Title: Process for the recovery of ethylene and its homologues from gases
IPC: C07C7/11
Filed: 1933-09-01
Abstract: Ethylene and its homologues are removed from gas mixtures by treatment with a solution containing ammoniacal cuprous nitrate, salicylate, phenolate or cresolate and recovering the dissolved gases by heating and/or reduction of pressure.  The above treatment may be used together with treatment, either before or after, of the gases with other solvents, e.g. kerosene.  The solutions of the ammoniacal salts are prepared by shaking the component salts with an aqueous solution of ammonia in the presence of metallic copper for about 48 hours.  Specifications 304,345, [Class 55 (ii)], and 393,317 are referred to.

Abstract: 1,092,006. Gas analysis. O. H. DRAGER [trading as DRAGERWERK, HEINR & BERNH DRAGER. June 1, 1966 [June 1, 1965], No. 24513/66. Heading G1B. An indicator tube for the simultaneous selective determination of hydrogen sulphide and mercaptans in gas mixtures comprises a layer 3 of lead salts precipitated on granular silica gel, followed by, in the direction of flow, a layer 2 of copper and/or mercury salts and separated therefrom by a previous plate 1, and before the lead salt layer, a breakable ampoule 5 containing a solution of sulphur in benzene or its homologues. In use gas to be tested is passed through the tube and any hydrogen sulphide present will stain the lead salt layer 3 to a length depending on the hydrogen sulphide concentration. Mercaptans present will react with the layer 2 to discolour it but initially the greater proportion of the mercaptans will be adsorbed in the layer 3. After the gas sample has passed, the tube is bent at 6 to break the ampoule 5, the mercaptans then being washed into the layer 2 and the discoloration being intensified by the presence of sulphur. A flexible tube 7 is provided to hold together the two parts formed by bending over the tube at 6. In a described embodiment the salts used are lead acetate, copper acetate and mercuric cyanide, and the sulphur is dissolved in xylene.

A running roll R<2>, Fig. 3, and a reserve roll R<5> are mounted in a support comprising arms 32 fixed to a shaft 3 carrying a sector 6 engaging a worm 9 adapted to be driven by an electric motor. Near each end of the shaft 3 is secured a pair of arms 16, 16<1> carrying spring-mounted web-guiding rollers 22, 23 and cross rods 24, 25 to which the ends of roll-braking belts or aprons 26, 26<1> are secured. Also carried by the arms 16, 16<1> are cross-bars 28, 29 provided with adhesive pads to which the free end of the reserve, wall is temporarily attached. When the running roll is nearly exhausted, paste is applied to the end of the reserve roll and the roll support turned until the end of the new roll is closely adjacent the old web. The press is then stopped, the old web is pressed against the end of the new web to effect the join, and the old web is then severed. The support is automatically stopped when in proper position to join the webs together by the engagement of the sector 6 with a circuit-breaker 420 in the circuit of the motor operating the roll support. After the join is effected, and the press restarted, the support is turned into a position such that the braking belts 26<1> lap round sufficient of the periphery of the roll to apply the desired tension to the web. The rolls may be mounted in the support so as to unwind clockwise or anti-clockwise and may unwind away from or towards the fixed ends of the braking belts. The braking belts or aprons may be weighted near their free end by hanging bags of shot thereto by means of hooks on the bags engaging eyelets in the aprons or an apron 216, Fig. 24, consisting of a series of weighted pockets may be secured to the braking belt. The roll support may be adjusted laterally by means of a rotatably-mounted screw, threaded into one end of the shaft 3, and operated by worm gear driven by an electric motor.
