Title: Improvements relating to electrical capacitors and to processes for their manufacture
IPC: H01G2/24
Filed: 1963-05-08
Abstract: 974,720. Capacitors. SIEMENS & HALSKE A.G. May 8, 1963 [May 9, 1962; Oct. 4, 1962], No. 18129/63. Drawings to Specification. Heading H1M. A process for the manufacture of capacitors of the flattened roll-type wherein synthetic dielectric sheet or strip material together with metal film are coiled to form a roll which is pressed to the desired shape, includes the step of applying a pressure to the roll of such magnitude that plastic flow of minute surface projections of the dielectric material occurs without resulting in plastic flow of the other parts of the dielectric surfaces. The dielectric may be polyethyleneterephthalate or polycarbonate having surface projections between 0.1 and 1 micron in height and preferably coated with a metal film by vapour deposition. The rolls may be subject to a pressure of 2000 atmospheres at room temperature for a time between 1 second and 1 minute so as to cause valence binding to occur between adjacent dielectric convolutions so that the roll retains its shape. At a temperature of 140‹ C. the required pressure is only 1000 atmospheres. The roll may be heated, preferably by means of eddy currents induced in the metal foil, either before, during, or after the application of pressure. The pressure need not be applied over the whole surface area but may be applied to selected areas which may be arranged in a pattern; the total area to which pressure is applied is preferably between a quarter and two-thirds of the total area. When the dielectric material is stretched, it is preferably treated, e.g. by annealing, so that it is partially relaxed in the temperature range over which the capacitor is designed to operate. This may be done whilst the material is still on the supply roll, or after metallizing and cutting the material, or after winding the capacitor roll, but before pressing.

Abstract: 289,418. Rosenheim, A. April 27, 1927, [Convention date]. Right to Patent relinquished. Purifying liquids. - Adsorbents for dissolved substances are obtained from silicic acid sols or gels by adding to them in the presence of water salts of aluminium, iron, magnesium or titanium or mixtures thereof, causing a gel to form when a sol is used, separating the gel from the liquid, purifying the gel by washing as with an acid before or after complete or partial drying, and finally drying the purified gel. Alternatively, a gel mixture of silicic acid with the oxides of aluminium, iron, magnesium or titanium or mixtures thereof, prepared for instance from a mixture of their sols, mav be treated with an acid to extract the alumina &c. as a salt which is caused to act upon the remaining silicic acid gel, and the latter be then separated and purified as above described. According to examples :-To a sol obtained by treating an artificial zeolite with hydrochloric or sulphuric acid is added one of the salts above described. The gel formed by allowing the mixture to stand is separated from liquid, dried at 50-200‹ C. or at 270-330‹ C.. treated with water or dilute hydrochloric or acetic acid and again dried, it may be by gases such as air, carbon dioxide or monoxide, or nitrogen. A sol obtained by treating waterglass with hydrochloric acid is similarly treated. A mixed sol produced by treating a sol obtained from waterglass with aluminium chloride followed by sufficient dilute alkali to produce alumina from the chloride is converted into a gel, the alumina being then extracted by acid and the aluminium salt so obtained allowed to act on the remaining silicic acid gel. The gel is separated and purified as above described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter :-The preparation of sols from natural or artificial zeolites and their conversion to gels without separation of the electrolytes formed simultaneously with the sols; and the use, as electrolytes to be added to sols or gels, of cupric or manganese salts, and of acetates, formates or nitrates.

Abstract: 534,613. Aerial bombs. IMBER, J., and HEBARD, H. C. June 27, 1939, No. 18702. [Class 9 (i)]  An aerial bomb, which after striking the ground rebounds before bursting, has a striker impelled into engagement with a resilient locking device when the bomb is retarded on impact, the striker spring being compressed until after a certain retardation of the bomb when the spring reacts to unlock the striker and move it to fire the rebound propellant charge. In the form shown, on impact, penetration is delayed by a rubber or soft metal 'nose 3 and a spring striker 12 moves downwards to engage its rounded end 20 in a central spring hole in a disc 26. A ball 21 preventing firing movement of the striker is meanwhile released. The striker is thus held until retardation is sufficiently reduced when the reaction of its spring 15 releases the end 20 of the striker from the disc and impels the striker upwardly to fire the rebound propellant charge 8. The parts 1, 6 of the bomb are then detached and discharged upwardly from the nose portion 3, and the bursting charge of the bomb is fired at a distance above the ground under the action of a time fuze ignited on impact or by the explosion of the propellant charge.
