Title: Improvements in railway track-circuits signalling systems
Inventor: CHERONNET JEAN
IPC: B61L23/16
Filed: 1957-05-27
Abstract: 855,549. Railway track circuit signalling systems. COMPTEURS ET MOTEURS ASTER. May 27, 1957, No. 16736/57. Class 105. In a railway signalling system employing the track rails for the transmission of signalling current, the ends of a track circuit are connected respectively to a generating device and a receiving device tuned to the same frequency and to respective resonant circuits of the parallel or " wave-trap " type tuned to said frequency and each comprising at least one capacitor and an inductance comprised by a portion of the track. Thus a track-circuit section A without insulated joints, Fig. 10, is supplied by a generator 31 feeding an oscillatng circuit 2 comprised by a short portion 5 of track and a condenser 4 forming a " wave-trap " type circuit short-circuiting the rails at the operating frequency and isolating it from the adjacent track section C. In a similar manner the circuit 3 of capacitor 8 and portion 9 of the track isolates the track section A from section B. A receiver 32 is connected across the circuit 3. Short-circuiting cross-conductors 7 and 10 are connected across the rails 5 and 9, respectively. Entry of a train axle detunes the oscillating circuit and de-excites the receiver. The shortcircuiting cross-conductor instead of being perpendicular to the rails 1 (when so disposed the presence of an axle aligned therewith is without effect) may be disposed obliquely, Fig. 3, or in effect obliquely, Figs. 6-8 (not shown), and Fig. 5, which shows a disposition permitting tamping of the ballast without interfering with the short-circuiting conductor. For track circuit sections of considerable length the section is divided into a plurality of track circuits as in Fig. 10 with inter-circuit relay amplifier stages (Fig. 11, not shown).

IPC: C07C51/12
Filed: 1928-09-01
Abstract: 323,513. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 1, 1928. Divided on 323,475. Right to Patent relinquished. Acids, esters, and other organic oxygen conipounds.-In the production of oxygen compounds from carbon monoxide and alcohols, esters, ethers, or aldehydes in the presence of the catalysts specified in Specifications 254,819 and 320,457, metal halides which are not decomposed under the reaction conditions are added to the catalysts. The halides mentioned are potassium fluoride or iodide, sodium chloride, or aluminium chloride, which may be added to cerium metaphosphate. The process may be effected at ordinary or increased pressure such as 10-500 atmospheres or higher and at 300-400‹ C. Metals which form carbonyte under the working conditions are excluded (as set forth in Specification 286,010) from the catalysts, carriers, gases, or the walls of the reaction vessel, so that coke and graphite, which contain iron, cannot be used as carriers. The walls of this reaction vessel are preferably of special alloys such as an alloy containing 8-10 per cent of aluminium, 1.5-2.5 per cent of silicon or manganese, and the rest copper, or a copper-manganese alloy containing 6-13 per cent of manganese; or a copper alloy containing 6 per cent of silicon and 2.5 per cent of nickel, the nickel in this alloy not being converted into carbonyl under the working conditions. Or the reaction vessel may be lined with chromium-plated or silver-plated or argentiferous material or with glass or the like. In an example a melt of cerium dioxide and phosphoric acid is prepared, and 10 per cent of sodium chloride is added during the operation, the mixture being moulded into blocks; a mixture of carbon monoxide containing 7.5 per cent of alcohol vapour and 2.5 per cent of steam is passed over this catalyst at 360‹ C. at 200 atmospheres pressure, and concentrated propionic acid is produced.

Title: Improvements relating to the vulcanising or like heat treatment of the rubber or other coverings of insulated electric wires

Abstract: 586,209. Electric heating. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and MACDONALD, H. A. Sept. 5, 1944, No. 16916. [Class 39 (iii)] Apparatus for heat treating a non-conductive covering of an electric wire passing therethrough, comprises a first part in which the covering is heated to the treatment temperature in a short period of time by the dielectric loss method, and a second part in which this temperature is maintained for a relatively long period of time by some other method of heating. As shown in the drawing, two tubular electrodes 3, 4 and a tubular chamber 10, e.g., of metal, forming the first and second heating chambers respectively, and the nozzle 16 of an extrusion machine, are axially aligned and separated by short insulating tubes 5, 11, 15. The electrodes 3, 4 are housed in a tubular screen 7 and connected to a high frequency electric source 9. The chamber 10 is heated by the passage of a heavy current from a source 13. An earthed wire 1, emerging from the nozzle 16 with a covering 2, e.g., of natural or synthetic rubber, passes with a small clearance through the aligned members and may be supported at intervals, as by a roller 19 housed in a pocket in the chamber 10. This chamber has an end piece 18 which may constitute a sealing gland for treatments at high pressures. The second heating chamber may be from five to fifteen times the length of the first and may be heated by other means. For example, it may be flooded with, or surrounded by, a heated vapour, or it may be heated by gas flames. It may also be compacted to offer an extended path to the covered wire, such as a helix comprising a number of turns. Specification 554,854 is referred to.
Patent GB-170573-A (GB)
Abstract: 170,573. Bosch Akt.-Ges., R. Oct. 23, 1920, [Convention date]. Interrupters, mechanical; rotary interrupters; timing-devices.-Interrupters for use in hightension ignition systems are arranged so that the time of ignition or break of the primary circuit is adjustable between wide limits without varying the time at which the primary circuit re-closes, by providing means for varying the interval between interruption and re-closure of the primary circuit. This means may consist (Fig. 1) of a rotating cam consisting of two parts 2, 3, the former secured to and the latter angularly adjustable relative to the rotating shaft, the interrupter arm 1 bridging both cam portions. In Fig. 2 two interrupters of the type in which the oscillating interrupter lever is carried on a rotating plate are employed, the two interrupters being connected to parallel. One interrupter has adjustable stationary cams 6 which co-operate with the oscillating lever 7 to interrupt the primary circuit, the other interrupter having non-adjustable stationary cams 5 co-operating with the rotating lever 4, thus effecting a re-closure of the primary circuit at a time independent of the adjustment of the interrupter. In Figs. 3 and 4 the rotating cam is mounted eccentrically by a distance e from the axis of rotation, adjustment of the relative positions of the centres of the cam and cam shaft and of the angular position of the interrupter lever 1 giving a varying time of interruption with a uniform time of re-closure of the primary circuit. In Fig. 5 the interrupter is provided with a stationary earthed contact 8 and an extra insulated contact 10 connected to the primary coil and arranged to move round with the interrupter 1 for timing purposes. A contact plate 9 moves round with the rotating cam 11, and in retarded ignition positions the plate 9 joins contact 10 and 8, producing a uniform time of re-closure of the primary circuit.
