  • Organosilicate resin formulation for use in microelectronic devices
    Patent number: 8178159
    Abstract: Silane compositions having an aromatic functionality and a ethylenically functionality and comprising a latent acid catalyst are deposited in two or more layers on a substrate. Each layer differs in light absorption properties from an adjacent layer. Some layers may have different curing mechanisms. Such a method is useful in forming antireflective coatings.

  • Method of achieving microbiological control in open recirculating cooling water
    Patent number: 5603840
    Abstract: The invention comprises adding bromide to a cooling water system containing corrosion and scale control treatment chemicals at elevated concentrations (40 ppm or greater). A fraction of the recirculating water is drawn off in a side stream and ozonated. Ozone oxidizes bromide to bromine which then serves as a biocide. The bromide levels are chosen such that the ozone/bromide reaction is preferred over the ozone/treatment chemicals reaction. Thus, the addition of bromide at elevated concentrations, while acting as a biocide precursor, serves to protect treatment chemicals necessary for corrosion and scale control.

  • Method for using ozone in cooling towers
    Patent number: 5415783
    Abstract: A method for increasing the effectiveness of ozone as a treating agent for alkaline cooling tower waters. This is accomplished by reducing pH of the solutions in contactor loops which supply ozone to cooling tower waters with an acidic substance.
