Abstract: 607,793. Electromagnets. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Dec. 12, 1945, No. 33646. [Class 35] [Also in Group XXXVII] An electromagnetic torque producer has a two-pole armature mounted for limited.rotation between two pairs of poles in such a way that the sum of the overlapping areas of pole and armature and also the air-gap are constant, whilst the width of each pole decreases away from the pole face to reduce the forces due to leakage flux, each pole pair being similarly magnetized and the torque being produced by diverting the flux to one or other of each pair of poles. As shown, the armature 15 which may operate a fluid valve or a contact arm 20, as in Fig. 1, rotates on a pivot 14 between the pole pairs 12 of the pole members 11. A permanent magnet 18 energizes the polepieces 11 and coils 25 direct to the flux produced through either of the arms 12 to pull the armature into a corresponding position. Damping may be provided by means of short-circuited coils 26 or resistance circuits 27, 28 wound on the free polepieces. At least some of the armature laminations may be shaped as in Fig. 2 to offset the effects of leakage flux.

Filed: 1966-07-28
Abstract: 1,165,183. Electrode spacers. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 28 July, 1966 [29 July, 1965; 4 March, 1966], No. 34049/66. Heading H1B. Spacers for electrodes are cut from sheet material and affixed to the electrode so that they protrude from it. The spacer material may be an insulator or conductor depending on whether the electrodes to be separated are of like or unlike polarity. It may be a thermoplastic, e.g. polypropylene or polystyrene, a thermosetting material or a porous material, e.g. paper, cardboard, asbestos or glass fibres impregnated with a thermoplastic or thermosetting material. The spacers may be punched out and affixed in a single action. A suitable apparatus is illustrated in Fig. 4. Two plates 16 and 18 separated by blocks 19 and cooled by coolant circulation 29, define a cavity 30 into which the sheet material is inserted. 21 is a resiliently mounted runway for electrode carrier 24 which is heated by coil 27. The electrode is held in the carrier by turning clips 25 upwards through 90 degrees. The carrier is then slid along to stop 26 and punches 12 lowered to punch out the spacers and contact them with the electrode. In a modified apparatus, Fig. 8, spacers may be simultaneously brought into contact with both sides of an electrode. The spacers are generally cylindrical but some may be of other than circular crosssection to deflect the electrolyte flowing between the electrodes. They may be affixed to the electrode by insertion, optionally with riveting, in holes punched out if it either before or simultaneously with the punching of the sheet. The holes may have fared edges. Alternatively, the spacers may be stuck to the electrode by fusion or by gluing with a thermosetting adhesive which may be in the form of tape which is contacted with the sheet material before punching. A second electrode may be attached to the first by affixing it to the spacers. This may be facilitated by using a second electrode which is smaller than the first and making the spacers at the edges taller than the others, as shown in Fig. 3a, to form a cradle in which the second electrode rests. The invention is disclosed as useful in a sea-water cell comprising bipolar electrodes of Mg and AgCl or CuCl 2  joined by silver foil and in fuel batteries containing cells joined in parallel and in series.

Title: Oxyalkylated phosphosulphurised hydrocarbons and lubricating compositions therefrom
IPC: C07F9/04
Filed: 1958-10-24
Abstract: Oxy-alkylated phosphosulphurized hydrocarbons, prepared by phosphosulphurizing a hydrocarbon, steam-stripping the product and then reacting it with a C2-C6 alkylene oxide (see Group IV (b)), may be used as extreme pressure or detergent additives in amounts from 0.001 to 30% by weight in mineral, animal, vegetable and synthetic lubricating oils, if desired in conjunction with the usual additives. The compounds may also be used as antioxidizing agents in cutting oils, rinsing oils, turbine oils, gear oils, transformer oils and mineral oil greases. Engine tests are described using a mineral lubricating oil containing 6% of a product obtained by phosphosulphurizing a polyisobutene (M.W. 1100), diluting with a mineral oil and steam-stripping the product and reacting it with 3-8% of ethylene oxide.ALSO:Oxy-alkylated phospho-sulphurized hydrocarbons are prepared by phospho-sulphurizing a hydrocarbon, steam-stripping the product thus obtained for a period of time sufficient to remove odours due to volatile by-product sulphur compounds and reacting the steam-stripped product with a C2-C6 alkylene oxide. The hydrocarbons, which may be paraffins, olefines, diolefines, olefine polymers, acetylenes, or aromatic, alkyl aromatic or alicyclic hydrocarbons including various petroleum fractions and cracked or condensed products therefrom, may be phospho-sulphurized with one or more phosphorus sulphides or a mixture of phosphorus and sulphur, suitably at 90-320 DEG  C., generally using 1-10 mols. of hydrocarbon per mol. of phosphorus sulphide, in an inert atmosphere.  The steam stripping is preferably effected at 100-200 DEG  C. and continued until the acid number is at least 25 and the sulphur content is below 1.5% by weight.  The steam-stripped product is preferably condensed with 1-10 mols. of alkylene oxide.  The products may be used as lubricating oil additives (see Group III) or as surface-active agents, dispersing agents and vulcanizing accelerators.  In an example, a polyisobutylene, M.W. about 1100, is reacted with P2S5, the product is diluted with mineral oil, steam-stripped at 120 DEG  C. and then reacted with 3-8% ethylene oxide using BF3/ether or NaOH as catalyst.ALSO:Oxy-alkylated phospho-sulphurized olefine polymers are prepared by phosphosulphurizing the polymer, for example with a phosphorus sulphide or a mixture of phosphorus and sulphur, steam-stripping the product for a period of time sufficient to remove odours due to volatile by-product sulphur compound and reacting the stripped product with a C2-6 alkylene oxide, for example with 1-10 mols. of the oxide.  The products are lubricating oil additives (see Group III).  In an example, a polyisobutylene (M.W. 1100) is reacted with P2S5, the product diluted with mineral oil, then steam-stripped and finally reacted with 3-8% of ethylene oxide using BF3 or NaOH as catalyst.

