Title: Method and means for synchronising television systems
IPC: H04N5/12
Filed: 1931-11-10
Abstract: 395,373. Converting. HUDEC, E., 17, Potsdamer Strasse, S³dende, Berlin. Nov. 10, 1931, No. 31191. Convention date, Nov. 11, 1930. [Class 38 (ii).] In a system in which controlling impulses are transmitted with impulses of lower amplitude and in which these impulses are separated from the smaller signals by a neutralizing voltage, the control impulse is transformed into a voltage which varies rapidly in one direction when the control impulse is sent and slowly in the opposite direction during the period between the control impulses. In the arrangement shown in Fig. 1, the combined impulses are fed to a rectifier G and with the voltage E neutralizing the smaller voltages the condenser C is only charged by the control impulses, and is slowly 'discharged through a relatively high resistance R. The voltage of the condenser is applied to the grid of a valve in the output circuit of which is a driven motor M. Fig. 4 shows an alternative arrangement applicable to a system employing control impulses of two different frequencies and amplitudes which control the pairs of plates of a cathode-ray tube G1. During the time between the control impulses of the higher frequency the condenser C1 is slowly charged by the saturation current of a valve R1. The control impulse overcomes the neutralizing voltage E1 so that the valve R2 passes current which charges the 'condenser C1 to a voltage at which the neon tube G1 breaks down and effects the discharge of the condenser. Each control impulse of the higher frequency causes a valve R3 to charge slightly a second condenser C2 controlling the second pair of plates of the cathode-ray tube. At the end of a period corresponding to the larger control impulses the neutralizing voltage E is considerably exceeded and the condenser C2 is charged to a voltage such that the neon tube G2 breaks down and discharges the condenser. The arrangement R3, C2, G2 may be replaced by a device similar to R1, C1, G1, R2. The neon tube arrangement of Fig. 4 may be replaced by a device as shown in Fig. 5, incorporating a double-grid valve K and a charging valve L for the condenser C. With little or no charge on the condenser, no current flows in the anode circuit of the valve K1 but a relatively high current passes through the space-charge circuit and applies to the grid G a large negative bias. When the voltage on the condenser C reaches a predetermined value, plate current flows, and with the decrease of the space charge current, the grid G becomes less negative causing an increase in the plate current. If the resistance R is sufficiently large, the plate current flows abruptly and the condenser C is quickly discharged. When the anode voltage has fallen to a lower limit, space-charge current beginsto flow, the anode current is reduced to zero and the condenser is again charged. The control and other voltages in series with the neutralizing voltage may be applied to the grid or plate circuit of the charging valve L, directly to the condenser C, or to the grid or plate circuits of the double-grid valve K.

Abstract: 768,657. Liquid fuel combustion processes. BADISCHE ANILIN- & SODA-FABRIK AKT.-GES. Oct. 29, 1954 [Oct. 31, 1953], No. 31273/54. Addition to 768,656. Class 51 (1). A process for the combustion of combustible substances contained in liquids and liquid combustible substances consists in continuously introducing said liquids into a fluidized layer, kept at combustion temperature, of non-combustible solid particles withdrawing the heat of combustion not required for maintaining the temperature of the layer by heat-absorbing members arranged in touch with the layer. " Black liquor " may be consumed by the process the fluidized layer comprising a rock material of silicate nature kept at 850‹ C. by cooling pipes arranged in the layer and through which flows water boiling under pressure. The combustion gases remove the " liquor " residue as flue ash which is precipitated in a waste heat boiler in the form of fine grains. When burning fuel oil the fluidized layer may comprise chamotte grains. The combustion of the " black liquor " may be carried out in a layer of the residue formed by the combustion or a mixture of the solid particles and the residue.

