Title: Improvements in or relating to television and like systems
IPC: H04N5/222
Filed: 1946-05-27
Abstract: 630,855. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 27, 1946, No. 16067. Convention date, May 29, 1945. [Class 40 (iii)] A cathode-ray tube monitor or extension viewer for a television system is synchronized by means of synchronizing signals supplied by the scanning synchronizing tube generators of the transmitter or receiver being monitored. As shown in Fig. 2 the monitor comprises a cathode-ray tube 66, the deflection of the beam 67 of which is controlled by vertical and horizontal saw-tooth wave generators 61, 62 respectively via amplifiers 76 and 74 and deflecting coils 72 and 71 respectively. Synchronizing impulses for the saw-tooth wave generators are supplied by a synchronizing signal separator 58 to which combined vertical and horizontal synchronising signals are supplied from the transmitter or receiver being monitored by means of conductor 40 and amplifier 54. The vision signals to be monitored, together with the appropriate blanking signals, are fed to the intensity control electrode of tube 66 by means of conductor 49 and amplifier 77. Block circuit diagrams of a typical transmitter and receiver showing suitable points to which the conductors 40 and 49 may be connected are illustrated in Figs. 1 and 3 (not shown). The high-voltage for the second anode of the tube 66 may be provided by the unit 78 under the control of the horizontal amplifier 74. The present invention is said to differ from conventional practice in that the synchronizing signals are derived directly from the synchronizing pulse generators of the equipment to be monitored instead of by signals derived directly from the deflection elements of the latter equipment.

Title: Improvements in and relating to elastic fluid turbines
IPC: F01D5/14
Filed: 1944-08-28
Abstract: 596,784. Elastic-fluid turbines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 28, 1944, No. 16256. Convention date, Aug. 27, 1943. Class 110 (iii)] The nozzle and rotor passages of an elasticfluid turbine are shaped so as to ensure pure impulse working. The nozzle blades 45, Fig. 5, are warped to form exit angles increasing from root to tip, and the inner and outer walls 48, 49 form parts of a toroidal shell, the warp of the blades and the curvature of the walls being such as to cause the fluid to leave the nozzle at a velocity which whilst varying in direction is constant in magnitude over the radial depth of the nozzle, thus eliminating radial pressure gradients. The rotor blades 50 are warped to form inlet angles increasing from root to tip at a rate greater than that of the nozzle blade exit angles, the cross-sectional area of flow being constant from inlet to outlet. The exit angles of the rotor blades decrease from root to tip. Each intermediate nozzle passage has the outer wall formed with curvatures 56, 58 to lead the working fluid smoothly to the toroidal exit portion 57, the inner wall being similarly formed. Intermediate nozzle blades 53 are warped similarly to the blades 45 and are precede by an annular channel 59. The toroidal shape of the inner and outer nozzle walls may be approximated by making these surfaces conical, the apieces of the cones being located on the turbine axis. In a modification, Fig. 6, the inner and outer walls 64, 65 of the rotor passages are curved to form continuations of the toroidal surfaces 66, 67 of the walls of the preceding nozzle passages, so as to shorten the intermediate nozzle passages 69.

Abstract: 719,267. Alternators. SELECTRA, Ltd. June 27, 1952 [March 30, 1951], No. 16292/52. Divided out of and Addition to 719,212. Class 35 An alternator is compound excited in dependence on the voltage and current output, and has a separate rectifier circuit for deriving a current for initiating excitation from the residual magnetism. As shown in its simplest single-phase form, the main rectifier F is fed from the secondary winding E2 of a current transformer E in the output line C and an additional voltage generating winding G coaxial with the main generating winding A. The field winding D, which is also connected to the generating windings, is fed from the rectifier F through a controlling rheostat and a solenoid H1 of a relay H controlling the auxiliary excitation circuit. Excitation is initiated at starting by the connection of a second rectifier J through a current limiting resistor K across the main and additional windings A, G by the relay H. As the field current builds up, the relay opens its contacts to put the initiating rectifier out of circuit. A three-phase modification is also described in which the main rectifier is fed from current and voltage transformers from the output lines while the initating rectifier is fed across two lines only, the additional winding being dispensed with.

