Abstract: L'invention concerne un dispositif destiné à recueillir et à séparer des copeaux et du liquide tombant de machines-outils. Le liquide de refroidissement est recyclé pour une réutilisation et les copeaux sont évacués. Ce dispositif comprend un réservoir (1) destiné à recevoir les copeaux et le liquide de refroidissement, ce réservoir (1) étant prolongé d'une section de guidage (3) ascendante prolongée, à son tour, d'une section de déchargement (4) élargie. Un élément de transport fermé de type chaîne est guidé au moins dans la zone recevant les copeaux et le liquide de refroidissement ainsi que dans la section de déchargement (4) par des éléments de renvoi (6, 7) dont un au moins est couplé au servomoteur. Enfin, un tambour filtrant monté rotatif (12) est en liaison d'entraînement avec l'élément de transport. L'invention vise à proposer une solution qui, avec un tel dispositif, permette de réduire la charge sur le palier du tambour filtrant et, malgré un élément de transport tournant en continu, la formation sur la circonférence extérieure du tambour d'un gâteau de filtre qui agisse positivement sur l'efficacité du filtrage. A cet effet, l'élément de transport est guidé à une distance radiale du tambour filtrant (12) le long de rails de guidage (13) du tambour filtrant (12). L'élément de transport et le tambour filtrant (12) présentent, seulement dans le sens circonférentiel, des éléments entraîneurs qui coopèrent en étant placés respectivement à une certaine distance les uns des autres et qui agissent sur le tambour filtrant (12).

Granted: 2010-11-16
Abstract: A process for production of a monolithic article from a web of fibres of oriented polypropylene homopolymer or copolymer having a weight average molecular weight (Mw) of at least 250,000 includes the steps of subjecting the web to elevated temperature and pressure sufficient to melt a proportion of the polymer and compact it, and thereby yielding an oriented phase and a matrix phase, and effecting a heat treatment selected from (i) subjecting the compacted web to a retarded rate of cooling down to a lower temperature at or below the temperature a which the recrystallisation of the matrix is complete;  and (ii) annealing the compacted web at an annealing temperature within 15 ~C  of the temperature at which the matrix phase is completely melted. The resultant articles have good stiffness and strength, and acceptable ductility, yet corresponding articles made with polypropylene of lower Mw are brittle.

Granted: 2012-06-12
Abstract: A DVD authoring system in a processor-based system removes an author from consideration of the DVD Specification during authoring. According to a preferred embodiment, the authoring system provides an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-form PGC layout structure comprising control PGC abstractions and router PGC abstractions. The compiler then resolves the PGC abstractions according to source-target connections. During playback on a DVD player, the PGC abstractions form elements in a connection-switching abstraction superstructure. Accordingly, in response to DVD-consumer and other control events, a source PGC preferably determines target PGC information and then transfers control, via virtual connections through necessary router PGC abstractions, to a target PGC abstraction. The target PGC abstraction then correspondingly initiates playback of a movie chapter or displays a menu.
