Title: Stabilized polymers of 1,2-monoepoxides and process for preparing them
IPC: C08K5/17
Filed: 1965-02-04
Abstract: Polymers of 1,2-monoepoxides are stabilized by mixing with a mixture of (a) a known amine stabilizer containing aryl radicals, and (b) an aliphatic mono- or polysulphide of the formula RSnR1, where n is 1 to 4, R and R1 are alkyl radicals of 8 to 20 carbon atoms or the group -(CH2)m.COOR1, where m is 1 to 4 and R1 is an alkyl radical of 8 to 20 carbon atoms.  Examples of the amines are heterocyclic amines, e.g. phenothiazine, or aromatic amines, particularly those having 12-30 carbon atoms and 1-3 nitrogen atoms in the molecule, e.g. phenylb -naphthylamine, 4,41-diamino-diphenylamine, N,N-diphenyl ethylene diamine, N-cyclohexyl-N1-phenyl-p-phenylene diamine, N,N1-dicyclohexyl - p - phenylene diamine, N,N1 - diisopropyl - p - phenylene diamine, N,N1-dioctyl-p-phenylene diamine and N,N1i-dodecyl-p-phenylene diamine.  Among the organosulphides listed are di(dodecyl)sulphide, di(octadecyl)tetrasulphide, dithiodiacetic acid dodecyl ester and trisulphide (diacetic acid octadecyl ester). Suitable polymers of 1,2-monoepoxides may be prepared by polymerizing alkylene oxides; epichlorohydrin and other halogen-substituted epoxides; cycloaliphatic epoxides, or epoxy ethers, and by copolymerizing saturated and unsaturated epoxides, such as allyl glycidyl ether with propylene oxide and 1,2-epoxycyclo-octene-(5) with propylene oxide, the latter two copolymers being used in the examples.  The stabilizer is added during processing of the polymer, preferably directly after polymerization, i.e. in the case of the unsaturated copolymers, before cross-linking. Amounts of 0.3 to 3% of the weight of polymer are suitable.

IPC: F01L13/02
Filed: 1925-02-24
Abstract: 248,909. Ricardo, H. R. Feb. 24, 1925. Reversing. - In an engine having sleeve valves positively actuated by rotary mechanism, the direction of rotation of the actuating mechanism is maintained constant when the crankshaft is reversed, and the mechanism is positively engaged and actuated only when there is the required angular relationship between this mechanism and the crank-shaft. In a six-cylinder engine, Fig. 1, each valve A is actuated from a lay shaft D through a skew gear C driving a crankshaft B having a crank pin B' engaging the valve by means of a selfaligning bearing A<1>. The shaft D is driven from the engine shaft through one or other of the bevel gears E engaging a bevel gear E<1> on a shaft E<2> driven through bevel gears F<1>, F<2>. The gears E are loose on the shaft D and are adapted to be engaged by positive clutches G when the engine and lay shafts are in the required angular relationship. The clutches G may be actuated by a hand lever or by a fluidpressure piston K<1>. In order to effect the necessary alteration in order of firing when the engine is reversed, the skew gears C of four cylinders are engaged with the corresponding shafts B in two different positions by means of clutches H<1> carried by members K<3> actuated by fluid-pressure pistons K<1>, which are all controlled from a cook L. Devices such as a magneto M and gear-wheel oil or water pumps, which are operative only in one direction of rotation, may be driven from the lay shaft, and other auxiliary devices, such as an ignition distributor M<1> and plunger pumps. from the shaft E<2>. In a modification, Fig. 5, the lay shaft Q is moved axially for reversing by means of a hand lever V<2> having ,a projection V<3> connected by springs V<4> to the arms V<5> of a lever V engaging the lay shaft. Four of the skew gears R are. fixed on the lay shaft to move axially on reversal, effecting relative rotation of the transverse valve-actuating shaft S'. The two remaining skew gears R<2> are splined on the lay shaft and prevented from .axial movement by the adjacent bearing U. For liquid-injection engines. a fuel pump W is actuated from each of the shafts S'. In an eight-cylinder engine, the cylinders are arranged in two groups of four, the cranks of one group being in a plane at right angles to those of the other group. A separate cranked lay shaft is used for each group, the cranks of one lay shaft being at 45‹ to those of the other; a phase-changing connection is interposed between the two lay shafts, so that one of them is turned through a right angle on reversing. The lay shafts are driven from the engine shaft through sprocket gearing and a reversing gear.

