A single needle extracorporeal plasmapheresis circuit makes use of a membrane filter (1) that separates, under the effect of TMP -transmembrane pressure,- plasma from blood. The filter (1) has two connectors (1a,1b) on the blood side, one of which (1a) is connected to a line ending with a single needle. Blood pump (4) is positioned along this line. The other connector (16) is connected to a second...

A branch history table (BHT) is substantially improved by dividing it into two parts: an active area, and a backup area. The active area contains entries for a small number of branches which the processor can encounter in the near future and the backup area contains all other branch entries. Means are provided to bring entries from the backup area into the active area ahead of when the processor w...

A concrete roof tile is coated with an unfilled or aggregate- and/or pigment-filled film of a copolymer containing (a) from 0.03 to 2% by weight of tin in the form of a polymerizable organotin compound (b) from 0.5 to 5% by weight of (meth)acrylic acid, (meth)acrylamide and/or vinylsulfonic acid and (c) from 0.1 to 5% by weight of carbonyl-containing monomers crosslinked with certain dicarboxodihy...

A device comprising a solid or powdered concrete admixture contained in a water-soluble container such that when the container and its contents are introduced into a wet mixer and agitated for a period of time, the water-soluble container is dissolved and the contents are released into the wet mixer. A separate water-insoluble receptacle is used to house and store the water-soluble container and i...

A sterile aqueous solution containing 0.02 to 30 g per 100 ml solution of a mixture of isomalto-oligosaccharides comprising (a) 0-15 percent by weight of isomaltose, (b) 20-65 percent by weight of isomaltotriose, isomaltetraose and isomaltopentaose, each of these oligosaccharides being present in an amount of at least 5 percent by weight and at most 25 percent by weight, (c) 20-65 percent by weigh...

A method of continuously mixing and kneading pulverulent bodies such as pulverized coal, oil coke to prepare a slurry thereof. Pulverulent bodies supplied continuously at a fixed rate from a supply tube are spattered and dispersed by a rotary mixing disk rotating in a mixing chamber covered with a base plate. A flow of a main liquid is directed as an annular overflow film downward along an overflo...

PURPOSE:To attain data transmission between multiplex nodes on the occurrence of a fault by varying a voltage of a signal transmission line when a fault of the signal transmission line is detected. CONSTITUTION:Signal transmission lines are composed of at least three signal transmission lines A-C, multiplex nodes 30, 40, 50, 60 detect at least one signal transmission line among the signal transmis...

A process for hydrocracking 343 DEG C <+> feed containing polycyclic aromatics to form a lube base stock having enhanced oxidation stability and viscosity index is disclosed. The hydrocracking catalyst is a layered silicate, such as magadiite, which contains interspathic polymeric silica and interspathic polymeric oxides of one or more elements selected from the group consisting of Al, B, Cr, Ga, ...

A laser-imageable assembly comprising a transparent substrate having on a surface thereof an energy absorbent transfer layer comprising particles which absorb laser energy dispersed in a heterogeneous resin layer. Heterogeneity may be achieved by appropriately drying the coated substrate. The assembly may also comprise one or more additional layers of primer, protective and lubricant coatings. A p...

The present invention relates, as new industrial products, to the benzopyran-2-one-ss-D-thioxylosides of formula: in which: - X represents a sulphur atom or an oxygen atom, - R1 and R2, which are identical or different, each represent a hydrogen atom, a C1-C4-alkyl group, a halogen atom, a trifluoromethyl group, a phenyl group, it being possible for R1 and R2, taken together, to form ...

It is possible with the aid of a Bacillus species or the appropriate enzymes obtained therefrom to degrade phosphoglycolipid antibiotics. The degradation products of the moenomycins have antibiotic activity or can be used as building block in the synthetic preparation of transglycosylase inhibitors.

Adjacent edges of unvulcanised rubber are rolled so as to join them together. A flexible strip is placed over the two edges and removed after the rolling operation. During the latter it is pressed against the edges simultaneously, the rollers being moved along the edges from one end to the other. Each roller can comprise a metal core with rubber cladding of selected hardness.
