Title: Phase-locking system for a television signal
IPC: G11B20/02
Filed: 1973-04-24
Abstract: 1434599 Television NIPPON ELECTRIC CO Ltd 24 April 1973 [24 April 1972] 19220/73 Heading H4F  An input composite video signal is phaselocked to a reference signal by sampling and quantizing the input signal in timed relationship with a first clock pulse signal having a predetermined phase relationship with the input signal (e.g. with a pulse signal at three times the colour subcarrier frequency of the input signal), storing the resulting signal samples, reading out the stored signal samples in timed relationship with a second clock pulse signal having a preset phase relationship with the reference signal, and decoding the quantization of the readout stored signal. In the embodiment described a colour video signal from a video tape recorder or a colour video signal received at a central station from a local transmission station is supplied via input terminal 1 to a coder 2, a burst controlled oscillator 3 and a synchronized separator 4. The subcarrier from oscillator 3 is supplied to a clock pulse generator 5 to produce a write-in clock pulse frequency of 10À7 MHz (three times the subcarrier frequency) which is fed to coder 2 and serial-to-parallel converter 6 to produce an 8-bit pulse code modulated video signal which is sequentially stored at the clock pulse rate in memories 7, 8 and 9 under control of write/read switch 12 itself controlled by registers 10 and 11. The memories may each have a capacity of one line or one frame. When one memory is in the write-in state the other two memories are in the read-out state under control of switch 12 itself controlled by registers 16 and 17 in response to reference clock pulses from generator 15. Buffer memories 18, 19 and 20 are coupled to memories 7, 8 and 9 and inhibit gates 21, 22 and 23 prevent the outputs being transferred from the memories 7, 8 and 9 to the AND gates 24, 25, 26 when these memories are in the write-in state. The AND gates are gated by pulses from the register 16 and their outputs combined in OR gate 27 to form the 8-bit encoded video signal of clock frequency 10À7 MHz synchronized with the reference signal. This composite signal is comb filtered 40 to separate the luminance signal component and chrominance subcarrier signal component which are decoded 51 and 52 respectively, the subcarrier of the chrominance component being then replaced by a reference subcarrier in device 60 and combined 70 with the luminance component to provide an output composite video signal.

Abstract: 936,025. Transmission line switching devices. GENERAL ELECTRIC CO. Ltd. June 10, 1960 [June 10, 1959], No. 19948/59. Drawings to Specification. Class 40 (8). In a ferrite switch device the values of magnetic field required for opening and closing the switch are both non-zero, the first of these values being different both from that required for gyromagnetic resonance and that required for imparting zero permeability to the ferrite element. The chosen value is that which gives maximum attenuation of the wave, the attenuation being caused both by absorption and reflection. The non-zero magnetic field value for closing the switch is greater than that required for resonance. The switch may comprise a ferrite element occupying the whole of the space between the inner and outer conductors of a coaxial line. The element is surrounded by a solenoid. A number of such switching elements may be arranged in the branch arms of a turnstile junction, the distances between the switches and the junction being such that energy reflected from the open switches combines at the junction with the input energy and propagates towards a closed switch.

Title: Improved record supporting and releasing spindle for automatic talking machines
Inventor: GUEST LAWRENCE VINCENT
IPC: G11B17/16
Filed: 1957-06-25
Abstract: 818,203. Phonographs &c. BIRMINGHAM SOUND REPRODUCERS Ltd. Aug. 27, 1958 [June 25, 1957], No. 20027/57. Class 40 (2). A centre-post-type gramophone record-changer mechanism has the weight of the stack of records awaiting playing supported by the record-release lever during the time that the lever is releasing the lowermost record for playing. The straight-type centre-post 5 is fixedly mounted to the motor-board 1 together with the boss 8 around which the turntable is mounted (Fig. 2, not shown). The post is recessed 13, providing a horizontal shoulder 6, and is slotted on the side opposite the shoulder so as to accommodate the record-release lever 16. This lever is so shaped as to be movable vertically as well as by rocking to the extent indicated by Figs. 4, 5, 6. Horizontal movement, of the member 21, controlled by the autochange mechanism (not shown) raises and lowers the lever 16 in a controlled manner, whilst the horizontal and vertical components of movement of the upper end of the lever are coordinated by the action of the cross-pin 25 on the inclined surface 24 of a notch 23 in the lever 16. The stack of records awaiting playing 7 rests, during playing of a record, on the shoulder 6, guided by the usual components 27-32. Successive steps in the release of a record are shown in Figs. 4, 5, 6. The diagonal movement of the upper end of the lever 16 up to the Fig. 6 stage ensures that the lowermost record falls freely down the post while the upper edge 22 of the lever prevents the remaining records from following. As the lever is lowered again by the mechanism to the Fig. 4 position, friction between the edge 22 and the new lowermost record in the stack assists in feeding that record into the recess 13. The arrangement of the components 27-32 allows the member 27 to retract into the post when removing the played records.

