Title: Improvements in the preparation of sisal fibre
IPC: D01C1/02
Filed: 1942-01-26
Abstract: 555,606. Treating sisal fibre. NANJI, D.R., and SISAL GROWERS ASSOCIATION. Jan. 26, 1942, No. 1083. [Class 2 (ii)] Sisal fibre is prepared for textile operations by decorticating it and then treating it at ordinary room temperature in a bath of dilute caustic alkali solution containing a calcium compound and if desired also sodium aluminate, or zincate, in order to remove silicic acid compounds from the fibre without removing non- cellulosic gums. The alkaline treatment may be effected with a 1-4 per cent. solution of caustic soda containing a mixture of calcium hydrate and sodium zincate or aluminate, which mixture may be present to the extent of 0.05 per cent. or more. The treatment renders the fibres soft and pliable. After removing the alkali by washing, the fibre may be steeped in a solution of spindle oil. The dried and brushed product may be hackled, and the fibres then spun to fine count yarn. The fibres are absorbent and dye readily. They may be sized and may be formed into polished twines and lines. Specifications 14149/02, [Class 120], 274,331, 339,850, [both in Class 2 (ii)], 457,171, 458,310 and 529,808 are referred to.

Title: Manufacture of resinous or cuprene-like condensation and polymerisation products of acetylene
IPC: C07C2/00
Filed: 1925-01-17
Abstract: Condensation and polymerization products of acetylene are produced by reacting with acetylene upon an organic substance (other than a phenolic body) in the presence of a catalyst at substantially atmospheric pressure, the reaction mixture being maintained at a raised temperature for a sufficient time to produce resinous or cuprene-like substances as the main product of the reaction. Examples of the organic substances employed are aliphatic and aromatic hydrocarbons such as methane, hexane, liquid and solid aliphatic hydrocarbons, benzene, xylene, p  naphthalene and hexalin; also alcohols, glycols, chlorides, carboxylic acids, oxycarboxylic acids, halogenated carboxylic acids, and their esters.  The salts of mercury and aluminium are applicable as catalysts, whilst activators, such as acids and alkalies, may also be present.  According to the reaction conditions, the products will be of the cuprene or of the aldehyde resin type; when of the latter type they may be improved by known processes.  According to the examples, (1) acetylene is introduced into an emulsion of mercury benzene sulphonate in glacial acetic acid; when absorption is complete, the mixture is heated and then leached with water to obtain a resinous substance; (2) into a heated emulsion of amyl alcohol and mercury sulphate, acetylene is passed until the absorption nearly ceases; the product, after decantation, can be used directly as a lacquer, or the resin present may be isolated by distilling off the amyl alcohol; (3) a cuprene-like substance is obtained by introducing acetylene into a heated emulsion of aluminium chloride in dry benzene, mixing the product with water and steam-distilling away the benzene; (4) acetylene is passed into a heated mixture of hexane and mercury sulphate and the product heated for some hours; on distilling off the hexane, a solid resin remains; (5) mercury sulphate is emulsified with chlorbenzene and acetylene introduced into the heated mixture; the viscous mass is mixed with water and the volatile components distilled off with steam.  The Specification as open to inspection under Sect. 91 (3) (a) includes the manufacture of resinous products from phenols.  In an example mercury acetate is dissolved in hot phenol, concentrated sulphuric acid added and then acetylene passed in; when the mixture becomes viscous, a semi-solid resin can be obtained by leaching with hot water; further heating before leaching yields a solid resin.  This subject-matter does not appear in the Specification as accepted.

[Also in Division H1] A semi-conductive circuit arrangement comprises a body exhibiting high field instability (e.g. Gunn) effects, having decreasing crosssection resistance from one end to the other, and which is biased by means including an input signal, to a level less than the instability threshold value, so that on the application of a trigger pulse, a high field domain is created which propagates along the body distance dependent on the level of the input signal; the. domain ceases where the lower resistance reduces the field below that necessary to sustain the domain As the domain propagates along the body a series of output pulses representative of the input signal are provided by means such as that shown in Fig. 6 comprising grooves 4 cut into the body 1, each reduced cross-section providing a current pulse as it is traversed by the domain. The reducing resistance is provided in Fig. 6 by making the body 1 wedge shaped. In an alternative arrangement, the periodic changes in resistance are provided by changes in doping instead of grooves; in a further embodiment (Fig. 8) the pulses are obtained from a sequence of electrodes 15 insulated from the body by a a silica layer 22. Instead of a wedge shape, the body may be shaped to provide a logarithmic or other law. The semi-conductor may consist of Ga As or InP and the electrodes of tin. The device may be used as a solid state coder to provide analogue to digital conversion.
