Abstract: A composition of matter suitable for increasing the viscosity of liquids comprises tendrillar carbonaceous material (TCM) having a ultra low bulk density of less than about 01 g/cm<sup>3</sup> and comprises intertwined tendrils having a diameter (number average) of from about 0.05 to about 0.2 micron and a length (number average) to diameter (number average) ratio greater than about 10, the tendrils comprising carbon fibers and an iron metal component dispersed throughout the carbon fibers as nodules that are intimately associated with and at least partially bonded to the carbon fibers, the tendrillar carbonaceous material comprising from about 0.1 to about 5% by weight iron. The TCM can be used as a viscosifier and for suspending solids in such applications as drilling muds, lubricating oils and greases. The TCM can be prepared by disproportionating carbon monoxide in the presence of iron contained in a blend of (1) previously formed TCM and (2) iron containing particles.

Abstract: The invention relates to a delivery device for running yarns, especially for feeding these to yarn-processing machines, such as, for example, for the insertion of the weft yarn into a weaving machine, in which device the yarn is fed tangentially to a drum connected to a rotary drive and is taken off from this again by means of a draw-off force acting on the far side of the drum, the yarn looping round only part of the circumference of the drum rotating at a circumferential speed higher than the yarn draw-off speed and being capable of being brought, by means of the draw-off force applied tangentially relative to the drum, into slipping engagement with the drum outer surface, and at least two drums adjacent to one another in an axis-parallel manner being so subdivided by fixed partition walls that each of the drums forms a plurality of regions, located in succession in the direction of the drum axis, for part looping by the yarn, in such a way that the yarn passes over from the region of the drum onto the region of the other drum. To optimise the operating mode of a delivery device of this type, the invention proposes that the drum outer surface have a radially outward-directed annular collar (R) in alignment with the plane of each of the partition walls (47, 48).

Abstract: An apparatus for pressurised screening of a fibre/liquid suspension to separate the fibrous fraction into an accepts portion and a rejects portion, has a housing (60) having an inlet (120) with a trap (90) for heavy and large material, an accepts outlet (110), a rejects outlet (100), and a dilution liquid inlet (105). A hollow cylindrical screen (10) having an open top and bottom communicates with a fibrous suspension inlet chamber (70) and a rejects outlet chamber (80). Accepts fibres in the suspension pass through apertures (15) in the screen to an accepts chamber (75) and are discharged through the accepts outlet. Rejects discharge through the rejects chamber. A rotor (30) having at least four regions, a closed top, and a bottom mounted drive mechanism (150) is coaxially mounted within the screen. Hydrodynamic pulses are induced in the suspension in the screening region by a pattern of bumps and/or depressions (36, 38) impressed upon the rotor surface. The fibrous suspension is maintained at a relatively constant consistency within the screening region by the pumping action of the rotor and by providing dilution liquid to counteract thickening of the suspension. A dynamic bar screening device (40) directs stones and other large objects out of the fluid stream and into an annular trap and also deflocculates the suspension. <IMAGE>

Abstract: The use of falling-film evaporation and a concentration means such as centrifugal separation to dehydrate and concentrate a water-in-oil polymer emulsion or suspension is disclosed. In a preferred embodiment, a water-in-oil polymer composition containing less than about 25% active polymer solids is dehydrated in falling-film evaporator to produce an evaporator concentrate containing less than about 5.0% water. The evaporator concentrate then flows to a separation device such as a centrifuge, wherein oil is removed to produce a composition that is substantially a polymer and emulsifying surfactant-in-oil composition containing in excess of about 60 weight % polymer solids. The centrifuge raffinate may optionally be treated in a second separation means to capture additional polymer solids, with optional recycle of the oil-rich raffinate. The concentrated polymer composition is preferably stabilized with a steric stabilizer to produce a free flowing liquid product.