IPC: B64D37/16
Filed: 1965-07-22
Abstract: 1,105,823. Valves. DOWTY ROTOL Ltd. July 7, 1966 [July 22, 1965], No. 31286/65. Heading G3H. [Also in Division F1] A fluid-flow proportioning device e. g. as used for supplying fuel to a gas turbine engine of an aircraft comprises two or more tanks 23, 24, two or more pairs of sliding vane metering-devices 12, 13 and 16, 17 each pair being driven by an hydraulic motor 15, 18 of the swash-plate type, and a manifold 35 with outlets 36 and 37 supplying the normal and augmented thrust requirements of the engine whilst an additional outlet 38 is provided for de-fuelling. The supply of normal fuel to the outlet 37 is effected by devices 12, 13 drawing from tanks 23, 24, respectively, in proportion to the capacity of the devices. Upon failure of the motor or one of the devices fuel flows through by-pass passages 39 or 40 into the manifold 35. Should a line 25 break or tank 23 empties first the same torque is applied to the device 13 as when both devices are functioning normally so that a higher pressure is produced in the manifold which opens a blow-off valve 46 to supply fuel to the device 12 for lubrication purposes. The same effect is realised by another blow-off valve 45 should the same fault or faults occur with the other tank. Thrust augmentation is obtained by operating the motor 18 so that the manifold receives fuel at a higher rate; the associated devices 16, 17 are subjected to the same emergency lubrication service as the other devices 12, 13. The control of motor 18 may be automatic or manual and the outlet 37 may lead to lift engines instead of being used for thrust augmentation. All the lines leading into the manifold from the metering devices incorporate one-way valves 47-50 and the passages 39, 40 include a by-pass valve 41 or 42. Each tank may house a boost pump 51, 52, the delivery of which is regulated by means in the manifold sensitive to the fuel demand of the engine or engines.

Vacuum tubes. - A discharge device is provided with a cathode heated by conduction from a filamentary resistance; the niaments may be spirally coiled and the cathode is connected in series therewith and two such resistances may be employed, the cathode being of such cross section that there is substantially no potential drop along its length. The invention is described with reference to a valve wherein a cylindrical anode 3 is supported from the pinch by a wire 2 and encloses a spiral grid 5 carried by a wire 4. Within the grid is the cathode consisting of an oxide coated nickel tube 6 to each end of which is welded a tungsten spiral 7, the lower spiral being connected to a lead 8 and the upper supported by a wire 9 connected to a lead 10. The wire 9 is stayed from the wires 2, 4 by wires 11, 12 and a glass rod 13. In operation, alternating current may be applied to the resistances and to a potentiometer in parallel therewith, the grid being connected to the potentiometer. Alternatively, the grid may be connected with the cathode by a wire which may also serve as a cathode support. In a modification, the coiled resistances may be formed in V-shape, the point of a V being connected to each end of the cathode and the free ends to support wires. In this case, the planes of the V's are arranged at right angles. The valve may also be used as a detector.

Filed: 1945-11-22
Abstract: 594,282. Domestic grates. DUNN, W. E. Nov. 22, 1945, No. 31448. [Class 126] A boiler of the kind wherein the fuel is contained within a hopper the lower end of which discharges on to a grate, with one or more passages extending from adjacent the grate to near the upper end of the hopper, so that air or hot gases may pass through said tubes without passing through the whole mass of fuel, has two dampers, one adapted to close the upper end of the hopper and the other adapted to close the said passage or passages, the two dampers being adapted to move into open or inoperative positions and being superimposed or lying in parallel planes, when closed. The invention is shown applied to open fireplaces of the type described in Specifications 578,581, 581,301 and 594,280, the dampers 12 and 13, Fig. 1, closing the hopper 4 and the passages 11 respectively. A square-sectioned rod 19, Fig. 4, engages loosely with a square hole in the hinge sleeve 16 of the large damper 13 and a rod 18 passes through all the hinge knuckles, but engages loosely with square holes in the hinge knuckles 14 of the smaller damper 12, the loose fit in both cases giving a certain amount of play assisting effective seating of the dampers. The two rods 18 and 19 are moved independently by bars 27 and 28 respectively, the actuating mechanism, described in Specification 594,279 being housed in side cheeks 29. Fig. 6 (not shown), depicts a thermostat allowing automatic control of damper 13 for small movements near the closed position, within the limits of the aforementioned play on the rod 19.

