Patent number: 5355089Abstract: The combination of a main electrochemical cell (or battery cell) and a battery tester connected to the cell is disclosed. The battery tester is moisture sensitive, typically of the electrochemical type having a film-like construction comprising an anode layer, a cathode layer and electrolyte layer therebetween. The tester may be applied against the cell's outer surface. A moisture vapor barrier film is applied over the tester and adhesively secured to the cell's surface. The moisture barrier film is flexible, optically clear or at least translucent, and has a very low moisture vapor transmission rate. The moisture vapor barrier is preferably composed of mica film, but may desirably also be a film of polyparaxylylene or glass coated polymer. A hydrophobic hot melt, solvent-based or reactive thermosetting adhesive may be employed to bond the moisture vapor barrier film to the cell's surface. The moisture barrier film prevents ambient moisture from passing to the tester and interfering with its operation.Type: GrantFiled: July 22, 1992Date of Patent: October 11, 1994Assignee: Duracell Inc.Inventor: Jack Treger

Patent number: 5348726Abstract: The invention relates to the manufacture of manganese dioxide by a chemical process. The resulting manganese dioxide product takes the form of particles characterized by filament-like protrusions jutting out from its surface. The manganese dioxide particles having such surface features can be manufactured by reacting manganese sulfate with sodium peroxodisulfate in an aqueous solution. The process can be controlled to yield high density manganese dioxide. The manganese dioxide formed in the process can be deposited directly onto the surface of electrolytic manganese dioxide (EMD). The manganese dioxide product the is particularly suitable for use as a cathode active material in electrochemical cells.Type: GrantFiled: September 20, 1993Date of Patent: September 20, 1994Assignee: Duracell Inc.Inventors: Enoch I.

Patent number: 5174814Abstract: Retractable marker pens and ink formulations for marker pens. The ink formulation has particular utility as a fluorescent ink for highlighting text or print. The formulation reduces the rate of ink evaporation from conventional felt, fiber or plastic marker tips. This property makes the ink especially suitable for use in retractable marker pens which do not normally employ a separate tight fitting cap or a lint guard to protect the marker tip from ink evaporation when the marker pen is in non-use. The ink formulation exhibits excellent flow characteristics to conventional felt, fiber or plastic marker tips over a wide range in tip widths. The ink does not leak from the tip and does not penetrate paper so as to obscure text or printed material on the opposite side of the paper. The ink is composed of a fluorescent dye, selected from methine, xanthene and anthraquinone dyes dissolved in a multicomponent solvent system.Type: GrantFiled: June 20, 1990Date of Patent: December 29, 1992Assignee: Dennison Manufacturing CompanyInventors: Ann P.

Patent number: 4931385Abstract: Detection of bindable substances such as antibodies and antigens using enzyme linked immunosorbent assays having particular utility in home diagnostic applications. The preferred implementation of the invention is characterized by the steps of admixing a sample suspected of containing the bindable substance to be detected with an antibody-enzyme conjugate, immersing an antibody coated solid support into the mixture and then exposing the coated support to an activated chromogenic solution. The conjugate for use in the home diagnostic assay is preferably contained within a lyophilized mixture. The lyophilized mixture contains components which preserve the antibody-conjugate's reactivity and immunologic binding specificity even if the lyophilized mixture had been subjected to hot, humid environmental conditions. Active components in the lyophilized mixture include polyethylene glycol, sugars, and surfactant.Type: GrantFiled: November 21, 1988Date of Patent: June 5, 1990Assignee: Hygeia Sciences, IncorporatedInventors: Elliott Block, Izak Bahar, Frank Cole, Cheryl A.

Patent number: 4928995Abstract: Cover folders for permanently binding a stack of paper sheets without the use of fasteners. The cover folder has a binder spline which contains a quick drying adhesive which is protected by a removable protective film. The film is removed just prior to use to expose the adhesive. The cover folder allows for quick permanent binding of the stack of paper sheets which are pressed into contact with the adhesive. In alternative embodiments the adhesive may be applied directly to the binder spline from a dispenser and the stack of sheets then inserted in the spline. The dispenser may be in the form of a squeezable tube or pouch positioned in the binder spline. As the tube or pouch is pulled it ruptures, releasing adhesive into the spline channel.Type: GrantFiled: March 28, 1989Date of Patent: May 29, 1990Assignee: Dennison Manufacturing CompanyInventors: John H.
