to cool uniformly in the atmosphere until discharged at station 16.

Title: Improvements in alternating current generators
IPC: H03B5/30
Filed: 1931-02-20
Abstract: 378,923. Oscillating machines. WALTON, G. W., 2, Dean Street, Soho, London. Feb. 20, 1931, No. 5427. [Class 35.] A generator of electrical oscillations comprises a motor portion maintained in vibration by impressed oscillations, and mechanically coupled thereto, a generator portion operating by virtue of the relative movement of an electrical conductor and a magnetic field which is substantially constant, or at least independent of the vibratory motion. The invention is concerned more particularly with machines producing constant low frequencies of accurate sinusoidal wave form for use in television systems. A casing in two parts 1, 2 carries cores 4 on which are wound coils 5. The ends of the cores carry discs 6 to which are attached sleeves 7 surrounding the coils 5. The parts 1, 2, 4, 6, 7 are of magnetic material. In the air gaps between the sleeves 7 and the casings 1, 2 are cylindrical metal shells 8, 9 connected by a rod 10. The rod may be in two parts to permit separation of the cylinders 8, 9. The cylinders carry pivot pins 11, 12 engaging in jewelled bearings carried by adjustable rods 13, 14 and are provided with spiral springs 15, 16 of opposite hand secured at their outer ends to the cylinders and at their inner ends to insulating collars 17. Additional springs 20, 21 also of opposite hand may be provided between the cylinders. Electrical connection with the cylinder 8 of the motor portion is made by means of the terminal 18 connected to the spring 15, and the casing 1, 2, and the cylinder 9 of the generator portion is similarly connected by means of the terminal 19 and the casing. The outer ends of the springs 20, 21 may be connected to insulated terminals. When alternating current is passed from one end of the cylinder to the other, the coils 5 being energized, the system oscillates and currents are generated in the cylinder 9. The cylinders 8, 9 and the rod 10 constitute a lumped mass, and the springs a lumped compliance whereby the wave form of the generated current approximates closely to a true sine wave and the frequency is substantially independent of the amplitude of the oscillations over a substantial range of amplitude. Fig. 3 shows a system of connections which may be employed. The electrical oscillations generated in the cylinder 9 are fed through a transformer 23 to a thermionic valve amplifier V1, V2, V3. Suitable potentials are applied to various parts by a potentiometer 22 connected to a continuous current source 26. The valve heaters are energized from an alternating current source 27. The output is obtained at the terminal 25 from which a certain amount of energy is applied by the motor cylinder 8 through a transformer 24. Small adjustments of the natural frequency of vibration of the system may be effected by relative rotation of the casing parts 1, 2. In a modification, the moving conductors are in the form of discs.
