IPC: H01G4/22
Filed: 1958-10-22
Abstract: 902,574. Capacitors. SIEMENS & HALSKE A.G. Oct. 22, 1958 [Oct. 23, 1957], No. 33810/58. Class 37. A self-heating capacitor has a dielectric which includes a diphenyl in which at least a part of the hydrogen is substituted by fluorine and advantageously may include a further hydrocarbon in which at least a part of the hydrogen is substituted by fluorine, oxygen, nitrogen, or chlorine. Such materials have an asymmetrical molecular structure and their insulating properties are not impaired to any appreciable extent during self-heating. Polytetrafluoroethylene may be used as the dielectric proper of polymonochlorotrifluoroethylene as an impregnant in, for example, paper. The dielectrics are metallized by aluminium deposited from its vapour phase.

Abstract: 448,111. Valve circuits. COSSOR, Ltd., A. C., and BEDFORD, L. H., Cossor Works, Highbury Grove, London. Nov. 28, 1934, No. 34205. [Class 40 (v)] A pair of deflecting-plates Px1, Px2 in a cathode-ray tube for television is supplied with symmetrical detecting-voltages from an unsymmetrical circuit. The output from a relaxation oscillator is connected through a condenser Cx1 to the deflecting-plate Px1 and through a capacitative potential divider C2, C3 to a phase-reversing valve V3, the anode of which is connected through a condenser Cx2 to the opposite deflecting-plate Px2. To economize current, the valve V3 is of high impedance and the anode resistance R3 has a very high value. Consequent frequency distortion is compensated by inserting a resistance R1 in series with the potential divider such that the time constant C3, R1 is equal to the time constant of the circuit causing the distortion.

Abstract: 487,311. Safety devices for engines. ONIONS, J. W., and RUSTON & HORNSBY, Ltd. Dec. 15,1936, No. 34390. [Class 122 (iv)] The safety device, signal or alarm, comprises a body or casing with a plunger upon which the pressure of the lubricating oil and/or cooling water of an internal-combustion engine acts at one end against the action of a spring, and includes means for sliding the plunger to an inoperative position during starting, which means is rendered inoperative automatically when the lubricating-pressure &c. rises. The plunger may act as fuel-supply valve or control an electric contact to give a visual or audible signal, or both. If it is not desired to stop the engine, the fuel ports are dispensed with. The sliding plunger may be connected through a two-armed lever with two separate plungers operated upon by the lubricating oil and cooling- water respectively. The casing 1 has a fuelcontrol plunger valve 3 and a port 4 which connects ports 5, 6 in the fuel line. A spring 7 acts on the top of the plunger. Lubricating- oil or cooling water is supplied at 10. A leak passage 11 permits leakage fuel to return to the supply. A hand-operated cam 15 is arranged on a spindle 13 at the bottom of the casing. The plunger 3 is raised at starting by the cam 15 attached to the handle 19 to keep the fuel line open. When the lubricating &c. pressure rises the handle drops by gravity to the vertical position. A rod secured to the top of the valve 3 may operate an alarm when the lubricating oil or cooling water pressure has dropped a predetermined amount.

Abstract: 1,159,244. Pipes; rotational casting. AMERICAN PIPE & CONSTRUCTION CO. 1 Aug., 1966, No. 34392/66. Heading B5A. [Also in Divisions C1, C3 and F2] Articles, particularly pipes, are made by rotational casting of compositions comprising a curable furfuryl alcohol resin and 4 to 12 parts by weight per part of resin of a granitic aggregate containing both coarse and fine particles, and optionally an acidic curing catalyst. The mixture may be fed by a screw feeder to the interior of a rotatable pipe form and vibrated, screeded or rolled therein, whereafter the speed of rotatation is increased until a layer of resin not exceeding 1/8 inch is formed inside the pipe casting. The speed of rotation is then reduced and the inside of the casting trowelled if desired. The pipe may then be cured by heating, e.g. externally by infra-red heaters and internally by hot air blowers, during slow rotation. Further cure at the same or higher temperature may be effected after removal from the form.

Title: Improvements in or relating to the manufacture of polyvinyl acetals
Inventor: MAYNE JOHN EDWIN OAKLEY
IPC: C08F8/28
Filed: 1954-12-03
Abstract: Polyvinyl acetals are prepared by adding an aldehyde containing at least two carbon atoms to the final reaction mixture obtained by the hydrolysis of a polyvinyl ester in accordance with the process of the parent Specification.  The acetalization is carried out in two stages initially at a temperature below 45 DEG  C., preferably below 25 DEG C., then above 45 DEG  C. for example 60 DEG  to 65 DEG  C. to complete the reaction.  Small amounts of a strong acid such as sulphuric acid may also be present during the acetalization. In examples, polyvinyl acetate emulsion hydrolysed to give 15% to 2% residual acetate groups, in the presence of a napthalene-2-sulphonic acid catalyst is cooled to about 10 DEG  C. Butyraldehyde is added with stirring and after one hour the temperature is raised to 25 DEG C. for one hour and finally to 60 DEG  C. for three hours and the butyral washed and separated in the form of a fine granular dispersion.  The resin may be stabilized by treating with dilute alkali at 80-90 DEG  C. and washed and dried. Specification 621,784 is referred to.

Abstract: 619,251. Combustion chambers for gas turbines. MORDELL, D. L. Nov. 27, 1946, No 35230. [Class 51 (i)] A fuel spray from a nozzle 15 induced by compressed air is directed up-stream and impinges on a baffle 13 which deflects it downstream. Combustion air enters the flame tube 11 around the edge of the baffle and past swirlproducing vanes 22. Combustion takes place in the outer down-stream current and preheats the spray on its way towards the baffle. Secondary air passes around the flame tube and through a perforated plate 25. Additional primary air inlets may be provided in the baffle. The flame tube may be omitted and the baffle extended towards the wall of the combustion chamber 10. The air is taken from the main compressor and further compressed in a pump 19. Or, the air may be taken from the compressor at a high velocity and its pressure raised in a diffuser. Fuel may be mixed with the air in the pump 19. With an annular combustion chamber, a circular arrangement of spray nozzles or an annular spray nozzle may be used in conjunction with an annular baffle. Or, an annular combustion chamber may house a circular assembly of flame tubes.
