Abstract: 261,383. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). Nov. 10, 1925, [Convention date]. Thionaphthene derivatives. - Thionaphthene- 2 : 3-dicarboxylic acid anhydride is condensed with an aromatic hydrocarbon, or a homologue or substitution product thereof, in presence of an acid condensing agent such as aluminium chloride. The aroylthionaphthene carboxylic acids so obtained are converted by ring closure, for instance by means of aluminium chloride after transforming into their acid chlorides or by meansof sulphuric acid, into phthaloyl-2 : 3-thionaphthenes, of which the simplest is and which dye wool from the vat when unsulphonated, and from an acid bath when sulphonated. These phthaloyl-2: 3-thionaphthenes can be converted by means of glycerine and sulphuricacid into analogues of benzanthrone of the formula. The latter, when heated with an alkaline condensing agent, yield dyestuffs which dye cotton' from the vat. The following examples are given -(1) thionaphthene-2 : 3- dicarboxylic anhydrideis condensed with benzene in presence of aluminium chloride, the benzoylthionaphthene-carboxylic acid treated with thionyl chloride, and the acid chloride treated with aluminium chloride in carbon disulphide to effect ring closure; thephthaloyl-2 : 3-thionaphthene dyes wool in yellowshades from the vat : (2) 5-chlor-7-methylthionaphthene-2 : 3-dicarboxylic acid (produced from 5-chlor-7-methyl-oxythionaphthene in a similarmanner to thionaphthene dicarboxylic acid) is converted into the anhydride by boiling with acetic anhydride and similarly condensed with benzene, and ring closure effected by means of sulphuric acid; 2:3-phthaloyl-5-chlor-7-methyloxythionaphthene is thus obtained : from chlorbenzene and thionaphthene-2 3-dicarboxylic acid can be obtained a chlorphthaloyl-2 : 3-thioraphthene : (3) benzoylthionaphthene-carboxylic acid, treated with fuming sulphuric acid yields a phthaloyl-2 : 3-thionaphthenesulphonic acid thesodium salt of which dyes wool from an acid bath in yellow shades: (4) phthaloylthionaphthene is condensed with glycerol in presence of sulphuricacid and aniline sulphate; the benzanthrone-like body so prepared, upon caustic potash fusion, yields a dibenzanthrone-like body which dyes cotton in blue shades from a claret-red vat.

Abstract: 517,956. Artificial filaments &c. ; albumens. SOC. ANON. BREVETTI M. PIACENZA. Sept. 7,1938, No. 26155. Convention date, Sept. 18, 1937. [Classes 2 (ii) and 2 (iii)] - Animal proteins, fibroins and sericins, are subjected to trituration and grinding to a fine powder, and dissolved in phosphoric acid having a concentration greater than 80 per cent. by weight, in the ratio of about 9 parts by weight of solvent for 1 part of substance to be dissolved, with additions of cerium and thorium oxides on a support of aluminium and zirconium oxides crystallized in a single mass, in the ratio of 0.01 to 1 gram per litre of solvent, an addition of 2 per cent. calculated on the total weight of the mass, of lanoline dissoved in an alcoholic solution of trisodium phosphate, and then an addition of 2 per cent. of butyl stearate being made. Solution is effected at atmospheric temperature but not higher than 25‹ C. The viscous mass is filtered, ripened at 0‹ C. in a vacuum, and then coagulated by means of a solution of sodium chloride of about 25 per cent. strength followed by treatment with a solution of sodium chloride of the same strength but with an addition of 2 per cent. of an alkali formate. The mass is given the desired shape in the coagulating bath and it may be mixed with other body or filling substances. The products obtained are dried in an atmosphere of formaldehyde vapours and then washed. Instead of using two coagulating baths, a single bath may be used. Thallium oxide may be used in addition to or in substitution of the cerium or thorium oxide. For obtaining opaque products, calcium chloride or sulphate or a titanium salt may be added to the coagulating bath. The process may be used for the production of textile fibres by extruding or drawing the solution through or from a spinning jet. The filaments may be subjected to stretching. The filaments may be cut to short fibres. To obtain flat products, the solution may be passed between two cylinders arranged in the coagulating bath. Products of any desired shape may be obtained by passing the mass in the coagulating bath into moulds or dies. To obtain products of curled appearance similar to wool, the threads in skein form or after being cut to fibres are immersed in a solution of sodium or potassium bisulphite. The filaments or fibres may be mixed with cotton, hemp, or other natural or artificial fibres. The protein material may be horn, hooves, rags and shreds of silk, wool, skin, hair, or feathers. When the protein material contains no silk or wool, or only a small proportion of these materials, there may be used oxides of cerium and thorium without the support of aluminium and zirconium oxides, when forming.the solution.

Abstract: 978,975. Electric selective signalling systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 24, 1962 [July 24,1961], No. 26724/61. Heading G4H. In a shaft position digitising system four commutators, each producing a marking one one of ten leads, are geared together, and each, except the units commutator, has a pair of lead/lag brushes selectively controlled by the next lower commutator. The brush of the units commutator is sufficiently wider than the gaps between the conductive segments of the commutator, so that an output is always produced and this results in two leads being marked simultaneously during the transitions from one digit to the next. To compensate for this a circuit Fig. 9 is shown which produces a pure binary representation DEFG of the input lead 1 to 0 which is marked, the circuit being characterized in that the pure binary output DEFG always produces a representation corresponding to the higher of two marked input leads when two are marked. The outputs of the other commutators are also recorded to pure binary but no transitional difficulties arise (because of the lead/lag brushes) and a conventional diode network is used.
