Abstract: 1469254 Hydrogenated styrene oligomer compositions BASF AG 6 Aug 1974 [7 Aug 1973] 34581/74 Heading C3P Compositions suitable for use as additive concentrates for thermoplastics materials comprise (A) 5 to 90 weight per cent of additive, (B) 95 to 10 weight per cent of a hydrogenated " styrene " oligomer of average molecular weight 300 to 10,000 and (C) 0 to 60 weight per cent of a styrene polymer. The oligomer may be derived from styrene, α-methyl styrene and/or vinyl toluene, and may be hydrogenated in the presence of conventional catalysts. The additive may be a pigment, brightener, filler, flameproofing agent, stabilizer, antistatic agent or lubricant. The concentrates may be blended with styrene polymers, polyethylene, polypropylene, polyvinyl chloride or polymethyl methacrylate. In examples polystyrene is blended with (1) titanium dioxide and a concentrate of hydrogenated styrene oligomer and phthalocyanine blue, and with (2) carbon black and a concentrate of hydrogenated styrene oligomer and titanium dioxide.

Title: Improved separator for a mixture of heavy and light gases
IPC: B01D53/22
Filed: 1945-12-21
Abstract: <PICT:0611068/III/1> <PICT:0611068/III/2> A separator for heavy and light gases, which is formed of at least two enclosures separated from one another by at least one porous partition, the first enclosure being connected to a gas mixture entry and a heavy gases discharge, and the other enclosure being connected to a light gases discharge, is characterised in that the separator comprises means (electric heating strip 6 and cold water spray 5) for maintaining a temperature difference between the two enclosures, the temperature of this said first enclosure being the lower.  Concentric tubes 1 and 2 of metal, Fig. 1, and 3 of porous material (e.g. porcelain, Eternit, earthenware, or infusorial earth) provide annular spaces 9 and 10, the latter being gas-tight.  Electrical heating resistance 6 is fixed between insulators 7, the outer tube 1 is immersed in cold water 4 and a pump-fed cold water spray 5 plays on the outside of tube 1.  A thermally insulating partition 8 separates conduits 11 and 13. The gas mixture ascends central column 2 and descends in the annular space 9.  Light gases pass through the porous tube 3 and travel towards hot tubes 2 and through orifices 12, whilst the heavy gases (e.g. CO2) leave by apertures 13.  Gases of intermediate density collect in dome 14 whence they are re-admitted to the apparatus or to a second identical apparatus. Pressure in space 10 may be lower than in the rest of the apparatus.  In the construction of Fig. 2, a cylinder 17 of porous plugs 18 separates an outer space 19 from a central chamber which the gas mixture enters by pipe 21 and valve 23. A piston 25 with porous plugs 18 is given a rapid suction stroke and a slow compression stroke so that light gases pass through wall 17 and gases with a high rate of diffusion through porous plugs inserted more particularly in the bottom of the cylinder.  Residual gases are expelled through valve 24.

[Class 7 (ii)] Additional internal - combustion or other power units B, C are clutched in successively in series with the unit or units A already in use and conjointly with the opening of the respective carburetter throttles in response to an increase of load. The operating rod 8 carries projections 13 engaging successively with slots 14 in discs 10, 11, 12 which are connected by links 15, 16, 17 with the carburetter throttle valves and by slots, pins, and links 22 with the movable members of the clutches 6, 7. The movement of the discs is limited by underside projections 8<a> on the rod 8 which engage flats 10<a> on the discs, while by forming parts of the slots 21 as arcs of which the centres are coincident with the axes of the discs, the movements of the clutch operating links 22 are co-ordinated with those of the throttle levers. Units may be clutched in successively by the arrangement shown in Figs. 5 and 6. The shaft of each engine unit is in two parts 1, 1<a> connected by pairs of levers 92, 93 mounted on the two parts, the drive being transmitted through springs 97. Increase of load causes compression of the springs and the radial movement of brake members 95 pivoted through links 94 on the levers 92, 93. The members 95 engage the rim of a disc 98 and slide it axially along the shaft 1, this movement being transmitted through linkages 102, 104 to clutch members for engaging the adjoining engine unit. Heating cooling-water.-The water-jackets of idle engines B, C are heated by exhaust from the engine A. A flap-valve 50 connected by a link 51 to the disc 11 controlling the engine B, either directs all exhaust from the engine A through pipes 53 around which the cooling water circulates, or diverts it through the outer part of casing 46 to the exhaust manifold 49. The three sections of the radiator communicate at their bases ; from the outer sections, pipes 56 provided with branches 57, 59, communicate directly with the water-jackets of the three engines. Branches 58, 60 lead to the exhaustheated casings 46<a> with outflows 64, 65 to the adjoining engines. There are also cross-connecting pipes 54 between the cylinder jackets on opposite sides of the crank shaft. The outlet 63 from the engine C leads to the top of the central compartment of the radiator. The fan and the inlet and outlet valves are operated by skew-gearing from the outer-half of the clutches 6.
