Title: Process and reactor for the oxidation of olefins
IPC: B01J23/50
Filed: 1952-09-29
Abstract: Olefines are converted to their oxides by passing a gaseous mixture of the olefine and molecular oxygen in contact with catalyst particles consisting of an inert support coated with active silver, the particles being disposed in the reaction zone with increasing activity from the initial contact of the mixture with the catalyst to the discharge of the products from the catalyst.  The particles may be arranged in a plurality of zones in the reactor.  Catalysts mentioned comprise silver or mixtures of silver and silver oxide supported on fused alumina, magnesia, zirconia, corundum or mullite. Preferably the catalyst is in the form of spheres having roughened or indented surfaces.  The spheres are generally about 3/8 th of an inch in diameter. Silver is deposited on the spheres from a slurry of sodium hydroxide and silver nitrate, the product being roasted at 400 DEG  C. The catalyst may be promoted with salts or oxides of metals such as Ba, Ca, Sr and Li.  Activity changes may be accomplished by changes in the concentration of silver, varying the promoter concentration or by using catalysts prepared by different methods in different sections of the chamber.  Diagrams of suitable arrangements of catalysts are provided.  In an example ethylene and oxygen at 258-276 DEG  C. and 140 p.s.i.g. are passed over a catalyst increasing in activity in zones in the direction of flow and comprising silver on mullite promoted with barium oxide and results obtained in the production of ethylene oxide compared with runs in which the reactants are passed over a fully active catalyst only. Propylene may also be oxidized.ALSO:Catalysts used in the production of olefine oxides by the oxidation of olefines comprise silver or mixtures of silver and silver oxide supported on fired alumina, magnesia, zirconia, corundum or mullite.

Title: Improvements in or relating to apparatus for operating electric motor controllers
IPC: H01H33/30
Filed: 1931-08-31
Abstract: 387,408. Actuating controllers. GENERAL ELECTRIC CO., Ltd., Magnet. House, Kingsway, London, and LINDLEY, A. L. G., Fraser & Chalmers Engineering Works, Erith, Kent. Aug. 31, 1931, No. 24456. [Class 38 (iii).] A controller, for example, a liquid rheostat for starting an alternating-current colliery winding motor, is actuated by a fluid-operated piston 9 moving in a cylinder 8, and the forward movement causes a plunger 24 to discharge fluid from a separate cylinder 25 through a valve 26 which may be adjusted whilst the apparatus is operative. Upon movement of a hand-lever 5 in a clockwise direction, a lever 31 is rotated anti-clockwise by an arm 34, about a pivot by which it is connected to a cross-arm 21, so that a link 32 is moved to operate a valve 15, and admit compressed air below the piston 9. As the piston rises to operate the controller, the cross-arm 21 is rotated anticlockwise, and the valve 15 is closed when the controller has followed the movement of the lever 5. The valve 15 may remain open to a small extent to maintain the pressure. The upward movement of the piston causes downward movement of the plunger 24 which is coupled with the crossarm 21 so that oil is forced out of the cylinder 25 through the valve 26, and through a pipe 28 into the oil-filled casing containing the gear, and on to guides 11 in which slide a crosshead 10 attached to the piston 9. The valve 26 is adjusted by means of a handwheel 27. A comparitively large non-return valve 30 is provided in the cylinder 25, through which oil is easily drawn when the controller is returned to its " off " position. The valve 15 may be adjusted by the movement of the piston 9, or by a torque-motor energized in accordance with the main motor current. The initial movement of the controller may be free by providing a port in the cylinder 25 which is covered by the piston 24 during the latter part of its stroke.

