Abstract: 476,024. Dielectric guides for displacement waves. STANDARD TELEPHONES & CABLES, Ltd. April 19, 1937, No. 11127. Convention date, May 19, 1936. [Class 40 (v)] A dielectric guide for displacement waves of the order of centimetres is arranged to include secondary-emission or electron-multiplier devices for generating, amplifying, and modulating such waves. Figs. 1 and 1A represent a typical electric displacement wave in which the magnetic lines of force are traced in dotted lines, whilst Figs. 2 and 2A show a typical magnetic wave in which the electric field is indicated in dotted lines. Figs. 1B and 2B show respectively terminal electrodes suitable for handling these two types of wave. The dielectric guide may consist of a lead tube 1, Fig. 18, reinforced by a helical steel spring 2 or by parallel steel wires, and covered internally with a coating, or a tube, or a spiral ribbon of highly-conducting material. In Fig. 5, electric waves passing from guide 1 are modulated or amplified in transit to a second guide O. The cathode C projects a stream of electrons past the input guide I, and by impact on an electrode 1 these produce secondary electrons which are then augmented by electrodes 2, 3, and collected at 5, where they are fed into the guide O. The currents in the terminal wire 6 of the input guide I modulate the electron stream as it passes. Fig. 6 shows a similar secondary-emission device fitted with a set of electrodes o forming an oscillation generator of the Barkhausen or Clavier type. In Fig. 7, incident waves from a dielectric guide 7 are reflected by a curved casing R so as to pass through an opening r where they are modulated by the electron stream from the cathode c and then pass through other secondary - emission electrodes 1, 2, 3. Fig. 9 shows a similar arrangement for handling displacement waves of the magnetic type. Means are also described for generating symmetrical and asymmetrical waves, both of the electric and magnetic type, by means of secondary-emission devices or electron-multipliers, arranged either in parallel or push-pull, and fitted with auxiliary electrodes or diaphragms which operate as focusing devices.

Title: Improvements in and relating to multiple pneumatic distributor valves particularly for the breaking equipment of motor vehicles
IPC: B60T15/04
Filed: 1962-03-26
Abstract: 1,004,831. Fluid-pressure brakes. FABRICA ITALIANA MAGNETI MARELLI S.p.A. March 26, 1962 [March 27, 1961], No. 11514/62. Heading F2F. A multiple pneumatic distributer valve particularly for the braking equipment of motor vehicles has at least some of the seats of the inlet and/or discharge valves of different dimensions. As shown in Fig. 1 compressed air reaches the upper chamber of the three sections A, B, C through conduits 1, 2, 3 via check valves (not shown). Spring loaded shutters 10, 11, 12 co-operate with inlet seats 13, 14, 15 and discharge valve seats formed at the extremity of pushers 22, 23, 24. The shutters are opened by the hollow pushers 22, 23, 24 through springs 19, 20, 21 by a rocker 25 actuated by a lever 26 controlled by the driver. Compressed air is communicated to brake cylinders via conduits 7, 8, 9. The inlet valve seat 14 is of smaller diameter than seats 13, 15 and so due to the reduced pneumatic pressure on the shutter 11 the latter closes after the shutters 10, 12 since the spring loading of the shutters is equal. When the extremities of the pushers move away from their respective shutter the chambers 4, 5, 6 are put into communication with the atmosphere through the axial hole. The discharge valve seats may be similarly dimensioned to give the required sequence of openings. In another embodiment, Fig. 7, wherein a single section of distributer valve is shown the inlet valve seat 33 is formed on a cylindrical element 32 removably held in the distributer valve body D by a cover 35. Compressed air is fed into the section through a nozzle 36 and is controlled by a spring loaded check valve 38. Movement of the shutter 34 from its seat 33 by the pusher 41 allows the compressed air to flow through nozzle 40 to the operating cylinder.

Abstract: 775,931. Automatic synchronizing systems. RADIO CORPORATION OF AMERICA. April 21, 1955 [May 14, 1954], No. 11568/55. Class 38 (4). [Also in Groups XL (b) and XL (c)] In a colour television receiver phase detection of the oscillations generated by the colour oscillator relative to bursts of colour reference carrier is obtained by applying the complete video signal and generated oscillations to separate grids of a single electron tube to an electrode, e.g. anode, of which an operating voltage is applied only during occurrence of the bursts. As shown, the colour oscillator may include part of the phase detector tube. Flyback pulses 68, of duration and timing corresponding to the back porch interval during which the reference carrier bursts are generated, may be applied through a capacitor 70 to the anode of the phase detector tube 65 so that a negative voltage dependent on any deviations from normal phase quadrature of the inputs applied to grids 67, 58 is derived across a resistor 76 connected between the anode and earth. This, applied through a filter 77 or integrating circuit, and a resistor 97 to the grid 58 of the oscillator brings it into phase synchronism. The synchronized colour oscillator may also be separate from the phase detector tube.

[Class 50] Relates to improvements in the starch binder for fuel briquettes described in the parent Specification and comprises a binder prepared by heating to a temperature between 220‹ and 350‹ F. at atmospheric pressure a mixture of starch with water and an alkali such as sodium hydroxide or carbonate, the temperature, time of heating and amount of alkali being proportioned to produce a heavy, viscous, sticky fluid which is added to the fuel before briquetting. The ratio of starch to water may be approximately 1 to 1, but may be altered to about 1 to 3, and the alkali is approximately 2 per cent by weight of the dry starch. The temperature is controlled by use of a pressure vessel. The amount of binder used is such that it forms about to 2 per cent by weight of the dry coal fines. To prevent the growth of mould on the briquettes, an antiseptic ingredient such as copper sulphate or sodium fluoride may be added. A low-volatile strongly coking coal may be added, when coke breeze or petroleum coke fines are employed, to prevent rapid disintegration in a fire. Specification 9932/00, [Class 50], is referred to.

Abstract: 806,659. Pulse generating circuits; phase discriminators. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 16, 1957 [April 19,1956], No. 12011/56. Classes 40 (5) and 40 (6). The invention relates to circuits for producing a train of pulses which occur at times dependent on the phase of an alternating wave in which the alternating wave is squared and then differentiated so as to produce a series of pulses one of which occurs each time the squared wave passes through zero. According to the invention least alternate ones of said pulses are applied to a switching circuit together with a control voltage derived from the squared wave which opens the switch only at and near the time of occurrence of the pulses so that spurious pulses occurring at other times do not reach the output of the switching circuit. The Figures show an arrangement for comparing the phase of two alternating current waves a1 and a2 applied respectively to terminals 1 and 21. These waves are squared in circuits 2 and 22 to produce waves b1 and b2 and differentiated in circuits 14, 15 and 214, 215 to produce trains of pulses b<1>1 and b<1>2 each pulse occurring when the alternating waves pass through zero. These pulses are applied to amplifying valves 12 and 19 and the output of these valves is applied to a switching circuit 16, 18, the negative-going pulse from wave a1 causing the switch to take up one state and the negative-going pulse from a2 causing it to return to the other state so that a pulse train c is obtained in which the width of the pulses and thus the mean current in one of the valves depends upon the spacing of the respective pulses b<1>1 from b<1>2 and thus the relative phases of the two input waves. In order to render the circuit immune from noise, part of the output from the squaring circuit 2 is fed through a capacitor 5 to a Miller integrator circuit 478 to produce a triangular output wave. The tops of this wave are then removed by a diode 13 and the resulting wave is applied to the suppressor grid of 12, so that this valve will conduct only during the flat top of the wave and spurious input pulses occurring at other times will not pass to the output of the valve. Where necessary a similar circuit could be connected in place of valve 19.
