Patent EP-0507892-A1 (EP)
Inventor: RAPPS PETER
IPC: G10K9/12
Filed: 1991-07-23
Abstract: On propose plusieurs exemples de réalisation pour un transducteur ultrasonore, dans lesquels, par des mesures d'atténuation appropriées, l'angle de propagation du son dans le plan vertical est étroit et large dans le plan horizontal. L'influence sur la caractéristique de propagation est due à la conception, selon l'invention, de la membrane oscillatrice et/ou du boîtier ainsi que par des dispositions multiples d'oscillateurs piézoélectriques. Grâce à ces mesures, l'atténuation des ondes sonores et la sensibilité du capteur sont approximativement de même grandeur sur toute l'étendue de l'angle horizontal jusqu'à presque 180°.

Abstract: PCT No. PCT/SE91/00549 Sec. 371 Date Mar. 22, 1993 Sec. 102(e) Date Mar. 22, 1993 PCT Filed Aug. 21, 1991 PCT Pub. No. WO92/03269 PCT Pub. Date Mar. 5, 1992.A device for processing a concrete layer by water jets, comprising a jet tube on a carriage moveable to and fro along a guide. The jet tube is pivoted in planes substantially parallel to the guide and oscillates in planes making an angle with the guide. The jet tube is inclined in one direction along the extension of the guide during the movement of the carriage along the guide, and a control unit ensures that pivoting of the jet tube with an angular velocity leading to movement of a nozzle of the jet tube along the guide with a velocity substantially equal to the velocity of the carriage is initiated at the same time as the carriage is stopped in an end position, and the control unit starts the movement of the carriage in an opposite direction when the jet tube has finished its pivoting movement.

Abstract: Compositions and methods for using them for hydrolyzing complex carbohydrates into their constitutent monosaccharide units are described. The compositions contain a hydrolyzing acid, an acylating agent and an alkylating agent or water. The method involves utilizing the hydrolyzing acid mixture to reduce native and/or derivatized carbohydrates to their individual monosaccharides and simultaneously acylating the clycosidic bonds of the monosaccharides to protect them against further degradation. The acylated monosaccharides are then deacylated to yield the monosaccharide monomers.

Abstract: 5  A light-tight enclosure for storing and dispensing a roll of photosensitive web material wound about a hollow cylindrical core having open opposite ends. The enclosure comprises a flexible opaque bag with opposite sidewalls extending between opposing rearward and forward portions and opposing upper and lower portions. Each sidewall has a central aperture therein congruent with each core end. The rearward portion defines a closable opening for receiving the roll. A shallow neck portion projects from the forward portion to an end thereof defining an exit slot for dispensing the web material. A collar fits tightly inside each core end, with an annular flange thereon facing axially outward. An annular ring is attachable to each collar in spaced, inward-facing relation to the flange. The roll is first positioned in the bag, through its closable opening, so that the web material extends into the neck portion and out through the exit slot, and so that a central portion of the collar at each core end projects outwardly through the adjacent sidewall aperture, with its flange left inside the sidewall and facing an annular portion thereof surrounding the aperture. The annular ring is then attached to the outwardly projecting portion of the collar in closely spaced, inward-facing relation to the sidewall annular portion, which is thus loosely trapped between the flange and the ring. The bag opening is then closed, and the bag neck portion is folded back and secured against the bag forward portion.

IPC: C03C25/10
Filed: 1992-07-01
Abstract: An optical fibre package suitable for installation using a fibre blowing process comprises at least one optical fibre, an inner coating about said fibre, and an outer resin coating about said inner coating, said resin coating including a significant plurality of particulate inclusions at least 10 µm across, wherein the concentration of the particulate inclusions is significantly greater at the outer surface of the resin coating than at the inner limit of the resin coating. The inclusions may be hollow glass microspheres or mica flakes. The relative absence of significant particulate inclusions at the inner limit of the resin coating improves the mechanical performance of the fibre package relative to similar known packages. The presence of significant inclusions at the outer surface of the resin coating tends, during a blowing process, to increase viscous drag effects and to reduce friction between the package and the duct into which the package is blown, thereby enhancing blowability.

Abstract: A strip imaging wide angle optical system is provided. The optical system is provided with a "virtual" material stop to avoid aberrational effects inherent in vide angle optical systems. The optical system includes a spherical mirror section (12) for receiving light from a 180-degree strip or arc of a target image. Light received by the spherical mirror section is reflected to a frustoconical mirror section (16) for subsequent rereflection to a row of optical fibres (20). Each optical fibre transmits a portion of the received light to a detector (28). The optical system exploits the narrow cone of acceptance associated with optical fibres to substantially eliminate vignetting effects inherent in wide-angle systems. Further, the optical system exploits the narrow cone of acceptance of the optical fibres to substantially limit spherical aberration. The optical system is ideally suited for any application wherein a 180-degree strip image need be detected, and is particularly well adapted for use in hostile environments such as in planetary exploration.
