Patent WO-02090773-A1 (WO)
Title: Compresseur lineaire
Inventor: PUFF RINALDO
IPC: F04B35/04
Filed: 2002-05-07
Abstract: L'invention concerne un compresseur linéaire comportant un cylindre (2) et un piston (1) mus par un moteur linéaire électrique (4, 5, 6) comportant un ou plusieurs éléments souples (30, 50) constitués de fil d'acier comportant une partie de volute centrale (30a, 50a). Une jambe (30b, 30c, 50b, 50c) s'étend depuis chaque extrémité de la partie de volute centrale (30a, 50a). Dans un premier mode de réalisation, l'une des jambes (30b) est fixée de manière interne au piston (1), et l'autre jambe (30c) à une partie du cylindre (2). Dans un second mode de réalisation, la partie de volute centrale (50a) est montée directement sur le piston (1), et les deux jambes (50b, 50c) sont connectées fixement au cylindre (2). Lorsque le piston est mu par l'action du moteur linéaire électrique, le fil de la partie de volute centrale de l'élément souple se déforme et s'étire dans la direction de la course du piston. De préférence, plusieurs éléments souples sont montés sur le piston (1), de sorte à ce que les parties analogues de la partie de volute centrale soient espacées de manière angulaire. Une telle disposition permet une distribution plus équitable des forces du piston agissant contre les parties de volute centrale des éléments souples.

Abstract: L'invention concerne un composant (20, 22) ainsi qu'un procédé destinés à un processus de coulage, généralement de coulage à froid de murs, planchers, plafonds ou autres panneaux de béton ou éléments réalisés sur place, dans la construction de bâtiments, ce procédé consistant à laisser encastrée, dans le panneau coulé, une surface de fixation (24) pouvant se régler de manière à permettre la correction de surfaces coulées non uniformes. Ce composant peut s'incorporer à des systèmes classiques de fixation de formes, lesquels mettent en oeuvre des attaches servant à espacer des formes amovibles/réutilisables en maintenant ces formes à une certaine distance l'une de l'autre, et il peut également retenir un matériau barrière (généralement une isolation en mousse expansée) contre la surface intérieure d'une forme (des formes) pendant le processus de coulage; quand les formes sont enlevées, elles laissent le composant encastré, celui-ci constituant une surface réglable conçue pour la fixation d'un matériau tel qu'un matériau de finissage en feuille. Ce composant permet le réglage de sa surface de montage, dans le panneau, par rapport à la surface de coulage et par rapport à d'autres composants analogues, de manière à offrir une surface (sensiblement) uniforme destinée au montage de matériaux de finissage et/ou d'éléments fixes.

Title: Time synchronization of control networks
Inventor: OLSON GENE H
IPC: H04L12/28
Filed: 1990-02-23
Abstract: TIME SYNCHRONIZATION OF CONTROL NETWORKS        ABSTRACT OF THE DISCLOSURE A distributed computer network is synchronized as to time provided to each peerway and its associated stations or nodes.   Highway interface adapters (HIAs) serve as time references for each node on a peerway and as communication links between peerways.   At periodic intervals, each HIA transmits a Time Interval Control packet (TIC)  including the time of day and an ordinal number denoting the HIA priority in the network and a distance factor.  By comparing ordinal numbers, an HIA will adjust its clock to the TIC packet being transmitted from the HIA with the highest priority and the smallest distance.   This ensures that a synchronized time is provided to each node on the network from a single source over an optimal distance.

Title: Variable gain distributed amplifier
Inventor: HELMS DAVID R
IPC: H03F3/60
Filed: 1990-08-16
Abstract: VARIABLE GAIN DISTRIBUTED AMPLIFIER                ABSTRACT OF THE DISCLOSURE    The invention relates to a variable gain distributed amplifier for use at microwave frequencies, and fabricated in a monolithic microwave integrated circuit format.  In the amplifier, the attenuation is varied, based upon digital control of a dual gate segmented FET.   The amplifier has a nearly flat insertion phase and amplitude response,  and an insertion phase response that varies only slightly between gain settings.  The amplifier employs segmented dual gate field effect transistors as the gain elements, having their signal input and signal output electrodes which provide shunt capacities (CG1s, CDs) interconnected with serial inductances to form separate low pass transmission lines having relatively high cut-off frequencies.  The amplifier has means to insure stability and uses Chebyshef equal ripple techniques to linearize the amplitude and insertion phase response.
