Title: Improvements in nozzles for vacuum cleaners
IPC: A47L9/02
Filed: 1957-05-30
Abstract: 865,715. Suction cleaned nozzles. ELECTROLUX Ltd. May 30, 1957 [May 30, 1956; June 7, 1956; June 11, 1956], No. 17173/57. Class 8(1). A vacuum cleaner nozzle is provided with means to turn a frame 19 having unlike operative surfaces 21, 22 progressively around an axis, and comprises a pedal 41, pivotally supported on a pin 42, engaging two horizontal pins 47 on the actuating member 48. Depression of the pedal 41, against the action of a spring 49, causes the claw-like end portion 52 of the member 48 to engage a notch 53 provided in the curved surface 23 of the frame. The frame is supported in the nozzle by shaped springs 36, and continual pressure on the pedal, assisted by the springs 36, turns the frame until the opposite surface is in the operative position. Notches 53 are provided on both sides of the frame so that another movement, as described above, returns the first surface to the operative position. A suction inlet 29 formed in the frame may have brushes 20 connected to the ends but supported to allow movement between the longitudinal frame walls 27, 28, at its mid length. An additional suction inlet 57 may be provided on the opposite side of the nozzle to the inlet 29, the nozzle being adapted to swivel to present this nozzle to the surface to be cleaned. Further embodiments describe the frame being supported by the turning members when the nozzle is formed by two hinged together parts held together under the action of a spring.

Title: Improvements in desiccation methods and apparatus
IPC: F26B5/06
Filed: 1944-09-08
Abstract: Solid and liquid foods, chemicals and plasma are desiccated without deterioration by exposing the substance to reduced pressure at a temperature below 50 DEG C., condensing and freezing the vapours, which are evolved, upon a surface maintained at a temperature below 0 DEG C., and repeatedly removing the solidified condensate from the surface while the process is in operation. The pressure is preferably maintained between 0.1 and 10mm., and the temperature of the condensing surface between -40 DEG  and -70 DEG C. The substance to be desiccated is introduced through a duct 12 into vessel 10 which is connected to a vacuum pump at 20 through port 18, condenser 26, receiver 62 and auxiliary condenser 92. The substance is agitated during desiccation and may be heated to prevent excessive lowering of its temperature which may occur owing to rapid vaporisation.  The vapours evolved are condensed and solidified on the cylindrical inner surface of condenser 26 from <PICT:0586693/III/1> <PICT:0586693/III/2> which the solid is continuously removed by a rotary scraper 36, extending longitudinally through the condenser, and deposited into the refrigerated receiver 62 kept at a temperature less than 10 DEG C. above the temperature of condenser 26.  The purpose of the auxiliary condenser 92, which is equipped with a rotary scraper 104, is to ensure that no vapour, sublimed from receiver 62, reaches the vacuum pump.  A grinder may be placed in the inlet duct 12 before the valve 13 if it is desired to reduce a solid to small particles before desiccation.  The substance may be heated by placing it between condenser plates connected to a high frequency electric current, or by the use of an infra red lamp.

Title: Improvements in or relating to thermionic amplifier circuit-arrangements with parallel feeding
IPC: H03F3/02
Filed: 1931-06-15
Abstract: 369,480. Valve circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. June 15, 1931, No. 17374. Convention date, June 21, 1930. Drawings to Specification. [Classes 39 (i) and 40 (v).] In an amplifier circuit employing parallel feed, the anode current is fed over a saturated diode having an indirectly-heated cathode. The invention utilizes the fact that a saturated diode has practically infinite resistance to alternating current and low resistance to direct current. The appreciable capacity between the diode filament and earth and between the amplifier valve filament and earth results in an effective capacity shunt across the diode which is eliminated by using an equipotential cathode and reducing the filament-earth capacity by winding the heater round the anode which is in the form of a spiral, and employing a very thin cathode.

Title: Improvements in or relating to gas turbine engines
Inventor: BELL FRANCIS ROBERT
IPC: F02C7/18
Filed: 1955-06-16
Abstract: 775,057. Gas turbine plant. BLACKBURN & GENERAL AIRCRAFT, Ltd. June 16, 1955 No. 17459/55. Class 110(3). [Also in Group XII] A gas turbine engine comprising an annular combustion chamber into which fuel is projected radially has air taken from the compressor delivery which is passed through sealing labyrinths at the front and rear of the shaft to enter the shaft and then through the turbine disc to issue rearwardly thereof. A compressor 2 discharges air through a radial diffuser 3 into a combustion chamber 5 having primary air entries 6 and a secondary air entry 7. Some of the compressed air passes through apertures 13 in the compressor back plate 4 into the space between the labyrinth shield 14 and the labyrinth 15. A part of this air passes between the edge of the shield 14 and the shaft 16 to issue radially around the fuel delivery 12. The remainder of this air passes through the labyrinth 15 and enters the shaft 16 through bores 17, 18. This air is thereby prevented from entering the diffuser 3 between the compressor 2 and backplate 4 which would impair the efficiency of the diffuser. Another part of the compressed air passes through the hollow stator blades 8 into the hollow annulus 9. Some of this air passes through bores 20, 23 and then traverses the face of the rear labyrinth 22 to enter the shaft 16 through bores 24. This air cools the centre of the turbine disc and prevents leakage of air over the front face of the disc which would interfere with the flow of combustion gases into the turbine blading. Another part of this air passes through chamber 10 and is discharged into the combustion chamber through orifices 11. A further part issues radially around the fuel delivery nozzles 12. The compressed air leaves the chamber 19 in the shaft 16 through axial bores 26 to enter an annulus 28 from which it is led by passages 29 in the bolts 27 to bores 30 from which it may flow over the rear face of the disc 25. If the turbine is of the two-stage type as shown the air from the bores 30 may traverse the face of the labyrinth 31 and pass through further bores 32 and passages 33 to issue through bores 34 over the rear face of the turbine disc 35. Specification 686,908 is referred to.