Abstract: 426,711. Coal - cutting machines. BRITISH JEFFREY - DIAMOND, Ltd., Stennard Works, Wakefield, Yorkshire, and JEFFREY, R. K., 8, Sessions Village, Bexley, Columbus, Ohio, U.S.A. Sept. 4, 1933, No. 24511. [Class 68 (i)] [See also Group XXV] Chains of the stiff-back type for coal-cutting machines comprise inner and outer links 22, 23, Fig. 1, the outer links having parts 31 extending in both directions beyond the pivotal link connections and adapted to engage the upper edges 30 of the inner links. The parts 31 of successive outer links may also mutually abut and they are preferably formed as extensions of the web of U-shaped or straddle type links. Laterally extending ribs or projections may be formed on the links for engaging guides in the jibs in which the chain is intended to work, and clamps 26 may be provided on either the inner or outer links for any suitable type of cutter. Various forms of joint-pin connections are described. As shown in Fig. 5, the pin 39 has pairs of lugs 40 at each end adapted to pass through similarly shaped apertures in the links when brought into register. In the normal working positions of the links, the apertures are out of register and the pins locked to the outer links by the lugs. Another form of joint pin is shown in Fig. 8 comprising two cylindrical parts 41, 43 which are eccentrically disposed to each other. Rotation of the pin relatively to the outer links is prevented by the cylindrical part 43. In Fig. 9 the pins have flattened ends 51 and the outer links have key-hole apertures. The parts are locked in working position by headed pins 53 carried by the inner links. As shown in Fig. 12, cylindrical joint pins 57 are employed and are locked to the outer links by transverse pins passing through the joint-pins and having heads engaging countersunk recesses in the sides of the links. In order to provide a sufficient bearing when the chain is rounding the ends of the jib, the bearing edges of the links may be concaved.

Title: Cellulosic web
IPC: D21H17/19
Filed: 1960-07-15
Abstract: A web is composed of waterlaid papermaking cellulose fibres uniformly carrying on at least the surface of the fibres between 25% and 300% based on the weight of the fibres and preferably 50%-150%, of polymerized methyl methacrylate directly connected to the cellulose by a carbon-to-carbon linkage.  The web may include up to about 15% by weight of the methyl methacrylate present of a reacted content of other polymers, such as acrylonitrile methyl and ethyl acrylate, vinyl chloride and vinylidene chloride units. According to an example, a stock emulsion, prepared by emulsifying 6,5 parts by weight of monomeric methyl methacrylate in 100 parts of water containing 0,05% by weight of dimethyloctadecyl benzyl ammonium chloride and purged of air by nitrogen, was run into a closed treating vessel containing paper supported on a stainless steel rod, the amount of emulsion containing several times the weight of methyl methacrylate to be reacted.  Ceric ammonium sulphate catalyst solution was run in with gentle agitation in such amount as to make the emulsion 0,005 molar in ceric ion, the pH was reduced below 2 by addition of nitric acid, and the contents of the vessel were gently agitated.  Reaction times of 10, 15, 30 and 70 minutes employed in four experiments yielded paper containing 56, 100, 193 and 280% of its weight of methyl methacrylate.  Other catalysts mentioned are ceric ammonium nitrate and cobaltic sulphate.  Specification 886,552 is referred to.

Title: A system for detecting the orientation of a flat article with respect to a feature provided thereon
IPC: B07C3/14
Filed: 1965-06-11
Abstract: 1,107,771. Detecting orientation photoelectrically. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. June 11, 1965 [June 18, 1964], No. 24775/65. Heading G1A. The orientation of flat articles such as cheques is determined by providing them with different numbers of marks (e. g. one and two) near opposite edges of the article and photo-electrically scanning both sides of the article near one edge of the article. If the photo-cell 5 detects a mark it gives an output which is integrated at 15 and a given level operates a trigger to set a bi-stable store 19. This opens the AND gate 22 so that if another mark is detected, a similar store 28 is set. If the marks are on the other side of the article, they are detected by cell 6 and set stores 20, 29. The condition of the stores 19, 20, 28 and 29 indicating the orientation of the article are applied to a code converter 21, and an orientation signal is read out by a signal from a photocell 12 detecting the trailing edge of the article, which signal also resets the stores 19, 20, 28 and 29. The orientation signal may be used to sort the articles according to orientation or may operate re-orientation means. The marks may be black or fluorescent. If the articles are transparent, only one cell can be used; the marks are located nearer to one end of the article than the other and the remaining item of information needed to establish the orientation is derived from the time between sensing the mark and the edge of the article.
