Title: Railway vehicle braking apparatus
Inventor: MARSH GERALD GRANTON
IPC: B60T8/18
Filed: 1964-08-14
Abstract: 1,035,376. Brakes for railway vehicles. GRESHAM & CRAVEN Ltd. June 22, 1965 [Aug. 14, 1964], No. 33170/64. Heading F2F. A railway vehicle braking apparatus comprises first and second brake cylinders 2, 3; the first brake cylinder 2 being operated in response to pressure in a train pipe 1 and the second brake cylinder 3 being connected to the train pipe via a valve 6 actuated in response to the load on the vehicle, which inter-connects the upper and lower chambers of the second brake cylinder to render it inoperative when the vehicle is unloaded and which connects it to the train pipe for operation together with the first brake cylinder when the vehicle is loaded. As shown, in a vacuum brake the load on a vehicle spring 23 operates the stem of valve 6 through levers 18, 19 and a link 21. The valve 6, Fig. 2 (not shown), comprises three ports 9, 10, 11 connected respectively to pipes 7, 4, 5. In the unloaded condition of the vehicle a spring 26 moves the lever 19, and hence a a valve stem 16, upwards to interrupt fluid connection between the port 9 (connected via pipe 7 to the train pipe 1) and port 11 (connected via pipe 5 to the lower chamber of the second brake cylinder) and to establish fluid connection between the upper and lower chambers of the second brake cylinder. When the vehicle is loaded above a predetermined amount the lever 19 moves downwards against the action of spring 26, moving the valve stem 16 downwards to establish fluid connection between ports 9 and 11, and to interrupt fluid connection between ports 10 and 11 so that the brake cylinder is connected to the train pipe 1 for normal operation. A non-return valve 31, Fig. 3 (not shown), is provided between ports 9 and 11 to permit air to flow from the train pipe into the second brake cylinder to return it to atmospheric pressure when the vehicle is unloaded and disconnected from the train.

Title: Improvements in or relating to electrical conductors for high frequency currents
Inventor: OSWALD THOMAS
IPC: H01B7/30
Filed: 1963-08-23
Abstract: 1,098,921. Cables. SUBMARINE CABLES Ltd. Aug. 14, 1964 [Aug. 23, 1963], No. 33458/63. Heading H1A. The multifilament conductor of a submarine cable consists of Litz-wire stands, or tapes similarly transposed, and is so proportioned as regards the number, size and spacing of the filaments so as to obtain an optimum highfrequency resistance at some specified maximum operating frequency which will give minimum attenuation. A detailed mathematical derivation of the H.F. resistance for a multifilament conductor with an inner tensile core is given, in which the type of conductor without a core appears as a special case when the radius of the core is reduced to zero. The optimum H.F. resistance is found to be a certain factor times a " basic resistance " which is defined in the Specification and is a function only of frequency, filament thickness and the outside diameter of the conductor. The factor is between 2À00 and 1À63: 2À00 for a conductor without a core and 1À63 for the case when the core occupies the whole of the space of the conductor. By optimizing the H.F. resistance the effective temperature coefficient of resistance of the conductor is zero and the variation in group delay is much reduced. In order to transpose the tapes they are grouped around the necessary tensile core in the form of pairs of stacks 21 and 22, each tape in turn being transposed in intervals up one stack, across and down the other. Such pairs of stacks are formed around a plastics or glass fibre cord 25, shown in Fig. 2b, and then laid up on the core. In an alternative method the tapes are wrapped around an adhesive plastics tube which is then flattened and wrapped around the core. Printed circuit, electrolysis and sputtering techniques for forming tapes on an insulating backing are contemplated. The filaments are individually insulated with polyurethane enamel or anodized of aluminium and bonded together at long intervals. They are also impregnated with a viscous liquid or thermo-setting or -plastic resin. The conductor with or without a tensile core of glass, polyethylene terephthalate or polystyrene may form the centre conductor of a coaxial cable the outer conductor of which may have an optimum resistance or be conventional helical tapes or a longitudinal tube, or be with another centre conductor forming a screened pair. An outer sheath may be applied to the cable.

Filed: 1970-07-10
Abstract: 1317165 Aritiskid braking systems ROBERT BOSCH GmbH 10 July 1970 [12 July 1969] 33510/70 Heading F2F [Also in Division G1] In an arrangement whereby vehicle wheel slip, due for example to wheel looking, is detected so that remedial action may be taken, a signal whose frequency is dependent on the angular velocity of the vehicle wheel is derived from a generator 18 which includes a coil 28 whose magnetic circuit includes a wheel 41 rotated simultaneously with the road wheel and having an inhomogeneous periphery. As shown in Fig. 3 the wheel 41 is toothed and co-operates with toothed ends of a core 46 so that the inductance of the coil 28 varies as the wheel rotates. The coil is incorporated in the collector circuit of a transistor 31 arranged to pass constant current, and a varying signal is developed across the coil whose frequency is related to vehicle wheel speed. Sudden change in this frequency is indicative of wheel slip and may be detected in an analyser circuit. The braking system includes a master cylinder 21 and wheel cylinder arrangement 15 which is connected to an analyser 19 receiving signals from the generator 18 and modifying the braking in response thereto.

Title: Methods for producing liquids for flavouring foodstuffs
IPC: A23L27/27
Filed: 1962-09-03
Abstract: 1,014,425. Food preparations. W. HENNING. Sept. 3, 1962, No. 33733/62. Heading A2B. A preparation for food flavouring is obtained by passing wood smoke cleaned by condensation into an aqueous solution, e.g. a 1-2% sodium chloride solution in water, the solution being treated with continuously, freshly-produced, cleaned smoke until an adequate concentration of soluble aromatic smoke constituents is attained. Cleaning of the smoke by condensation removes noxious constituents such as tars, wood vinegar and acetic esters. Insoluble materials of the smoke contain the carcinogenic constituents. A modified procedure for preparing the flavouring, to be added for example in concentrations of 2-20% to salt or fish, is to treat a friable, granular, soluble food such as salt or sugar directly with the smoke until a sufficiently high concentration has been attained, dissolve the sugar, salt or the like, and draw off the solution from insoluble constituents.

Title: Jacketed flexible metallic conduit connector
IPC: F16L33/00
Filed: 1968-07-18
Abstract: 1,206,057. Earth continuity couplings. THOMAS & BETTS CORP. 18 July, 1968 [26 July, 1967], No. 34193/68. Heading H2E. An-earthing ring 50, for use with a connector for a jacketed flexible metallic conduit, comprises two concentric sleeves 52, 56, integral at one end, the inner sleeve 56 extending beyond the end of the outer sleeve 52. A helical rib 62 extends radially outward on the terminal edge of the extending portion of the sleeve 56 and provides a thread for engaging the inner surface of the flexible metallic conduit. The rib 62 enters spaces between the convolutions of the flexible conduit, and provides a locking action, and forms a shoulder to hold tight the adjacent convolution. The rib may be tapered at each end to facilitate engagement. Engagement is not limited to convolutions of a particular pitch, and since the rib is only a single turn, it does not cause the uneven stressing inherent in the conventional thread used in the prior art (Figs. 1, 2, 3, not shown). When assembling the connector, a gland nut 20 is passed over the jacketed conduit, followed by a sealing ring 22, before screwing in of the earthing ring 50. The connector body 36 is passed over the ring and the gland nut 20 is screwed tight over it, so making a moisture tight seal between the sealing ring 22 and the protruding lip 54 on the outer sleeve, and holding the jacketed conduit firmly between the concentric sleeves, so achieving good electrical and mechanical connection.
