Abstract: 1,097,528. Photo-electric tachometers. SMITHS INDUSTRIES Ltd. July 15, 1966 [July 20, 1965], No. 30790/65. Heading G1A. Apparatus for measuring the rate of rotation of a rotary member by measuring the frequency of pulses produced by a photo-cell receiving light from the surface of the member comprises two triangular prisms 6, 7, the bases of which cooperate respectively with a lamp 12 and phototransistor 14 so that light from lamp 12 leaving surface 10 is reflected from the rotary member through the surface 11 to the photo-transistor.

Title: Improvements in or relating to machines for operating progressively along marginal portions of shoe parts
IPC: A43D27/00
Filed: 1958-09-27
Abstract: <PICT:0926694/III/1> <PICT:0926694/III/2> A machine having a tool for operating progressively along marginal portions of shoe parts, means for feeding the part with respect to the tool and for grinding it relatively thereto, is provided with a marking device for automatically applying to the shoe part, as it is fed into the machine, a mark at the position where the operation of the machine is to end.  The invention is described as applied to a machine similar to that shown in Specification 467,562.  The machine has two feed-rolls 2 and 4, the roll 4 being carried on an arm 14, which may be raised on depressing a treadle (not shown) to cause the rolls to grip and forward a shoe insole I.  Mounted on the arm 14 are a work-table 10 and edge-gauging means 12.  The roll 2 is mounted on a shaft journalled in an arm 16, which carries a bracket 18 on which is mounted an end gauge 20.  The position of this may be adjusted by rotating the screw 24 by means of the knob 26.  The end-gauge 20 is so arranged that raising the feed-roll 4 lifts the insole I above it, so that the insole may be moved as required, for application of adhesive thereto by a nozzle 30, carried on an adjustable bracket 32. An arm 36 extends from the bracket 32, and carries a sleeve 38 in which slides a tube 42 carrying a marking device 40, e.g. a ball point pen.  The device 40 is urged downwardly by a spring 46 to contact the insole as it is moved into position, and is then retracted by means of a bowden cable 44 connected to the treadle when the latter is depressed to initiate operation of the machine.

Abstract: 1,139,014. Luminescent screens. EASTMAN KODAK CO. 6 July, 1967 [8 July, 1966], No. 31099/67. Heading C4S. [Also in Division G2] Fluorescent layers for use in photographic materials are obtained by dissolving a waterinsoluble organic fluorescent compound and a water-insoluble carrier for said fluorescent compound which forms a solid solution therewith, e.g. polymers of styrene and copolymers thereof with alkyl acrylates or poly-vinyl benzoate, in a solvent which is water-soluble, e.g. ethylacetate, or contains a water-soluble component, dispersing the solution into a colloidal state in an aqueous solution of an hydrophilic film-forming binder, e.g. gelatine, casein, cellulose, or vinyl polymers, washing the dispersion with water to remove the water-soluble solvent, coating the washed dispersion on a support and drying. The fluorescent layer may be a silver halide emulsion layer, an overcoat or undercoat layer for such an emulsion layer or a backing layer of a photographic silver halide material. The dispersion is washed by coagulating or gelling the dispersion in the aqueous hydrophilic colloid and then washing. The fluorescent layer may contain pigments, hardeners or colour couplers and may have a silver halide emulsion and/or a coating containing an electrically conductive compound between itself and the support, e.g. cuprous iodide in a poly-(methyl acrylate, vinylidene chloride, itaconic acid) terpolymer. Specified fluorescent compounds are 3-phenyl-7- ureido coumarin, diphenyl oxazole and 1,4-bis- (2-(5-phenyl-oxazolyl))-benzene. A protective layer of vinylite and a cellulosic nitrate subbing layer may be applied over the electrically conductive layer to bond a silver halide emulsion thereon.

Title: Improvements in fuel flow regulators
Inventor: LEESON PLATO JOHN
IPC: G05D7/01
Filed: 1962-08-14
Abstract: 1,008,190. Gas turbine plant. WOODWARD GOVERNOR CO. Aug. 14, 1962, No. 31206/62. Heading F1G. [Also in Division G3] A fuel control system for a gas turbine engine comprises a valve 10 movable to control the flow of fuel through a line 11 by a fluid pressure acting on a piston 25. A first control valve 34 is movable in response to a speed governor 33 to control the fluid pressure acting on the piston 25 while a second control valve 35 is movable in response to actual fuel flow through the valve 10 compared with a computed fuel flow in respect of compressor outlet pressure, or any parameter such as altitude or temperature so that the control valve 35 acts to override the control by the valve 34 when the actual fuel flow is outside a computed range. Compressor outlet pressure acts through a cam 72 on a lever 76 while the actual fuel flow indicated by the position of piston 25 acts through a cam 78. When the actual fuel flow is within the computed range, a land 83 is positioned to connect a low pressure source Po to conduit 40 and a high pressure source Pc to a conduit 39. Valve 34 moves in response to speed changes to connect a passage 60 to either conduit 39 or 40. In operation, assuming that the actual fuel flow is within the computed limits, if the engine speed drops due to increased load the valve 34 moves downwards and connects passage 60 to conduit 39 and high pressure fluid acts on a spring loaded piston 61 which moves downwards to increase the pressure in passage 63 causing the valve 10 to open further. Either side of the piston 61 are connected to the opposite sides of a piston 67 to apply a differential pressure to move valve 34 upwards to its position closing the passage 60. A bleed passage 68 in piston 61 allows the piston to recentre and equalise the pressures. Thus an isochronous operation of the governor is provided. If during acceleration the valve 34 is moved to demand a larger fuel flow the passage 60 communicates with the high pressure source through conduit 39 as above. If the actual fuel flow then exceeds the computed maximum or the computed maximum is reduced, valve 35 moves downwards and land 83 first closes conduit 39 from the high pressure source 37 to prevent fluid pressure passing to passage 60 to open valve 10 further and any further movement of valve 35 connects conduit 39 to the low pressure source 38 to allow exhaust from passage 60 to close the valve 10 to the lower computed maximum fuel flow, the valve 35 thus overrides the increased fuel flow demanded by valve 34. A similar operation occurs with the valves 34, 35 moving upwards with deceleration or an increased computed minimum fuel flow.
