Abstract:
An air cathode having multiple layered structure formed by at least a layer of base material, two sintered diffusion layers and a sintered activation layer in laminating shape wherein the base material is as the electric current collector which is made of metal wire net or metal foam net carrying at least two sintered diffusion layers made of hydrophobic carbon material by sintering attached to upper and bottom side in laminating shape; additionally, one of the sintered diffusion layer on the base material carries at least one sintered activation layer which is made of hydrophilic carbon material carrying transition metal oxide catalyst; the air cathode shall be used as a cathode for Zn/Air cell, Fuel Cell or electric capacitor particularly to prevent electrolytic solution from being affected by the environment air outside the Zn/Air cell and to enable the Zn/Air cell under dry environment condition to maintain a stable electric property for a long period of time.
Abstract:
In a door constructed of spaced apart compression molded skins reinforced with fiber glass with the core between the skins filled with foam to construct the door, an improved skin for such doors is constructed by adding specific pigments to the raw materials for such skins before compression molding occurs to achieve a surface which is superior in appearance to the skins of such doors which are painted and/or stained after such skins are compression molded and converted into a door. The specific pigments employed are titanium oxide �TiO.sub.2 !, ferric oxide �Fe.sub.2 O.sub.3 !, chromium oxide �Cr.sub.2 O.sub.3 !, and carbon black and are blended in different percentages to achieve different colors without loss of the integrity of the skin.

Abstract:
A door according to this invention is formed from two rectangular compression molded skins with each skin having inside surface and an outside surface and on its inside surface a plurality of projecting, parallel ribs along at least two of its edges, a hinge support having a plurality of grooves on its opposite sides with the grooves operable to interlock with the ribs of the skins along one side of the door when the skins are assembled with this support and an accessory support having a plurality of grooves on its opposite sides operable to interlock the ribs of the skins along the other side of the door when the skins are assembled therewith whereby no frame is required for the door when a foamed in place polyurethane core is formed between the skins. The door used interlocking members at its side and top edges and a preformed bottom panel or insert.
Abstract:
A two part grille with interlocking connections molded from opaque plastic allows one or more screens or filters supported inside the grille and provides a configuration which allows its parts to be fitted on opposite sides of an opening in a wall or a door locked together by a mortise and tenon joint so that no screws are necessary, and the two part grille further has intermediate spacers used to accommodate differing thickness of a wall or the like.
Abstract:
Synthetic doors composed a rectangular frame with of skins of compression molded sheets secured to opposite sides of the frame and a core of foamed plastics with a window light therein are improved with a novel glazing cleat for securing a window light in an aperture in such a door that includes plate that rests against edges the skins about the aperture, the plate having an upright rim engaging a face of a window light and downwardly directed flanges which, with tangs on a retainer member having a upright tab engaging the opposite face the window light when nesting with the plate sandwiches the skins between the flanges and tangs to take advantage of the mechanical strength of the skins. Further if a fire resistant plate is married to internal face of each skin, the cleat will take advantage of the mechanical strength of such plates in supporting the window light in the case of fires, even if the outer or exterior skin or skins are turned to ash by a fire. For increased fire resistance the core is formed of a fire resistant foam, such a phenolic foam.

Abstract:
A packaging structure of a low-pressure molded fuel cell comprises a hot melt adhesive layer, which is formed through a low-pressure molding process using a hot melt adhesive that has specific material properties and will become molten when being heated. The molten hot melt adhesive is injected into the cell via injection holes formed on a housing or a mounting element to flow through a C-sectioned flow channel, so as to tightly enclose and bond to edges of the air cathode and separator for the cell. After the hot melt adhesive is solidified, a chemical-resistant hot melt adhesive layer with good sealing and enclosing ability as well as high adhesion strength and elasticity, being bubble removed at controlled pressure and the hot melt adhesive material is formed to firmly bond to the cell components and tightly seal the cell, so as to effectively prevent electrolyte in the cell from leaking.
