Title: Improvements in and relating to coil spacers for stationary electrical induction apparatus
IPC: H01F27/30
Filed: 1951-10-04
Abstract: 685,829. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 4, 1951 [Oct. 7, 1950], No. 23136/51. Class 38 (ii). A stationary electrical induction apparatus having a plurality of disc-type coils 10 stacked in superposed relation has radial spacing members 12, each member extending across both sides of a given coil, the member having at least two arms as 18, 19 on each side of the coil meeting in a common apex on each side of the coil and which are connected by a distancepiece 20, at least one of the arms being apertured, as at 21, to permit liquid to flow therethrough. Two embodiments are shown, one in which the spacing members are V-shaped as in Fig. 3, the other in which they are W- shaped (Fig. 4, not shown). With spacing members of this type optimum support is given to each coil at both the inner and outer edges without the spacing members being overcrowded at the inner edges. Usual spacing members 27 may be interposed between these members for additional support, if desired. Cooling liquid enters the casing 1 by means of a conduit 13 and passes up through an opening in the outer edge of a diaphragm 14. The liquid then passes radially inwards across the four lowermost coils 10 and then passes upwardly through an aperture in the inner edge of a diaphragm 15. In the next tier of disc coils the liquid flow is radially outwards. Thus a " zig-zag " type of liquid flow across the coils is obtained, the liquid eventually leaving the casing by a conduit 28 whence it may then be conducted to any suitable cooling means. Specification 675,744 is referred to.

Abstract: 937,576. Supply systems for cinematograph projector lamps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 15, 1962 [June 27, 1961], No. 23227/61. Class 38 (4). The high pressure, xenon-filled, cold cathode lamp 3 of a cinematograph projector is supplied with pulses of energy from the terminals 1, 2 of a D.C. source by applying alternate signals of opposite polarity to the control electrode 6 of a semi-conductor rectifier 5, which is thereby made conductive or non-conductive at the frequency of the pulses to be supplied. The rectifier 5 may have two control electrodes to which switching-on and switching-off signals are applied respectively. A resistor 4 maintains a small discharge through the lamp between pulses of current. The signals applied to the rectifier 5 may be obtained by arranging for the flicker shutter of the projector (or a member associated with this shutter) to periodically interrupt a beam of light impinging on a phototransistor, whose output is converted into pulses of alternating polarity by a conventional amplifier, phase-splitter and differentiator circuit, Figs. 2 and 3 (not shown) Alternatively the signals may be produced by associating with the shutter a magnetically-cored inductance so that the leading and trailing shutter edges produce a signal through the winding associated with the core. If the flicker shutter is omitted the signals may be supplied by means moving synchronously with the movement of the film through the gate.

The discharge device may also be a gear pump or a rotary pump ; it may exert substantial suction at the inlet of the housing and pressure at the outlet end. The device may exert a kneading effect on the butter. The butter may be delivered intermittently in conjunction with a packaging machine. Fig. 4 illustrates discharge of butter from the container 10 to a packaging machine 26 by means of a rotary pump 30.

Abstract: 811,745. Liquid fuel burners. DAIMLER BENZ A. G. July 27, 1956 [July 30, 1955], No. 23357/56. Class 75(1) [Also in Groups XII and XXVI] In combustion equipment for a gas turbine engine or jet propulsion unit, fuel is supplied through rotating nozzles or supply passages into a stream of primary air against a wall which is heated directly by the combustion gases within the combustion chamber being thereby vaporized, the mixture of vaporized fuel and primary air being led into the combustion chamber and burned with the addition of secondary air. The gas turbine jet propulsion engine shown comprises a compressor 11 and turbine 12 mounted on a common shaft 10, annular combustion equipment 15 and an outlet 23 to a propulsion nozzle. The inner wall 13 of the combustion space is disposed around the shaft 10 to provide an annular passage 14 through which primary air flows, the wall 13 terminating at its downstream end in a flared portion which is surrounded by a correspondingly-shaped wall 18 which forms the downstream portion of the inner wall of the combustion chamber. Fuel flowing through the duct 24 in the rotor shaft 10 issues through outlets 25 and impinges on the inner surface of the wall 13 which is heated on its outer surface by combustion gases in the chamber 15, the fuel being thereby vaporized. Further fuel issues through the outlet 26 and impinges on the wall 18 and is also vaporized. The mixture of vaporized fuel and primary air reverses in direction and enters the combustion space in an upstream direction. Some of the air flowing through the diffuser 16 enters the combustion space directly and constitutes the secondary air. A row of rotating swirl vanes 20 is disposed at the entrance to the annular passage 14, and a row of fixed swirl vanes 21 at the outlet therefrom. A row of fixed swirl vanes 22 is disposed in the path of the secondary air flow into the combustion space.

Abstract: In the resist-printing of textile materials consisting of or containing non-cellulosic fibres, e.g. cellulose acetate, wool, silk, nylon and perlon, a water-soluble aldehyde, e.g. formaldehyde, or a substance, such as hexamethylene-tetramine, which yields such an aldehyde on heating, is applied to the material in selected areas either before or after the material has been impregnated with a vat dyestuff and thiourea dioxide, whereby on subsequent drying, ageing with saturated steam at a temperature of about 100 DEG C. and oxidizing, those areas of the material where the aldehyde is applied or liberated remain substantially uncoloured.  Coloured resist effects may be obtained by the addition of suitable dyestuffs, e.g. "Soledon" (Registered Trade Mark) dyes, pigment suspensions, dispersed acetate dyes and acid wool dyes, to the aldehyde printing paste. Examples of the process applied to cellulose acetate and woollen materials are given.

Title: A process for the preparation of anhydrous aluminium fluoride
Inventor: THOONEN THEODORUS JOHANNES
IPC: C01F7/50
Filed: 1967-05-24
Abstract: Anhydrous AlF3 is made by reacting an aqueous solution of NH4F with at least 1.9 times the amount of Al2O3 or its hydrate required to form (NH4)3 AlF6, separating the resultant mixture of tri-ammonium hexafluoroaluminate and unreacted alumina and drying and heating it to a temperature between 400 DEG  C. and the melting point of the mixture. The first step may be effected in an ammonical solution at 65-125 DEG  C. in a closed vessel.  The precipitate, which need not be washed, is preferably heated gradually or stepwise to 480 DEG -550 DEG  C. over a period of at least 20 minutes when a metastable form of AlF3 is formed.  Faster heating gives the stable form.
