  • Method for making polyurethane foam floor covering products with postconsumer carpet fibers
    Patent number: 9689112
    Abstract: Polyurethane floor covering products are formed from a web layer containing at least 30% by weight fibers. A cooled polyurethane foam formulation which includes at least one polyisocyanate, water and at least one polyol having an equivalent weight of at least 500 is applied to the web layer. The wetted web layer is then compressed to mechanically wet out the fibers, gauged and heated to cure the foam formulation.
    Type: Grant
    Filed: November 18, 2015
    Date of Patent: June 27, 2017
    Assignee: Dow Global Technologies LLC
    Inventors: Randall C. Jenkines, Thomas H. Perry, Jr.

  • Electrical conditioning of a platinum electrode useful in measurement in hypochlorite
    Patent number: 4612094
    Abstract: The present disclosure sets forth improvements in a cleaning procedure to clean electrodes exposed to hypochlorite in a measuring device. Typical measuring electrodes are made of platinum, gold, silver or other conductive metals. The electrode is dipped in a strong acid bath, a sacrificial oxide coated titanium electrode is placed in the bath and a DC power source is connected between the metal electrode requiring protection and the sacrificial electrode to create current flow until the surface has been treated. Current flow accomplishes the treatment after which the electrode can be removed and used in measuring hypochlorite concentration.
