The invention provides methods for the systematic analysis of the structure and function of polypeptides by identifying active domains which influence the activity of the polypeptide with a target substance. Such active domains are determined by substituting selected amino acid segments of the polypeptide with an analogous polypeptide segment from an analog to the polypeptide. The analog has a dif...

The liquid algicidal composition contains, as component A: 2-methylthio-4-cyclopropylamino-6-tertiary-butylamino- 1,3,5-triazine, as component B: at least one biocidal quaternary ammonium or phosphonium compound, as component C: at least one solvent which is miscible with water, the composition containing 10 to 80% by weight of components (A + B), and the ratio by weight of A:B = 1:(2 to 100).

A vinyl-skin-covered polyurethane-foamed article is disclosed, comprising a polyurethane foam core, a vinyl skin covering the polyurethane foam core, and a barrier layer between the polyurethane foam core and the vinyl skin that reduces the migration of polyurethane foam components into the vinyl skin and reduces the migration of vinyl skin components into the polyurethane foam core. In a particul...

PCT No. PCT/FR89/00559 Sec. 371 Date Apr. 29, 1991 Sec. 102(e) Date Apr. 29, 1991 PCT Filed Oct. 26, 1989 PCT Pub. No. WO90/04547 PCT Pub. Date May 3, 1990.A package for a liquid which is purified includes a neck with a lock-chamber slidable therein. The lock-chamber includes a purifying substance through which the liquid passes when dispensed. At one end of the lock chamber, a plug is positioned ...

Anthracycline glycosides of the general formula (I): wherein R1 represents a hydrogen atom or a hydroxyl group, one of R2 and R3 represents a hydrogen atom and the other of R2 and R3 represents a hydrogen atom or a hydroxyl group; and pharmaceutically acceptable acid addition salts thereof are antitumor agents. These glycosides may be prepared from a daunomycinone derivative of formula (II)...

Compounds of general formula: (I) where A, B, G, R2, R3, R4 and are defined in the description. Medicinal products comprising a compound of the invention and useful in the treatment of bacterial infections are also disclosed.

A device for filtering the lubricant oil used in vacuum pumps, to be directly installed on the pump, for continuous or discontinuous operation, and characterized in that the filter is of the tangential-flow type.

Multiglazed window (23, 24), heating by a thin conductive layer (25), the window forming an insulation of the parietodynamic type. The conductive layer (25) is transparent and has properties of low emissivity; this brings about a substantial reduction of the heat losses.

Two substantially symmetrical half-slats are joined by an integral flexible joint to form a one-piece articulated slat. Adjacent slats rigidly interlock by cooperation of a projecting rib on one slat and a correspondingly shaped groove on the other slat to form an articulated curtain. The flexible joints are bendable in two directions and coextruded with the half-slats.

The invention relates to an apparatus and process for the direct production of a composite yarn or ribbon of continuous reinforcement fibers and a thermoplastic organic material. The process includes drawing reinforcement fibers from molten glass, driving or extruding a thermoplastic organic material, converging the paths followed by the reinforcement fibers and the organic material toward one ano...
