Abstract: 1460297 Treading or retreading tyres KENTREDDER Ltd 9 Sept 1974 [7 Sept 1973 22 Nov 1973] 42208/73 and 54243/73 Heading B5A [Also in Division B7] A method of applying a tread band or lug to a tyre carcass comprises in either order the two steps of placing a pre-vulcanised tread band or lug on the carcass and shortening at least the ground engaging surface of the band or lug in a direction parallel to the longitudinal axis of the band or lug by exerting a compressive stress in that surface in that direction, the compressive stress being maintained while the band or lug is bonded to the carcass, wherein the steps are such that in the final assembly the ground engaging surface of the band or lug is compressed along its length with respect to its initial non- compressed state and has maintained therein a compressive stress. In one method a lug or an arcuate portion of a tread band having a radius of curvature r<SP>1</SP> is applied to a carcass portion 10 having a larger radius of curvature r. Four such arcuate portions may extend over the whole circumference of the carcass, and each portion or lug preferably includes an inextensible reinforcement along or adjacent its carcass engaging surface. In a further method, a preformed annular tread band and a carcass having an external diameter smaller than the internal diameter of the band are each coated with a bonding agent (e.g. unvulcanized rubber) and the band is applied to the carcass, with a layer of cushion rubber therebetween, by means of pressure applied to the band by an inflatable bag or a clamp. Alternatively the band may be applied to an inextensible breaker of smaller external diameter than the internal diameter of the band prior to application to the carcass. In another method, the annular tread band is formed in one mould and transferred to a smaller mould 21 and the carcass is applied to the tread band in the smaller mould. Alternatively the two moulds may be replaced by a single radially adjustable mould. Pins 8 are placed at the illustrated positions prior to application of the tread band and again prior to the application of the carcass. The presence of the pins is stated to prevent the formation of a large crinkle in each of the tread band and carcass (Fig. 3 not shown).

Abstract: 1532811 Control cf AC motors BRITISH RAILWAYS BOARD 6 April 1976 [14 April 1975] 15224/75 Heading H2J A three phase induction motor 2, fed from an A.C. supply through a D.C. source 1, contactor 5 and inverter 3, is braked by reducing the output of source 1 to zero, opening contactor 5 to cause induction generator operation and closing a contactor 6 to connect the motor to a controlled power-absorbing, unity power factor load 7, whereby real power flows through the load 7 and reactive power through the inverter 3. Thus the inverter rating may be reduced compared with a braking arrangement using a load connected across the D.C. side of the inverter. The load may be a switched resistor chain, a rectifier followed by a controller (e.g. D.C. chopper) connected to a battery to be charged, or a system to feed power back to the A.C. supply. During braking the inverter frequency f is controlled by a feed-back loop 10 responsive to the voltage of the motor or of the D.C. side ofthe inverter to maintain a constant flux density in the motor for producing a desired braking torque, for example maximum torque. To prevent high voltages being applied to the inverter during braking, it is connected to tappings 17, 18, 19 on the motor windings as shown in Fig. 3, the winding terminals 14, 15, 16 being connected to a load in the form of a resistor bank 7 which is progressively reduced, as the motor speed and voltage fall, to maintain the braking torque constant. The tappings 17, 18, 19 may also be used during high speed motoring, the operation for motoring with full winding or tapped winding connections and for braking with trapped winding connections and a tapped, switched-segment resistor 7 being described, Figs. 4(a), (b) and (c) (not shown). Alternatively each winding may comprise two sections connected in series for low speed motoring and in parallel for high speed motoring and braking. Figs. 5(a), (b) and (c) (not shown). Another method is to connect the windings in star for low speed motoring and in mesh for high speed motoring and braking. The loop 10 may be adjusted to obtain a desired braking torque below maximum by varying the constant of proportionality K 1  in the equation f = K 1 V.

Abstract: An arrangement for determining the level in a container includes a capacitive probe disposed in the container, a measuring transducer arranged in the vicinity of the container, and a remote evaluation apparatus. The measuring transducer produces a signal corresponding to the capacitance between the probe and the container. This signal, which is indicative of the level in the container, is transmitted from the transducer to the evaluation apparatus via a two-wire line, which also transmits the current supply DC voltage from the evaluation apparatus to the transducer. The transducer includes a switch for periodically switching from the probe capacitance to a test capacitance. The evaluation apparatus comprises a time control circuit which periodically varies or interrupts the DC voltage on the two-wire line, and the transducer includes a control circuit which responds to the voltage changes to actuate the switch. This permits control of the test operation by the evaluation apparatus over the same two-wire line which also carries the measuring signal and the current supply voltage.
