Patent number: 9901867Abstract: The invention relates to an air-separation device comprising a generally cylindrical casing housing a filtration element including a bundle of hollow oblong fibers forming a membrane, the longitudinal axis of the fibers being parallel to the longitudinal axis (A) of the cylindrical casing, said casing comprising an air inlet at a first end and an outlet for purified gas at a second end. The device comprises a member for maintaining the fiber bundle in the casing, characterized in that the maintenance member comprises at least one spring member disposed inside the casing, said spring member being loaded between an end-stop formed by the casing and a longitudinal end of the fiber bundle in order to maintain the fiber bundle longitudinally in place while allowing it to dilate and contract.Type: GrantFiled: September 15, 2014Date of Patent: February 27, 2018Assignee: L'AIR LIQUIDE SOCIETE ANONYME POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDEInventors: Xavier Roussin-Bouchard, Aurelie Caillaud, Pierre Gianese, Elodie Dumont, Jean-Marc Dejonghe

Publication number: 20070006677Abstract: The invention relates to a control handle for a public works vehicle, comprising a core having an inner cavity. According to the invention, control elements are mounted to said core, said elements comprising buttons and/or sliding members which are intended to be actuated by an operator in order to enable the different functions of the vehicle to be controlled. In addition, at least part of the surface of the aforementioned core is covered with a casing comprising one layer of at least one low-pressure-cast thermosetting polymer foam.Type: ApplicationFiled: October 6, 2004Publication date: January 11, 2007Applicant: BOSCH REXROTH D.S.I.Inventor: Xavier Roussin-Bouchard
