The method involves producing ozone gas, introducing the ozone-containing gas into a mixing vessel that contains the aforementioned organic compound, agitating the organic compound in the presence of the ozone-containing gas, wherein the ozone-containing gas is at atmospheric pressure or at a pressure of up to about 150 psig., and releasing the pressure if pressures in excess of atmospheric are used.Type: GrantFiled: October 20, 1997Date of Patent: August 31, 1999Assignee: Quantum Technologies, Inc.Inventors: Robert E. Yant, Marilyn M. Hurst, David B. Galluch

Patent number: 5944912Abstract: An oxidizer, preferably hydrogen peroxide, is used for cleaning the finger holes in a bowling ball and for cleaning the inserts which are placed in those holes. The hydrogen peroxide is preferably provided as part of a solution which is substantially similar to a "hair neutralizer". However a simple hydrogen peroxide 3% solution can be used, where about 3% of the solution is hydrogen peroxide and about 97% of the solution is water, by weight. In this simple 3% solution, the only other chemical, other than water and hydrogen peroxide, which may in one embodiment be provided, is a stabilizer, in typically a small percentage. The hydrogen peroxide solution can be placed or soaked onto a towlette. The towlette should be placed in a sealed plastic packet to prevent it from drying out. The hydrogen peroxide solution can then be applied to cleaning the holes in bowling balls and the inserts in bowling balls, and can also be applied to known uses such as an antiseptic to be applied to skin.Type: GrantFiled: January 27, 1997Date of Patent: August 31, 1999Inventors: Michael Jenkins, Janice Jenkins
