  • Patent number: 6680097
    Abstract: A self-adhesive film label, in particular for reusable bottles, is proposed which can be readily detached in conventional washing equipment. This is achieved by means of a self-adhesive label with a stretched film layer, which shrinks back at elevated temperature in the washing device. Since the adhesive of the label loses its adhesive force at this temperature, the label is rapidly and readily detached, supported by the surrounding washing liquid of the washing device.

  • Patent number: 6680098
    Abstract: The present invention relates to a self-adhesive label (1), designed to be adhered to and around a container by means of a self-adhesive layer (9′) on the back (9) of the label. This layer is protected up to the time of its use by the use of a release film having a smooth contact layer. The label is fastened to the substrate starting with one of its ends (2), which on its outer side (10) is provided with a release area (11), obtained by printing a layer thereon. The central portion (3) of the label is provided with a text or the like printed thereon. The layer has a larger length than the circumferential dimension of the container and will consequently with its other end (4) overlap said one end and be fastened to it by said self-adhesive layer. Said other end has sections (5, 6), which can be torn off and are separated from each other by perforations (7, 8), to be attached to an injection device or the like.

  • Patent number: 6680099
    Abstract: A means and method of enhancing the damage tolerance of adhesive bonds by introducing gaps in the adhesive to divide the adhesive layer into discrete regions. The gaps are created by placing strips of barrier material between the two adherends before the adhesive is put in place and cured. If the two adherends begin to debond along the interface between one of the adherends and the adhesive, the gap arrests the debonding process.

  • Patent number: 6680103
    Abstract: An improved packaging material may include a substrate which is normally susceptible to permeation by substances such as oil or grease. A colorant layer may be applied to the outer surface of the substrate. The colorant layer may be of a color chosen to closely resemble or to overpower the appearance of a stain on the substrate which would otherwise be caused by the substances. In this manner, the colorant layer serves to mask the stain which would otherwise be caused by substances permeating through the substrate. A second colorant layer may optionally be provided over the first colorant layer to provide a uniform background of a desired color. Graphics, e.g, text and/or images, may then be applied to the first or second colorant layer in a conventional manner.

  • Patent number: 6680137
    Abstract: An integrated biomass gasification and fuel cell system wherein the electrochemical reaction in the fuel cell is effected by providing the reactant gases from a gasifier. Fuel gas from the gasifier is directed to the anode of the fuel cell and at least a portion of the exhaust gas from the anode is directed to the combustor. The portion of the exhaust gas from the anode is then combusted to recover residual energy to increase the overall efficiency of integrated biomass gasification and fuel cell system. Also, the oxidant gas from the combustor may be directed to the cathode of the fuel cell.

  • Patent number: 6680139
    Abstract: A flat pack type fuel cell includes a plurality of membrane electrode assemblies. Each membrane electrode assembly is formed of an anode, an electrolyte, and an cathode with appropriate catalysts thereon. The anode is directly into contact with fuel via a wicking element. The fuel reservoir may extend along the same axis as the membrane electrode assemblies, so that fuel can be applied to each of the anodes. Each of the fuel cell elements is interconnected together to provide the voltage outputs in series.

  • Patent number: 6680141
    Abstract: Disclosed are a lithium battery and methods for the manufacture thereof. Such a lithium battery includes a stack of a negative electrode, a separator, and a positive electrode. In the manufacturing methods, a pattern of holes is produced in the negative electrode as well as in the positive electrode, and a polymeric material is caused to penetrate the holes, whereby the negative electrode, the positive electrode and the separator are stuck and pressed together. Moreover, the negative electrode and the positive electrode are provided with an alignment pattern which can be used for the purpose of aligning the electrodes. The presence of such an alignment pattern facilitates the alignment of the layers with respect to each other.

  • Patent number: 6680142
    Abstract: The invention relates to a microbattery made of bioelectroactive components based on biomimetic processes. Bio-derived electron donors and electron acceptors are separately encapsulated in at least one pair of polymerized phospholipid vesicles. Embedded within the vesicle walls are lipophilic electron mediators that facilitate the transfer of electrons across the vesicle walls. Each pair of vesicles is immobilized on a conducting surface. The pair of vesicles are isolated from each other to create a galvanic cell, in which electrons flow from high to low electrochemical potential. A high energy density battery can be achieved if the vesicles are immobilized on highly porous conducting substrates.
