  • Patent number: 4756929
    Abstract: Densely packed high resolution printed wiring boards may be achieved by providing channels below grade in a substrate planar surface, thereby providing greater conductor width for closely spaced conductors. By mechanically removing the substrate surface between the channels, high virtual resolution is obtained with high quality conductors and insulation spacings of the order of about 0.003 inch, and with actual conductor widths of greater than 0.012 inch. Thus the packing density of printed wiring patterns may be increased significantly. Also the quality of conductor adherence and conductivity is improved. Thus a non-critical and inexpensive process unexpectedly provides an improved quality, more precise printed wiring pattern.

  • Patent number: 4752509
    Abstract: A method for the impregnation of wood to prevent attack by harmful agents such as decay fungi or mould fungi and bacteria by the application of an aqueous solution of an alkali lignin modified into a water-soluble form. Impregnation takes place in two stages, these being an initial stage in which the aqueous solution containing the lignin still in its water-soluble form and with a pH not exceeding 10 is applied to the timber, and a second stage in which the lignin is fixed as a water-insoluble form by the application to the timber of a weakly acidic aqueous solution containing metal ions by the addition of metal salt.

  • Patent number: 4751133
    Abstract: A layer or member particularly useful as part of a medical patch such as an anisotropic wound dressing, a transdermal skin patch or an incise medical drape and the processes for forming such a member. The member is comprised of a crosslinked thermoset aliphatic polyurethane elastomer. The elastomer is the reaction product of (1) isophorone diisocyanate, (2) a macroglycol and (3) a chain terminator having both hydroxyl and vinyl functional groups. Polycarbonate glycols or polyetherglycols having a molecular weight of 500-2500 Daltons are preferred macroglycols and isophorone diamine is a preferred chain terminator. In one embodiment, a member or polyurethane layer for use as a wound dressing or an incise medical drape is produced by applying a film-forming solution or dispersion as a thin film to a supporting release paper and treating the film to drive off the liquids and to activate a crosslinker.
