Inventor: BURDETT SAVILE
IPC: B22C9/06
Filed: 1993-04-30
Abstract: L'invention se rapporte à un procédé de moulage d'un article dans un matériau thermodurcissable. On utilise à cet effet un moule (M1) présentant une cavité de moulage (1a^_) correspondant à la configuration de l'article à mouler, et une cavité réservoir (6, 7) communiquant avec la cavité de moulage (1a^_). Le procédé consiste à introduire le matériau thermodurcissable fondu dans la cavité de moulage (1a^_) et dans la cavité réservoir (6, 7), ce qui permet au matériau coulé dans la cavité de moulage (1a^_) de se refroidir d'abord et de se solidifier au moins partiellement tandis que la chaleur, provenant d'une source extrinséque (8, 9, 9A^_), est appliquée sur le matériau, dans la cavité réservoir (6, 7).

Abstract: A method of severing an elongated flat metal tube (10) of the type including upper and lower flat horizontal walls (10a, 10b), vertical edge walls and vertical partition walls spaced between the edge walls and interconnecting the upper and lower walls to divide the tube into a series of parallel, generally rectangular, longitudinally extending passages. The tube is cut by forming transverse kerfs in the upper and lower walls of the tube and thereafter exerting a relative pulling force on the tube sections on opposite sides of the plane in which the kerfs have been formed to tear apart the remaining tube material at the severing plane and sever the tube. The kerfs are formed in a two-step broaching operation comprising a first cut in which a narrow generally V-shaped narrow angle kerf is formed and a second cut in which the kerf is widened to provide a wide, generally V-shaped, wide angle kerf.

Abstract: Clogging and prolonged down times are avoided in a pelletizer for paste type materials such as sludge by providing an extruder hopper with at least one, preferably two, lower edge slide gates which can be opened to permit movement of a clogged screen zone out of alignment with the discharge opening of the hopper. The clogging material can be scraped off from the screen portion that is taken out of alignment with the hopper discharge opening. The cutting of the extruded sludge is accomplished by an oscillating lower screen section that slides back and forth below the upper screen section. The upper screen section is provided with two, preferably three zones, two of which are perforated and one of which is unperforated to form a closure for the hopper discharge opening. Screeding non-pelletizable material off the screen surface is accomplished either by a separate screeding device or by operating the slide gate or gates as screeds.

Abstract: Bei diesem Verfahren wird der von Metallteilen befreite, vorgereinigte und zerkleinerte Kunststoffabfall in einem Schneckenextruder unter HCl-Abspaltung verdichtet und erhitzt. Die Erhitzung wird solange fortgesetzt, bis eine weitgehende HCl-Abtrennung erfolgt ist und die Viskosität der Kunststoffschmelze bis auf < 300 cSt abgesunken ist. Anschließend wird die Kunststoffschmelze in einem Vergasungsreaktor in einer Flammenreaktion unter Sauerstoffzugabe umgesetzt. Das dabei erzeugte Gas wird gekühlt, entstaubt und entschwefelt. Im Anschluß an die Gasbehandlung kann dieses Gas als Synthesegas in der chemischen Industrie oder zur Energiegewinnung bei der Erzeugung von Strom oder Fernwärme genutzt werden.

Abstract: A multiple charged-particle detector system includes a plurality of charged-particle detector assemblies (10-12) which are each made up of a first arm (19-22) and a second arm (24-27) extending at an angle to each other. Charged particles (4-7) enter an aperture (14-18) at the entrance of the first arm (19-22) of each detector assembly (10-12) and strike a dynode (30-33) positioned at the intersection of the two arms causing electrons to be emitted by the dynode (30-33). Some of the electrons pass into the second arms (24-27) of the detector assemblies (10-12) and are detected by a continuous-dynode electron multiplier (35-38). The first arms (19-22) are narrower than the detectors (35-38), and the detector assemblies (10-12) are arranged in such a way that the minimum separation at which charged-particle beams (4-7) can be detected is determined by the widths of the said first arms (19-22) of the detector assemblies (10-12), and not by the widths of the detectors (35-38) themselves.

Abstract: The present invention relates to improved light devices, such as illumination or signal devices used on vehicles for managing the light reflections from reflective surfaces of such devices. In one exemplary embodiment thereof, a light device includes an array of tubular elements (38) partially embedded in a reflective surface, such as a surface of a lens (40) of said device, which lens focuses, directs or disperses light from the device (30). The use of such an embedded array of tubular elements causes the light source to appear as a substantially opaque surface when the light device is not operative and permits an effective amount of light to be projected from the light device when the device is operative.

Abstract: The invention provides an oral drug delivery composition comprising an  alpha  -adreno receptor blocking drug characterised in that the composition is adapted to release a first portion of the drug in the upper gastrointestinal tract and to release a second portion of the drug by sustained release in the terminal ileum and/or the colon. This composition provides a two phase release profile which maintains sufficient and steady plasma levels for therapeutic effect whilst minimising side effects by avoiding a high peak in plasma levels. The sustained release of the second and optionally the first portion of the drug is achieved by a controlled release system such as a hydrophilic gel matrix. The specific release of the second portion of the drug in the colon can be achieved by coating tablets containing the second portion with a pH or redox sensitive coating such as a polymethylmethacrylate.

Abstract: A wire-cut electrical discharge machine capable of controlling a discharge current to constant. Provided between a main current power source (71) and a capacitor (C) is a current detecting unit (72) which converts electric current (I₃) flowing through a closed circuit formed by the main current power source (71) and the capacitor (C) into voltage to detect the same, and the detected result is transmitted to a control unit (500) after it is smoothed by a smoothing circuit unit (73). Also, electric discharge between a wire (49) and a work (36) is detected by a discharge detecting unit (62). A processing unit (52) of the control unit (500) calculates a sum of the electric current (I₃) per one cycle of electric discharge machining on the basis of the converted voltage value of the electric current (I₃) transmitted through the smoothing circuit unit (73) and the number of electric discharges counted by a counting unit (53). The discharge control unit (55) controls a pulse width of a drive signal (SS) being fed to a main current switches (S2, S3) so that the sum of the electric current (I₃) per one cycle of electric discharge machining amounts to a reference value. Accordingly, an appropriate drive signal (SS) can be output taking into consideration temperature changes during an operational lag time of the main current switches (S2, S3), so that it is possible to readily maintain discharge currents (I 2a,  I 2b ) at desired values.
