A material is provided that uses controlled electrical current derived from dissimilar galvanic materials to drive oligodynamic metal ions into solution.

Iontophoretic material

An improved battery having an anode, a cathode that includes a chemically reducible material into which is incorporated an amount of electrically conductive carbon microfibers sufficient to enhance the electrical conductivity of said chemically reducible material, and an electrolyte.

Battery

A closure system for use in repetitively opening and sealing closing an openable end of a pliable container includes at least one bowed band which is connected to the container, as well as at least one closure member. In certain preferred embodiments, bands are connected to opposing side walls of the container, with the bands being interconnected by the closure member. When the container assumes an open condition, the bands are generally located in offset planes and, when the container is in a closed condition, the bands nest with at least one side wall portion of the container being located between the bands. The closure member has spring characteristics which tend to bias the bands together when the closed condition is selected, yet permits the container to be readily maintained in the open condition when desired. In other preferred embodiments, a closure member which tends to coil up is utilized to establish the closed condition.

Closure system for pliable container

A material is provided that uses controlled electrical current derived from two dissimilar galvanic materials to drive oligodynamic metal ions into solution. Exemplary materials include carbon and silver.

Iontophoretic material containing carbon and metal granules

A closure system for use in repetitively opening and closing an openable end of a pliable container includes first and second shape memory elements that are adapted to be attached to side walls of the pliable container adjacent the openable end thereof. Each of the first and second shape memory elements includes an elongated, generally concave surface portion and an opposing, generally convex surface portion. In accordance with various embodiments of the invention, the shape memory elements are provided on the container with the concave surface portions facing each other when the pliable container is in an open condition to maintain the opposing side walls in a spaced relationship in order to permit enhanced access to an interior of the container. In each embodiment, when the openable end is closed, the generally concave surface portion of one of the shape memory elements assumes a nested position with the generally convex surface portion of the other shape memory element in order to maintain the side walls in a close bearing relationship at the openable end. The shape memory elements can be constituted by various bowed members, including plastic bands, metal strips and wires which can either be fixedly or rotatably mounted to the bag. The closure system has application to various types of pliable containers, including two-sided, multi-ply and gusseted bags. A method and apparatus for producing pliable containers incorporating the closure system of the invention is also provided.

Lithium battery with electrodes containing carbon fibrils

Rubber composition containing carbon fibrils and a pneumatic tire

A method of making randomly oriented carbons fibrils having a cylindrical constant diameter with c-axes perpendicular to their cylindrical axis, which are free of pyrolytically deposited carbon, with a diameter of between 3.5 and 70 nanometers, by dispersing carbon fibrils in a medium and separating them from the medium, by filtration or evaporation to form a porous mat or sheet.

Methods of preparing three-dimensional, macroscopic assemblages of

It has now been found that highly advantageous three-dimensional, macroscopic assemblages of randomly oriented carbon fibrils can be prepared which have relatively uniform physical properties along one, preferably two and most desirably three-dimensional axis of the three-dimensional assemblage. Preferred compositions prepared according to the methods of the invention have uniform physical properties along at least one dimensional axis and have relatively isotropic physical properties in at least one plane of the assemblage and most desirably are isotropic throughout the entire three-dimensional structure.

Three dimensional macroscopic assemblages of randomly oriented carbon

A polymeric composition having improved toughness and conductivity comprising carbon fibrils, at least a portion of which are in the form of aggregates, wherein, as measured on an area basis, substantially all of the aggregates are less than about 35 .mu.m in diameter. A polymeric composition having improved toughness and conductivity is prepared by combining carbon fibrils, at least a portion of which are in the form of aggregates, with a polymeric material, mixing the combination to distribute the fibrils in the polymeric material and applying shear to the combination to break down the aggregates until substantially all of the aggregates are less than about 35 .mu.m in diameter.

A novel charcoal briquet and ignition means is disclosed. The combustible briquet of the present invention comprises a central mass and at least one easily ignited, thin member extending outwardly from the mass such that upon igniting the thin member, propagation of an ignited region proceeds rapidly to the mass. Also disclosed is a holding member for a combustible briquet having at least one configuration incised in the surface to provide a holding force sufficient to retain the briquet.

Charcoal briquet and ignition means

A thermal imaging system is provided which includes a heat-sensitive element comprising at least one imaging layer having a selected depth dimension and having therein one or more spectrally absorbing organic materials responsive to the radiation employed for imagewise exposure. The percentage concentration of the organic material increases with depth in a predetermined manner so as to provide uniform heating depthwise within the imaging layer.