Abstract: 1501997 Decane dicarboxylic acid purification CHEMISCHE WERKE HœLS AG 28 April 1975 [29 April 1974] 17484/75 Heading C2C Decane dicarboxylic acid (1,10) is purified by distillation at 0À5 to 2 torr and at a bottoms temperature of 215‹ to 225‹ C., after the crude has been treated to decrease the content of organically combined nitrogen to 0À05% by weight or less, the content of free nitric acid to 0À02% by weight or less, and the water content to 0À1% by weight or less. The acid is prepared by the oxidation of cyclodecanol and/ or cyclododecanone with nitric acid with or without an oxidation catalyst. The combined nitrogen may be decreased by treatment with a strong oxidizing agent or thermal treatment. Thermal treatment at 150 to 200‹ C. may be used to decrease the nitric acid content and this also decreases the water content. A water washing may be used to reduce the nitric acid content but further dehydration is then necessary. A conventional falling film evaporating apparatus used continuously or batchwise may be used.

Title: Improvements in textile materials
IPC: D06M13/188
Filed: 1931-06-18
Abstract: Filaments, threads, or yarns of organic cellulose derivatives are shrunk at intervals along their length.  This may be effected by local application of a shrinking agent such as acetic, formic, or lactic acid, acetone, diacetone alcohol, ether-esters of olefine glycols or of polyolefine glycols, dioxane, ethers of propylene glycol or diethylene glycol, phenols, acetins, ethyl lactate, diethyl tartrate, methylene chloride, ethylene chloride, dichlorethylene, chloroform, tetrachlorethane, or ethyl acetate. The shrinking agent may be diluted with benzene, toluene, xylene, benzine, petrol, kerosine, carbon tetrachloride, trichlorethylene, perchlorethylene, alcohols, glycerine, or water.  The filaments consisting of alternating shrunk and unshrunk portions may be doubled or made into woven or knitted fabrics with other filaments of the same type whether shrunk or not, or of another type such as cotton, wool, silk, or regenerated cellulose of the viscose, cuprammonium or nitrocellulose type.  The doubled thread, or the fabric, may be treated uniformly or locally with a shrinking agent to obtain differential shrinking.  Pebble or cockle effects may be obtained. The shrinking agent may be applied by passing the thread over a wick which is intermittently brought into contact with the thread. Alternatively, it may be applied by means of an embossed or indented printing roller.  The treatment may be combined with dyeing, printing, lustring, delustring, and other treatments.  Specifications 325,823 and 332,263, [both in Class 2 (ii), Cellulose &c.], are referred to.

The moulded article may be produced from a preform of two thermoplastic sheets which may be of a polyolefin having 2-10 carbon atoms, e.g. low- or high-density polyethylene or polypropylene, polyethylene terephthalate, nylon, a polysulphone, a polycarbonate, polyvinylchloride, polyvinyl acetate, polystyrene, cellulose acetate butyrate or cellulose propionate, which may contain 1-70% by weight of a filler, e.g. asbestos, aluminium oxide, glass fibre, carbon, calcium phosphate, calcium carbonate, clay, silica, titanium dioxide, bentonite, talc or mica. The sheets may be produced by extrusion, the surfaces thereof which are to form the interior interfaces of the preform being shaped to define the passageways by embossing or by the use of a serrated die. The passageways may be disconnected and formed by continuous parallel protuberances of rectangular cross-section of width less than the thickness of the sheet, or interconnected and formed by a regular pattern of island-like protuberances which may be rectangular or circular in plan. The sheets of the preform are bonded together in a manner such that they separate readily when fluid, e.g. air or other gas, water, molten polymer or liquid foam is introduced into the passageways, the bonding suitably being by ultrasonic spot welding, adhesive bonding, electrostatic bonding or thermal bonding. The preform 23 may be heated to the thermoforming temperature by radiant heating, dielectric heating, convection heating or by heated platens and placed between two opposing mould platens 27, 28, fluid being forced through passageway 32 through holes in sheet 24 into fluid passageways 30 between sheets 24 and 25 so that sheet 24 is distended into hollow cavities 29 in platen 28 which may have a roughened surface. The mould may have heating elements at the contact points on the mould and may be provided with two positions, one with the platens slightly apart at which fluid is introduced into the passageways and one where the mould platens are pressed lightly to each other to pressure seal the non-distended areas of the preform. Alternatively fluid may be introduced into the passageways by a vacuum technique. The mould platens may be arranged either horizontally or vertically.
