Title: Improvements in or relating to television distribution systems
IPC: H04N7/10
Filed: 1963-03-04
Abstract: 994,233. Television distribution systems. SIEMENS & HALSKE A.G. March 4, 1963 [March 2, 1962], No. 8490/63. Drawings to Specification. Heading H4R. In a distribution system comprising a plurality of stations each of which serves to receive a high frequency television signal and convert it to a lower frequency before distributing it over a local distribution network to a plurality of local substations, unwanted interactions between the signals carried by the different local networks are prevented by means of a synchronizing device which transmits a synchronizing signal for the low-frequency television signals to each station. Thus in one embodiment signals of identical frequencies are transmitted over telephone lines from a central source to each of the stations for use as a mixing frequency so that television signals in Bands IV or V which have been received by these stations may be converted into Band I or III signals which can then be distributed over a conventional distribution network, interference between the signals in the different networks being substantially eliminated as they are all modulated on the same frequency. In an alternative system utilizing a separate local oscillator at each station, the synchronizing device transmits control pulses which ensure that the carrier waves generated at the stations are identical in frequency.

Title: Device for the generation of electric alternating currents by means of non-reacting photo-electric scanning of rotating bodies
IPC: G01M1/22
Filed: 1953-03-28
Abstract: 729,368. Photo-electric control systems. AVERY, Ltd., W. & T. (Schenck Maschinenfabrik Ges., C.). March 28, 1953, No. 8616/53. Addition to 721,856. Class 40 (3). In the arrangement according to the parent Specification, generators 7, 8 were arranged to produce an alternating current output in synchronism with the rotation of an annulus 1, one part of the periphery of which was darkened, so that synchronizing pulses were produced photo-electrically and were amplified and used to drive a synchronous motor driving generators 7, 8. The.load on the synchronous motor was partly taken by means of a motor 10 and a light 14 illuminated by the photo-cell output, enabled the phase of the generators to be compared stroboscopically with that of the photocell pulses by means of a mark 12 on a disc on the shaft of motor 10 and a fixed mark. According to the present invention, the phase of the output of the generators may be displaced relatively to the synchronous motor, e.g. by means of a differential gear between them. Alternatively, field system of either synchronous motor 6 or of generators 7, 8 is arranged to be rotatable and to carry a mark 13a which is compared with the apparent position of mark 12. Thus the phase of the output signals may be brought into agreement with that of the photo-cell pulses and motor 10 may be omitted. It is suggested that synchronous motor 6 may be a hysteresis motor.

Title: Improvements in or relating to electrically operated pumps
IPC: F02M1/00
Filed: 1939-03-17
Abstract: 526,500. Electrically-operated pumps. TECALEMIT, Ltd. March 17, 1939, No. 8627. Convention date. March 18, 1938. [Class 102 (i)] [Also in Groups XXXV and XXXVII] In an electrically-operated pump of the kind in which a diaphragm or piston 1 is operated by an intermittently-energized electromagnet through electrical contacts 21, 26 operated in accordance with the movements of the pumping element, one of the contacts is carried by a resilient member supported at one end from a fixed part of the pump so as normally to maintain the contacts open, and deflected by the movement of the pump element so as to close the contacts and thereafter cause a sliding movement between them, the movable pump element being connected to the resilient member at a point between the contact and the point of support. Two fixed contacts 21 are mounted on a disc 20 of magnetic material fixed to a magnetic casing 10, 11 surrounding a solenoid 6, and coacting contacts 26 are carried by a bifurcated spring 22 secured to a tapered block 25 also mounted on the disc 20. Intermediate its ends the spring 22 carries an armature 27 passing loosely through a hole 20a in the plate 20 and adapted to engage a recess 30 in the core 5 to which the diaphragm 1 is attached. A bolt 29 fixed to the core 5 passes through the armature 27, and a light spring 33 extends between an adjustable head 32 thereon and the spring 22. When the circuit through the solenoid 6 is completed, the core 5 is drawn upwardly against the action of a spring 14 to draw in liquid, and its attraction holds the armature 27 with the contacts 21, 26 closed. This attraction weakens when the armature enters the recess 30 and the spring 33 causes the contacts to separate whereupon the spring 14 causes the diaphragm to move downwardly for the discharge stroke. During this stroke, the spring 33 first brings the contacts 21, 26 together and then bends the spring 22 to cause a relative sliding movement between them. The former 7 of the coil 6 is of highly conductive material so as to damp the induction of the coil when the current is interrupted. If, instead of a solenoid, an electromagnet is used, the damping is effected by a conductive tube situated outside the winding or between the turns and having end discs of similar material.

