Patent EP-0324287-A1 (EP)
Inventor: CARRUTHERS ALEC REGINALD
IPC: E03F3/06
Filed: 1988-12-30
Abstract: The burster has a body in two parts (10, 12)  separable by pistons (20,22,­24) in cylinders (14, 16, 18) in the part (12). The pistons have piston rods (32, 34, 36) secured to the part (10) by screws (54). The relative rectilinear movement of the parts (10, 12) is guided by the sliding engagement between the internal cylindrical surfaces (58, 60, 62) of the rings (44) and (46) and of the cylinder (18) and the external surfaces of the piston rods (32, 34,­36). Separating movement is effected by fluid fed into the three cylinders via a passage (88) and is limited by engagement between stop surfaces (66, 68) on the part (10) and stop surfaces on the part (12). Approach movement is effected by fluid fed into two cylinders (14, 16) via a passage (90) and is limited by engagement between the inner surface (64) of the part (10) and the rings (44, 46).

Abstract: The invention relates to a method making it possible to etch, with good manufacturing efficiency, a diffraction grating on a semiconductor material, in particular in order to construct a distributed grating on a guide structure. It consists in succession in:
 - depositing, by epitaxy, on a substrate (S), an optical confinement layer (11) consisting of a first semiconductor material;
 - depositing, by epitaxy, an active layer (12) consisting of a second semiconductor material;
 - depositing, by epitaxy, a barrier layer (13) consisting of a third semiconductor material;
 - depositing, by epitaxy, a guide layer (14) consisting of a fourth semiconductor material;
 - depositing a layer of photosensitive resin, and cutting it according to a shape to be given to the diffraction grating which is to be produced;
 - etching the guide layer (14) by means of a selective chemical agent which does not attack the material of the barrier layer (13), or the resin, leaving it to act until the entire thickness of the guide layer (14) has been traversed, this thickness being chosen equal to the depth desired for the diffraction grating.

Abstract: Diluent and wash compositions are useful in a rapid and sensitive assay for detecting antibodies, and especially retroviral antibodies, in a biological specimen. The diluent composition is buffered to a pH of 6 to 10 and includes a protein or carbohydrate, a surfactant and a negatively-charged organic compound. The wash composition is buffered to a pH of 5 to 10 and includes a surfactant. These compositions can be included in a diagnostic kit. The method of this invention includes mixing the biological specimen with the diluent composition, forming an immunological complex between ligand and antibodies in the specimen and separating complexed materials from uncomplexed materials using a filtration membrane and a washing step. An enzyme labeled anti-antibody is added to form a ligand-antibody-antibody complex followed by its detection using suitable reagents.

Abstract: The plug for the medullary canal is formed by a stopper consisting of randomly packed, helically curled filaments of a resorbable, polymeric material, such as, for example, a polylactic acid. A stopper of this type can, as a result of its elasticity, adapt very satisfactorily to the contours of the medullary cavity, and also even when it is pushed forwards beyond the narrowest point. In addition, it has a selective blocking effect, i.e. it holds back viscous substances such as the bone cement, but is permeable to air and thin liquids such as rinsing water and blood, so that such media can be displaced from the plastic bone cement, as a result of which the quality of the solid cement is improved.

Abstract: Le procédé décrit, qui sert à fabriquer un matériau polymère poreux, consiste à chauffer un mélange constitué d'un polymère thermoplastique et d'un agent tensioactif cationique ou non ionique ayant un équilibre hydrophile-lipophile compris entre 4,0 et 6,0, à une température et pour une durée suffisantes pour permettre la dissolution mutuelle du polymère et de l'agent tensio-actif. Le mélange est ensuite refroidi à une température telle qu'il se produit une séparation de phase liquide-liquide en état de non-équilibre, laquelle entraîne la formation d'une matrice bi-continue du polymère et de l'agent tensio-actif, de sorte que ceux-ci forment deux phases séparées entremêlées de grande superficie interfaciale. L'agent tensio-actif est ensuite extrait du polymère. Le matériau polymère poreux produit par le procédé décrit ci-dessus présente une structure filamenteuse ou en dentelle composée de plusieurs torons polymères reliés entre eux en des points espacés le long de chaque toron.

Abstract: A method and apparatus provide for the effective centrifugal washing and/or thickening of paper pulp, using a perforated cylinder (12) . A stock head box (14), located within the cylinder, applies a thin sheet of pulp (15) directly on the interior the cylinder, at a high rate (e.g. about 20 meters per second), at a first arcuate position (30). The cylinder is rotated at high speed (e.g. 100 rpm, to provide an acceleration on the order of about 10 gs), whereby centrifugal force causes liquid in the pulp to move radially outwardly through the openings in the screen cylinder. The pulp is withdrawn from the interior of the cylinder by a vacuum roll (22) or the like at a second arcuate position (31) less than 360° from the first position. The withdrawn pulp is moved by a screw conveyor (24) or the like away from the cylinder in a dimension generally parallel to the axis of rotation (20), and the withdrawn liquid passes through channels in a drum (38) surrounding the perforated cylinder, and is engaged by an impeller (42), and flows to.a volute (26) for removal. Wash water may be added by a wash water head box (28) within the cylinder between the first and second arcuate positions (at 34). A drive roll (18) operatively engages the exterior of the cylinder for effecting rotation.
