Patent GB-821251-A (GB)
Abstract: 821,251. Photographic materials. GEVAERT PHOTO-PRODUCTEN N.V. May 13, 1957 [June 7, 1956], No. 17649/56. Class 98(2) Direct positive photographic emulsions are fogged with a silane compound containing at least one Si-H group. The compound may be added in alcoholic solution or adsorbed on finely divided inert particles of silica, magnesium silicate or barium sulphate. In the examples, methyl di-chlor silane or tri-chlor silane are added to the emulsion prior to ripening in weakly alkaline conditions at a slightly elevated temperature. The emulsion is subsequently acidified and cooled and a desensitizer added so that an image-wise exposure to yellow light using the Henschel effect gives the direct positive; In one example the desensitizer is 2-thiol- 3-nitrophenyl-4-methyl-6-dimethyl 1 pyrimidine. A further desensitizer is specified. The use of known pre-fogging agents such as hydrazine, hydroxylamine, formaldehyde and stannous chloride, salts of gold palladium, platinum, iridium, ruthenium or strontium, sodium thiosulphate and thiosinamixie are referred to. Specification 796,873 is referred to.

Title: An automatic transmission for a vehicle
Inventor: YOKOYAMA SHOJI
IPC: F16H61/662
Filed: 1983-04-29
Abstract: An automatic transmission has a belt drive continuously-variable speed transmission mechanism and a hydraulic control circuit. The hydraulic control circuit includes a reduction ratio control valve 81 which has an axially slidable pool 812 and two pressure chambers 815, 816 formed in the valve body thereof one at each axial end of the spool. Conduits are provided for conducting working fluid at a pressure representative of the degree of throttle opening to the pressure chambers of the reduction ratio control valve, each of which has a solenoid valve 84 or 85 adapted to drain the pressure chambers when actuated. The solenoid valves may therefore control the flow of hydraulic fluid at a pressure lower than the line pressure and can consequently be less robust and expensive. <IMAGE>

Title: Controlling the wrapper rolls of a strip coiler
Inventor: TSUKII KATSU
IPC: B65H18/08
Filed: 1984-02-24
Abstract: A coiler for coiling a strip (2) onto a mandrel (4) includes peripherally arranged wrapper rolls (5a to 5d). Each wrapper roll is radially movable by a hydraulic cylinder (9) controlled by a servo valve (12) so as to cause each wrapper roll (5) to jump to avoid a step formed by a leading edge of the strip wound around the mandrel. For at least a part of the time the control system exerts an open loop control. In the first embodiment, the wrapper roll initially bears against the wound strip with a preset pressure set by unit (19). At the first step of the wound strip, switch (23) is opened and switch (24) is closed so that unit (18) causes the wrapper roll to move radially outwardly. After a preset time, switch (24) is opened and switch (25) closed so that unit (20) causes the wrapper roll to move radially inwardly and bear against the strip being wound. Finally, switch (25) is opened and switch (23) closed so that unit (19) again controls the pressure at which the wrapper roll bears on the strip being wound. In a second embodiment, the servo valve controlling the movement of the wrapper roll is influenced by a servo current so that the valve spool moves linearly. The position sensor for the wrapper roll and the feedback circuit are eliminated in this embodiment. <IMAGE>

Title: A method of detecting and removing visible defects in textile fabrics
Inventor: REIM INGEBORG
IPC: D05B23/00
Filed: 1984-02-29
Abstract: A method is for detection and removal of visible defects in textile fabrics which is moved as a defective material web in the longitudinal direction via a defect testing and detection area, characterised in that visible defects are detected as a deviation from the nominal value and the defective material web containing the defects is held over a needle bed, in which felting needles are used. Subsequently the defective areas with excess material and/or the defective areas with missing material, the repair material of which is supplied from a store so that it at least covers the defect and is supplied in the same direction of movement as the defective material, either above or below the latter, are stitched in such a way that the defective areas are penetrated on a needle bed together with the repair needle in the case of missing material by at least two felting needles of a stitching device controlled in a sectional manner, at a rate of 50-500 stitches per square centimetre. After the last stitch has been made further movement of the defective material web is triggered and occurs at a faster speed than that of the non-adapted repair material such that the defective material web is released by the tearing or cutting of the store.

Filed: 1985-01-18
Abstract: A spray container or aerosol 1 has a spray valve 2 and, internally, is provided with a butyl rubber sleeve 4 surrounding a textile mesh sleeve 7 and a core 5. When an outer chamber 6 is filled with a liquid to a level 17, that liquid is progressively transferred to an inner chamber (inside the sleeve 4) by capillary action through the sleeve 7 with expansion of the sleeve 4 (see Fig. 2) against the resilient opposition of the latter. Upon operation of the spray valve 2, the expanded sleeve 4 will contract and eject the liquid which it contains. The container 1 is refillable and no propellant gas is required. An inner sleeve 8 can be located between the core 5 and the textile sleeve 7, and the bottom of the core 5 and sleeve 8 are so constructed as to facilitate the ascent of the liquid. <IMAGE>
