  • Power supply for an ozone generator with a bridge inverter
    Patent number: 5285372
    Abstract: A full bridge switching power supply is coupled to an ozonator load via a series resonant circuit having a resonant frequency above the switching frequency. Power output is controlled by varying the duration of the times when diagonal switches are conducting, and the output voltage has a longer rise time than fall time due to there being intervals between the conduction periods of diagonal switches during which one of the switches is turned on to permit resonant current flow. The driving voltages for attaining this action are symmetrical rectangular waves of identical shape having different phases that are derived from out of phase pulses where width is varied by the timing of their trailing edges.

  • Composition and process for treating metal
    Patent number: 5281282
    Abstract: Heating an aqueous mixture of a fluoroacid such as H.sub.2 TiF.sub.6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed e with water soluble and/or water dispersible polymers that are polyhydroxyalkylamino- substituted polymers and/or copolymers of p-vinyl phenol, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting.
