  • Patent number: 4683082
    Abstract: Unfavorable interaction is prevented between (a) electroconductive particle fillers and (b) organic resin binders of the type which are normally instable with respect to viscosity when aged in contact with said fillers. Moreover, electroconductivity degradation is also avoided. In a preferred mode of the invention, the particle surface is treated with a coating of an interfacial pacifying agent such as a tetravalent tin compound which both enhances the electroconductive performance of the particles and also is sufficiently compatible with the resin binder to migrate into the binder sufficiently to avoid undue gelling of the binder by particle-borne contamination or residues of such contamination.

  • Patent number: 4648715
    Abstract: Multichannel electrophoresis apparatus employing electrophoretic light scattering as a means for characterizing the particles under study. The apparatus is characterized by the ability to measure light scattered simultaneously using a plurality of local oscillators incident at different angles from the same population of particles being subjected to electrophoresis. The apparatus is used with data processing means to analyze the large amount of scattering data which provide information on electrophoretic mobility, particle size, particle charge, electrophoretic mobility, zeta potential. An important aspect of the new apparatus is a markedly improved capability to segregate data related to diffusion effects from data relating to heterogeneous effects.

  • Patent number: 4592961
    Abstract: A coating composition having surprisingly superior physical properties, particularly when highly-filled with small particles and bonded to a flexible film of a polymeric substrate. The composition consists essentially of (1) a homogeneous binder formed of relatively hard, high-tensile, aromatic polyester compounded with a vinylidene chloride copolymer such that the copolymer serves as means to increase the elongation, toughness and heat resistance of the binder and (2) the filler. The process of forming such a binder comprises formation of a homogeneous polymeric solution wherein each of the polymers is intimately distributed within the same solvent phase.

  • Patent number: 4585674
    Abstract: A process for coating a wide moving web with the product of chemical reactants first brought into contact at a point proximate the glass surface. The process comprises a primary distribution of reactants (across the width of the substrate) through a row of small apertures, then a segregation through a secondary passage to a reaction zone at the surface of the substrate. Reactant distribution pipes are advantageously positioned and shaped to form only a gradual increase in width of the reactant flow path as they enter the reaction zone.

  • Patent number: 4571081
    Abstract: A light scattering interfacial tension spectrometer has a laser source of light directed, as an incident beam I.sub.i, through a focusing lens and a diffraction grating. The grating divides the incident beam I.sub.i into a main beam I.sub.m, undiffracted light, and a higher order, diffracted light, reference beam I.sub.r. The beam I.sub.r is passed through an attenuator and a diffraction focusing lens to a region under test, such as a liquid surface. The main beam I.sub.m, from the grating is transmitted through the common diffraction focusing lens to the test region where it is reflected. The reference beam I.sub.r is reflected from the test surface together with scattered light I.sub.s, and directed through an aperture to a photomultipler tube. The output of the photomultiplier is coupled to a pulse amplifier-discriminator and a photon correlator. For a liquid surface under test the output of the spectrometer provides a measure of the surface tension and the viscosity of the liquid.
