Patent GB-393690-A (GB)
Title: Improvements in the manufacture and production of acetaldehyde from acetylene
Filed: 1932-01-20
Abstract: Acetaldehyde is produced by absorbing acetylene in an aqueous solution containing a neutral salt of a solid, heavy base metal having an acid reaction, the absorption being effected above atmospheric pressure at such concentration that the boiling point of the solution is at least 4 DEG  C. below that of a saturated solution while still showing an acid reaction to methyl orange. Suitable salts are the halides of zinc, chromium, iron, and cadmium, but promoters may be added such as mercury compounds (including organic compounds such as mercury diphenyl), water-soluble salts of uranium, gold, and the metals of the platinum group.  The process may also be effected by using the concentrated solutions described in the parent Specification while employing enough water vapour admixed with the acetylene to reduce the concentration of the solution to the limits defined above. The acetylene need not be as pure as is required in the process of the parent Specification.  When cadmium chloride is used, as its solubility is relatively low, a chloride of iron, zinc or chromium may be added.  If the acetylene is produced by thermal treatment of hydrocarbons such as by arc treatment or the cracking of mineral oils, other unsaturated hydrocarbons such as diacetylene and butadiene and also carbon black are removed before the absorption, which may be effected at 20 atmospheres pressure, but if the carbon black only is removed, a smaller pressure such as up to 3 atmospheres is preferred.  Or the unpurified gas may be used, when the absorption liquid is periodically purified by absorbents such as fuller's earth, bleaching earth, or active carbon.  This treatment of the solution may also be effected when partially purified gas is used.  The absorption may be effected in a cylindrical vessel containing Raschig rings or the like.  The temperature may be 80-250 DEG  C., and the gas may be preheated. Examples describe the treatment of a gas containing acetylene with zinc chloride solutions.  In one example a fifth of the solution is continuously circulated to a filter of bleaching-earth, and in another the gas is passed through a filter of ceramic material and is introduced into the solution in very finely-divided form.

Patent GB-436054-A (GB)
Title: Manufacture of stable preparations of compounds containing active halogen
Filed: 1935-01-19
Abstract: Organic compounds containing active halogen such as aryl sulphonic acid dihalogenamides, or monohalogen-amides and -imides, e.g. phthalyl halogenimides and acetyl-benzenesulphonchloramide, are stabilized by dissolving or incorporating in a nuclear chlorine substitution product of an aromatic compound, which product is not attacked by chlorine at ordinary temperature in the absence of catalysts and light.  The preferred chlorine compounds are nuclear substitution products of aromatic hydrocarbons or diphenyl ether. The final products may be liquids, pastes or ointments, and may include indifferent substances such as hexachlorethane, bolus or talc.  Chlorinated diphenyl ethers containing more than eight chlorine atoms are generally solids and are used to produce powdered products.  Examples describe the preparation of solutions and ointments containing toluene- or benzenesulphondichloramide, benzene-sulphondibromamide or chlorylphthalimide stabilized with chlorinated diphenyl ethers, monochlor- or o-dichlor-benzene, o-chlor-toluene, or a chlorinated diphenyl.  Mixtures of chlorinated diphenyl ethers with hexachlorethane or hexachlorbenzene are also employed. Dusting powders are prepared by dissolving octachlordiphenyl ether in benzene, adding toluenesulphondichloramide and evaporating to dryness, or by dissolving tetrachlorphthalic anhydride and toluene-sulphondichloramide in monochlorbenzene and evaporating.ALSO:Disinfectants consist of organic compounds containing active halogen such as aryl sulphonic acid dihalogenamides, or monohalogen-amides and -imides, e.g. phthalyl halogenimides and acetyl-benzene-sulphonchloramide, stabilized by dissolving or incorporating in a nuclear chlorine substitution product of an aromatic compound, which product is not attacked by chlorine at ordinary temperature in the absence of catalysts and light.

