A needled fabric structure comprises at least two layers 12, 14 of fibres and a foundation 10 of synthetic material sandwiched between the layers 12, 14, the foundation having been permanently stretched in a warp-wise direction. The foundation may be either a scrim, i.e. a loosely woven fabric, or a warp of spaced apart yarns and may be made of polypropylene, nylon, cellulose acetate, acrylic, polyethylene, irradiated polyethylene or polyester fibres. The layers 12, 14 comprise batts which may be made of rayon, nylon, acrylic, wool or cotton fibres or a mixture thereof and which may be fed from carding machines or from rolls and are folded so that the fibres extend generally cross-wise to the feed direction. The fibres of the batts 12, 14 are needled into the foundation 10 by a needle loom 16 which may be of the type described in Specification 923, 762. The needled product passes between feed rollers 18, is subjected to heat by a suitable source 22 and passes between rollers 20 which are driven at a higher speed than the rollers 18 to stretch the warp of the foundation 10. This warp is maintained in a stretched condition for a sufficient length of time to allow for cooling and permanent setting thereof. In a modification, Fig. 3, the warp of the foundation 10 is plasticized by a solvent and/ or heat, the solvent being contained in a tank 32. The tank may be closed by a cover 33 and sealed for pressure operation when heat is used as the plasticizer. In a further modification, Fig. 4 (not shown), the foundation 10 is plasticized by a solvent sprayed on to the fabric, excess solvent being collected in a tank and re-used.

Title: Frequency modulated transmitter monitor
Inventor: GARFIELD WILLIAM LITTERY
IPC: G01R29/06
Filed: 1962-10-04
Abstract: 978, 727. Frequency; modulation measurements. STANDARD TELEPHONES & CABLES Ltd. Oct. 4, 1962, No. 37526/62. Drawings to Specification. Heading G1U. [Also in Division H4] A radar or radio altimeter FM signal is adjusted in frequency sweep or the tuning of a resonator or tuned circuit adjusted until the maximum or minimum frequency of the sweep coincides with that of the resonator or tuned circuit as shown by a train of single and not double pulses appearing after detection on an oscilloscope during the time base scan. The FM signal is then amplitude modulated by an oscillator of frequency equal to the frequency sweep so that an additional train of single pulses appears exactly mid-way between the first pulses and not double pulses as would happen if the modulating frequency of the oscillator was too low. The oscillator frequency may be adjusted until this happens so that either this frequency or the frequency scan can be measured or set up in terms of the other. Alternatively, the modulating frequency can be one half the frequency sweep and the resonator tuned to the maximum or minimum frequency of the sidebands produced by modulation, so that four equally spaced pulses are produced, or two if a carrier suppressing balanced modulator is used. The balanced modulator may be a strip-line hybrid ring junction.

Title: Method of forming a fluid-tight barrier in an electric cable
IPC: H01B7/288
Filed: 1972-08-11
Abstract: 1379294 Cable moisture barrier CABLES DE LYON-ALSACIENNE-GEOFFROY DELORE 11 Aug 1972 [13 Aug 1971] 37663/72 Heading H1A A process for the manufacture of a fluid-tight barrier for an electric cable consists in filling the interstices of the cable with a pulverulent product of grain size of 100-150 microns which swells on contact with water, thus forming a fluid-tight plug if the outer sheath is punctured, the product being sprayed on at the same time as the core of the cable is laid up, and being electrostatically attracted by the conductors of the core, which are connected to earth, while the pulverulent product is fed from an insulated tank, at high voltage. To prevent disturbance of the homogeneous layer of pulverulent during tests which involve subjecting the cable to high gas pressure, crepe paper is disposed into the cable interstices between the conductors. The invention is applicable to coaxial pair homogeneous telecommunication cables.

Title: Clutch with tiltable plated and inclined face
Inventor: HUMPHREY ROBERT P
IPC: F16D19/00
Filed: 1957-12-09
Abstract: 832,029. Positive clutches. GENERAL GAS LIGHT CO. Dec. 9, 1957, No. 38240/57. Class 80 (2). Relative axial movement of coaxial driving and driven clutch members causes an inclined surface on one member to tilt a clutch part, drivingly connected with the other member, to produce abutting contact between flat surfaces for clutch engagement. A driving pulley 1 is rotatably mounted on a driven shaft 2 by a bearing 6 held against axial movement by a spring ring 7. The shaft carries rigid therewith a cap 10, the outer surface having axially extending parallel surfaces 12 terminating in axially inclined shoulders 13. An annular clutch ring 15 supported on the cap 10 has interior surfaces which drivingly engage the flats 12, the bore of the ring being oppositely chamfered at 17 to allow tilting of the ring against a deformable rubber ring 20 backed by a washer 21 abutting the bearing 6. The ring 15 is prevented from axial movement away from the shaft 2 by a spring ring 18 (Fig. 2, not shown) in a groove 14 in the cap 10. The pulley 1 is formed with an axially extending boss 5 forming a chamber 8 in which is slidably mounted a piston 22 having an inclined end face 26, the piston being prevented from rotation relative to the chamber 8 by a screw 25 engaging a slot 24 in the piston. The end of the chamber 8 is closed by a plate 28 carrying a rotating seal 29 for a pressure fluid inlet pipe 31 having an outlet port 32. Admission of pressure fluid behind the piston 22 causes the piston to move axially and the face 26 to contact the ring 15 which tilts against the rubber ring 20 until the face 26 and the adjacent face of the ring 15 are abutting for full clutch engagement. In modifications, the piston 22 may be moved axially by electrical or mechanical means, and the rubber ring 20 may be omitted.

