Title: Dispositif de filtration et dispositif de tamisage
Inventor: HORTON DAVID ROBERT
IPC: B01D65/08
Filed: 1999-04-01
Abstract: L'invention concerne un dispositif de filtration (10) comprenant un élément filtre (12), un élément de déviation (14), et une série de nervures de déflexion (16A-16D). L'élément filtre (12) de ce dispositif est fabriqué à partir d'un substrat céramique présentant une porosité et une densité homogènes. L'élément de déviation (14) est constitué de plusieurs éléments de déviation allongés (18A-18E), qui définissent chacun un canal longitudinal (20A-20E), la section transversale de ces éléments de déviation (18) formant par ailleurs un C avec chaque canal (20) généralement aligné par rapport au sens d'écoulement de fluide à l'intérieur du dispositif de filtration (10). Les éléments de déviation en forme de C (18), qui sont incorporés au substrat filtrant céramique (12), sont en outre fabriqués dans un matériau relativement non poreux. Les nervures de déviation (16A-16D) sont placées sur un espace défini entre des éléments de déviations adjacents (18), et fixées sur la surface supérieure dudit substrat (12), chacune de ces nervures (16) faisant saillie sur une distance prédéterminée depuis lesdits éléments de déviations adjacents (18), de manière à former un orifice que peut traverser un courant de fluide pendant le processus de filtration. L'élément de déviation (14) du dispositif de cette invention est en outre conçu pour dévier une partie du fluide traversant ledit élément filtre (12), de manière à réorienter cette partie vers la surface supérieure du substrat. Cet écoulement inverse de fluide à travers l'élément filtre permet en effet de réduire la rétention de particules, et en particulier l'accumulation d'un 'film biologique' sur ledit élément filtre ou à l'intérieur de celui-ci.

Title: Electrical power conversion circuit
Inventor: PETERSON WILLIAM A
IPC: H02M3/158
Filed: 1990-09-14
Abstract: ELECTRICAL POWER CONVERSION CIRCUIT                ABSTRACT OF THE DISCLOSURE    An electrical power conversion circuit having a readily varied conversion ratio and accommodating bidirectional energy flows is disclosed.  The converter employs a series connected and a shunt connected semiconductor switch which may be either unidirectional or bidirectional (depending upon whether AC/DC or DC only operation is sought)  and an inductor.   The switches are insulated gate voltage controlled devices with charge storing capacity present at the gate.  The switches are operated from a variable duty cycle rect-angular pulse which is differentiated at the leading and trailing edges to form two pairs of oppositely sensed short duration pulses.  The two pairs of short duration pulses are then coupled by a transformer having two matched but oppositely sensed secondaries to the gate circuits of the two semiconductor switches.  A          Zener diode in each gate circuit preserves the charge stored at each gate resulting from the first positive pulse of the pair, and allows the semiconductor gate capacity to discharge as the following negative pulse appears.  The circuit thus reconstitutes the original rectangular waveform in two mutually inverted forms at the gates of the two semiconductor switches to achieve the required alternate switching states with high accuracy and with a minimum of components.    The AC/DC or DC only circuit is reduced in size and weight by a factor of 10  from that of a conventional AC only adjustable autotransformer.
