Title: Improvements in thermionic valve generators and circuit arrangements therefor
IPC: H03B5/10
Filed: 1926-11-24
Abstract: 262,115. Soc. Francaise Radio Electrique. Nov. 25, 1925, [Convention date]. Addition to 256,653. Thermionic generators, particularly for short waves, are arranged so that the plate, the high and low tension sources, and other bulky apparatus are at earth potential so far as high-frequency currents are concerned, thereby reducing dielectric losses. For the single-valve arrangement shown in Fig. 1, the earthed filament battery 2 is connected to the filament 10 through coils 9 (shown as straight wires). The plate 12 is connected to earth through an ammeter 3 and high-tension source 1, the large shunting-condenser 4 maintaining the plate at zero highfrequency potential. The grid 11 is connected to earth through a coil 9<a> (shown as a straight wire), a high-frequency ammeter 8, a direct-current ammeter 7 and grid-leak 5, the usual condenser 6 being shunted across the elements 5 and 7. In this way all the apparatus except the filament 10, grid 11, and inductances 9, 9<a> carry substantially no high-frequency potentials. The coils 9, 9<a> are tightly coupled and no capacity beyond the interelectrode capacities need be employed. A grid condenser 14 may however be used for increasing the wave-length, or a coil 15 for reducing it. The additional coil 15 may form an extension of the grid coil 9<a>, the grid being connected to an intermediate point of a short-circuited coil. Fig. 4 shows a symmetrical arrangement of two valves. 13, 13<1>. The plates are connected to each other and are earthed through the source 1 shunted by the condenser 4. The filament supply passes from the earthed battery 2 through the coils 9. 9<1> in parallel. The grid circuits comprise the coils 9<a>, 9b and the common grid leak 5 and condenser 6. Points of opposite potential may be used for exciting symmetrical aeriaJs.

Abstract: 325,472. Williams, E. Oct. 18, 1928. T r a c k apparatus actuating signals on trains and for stopping trains. - Signal and control mechanism carried on a train is operated from a sliding table on the track and is so arranged that the signals are operated for a time determined by a rotating fan, and the brakes are applied during that time by an arrestor normally held in the off position by a latch. The end of the spindle of the train apparatus shown in Fig. 1 carries an arm 37 the operation of which from the track rotates cams and gearing to move various controlling arms and slides. For instance, the rotation of the cam 2 operates the sliding shaft 1 against the action of the spring 3<A>, thereby closing the electric circuit through the contact head 6. The slide 1 is returned, when the cam has moved back, by the spring 3<A> and the rotary fan 4 then acts as a delaying device.. During this time the signal 5 is visible and the circuit through the contact 6 remains closed to energize electro-magnets, motordriven signals and visual signals. The visual signals may consist of illuminated rotary discs with transparent insertions or perforations. The apparatus may be locked in its operated position by a spring pressed plate entering a slot in the cam 45; this lock can be released by the driver operating the handle-48. An arrestor 16, Fig. 4, controls the brakes and cuts off the power supply and is normally held in its off position by the latch 19 which can be released by the control arms 28, 30, 34, 38, Fig. 1, or by the electro-magnet 7 energized through the contact 6. The arm 16 is operated by a weight 18 or by a spring 17, which is reset after operation by means of the handle 24.

Title: Improvements in or relating to the doubling or twisting of yarns or threads
IPC: D01H1/10
Filed: 1932-10-31
Abstract: 406,801. Twisting and doubling apparatus for imparting two twists per revolution. SOC. TEXTILE TWISTOK, Clos Montriant, Chamalieres, Puy-de-Dome, France. Oct. 31, 1932, No. 30449. Convention date, July 26. [Class 120 (ii).] In twisting and doubling apparatus for imparting two twists per revolution such as described in Specification 331,702, [Class 120 (ii)], a feeler is pressed against the bobbin or bobbins from which the yarn to be twisted or doubled is drawn and is arranged to operate a stop motion before the yarn is completely withdrawn from a bobbin. This enables, when doubling from several bobbins, the yarn from a new bobbin to be readily connected to that of the nearly exhausted bobbin within the apparatus before its association with the other yarns. When several bobbins are used the yarn from each bobbin is engaged by a feeler adapted to operate the stop-motion ; when the bobbins are mounted in a suspension carrier means are provided to stop the apparatus in the event of the oscillation of the carrier ; and the stop-motion is operated if the tension in any yarn is excessive. As shown, bobbins 2<1>, 2<11>, 2<111> are mounted in a stationary suspension carrier 1, and the yarns are united at an eye and pass as a thread b around a rotary frame constituted by end discs 7, 8 carried by hollow spindles 3, 4 and connected by deformable elements 9, 10 mounted, for example, as described in Specification 406,806. The main switch 15 of a motor 12 which drives the frame 7 .. 10 is controlled by an electromagnet 16 the circuit of which, comprising leads 17, 18, slip rings 42, 43, slip rings 38, 39, leads 57, 58 and leads 34, 35, is closed and the switch 15 opened (1) by detectors 261, 26<11>, 26<111>, normally adapted to bear on the supply bobbins 2<1>, 2<11>, 2<111>, and operable when the bobbins approach exhaustion, (2) by detectors 45<1>, 45<11>, 45<111>, normally supported by the intact yarns, and operable when any single yarn breaks, (3) by a contact 54 actuated by the combined yarns b against the action of a spring 53 when the tension is excessive, as described in Specification 331,702, [Class 120 (ii)], and (4) by a fork 61 adapted to engage the slip rings 38, 39 when the cradle 1 swings, as described in Specification 331,702. The detectors 26<1>, 26<11>, 26<111> are adjustable in length so that they fall, as shown in the case of detector 26<111>, when any desired amount of yarn remains on the bobbin. When the bobbins are wound in close coils, two detectors 26<1>, Fig. 2, may be provided for each bobbin and are arranged at an adjustable distance apart so that when one operates a length of yarn corresponding to such distance remains on the bobbin. If vertically-arranged bobbins are used the feelers are arranged to move in a plane tangential to the last layer of yarn. The electromagnet 16 may be arranged to release a mechanical gear and the driving- motor may be other than an electric motor.