Filed: 1957-05-23
Abstract: 3, 4-epoxy cyclohexylmethyl-3, 4-epoxy cyclohexane carboxylates or alkyl-substituted derivatives thereof as claimed in Specification 768,157 are converted to heat-hardenable, resinous products by reacting them with a polycarboxylic acid anhydride in amount between 0,1-4,0 mols of anhydride per mol diepoxide.  A poly carboxylic acid or ester thereof containing free carboxyl groups may be used in addition to the anhydride in an amount not greater than 1,0 mol per mol of diepoxide.  Many suitable polycarboxylic acid anhydrides are mentioned.  Lists are also given of the suitable polycarboxylic acids or esters which may be added.  Reaction temperatures are from 50-250 DEG C.  Gelation usually occurs after a period of 5 minutes to 5 hours, but may be hastened by addition in small quantities of accelerators, e.g. acetic acid, sulphuric acid, stannic chloride, perchloric acid, pyridine, aniline, benzyldimethylamine, benzyltrimethylammonium hydroxide or dilute sodium hydroxide.  Curing may be at the same or a higher temperature.  If desired the anhydride or acid may be dissolved to slow down its action to ensure formation of a homogeneous mass before gelling.  Five examples illustrate the preparation of the diepoxides and 53 examples illustrate their curing with various anhydrides, e.g. maleic, phthalic, succinic, poly-adipic, dichloromaleic, tetrahydrophthalic, chlorendic and mixtures thereof, both with and without accelerators, and polycarboxylic acids or acid-terminated polyesters.  Specification 852,410 also is referred to.  Reference has been directed by the Comptroller to Specification 768,157.

Title: Selective halide and sulphide-sensitive electrodes
IPC: G01N27/333
Filed: 1975-04-21
Abstract: The electrode serves to determine the halide ion or sulphide ion concentration or activity in solutions and has at least one solid sensor (11) which comprises two halide and/or sulphide layers and a metal layer disposed between said layers. Furthermore, the electrode has an electrode body (6, 7) enclosing the sensor. Instead of having the form of a membrane, the sensor (4) is in the form of a block with a curved surface but without edges and points, which is the result of shaping the surface of the sensor block by isothermal recrystallisation. The electrode is produced by isothermally recrystallising the surface of the block (4) after mechanical polishing. The part of the surface which is not in contact with the solutions is coated with an elastic layer (5) and mounted in the heated wall of the hollow electrode body (6, 7). Finally, the latter is filled with electrolyte solution (8). <IMAGE>

Title: Method of and arrangement for producing synchronising impulses for television transmitters
IPC: H04N5/067
Filed: 1935-06-06
Abstract: 459,602. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. June 6, 1935, No. 16431. Convention date, June 7, 1934. Addition to 441,761. [Class 40 (iii)] In the parent Specification, the lead connecting the image signal amplifier of a television transmitter to the modulator 15 is earthed through a valve 1 for the period of the synchronizing signals. According to the present invention, the valve 1 is rendered conducting by an impulse derived from a gas-filled glow tube 8, which conducts at a predetermined amplitude of control oscillations and is extinguished independently of the control oscillations. Sinusoidal oscillations 3a, Fig. 3, of line frequency are applied to the grid of the tube 8 which is biassed to conduct at a level P of applied potential. The current passing through the tube charges a condenser 21 as shown in curve 3b, to a valve Q sufficient to quench the discharge. The charge on the condenser then flows away over a resistance 22 in a time approximately equal to the line period. This oscillation 3b is applied over a resistance capacity combination 6, 4, to produce an impulse 3c which is applied to render the valve 1 conducting. Frame frequency oscillations are similarly applied to a tube 9 to produce conductivity of valve 1 at frame frequency. The sinusoidal frame oscillations are preferably obtained from frequency reduction at 10 of the mains frequency of 50 c.s. at 16. The resistance-capacity couplings 6, 4, and 7, 5, have time constants smaller than the duration of the impulses applied to them.
