Abstract: Therapy is provided to living tissue by contacting the living tissue with at least one reservoir loaded with cells or a therapeutic composition, wherein the reservoir is in fluid communication with at least one conduit that includes a refilling port. A constituent selected from (a) cells, (b) bioagents from the cells or (c) the therapeutic composition is released from the reservoir to the living tissue. The reservoir is then refilled with (i) cells, (ii) nutrients for cells, or (iii) additional therapeutic composition; and (a) cells, (b) bioagents from the cells or (c) the therapeutic composition continue to be released from the reservoir to the living tissue after the refilling.

Abstract: An artist palette kit consisting of a reusable storage container, a foldable support palette, and a plurality of disposable palette sheets. The backing support is preferably made of single piece of 16 inch by 12 inch paperboard having a centrally disposed living hinge that allows the backing support to fold onto itself forming a palette shaped support that can be held in one hand. The palette sheets are constructed of aluminum foil, or a paper material that is impregnated with foil, to allow a fixed configuration when folded. The foil has a matte finish and is used by the artist for placing of paints thereon while painting. The foil palette sheet allows for ease of disposal of paint by carefully folding the foil onto itself so that no leakage occurs before discarding. Alternatively the foil palette sheet further allows for ease of disposal of paint by carefully folding the foil onto itself and placing the paint into a chilled area for later reuse.

Abstract: An electrically conductive cellulose composite includes a cellulose matrix and an electrically conductive carbonaceous material incorporated into the cellulose matrix. The electrical conductivity of the cellulose composite is at least 10 ?S/cm at 25° C. The composite can be made by incorporating the electrically conductive carbonaceous material into a culture medium with a cellulose-producing organism, such as Gluconoacetobacter hansenii. The composites can be used to form electrodes, such as for use in membrane electrode assemblies for fuel cells.

Abstract: A method for the deposition of metals in bacterial cellulose and for the employment of the metallized bacterial cellulose in the construction of fuel cells and other electronic devices is disclosed. The method for impregnating bacterial cellulose with a metal comprises placing a bacterial cellulose matrix in a solution of a metal salt such that the metal salt is reduced to metallic form and the metal precipitates in or on the matrix. The method for the construction of a fuel cell comprises placing a hydrated bacterial cellulose support structure in a solution of a metal salt such that the metal precipitates in or on the support structure, inserting contact wires into two pieces of the metal impregnated support structure, placing the two pieces of metal impregnated support structure on opposite sides of a layer of hydrated bacterial cellulose, and dehydrating the three layer structure to create a fuel cell.

Abstract: A seating support cushion system has a seat cushion with an H-shaped inflatable cell, with the sides of the "H" extending parallel to a cushion axis that corresponds to the longitudinal axis of a person sitting on the cushion, and therefore parallel to the thighs. The crossbar cell is midway in the cushion, forward of the location of the position of the ischial tuberosities of a person supported on the cushion. A pair of inner cells fill in the voids of the "H" shape, with one cell in the rear of the cushion positioned for supporting the ischial tuberosities. This rear cell also preferably has a recess for receiving the coccyx without significant pressure, and a secondary crossbar portion adjacent to the crossbar cell. A back cushion has two sets of alternatingly inflated, laterally extending cells forming a spinal recess and contoured to conform to the shape of a person's back.

Abstract: A truck trailer adapted to carry fluid and dry freight includes two spaced fluid carrying tanks respectively positioned adjacent the front and rear ends of the trailer and a dry freight section between the two tanks. The rear fluid carrying tank is selectively removable from the trailer to allow dry freight to be loaded through the rear end of the trailer into the dry freight cargo section of the trailer.

Abstract: Shelves are disclosed having slots cut in their ends, into which are threaded straps comprising loops of webbing. Top-straps are for supporting the topmost shelf from a wall, and shelf-straps are for supporting a shelf from a shelf above. The modularity of the pre-formed loops permits a very versatile system. Long shelves are also shown with T-slots by which the shelf can be supported intermediately.

Abstract: A locking device for a looped cable includes a casing in which one end of the cable is anchored, there being a passageway through the casing through which the other end of the cable can be passed. Within the casing is a cable clamp for reducing the size of the passageway, the clamp being threaded on a screw and movable to change the size of the passageway by rotation of the screw. The screw is rotatable by rotation of a lock mounted in the casing, the lock being rotatable by a key. The clamp cooperates with a bed to define the passageway, the clamp and bed having intercalated pyramidal teeth which can exert a vise-like grip on a cable of normally cylindrical shape.
