Abstract: 1,001,512. Transformers. ENGLISH ELECTRIC CO. Ltd. Nov. 20, 1961 [Nov. 24, 1960], No. 40400/60. Heading H1T. An electric transformer having a high voltage winding of the pancake type (Fig. 1) whereof at least one pair of adjacent sections such as A 1 , B 1  near the high potential terminal E has wound, at least between some of the outer turns, conductors H and I insulated from the winding current path, the sections being connected in series at F and the conductors being connected together at j. The conductors may be of copper or aluminium foil or formed of conductive metal sprayed on an insulating carrier. The foil increases the series capacitance of the windings off-setting a voltage build-up between the coil turns and forming with them a non-inductively wound capacitor. For windings comprising several sections (Fig. 4, not shown) the number of turns of conductors H and I may be graduated to extend further inward of the winding at the high potential end than at the low potential end. In an embodiment, Fig. 5, the winding comprises a pair of conductors 1, I<SP>1</SP>, 2, 2<SP>1</SP>, 3, 3<SP>1</SP> &c. connected in parallel and wound together with the foils H, I wound between pairs of turns of the winding conductors. In another arrangement (Fig. 6, not shown) a pair of windings of metal foil is used where one winding separates the individual turns of each conductor pair and the other separates the consecutive turns of the conductor pair. Other winding arrangements of the foil with parallel connected winding conductors are described (Fig. 7, not shown) and a modification in which the foils H, I of adjacent sections may be connected through external capacitors or other impedance devices included in the connection designated J in the Figures, is mentioned.

Title: A process for the production of water-resistant paper or non-woven fabric
IPC: D21H13/16
Filed: 1969-08-13
Abstract: 1283405 Paper KURARAY CO Ltd 13 Aug 1969 40550/69 Headings D1R D2B Paper or non-woven fabrics containing a water-soluble polyvinyl alcohol which dissolves in water at 95‹C or below is treated with an aqueous solution of α-titaric acid having a Ti concentration of 0.2-5% by wt in 1.3-14% HCI or 0.7% or more H 2 SO 4 , at 40‹C or below. The polyvinyl alcohol may be present as the main fibrous component, as a fibrous binder, or as a non-fibrous binder. The paper may be formed mainly of polyvinyl alcohol, nylon, polypropylene, polyester, rayon, wood pulp or cotton bast fibres. The solution of α- titaric acid may be prepared by adding TiCl 4  to water, or by dissolving, in a mineral acid, the precipitate formed when ammonia is added to the solution formed when TiCl 4  is added to water. The α-titaric acid may be stabilised by addition of a water-soluble alcohol e.g. methyl, ethyl, normal or iso-propyl, normal, iso- or neo-butyl, amyl isoamyl alcohols, ethylene glycol, 1,2 propylene diol, glycerine, pentaerthritol or polyvinyl alcohol. These alcohols may be added in an amount 2-7% of the treatment solution. Polyvinyl, alcohol is dissolved in water before addition to the α-tataric acid solution, to give a solution 3% by wt or below, which is then slowly added with agitation to the acid solution which should be of less than 5% concentration. Polyvinyl alcohol solutions of completely hydrolysed polyvinyl acetate, partly hydrolysed polyvinyl acetate, partly hydrolysed polyvinyl esters and polyvinyl acetates are obtained by partial condensation of polyvinyl alcohol. There also exists a relation between the titanium and mineral acid concentrations, and the stability of solution, and suitable concentrations may be chosen to allow a more stable solution to be given. Polyvinyl alcohol non- fibrous binder may be applied in the headbox of a paper-making machine, or to the formed web. Similarly, such binder may be incorporated into the non-woven fabric either at the feeder, or to the formed fabric. Non woven fabrics may be formed by carding or by air laying and may be needled. Polyvinyl alcohol binder may be mixed as powder with the fibres before air laying, supplied as heat fusible binder fibres or applied as an aqueous solution to the web. After treating with titaric acid the web containing polyvinyl alcohol fibres may be bonded by immersion in boiling water.

