  • Patent number: 5575063
    Abstract: A spin pack for spinning synthetic fibers from two or more liquid polymer streams includes a supply for at least two polymer streams to the spin pack; a spinneret having extrusion orifices; and flow distribution plate sets. The flow distribution plate sets include at least one patterned plate having edges which define a substantially regular two-dimensional geometric shape, a substantially planar upstream surface, a substantially planar downstream surface and at least one flow distribution pattern stenciled therein by cutting through. For each patterned plate, at least one boundary plate stacked sealingly adjacent thereto and having edges which define a substantially regular geometric shape, a substantially planar upstream surface and a substantially planar downstream surface. The boundary plate has cut-through holes connecting the upstream surface with the downstream surface to form at least one flow-through channel to allow fluid flow through the patterned plate but otherwise is substantially solid.

  • Patent number: 5569715
    Abstract: The present invention is directed to a process for forming a hydrophobically modified emulsion, and the modified emulsion polymer obtained thereby. The emulsion polymer is formed by first combining hydrophobic polymeric compound and .alpha.,.beta.-ethylenically unsaturated monomer, to form a mixture and subjecting the mixture to high stress techniques to form surfactant stabilized particles of the hydrophobic polymer and monomers, in the aqueous phase. The .alpha.,.beta.-ethylenically unsaturated groups within the particles are co-polymerized to form a hydrophobically modified core polymer. Additional monomers including at least one .alpha.,.beta.-ethylenically unsaturated hydrophilic monomer are then added to the core polymer and polymerized by emulsion polymerization, to form a hydrophobically modified emulsion polymer.

  • Patent number: 5569522
    Abstract: An anticopying film (2) for covering documents (1) appears opaque in vertical plan view (5) as a result of total reflection for protection against copying and appears transparent in the oblique viewing direction (6), the film having an irregular sawtooth structure (3). This makes it virtually impossible to produce an identical second film with the aid of which, by placing said second film on top, the effect of the anticopying film (2) might be eliminated.
