Plasmapheresis apparatus is disclosed which comprises a unique combination of blood withdrawal, separation and return means, together with automatic cycle control means. This apparatus can withdraw whole blood from a donor, separate it into plasma and non-plasma components, and return the non-plasma component to the donor while the donor remains connected to the apparatus throughout the entire pro...

The compounds represented by the structural formula wherein n is an integer of from 1 to 4, A, B and C each independently represent hydrogen, a lower alkyl having from 1 to 5 carbon atoms or a lower alkenyl having from 3 to 5 carbon atoms, provided that the sum of the carbon atoms in A, B and C is no more than 7, R1 and R2 each independently represent hydrogen or a lower alkyl having from 1 to 5 c...

A process for coating hollow metal articles. Water-borne primer/ surfacer is sprayed onto selected external surfaces and the article is dried without fully curing the primer/surfacer coating. The remaining surfaces are then electrophoretically coated with primer and the article is baked to at least partially cure both the sprayed and the electrophoretically deposited primer coatings. A top coat...

The creel comprises three superposed levels (1, 2, 3) each constituted by a rigid horizontal plate (4), supporting and holding in a vertical position two rows of yarn packages (6), and a connecting frame (5) fitted with thread guides for withdrawing (paying-out) the yarn. The plates and frames of the creel can be removed. By means of these elements, it is thus possible to produce a creel for suppl...

A tire curing membrane has a pattern of interconnected ribs integrally molded on its inside surface. The ribs collectively define a pattern of closely fitted, approximately equilateral hexagons with no non-hexagonal interstices.

A closure device for fluid-tight closure of an opening of a fluid container. The device comprises a casing part (1) and a cap part (2). These parts are injection molded from different plastic materials, preferably from PVC and polypropylene, respectively, one partially against the other. A tubular portion (12) of the cap part (2) intrudes sealingly into a substantially cylindrical hollow space bet...

A method and apparatus for use at the stage of a radial tire building process at which a tread and breaker, and sidewall rubbers, are added to the expanded carcass. A tread assembly is built, comprising tread rubber breaker and sidewall rubbers and is then located around the carcass which is then expanded into the tread assembly. A tread assembly former has a central portion expansible to bring si...

A tire and wheel assembly in which one or more ingredients of a lubricant composition are enclosed separately from other ingredients, all the ingredients being enclosed in enclosing means which, on deflation of the tire, will release them into the inflation chamber of the assembly to form the composition.

A ski boot heel release binding, comprises a mounting base plate which is adjustably connected to a toe jaw part via a touring plate. The base plate includes an upstanding portion which supports a transversely positioned heel mounting pivot. A heel holder includes a slot which is vertically elongated on the holder in the closed position which forms a guide for the mounting pivot to pivotally mount...

A heel retainer for a safety ski-binding comprises a housing for attachment to the ski and a holder for engaging the sole of a ski boot. The sole holder is pivoted to the housing by a shaft displaceable in slots of the housing extending substantially parallel to the ski and is held in a sole-engaging or sole-releasing position by a first spring. A second spring biases the pivot shaft in the slots ...

Compositions having rodenticidal activity are disclosed which are constituted by a solution of a compound having anti-coagulant activity and which is an indane dione or a 4-hydroxycoumarin, preferably chlorophacinone, diphacinone, bromadiolone or coumachlor, in a glycol in admixture with a volatile co-solvent, preferably acetone or dichloromethane, which increases the solvent activity of the glyco...
