Title: Fuel Cells Mounting Concept
Inventor: VICTOR RAUE
IPC: H01M8/247
Filed: 2020-11-17
Granted: 2022-07-01
Abstract: The invention provides a truck or tractor semi-trailer combination interconnected via a fifth Wheel, with a chassis formed by at least two elongate beams along a length of the truck. The chassis forms a suspension mount for a suspension system that connects to an unsprung mass including an axle and (drive) wheels, which has a primary eigenfrequency mode (also called wheel hop mode) impacting the chassis. The at least two elongate beams are coupled by at least a cross beam extending laterally along the truck. The cross beam forms at least one mounting position for a first fuel cell mount, said chassis further comprising a second fuel cell mount. First and second fuel cell mounts are arranged to carry a fuel cell module having elastic connectors provided at the side walls, to connect to said first and second fuel cell mounts respectively. In this manner the fuel cell module is elastically suspended to the chassis with a heave, pitch and roll eigenfrequency that is tuned to be distinct of the primary eigenfrequency of the unsprung axle mass by providing the elastic connectors with an axial stiffness, in the direction of gravity, that is substantially lower than a lateral and/or longitudinal stiffness.

Title: Systeme et procede de traitement local d'eau
Inventor: PLESTER GEORGE
IPC: C02F9/00
Filed: 2000-08-04
Abstract: L'invention concerne un procédé de traitement d'eau utilisant une cartouche (2) démontable et amovible à structure interne maillée. Un réchauffeur (6) jetable chauffe l'eau qui alimente la cartouche (2). Les solides précipités sont recueillis sur la surface maillée à condition que la température et le temps de séjour soient maintenus de façon appropriée. La chaleur réduit sensiblement la dureté de l'eau imputable aux bicarbonates, déposant les carbonates sur la surface maillée, après quoi les métaux lourds viennent se codéposer sous l'effet du changement de pH résultant. La cartouche (2) comporte un vide (11) recueillant les gaz entraînés tels que les composés organiques volatiles, le chlore et l'air. La stérilité de l'eau est obtenue par chauffage de l'eau durant une période de temps appropriée. La turbidité de l'eau est supprimée par décantation en raison de la moindre vitesse de l'eau dans la cartouche (2), laquelle vitesse est commandée par régulateur et un filtre situé à la sortie de la cartouche (2). Le filtre se bloque lorsque la cartouche (2) est saturée en bicarbonate, ce qui oblige l'utilisateur à remplacer la cartouche (2) utilisée. Un échangeur de chaleur (18) assure une économie de chauffage et une sortie d'eau fraîche traitée. L'eau de la cartouche (2) circule à travers un réfrigérant intermédiaire et l'échangeur de chaleur (18) puis arrive dans un réservoir de stockage (26). L'eau du réservoir de stockage (26) est gardée à l'abri de l'air par une limite étanche mobile. Finalement, l'eau du réservoir de stockage (26), acheminée vers un distributeur (50), convient ensuite pour un distributeur de boissons à mélangeur de sortie. Un écran de visualisation indique l'état du système de traitement de l'eau.
