Abstract: 459,729. Dynamo-electric machines. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and YOUNGMARK, F. A., Siemens Works, Stafford. July 31, 1935, No. 21738. [Class 35] Cooling ; conductors.- In a high-voltage dynamoelectric machine of the type in which a highvoltage conductor is arranged in the same slot as a conductor of lower voltage in series with it and less heavily insulated from the core the high-voltage conductor is formed with a central conduit through which cooling-fluid may be passed. In the arrangement shown the conduit is formed of two semi-cylindrical tubes 2<a> round which are arranged conducting strands 1 and insulation 6. In a modification the strands are formed to interlock and produce a conduit. The conducting strands themselves may be hollow and contain cooling-fluid. Where a number of coaxial conductors insulated from each other are employed the innermost may be hollow and form the conduit. Suitable cooling liquids are insulating oil, or non-inflammable insulating liquids such as chlorinated diphenyl compounds. The Provisional Specification also describes an arrangement in which a conductor is built up of a plurality of rectangular bars and the cooling fluid is passed through semicircular tubes arranged above the uppermost and below the bottom bar.

Abstract: 1,150,593. Winding slivers. JAMES MACKIE & SONS Ltd. 20 May, 1966 [24 May, 1965], No. 21909/65. Heading D1N. The sliver end of a cross wound sliver ball is automatically tucked into the ball almost tangential to the surface at the point of entry. A sliver ball 1, see also Fig. 1 not shown, is wound by a roller (3) on a spindle (2) and when completed is pushed off the spindle by a plate (13) onto a cradle 20. The winding operation preferably ends with the sliver in a predetermined position along the bobbin and the traversing -guide (5) is stopped just before the winding stops. A knife (15) associated with plate (13) severs the sliver as the ball is doffed and the end hangs free. The free sliver end is guided by a plate (22) and blown by an air jet (23) against a stop (25) so locating its position. Plate (13) is then retracted and brackets 30 raised to lift ball 1 and hold it firm against a plate 21. Alternatively a plate may be lowered to hold the ball. A pneumatic device 28 is then operated to raise a blade 25 which engages the sliver and tucks it into the ball. The blade is then retracted and preferably repeats the tucking action. Brackets 30 then lower the ball onto cradle 20. When the next ball is doffed it pushes the already doffed ball along cradle 20 for removal. In other forms the end may be tucked while still on spindle (2) or the doffed ball may be lowered onto a stationary blade to tuck in the end. The tucking blade may be curved and be moved along a circular arc.

Title: Improvements in or relating to automatic train control systems
IPC: B61L3/12
Filed: 1932-08-16
Abstract: 407,382. Track apparatus for automatic train control. HUDD, A. E., 20, Surbiton Court, Surbiton, Surrey. Aug. 16, 1932, No. 23005. [Class 105.] Automatic train control apparatus comprises a permanent magnet longitudinally disposed along the track and rendered ineffective, under clear signal conditions, by electromagnetic or mechanically operated means which divert the flux away from a train-carried receiver comprising two flux-collecting plates arranged longitudinally so as to be successively energized by both poles of the track magnet, under caution conditions, whereby an armature is moved to effect a warning and braking. Figs. 2 and 3 show in sectional elevation and end view the permanent magnet 10 supported by non-magnetic spacing members 21 in soft-iron cradles 20 attached to the cores 19 of the neutralizing electromagnets 18 ; the assembly is secured by non-magnetic bolts 24 and is mounted on a non-magnetic cast iron base 23. In the arrangement shown in Fig. 6. a magnetic shield 26 carried by arms 27 on an axle 28 is interposed between the train receiver and the permanent magnet 10 by a connection to lever 31 when the signal is cleared. The axle is counterbalanced by a weight 32 and the whole device is enclosed in an aluminium casing. When the track permanent magnet is effective the flux collecting plates 34 of the train-carried receiver, Figs. 9 and 10, direct the flux to polepieces 36 whereby an armature is attracted and removes its turned up spacing lip 40 from between two detent levers 41 which then release a spring-urged plunger 50 in the hollow stem 47 of the brake-pipe venting valve 46 and so permit the valve to open to give an audible signal and a partial brake application. Re-setting is effected by a cable connection 56 which lifts a rod 54 having a lateral member 67 to raise the spring-urged plunger 50 into the position in which it is retained by the detent levers 41 which are then again spaced by the armature lip 40. The rod 54 is recessed at 60 to accommodate in its normal unoperated state one end of a bell crank lever 59, the other end of which actuates the valve stem 47 ; if therefore the rod 54 is wilfully held up the valve 46 remains open. At a danger point, as distinct from a caution point, two longitudinal track permanent magnets are arranged on opposite sides of the centre line of the track and if each is effective two valves are opened thereby giving a full brake application.

Abstract: 442,740. Valve generating circuits. RADIOAKT. - GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Aug. 14, 1934, Nos. 23443 and 23444. Convention dates, Aug. 14, 1933 and Aug. 21, 1933. [Classes 40 (iii) and 40 (v)] The relaxation oscillation generators for the image frequency and line frequency potentials of a cathode ray television system are similar in general arrangement but differ from each other in that the discharge period of the line frequency generator is at least equal to the duration of an image point while the grid circuit of the image frequency generator comprises an additional resistance 20, Fig. 2. In the line frequency oscillator, Fig. 1, the condenser 2 is charged through the circuit 3, 19, 4 ; the resistance 19 is included in the discharge circuit across the thyratron 1 in order to make the discharge time at least equal to or greater than the period of transmission of a single point. The ignition voltage of the tube 1 is raised by increasing the biassing resistance 4 to prevent increase in oscillation frequency due to the condenser 2 not fully discharging. The screen grid potential of the amplifier 9 is such that the exponential curvature of the potentials in circuit 3, 2 is compensated by opposite curvature of the characteristic of valve 9. The inner wall of the envelope of valve 9 has an earthed silver coating to prevent shift of the ignition point. The image frequency oscillator, Fig. 2, dispenses with resistance 19 of Fig. 1 and the grid circuit of the thyratron 1 includes a resistance 20 to prevent arcing at the grid. Synchronizing potentials are applied at terminal 6 in both oscillators and the output to the deflecting plates from terminal 15 should be constructed as a high pass filter.