Abstract: 749,263. Gas turbine plant. MASCHINEFABRIK AUGSBURG-NURNBERG AKT.- GES. July 20, 1953 [July 19, 1952], No. 20115/53. Class 110(3) A gas turbine plant in which the compressed combustion air is heated by the turbine exhaust gases in a heat exchanger before entering a combustion chamber burning gaseous fuel feeding the turbine has an additional combustion chamber in the turbine exhaust duct.between the turbine and heat exchanger to which liquid or gaseous fuel is temporarily fed by automatic means when the load on the plant is increased. In the arrangement shown, air compressed in a compressor 1 is heated in a heat exchanger 3 by the turbine exhaust gases before entering a combustion chamber 5 feeding the turbines 2, 6. The turbine 2 also drives a compressor 4 which feeds fuel gas to the chamber 5. The low pressure turbine 6 drives an electric generator 8. A further auxiliary combustion chamber 7 is arranged between the turbine 1 and the heat exchanger 3. When the load on the turbine 6 increases the 'turbine slows down and the governor 10 acting through a member 9 opens the valve 11. The auxiliary combustion chamber 7 is then put into operation. The temperature of the air leaving the heat exchanger 3 and consequently the temperature of the gases entering the turbine increases and the turbines speed up. More air and combustion gas is compressed and more useful power generated. When steady conditions are again reached, the valve 11 is shut. If a decrease in load occurs, the member 9 opens the valve 12 and reduces the gas supply to the combustion chambers. At starting of the plant, the valves 14 and 15 are closed and valve 12 opened so that the compressor 4 runs in a vacuum. The plant is started by a motor 13. and during thos phase fuel is burnt only in the auxiliary combustion chamber 7. A liquid instead of a gaseous fuel may be used. The. compressors 1 4 may be driven by the low pressure turbine and the generator 13 by the high pressure turbine. A number of air and gas compressors driven by a plurality of turbines may be used.

Title: Improvements in or relating to the manufacture of artificial filaments or threads
IPC: D01D5/04
Filed: 1929-07-02
Abstract: Apparatus for making filaments; cellulose carboxylates and ethers.-Relates to the production of artificial filaments and threads by extruding a solution of cellulose acetate &c. into an evaporative atmosphere and consists in passing the filaments after the formation of a skin-like outer layer thereon into an atmosphere of solvent or other vapour to soften said outer layer and applying a tension to stretch the filaments such tension being wholly or partially confined to that portion of the filaments which has been submitted to the softening influence of the vapour.  Strong filaments of fine or extremely fine denier may be produced.  As shown, filaments 8 are extruded from a line jet 7 into a spinning cell 9, passing thence through a softening chamber 16 and a drying chamber 30 to a cap spinning device 40; in a manner similar to that described in Specification 340,929.  To confine the stretch substantially to the portion of the filaments within the chamber 16, a gate tension device 44 is provided near the bottom of the cell 9.  On starting up, the gate is opened and the thread <PICT:0340930/IV/1> is fed over a smaller diameter roller 36 to impart little or no stretch. Afterwards, the guide 39 is moved to direct the filaments over a conical portion 37 on to a larger diameter 38 and impart stretch, the gate 44 being simultaneously closed through levers 41, 42 and arm 43. The gate 44 may be replaced by a roller which may rotate at a speed equal to or greater than the speed of extrusion so that the filaments may be stretched in the cell 9. To facilitate stretching, plastifiers or high boiling solvents may be added to the spinning solution; thus for cellulose acetate, high boiling solvents such as cyclobutanone, acetyl acetone, diacetone alcohol, dimethyl ethylene glycol, monomethyl or monoethyl ethylene glycols; plasticizers such as methyl or ethyl xylene sulphonamides, or mixtures thereof may be added to the spinning solutions.  Cellulose derivatives include cellulose formate, acetate, propionate and butyrate; methyl, ethyl or benzyl cellulose; or the condensation products of cellulose and glycols and other polyhydric alcohols.  Specifications 165,519, 198,023, 203,092, 277,089, 300,998, 323,790 and 325,233, [all in Class 2 (ii), Cellulose &c.], also are referred to.
