Abstract: 284,402. Koerner, E. Oct. 27, 1926. Cigarette-making machines. - Spreading and stripping rollers and like devices are divided axially, the divided portions being actuated with a definite phase difference. Arms 9, Fig. 2, are loosely mounted about a shaft 8 and carry a multiple crank shaft 10 driven from the shaft 8 by chain gearing. Each crank pin serves as a bearing for one of the picker rods 14, the stems of the rods working in slots formed in a bar 15 located in bearings 16. The arms may be raised or lowered, and are secured in position by bolts which pass through an extension in each rod into a slot in the framework. In a modification, a stripping roller is constructed in four sections. A central shaft 44, Fig. 4, is surrounded by two hollow shafts 42, 43 to which are pinned the two roller sections 39, 40. The two outermost sections 38, 41 are integral with sleeves 65, 66.

Abstract: 1414652 Acrylonitrile polymer filaments E I DU PONT DE NEMOURS & CO 16 Oct 1972 [14 Oct 1971] 27906/75 Divided out of 1414651 Heading B5B [Also in Division C3] Filaments of acrylonitrile polymers containing 80-100% by weight acrylonitrile units and 0-20% by weight of units of one or more comonomers have a sheath extending inward from the surface of the filament with a thickness of from 5 to 50% of the distance from the outer surface of the filament to the central axis of the filament, the sheath having a positive density gradient wherein the highest density is at or near the surface of the filament and having substantially no optical voids. The exemplified comonomer units are derived from one or more of methyl acrylate, sodium styrene sulphonate, styrene, ethylene, 2-methyl-5-vinylpyridine and vinyl acetate. The filaments are produced by extruding a composition containing the acrylonitrile polymer and water, wherein the water is present, completely or partially, in the form of a hydrate with the nitrile groups of the polymer, through an orifice at a temperature of from 25 C. below to 10 C. above the temperature of hydration of the acrylonitrile polymer). (The hydrated polymer compositions are described and claimed in Specification 1,414,651. The extruded filaments comprise a core containing voids having lateral diameters of from 0À05 to 1 micron in a concentration of between 10<SP>5</SP> and 10<SP>7</SP>/mm.<SP>2</SP> of core cross-section. When the filaments are drawn, e.g. to 200% or more of their as-spun length, the sheath develops discrete, longitudinal striations on the outer surface or skin and the voids in the core are elongated and reduced in diameter, the drawn filaments thereby developing a positive form birefringence. If the filaments are heated, the core voids can be reduced to less than 0À05 micron in diameter and the birefringence disappears.

Abstract: Plastic foils having a cellulose base are prevented from sticking by adding to the plasticizer an oxide aerogel of a particle size of 0.05 microns or less, formed by thermal decomposition of a volatile metal or metalloid compound in the vapour state in the presence of a hydrolysing agent.  The amount of oxide aerogel incorporated into the foil is preferably 0.1-0.5 per cent by weight and the preferred aerogel is silica aerogel.  The aerogel may be produced as described in Specification 726,250, [Group III].  In an example, a film formed by extruding viscose solution is stretched, washed and passed through a plasticizer bath of 540 litres of water, 60 litres of glycerine and 1 litre of a 15 per cent aqueous dispersion of a silica aerogel produced from silicon tetrachloride in the vapour state which has been thermally decomposed in the presence of a hydrolysing agent. The foil is squeezed and dried and has a non-sticky surface.
