Title: Fibre coating composition method of application and product thereof
IPC: C09D183/04
Filed: 1979-09-24
Abstract: Unique chemical formulation used in the manufacture of substantially wind-resistant, water-repellent fabrics. The formulation comprises a silicone polymer catalyzed with at in compound and optionally includes acetic acid and an aromatic solvent. A method for treating fabrics includes depositing the unique formulation on a taut fabric, uniformly distributing it across the width of the fabric and curing that product. Either before or after that treatment, the fabric is padded with or dipped in a bath of silicone or hydrofluorocarbon. Excess solution is removed. Last, the multicoated fibers of the fabric are compressively shrunk. A substantially wind and water-resistant fabric is produced that is not only porous and soft but also durable.

Title: A Method of Injecting Fuel in an Air-compression Internal Combustion Engine
IPC: F02B19/14
Filed: 1980-10-23
Abstract: The method comprises spraying at higher loads a fuel jet (17) through an ignition chamber (9) and a connecting passage (10) onto the wall (18) of a combustion chamber (4), where it spreads as a thin film (19). The air flow in the ignition chamber (9) during the compression stroke of the piston (2) and control of fuel injection is such as to cause individual fuel particles to be separated from the fuel jet (17) to form an ignitable mixture with the air and residual gas remaining in the ignition chamber (9). This ignitable mixture is ignited in the ignition chamber (9) so that a flame penetrates through the connecting passage (10) into the combustion chamber (4) to ignite the fuel evaporating from the combustion chamber wall (18). At idling and lower loads the injector provides an atomised spray (20) and an igniter provides for starting. <IMAGE>

Patent GB-2081958-A (GB)
Title: Tape transport apparatus; tape tensioning
IPC: G11B15/26
Filed: 1981-08-11
Abstract: Belts 7, 8 wrapped round respective tape reels 1, 2 are interconnected 17, so that the supply reel belt drives the take-up reel belt but at increased speed to tension the tape, by means of pulley(s) of tapering, stepped or otherwise variable diameter. The apparatus has tape take-up and supply reels 1, 2 and a capstan 4 for reversibly transporting tape 3 between the reels. Endless belts 7, 8 mounted on a plurality of rollers 9a to 9d are in contact with the peripheries of the tape on the reels 1, 2. The belts are tensioned by a common spring 12 which acts between levers 10, 11 carrying respective rollers 9d over which the belts 7, 8 pass. The rollers 9a are mounted on shafts which carry respective frusto- conical rollers 15, 16 round which a drive belt 17 runs. A freely rotatable shaft 18 lies normal to the plane of the belt 17 and serves to twist the centre region of the belt 17 out of the normal plane of the belt so that one run of the belt runs above the shaft 17 and one below. Thus, for one direction of rotation of the reels, 1, 2 the belt 17 runs on a larger diameter on one shaft and a smaller diameter on the other and vice versa when the direction of transport of the tape is reversed. In this way tape tension is maintained for both directions of transport. Slipping clutches 19 may be incorporated. Recording head 6 presses against slightly resilient capstan 4. <IMAGE>

Title: Method of making electron tube envelope assemblies
Inventor: GAIR SALEM ABRAHAM
IPC: C04B37/02
Filed: 1981-09-14
Abstract: A method of making an electron tube assembly comprising a ceramic tube 2 disposed between and sealed at its ends to two annular metal members 5, 6. Such an envelope assembly may be used, for example, in the manufacture of an image-intensifier tube. A problem in making such an envelope assembly is to consistently produce assemblies economically with the longitudinal spacing between the annular metal members held to close tolerances. Ceramic tubes 2, 3, 4 and annular metal members 5, 6, 7, 8 are assembled in a jig 1, a glass ring (9, 10, 11, 12, 13, 14) is interposed between each end of the ceramic tubes 2, 3, 4 and the opposed annular metal members 5, 6, 7, 8. The jig 1 has supporting surfaces constituted by the horizontal surfaces of stepped horizontal portions 16 to 20 of an integrally formed base member 15, and the upper horizontal surface 32 of a cylinder 26 which is coaxial with and supported by the base member 15. The jig 1 and assembled components are heated so as to soften the glass rings, and a weighting member 27 pressing down on the annular metal member 5 causes the glass rings to deform so as to form seals between the ceramic tubes 2, 3, 4 and the opposed annular metal members 5, 6, 7, 8, providing de- sired longitudinal spacings between the annular metal members 5, 6, 7, 8. After sealing there is a continuous thickness (not more than 0.5 mm) of glass between each annular metal member and the opposed ceramic tube surface. <IMAGE>

Title: Treatment of organic waste
Inventor: GIBSON GEORGE MURRAY
IPC: C12M1/107
Filed: 1983-05-19
Abstract: Waste is placed in a closed digester tank (21) located beneath a glasshouse (10) and all the methane generated by digestion is collected in a collection chamber (25) and delivered to a boiler (35) where it is burnt to heat water which is circulated through pipes (39) in the digestion tank (21) to heat the waste to a temperature at which thermophyllic organisms are active, thus improving the breakdown of the waste and generating heat which is transmitted to the glasshouse. The digested waste is transferred to hydroponic culture troughs in the glasshouse. Thus the organic waste provides both heat to warm the glasshouse and nutrients for the plants growing therein. <IMAGE>

Title: A procedure for the hardening of materials
Inventor: DEARNALEY DR GEOFFREY
IPC: C22F3/00
Filed: 1983-05-24
Abstract: A method of hardening metals or ceramics which have fcc, bcc or hcp structures in which two species of differing atomic radii are introduced into the material to be hardened. One species is of a size such that it can diffuse through the lattice normally. The other is of a size such that it can diffuse readily only along dislocations. Ion bombardment is the preferred method of introducing the species with different atomic radii. The material to be hardened is subjected to heat and plastic deformation so as to cause a large number of dislocations with jogs. The species meet at the jogs where they interact and are trapped and set up strain fields which prevent further deformation of the material.