Abstract: 1497342 Extruding foamed sheaths around filamentary cores WESTERN ELECTRIC CO Inc 7 Feb 1975 [7 Feb 1974] 5247/75 Heading B5A [Also in Division C3] An electrical conductor wire 17, Fig. 1, is sheathed, by extrusion from a die head passage 19, of a plastics 20 which, at least around part of the periphery of the sheath, is foamed on issuing from the passage 19 by a fluid foaming agent which has been injected into the plastics, through a porous wall 25 of a die head core tube 11 through which the wire 17 is guided to the passage 19. The extent to which foaming occurs throughout the thickness of the sheathing may be controlled by various specified parameters, including the temperature of the wire and fluid cooling of the sheathing downstream of the passage 19, to produce a sheathing varying from a substantially uniform cellular structure throughout, to a sheathing having an unfoamed exterior around a uniform inner cellular section, as in Fig. 5. The wall 25 may be of porous stainless steel, or sintered porcelain, and may comprise a washer, as in Fig. 1, forming part of a tapered core tube nose and clamped to the core tube body by a tapered metallic nose pieces 27 threadedly engaged upon a body extension 24, or the wall 25 may comprise a tapered nose piece on the extension 24 of Fig. 1 and extending to the downstream end of the core tube, Fig. 2 (not shown), or the wall 25 may extend to the downstream end of the core tube from a location adjacent that (23) at which the plastics enters the die head, Fig. 3 (not shown). The gaseous foaming agent is delivered from a variable pressure regulating means to the porous wall 25 along passages 30, e.g. eight passages, circumferentially spaced about the tube 11, and which may be curved slots which, in a modification, Fig. 3 (not shown), may be continued into the porous wall. The wire is guided by a diamond 31 in the core tube nose, which defines with the surrounding die surface 18 a passage for the plastics of decreasing depth toward the passage 19. The foaming agent may be injected at a pressure of 50-100 p.s.i. greater than that of the plastics adjacent the porous wall 25, and may be injected into plastics containing a chemical blowing agent.  The porous wall 25 may extend continuously around the core tube or may comprise porous segments 25a, Fig. 6, intermediate segments 25b of non-porous material. Alternatively, the wall may comprise a single segment 25a, producing a sheathing having only a corresponding arcuate foamed portion. The plastics may comprise polyethylene, polystyrene, polyvinyl halide compounds, copolymers of polyvinyl chloride and polyvinyl acetate, or nylon. The fluid foaming agent may comprise carbon dioxide, argon, neon, helium, nitrogen, ammonia, and various specified organic gases.

Title: Removal of oxygen from olefines
IPC: C07C7/148
Filed: 1943-04-03
Abstract: Gaseous mixtures consisting substantially, e.g. 80 per cent or more, of olefines, especially ethylene, and a small proportion, generally less than 1 per cent by volume, of oxygen are purified by passage at a pressure of at least 20 atm. through one or more vessels containing one or more of the following metals or their oxides: copper, nickel, silver, gold, platinum, and palladium. Reduced oxides of copper or nickel, especially reduced granular fused oxides, are prepared. Reduction of the used catalyst is necessary at only infrequent intervals if at all.  Preferably, pressures of 50-2000 atm. are used at 30-150 DEG  C.  At higher temperatures such as 100-200 DEG  C., lower pressures should be used, e.g. 20-100 atm., with copper and nickel.  A space velocity of 500-20,000 is suitable.  Two or more catalyst tubes with intervening traps, generally at a lower temperature and in some cases containing absorbents, are preferably used in accordance with the process of Specification 560,497.  In examples: (1) a copper-lined tube containing granular reduced copper oxide at 90 DEG  C. is used, ethylene containing 180 parts per million of oxygen being passed through at 1000 atm. and a space velocity of 1200. Oxygen is reduced to 52 parts per million and reactivation of the catalyst is unnecessary; (2) Raney nickel is used at 1000 atm. and 30 DEG  C.
