  • Patent number: 5698299
    Abstract: A multilayer laminated body has a determinate system of hollow passages and is formed by an assembly of flat layers of polymeric materials having major dimensions in orthogonal X and Y directions and a thickness dimension in a Z direction perpendicular to the X and Y directions. Selected ones of the layers have openings extending through in the Z direction, and other layers have canals formed in an X-Y plane. The openings and canals form parts of hollow passages so that assembly of multiple layers joins openings and canals forms complete and continuous passages through the assembled layers. Layers joined in pre-laminate assemblies are assembled together in precise relative positions for desired alignment of the canals and openings. The passages can be filled with optically conductive material or electrically conductive material and electrodes can be appropriately positioned for acting on fluids passing through the body.

  • Patent number: 5686178
    Abstract: An article comprising a non-conductive substrate, preferably of an environmentally degradeable character, having a thickness of an oxidizable metal coating thereon, and optionally an oxidation enhancingly effective amount of a salt, e.g., from about 0.005 to about 25% by weight of salt, based on the weight of oxidizable metal, present on the oxidizable metal coating. Also disclosed is a related method of forming such article, comprising chemical vapor depositing the oxidizable metal coating on the substrate. When utilized in a form comprising fine-diameter substrate elements such as filaments, the resulting product may be usefully employed as an "evanescent" chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidization of the oxidizable metal coating so that the conductivity and radar absorbance/reflectance characteristics of the chaff transiently decays.

  • Patent number: 5591508
    Abstract: The transfer of dichroic inks into stretched and oriented substrates to form stereoscopic polarizing images and the like can be improved by the use of coatings which enhance imbibition of the ink into the substrate. The coatings serve to hold the ink in situ for a sufficient period of time to permit absorption of the dye and transfer of rich colors while minimizing the problems of smearing and/or runoff of unabsorbed ink. The present invention is particularly use will in the adaptation of ink jet printing techniques to the formation of stereoscopic polarizing images.

  • Patent number: 5571601
    Abstract: A cleaning tape is edge-stabilized using an adhesive that is solvent resistant. The edge-stabilizing adhesive is a one-step cross-linkable formulation of polyvinyl alcohol, ammonium zirconium carbonate, an acetylinic surfactant and a non-silicone defoaming agent. The formulation is applied to the sides of a woven cotton cleaning tape roll and then is allowed to dry and cure. The resulting cleaning tape can be used in a surface buffing operation in which a solvent is applied to the cleaning tape, without contamination of the surface to be buffed by fibers from the tape or by the edge-stabilizing adhesive.

  • Patent number: 5571608
    Abstract: An embedded core laminate including a conductive reference plane interposed between two insulation layers, and further interposed between two conductive layers. The assembly is laminated using standard temperature and pressure laminating procedures. Holes for interconnect vias are preferably drilled into the reference plane before laminating. The resulting embedded core laminate has three conductive layers with relatively uniform separation, insuring improved impedance control on each PCB (printed circuit board). Since uniform separation is maintained from one PCB to another, multiple PCBs connected together using embedded core laminates according to the present invention allows minimum cross-talk and characteristic impedance variations from one PCB to the next.