Abstract: 649,181. Electric discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 1, 1947, No. 8827. Convention date, April 6, 1946. [Class 39 (i)] A low-pressure positive column discharge lamp is provided on the inside or outside surface of the vitreous envelope with a starting strip comprising a composition formed by the reduction of a metallic compound in the presence of a heated fusible vitreous material which upon subsequent cooling closely adheres to the vitreous envelope and contains evenly distributed metallic particles derived from the metallic compound. The fusible vitreous material may be lead borate and the reducible metallic compound may be of the metals in Groups 1 and 8 of the periodic table such as silver oxide, platinum chloride or compounds of gold and rhodium. The reducing agent may be glycerin, citric acid, tartaric acid, polymerized formaldehyde, aluminium formate, sugar or dextrin. A suitable diluent such as methyl alcohol may be added to vary the viscosity of the composition. In an example a paste containing 1050 grams of silver oxide, 600 cubic centimetres of methyl alcohol, 840 cubic centimetres of glycerin and 450 grams of lead borate is used which frits to the glass envelope at temperatures of 500‹ to 550‹ C. which are below the glass fusion point. The resistance of the starting strip is usually 25 to 100 ohms. The composition may be applied to the envelope by painting, squirting or by a thin rubber roller. In the construction shown in the drawing the envelope 2 contains krypton, neon or argon, or mixtures thereof or a vaporizable metal such as mercury or a mixture of a gas and a vaporizable metal. Excess mercury may be present in the drop 9. Electrodes 7 and 8 preferably comprise a coiled coil of tungsten coated with barium and/or strontium oxides. The starting strip 11 may be connected to one or both of the electrodes 7 and 8 and is applied to the envelope before or after the envelope is coated with a phosphor 10.

Abstract: 611,104. Converting; control systems for consumption apparatus. IGRANIC ELECTRIC CO., Ltd. April 10, 1945, No. 8858. Convention date, April 17, 1944. [Classes 38 (ii) and 38 (iv)] [Also in Group XXXVII] For applying current during alternate halfcycles of an A.C. supply 1 through a gaseous discharge tube, such as 3 or 4, to a load, such as the D.C. motor armature 2a, a condenser connected to the grid of the tube is charged through a resistor at a substantially constant rate and is discharged periodically through an auxiliary gaseous discharge tube which is grid controlled by A.C. from the supply 1 and the instant in the half-cycle at which the tube 3 or 4 becomes conducting is varied by changing a bias voltage in the grid circuits. The condensers 25 and 26, connected to the grids 4c and 3c through resistors 29 and 30, are charged, through resistors 28 and 27, by the transformer 11 and the rectifier 15 which apply a voltage across the resistor 22 ; the condensers are alternately discharged through the grid-controlled gaseous discharge tubes 20 and 19. Control voltages are applied to the grids 20c and 19c by the transformer 14 which is fed, through the phase-shifting combination of resistor 12 and condenser 13, from tappings on the transformer 1 which also feed the transformer 11. The grids 3c and 4c are negatively biassed by part of the voltage across the resistor 22. The condenser voltage rises gradually at a substantially constant rate and falls abruptly, so that the grid potential has a saw-tooth waveform; the instant at which the gradually rising grid voltage reaches the ignition value is adjusted by adjusting the biassing voltage by movement of the tapping contact 22a. The method of using and adjusting a saw-tooth waveform of grid voltage is according to Specification 611,105. In a modification, resistance is included in the anode or cathode leads to tubes 19 and 20 so that the condensers discharge gradually. The rate of increase of output current is limited by the increased negative bias applied to the grids 3c and 4c by the condenser 8 which is charged by the series transformer 5 through rectifiers 6 and 9 which prevent the application of a positive charge during decrease of current. The motor field winding 2b is supplied and controlled through an arrangement including grid-controlled gas-filled rectifiers 31 and 32 of which the grids are supplied by a transformer 33 through the phase-shifting combination of the resistors 34 and 36 with a condenser 35.
