Title: Improvements in the manufacture and production of artificial resins
IPC: C08G2/00
Filed: 1926-10-04
Abstract: 276,518. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 4, 1926. Coating-compositions. - Artificial resins produced by subjecting to alkaline neutral or acid condensation either mixtures of several cyclic ketones or mixtures of one or several cyclic ketones with aromatic or hydroaromatic hydroxyl compounds such as cyclic alcohols or phenols, may be used in conjunction with other natural or artificial resins or cellulose esters or ethers or natural or artificial caoutchouc to produce lacquers, films and insulating and other coatings and may contain filling masses such as saw-dust, diatomaceous earth, asbestos and the like. Mixtures of cyclohexanone with m or p methylcyclohexanone or both, or mixtures of several methylcyclohexanones which are obtainable by hydrogenation of purified industral cresylic acid, subsequent dehydrogenation and fractional distillation, or mixtures containing considerable quantities of cyclic hydroxyl compounds, such as the crude dehydrogenation product obtained by passing vapours of methylcyclohexanol over copper, may be employed. In examples (1) cyclohexanone is mixed with crude methylcyclohexanone obtained by catalytically dehydrogenating methylcyclohexanol without subsequent fractional distillation, and the mixture is boiled with a solution of caustic potash in methyl alcohol. After separation of the alcohol and alkali the resin is again heated until no oily liquid distils over; (2) a crude mixture of methylcyclohexanones and methylcyclohexanols obtained by catalytically dehydrogenating isomeric methylcyclohexanols is heated with a mixture of cyclohexanone and cyclohexanol obtained by catalytically dehydrogenating cyclohexanol and a solution of caustic potash in methanol. Higher cyclic ketones whether derived from hydrogenated benzene or naphthalene or their homologues may also be used. A product suitable for use as a lacquer is obtained by kneading together cellulose nitrate, caoutchouc and a resin obtained according to example (1) with ethyl alcohol and benzene and slightly heating to evaporate excess of the solvent; and a product suitable for coatings is obtained by mixing copal resin dissolved in linseed oil with the resin obtained according to example (2) dissolved in linseed oil, and turpentine oil or substitutes therefor, siccatives and the like are added. This product mav also be obtained by melting the copal resin with the artificial resins and dissolving them together with the above additions in linseed oil. Specifications 146,498 and 170,351, [both in Class 2 (iii), Dyes &c.], are referred to. Reference has been directed by the Comptroller to Specification 273,684, [Class 2 (iii), Dyes &c.].

Abstract: 719,004. Magnetic compositions; permanent magnets. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 1, 1952 [Oct. 4, 1951], No. 24591/52. Drawings to Specification. Classes 35 and 38(2) A magnetic material consisting of the non-cubic crystals of polyoxides of iron and at least one of the metals Ba, Sr, Pb and in some cases Ca, such as form the subject of Specification 708,127, is magnetized at a temperature substantially above or below room temperature in a magnetic field having a value lower than would be necessary to magnetize the material at room temperature to that intensity which the material actually assumes upon restoration to room temperature. The magnetizing field may be equal to less than the value of I<SP>H</SP>C at room temperature and a value not exceeding 700 Oersted may be sufficient. The temperature of magnetization may be between the Curie point and 0.8 times the Curie point in degrees absolute, or at a temperature below -50‹C, and magnetization may follow heating to above the Curie point. Annular magnets may be magnetized to an intensity not otherwise possible. The magnetization may be continued while the material is brought to room temperature. A magnet made from the material may be used at a temperature higher than room temperature at which I<SP>H</SP>C has a maximum value.

Abstract: 243,322. Boucher, J., and Boucher, A. Nov. 22, 1924, [Convention date]. Gathering molten metal.-A working- hole in a tank furnace, for use with a suction - gathering machine, comprises an opening through which the metal is gathered, and a shutter for uncovering and covering the gathering- opening, the shutter being adapted to admit hot gases to the surface of the metal at the gathering- opening during the time the opening is covered. The device is shown in sectional elevation in Fig. 1 and in plan in Fig. 2, and comprises a boxlike-member b of refractory material that is fitted in an aperture in the wall of the tank furnace T. The member b has an arc-shaped wall d in which an opening e is formed, and a floor in which the gathering-opening f is formed, the openings being adjacent to one another, as shown. The opening f is fitted with a potette g or other device for segregating an area of metal. The shutter consists of a hood-like member R which fits over the two openings and has a wing r that conforms to the shape of the wall d. It is mounted on a suitable frame which may rest on rollers, balls, or a race of some kind so that it can be swung about a centre a to uncover the opening f when a gather is to be made, and to cover it again when the gather is completed. When the opening f is uncovered by the hood R, the wing r covers the opening e. When the hood covers the opening f, hot gases from the furnace pass through the opening e, as shown in Fig. 1, and re-heat the surface of the metal in the opening f. In both positions of the hood R, hot gases are prevented from escaping from the furnace.