Abstract: 1425968 Automatic winding of wire spools PRODUCTIONS SARCEM SA 2 July 1973 [18 July 1972] 31465/73 Heading D1J A spool of wire is automatically wound by a machine that is programmed to (a) secure the wire to be wound in a clamping device rotating with the spindle on which the wire is to be wound; (b) make one revolution of the spindle before the wire is moved to a traverse zone; (c) cause the spindle to rotate for a predetermined number of revolutions; (d) open the clamping device; (e) move the wire being wound back towards said clamping device: (f) cause the wire already in the clamping device to be extracted from, and the wire extending from the supply to be placed in, said clamping device; and (g) close the clamping device on the wire extending from the supply and cut the wire leading from the clamp to the spool. The spool is then automatically doffed. In Fig. 3 the spool is wound between two cheeks 6, 9. Cheek 6 is rigid with a core 5 that extends into and is driven by cheek 9. At the start of a winding operation the wire extending from the supply is clamped between a clamp and a cam 14 rotating with the cheek 9. When one revolution of the core 5 has been made the wire is moved via a helicoidal slot 23, to a traverse member 7 that traverse the wire between the cheeks 6, 9 during a predetermined number of revolutions of the core 5. Thereafter the clamping action on the wire is released and the wire being wound is moved back to the clamping device via a cut out 15, Fig. 4, in the cam 14. At the same time an extractor 25, Fig. 4, is moved into the path of the wire extending between the helicoidal slot 23 and the wound spool and this causes the initially clamped end to be removed from the clamp. The clamp then closes on the wire extending from the supply. The wire between the clamp and the finished spool is automatically cut and the cheeks 6, 9 move apart to doff the spool.

Abstract: 286,794. Mond, A. L., (I. G. Farbenindustrie Akt.-Ges.). Dec. 11, 1926. Purifying fats and fatty acids; soaps, processes for making.-Fatty substances of vegetable and animal origin are bleached by the in conjunction, of one or more inorganic non-gaseous oxidizing agents, such as permanganate, chlorate, or hypochlorite, and one or more inorganic agents acting by reduction or by adsorption, such as nascent hydrogen or bleaching earths. Prior to being bleached, the substance may be carbonized with concentrated sulphuric acid, or made into an emulsion with the aid of soap, and during the bleaching an amount of acid at least equivalent to the alkali in the permanganate, chromate, or chlorate employed, may be added. After being bleached, the substance may be transformed into soap which is then bleached with hypochlorite. In examples :-Ground nut oil is treated with permanganate and chlorate in presence of sulphuric acid and then with nascent hydrogen produced by the addition of zinc dust. aluminium, &c. Soya bean oil fatty acid, neutral or acid plant oils, or maize oil may be similarly bleached. Rape seed oil is treated with a bleaching earth and sodium hypochlorite; ground nut oil is bleached with active carbon and permanganate in presence of sulphuric acid ; rape seed oil is bleached with active carbon and hypochlorite; tallow, slaughterhouse fat, palm kernel oil or the corresponding fatty acids, bleached as above described, are transformed into a sodium soap and then treated with hypochlorlte, or are transformed into a potassium soap, chlorine being introduced into the mixture during the transformation to produce the necessary hypochlorite.

Headings H3B, H3P and H3T. A matrix of loads 1-9, Fig. 1, which may be magnetic storage cores, has row and column wires arranged in pairs, and a single load is selectively energized over individual rectifiers 10-13 by closing one row and one column switch in the groups 14-16 and 17-19 to initially select the load, followed by opening a normally closed switch 25 or 24 to pass current from a constant current source 26 or 27 through the load in a desired direction. Preferably the D.C. source concerned, e.g. source 27, is activated before the associated normally-closed contact 25 is opened. In a modification, Fig. 3, the rectifiers 10-13 associated with each load are replaced by a transformer having two primary windings 30, 31 wound in opposite directions and a secondary winding connected to a load 29. Each primary winding is connected between a different row and column wire of the wire pairs through a respective rectifier 32, 33, the circuit being otherwise the same as previously described. All the switches may comprise valves, or transistors as shown in Fig. 4 in which NPN transistor switches 14-19 are controlled by address register inputs 34- 36. The normally closed switches 24 and 25 also comprise transistors which have a small negative emitter potential to avoid interaction with transistors 14-19. A read or a write operation is effected by applying a pulse to an appropriate terminal 37 or 38, this pulse switching off a transistor 24 or 25 and activating the relevant constant current source 27 or 26. Details of the normally closed switches 24, 25 and sources 26, 27 are shown in Fig. 5. Each constant current source comprises a series resistor 29, and transistors 40, 43 which are respectively conductive when a read terminal 38 or write terminal 37 is pulsed. The change of voltage across resistor 39 cuts off the current through the transistor switch 24 or 25, the action being slowed by a delay circuit 41, 44. Since the delay circuits each include a shunt rectifier, there is no delay in reclosure of switch 24 or 25 when the pulse at 37 or 38 terminates. Further rectifiers 46, 47 are connected between the inputs of each switch 24, 25 and the outputs of the opposite constant current source which enable voltages induced by the load to be absorbed when the read or write pulse terminates.
