Abstract: 1,092,346. Molecular sieve process. ESSO RESEARCH & ENGINEERING CO. May 6, 1965 [May 13, 1964], No. 19161/65. Heading B1L. In a molecular sieve hydrocarbon separation process, the sieve is periodically desorbed with a displacing agent at elevated temperatures to obtain a hot displaced hydrocarbon stream, at least part of which is brought into contact with fresh hydrocarbon feed to form a mixture of the displaced hydrocarbon stream and the hydrocarbon feed which is at a temperature higher than that of the feed, the displacing agent is removed from the mixture and the mixture is recycled to the molecular sieve separation zone. In the embodiment of the drawing, hydrocarbon feed preheated at 2 is passed through sieve bed 3. Displacing agent preferably at the adsorption temperature is periodically passed through bed 3 from line 5. Part of the desorbate gas mixture is fed into tower 10 countercurrent to initial feed introduced at 11. Displacing agent is flashed off at the top of the tower at 10, and a combined desorbate - feed stream recycled by line 12 to heater 2. Part of the stream leaving tower 10 may be recycled to the tower via line 13 and heat exchanger 14. In an alternative embodiment there is cocurrent flow in the tower. Separation of various types of hydrocarbon from hydrocorbon mixtures and of sulphur compounds from light naphtha are referred to. Type A or type X sieves may be used. The displacing agent may be CO 2 , SO 2 , NH 3  (exemplified) C 1  - C 5  alcohols, glycols, halogenated hydrocarbons, nitro compounds, or amines of formula NR 1 R 2 R 3  where R 1 , R 2 , R 3  are C 1  - C 5  alkyl radicals.

Abstract: 390,689. Percussive drills. PFLœGER, A., 12, Panoramastrasse, and HAAGE, K., 8, Turmstrasse, both in Esslingen-on-Neckar, Germany. July 8, 1932, No. 19314. Convention date, July 22, 1931. [Class 124.] An internal-combustion percussive tool working on the four-stroke-cycle has a piston 2, carried by a spring 4. In the working stroke the piston uncovers a port 8, enabling the gases to press down the valve 6 and thus opening the cylinder head to the exhaust conduit 9. The compressed spring now performs the exhaust stroke, and passing its equilibrium position, returns the piston downward, sucking in the charge through the valve 11, and handle 12. The next upward movement of the piston compresses the charge, closes the valve 11 and completes the ignition circuit. The handle 14 breaks the ignition circuit until pressure is applied to it to hold the tool to the work.

Abstract: 888,059. Endless conveyers. COAL INDUSTRY (PATENTS) Ltd. May 23, 1958 [June 19, 1957], No. 19323/57. Class 78 (1). In a conveyer comprising an endless belt or other endless loadcarrying member (not shown) which is provided with jaws at each side of the belt, each jaw having a number of gaps for the reception of a driving rope or cable, two flights of a single driving rope 12 are crossed over so as to provide upper and lower flights at both sides of the belt by a device comprising sheaves and deflector pulleys, for laterally deflecting the rope flights, the arrangement being such that the distance between the centres of the rope flights is different on entering and leaving the device. In one embodiment, Fig. 2, there are four single sheaves 10, 11, 13, 14, the sheaves 10, 13 and 11, 14 being coaxial, and four deflector pulleys 15- 18. Two double sheaves 24, 25 are also provided, the top edges of the latter sheaves being arranged above those of the sheaves 10, 11, 13 and 14. The top flight of the rope on one side passes over sheave 24, around sheave 11 and pulley 16 to pulley 17, then around sheave 13 to end sheave 20 associated with terminal belt drum 21. The top flight on the other side is similarly transferred to the sheave 19 on the first side via the sheaves 10, 14 and pulleys 15, 18. The sheaves 10, 14 are of larger diameter than sheaves 11, 13 and the pulleys 15, 18 correspondingly lower than pulleys 16, 17. In a second embodiment, Fig. 4, instead of providing separate sheaves 24, 25 these pulleys are incorporated in the sheaves 10, 11, 13 and 14 by forming the latter as double sheaves. The smaller double sheaves 11, 13 have their axes higher than those of the larger double sheaves 10, 14 so that all the sheaves have their top edges at the same level, providing a continuous flat rope assembly for supporting the upper run of the belt.

Title: Compositions of ethylene copolymers and olefinically unsaturated rubbery polymers
IPC: C08L53/02
Filed: 1960-06-03
Abstract: Materials having high resistance to deterioration by oxygen, light and ozone, and so of use in coating wires and cables, pipes, tyres, foamed rubber articles, rainproof clothing and tents, are made by reacting 5-95% of a copolymer of ethylene and vinyl acetate or vinyl propionate with an olefinically unsaturated rubbery polymer in the presence of a cross-linking agent. The cross-linking may take place in the presence of a polymerizable compound with at least 2 olefinically unsaturated groups, e.g. triallyl cyanurate or triallyl phosphate, at 50-250 DEG C.  The cross-linking agent may be an organic peroxide, free sulphur or an organic compound yielding sulphur at high temperatures, a polyvalent metal oxide or hydroxide, a polyamine. Fillers such as carbon black, silica, calcium silicate, calcium carbonate, calcined magnesia, clay and hydrated alumina may be incorporated. A sheet of the copolymer of ethylene-vinyl acetate or propionate copolymer may be placed in contact with a sheet of the rubbery polymer and the two sheets joined to form a laminate by the action of the cross-linking agent dispersed through one of the sheets. Examples 1-8 are of cross-linking formulations comprising natural rubber, SBR, ABR and polychloroprene and vinyl acetate 20%, 30% and 45%-ethylene and vinyl propionate 30%-ethylene copolymers, other ingredients of the compositions being 2,21-methylene-bis-(4-methyl-6 tert. butyl phenol) and phenol-b -napthylamine, dicumyl peroxide, di-tert. butyl peroxide, sulphur, N-diethylbenzthiazyl sulphenamide, thiuramdisulphide, zinc oxide, magnesium oxide, stearic acid, carbon black, precipitated silicic acid, whiting, titanium dioxide, paraffin wax, dioctyl phthalate, ethylene thiourea, triallyl cyanurate and triallyl phosphate.
