In a turret winder, for traverse-winding cops from continuously- delivered yarn, each cop 28 is supported adjacent a threaded region 38 or 40 which draws yarn, extending to a wound package when indexed to the unloading station, towards the empty cop 28.

A method of producing direct reduced iron from pellets, lumps and fines of iron oxide. A mixture of iron oxide raw material is introduced to an apparatus which separates the lumps and pellets from the fines. The lumps and pellets are then introduced to a shaft furnace for direct reduction to iron. Fines are conveyed to a series of circulating fluidizable beds which allows intimate contact with red...

A method and a device for separating a component, such as fibrin I from blood, by centrifugation. The method involves feeding of blood admixed an anticlotter to a first annular chamber in a device, where the annular chamber is defined by a cylindrical outer wall and a cylindrical inner wall, both walls extending coaxially about a common axis, as well as by a top wall and a bottom wall, where the t...

A sintered hardmetal (cemented tungsten carbide) product has a core made of a first grade of cobalt or nickel bonded cemented tungsten carbide with a surface layer of a second grade of distinctively different cobalt or nickel bonded cemented tungsten carbide. The first grade, or core, is generally a relatively tough (impact resistant or shock resistant) grade of cobalt or nickel bonded hardmetal w...

Thermoplastic polyurethanes are prepared by reacting (a) isocyanates with (b) compounds reactive toward isocyanates, in the presence or absence of (c) chain extenders, (d) catalysts and (e) customary auxiliaries and additives and adding crosslinked polyurethanes in comminuted form before, during and/or after the reaction.

An expanded film suitable for plastic coverings for greenhouses and tunnels and for heated mulching of soil, with improved greenhouse effect compared to close-packed neutral films made of the same base polymer, comprising one or more layers of expanded plastic material, at least one of the layers being constituted by an alpha -olefin and a vinyl ester copolymer. Particularly significant are ethyl...

A fiber having increased cut resistance is made from a fiber-forming polymer and a hard filler having a Mohs Hardness Value greater than about 3. The filler is included in an amount of about 0.05% to about 20% by weight. In preferred embodiments, the fiber-forming polymer is poly(ethylene terephthalate) or a liquid crystalline polyester comprising monomer units derived from 6-hydroxy-2-naphthoic a...

A molded closure for a liquid container comprising a thermoplastic elastomer and a blowing agent. The molded closure is particularly suitable for use as a synthetic wine cork in a wine bottle. The molded closure does not permit passage of oxygen into the container, does not absorb oxygen from the contents of the container, can be removed from the container using a corkscrew without significant exp...

Films, containers made of high density polyethylene, and articles made therefrom exhibit, for a given density, improved resistance to water vapor transmission. The high density polyethylenes are produced in a metallocene-catalyzed production process. Alternatively, for equivalent water vapor transmission rates (WVTR) an article formed in accordance with the invention will exhibit improved physical...

An aqueous composition for coloring cement based compositions comprising water, pigment, a suspension enhancing agent and latex polymer solids.

An expanded shaped product with improved flexural compressibility and surface properties comprising starch and a hydrophobically modified acid anhydride or its acid hydrolyzed counterpart and the method of preparing such product by extrusion.

Method for the thin film deposition for plastic substrates, in which the deposited film is realised with a mixed organic-inorganic structure, particularly to be realised in a vacuum deposition plant of thin films, through PE-CVD and sputtering techniques. By this method, in the case of a multilayer structure, modifying the process parameters, the deposition of desired layers with different refract...
