Abstract: 675,295. Writing-telegraphs. AUTOMATIC TOTALISATORS, Ltd., May 5, 1949. [March 25, 1949] No. 12074/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1949]. Class 40 (i). [Also in Group XV] The movement of the transmitter arm of a facsimile recorder is analysed into rectangular components of voltage by mechanical connections to the sliding contacts of two potentiometers, which are transmitted through two separate channels to the receiver where perpendicularly acting solenoids are energised in accordance with the components and reproduce the movement in a pen recorder. The transmitting pen (Fig. 1) is maintained at one end 25 of an arm 20 attached to the slider 19 of a potentiometer 21, and which is pivoted at 22 to another arm 15 attached to the slider 13 of a potentiometer 11, so that movements at 25 vary the voltages taken from the potentiometers. A pen recorder 57 at the receiver (Fig. 2) is attached to an arm 55 which is subjected to movement in two perpendicular directions by the actions of armature 75 of solenoid 77, fed from potentiometer 11 of the transmitter, and armatures 85 of solenoids 83 fed from potentiometer 21. The action of writing at the transmitter closes contacts 33 under the writing table, and energises a relay 95 at the receiver which allows the pen 57 to be lowered on to a writing surface, and subsequently repeat the shapes drawn by the transmitting pen. After each line of writing, a paper feed roll 35 is advanced manually, thereby rotating a ratchet wheel 43, causing switch contacts 45 to make and break the circuit of a relay 97, thereby rotating a ratchet 101 and feeding a paper roll 99 at the receiver by a similar amount.

Title: Process for the preparation of artificial silk, artificial spun fibres, horsehair, bands, films and the like from soya bean casein
IPC: D01F4/00
Filed: 1937-11-26
Abstract: 508,840. Artificial silk &c. POTTER, E. (Akt.-Ges. f³r Vermogensverwertung) Nov. 26, 1937, No. 12256 /39. Divided out of 508,781. [Class 2 (ii)] Artificial silk, spun fibres, and horsehair, and also bands, films and the like, are prepared from solutions of soya bean casein to which have been added carboxylic acids having at least 3 carbon atoms or their derivatives such as their esters or amides, with or without aliphatic amines or amino acids. Propionic, heptylic, n-caprylic, n-capronic and stearic acids are specifically mentioned as acids, and n-propylamine, allylamine, or n-butylamine as amines. A small quantity of carbon disulphide in the proportion of 2 to 5 per cent by weight of the casein may be added. Numerous other additions and after-treatments are referred to. Thus vinyl acetate, polyvinyl chloride, polyvinyl alcohol, titanium dioxide, butadiene, olefines, sulphonated olefinic alcohols, aldehydes, phthalic , anhydride and glycerine, formaldehyde and urea, phenols, and other substances which form condensation products with one another or with the casein may be added to the casein solution, or, in the case of dry spinning, may be passed as vapours in counter current to the thread or film. Acid vapours, for example of hydrochloric acid, may be similarly employed in dry spinning. The threads &c. may be hardened by formaldehyde or synthetic or natural tanning agents, or by subjecting them to the action of light from a mercury vapour lamp, and their capacity for dyeing may be increased by treatment with amines or amino acids. In an example, soya bean casein is made into a viscous solution with sulphuric acid and glycerine, and propionic and stearic acid added. The solution is spun into a precipitating bath of water or a sodium sulphate solution and the spun products dried under tension and hardened by formalin. In another example an alkaline solution of soya bean casein with carbon disulphide, npropylamine, and propionic acid is spun into a precipitating bath of sulphuric acid, the product dried under tension and hardened in formalin.

Patent GB-693757-A (GB)
Title: Manufacture of an intermediate product and of azo dyestuffs derived therefrom
IPC: C09B45/14
Filed: 1950-05-17
Abstract: The invention comprises g -(4-hydroxy-1-naphthyl)-butyric acid, which can be prepared by (1) reacting a -naphthol with a derivative of succinic acid, e.g. anhydride or chloride, or (2) dealkylating an alkyl ether thereof (especially methyl or ethyl) with aqueous alkali hydroxide at 100 DEG  C. or higher, e.g. 130-160 DEG  C.  The alkyl ethers are made by condensing ethers of a -naphthol with succinic anhydride in the presence of aluminium chloride.  In the examples: (1) a -naphthol is heated with succinic anhydride and aluminium chloride in tetrachlorethane; (2) g -(4-methoxy-1-naphthyl)-butyric acid is heated to 140-145 DEG  C. with aqueous sodium hydroxide.  The product is a coupling component for azo dyes (see Group IV (c)).ALSO:Azo dyes are made by coupling a diazotized o - hydroxyamine with g  - (4 - hydroxy - 1-naphthyl)-butyric acid, followed if desired by metallization in substance, in the dyebath or on the fibre.  The diazo components may contain a benzene, naphthalene, anthraquinone or heterocyclic nucleus.  The metal-free dyestuffs are suitable for dyeing and printing fibres of wool, silk, casein, superpolyamides and animalized cellulose.  Those not containing sulphonic acid groups may be applied to wool by the metachrome process, or the wool dyeings may be after-treated with agents providing copper, chromium or cobalt.  Difficultly soluble copper, chromium and cobalt compounds produced in substance may be used as pigments.  In the examples, dyestuffs are made from the following diazo components: 5-nitro-2-aminophenol, 5 - nitro - 3 - aminosalicylic acid, 6 - nitro - 2-aminophenol - 4 - sulphonic acid, 2 - aminophenol - 4 - sulphonamide and 2 - aminophenol-4 : 6-disulphonic acid (coppered).  In further examples: (1) wool is dyed blue by the metachrome process using the dyestuff from 5-nitro-4-chloro-2-aminophenol; (2) wool is dyed red by using the dyestuff from 2-aminophenol - 4 - sulphonamide and coppering in the dyebath; (3) wool is dyed violet-brown by the metachrome process with the dyestuff from 5-nitro - 2 - aminophenol.  4 - Nitro - 2 - aminophenol is also specified as a diazo component.
