Title: Improvements relating to iso-indolone dyes and their use
IPC: C09B26/02
Filed: 1957-07-12
Abstract: 3 - Imino - isoindole - 1 - ones containing at least three halogen atoms in the benzo radical are made by treating with ammonia or a primary amine the correspondingly halogenated 1 : 3 : 3 - trichloro - isoindolenines, which may be made from the corresponding phthalimide by reaction with 2 mols. of phosphorus pentachloride in absence of moisture, or by similar treatment of 3 : 3-dichloro-isoindole-1-ones containing at least three halogen atoms in the benzo radical.  The latter may be made by reacting at least one mol. of phosphorus pentachloride with the corresponding phthalimide or by hydrolysis of the corresponding 1 : 3 : 3 - trichloroisoindolenine.  The 3 - imino - isoindole - 1 - ones are also made by heating tri- or tetra-halogen phthalic acid anhydride in nitrobenzene with urea and ammonium molybdate.ALSO:The invention comprises coloured condensation products of the formula <FORM:0833548/IV(c)/1> where Hal is a halogen atom, R is a direct linkage when m = 0 or the radical of an organic compound of the homo- or hetero-cyclic aromatic series, the nitrogen atoms being directly bound to the aromatic nucleus of the radical, n is 3 or 4 and m is 0 or 1.  The invention further comprises a process for making coloured condensation products by condensing polyprimary amino compounds of the homo- or hetero-cyclic aromatic series or hydrazine with a molecular equivalent for every primary amino group thereof of the same or different isoindole-1-ones containing at least 3 halogen atoms in the benzo radical and containing in the 3-position an imino group which may be organically substituted, a doubly bound sulphur atom, two halogen atoms, two secondary amino groups or two ether groups.  Instead of an isoindole-1-one containing two halogen atoms in the 3-position, a 1 : 3 : 3-trichloro-isoindolenine may be used provided water is present. The polyprimary amino compounds mentioned include those derived from stilbene, naphthalene, anthraquinone, thiazoles, oxdiazoles and thiadiazoles.  Examples are given.  The condensation products colour synthetic polymers such as polyvinyl chloride, lacquers, rubber, viscose or cellulose esters in the mass, paper and cellulose and animal fibres.ALSO:A thin foil is made by mixing on a roller frame polyvinyl chloride, dioctyl phthalate, titanium dioxide, dibutyl tin dilaurate and a pigment having the formula <FORM:0833548/IV (a)/1> where R is the 3 : 31-dimethoxy-4 : 41-diphenylene radical.  A mixture comprising titanium dioxide, a 60% solution of a modified urea alkyd resin in xylene/butanol 1 : 1, turpentine oil and xylene and a pigment of the above formula, where R is the 4 : 41-diphenylene radical is milled in a ball mill, poured on to aluminium sheets and annealed.

Abstract: 935,227. Finishing yarns; twist-tubes. TEIKOKU JINZO KENSHI KABUSHIKI KAISHA. June 19, 1961 [June 29, 1960; Dec. 26, 1960; May 31, 1961], No. 22141/61. Classes 120 (2) and 120 (3). A false-twisting nozzle, as may be used for crimping yarn 1, comprises a tubular passage 8 and a fluid inlet tube 5 of smaller diameter than the passage and disposed in a direction tangential to the axis thereof. One end of the passage (from which the inlet tube is spaced) is constricted at 7 in order to minimize ballooning of the yarn being twisted, and the other end is wide open. Yarn is uniformly rotated or twisted by expanding and gyrating fluid, e.g air, in passage 8. Inlet tubes, as at 5, may be disposed in two or more locations, Fig. 4 (not shown). In the nozzles shown in Figs. 5 and 11, air from feed pipe 13 passes into a chamber 12 and thence, through tube or groove 5, into passage 8. In a modification, Fig. 7, air from pipe 13 is introduced, through a groove 5 of an annular plate 14 forming a tubular passage by union with annular pieces 8<SP>1</SP> and 8<SP>11</SP>, into passage 8: groove 5 may be such that the whole of the inlet tube assumes a curved shape or its foremost part may be of parabolic form, Figs. 9 and 10 (not shown), so that advance directional movement is imparted to the air and turbulence in the passage 8 thereby reduced. Combined heating and (insulated) twisting apparatus, Figs. 13 and 14, comprises an electrically heated tubular or U-shaped grooved yarn passage 23 projections, as at 22, or corrugations in which limit escape of air and reduce heat losses: holes 21 prevent heated air from passage 23 being drawn into nozzle 8. Specification 871,112 is referred to.

Title: Twisted ribbon superconductor
IPC: H01B12/08
Filed: 1973-05-11
Abstract: 1401368 Super-conductors; electromagnets NATIONAL AERONAUTICS & SPACE ADMINISTRATION 11 May 1973 [11 Aug 1972] 22506/73 Headings H1A A5 and A4D A twisted ribbon super-conductor comprises a flexible substrate 10 around which is formed at least one helical layer 22 of a super-conductive compound. As described, all surfaces of a niobium ribbon substrate are coated with a masking metal (copper or nickel) which is then selectively removed by photo-etching to expose helical paths. The substrate is heated in an oxidizing atmosphere at 200-500C to form a final mask of niobium oxide 20 in the helical paths. The remaining masking metal may now be removed and the substrate is subjected to a diffusion reaction to form layers 22 of niobium stannide. To effect this the substrate is dipped in molten tin, removed but held at high temperature, and then allowed to cool. If the intermediate mask is of copper it need not be removed before the treatment with molten tin: copper is not found in the final ribbon. When coating with copper, a first thin layer is vacuum deposited and then built up by electro-plating. In a modification, a plating resist mask is formed as the first step, and the intermediate mask is then applied by plating.

Title: A method of decorating cellulose materials
IPC: B44C1/20
Filed: 1930-07-25
Abstract: Designs are produced on sheet material having a base of cellulose acetate or other cellulose derivative by applying the material by means of a roller to the surface of a glass plate provided with a design comprising two or more depths of engraving, a solvent of the cellulose material being interposed between the sheet and the plate. The surface of the glass plate may be initially smooth or rough, and the design may be formed by cutting, or by coating the plate with a resist, removing parts of the resist, and etching, the operation being repeated to provide the different depths required. Alternatively, the engraving may be produced by sand-blasting, employing a resist or stencils, or by applying a layer of glue which is allowed to set, and, when stripped off, pulls away parts of the glass.  The plate covered with the sheet material is heated to accelerate the evaporation of the solvent and to dry the material, which is then peeled off the plate.

IPC: A23L29/231
Filed: 1962-06-14
Abstract: As dressing for food such as pancakes, waffles and ice-cream is employed a pourable oil-in-water emulsion containing a flavouring ingredient, an edible oil in amount forming 1-40% by weight, and, as emulsion stabilizer, a water-dispersible protein, gum arabic or an edible algin derivative, at least 65% by weight of the aqueous phase of the emulsion being a sugar.