Title: Process for increasing the critical current density of layers of superconducting intermetallic compounds with ª-tungsten crystal structure by particle irradiation
IPC: H01L39/00
Filed: 1966-08-30
Abstract: 1094570 Super-conductors SIEMENSSCHUCKERTWERKE AG 30 Aug 1966 [7 April 1966] 38717/66 Headings H1A A5 and A4D The critical current of layers of a superconducting intermetallic compounds with # tungsten crystal structure such as niobium-tin, is increased by irradiating with protons. Other suitable intermetallic compounds are those containing niobium, vanadium or tantalum such as Ta 3 Sn, Nb 3 Ga, Nb 3 Al, V 3 Ga, V 3 Si, and V 3 Sn. In one embodiment a niobium tube is coated with a 4Á thick layer of tin and heated to effect diffusion to provide a 7Á layer of Nb 3 Sn on the tube. The tube 25, Fig. 2, is placed on a copper holder 26 in the irradiation chamber of a 3Mev Van de Graaff accelorator which provides a scanning beam of protons 5. The copper tube 26 is totated at one r.p.m. and cooled by forced air on to fins 29. The protons are captured by Faraday cage 33 and current integrator 34 makes it possible to determine the total time integrated proton flux applied to the tube. The arrangement may be such that the protons completely penetrate the layer to provide a homogeneous distribution of lattice defects which increase the critical current, or penetration may be only partial resulting in a sharp maximum in the number of defects at the limit of penetration. There is an optimum range of integrated proton flux which increases with increase of mean proton energy in the layer. Reference is made to known treatment of Nb 3 Sn by neutron bombardment in a nuclear reactor. In a further embodiment, the  proton beam is applied to a niobium ribbon bearing a Nb3Sn layer mounted on a copper holder cooled with liquid nitrogen. The resulting superconductor may be used to provide high magnetic fields or as a magnetic shield.

Abstract: 1,035,489. Seals; hydraulic shock-absorbers. W. K. WASDELL. Oct. 10, 1963 [Oct. 13, 1962], No. 38840/62. Headings F2B and F2S. A piston-rod seal, such as for hydraulic shockabsorbers, comprises a rigid guide ring 3 mounted at the mouth of the cylinder 1, a flexible sealing ring 12. interengaging tongues 8, 10 and recesses for retaining connection between the radially-outermost parts of the two rings, and a sealing lip 13 projecting axially from the ring 12 towards the piston 6 and engaging the rod. Preferably, the flexible ring 12 is made of synthetic rubber and provided with an additional sealing lip 14 for engaging the cylinder wall, and a rebound stop 15 for the piston. The guide ring 3, which may be screwed or pressed into the cylinder or held, as shown, by an inturned rim 16, is made of a bearing material such as porous sintered bronze or iron; alternatively, the bore of the guide ring can be lined with lowfriction material such as molybdenum disulphide filled nylon. Any tendency to leakage of air into the cylinder upon forward movement of the piston is prevented by the differential pressure across the rings forcing the free inner part of the flexible ring axially away from the guide ring, thereby causing contraction of the ring around the rod and compression of the part 10 between the tongue 8 and cylinder wall. The cylinder is mounted on a reservoir and separated from the air-space in the reservoir by a resilient diaphragm and foot-valve.

Filed: 1967-08-24
Abstract: 1,205,271. Transparent laminate. ENGLISH ELECTRIC CO. Ltd. 24 Aug., 1967 [27 April, 1967], No. 38975/67. Heading B5N. [Also in Divisions B2 and H5] A transparent laminate having an internal metallic coating to provide infra-red radiation reflecting properties, has the coating formed on at least part of a roughened surface of a substrate and a plastics layer, of similar refractive index to the substrate, in intimate contact with the surface defined by the coating or the coating and the substrate. This construction prevents the laminate from acting as a mirror whilst leaving the transparency of the laminate substantially undiminished. The plastics layer may be applied in layer form or in liquid form. In a first embodiment, the substrate, coating and plastics layer are respectively of transparent glass or plastics material, gold or aluminium or a metal oxide (e.g. stannous oxide), and polyvinyl butyrate. The two surfaces of the coating may have similar or different roughness patterns which may be regular or otherwise. The roughened surface of the substrate may be produced by grinding, chemical etching or sand blasting. The coating may be formed by vacuum deposition. It may provide for electrical resistance heating of the laminate, in which case two narrow strips of silver paste may be deposited along opposite edges of the coating for connection to an electric power source. The coating may not extend up to the edges of the laminate, and may not he continuous, in which case some of the peaks of the roughness pattern of the substrate will extend through the coating to contact the plastics layer, Fig. 3 (not shown). The outer surfaces of the laminate are smooth and may be plane and parallel or follow the same curve or follow different curves to obtain a lens. The substrate and the plastics layers may be of polyethylene terephthalate and polyvinyl butyrate respectively to produce a flexible laminate. The outer surface of the plastics layer may be covered with a further layer of glass or plastics material, either permanently or only during the lamination process.
