International Classification:

H01M 6/04
H01M 6/12

US Classification:

429162, 429178, 429206, 429245

Abstract:

A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell. The opposing sides define a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises a single frame or two separate frames housing the anode and cathode material. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

Abstract:

A wafer alkaline cell of a laminar structure is disclosed. The cell has a pair of opposing sides comprising at least the majority of the boundary surface of said cell and defining a short cell dimension therebetween. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. The cell comprises a single plastic frame or two separate plastic frames housing the anode and cathode material. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The anode assembly has an anode material therein typically comprising zinc and the cathode assembly has a cathode material therein typically comprising manganese dioxide. The cell is durable and preferably rigid, has elongated leak block paths, and resists electrolyte leakage.

US Classification:

429162, 429209, 429241

Abstract:

A wafer alkaline cell of a laminar structure is disclosed. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. There may be one and desirably two anode frames securing an anode current collector sheet sandwiched therebetween. There may be a cathode frame bonded to the anode frames. There is an anode current collector sheet within the anode assembly. There is a cathode current collector sheet, optionally with an attached metal mesh embedded within the cathode assembly to assure good electrical contact with the cathode. Alternatively, a cathode endplate with spring action is employed which can move in response to changes of volume or pressure within the cathode, thereby maintaining good contact. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The cell is durable and preferably rigid and resists electrolyte leakage.

Filed:

Feb 6, 1989

Appl. No.:

7/306093

Inventors:

Charles E. O'Brien - Saugus MA

International Classification:

B27B 2100
B25H 106

US Classification:

182151

Abstract:

A knock-down support stand or trestle for use as a sawhorse on construction sites and for home use constructed of pre-cut or pre-formed components that are readily assembled together in interlocking engagement without need for use of fasteners of any kind. As the load on the support stand increases, the components of the support stand become more securely interlocked together.

International Classification:

A42B 320

US Classification:

2425

Abstract:

The protective headgear, such as a catcher's/umpire's headgear, is defined by a forward substantially concave rigid shell and a rear substantially concave rigid shell articulately interconnected together adjacent upper portions thereof. Resilient straps snap-secure opposite lower side portions of the forward shell to opposite lower edge portions of the rear shell. A rigid framework having a relatively large view opening is fastened to a view opening of the forward shell to afford maximum visibility to the user.
