Title: Improvement in electric condenser
IPC: H01G9/022
Filed: 1928-11-23
Abstract: 311,727. Ruben, S. May 15, 1928, [Convention date]. Condensers comprise plates of metal having film-forming properties, and material between three plates, the material being adapted under electric stress to yield ionic components which react with the plates to provide the dielectric. Suitable metals are calcium, magnesium, aluminium, and zinc. A plate 11 disposed along a mandrel 10 forming part of the finished condenser, is thinly and evenly covered with a film-forming material 12 supported by a piece of fine muslin 13. A second plate 14 is then placed over the whole, and the condenser is wound about the mandrel and provided with terminals such as 11<1>. An electrolyte suitable for reaction in the solid state with the metal without the aid of free moisture is an over-saturated metallic oxide such as lead peroxide, vanadium pentoxide, or magnetic oxide of iron, or other compounds of the sixth group in the Periodic Table of Chemical Elements. Magnetic oxide of ircn is particularly mixed with aluminium or zinc plates, and is preferably mixed with an inert binder such as borax or boric acid up to 30 per cent of the whole. To form the dielectric, alternating-current is passed through the condenser. Numerical data are given in the Specification.

Title: Friction elements
IPC: F16D69/02
Filed: 1974-08-09
Abstract: 1451864 Carbon elements JURID WERKE GmbH 9 Aug 1974 [9 Aug 1973] 35263/74 Heading C1A [Also in Divisions C4 and F2] A friction element comprises a friction layer, wherein the friction layer has a porous structure and is made of industrial carbon. The entire friction element may be made of industrial carbon or the friction layer may be secured to a support, e.g. a metal plate. The industrial carbon is prepared by freeing cokes, anthracites, carbon black and other forms of carbon from volatile constituents, e.g. by heating at about 1000‹ C. with the exclusion of air. The product is ground and screened and selected granular fractions are compounded into a hot plastic mixture with the addition of molten hard coal tar pitch. This mass is shaped and subjected to a baking process at 1000-1400‹ C. During the baking the articles are embedded in coal dust or grit to protect the material from oxidation and deformation. The uniform baking process extends over several weeks and the ultimate product is "baked carbon". This may be converted to "electrographite" by a further heat treating process using a final temperature of 2700-2800‹ C. These forms of industrial carbon are in the form of plates, bricks, tubes, cylinders, rods or blocks of high pore volume from which the friction layer may be cut or sawn. The friction elements may be used as plates in dry running clutches or oil immersed clutches.

Abstract: 621,492. Radiolocation. SPERRY GYROSCOPE CO., Inc. Aug. 16, 1943, No. 35274/45. Convention date, April 30, 1942. Divided out of 621,485. Drawings to Specification. [Class 40 (vii)] In a radiolocation system, range is determined by generating a train of reference pulses and adjusting their phase by means of a phaseshifter until they are in phase with the received reflected pulses when the setting of the phaseshifter gives the range. The reference pulses are applied to a type-A cathode-ray tube indicator in the form of a pedestal pulse or a stepped wave, so as to shift the selected reflected pulse relatively to adjacent pulses. The invention is described with reference to a system identical with that described in Specification 621,485. Specifications 582,279, 582,492 and 610,704 also are referred to.

Abstract: 361,629. Indicating liquid levels. MAHON, H. G. B., Northlands, Spital Terrace, Gosforth, Northumberland, and HOPKINSONS, Ltd., Britannia Works, Huddersfield. Nov. 28, 1930, No. 35805. [Class 123 (i).] In gauge glasses of the reflecting prism type, the effects of erosion of the glass and of double reflection are minimized by exposing a flat or plane face of the prism to the liquid, the inclined faces being external faces. The gauge comprises a metal body a, Fig. 3, having a channel b for the liquid. A plane face e of the prism seals the liquid channel, and light passing through the inclined face f is reflected at the surface e above the liquid level, and is viewed through the face g. Light reaching the surface e below the liquid level is refracted into the liquid and that part of the prism therefore appears dark. The prism is clamped in position by a bar i. In a modification, Figs. 4 and 6, the prism is provided with transverse corrugations on the outer face, the path of the light rays being shown at A, B, Fig. 6. In Fig. 8, the corrugations are arranged longitudinally, and the reflection of light rays is across the gauge.
