IPC: H01H35/14
Filed: 1960-04-22
Abstract: 976,188. Inertia switches. ENGLISH ELECTRIC CO. Ltd. April 17, 1961 [April 22, 1960], No. 14144/60. Heading H2B. A switch has a multiplicity of independent peripherally arranged (Fig. 4, not shown) contact sets 64, 68 simultaneously released into engagement by an acceleration-responsive trigger. Under acceleration forces a mass 2 moves against a spiral spring 4 and under the control of a governor 8 to drive a roller 21 on a latch 17 on fixed pivot 18 out of its path until it releases a second roller 23, thus permitting its spindle 74 to move forward under a spring 75 to move contacts 68 into engagement with 64. The switch may also be manually operated by a detachable handle (not shown) used to rotate a shaft 31, carrying a gear 30, anticlockwise thus driving a rack 29 and a spiral worm 26 rigid therewith to the left; this initially rotates a gear 40 to wind the spring 4 which it carries and thereafter, when levers 41, 45 engaging the end of worm 26 permit a biased rack 39 to rise, causes gear 40 to roll on rack 39 driving the mass 2 to the left until latch 17 is released as before. Reverse rotation of gear 30 draws the mass 2 and the roller 23 to the right until the latter is relatched by latch 17 under the influence of a spring urged cam surface 22. The worm 26 is also employed to adjust the tension of spring 4: by releasing a nut 28 the worm can be rotated independently of the rack 29 thus winding the spring through gear 40.

Patent GB-832823-A (GB)
Title: New thermoplastic moulding compositions
Inventor: FENDLEY JOHN ATTON
IPC: C08L9/00
Filed: 1957-05-08
Abstract: Thermoplastic moulding compositions comprise 25 to 90% by weight of a non-rubbery copolymer prepared by copolymerizing mixtures containing 50 to 85% of styrene and 15 to 50% of at least one compound selected from acrylonitrile, methacrylonitrile and fumaronitrile, and 75 to 10% of a copolymer of butadiene-1,3 and methacrylonitrile, optionally with a small amount of a copolymerizable cross-linking agent, e.g. divinyl benzene or glycol dimethacrylate.  The polymers may be prepared by polymerizing in aqueous emulsion in the presence of emulsifying agents, e.g. sodium lauryl sulphate, sodium oleyl sulphate, sodium cetyl sulphate, the sodium salts of sulphonated castor oil or sulphonated or sulphated methyl oleate, sodium oleate, sodium palmitate, sodium stearate, and hydrogenated and dehydrogenated rosin acid soaps, catalysts, e.g. hydrogen peroxide, potassium persulphate and redox systems such as cumene hydroperoxide or benzoyl peroxide with a heavy metal salt and, if desired, sorbose or fructose, modifiers, e.g. di-(sec.-butyl) disulphide, di-(2-methylbutyl) disulphide, dialkyl xanthogen disulphides, di-orthodinitrophenyl disulphide and dodecyl mercaptans, and freezing point depressants, e.g. methanol.  The rubbery copolymer preferably has a high gell content, e.g. at least 70% insoluble in methyl ethyl ketone after extraction for 24 hours at 20 DEG  C.  The gell content may be increased by polymerizing to at least 85% conversion or by masticating on a heated two-roll mill.  The copolymers may be blended by mixing dispersions and coagulating or spray drying, by adding one copolymer in dry powder form to a dispersion of the other and removing the water, or masticating the copolymers in dry form. Pigments, e.g. carbon black, fillers, lubricants, e.g. calcium stearate, and antioxidants, e.g. phenyl-b -naphthylamine, alkylated and styrenated diphenylamines, the condensation product of diphenylamine and acetone, di-tert.-butyl paracresol and di-orthotolylethylenediamine, may be incorporated and the compositions moulded to form pipes, pipe couplings, refrigerator parts, kick panels, protective helmets, wheels, gears, pulleys and combs.
Patent GB-421154-A (GB)
Title: Process for the production of salts by means of base-exchanging substances
IPC: B01J39/00
Filed: 1934-05-15
Abstract: In the production of salts by the use of base-exchanging substances, a solution of a salt containing the same cation as the salt which it is desired to produce, water, a solution of a salt containing the same anion as the salt which it is desired to produce, and water are passed in immediate succession through the base-exchanging substance, this process being repeated continuously and the base-exchanging substance being always covered with liquid, so that it is at no time exposed to air. Preferably also, the water and the salt solutions, before use, are freed from air, as by placing them under a vacuum. In carrying out the process the base-exchanging substance may be supported in a comparatively thick layer on a perforated plate within a tower. In the production of sodium nitrate, for example, a sodium base-exchanging body may be initially covered with water, and calcium nitrate solution, water, sodium chloride solution, water, and so on be successively supplied above the upper surface of the base-exchanging body, but below the upper surface of the liquid, the rate of withdrawal of liquid from the base of the tower being adjusted to keep the liquid level constant.  The layer of sodium nitrate solution obtained, together with portions of the preceding and succeeding water layers, is collected and evaporated to yield sodium nitrate, whilst the layer of calcium chloride solution obtained, together with portions of the preceding and succeeding water layers, may be worked up to solid calcium chloride.  Two or more towers may be used for the process, in which case only the middle part of the layer of nitrate solution obtained from a tower may be collected and worked up, the outer parts of the layer being supplied to another tower before and after a concentrated calcium nitrate solution.  Alternatively, the first and most thoroughly converted part only of the layer of nitrate solution from one tower may be collected, the remainder being conducted over freshly regenerated base-exchanger in another tower prior to the supply of a concentrated calcium nitrate solution.  In order to minimize solution of the base-exchanging body during the course of the process, the water and/or the salt solutions used may carry a small quantity of silicate.  Sea water, enriched if desired with sodium chloride, may be used as the source of sodium chloride when producing sodium nitrate.  Specifications 407,311 and 407,313 are referred to.
Patent GB-774402-A (GB)
Title: Improvements in and relating to circuit arrangements for power factor regulating systems
IPC: H02J3/18
Filed: 1954-05-19
Abstract: 774,402. Automatic power factor control systems. STERN, W. L. Aug. 12, 1955 [May 19, 1954], No. 14671/54. Class 38 (4). In a power factor regulating system, of the type in which a regulating switch responsive to power factor controls the connection of capacitors with the regulated circuit, economy is effected by the successive connection by the switch contacts of all the possible parallel combinations of a comparatively small number of capacitors to provide a relatively large number of regulating steps. Thus the rotation of a mercury switch RS, as described in Specification 537,874; in response to the power factor to be controlled, results in the effective successive making of contacts 1-7 with a return contact O, whereby coils controlling mercury contactors A, B, C for the condensers (not shown) are energized from supply terminals S1, S2. Contacts 1, 3, 5, 7 control the energization of contactor A and hence the switching of a capacitor of, say, 10 units. The contacts 2, 4, G control the energization of relays W1, W2, W3 respectively which through their contacts 2M, 4M, 4B<SP>1</SP>, 6M control the energization and de-energization of contactors B, C and hence the switching of capacitors of say 20 and 40 units. Relays W1-W3 also control the de-energization of contactor A and disconnection of the 10 unit capacitor through their respective contacts 2B, 4B, 6B. Thus the rotation of switch RS results in the successive connection of all possible parallel combinations of the 10, 20 and 40 unit capacitors to provide seven regulating steps corresponding to the seven switch contacts. The mercury switch may be replaced by a motor whose-angular position results in the actuation of capacitor-controlling switches in response to the power factor.
