Patent EP-0401333-A1 (EP)
Inventor: GUMPERT HORST J
IPC: B62D47/02
Filed: 1989-12-20
Abstract: Véhicule à éléments multiples, notamment autobus articulé présentant une liaison articulée comportant une couronne de pivotement entre deux éléments (21, 22) du véhicule. Les éléments du véhicule sont liés entre eux le long de l'axe longitudinal, tout en étant essentiellement solidarisés en torsion. Dans le cas d'inégalités de terrain, des contraintes élevées de torsion devront donc être transmises par l'intermédiaire de la couronne de pivotement. Alors que dans les couronnes de pivotement traditionnelles, les cercles (1, 3) formant la couronne sont stabilisés vis-à-vis de ces contraintes en les assemblant au moyen d'entretoises, il est prévu, selon l'invention, d'agencer le cercle extérieur (1) de la couronne de pivotement en le dotant d'une rigidité suffisante pour qu'il forme lui-même ces entretoises. On diminue de cette façon la hauteur de la structure, tout en simplifiant la construction.
Patent EP-0411079-A1 (EP)
Title: Method for the deposition of at least one thickness of at least one decorative material to an object, and decorative object obtained by such method.
Inventor: MIREMAD BAHMAN
IPC: C23C14/16
Filed: 1990-02-12
Abstract: The method which is particularly convenient for depositing a layer of noble metal such as gold alloy to a ceramic resistant layer deposited as a base layer to a decorative object, is particularly convenient in that the deposition of the base layer and the surface coating are carried out in the same vacuum housing by means of at least two vacuum deposition devices mounted in said housing. This arrangement avoids any manipulation and changing of the device and allows to apply the deposition by using simultaneously or alternatingly the various vacuum deposition devices.

Abstract: L'invention décrit une tête mélangeuse pour le moussage d'un produit avec un gaz, par exemple un produit laitier avec l'azote. La tête mélangeuse présente un rotor à couronnes dentées coaxiales disposées alternativement radialement et axialement. De ce fait, le produit à faire mousser traverse la tête mélangeuse en partie radialement et axialement, la denture des couronnes dentées montées les unes derrière les autres dans le sens axial pouvant s'affiner au fur et à mesure qu'elle se rapproche de l'ouverture de sortie. La tête mélangeuse est, de préférence, conçue en plusieurs étages, c'est-à-dire qu'à l'intérieur d'un étage rotor/stator, les couronnes dentées ont la même position axiale sans déport axial.

Abstract: A method and an apparatus for specifying slice planes in an X-ray CT, capable of specifying a slice plane corresponding to the desired tomographic image easily and accurately. In the apparatus, scans of the body to be examined are carried out and the projection data are stored in the large capacity memory (11) first. Then, a scanogram of the body to be examined is displayed, on which a cursor (21,31,41) is controlled in order to specify the desired slice planes corresponding to the desired tomographic images to be reconstructed. Then, the desired tomographic images are reconstructed for the desired slice planes indicated by the cursor by using an appropriate part of the projection data stored in the memory (11) which corresponds to the desired slice planes indicated by the cursor (21,31,41). Either one of the helical scan and the multi-scan can be used for collecting the data to obtain the scanogram and the tomographic images (23,33).

Abstract: Fonts for use in printing documents are dynamically generated as they are required for printing. Preferably only those characters from the font which have been used in the document are dynamically generated in bitmap form and sent to the printer prior to data for identifying and positioning the characters on the page. The dynamically generated bitmaps may be retained by the printer for use in printing subsequent pages and documents. Less data per page needs to be sent to the printer and the sending of full-page bitmaps may be avoided.
Patent EP-0472340-A1 (EP)
Inventor: HAYWARD WESLEY H
IPC: H03F3/45
Filed: 1991-08-12
Abstract: A compensation method and apparatus for enhancing single-ended to differential conversion includes a compensation network that is coupled between the single-ended voltage input and the bias terminal of a differential stage. The compensation network has an impedance substantially equal to the impedance presented by the bias circuit used to bias the differential stage. Accordingly, the compensation network provides a current that substantially cancels the signal tail current supplied to the bias terminal of the differential stage, resulting in a balanced differential output. The compensation network may be AC coupled from the single-ended voltage input to the bias terminal in order to preserve the original DC operating condition. The compensation network may be chosen to provide more cancelling current at higher operating frequencies. Additionally, the compensation network can be configured to match a bias circuit built from resistors, transistors, current mirrors, or the like.

Abstract: A method and apparatus for treatment of relatively moving substrate materials and the novel products produced thereby created by precise application of high temperature pressurized streams of fluid against the surface of the materials to melt and remove material which imparts a recessed channel to the materials that facilitates separation of the materials. The apparatus includes an elongate manifold for receiving heated pressurized fluid, such as air, disposed across the width of the relatively moving material and having a single slit the full width of the substrate for directing the fluid into the surface of the material. The substrate material is treated with an acrylic resin to eliminate jagged or frayed edges either prior to or after the melting and removal process by means of the high temperature pressurized fluid streams.

Abstract: A method of obtaining monosialoganglioside (GM1) from an aqueous solution containing a mixture of gangliosides, involves incubating the solution at a pH of from 5 to 6.5 in the presence of an neuroaminidase so as to hydrolyse di-, tri- and tetra- sialogangliosides therein to enrich the GM1 content of the mixture. The resultant solution is dried, the residue re-dissolved in a mixture of chloroform, methanol and water and is then subjected to exclusion chromatography. The appropriate fractions are collected and lyophilized.

Abstract: Disclosed is a method and apparatus for braking a selected group of rollers in a live roller conveyor in which groups of rollers (2) are driven by belts (7) looped about a torque tube (6) carried for rotation about a drive shaft (5) and maintained in frictional contact therewith by the tension in the said belts. The brake means comprises a member (8) carried on a pivotally mounted cam (11) and moveable between an "on" position in which the member (8) is in contact with and applies pressure to the torque tube (6) and an "off" position out of contact with the torque tube. In the "on" position the member (8) applies pressure to the torque (6) along a line radially of the drive shaft (5) that causes the tube (6) to move into a position in which it is coaxially aligned with the drive shaft (5) whereby the frictional drive between the torque tube (6) and the drive shaft (5) is disengaged thereby bringing the rollers (2) associated with the torque tube (6) to a halt. The cam (11) is caused to move the said member (8) between the "on" and "off" positions by a pneumatic motor (20) actuated by sensor means downstream of the group of rollers (2) indicating the accumulation of packages at the sensor.

Abstract: The control of a stirrer is carried out by means of a drive shaft in two parts (24, 26) connected by a magnetic coupling (28). A leakproof casing (48) is placed between the two parts (30, 34) of this coupling and carries the driven part (26) of the drive shaft by means of a smooth bearing (66). The lubrication of this bearing is ensured by the liquid mixture to be stirred, by virtue of a helical groove (68) formed on the driven part. The assembly is demountable and comprises a first subassembly comprising in particular the motor and the driving part (24) of the shaft, and a second subassembly comprising in particular the driven part (26) of the shaft, the stirrer and the leakproof casing. The latter is mounted in a leakproof manner, using merely gravity, on a vessel containing the stirrer. <IMAGE>
