Abstract: 1,154,566. Moulding drafting aprons. GEORGE ANGUS & CO. Ltd. 22 Sept., 1966 [30 Sept., 1965], No. 41514/65. Heading B5A. [Also in Division D1] A method of manufacturing drafting aprons comprises mounting an unwrinkled sleeve of an open mesh textile material on a smooth cylindrical mandrel, applying a layer of unvulcanized rubber over the sleeve, and, after applying reinforcement, e.g. a helically wound layer of cord, and then a further unvulcanized rubber layer, vulcanizing the rubber whilst supported by the mandrel, stripping the vulcanized rubber sleeve so formed and the textile sleeve together from the mandrel, and then stripping the textile sleeve from the rubber sleeve to leave on the internal surface thereof a grooved pattern of wholly curved lines. The textile sleeve may be a seamless loosely-knitted fabric of cotton, rayon nylon or poly-(ethylene terephthalate). The textile sleeve may be moistened with a release agent to assist removal from the vulcanized sleeve. The rubber sleeve may be externally ground before removal of the knitted sleeve and the composite article may be chemically treated to reduce its surface friction and sliced to the required width.

Abstract: 894,099. Angular bending; seaming. ALUMINIUM DISTRIBUTORS Ltd. Dec. 13, 1960 [Dec. 22, 1959], No. 42892/60. Class 83 (4). A tool for seaming sheet metal comprises a frame adapted to surmount the prepared edges of sheets, which edges are longer than said frame, working members adapted to engage parts of the edges and folding means operable to cause one of said working members to engage and fold at least one of said prepared edges. The frame 1 comprises side members 2 attached to a forward base-plate 3 and a rearward base-plate 4 and which have semicircular openings 5. On the inner surface of each member around the opening 5 is an annular groove 6. The forward base-plate 3 terminates in an upturned lip 11 and is faced underneath with a soft material 12 to avoid scratching the sheets. The rear base-plate 4 is similarly covered and carries a clamping member 14 which co-operates with the lip 11 to clamp the sheets. The member 14 is fastened to a frame 19 which has lugs 20 which connect the frame to an operating means comprising an eccentrically-mounted shaft 21, bearing blocks 25 and a slidable plate 15 arranged so that rotation of the handle 22 in a clockwise direction as seen in Fig. 2, closes the member 14 on to the lip 11. The folding means comprises a channel-section 29 which has a quadrant plate 28 attached to each end bearing a semi-circular bar which runs in the groove 6. The channel is rotated by a handle 32. The prepared sheets comprise one which has an upstanding edge and the other which has an upstanding edge and a further portion extending parallel to the sheet. To prepare the sheets for seaming the further portion is bent down to grip the upstanding edge of the other sheet. The seaming tool is applied, the clamping means operated by the handle 22 and the folding means operated by the handle 32 to bend the top part of the seam at right-angles, or preferably a little more to the remaining part of the upstanding joint. To complete the joint the upper part of the seam is folded down against the lower part by a tool having hinged jaws and operating handles. Specification 866,156 is referred to.

Title: Improvements in or relating to control apparatus for use in aircraft
IPC: G05D1/06
Filed: 1967-09-25
Abstract: 1,148,354. Automatic control of aircraft. HONEYWELL Inc. Sept.25, 1967 [Sept. 30, 1966], No. 43515/67. Heading G3R. The angle of attack of an aircraft is compared with a selected reference value which varies with acceleration of the aircraft normal to its roll and pitch axes, any difference being eliminated by causing a signal dependent on the difference to control the power output of means propelling the aircraft. In Fig. 1, devices 18, 25 and 20 produce electrical signals corresponding to the angle of attack, reference value, and normal acceleration which are combined to control engine throttles 14. The acceleration signal is amplified at 23 and the arrangement is such that when, for example, upelevator is applied automatically or manually during a banked turn, the effect on the control system of the resulting increase in the angle of attack signal is cancelled by the effect of the normal acceleration signal so that there is no undesired adjustment of the engine throttles. Follow-up signals dependent on throttle movement are fed back through a high-pass filter 34 and, if desired, a signal dependent on airspeed measured at 17 may be fed back through a high-pass filter 29.

Abstract: 1282778 Direct-positive silver halide photographic process EASTMAN KODAK CO 5 Sept 1969 [9 Sept 1968] 44081/69 Heading G2C A method of making a positive photographic record comprises imagewise exposing a sensitive photographic material comprising a layer of a direct-positive silver halide emulsion which contains an electron-accepting compound and a BSI compound (as defined in U. K. Patent Specification 1186718), and of which the silver halide comprises at least 50 mole per cent of silver chloride and of which the grains have internal centres which promote the deposition of photo-lytic silver and surface-fogged outer shells or regions and surfacedeveloping the exposed layer using a polyhydroxybenzene developing agent. The developer may be in the material, in a solution or in a layer on a separate support which is brought into contact with the material. Surface development may be effected with a 'lith' developer (i.e. one capable of giving infectious development) which may contain a carbonyl bisulphite-amine condensation product with at least 0À075 mole of excess free amine per litre and a dihydroxybenzene developing agent. The internal centres which promote the deposition of photo-lytic silver may be produced by chemical sensitization e.g. with potassium chloroiridite, or by fogging by exposure to low or high intensity light. The grains may be surface fogged by chemically sensitizing to fog or by exposure to high intensity light. In the examples the grains are surface fogged by heating with thiourea dioxide and potassium chloroaurate. The electron acceptor may be 1, 1'-diethyl-2, 2'- cyanine chloride treated with N-bromosuccinimide or 1, 3-diethyl-1'-methyl-2'-phenylimidazo- [4, 5-b] quinoxalino-3'-indolocarbocyanine iodide.
