Abstract: 776,948. Socket for wire rope. PRIESTMAN BROS., Ltd. Nov. 25, 1955 [Dec. 6, 1954], No. 35278/54. Class 109. A socket 1 for attachment to the end of a wire rope 6, has a bore, part of which is conical, and part of which is provided with an internal sleeve 12 of resilient material, preferably rubber, which embraces the rope. Preferably, the diameter of the part of the bore containing the sleeve 12 is greater than the minimum diameter of the conical part, and one end 13 of the sleeve 12 is formed with a flange which is turned over to embrace the end 5 of the socket to protect the socket from contact with the rope and with external objects and also to prevent damage to the cable inside the socket by moisture. The sleeve 12 may be longitudinally split and sealed to the socket by a petroleum-rubber adhesive.

Patent GB-762159-A (GB)
Title: Production of terpolymers
IPC: C08F220/44
Filed: 1954-12-07
Abstract: Clear terpolymers of (a) a -methylstyrene, (b) acrylonitrile, and (c) methacrylonitrile or an alkyl methacrylate are prepared by a free-radical initiated batch polymerization, to at least 20 per cent conversion of a monomer mixture selected from the area that gives clear terpolymers lying on or about (i.e. within 5 per cent of) the line joining the polymerization azeotrope compositions of (a) and (b) and of (a) and (c) as plotted on an equilateral triangular co-ordinate graph.  The azeotrope compositions give interpolymers containing the same relative proportions as the initial monomer mixtures.  The alkyl group in (c) may be methyl, ethyl, n- and iso-propyl, n-sec.- and tert.-butyl.  In examples, mixtures of a -methyl styrene, acrylonitrile and methacrylonitrile or methyl methacrylate are polymerized by heating in three stages. Graphs are given.  The polymerization may be carried out in mass, in suspension in water using suspending agents such as tricalcium phosphate and carboxymethylcellulose (which may yield pearls), or in emulsion using a redox-catalyst and an emulsifying agent such as a salt of a sulphonated long-chain alkyl aromatic compound or a condensation product of ethylene oxide and a long-chain aliphatic alcohol or mercaptan.  The term batch polymerization includes the addition of the monomers in fixed proportions to a continuous system, e.g. a series of vessels.  Catalysts mentioned are hydrogen, benzoyl, di-t.-butyl, and diacetyl peroxides; t.-butyl and cumene hydroperoxides; diethyl peroxycarbonate, potassium persulphate and perborate; a ,a 1-azodiisobutyronitrile, p-bromobenzenediazonium fluorborate, N-nitrosop - bromoacetanilide, azomethane, phenyldiazonium halides, diazoaminobenzene, p - bromobenzenediazonium hydroxide and p-tolyldiazoaminobenzene. Heat alone or ultraviolet light, if desired in the presence of a photosensitizer such as an organic disulphide, may also be used.

Patent GB-789263-A (GB)
Title: Improvements relating to the dyeing of polyacrylonitrile fibres and films
IPC: C09B44/02
Filed: 1955-12-14
Abstract: Textiles and films of polymers or copolymers of acrylonitrile are dyed or printed by applying an azo dyestuff free from acid solubilizing groups but containing a cyclammonium group (a hetero ring containing a tertiary nitrogen atom which is quaternized) or a salt of such a dyestuff with an acid.  Dyeing may be effected from a weakly alkaline, neutral or weakly acid bath at the boil or under pressure.  The cyclammonium group may form an external substituent as described in Specification 295,032, [Class 2 (iii)], but preferably the nitrogen atom forms a resonance system with the arylazo group. Alternatively, the arylazo group may be bound to the cyclammonium group by means of a p-phenylene radical, as in the 2-(p-arylazophenyl)-N-alkyl benzthiazolium salts, or it may be bound directly to a carbon atom in the cyclammonium ring, which carbon atom is in a neighbouring position to the nitrogen atom.  The cyclammonium group may be derived from 5- or 6-membered rings, if desired containing, in addition to the nitrogen atom, other hetero atoms, e.g. pyridine, pyrazole, imidazole, triazole, tetrazole, oxazole, thiazole, selenazole, oxdiazole, thiadiazole, pyrimidine, triazine, quinoline, indazole, benzimidazole, naphthimidazole, benzoxazole, naphthoxazole, benzthiazole, naphthothiazole or benzoselenazole rings.  Numerous dyestuffs and examples of dyeing are given.

[Also in Group XXXVII] A pawl-and-ratchet mechanism for driving rotary electric switches (Figs. 1, 2, not shown) step-by-step upon successive energizations of a rotary solenoid having limited angular movement and which may be constructed as disclosed in Specification 602,812, [Group XXXVII], is provided with means to prevent overshooting of the ratchet-wheel each time it is advanced one step by the pawl. Energization of the solenoid (Fig. 4, not shown) causes counter-clockwise movement of a shaft 12 carrying a drive yoke 22, a slot 24 in the yoke receiving a downwardly-extending finger 73 of a plate 57 mounted for sliding movement in the direction of its length, whereby the plate moves to the position shown in Fig. 5. The plate 57 pivotally carries on a pin 61 a two-armed pawl 64 having a tooth 65 for driving the ratchet-wheel 54 and a tooth 66 serving as a detent by engaging the side of the ratchet teeth. On de-energization of the solenoid the tooth 65 slips over the wheel and the detent 66 moves away from the wheel under the action of a restoring spring (not shown). Energization of the solenoid causes the tooth 65 to advance the wheel 54 one step, the detent 66 preventing rotation of the wheel beyond this amount. A spring 68 biases the pawl against the ratchet wheel and the latter is mounted on a stub-shaft 50 driving the electric switches.
