Abstract: 547,189. Emulsifying agents; textile lubricants. NATIONAL OIL PRODUCTS CO. Feb. 14, 1941, No. 2012. Convention date, Jan. 26, 1940. [Classes 1 (i) and 91] [Also in Group IV] High molecular products probably having an ester-amide structure are obtained by the condensation of aliphatic hydroxy mono-carboxylic acids containing at least 6 carbon atoms, or an ester, halide or anhydride thereof, with an aliphatic monocarboxylic acid containing from 6-22 carbon atoms but no reactive halogen atoms or an ester, halide or anhydride thereof, and reacting the product with an aliphatic amine containing not more than 22 carbon atoms or with urea or a substituted urea, both reactions being effected at a temperature above 100‹ C. The products have surface active properties and may be employed as defoamers, textile lubricants and softeners, for fat liquoring, waterproofing and softening leather, as plasticisers and softeners, as de-emulsifying agents, as flotation agents and wax substitutes. They may be treated with sulphating, phosphating and borating agents to give wetting and emulsifying agents and dyeing assistants. When polyamines are used the. products may be solubilized by treatment with acids e.g. lactic and acetic acids. In examples: (1) castor oil, coconut fatty acids and monoethanolamine or diethylenetriamine are condensed: (2) castor oil fatty acids are condensed with abietic acid and monoethanolamine : (3) hydrogenated castor oil, oleic acid and diethylenetriamine or ethanolethylenediamine are condensed : (4) castor oil is condensed with stearic acid and diethylenetriamine. Other components which are specified are: 12- hydroxystearic acid, hexanol-4-carboxylic acid, nonanol-7-carboxylic acid-1, koeme oil, ricinoleyl chloride, blown unsaturated oils, sabinic acid, erucic, ricinoleic, and oleic acid, methyl oleate, ethyl stearate, stearyl chloride and caprylic anhydride. The following amines are also mentioned: diethanolamine, isopropanolamine, tetraethylene-pentamine and isobutylamine. The Specification as open to inspection under Sect. 91 comprises also the condensation of the aliphatic hydroxycarboxylic acid with any monocarboxylic acid containing from 6-22 carbon atoms and any amine containing not more than 22 carbon atoms, in any order. In place of the amine, ammonia or thiourea or its derivatives may also be used. The use of benzoic, naphthoic and nicotinic acids and aniline, cyclohexylamine, degraded proteins and N-methylthiourea is mentioned.

Filed: 1967-01-17
Abstract: 1,133,421. Spring motors. VENNER Ltd. 5 Oct., 1967 [17 Jan., 1967], No. 2391/67. Heading F2S. [Also in Division G3] A bimetallic strip, according to the strength of an electric signal passing therethrough, either permits a mechanical spring drive to operate or prevents it from doing so. The spring drive may constitute a reserve spring drive in a clock normally driven by a synchronous electric motor. The balance wheel 12 of such reserve spring drive is held against movement by a lever 13 engaging a stop pin 16 thereon when a bimetallic strip 20 is heated by current supplied therethrough via leads 24, 25 from a secondary winding wound within the motor coil, or from a secondary winding of a transformer in series with the motor coil. The bimetallic strip 20 responds to changes in its heating current by moving the lever 13 about a pivot 14, so that when the heating current becomes sufficiently low or ceases the lever 13 disengages from the stop pin 16, and the reserve spring drive becomes effective. The bimetallic strip 20 is carried by an arm 26 connected to a post 31 by a further bimetallic strip 30 arranged to act as an ambient temperature compensator. The base 31 is rotatable by adjustment of a plate 32 to vary the lower limit of the current through the bimetallic element 20 at which the pin 16 is released by the lever 13.

Title: Improvements in or relating to fastening inserting machines
IPC: A43D69/02
Filed: 1935-01-25
Abstract: 450,968. Nailing. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation; 140, Federal Street, Boston, U.S.A.) Jan. 25, 1935, No. 2457. [Class 89 (iii)] A fastener-inserting machine having a rotatable work-support and a fastener-clenching member mounted in the support, has the member mounted for movement relatively to the support and controlling means for preventing the member from partaking in the turning movements of the support. By this arrangement, the clenching member is maintained in a fixed position in relation to the fastener-inserting instrumentalities, so that the fasteners are all clenched in the same direction. As applied to a loose-nailing machine for shoes, an anvil 24 with an elongated clenching recess 32 is rotatably mounted on a stub shaft 40 at the tip of a horn 21. The latter is fixed on a post 34 mounted for rotation and vertical movement in a fixed part 36 of the machine column. Fast with the part 36 is a gear 46 which is geared by an idler gear 48 to a gear 56 on the lower end of a shaft 58 extending up the horn 21. The gear 48, which is elongated, is held in place removably by a screw 50. A bevel gear 60 at the top of the shaft 58 meshes with a gear 62 on a shaft 42 which, at its other end, is formed with a gear 43 in mesh with a gear 41 on the anvil 24. The ratio between the number of teeth on the gears 46 and 56 is the same as that between the number of teeth on the gears 41 and 43. Then, rotational movement of the horn 21, for example, in nailing a sole 28 to the insole 27 of a shoe 26, is not transmitted to the anvil, so that the latter retains a definite position relatively to the fastener-driver, not shown, with the recess 32 parallel to the margin of the insole, so that the nails.are all clenched in a direction parallel to that margin. The recess is arranged near the edge of the anvil, so that the nails can be driven close to the insole margin, and is formed in a member 66 which is removable from the anvil for renewal. Ball bearings are provided for the anvil 24 and post 34, and a thrust bearing is arranged between the bevel gears 60, 62. Specifications 8403/10 and 265,298, [both in Class 89 (iii)], are referred to.

Class 146(3) [Also in Group VIII] In carbon papers and like manifolding sheets of the colourless type in which the sheet is coated with a colourless dye former or intermediate which is transferred by typing or printing to a copy sheet where the colour of the dye is developed by contact with acid alkaline or oxidizing components of the copy sheet, as the colour formers employed are spiro-dipyrans which develop a a high-colour intensity on contact with acids. In one method both components of the colour reaction are contained in the one sheet e.g. an acid reacting paper is coated with an emulsion consisting of 1 part by weight of an 0.3 per cent solution of spiro-di-benzopyran in chlorodiphenyl is dispersed in 5 parts of a 20 per cent gelatose solution in water. The colour is then developed by breaking the emulsion by the pressure used in writing or printing. In :the second case the spiro-dipyran is applied to a sheet of neutral material which is used in contact with a sheet of acid acting paper. In an example the first sheet is coated with a composition consisting of 5 parts montan wax, 5 parts O.P. wax, 4 parts chlordiphenyl and 2 parts spiro-di-naphthopyran while the copy sheet is made up of 70 parts hydrochloric acid treated clay, 120 parts methylcellulose 2 per cent solution 10 parts glycerine, 40 parts water and 20 parts methanol. Typewriter ribbons can similarly be saturated with solution of the spirodipyran.
