IPC: B60V1/16

Abstract: 1,239,745. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 17 July, 1968 [19 July, 1967], No. 33257/67. Heading B7K. An air cushion vehicle has a flexible skirt wall composed of at least two rows, 25, 12 of contiguous U-section members 17a, 17b of the form disclosed in Specification 1,043,351 arranged concave toward a cushion space 20 so that the inwardly extending side portions 19a of the outer members 17a embrace the inwardly extending side portions 19b of the inner members 17b thereby defining cavities 26 between the rows, the inner members 17b normally projecting below the outer members 17a. Deflection inwardly of a portion of skirt 12 by a surface obstruction produces a first downward pitching moment of force F about the centre of gravity e.g. which in turn propagates further surfaceto-skirt frictional engagement and a rearward shift in the centre of pressure P of the cushion to further increase the downward pitching movement. The resulting vehicle pitch downwards is opposed by pressure air released into the appropriate cavities 26 through either manually or automatically cperated valves 29 mounted in peripherally separated branch pipes 28 to which air induced through an air-intake 13 by a compressor 14 driven by a motor 15 is fed via ducts 16 and 27. Each valve may be operated by means comprising either a spring- loaded rod which upon contact with the surface is moved upwardly to actuate a sensing device to open said valve or a tie cord connected at one end to the lower margin of an inner row member and at its other end to a tension-responsive device, incorporated in a servo-switch, which upon a decrease in the cord tension occurring by member deflection opens the appropriate valve. In another embodiment (Figs. 6 and 7, not shown) each pair of inner and outer members 17b, 17a are normally held in close contact by the pressure cushion air and interconnected by a tie cord/pulley arrangement. Inward deflection of an inner member separates the members to produce a cavity therebetween into which pressure air from the cushion may pass via an aperture in the inner member near its upper margin to form a subsidiary air cushion. The members may be provided at their upper margins with flexible membranes which extend peripherally of the vehicle body and are attached thereto, the said membranes allowing for greater inner member deflection. In a further embodiment (Figs. 10-15, not shown) three rows of U-section members are utilized to form a skirt. A gear-box or pulley system may be incorporated whereby sensitivity to small inward deflections of the inner members is increased.

A method of winding a wire 4 on to a support 1 having a substantially circular cross-section comprises passing the support through clamping means 2, which rotates the support about, its longitudinal axis, and through a non-displaceable winding-means 3, the clamping force of the clamping means 2 being greater than a clamping force of the winding means 3. The support 1 is rotated-by the clamping means 2 so that a wire 4, which is mechanically fixed to the support, is wound on to the support by the winding means 3. The support is displaced axially by the increasing diameter occurring in the winding means and by the common tensile effect occurring because of the introduction of wire for the formation of convolutions 5. The wound body is then rolled by rolls 6 so that the individual wire convolutions are forced into an insulated surface layer of the support and are spaced from one another. More than one wire may be simultaneously wound on to the support.

Abstract: 1,264,067. Fuel injection pumps; regulating I.C. engines. FORD MOTOR CO. Ltd. July 7, 1970, No. 32771/70. Headings F1A and F1B . In a diesel engine fuel injection pump having a plurality of pumping plungers 11 rotatable in unison by a rod 16 to control the point at which their spill ports 17 are opened, each delivery valve 13 is provided with a piston portion 23 of substantial length whereby the ratio of the volume sucked back after valve closure to the delivered volume is between 1 and 1À5. The resulting rapid pressure drop in the delivery line 14 has to be restored during the next injection stroke and hence the commencement of injection is retarded at low speed. Consequently a decreased amount of smoke is emitted. To compensate the fact that retarded injection results in reduced delivery at low speed, the control rod 16 is provided with a spring stop 24. The stop is loaded by a spring 29 and via a lever to the opposing action of a speed governor 28 and a spring 25 connected to a throttle control 27. At low speeds the spring 25 overcomes the spring 29 and allows the control rod to move in a direction to provide an increase in the delivered volume.

Abstract: 1295808 Seals UNITED STIRLING (SWEDEN) AB & CO KB 1 June 1971 18261/71 Heading F2B A seal for a piston-rod of a hot gas engine comprises an element 4 accommodating sealing means 5 (e.g. labyrinth seal) which allows restricted passage of leakage gas from a chamber 1 containing gas at high cyclically-varying pressure to a gas-filled space (e.g. a crank-case), in which the pressure is lower, and a return conduit 6 which returns the leakage gas to the chamber via a non-return valve 7. The pistonrod passes through the element 4 which is sealed to the chamber 1 by an 0-ring which allows radial movements. The element 4 contains the labyrinth seal 5, an 0-ring seal 17, an annular gas space connected to the return conduit 6 and an annular oil-space 10 which is fed with oil from a pump 11 controlled by a switch 16 operable by a magnet 15 mounted on a flexible diaphragm 14. The diaphragm responds to the pressure difference between the gas space and the oil space and ensures a supply of oil at a pressure set above that of the gas space. Oil entering the gas space is drained off through an oil separator 8. The leakage gas is sucked back to the chamber 1 when the cyclic pressure is low below the piston.

Abstract: 1304405 Detecting flaws; SUMITOMO METAL INDUSTRIES Ltd 26 March 1970 [4892/70 Heading G1N Hot-rolled steel bars of round cross-section or pipes are automatically inspected for surface cracks by feeding them longitudinally with rotational movement past at least one sensor comprising an A.C. energized magnet and a pair of differentially acting magneto-sensitive PIN diodes having a recombination region on one side of the I zone connected in a bridge circuit which change resistance in opposite senses in response to magnetic flux leaking from a crack. The diodes are spaced by an amount equal to the width of a typical crack (1-2mm.), thereby achieving enhanced sensitivity (as explained with reference to Fig.3B, not shown). Preferably several bridge circuits are employed with their magnetosensitive diodes arranged in two parallel stainlesssteel-lined grooves in a copper block 16, Figs.7 and 9. Exciting coils 18 are energized at 500H z - 10KH z . The bridge outputs are fed to a selection circuit 34, Fig.17, (not shown), which passes only the signal of largest amplitude. For inspecting long bars, three or four detectors heads are arranged to scan respective thirds or quarters of the length of the bar. A further selection circuit selects only the largest signal from all the heads. Automatic sorting into good, repairable, and scrap, is performed according to the amplitude of this selected signal which is indicative of the depth of the deepest crack in the bar. The detector heads and rollers are spring mounted to accommodate unevenness of the bar. A servo-null system 10, 11, 4, Fig. 5 automatically balances the inputs to amplifier 7 in the absence of a flaw. Details of propulsion and test head suspension In apparatus having three or more detector heads A, B, C, Fig.19, (not shown), drive rollers are arranged opposite the first and last heads and idler rollers Figs.26 and 27, (not shown), are arranged opposite the intermediate head(s).
