Granted: 1993-05-04
Abstract: Method of Preparing a Mixture of Chlorine Containing Substances Abstract The present invention describes a novel method of producing an aqueous solution containing chlorine dioxide.  The mixture is produced by mixing an organic hydroxy acid or carboxylic acid, an alkali metal chlorite or alkaline earth metal chlorite and water in specified steps.  Very high concentrations of chlorine dioxide may be produced by the method.  For example, lactic acid is added to water to form a first solution and mixed.  Sodium chlorite is then added to the first solution to form a second solution and mixed resulting in an aqueous solution of chlorine containing substances including chlorine dioxide.

Abstract: CERAMIC ORTHODONTIC APPLIANCE     Abstract An orthodontic bracket or similar orthodontic appliance is made of a polycrystalline ceramic having a translucency which minimizes visibility of the appliance when mounted on a tooth.  The ceramic is formed by  pressing a powder material, such as high purity aluminum oxide, and sintering to yield a single phase appliance having substantially zero porosity and an average grain size preferably in the range of 10 to 30 microns.  The substantially color-free ceramic appliance has desirable strength and other mechanical properties combined with a translucency which permits the natural color of the tooth to diffusely show through in a fashion tending to make the appliance blend with and disappear against the tooth.
