Abstract: 518,072. Treating textiles with liquids ; cellulose derivative solutions. EVANS, J. G., SMITH, R. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 15, 1938, No. 21110. [Classes 2 (ii) and 15 (ii)] Textile materials are sized or finished with water-soluble cellulose derivatives, e.g. watersoluble cellulose ethers and simultaneously or subsequently with a water-soluble condensation product of formaldehyde and urea or thiourea, e.g. monomethylol urea or dimethylol urea, or a derivative thereof such as the dimethyl ether of dimethylol urea. The materials are then subjected to a short heat treatment, e.g. at a temperature between 110‹ and 180‹C. The finishes produced by the application of the water-cellulose derivatives are rendered more resistant to water or other aqueous treatment liquids, by treatment with the condensation product. The water-soluble cellulose derivative may be applied by immersion of the textile, or by padding methods. After this treatment the textile while still wet or after drying may be treated with an aqueous solution of the watersoluble formaldehyde-urea compound. It is then dried and subjected to a short heat treatment. Alternatively the textile may be treated. with a solution containing both the cellulose derivative and the water-soluble condensation product. The cellulose derivative may be a water-soluble methyl, ethyl, or methyl ethyl cellulose ether. Textiles of cotton, cellulose ester or ether fibres, animal fibres, or artificial fibres of protein origin may be treated. A spun viscose fabric is padded with an aqueous solution of methyl cellulose, squeezed, and dried, then padded with an aqueous solution of dimethylol urea. It is again dried and then heated to 150‹C. The fabric has a full linen-like handle which is not removed by usual laundering operations. Cotton casement fabric is treated with an aqueous solution of ethyl cellulose and then with an aqueous solution of dimethylol urea. Cotton limbrick fabric is treated with an aqueous solution containing methyl ethyl cellulose and dimethylol urea, and a small amount of ammonium dihydrogen phosphate. The fabric is squeezed, dried and heated to 150 degrees. The fabric has a linen-like handle resistant to laundering. Specifications 452,506 and 469,391 are referred to.

Abstract: 719,469. Gas turbine plant; centrifugal pumps; centrifugal governors. ROLLS-ROYCE, Ltd. Sept. 11, 1952 [Sept. 11, 1951], No. 21432/51. Classes 57, 110(1) and 110(3) A fuel system for a gas turbine plant comprises a centrifugal fuel pump having flow-restricting means connected with its delivery and flow-metering means in its inlet, the flow-metering means being controlled by a speed governor sensitive to a rotational speed to be governed, the arrangement being such that in operation of the pump the radial depth of fuel in the pump impeller is less than the impeller radius. The fuel tank 14, Fig. 1. is pressurized by connecting it through a pipe 44 to an intermediate stage of the compressor 10 of the gas turbine plant or through a pipe 45 to the delivery of the compressor. Fuel passes to the eye of the fuel pump impeller 20, Fig. 5, by way of a duct 15 and a valve 39. A centrifugal governor 29 driven, together with the impeller 20, from the rotor 10 a of the compressor 10, tends to close the valve 39 against the combined effect of a spring 42 and the pressure exerted on a flexible diaphragm 50. The diaphragm 50 is subjected on one side to the pressure within a chamber 51. This pressure is a fixed proportion of the compressor delivery pressure and may be obtained by connecting the chamber 51 by way of a duct 52 to the pipe 44 or 45. The cavity 21 is vented to atmosphere through pipes 54, 43. In a modification, Figs. 2 and 4, the diaphragm 50 is omitted, and the stem 37 of the valve 39 is made hollow to provide a passage connecting the cavity 21 to the vent pipe 43. The centrifugal governor 29 comprises bob weights 30 secured to the ends of a spring steel strip 34 overlying the end of the stem 37 and to the ends of spring steel strips 31 carried by lugs 32 projecting from a boss 33 secured to the impeller 20. The bob weights 30 have inwardly extending arms 35 ending in knife edges 36 which bear upon the centre of the strip 34 to load the valve 39. The centrifugal governor 29 may be replaced by a hydraulic governor comprising a fixed capacity pump driven at the speed to be governed and delivering liquid through an orifice which may be adjustable, the pressure drop across the orifice being applied to a piston which moves the valve 39 against a resilient load which may be adjustable. Specification 709,002 is referred to.

