Patent number: 10471244Abstract: A liquid applicator comprising an absorbent member, and a single-piece, unitary body. The body can include a closed container defining a reservoir, and a tab. The container can include a main portion, a transition portion, a rib, and a chamber located in the tab and coupled to the transition portion via a frangible connection. The main portion, the transition portion, the rib, and the chamber can each define a portion of the reservoir, and at least the main portion, the transition portion, and the rib can have a uniform wall thickness. The tab can include the chamber and can be coupled to the transition portion at least by the frangible connection, the tab being movable with respect to the transition portion between a first position in which the frangible connection is intact and a second position in which the frangible connection is fractured.Type: GrantFiled: October 9, 2015Date of Patent: November 12, 2019Assignee: 3M Innovative Properties CompanyInventors: Alan R. Dombrowski, Stephane Levesque

Publication number: 20110281193Abstract: Disclosed herein is a fuel cell having a catalyst coated membrane (CCM) including a membrane sandwiched between an anode layer and a cathode layer; two gas diffusion layers located against respective anode and cathode layers; and two separator plates located against the respective gas diffusion layers. The fuel cell has at least one hydrogen passageway for hydrogen fuel, which extends through the CCM and disposed orthogonal relative to the plane of the layers. The hydrogen fuel is blocked from contacting the cathode layer so that the hydrogen fuel is provided to one side of the anode layer. At least one air/oxygen passageway for air/oxygen fuel extends through the CCM and disposed orthogonal relative to the plane of the layers. The air/oxygen fuel is blocked from contacting the anode layer so that the air/oxygen fuel is provided to one side of the cathode layer. A coolant pathway is in fluid communication with the layers and located to remove heat away from the layers during operation of the fuel cell.Type: ApplicationFiled: May 20, 2011Publication date: November 17, 2011Applicant: EnergyOr Technologies Inc.Inventors: Stéphane Lévesque, Raymond Roberge

Publication number: 20080076005Abstract: The dominant fuel cell design is based on using separator plates with flow fields to distribute the reaction gases parallel to the membrane. In our invention the solid electrolyte membrane fuel cell has a multitude of conduits that penetrate the catalyst coated membranes and the porous gas diffusion layers in a perpendicular direction, each conduit separated by an active area. The conduits are distributed in a repeatable parallelogram unit to create a two dimensional pattern. The conduits have appropriately positioned integrated gaskets to provide reactant gases to the anode (fuel) or cathode (oxidant) and to ensure that the anode fuel is prevented from entering the cathode side of the membrane and vice-versa. A separate conduit (in/out) for the water cooling can be added or the water cooling can be integrated to the air exhaust or the hydrogen exhaust to extract the heat from the electrochemical reaction and the reaction water.Type: ApplicationFiled: September 22, 2006Publication date: March 27, 2008Inventors: Stephane Levesque, Raymond Roberge

Publication number: 20050287320Abstract: A variety of hollow structures with unique morphologies were manufactured with a rotational spinning technique. Phase separation of soluble solutions or emulsions was induced within a filled mold as it was being rotated about one of its axis. The density difference between phases results in sediment at the inner lumen of the mold under centrifugal forces. After or during sedimentation, gelation of the phase-separated particles fixes the hollow structure morphology and the solvent remains in the center of the mold. The solvent is removed from the mold resulting in a coating or tube. By controlling the rotational speed and the formulation chemistry, the tube dimensions and wall morphology can be manipulated. This technique offers a new approach to the manufacture of polymeric tubes. It requires small quantities of starting material, permits multi-layering of tubes, is applicable to diverse polymers and can result in highly diffusive hollow structures while maintaining good mechanical strength.Type: ApplicationFiled: August 18, 2005Publication date: December 29, 2005Applicant: matRegen Corp.Inventors: Paul Dalton, Molly Shoichet, Stephane Levesque
