Patent EP-0325595-A1 (EP)
Inventor: BLANDING DOUGLASS LANE
IPC: G03B27/58
Filed: 1987-08-17
Abstract: Le mécanisme décrit sert à maintenir une bande mobile (2) de matériaux en feuilles dans sa bonne direction le long d'un guide-lisière (10) dans un appareil tel qu'une tireuse photographique. Un cylindre souple (12) est monté sur un arbre de cylindre (14) qui pivote à chacune de ses extrémités (16) autour d'un organe de liaison (18) pivotant à son tour par rapport à une structure fixe (8). L'organe de liaison articulé (16, 18) permet au cylindre (12) de trouver sa position naturelle stable en roulant sur la bande mobile (2), de sorte que son axe, c'est-à-dire l'arbre de cylindre (14), soit sensiblement perpendiculaire à la direction d'avance (5) de la bande (2). Un ressort de tension (24) placé entre la structure (8) et l'organe de liaison (18) sollicite le cylindre (12) et la bande (2) pour que celle-ci occupe sa position désirée le long du guide-lisière (10).

Abstract: Le procédé décrit sert à produire des filtres, dont la partie de filtrage active est constituée d'une bande de matériau de filtre pliée, telle que de préférence du papier qui est délimité pendant le procédé par des bords latéraux au niveau desquels se terminent les plis et par des bords terminaux au niveau desquels se situe le premier ou le dernier pli, de façon à former des unités de filtre (49). Celles-ci sont produites par un procédé automatisé, dans lequel la bande de matériau de filtre est plissée et pressée de façon à former les plis. Les espacements entre les plis sont maintenus constants au moyen d'un élément à vis pourvu de filetages exerçant une pression vers le bas entre les plis et formant des éléments d'espacement entre lesdits plis. L'élément à vis tourne durant l'avancement de la bande pliée. Des rubans enduits de colle sont pressés sur les bords latéraux de la bande, de façon à recouvrir les extrémités des plis. L'ébauche, qui est ainsi continuellement produite et qui comprend la bande de matériau pliée et les rubans collés sur ses bords latéraux, est découpée de façon à former les unités de filtre (49). Plusieurs unités de filtre (49) sont ainsi assemblées dans un logement (69), de façon à former un filtre dont la surface de filtrage correspond à la surface combinée des unités qu'il comprend.

Abstract: A method for determining blood groups by the solid-phase method using blood group-specific antibodies and a carrier to whose surface the antibodies can be irreversibly bound is obtained by a solution of an antibody of the IgM type
 (a) either being contacted with the carrier surface simultaneously with the erythrocyte suspension to be determined or
 (b) the antibodies first being dried as reagent reservoir on the carrier surface and being dissolved, and thus contacted with the carrier surface, only by the addition of the erythrocyte suspension when the assay is carried out,
 and the determination being carried out a short time after the contacting, it being necessary that the antibody concentration is no higher than required to form an irreversible or immobilised layer of antibody molecules on the carrier surface, which layer is able specifically to bind erythrocytes, and is insufficient to bring about an agglutination reaction.

Date May 5, 1989.Device permitting localization of the emergence point of ventricular tachycardias in cardiological medicine, characterized, in comparison with traditional cardiac mapping, by: a precision of the same order, its speed of use, its low cost and the further possibility of localizing the macro-re-entry pathway (around aneurysms, for example). In distinction to traditional mapping, this device dispenses with the construction of a map of isochrones (14). The principle of the device according to the invention is based on localization of the propagation of the myocardial cell depolarization, or of the muscle contraction of the heart (15) which results directly therefrom. This localization is carried out in stages (17) over the length of its pathway (13) from an arbitrary point (16) on the heart chosen by the operator, retracing this pathway as far as its source (12'), which is referred to as the emergence point.

Abstract: A piston/cylinder unit (1, 4) as a supply unit, which can be actuated by a drive device (7), for the respiratory gas in the respiratory circuit of a respirator, in which the piston (4) is sealed in relation to the cylinder (1) by a mutually symmetrically arranged roller diaphragm pair (8, 9) which divides the cylinder content into a pre-chamber (18) and a working chamber (20), is to be improved in such a manner that the wear of the roller diaphragms (8, 9) during the working strokes and in particular at the start is reduced by accurate unrolling of the folds, and a tightness control even during operation and immediate recognition of leaks caused by bending stress, ageing or other influences are made possible. To this end it is envisaged that the inner space (15) enclosed by the roller diaphragms (8,9) together is kept at an internal pressure which deviates from the pressure both in the pre-chamber (18) and in the working chamber (20) in such a manner that the higher of the pressures occurs on the concave inner sides of the folds (13, 14).

Abstract: The present invention entails a process for treating wastewater utilising a return activated sludge process. Primary sludge is separated from the wastewater stream and conveyed into a fermentation tank and held a sufficient time to permit hydrolysis of suspended solids so as to produce soluble substrates. The soluble substrates are mixed with the return activated sludge and held for a selected time period to form conditioned return activated sludge. Thereafter, the conditioned return activated sludge is mixed in an initial aerobic treatment zone with pretreated wastewater. Therefore, the mixed conditioned return activated sludge and pretreated wastewater is conveyed through a series of treatment zones, which may include at least one anoxic treatment zone, where phosphorus and other pollutants are removed from the wastewater.
