  • Patent number: 4326164
    Abstract: An electrical resistance corrosion monitoring probe having a single lateral face of each of two rectangular prismatic elements of similar temperature-resistance characteristics but different thicknesses exposed to the corroding environment. Both the faces are corroded away, but the resistance change is different due to the inverse relationship between resistance and cross-sectional area. A measurement bridge network is used to monitor the change in cross-sectional area of both elements. A preferred probe embodiment, employing resistance elements having equivalent thermal masses and electrical resistances, as by using elements of the same material and of substantially equal lengths and cross-sectional areas, allows the use of a complementary measurement bridge network in its most sensitive region.

  • Patent number: 4312969
    Abstract: This invention relates to an exothermic emulsion polymerization method characterized by the presence of a low boiling fluid as a component of one of the phases of the emulsion system, said low boiling fluid having the following characteristics:(1) It is sufficiently inert so that it does not interfere with the polymerization reaction(2) It is capable of maintaining by reflux the polymerization system at relatively even and homogeneous temperature.This is exemplified by the use of a halogenated hydrocarbon boiling below about 50.degree. C. as the low boiling fluid.
