Granted: 1992-08-11
Abstract: METAL AND METAL OXIDE CATALYZED ELECTRODES FOR ELECTROCHEMICAL CELLS, AND METHODS OF MAKING SAME            ABSTRACT OF THE DISCLOSURE Porous electrodes for use in fuel cells and other electrochemical cells are disclosed.  Principally, the electrode  is intended for use  as a cathode of a fuel cell, having a catalytically  active layer  on  a  porous conductive  substrate,  which  catalytically active layer is derived from non-noble metals. The loading of the catalytically  active  layer  is  lower in  terms  of  weight  of catalyst  per  unit area of geometrical  electrode  surface  than heretofore,  and  the operating characteristics of the  electrode compare  favourably with prior art electrodes having noble  metal catalysts,   at  considerably  lower  cost.  Several  alternative methods   of   forming  the  electrode  are   taught,   including impregnating  a  porous conductive substrate with  a  metal  salt solution, followed by chemical or thermal formation of the porous catalytically   active layer;  or mixing the catalytically active material  with the material of the porous conductive  substrate, followed by fabrication of the electrode; or depositing pyrolitic carbon from the gas phase onto a porous conductive substrate,  at elevated  temperatures  in a gas atmosphere.  The  electrode  may comprise a porous metallic current collector,  and also a further gas  diffusion  layer.  The current collector may be situated  or embedded in the porous conductive substrate or the gas  diffusion layer.  If used as a fueld cell anode,  a further small amount of noble metal is included in the porous catalytically active layer. Porous  electrodes of this invention may also be used in alkaline primary or secondary cells.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatus are provided for welding a stud to a workpiece and maintaining the area around the weld sub-stantially free of smut.  The existence of the smut detracts from the appearance of the workpiece and, if the workpiece is to be painted or otherwise covered with a coating material, the smut must first be removed.  A spark shield assembly has an outer end which is placed in contact with the workpiece around the stud.  Anti-smut liquid is first deposited from the assembly on the weld area around the end of the stud where the weld occurs thereby to eliminate the deposit of a coating of smut.  Air is then directed through the spark shield assembly toward the outer end thereof after the weld is com-pleted to aid in removing the anti-smut liquid from the spark shield assembly.

Abstract: THERMAL BLANKET            ABSTRACT     A thermal blanket includes an inflatable covering  with a head end, a foot end, two edges and an undersurface.   The covering  is inflated through an inlet at the foot end by  a thermally-controlled inflating medium.  An aperture array on the  undersurface  of the covering exhausts  the  thermally-controlled inflating medium from the covering.  Exhaust port openings  are provided at the edges of the covering to  vent the  inflating  medium, which enhances  circulation  of  the thermally-controlled   medium   through   the   cover.    An uninflatable  section is provided at the head end,  together with an absorbent bib attached to the covering, adjacent the uninflatable  section.  When inflated, the  thermal  blanket self-erects  and  provides a  bath  of  thermally-controlled inflating  medium to the interior of the erected  structure. The  enhanced circulation of the medium through  the  covers maintains  a relatively high average temperature  under  the blanket and a relatively uniform distribution of temperature in  the  inflating  medium which is  exhausted  through  the apertures into the structure's interior.  When the structure covers  a  patient,  the  uninflatable  section  provides  a relatively  unobstructed view of the patient's  face,  while the   absorbent   bib  maintains   a   relatively   sanitary environment in the area beneath the patient's head.