Abstract: 959,895. Glass melting furnaces. BRITISH GLASS INDUSTRY RESEARCH ASSOCIATION, and G. R. MATTOCKS. Nov. 30, 1961 [Nov. 30, 1960], No. 41218/60. Heading F4B. In a furnace for the heating and at least partial reaction of glass making materials a reaction chamber is energized by pulsating combustion and means are provided for introducing the glass making materials into suspension in the reaction chamber. The reaction chamber is designed to support a standing wave which is energized as a result of pulsating combustion occurring in suitably designed barrier units communicating with the said chamber. In the form shown a main reaction chamber 1 in the form of a cylinder is constructed of refractory material and divided into two parts A, B, each being closed at its outer end. At a distance of approximately one quarter of the wavelength of the standing wave from the closed ends a set of radially spaced pulsating combustion units 6 communicates with the interior of the cylinder. These units 6 are made up of a combustion zone chamber 7 and a diffuser 8. Fuel, e.g. oil or gas, is fed into the pulsating combustion units by lines such as 9, 10, and the air is supplied through lines 11 and 12. Air is also supplied tangentially through inlets 13, 14 to produce a swirl effect in the reaction chamber, which has an annular recess 15 in its internal wall at the velocity nodal points, to encourage swirled particles to collect and then, aided by the raised portions 2 of the floor of the reaction chamber, to discharge into corresponding outlets 3 provided with auxiliary heating electrodes 4 for sustaining the particles, now in the form of a viscous melt, in a fluent state. The outlets 3 lead via ducts 3<SP>1</SP> to a common channel 5 leading, for example, to a glass refining unit. An exhaust chimney 16 is provided with tangential inlet tubes 17 for a diluent cooling fluid and also a cyclone for the final precipitation of any entrained solids. The glass making materials are fed in partly through the combustion units 6 at 18 and partly by direct introduction into the reaction chamber. Silica and calcium carbonate constituents being fed either separately to individual combustion units or as a mixture. The alkali component of the batch, e.g. the sodium carbonate, is preferably introduced by separate inlets 19 in the reaction chamber, so that premature reaction between the glass making materials in the diffuser 8 is precluded. In a modification the reaction chamber is of an annular form.

Title: Improvements in a process for removing soot from gases
IPC: C10K1/04
Filed: 1958-12-29
Abstract: 851,655. Removing soot from gases. BATAAFSCHE PETROLEUM MAATSCHAPPIJ N.V., DE. Dec. 29, 1958 [Dec. 31, 1957], No. 41866/58. Drawings to Specification. Class 55 (2). In a process for removing soot from a hot soot-containing gas, e.g. a gas containing carbon monoxide and hydrogen produced by the partial combustion of hydrocarbons, water is sprayed into the hot gas cooling the gas to a temperature which is less than 40‹ C., preferably less than 10‹ C., below the dew point of the mixture of gas and water vapour thus produced and the resulting soot-in-water suspension and entrained water is removed from the gas, steam is then added to the washed gas and by further cooling any remaining soot particles are removed. The further cooling may be indirect or be by spraying the gas with water. If the gas is initially at a very high temperature it may be passed through a waste heat boiler to cool it to a temperature of e.g. 250‹ C. The process is preferably carried out at a pressure of at least 5 atm. and preferably between 10 and 30 atm. In an example hot gas leaves a gas generator at 1300‹ C. and is cooled in a waste heat boiler to 250‹ C. before being scrubbed with water at 30‹ C., the temperature of the gas being reduced to 140‹ C. Steam is added to the gas after it leaves the scrubber and the gas is cooled indirectly to 20‹ C.. The final gas contained 1 grain of soot per 1000 kilogrammes of dry gas. Specification 826,209 is referred to.

Abstract: 1,184,969. Bridge circuits. SOLARTRON ELECTRONIC GROUP Ltd. Sept. 3, 1968, No.41914/68. Heading G1U. An A. C. bridge has two adjacent arms comprising synchronised sources of alternating voltage -V/A and +kV/B whose ratio is adjustable but independent of the load imposed by the remaining arms, a third arm comprising a standard reactance or resistance S1 and a fourth arm with terminals for connection to an unknown reactance or resistance X. A detector arm connected between the junctions of the first two (at Earth 61) and third and fourth arms 63 provides an output (amplified at 65) to two phase detectors 67, 69 synchronized with the sources for detecting the balance of the bridge relative to the main parameter being measured and its quadrature component respectively. The first detector controls arrangements 71, 49, 43a for automatically adjusting the source voltage ratio to balance the main parameter, while the second detector controls an arrangement for feeding an opposing current of variable amplitude into the detector arm with the same phase as the quadrature component to balance it out. The arrangement controlled by the first detector 67 incorporates a level descrimator 71, control unit 49 and switching and transformer unit 43a as described in Specification 1,160, 834. The arrangement controlled by the second detector 69 incorporates a modulator 102 comprising a lamp 104 whose brightness is controlled by the detector output to vary a photo-resistor 105, which controls the amount of current fed via amplifier 101 to balance out the quadrature component. The system shown is for measuring a capacitance X, and the main phase detector 67 will measure in quadrature with the supply. Loss factor may be determined by changing the position of the switch 101 and adjusting the resistor 75. To measure resistance, the detectors 67, 69 will be in phase and in quadrature with the supply respectively, and the resistor 73 in the current feedback path will be replaced by a capacitor.
