Abstract: 162,246. Morgan Crucible Co., Ltd., and Speirs, C. W. Oct. 7,1919. Resistance furnaces.-Resistance tubes or crucibles are separated from a refractory outer wall by natural graphite in the form of flakes, which may be got by grinding the graphite and freeing it from dust; graphite of high carbon content should be used. Such flaky graphite, if loosely packed, has low electric and thermal conductivity and is sufficiently elastic to allow expansion and contraction of the crucible &c. Around the cooler part of the crucible, from the bottom terminal to a point within the casing, there may be placed a fine powder, such as sand or finely-ground earthenware, to insulate the graphite from the terminal.

Abstract: 1,137,413. Arc rupturing in switches; discharge tubes. ALLMANNA SVENSKA ELEKTRISKA A.B. 14 April, 1966 [15 April. 1965; 24 May, 1965], No. 16333/66. Headings H1D and H1N. To interrupt an A.C. or D.C. circuit without excessive arcing, a gas discharge valve is connected in series with a circuit-breaker or isolating switch and is provided with means to change at least one of its parameters so that the discharge in the valve changes from a plasma condition with a low arc voltage drop to a space charge condition with a high voltage drop. When it is desired to open the circuit, a switch in parallel with the valve is first opened so that the current is shunted through the valve and reduced by the valve before the series circuitbreaker or isolator is opened. The nature of the discharge in the valve may be changed by reducing the strength of a magnetic field, Fig. 2 (not shown), reducing the effective diameter of the valve using iris type diaphragms 11, Fig. 3, in the valve, or by admitting a small quantity of gas to the valve to initiate the lowvoltage arc-discharge and then evacuating the valve to change the discharge to its high voltage condition, Figs. 4 and 5 (not shown).

Abstract: 754,035. Automatic control systems for straightening webs. WEBER & CO., Inc., H. G. June 4, 1954, No. 16610/54. Class 38 (4). [Also in Group XVI] The side-ways deviations of a travelling web are sensed by a pneumatic device which controls an aligning mechanism at intervals determined by a footage control device so that the result of correction is evaluated before further correction occurs. The edge of a moving web 12, Fig. 2, is positioned over an aperture 55, Fig. 4, or apertures 28, 29, Fig. 3, in a tube 25 connected to a source of gas under pressure, so that the sideways variation of the position of the web is detected by the pressure in tube 25. Air under slight pressure is fed to tube 25 over pressurereducing valves 36, 37 and bleeder valve 41, and the pressure actuates one or other of switches 50, 51 according as the web moves to one side or other; in the central, or correct position, neither switch is closed. Switches 50, 51 close circuits to actuate motor 67, Fig. 1, in the appropriate direction and thus shift roll 11 laterally; motor 67 is operated for a predetermined time at pre-determined intervals. Motor control system.-A footage control switch 65, Figs. 2, 5, is actuated periodically in accordance with the length of web passing and momentarily short-circuits condenser 115 to discharge it quickly over resistance 143; valve 90 thereupon conducts upon the positive halfcycles of the supply voltage 92, 93 to actuate relay 102; during the negative half-cycles condenser 115 is charged over lines 109, 110, 111, condenser 115, resistances 117, 118, rectifier 119 and resistance 104, line 103, switch 98; the charge on condenser 115 is thus incrementally increased until it inhibits current through valve 100 and relay 102 is de-energized. Switch 98 is closed whenever motor 17, Fig. 2, is driving roll 16. Relay 102 thus closes contact 125 for a predetermined time at intervals determined by the setting of switch 65, and relays 150, 151 are actuated to close contacts 161, 162 to complete a circuit to determine the direction of energization of motor 67 in accordance with the actuation of switches 50, 51. As shown, switch 50 is closed, and a circuit is completed over switch 50, contacts 161, selector switch 175, relay 189, which actuates to operate contacts 203, 204 and drive motor 67 in one direction. If switch 51 were closed, relay 225 would be actuated to drive the motor in the reverse direction. If neither switch 50, 51 is actuated, the motor is not driven. In Fig. 6, not shown, a circuit is disclosed in which five webs from eight unwind reels are aligned. A single footage control switch and timing circuit is used, but each web has its own lateral detector controlling its own motor over a selective circuit.

Title: Improvements in or relating to ion exchange membranes
IPC: C08J5/22
Filed: 1957-06-17
Abstract: Ion-exchange membranes are made from a plurality of polymeric materials containing ionexchange groups by a process comprising contacting solid polymeric material which is inert, i.e. substantially unreactive in respect of ionexchange capacity and substantially waterinsoluble, with an ethylenically unsaturated liquid monomeric material and then polymerizing the monomeric material.  Suitable inert polymers are rubber, polyamides, urea and phenolic resins, and polymers of ethylene, propylene, vinyl and vinylidene halides, acrylonitrile, alkyl acrylates and methacrylates, vinyl ethers and butadiene, e.g. a butadiene-acrylonitrile rubbery copolymer.  Suitable ethylenic monomers are styrene, methyl styrene, alpha-chloro- and -bromo-styrenes, halogenated styrene, chloromethyl and bromoethyl styrenes, esters of styrene sulphonic acid, vinyl pyridine, piperidine, lutidine, carbazole, sulphones, naphthalene and aniline, acrylic and methacrylic acids, allylamine and dimethylaminoethyl and diethylaminoethyl acrylates and methacrylates; these monomers may be used in admixture with one another or with crosslinking monomers such as divinyl benzene, ethylene dimethacrylate, diallyl carbonate and phthalate and triallyl cyanurate.  Polymerization is preferably carried out by exposing the preformed polymeric material, either before or after contacting with the ethylenic monomer, to a source of high energy radiation such as ultraviolet and X-rays, pile radiation and alpha, beta and gamma rays, the ethylenic monomer being, at least in part, graft polymerized on to the preformed polymer.  Where the ethylenic monomer is ionizable, the resulting material may be used directly as an ion-exchange material, although in the case of vinyl pyridine the ion-exchange effect may be enhanced by quaternization with t-butyl bromide; but when the ethylenic monomer contains no ionic groups, these are introduced by after-treatment, e.g. in the case of styrene it may be treated with chlorsulphonic acid, oleum or sulphuric acid to introduce acidic groups or it may be chlormethylated and the resulting chlormethyl groups reacted with a tertiary amine, e.g. trimethylamine, to introduce basic groups.