Patent GB-210442-A (GB)
IPC: H01H53/02
Filed: 1924-01-24
Abstract: 210,442. Regan, J. B., (Assignee of Shaver, A.). Jan. 24, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Alternating current relays, particularly for use in train control systems in which the relay is carried by the train and is momentarily energized from the track, are provided with a moving coil armature for actuating the control circuits constructed to have very small inertia, and sensitiveness is obtained by supplying the coil with current by induction to enable it to react with the fixed field system. In the arrangement shown, the light coil 10 is mounted on the aluminium spindle 12 having an adjustable cup and cone bearing in the frame surrounding the polar structure. It is supplied with current, inductively, by the flux in the fixed core 15 which threads the coil and has its winding 39 energized from an alternating- current generator 44 through a phase-controlling means consisting of an inductance 49 and a condenser 50 either of which may be placed in the circuit by manipulation of the switch 51. The fixed field is provided by the cores 33, 34 carrying a winding 35, 36 energized from a second generator 41 on the same shaft as the first and displaced thereon so to produce a phase displacement between the two supplies which ensures the coil 10 assuming a central normal position. In action, the coil moves in one direction or another according as the current in it (that is, in the winding 39) leads or lags relatively to that in the fixed field winding. The coil is biassed to the normal central position by a magnetic bar 64 on the spindle which assumes and attempts to maintain its central position between the poles 62, 63 of a horse-shoe permanent magnet 59 supported by the frame. The bar carries a projection at one end, or at both ends, to engage a spring-mounted contact 70 and force it on to a fixed contact. A number of fixed and movable contacts may be employed so that different circuits are closed in accordance with the degree of displacement of the armature. In order to damp the movement of the armature as it assumes the normal position, the shaft has mounted upon it a depending pointer 66 which, at or near the normal position, engages with a similar pointer 67 pivoted to the casing and having, at its lower end, a vane or vanes dipping into viscous liquid. During the first portion of the operative movement of the armature, the pointers pass one another and no retarding action is exerted on the subsequent movement. It is stated that the relay may be used also for, direct currents.

Filed: 1967-01-18
Abstract: 1,165,232. Bending wire. BUCHUNGSMASCHINENWERK KARL - MARX - STADT, VEB. 18 Jan., 1967, No. 2597/67. Heading B3E. [Also in Divisions B5 and G4] An inductive digital store is manufactured by superimposing two plastics foils, with aligned apertures, on a welding tool, conductor wires being inserted between the foils and guided so as to pass across the apertures, conductor loops being formed at each aperture by displacing each wire by means of a tool, after which the foils are welded together. A suitable welding device including successively-actuable grippers for displacing the wire, and locating pins, is claimed separately. A rectangular covering foil 2 of thermoplastic material having two rows of six hexagonal holes is stamped out, as is a same-sized carrier foil (1) of thermoplastic material having correspondingly-positioned but smaller circular holes. The covering foil 2 is then placed on the brass base electrode 10 (Fig. 2) of an H.F. welding tool, and conducting wire 4 laid on top around and between pins to pass diametrally across each hole and between strip-shaped springs 25 (Fig. 4) of grippers 12 protruding up through the holes. The carrier foil (1) is now placed on top, followed by a sheet of stiff paper of the same shape as the carrier foil for insulation protection against disruptive discharges. The foils and paper have extra holes, to locate them on pins 21. The rack 17 in Fig. 2 is now driven inwards so a groove 19 thereon pulls the grippers 12 in turn, downwards against springs 16 by means of pins 20. As each gripper 12 descends, a leaf spring 27 (Fig. 4) bearing on a sleeve 28 in the base electrode 10 pushes studs 26 into holes in the springs 25 of the gripper to cause them to grip the wire 4 to pull it down into a loop. The brass cover electrode 31 (Fig. 1) with raised portions 34 is now pressed down in position, pins 32 engaging bores 33 and application of H.F. voltage between the electrodes 10, 31 welds the foils together around the wire 4 and around the edges. The read-only store is completed by severing the wire 4, which is clamped at 23, and inserting magnetic cores into the holes in the double-foil, the wire loops being placed on one side or the other of the cores depending on the information to be stored.
