A chamber for rotation about a rotational axis to separate blood components includes first and second spaced apart side walls forming a separation zone. Blood conveyed into the separation zone separates into a first region of cellular components (96), a second region of plasma (98), and an interface region (58) between the first and second regions. An outlet conveys the second region of plasma fro...

Blood processing systems and methods create dynamic vortex flow conditions (130) within a processing chamber (40) by conveying blood into a separation path that extends circumferentially about the rotational axis along an entry path that extends generally parallel to the rotational axis. The vortex flow conditions perfuse blood into the separation path for separation into component parts. The syst...

A tube holder secures to the rotating processing chamber of a centrifuge tubing that conveys fluid to or from the chamber. The tube holder is part of a carrier that is connected by a pin to a support on the processing chamber. The support has walls defining an enclosure. The carrier swings about the pin on the support between an opened position free of the enclosure and a closed position captured ...

The invention relates to a process for the preparation of rigid foams containing urethane groups or urethane and isocyanurate groups, by reacting   a) organic and/or modified organic polyisocyanates with   b) at least one relatively high-molecular-weight compound containing at least two reactive hydrogen atoms, and optionally   c) low-molecular-weight chain extenders and/or crosslinking agent...

Recycling of compact or porous (e.g. foamed) plastics consisting wholly or partly of polyurethane is effected by working-up the starting material to give a mixt. of low OH no. and then conventionally converting this to the end-prods.. The process comprises (i) either (a) swelling the starting material (e.g. polyurethane scrap) in a suitable swelling agent and processing it to give a flowable gel p...

Concentrates produced by melt processing a branching agent and a polyester carrier are disclosed. The concentrates are useful in melt processing polyesters. The concentrates contain sufficiently high concentrations of a branching agent to minimize the formation of crosslinked compounds in the concentrates. Process for using the concentrate also is disclosed.

Body lumens such as blood vessels are selectively occluded by mechanically collapsing the blood vessel and subsequently applying energy or other occlusive conditions within or adjacent the collapsed region. For example, vessel collapsing mechanisms can include spreadable opposed elements, reciprocating jaw mechanisms having penetrating elements, and devices for applying negative pressure to collap...

An adaptor cable and methods are provided for use with electrosurgical bipolar instruments and standard commercially available electrosurgical generators that reduce arcing. The adaptor cable limits the peak-to-peak voltage developed between the electrodes of the electrosurgical instrument by providing a minimum load impedance between the output terminals of the electrosurgical generator.

Thin-walled articles, particularly sheets of film including at least one first layer of polymeric material including starch and at least one second layer of hydrophobic material, are characterised in that the second layer includes a natural or synthetic wax or a mixture of waxes.

A multiple-layer film comprises an oriented propylene polymer substrate having on opposed surfaces thereof, respectively, a first vinylidene halide copolymer having a Tg of up to 25 DEG C and a molecular weight not exceeding 135,000 and a second vinylidene halide copolymer having a Tg greater than that of the first copolymer. Such films offer excellent sealing profile, blocking resistance, gas-bar...

Perfezionamento ad un metodo e relativo prodotto per la depurazione particolarmente delle acque inquinate da fosforo, azoto, metalli pesanti e solventi clorurati, ammettendo in esse, a seconda del tipo di abbattimento, un composto liquido sostanzialmente costituito da acido umico e fulvico, od acido umico e fulvico più un sale metallico, e più in particolare: l'acido umico e fulvico essendo estrat...

A process is described for the production of aqueous dispersions involving removal of liquid(s) from an optionally multiphase liquid mixture by means of membrane distillation, e.g., transmembrane distillation or pervaporation.

Predominantly water based adhesive compositions and primers comprising: A) 2 to 50 parts by weight of a solution in a non-ionic surface active agent of one or more chlorinated polyolefins; B) 50 to 98 parts by weight of a component selected from: 1) an aqueous dispersion comprising from 35 to 65 parts per hundred by weight of vinylacetate-ethylene copolymer and 2) an aqueous solution compris...
