  • Patent number: 7820088
    Abstract: A process for making functional or decorative flakes or platelets economically and at high production rates comprises applying a multi-layer sandwich of vapor deposited metal and release coats in alternating layers to a rotating chilled drum or suitable carrier medium contained in a vapor deposition chamber. The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent soluble thermoplastic polymeric materials applied by vapor deposition sources contained in the vapor deposition chamber. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable organic solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free.

    Abstract: A release agent is flash evaporated and deposited onto a support substrate under conventional vapor-deposition conditions and a conductive metal oxide, such as ITO, is subsequently sputtered or deposited by reactive electron beam onto the resulting release layer in the same process chamber to form a very thin film of conductive material. The resulting multilayer product is separated from the support substrate, crushed to brake up the metal-oxide film into flakes, and heated or mixed in a solvent to separate the soluble release layer from the metallic flakes. Thus, by judiciously controlling the deposition of the ITO on the release layer, transparent flakes may be obtained with the desired optical and physical characteristics.

    Abstract: The present invention is directed to calendaring an electrode active admixture, such as of a transition metal oxide, and particularly silver vanadium oxide, into an electrode structure. To obtain electrode structures of a desired low basis weight requires calendaring a paste of the active material into a first sheet tape, which is subsequently subjected to secondary and ternary calendering steps. Secondary calendaring is performed in a direction reverse or orthogonal to that used to form the initial sheet tape. The final calendaring step is performed in a third direction aligned 180° with respect to the first direction, but with the second structure rotated bottom over top with respect to the orientation that formed the first and second structures. The ternary calendaring step provides for fibrillation of the fluoro-polymeric binder in a direction reverse to the initial direction to form the product low basis weight electrode active structure.

    Abstract: This application relates to a method for pellerizing and taking intensive measurements of a raw sample. The method includes homogenizing and pelletizing the sample that is to be subjected to compositional or intensive analysis. The raw sample is mixed with several solutions containing epoxies and activators based in carrier solutions or solvents, and ground to a fine powder or gel. The gel is partially dried and conformed to a pellet shape. The pellet is then cured such that the epoxy and activator solutions react and form a binding agent capable of maintaining the structural integrity of the sample pellet during intensive analysis. An intensive analysis instrument, such as LIBS, may then be used to ablate the surface of the pellet. The pellet provides consistent ablation of the sample material for accurate intensive measurements.

  • Patent number: 7137802
    Abstract: An apparatus for processing thermoplastic synthetic plastic material to be recycled comprises a first receptacle (1) and a second receptacle (2) for the material to be processed. Within both receptacles (1, 2) tools (21) for mixing and heating the material circulate around a vertical axis each. The material reaches the second receptacle (2) which is connected to an evacuating means (9), from the first receptacle (1) through a connecting conduit (3). The first receptacle (1) has above it an intake opening (19) for the material to be processed, and the mouth of the connecting conduit (3) in the second receptacle (2) is disposed at a higher level than the tools (21) circulating in this receptacle (2). The material processed is carried off the second receptacle (2) through a discharge opening (49) by means of at least one screw (47), whereby this receptacle is vacuum-tightly closed. A sluice (6) is connected to the intake opening (19) of the first receptacle (1) that also is connected to an evacuating means (9).

  • Patent number: 6969478
    Abstract: A method for fabricating a protective helmet includes the steps of: (a) providing a fiber-based filler, such as a fiberglass sheeting; (b) mixing course ceramic particles into a thermoset resin; (c) impregnating the resin/ceramic particle mixture into the fiber-based filler; (d) forming or molding the impregnated fiber-based filler into a shape of a protective helmet; and (e) curing the resin mixture impregnated into the fiber-based filler. The course ceramic particles are preferably created by chopping a ceramic material. The presence of the ceramic particles in the composite helmet substantially reduces the heat reflectance of the helmet; while also reducing the overall weight of the helmet, since the ceramic material weighs less than the portion of resin material that the ceramic material is being used in place of. Finally, because the ceramic particles are course, they will not all flow to “low spots” in the helmet during the curing process.
