Title: Improvements in and relating to photographically printing on materials
IPC: G03C1/76
Filed: 1947-01-21
Abstract: 633,634. Photographic contact printing. STEWART, L. R. Jan. 21, 1947, No. 1841. [Class 98 (ii)] Materials such as fabric, leather, paper, plastics and furs are impregnated with an aqueous solution of a leuco ester combination or compound known by the Trade name " Algosol," exposed to light rays through photographic negatives to render portions of the " Algosol " insoluble in water, washed to remove the still soluble portions and, finally framed and dried. " Algosols " are obtainable from the American Cyanamid Corporation, New York, or the General Dyestuff Corporation, New York, they are soluble in water but are rendered insoluble by the action of light and are available in a wide range of colours. In the case of certain of them, such as Algosols 04B and IRRD, formic acid may be added to the solution to accelerate the action of light on the dye and in some instances it has been found that the use of urea or hygroscopic agents such as glycerine have a favourable accelerating influence. As described with reference to drawings a fabric 12 is fed under a roller 17 within a tray 14 containing dye solution 15 to squeeze rollers 18, 19 and passes over rollers 23 with pins 23<SP>1</SP> to engage the selvage as it moves along, and then around driven transparent cylinders 24, 27 fitted with internal light units 25, 28, both of which cylinders may carry negatives when both sides of the fabric are to be printed. Washing is effected by water from sprays 62, 64 and in baths 39, 43, 46 and 49, the first of which may be provided with soapy water from receptacle 61<SP>1</SP>, and from the washing mechanism the fabric passes round a drying and framing drum 50 which has pins 50<SP>1</SP> to pierce and grip the selvage and stretch the fabric to its original size and it is, finally, wound up at 54. If more than one colour is desired the fabric may be passed through another identical set of equipment which is provided with another sensitizer. Reference has been directed by the Comptroller to Specifications 417,588 and 523,296.

Title: An improved valve for automatically controlling the water level in troughs and the like
IPC: G05D9/02
Filed: 1956-01-20
Abstract: 792,354. Fluid-pressure servomotor-control systems. WYLIE, J. Jan. 20, 1956, No. 2038/56. Class 135. The valve is secured in a vertical position to the edge of a water trough and water from the supply flows into a pipe 4 from which it exhausts into the trough via a filter 8, an orifice 9, an inlet chamber 5, a passage 23a, an outlet chamber 27 and an outlet 24a. As the trough fills, the water first covers a hole 25b in the bottom of a depending pipe 25a and then rises up the inside and outside of the latter causing increasing compression of the air trapped in the pipe 25a; as the water approaches the desired level 33 the air pressure is sufficient to lift a secondary diaphragm 26 so that a rubber or like valve closure 31 bears against a seat 23b at the extremity of the passage 23a and resists flow into the outlet chamber 27, whereupon the resulting pressure rise in the inlet chamber 5 elevates a spring-loaded main diaphragm 10 and partially seats a rubber or like main valve closure 21 in the orifice 9. When the water reaches the level 33 the secondary diaphragm 26 causes the closure 31 to completely shut-off the passage 23a so that the pressure in the inlet chamber 5 acts on the diaphragm 10 and forces the main closure 21 completely into the orifice 9 to prevent any further flow through the apparatus. Removable plugs 32 in the pipe 25a are provided to compensate for lower supply pressures whilst a pipe of increased length is used if the supply pressure is very high.

Abstract: 973, 699. Programmed control of machine tools. SPERRY GYROSCOPE CO. OF CANADA Ltd. Jan. 20, 1961 [Feb. 4, 1960], No. 2363/61. Heading G3N. A device having two channels for controlling two measures according to a programme is checked by transposing parts of the two channels and comparing the responses to the same command data. As shown, a digital position control system for elements 11, 12 of a table of a drill press, responds to commands from a punched tape 10 scanned by X and Y channel tape-readers 14, 28. Each channel has a digital-to-analogue convertor 16, 30 feeding a comparator 18, 32 determining the error between a signal representative of the actual position of the controlled element 11, 12 and a signal, representative of the desired position, from the converters. The element is driven by a servomotor 24, 36, responsive through a servo-amplifier 22, 34 to the output of the comparator, in a direction tending to reduce the error to zero. When both the amplified error signals have fallen to zero relays 80, 82 are de-energized to connect a battery 90 to a tapemechanism 94. The tape 10 is then advanced to apply transposed X and Y data to the readers 14, 28 and "check" data to a reader 64. The output from tape-reader 64 energizes a relay 44 to transpose the position of comparators 18, 32, energizes a relay 68 to disconnect the servo-amplifiers 22, 34 from the servomotors 24, 36 and energize a relay 69. If the system is operating correctly the result of transposing the data and the comparators will still produce a null and relays 80, 82 will remain de-energized and since relay 69 is energized the drilling head of the machine 96 will carry out an operation. At the end of the operation a signal is fed the mechanism 94 to advance the tape for the next block of X and Y data. The operation of the machine can be initiated by an operative acting in response to the indicator 98, the data reader 98 is not then required.

Abstract: 891,002. Generating combustion products under pressure. BOLL8-ROYCE Ltd. Jan. 15, 1960 [Jan. 22, 1959], No. 2376/59. Class 51 (1). [Also in Group XXVI] Reheat combustion equipment for a gasturbine engine comprises at least two reheat fuel injectors each of which discharges at a location upstream of the respective spaces between each of at least two tubular shields mounted one within the other, the fuel being substantially wholly vaporized within that space by virtue of its contact with the hot gases. In Fig. 2, where the invention is shown applied to the jet pipe 13 of a gas and turbine jet propulsion engine, reheat fuel is supplied from three ring manifolds 16, 17, 18 which are successively supplied with fuel from a tank 19 as a piston valve 26 is moved to the left. A nozzle 29 is disposed in a hollow baffle 28 positioned centrally of the jet pipe by a spider 15, and is supplied with fuel independently of the valve 26 so that it may act as pilot for the ignition of fuel supplied from the manifolds. Two concentric gutters 31, 32 interconnected by three radially-extending gutters, are mounted at the downstream end of the baffle 28 to stabilize the combustion of the reheat fuel. The gutters 31, 32 are respectively mounted within tubular shields 34, 35 which radially confine the fuel injected by the manifolds to ensure that substantially the whole of the fuel is burnt in the burning zone. The shield 35 is held in spaced relationship with the jet pipe by corrugated strips 37, 38 so that the jet gases pass through the annular space 36 to cool the jet pipe 13. That portion of the shield 35 extending down-stream of the gutter 32 may be corrugated and/or perforated to assist in suppressing " reheat howl." The volume of the space within the shield 34, and the volume between the shields 34 and 35 are selected to maintain the fuel/air ratio at or near the stoichiometric value. The upstream end of the shield is provided with a corrugated member 39 which directs part of the boundary layer flow in the jet pipe to the inside of the shield 35 and part of it to the annular clearance 36 for cooling the jet pipe.
