Filed: 2001-04-02
Abstract: L'invention peut s'utiliser en tant que base d'éléments en industries mécaniques pour la création d'appareils volumiques parfaitement équilibrés à pistons comportant des chambres multiples (entre 8 et 20 chambres), y compris les appareils à gaz chaud, dans lesquels l'organe de travail fait des mouvements sphériques. Selon l'invention, l'appareil volumique comprend un corps avec des éléments d'appui et un organe de travail, installé dans le corps de manière à pouvoir se déplacer de façon sphérique et muni de cavités méridionales qui forment des chambres de travail conjointement avec les contacteurs (pistons) installés dans ces cavités et montés sur des éléments d'appui. Les contacteurs sont installés de manière à se déplacer de manière azimutale. L'appareil comprend également des éléments d'entraînement du corps de travail et des éléments d'amenée et d'évacuation du corps de travail. Afin de réduire au minimum les forces dynamiques et les pertes mécaniques, les contacteurs sont montés de manière à interagir en permanence avec les éléments d'appui lors du déplacement azimutal des contacteurs. L'invention concerne de différents modes de réalisation des contacteurs. Un mode de réalisation comprend un compresseur avec des soupapes autonomes. Dans un mode de réalisation préféré, les modalités de montage des contacteurs dépendent des fonctionnalités de l'appareil volumique.

Title: Ecran contre le rayonnement destine a des dispositifs radio emetteurs
Inventor: LIBERMAN MARTY
IPC: H01Q1/24
Filed: 2001-01-24
Abstract: L'invention concerne un dispositif de blocage de rayonnement destiné à être utilisé avec un appareil de communication portable tel qu'un téléphone sans fil ou cellulaire. Ce dispositif comprend un écran contre le rayonnement et un connecteur servant à fixer l'écran à l'appareil.

Title: Systeme de frein mecanique sur quatre roues destine a des patins inline
Inventor: LANSEL TOBY
IPC: A63C17/14
Filed: 2003-07-08
Abstract: L'invention concerne un système de frein mécanique destiné à des patins inline et utilisant les quatre roues pour le freinage. L'utilisateur des patins tend la jambe ou les jambes s'il y a des freins sur les deux patins, dans une position réglable prédéterminée pour appliquer le frein, entraînant la tige de déclenchement réglable et à ressort, montée sur le support de cheville pivotant derrière le talon, à pousser le levier du frein s'étendant de derrière le talon sur les deux côtés du cadre vers l'avant où il est fixé de manière articulée afin de se déplacer vers le bas. Au niveau de la moitié du patin, le rail du frein positionné au-dessus des roues et s'étendant sur l'ensemble de la longueur du patin est connecté au levier du frein. Le déplacement vers le bas du levier du frein et du rail du frein entraîne la mise en contact du rail du frein avec les roues, entraînant un frottement et par conséquent un freinage directement proportionnel à la force avec laquelle l'utilisateur des patins tend ses jambes. Le rail du frein est rigide et façonné de manière à s'adapter à la courbe des roues, facilitant ainsi une usure égale des roues aussi bien du point de vue de la forme que du diamètre. Deux supports montés sur le dessous du patin et passant à travers des fentes dans le rail du frein garantissent le centrage du rail du frein. Le ressort de la tige de déclenchement garantit un freinage doux et contrôlable. La tension du ressort de ladite tige est réglable de manière que les utilisateurs des patins de poids différents puissent obtenir une puissance de freinage optimale sans blocage des roues.

Patent CA-2013713-A1 (CA)
Inventor: GURWICZ DAVID
IPC: H05B6/68
Filed: 1990-04-03
Abstract: A magnetron is powered via an output transformer TR whose primary winding (a) is connected in series with a resonant converter oscillator circuit comprising an inductor (L) and a capacitor (C3) and switching transistors (T1, T2) which are connected to positive and negative power supply terminals and are switched by respective current transformers (CT1, CT2).  The switching points of the switching transistors are varied so as to vary the output of the circuit by varying the positive and negative flux excursions in the cores of the transformers (CT1, CT2) such that the net flux excursions are sufficient to saturate the transformers and switch off the switching transistors at a predetermined point in each half cycle.  The relative positive and negative flux excursions in the transformer cores are controlled by providing additional winings (g) which are connected to a control circuit which rectifies the output of these windings and controls the rectified DC voltage appearing across them.
