Abstract: 1,196,658. Purifying combustible gases. METALLGESELLSCHAFT A.G. 3 Oct., 1967 [14 Oct., 1966], No. 44924/67. Heading C5E. H 2 S and CO 2  are removed from fuel gas or synthesis gas in a process which comprises passing the gas under pressure in series through two absorbers 4, 5 (for H 2 S, CO 2  removal respectively) where the gas is contacted with an organic scrubbing liquid, e.g. methanol, acetone, toluene or xylene, at a temperature below 0C. Each absorber has a regeneration stage 7, 9 having flashing stages 71, 73, 91, 94, 93, and reabsorbtion stages 72, 92. Clean scrubbing liquid enters the absorber 5 at 13 and apart from a portion recycled through a cooling cycle 54, 15, the CO 2 -containing liquid is divided into two portions which re-combine at 74, namely: 16, 4, 17, 71, 22; and 29, 91 32, 93, 24, 73. H 2  and CO flashed off at 71 and 91 are returned through a compressor 6 to the gas inlet 10, while pure CO 2  flashed off at 93 leaves the apparatus at 36. The reabsorbers 72, 92 remove CO 2  from the flashed-off gases, using partly regenerated scrubbing liquid from 94, via 19, 20. The recombined liquid which still contains H 2 S, is passed via 27 for complete regeneration by boiling in column 8 and recycling through heat exchangers 85, 74, 95 to 13, gas containing H 2 S leaving at 28. Further H 2  and CO leaves at 25. Two other circuits are shown, namely line 26 for delivery of gas and vapour containing H 2 S to the absorber 7 to remove H 2 S from the gas, and line 34 for delivery of CO 2  containing liquid to flashing stage 94 and thence via 97 back to the absorber 5.

Examples refer to homo-polymerization and co-polymerization of butadiene and piperylene. Generally mentioned are butadiene-1,3; pentadiene-1,3; isoprene; hexadiene-1,3; heptadiene-1,3; octadiene-1,3.  The polymerization may be carried out at temperatures from less than 0 DEG  to about 100 DEG  C., and pressures from subatmospheric to about 10 atmospheres, in a solvent which may be a C4 to C10 saturated aliphatic hydrocarbon or an aromatic hydrocarbon, and using 0.01 to 0.5 parts catalyst per 100 parts monomer; 0.005 to 0.3 wt. per cent catalyst based on total reaction mixture. Example 5 relates to curing polypiperylenes.ALSO:A catalyst system comprises a titanium halide compound in which the titanium has valency less than 4, a Group III B or IV B metal iodide intimately mixed with the titanium halide, and as co-catalyst a Group I-III metal alkyl or metal alkyl hydride, the molar ratio of metal iodide to titanium halide varying from 0.5:1 to 10:1 and the molar ratio of alkyl groups in the co-catalyst to iodine atoms in the metal iodide varying from 1.4:1 to 3:1 when the metal in the metal iodide has valency 3, and from 1.5:1 to 4.5:1 when the metal in the metal iodide has valency 4.

Abstract: 1,219,278. Impulse transmitters. GENERAL ELECTRIC CO. Ltd. 26 Nov., 1968 [5 Oct., 1967], No. 45549/67. Heading H4K. A telephone dial mechanism has a restraining member which is moved into a position where motion of one of the contacts of the impulsing springset is stopped, after the dial has been set and released, so that impulses will be transmitted when a lobed cam actuator rotates. Attached to the main shaft is a finger-plate operating member and a main gear wheel 22 which is coupled through gearing to a further gear wheel which is freely rotatable on the main shaft and carries cam 38. Restraining member 40 is also mounted on the main shaft and is movable between stops 44, 46. In operation when the dial is set the cam wheel moves clockwise so member 40 is moved against stop 44 and the contact springs 66, 68 remain closed and move together as the cam rotates. When the dial is released cam 38 moves anticlockwise to move member 40 towards stop 46 where it will engage under contact spring 66, when the springs are on the nose of the cam, and thereafter as the cam turns impulses will be transmitted (Fig. 6). The "lost motion" movement of member 40 from stop 44 to stop 46 provides the required interdigital pause. In the modification shown in Fig. 9 the restraining member 140 has arms 103, 106 which co-operate with the impulsing springset 166, 168 and toothed wheel 107 respectively. When the dial is set, wheel 107 turns anticlockwise to drive arm 106 of member 140 against stop 119 so that in operation "lost motion" occurs while member 140 is driven by wheel 107 to the position shown and after a further pause the spring- set is lifted and arm 103 engages under contact arm 166 so that impulses are transmitted. Contacts 74 and 72 provide the "off normal" contacts. Also connected to main gear 22 is a governor which comprises bob weights which engage the sides of a frusto-conical recess in the front housing (18). The governed speed can be altered by axially moving the governor shaft. The casing, gears and the like of the dial assembly may be made of plastics material.
