Title: Resin-mixing article for mine roof anchor
Inventor: WRIGHT RAYMOND L
IPC: E21D20/02
Filed: 1992-07-14
Granted: 1996-07-02
Abstract: An article for assisting in the mixing of components of a resin grouting material within a drill hole in a rock formation to form a hardenable mass anchoring the threaded, distal end of an elongated bolt in the hole.  The article includes an annular base portion having a central, through opening for threaded engagement with the bolt, and at least one leg extending from the base portion in a direction substantially parallel to the axis of the opening.          The article is rotated together with the bolt, the leg having leading and trailing edges with respect to the direction of rotation.   The  leading edge  is a  flat surface substantially parallel to the axis of the bolt and the trailing edge is a relatively sharp, linear edge, non-parallel to the bolt axis.  The article may be employed in chemical anchors with a single leg extending from the base portion toward the distal end of the bolt, or with a pair of legs extending in opposite directions from the base portion.  In another embodiment, the article is employed in a combination chemical-mechanical anchor with the leg extending away from the distal end of the bolt, upon which the mechanical anchor is mounted with the lower end of the shell contacting and supported by the base portion of the article.  Downward force exerted by the shell during expansion strips the threaded  engagement of  the article with the bolt.

Title: Membrane catalyst layer for fuel cells
Inventor: WILSON MAHLON S
IPC: H01M8/10
Filed: 1992-02-18
Granted: 2004-01-13
Abstract: A gas reaction fuel cell incorporates a thin catalyst layer between a solid polymer electrolyte (SPE) membrane arid a porous electrode backing. The catalyst layer is preferably less than about 10 µm in thickness with a carbon supported platinum catalyst loading less than about 0.35 mgPt/cm2. The film is formed as an ink that is spread and cured on a film release blank. The cured film is then transferred to the SPE membrane and hot pressed into the surface to form a catalyst layer having a controlled thickness and catalyst distribution.       Alternatively, the catalyst layer is formed by applying a Na+ form of a perfluorosulfonate ionomer directly to the membrane, drying the film at a high temperature, and then converting the film back to the protonated form of the ionomer. The layer has adequate gas permeability so that cell performance is not affected and has a density and particle distribution effective to optimize proton access to the catalyst and electronic continuity for electron flow from the half-cell reaction occurring at the catalyst.

Granted: 1998-11-10
Abstract: A method and apparatus for storing and producing electrical energy in an electrochemical cell (32), where the cathode is a porous air electrode (7) and the anode is a hydrogen-containing metal hydride (4). According to the invention, an overpressure is allowed to form inside the porous air electrode during charging, the said pressure preventing the formation of hydrogen bubbles on the metal hydride electrode.  The overpressure remains at the desired level because the pores of the air electrode are made so small that the surface tension of the electrolytic solution (6) penetrating into the pores seals the porous air electrode.