IPC: G08G1/09
Filed: 1965-08-10
Abstract: 1,137,137. Centre lane traffic; reversal of flow. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 10 Aug., 1966 [10 Aug., 1965], No. 34175/65. Heading G4Q. In an arrangement for reversing the direction of traffic flow in the centre lane of a roadway extending over a number of intersections, a controller is provided for modifying the operation of the intersection controllers so that access is denied progressively at all points along the lane to traffic in its current direction of use until the lane is clear and then access is given simultaneously at all points to flow in the opposite direction. As described a five-lane roadway extends between an intersection at Grosvenor St. (controlled by unit IC1) and an intersection at Plymouth Grove (IC4) over intersections at Booth St. (IC2) and Brunswick St. (IC3). Gantries G1-G8 carry traffic direction signals for the non-reversible lanes a, b (south-bound) and d, e (north-bound) and the reversible lane c assumed initially to be conveying south-bound traffic. Changeover is initiated by a signal on line DH to the controllers 101, IC2 demanding right-ofway for the main road traffic, when this is achieved the demand is removed from controller IC1 by a signal via line CRH so that this controller can terminate the main road traffic in the usual way. When this occurs control GT is effective to advance a uniselector LCU in the reversal control equipment to position 1. In this position the north-facing signal Sc on gantry G1 is turned to red and subsequently the same signal on gantries G2 and G3 are changed behind the traffic moving south along the centre lane as the uniselector switches to positions 2 and 3. In position 4 the conditions imposed on controller IC2 are removed by signal RH and the main road right-of-way at this intersection is terminated. When this occurs (signal GT) the selector steps on to position 5 in which the same conditions as affected IC1 and IC2 initially by application of signal DH are applied to controllers IC3 and IC4 and also the centre lane signal on gantry G4 is changed to red by control N.R. Subsequently the same signals on gantries G5 and G6 are changed when the selector steps on to positions 6 and 7. In position 8 the conditions imposed by signal DH on controller IC3 are removed by signal RH which imposes a termination of the main road right-of-way at this intersection. When this occurs the selector steps on to positions 9 and 10 in which respectively the centre lane signals on gantries G7 and G8 are turned to red. In position 11 the signal RH removes the conditions applied to IC4 by the signal DH and forced termination of the main road rightof-way is applied. When this is effective the signal on GT moves the selector to position 12 in which signal SG is applied to turn all the south facing centre lane gantry signals simultaneously to green.

Abstract: 1,189,984. Modifying acrylonitrile copolymer fibres. COURTAULDS Ltd. 31 July, 1967 [1 Aug., 1966], No. 34357/66. Heading B5B. [Also in Division C3] Fibres formed from a copolymer containing units derived from acrylonitrile and from an unsaturated amide having at least one hydrogen atom linked to the nitrogen atom are impregnated with an aldehyde and with a catalyst for reaction between the amide groups in the copolymer and the aldehyde, stretched before, during or after the impregnation, dried while under tension and heated to cause reaction between the amide group and the aldehyde. The copolymer may contain, copolymerized with the acrylonitrile and the amide, minor proportions of other monomers, e.g. styrene, methyl or butyl acrylate, itaconic acid, methallyl sulphonic acid and its salts, vinyl acetate, vinyl pyridine, vinyl chloride, and vinylidene chloride. The amide is preferably acrylamide, but may be an N-substituted acrylamide, such as N-methyl, N-ethyl, N-isopropyl, or N-tbutyl acrylamide, a homologue of acrylamide such as methacrylamide or an N-substituted derivative thereof. The proportion of amide in the copolymer is preferably at least 4% by weight but less than 50% by weight, particularly about 5 to 15% by weight of the copolymer. The proportion of acrylonitrile units in the copolymer should preferably be at least 50% by weight and more preferably at least 80% by weight. The aldehyde used is preferably formaldehyde (which may be obtained in situ from a formaldehyde-generating compound such as paraformaldehyde) but other aldehydes such as acetaldehyde, trichloroacetaldehyde or glyoxal may be used. Examples of catalysts which may be used are ammonium chloride, ammonium dihydrogen phosphate, hydrochloric acid, sulphuric acid, zinc nitrate, magnesium chloride, and compounds having the general formula wherein R is hydrogen or a monovalent organic radical. Examples of such compounds are maleamic acid, maleuric acid and maleanilic acid. The fibres are stretched before they are dried. The fibres are preferably treated continuously in the form of a tow by passage through a bath containing an aqueous solution of the aldehyde and the catalyst and excess solution subsequently squeezed out of the fibres. The bath is normally at ambient temperature. In an example, a copolymer formed from 87% acrylonitrile, 12% of acrylamide and 1% itaconic acid (all percentages being by weight) in a 52% aqueous solution of sodium thiocyanate is wet-spun into a 12 to 15% aqueous solution of sodium thiocyanate and the filaments thereby formed are stretched to four times their original length, washed with cold water and then passed under tension without having been first dried through a bath at 60‹ C. containing 10% by weight of formaldehyde in water. On emergence from the bath excess liquor is squeezed out of the filament and they are then dried, whilst still under tension, at 80‹ C. for 6 hours.