The combustion equipment comprises an annular flame tube 24, 28 disposed within a casing 17, a series of channel-section members 20 being disposed circumferentially so as to form the outlet from the annular flame tube. The channel members 20 have holes 21 in their side walls through which dilution air flows to mix with the combustion gases. The channel members have " keel " portions 20<SP>1</SP> by which they are supported from the inner tubular wall 22 and which in turn support three concentric annular vanes 23. The inner flame tube wall 24 is curved and projects into the air inlet and divides the air stream into two parts, viz. combustion air and dilution air. The combustion air flows through the annular passage 25 between the flame tube wall 24 and the outer casing 17 and a portion thereof enters into the combustion space 16 through a series of apertures 33 provided in the portion of the flame tube wall indicated at 3. Fuel is supplied through injectors 34 and the resulting combustion gases discharge through the channel members 20 to the inlet nozzle guide vanes 14 of the turbine 15. The dilution air stream is guided by the vanes 23 and enters the channel members 20 through the apertures 21, there mixing with the combustion gases and cooling them. The remaining portion of air from the passage 25 passes around the flame tube and flows along the other wall 28 thereof so as to cool it, the air finally discharging into the combustion gases within the channel members 20. The object of the invention is to provide a vertical lift engine of reduced axial length which may be mounted vertically within an aircraft wing.

Abstract: 509,371. Refrigerators. ELECTROLUX, Ltd. July 21, 1938, No. 21700. Convention date, July 21, 1937. [Class 29] The humidity of the air in a refrigerator having a two - temperature evaporator or cooling unit is varied by changing the path of now of the air over the two parts of the cooling surfaces so that more or less moisture is deposited on the cooling unit. The evaporator may comprise a low temperature part 24 'consisting of coils embedded in the walls of an ice-making compartment and a warmer part located above the first and consisting of coils 19 with aircooling fins 23. In the embodiment shown these are parts of a single evaporator of an absorption refrigerating apparatus of the inert gas type, and liquefied refrigerant enters the upper coil and inert gas the lower coil and are in counterflow. The temperature may be determined by a thermal element 59, Fig. 3, embedded in the wall of the ice-making unit, the temperature control including a manual setting member 54, Fig. 2, and cords 57 acting on energy control mechanism. The evaporator parts are screened by a casing comprising horizontal portions 30 and vertical portions 31 having openings 37, 38 and 39, 40 respectively, controllable by slides 41, 42 respectively. The slides are acted on by springs 52, 53 and are movable simultaneously by cords 47 attached to pulleys on a shaft 44 with a setting knob 43. With the slides in the position shown air flows by natural circulation through openings 38 and descends past the wall of the ice-making element, where moisture is deposited as frost. When the apertures 37, 39 are opened the air does not flow past this wall and is less strongly cooled and dried. A drip pan 35 is arranged below the ice-making unit. The slides may be controllable by a humidostat. The Specification, as open to inspection under Sect. 91, includes forced air circulation. This subject-matter does not appear in the Specification as accepted.

Abstract: 685,693. Optical and photographic apparatus. VINTEN, C. July 24, 1950 [Aug. 22, 1949], No. 21744/49. Classes 97 (i) and 98 (i). [Also in Group VIII] An illuminating system comprises a plurality of light beams of different pre-arranged constant colours, screening means incorporating apertures of prearranged sizes for independently determining the amounts of light of the various coloured beams to be utilized, and means for mixing the beams. The kinematograph film printer shown in Fig. 3 has a light source with lamp 1, reflector 2 and condenser 3. The negative film is fed, by claw feed mechanism with registering pins indicated generally at 25, from a spool 18 to a spool 24 over rollers 19, 20, 22, 23. A second film may be fed simultaneously over rollers 26, 27 when required. The printing objective is indicated at 6. An opaque band 16, Fig. 2, is fed from a spool 30 to a spool 31 through a separate gate 29 between the light source and film gate. The band is provided with sets of apertures, each aperture being positioned to register with one of a set of filters 8, 9, 10 which control the colours of parts of the light beam. The sizes of the apertures control the relative amounts of the coloured beams, and an unaltered beam at 11, and hence the colour and intensity of the resulting mixed beam. Sets of apertures are provided in the band for different parts of the negative film and the band is fed automatically as each such part is reached. For this purpose a notch on the negative film actuates contacts, near the roller 20, which control a solenoid which releases a pawl to allow the spool 31 to be rotated the required amount by a continuously-rotating member acting through a slipping clutch. To obtain adequate time of operation of the contacts the roller 20 is rotated intermittently by an internally toothed gear engaged intermittently by a gear, held against rotation, but mounted on a pin carried eccentrically on a driven shaft. The Specification also describes a hand-operated punching machine for forming the apertures in the band 16 (see Group VIII).
