  • Publication number: 20040024251
    Abstract: Methods of and systems for remediating hydrazine spills, solutions and hydrazine-contaminated objects including areas thereof. Initially, an aqueous solution comprising a dicarbonyl-compound can be prepared. The aqueous solution can then be provided for application to an object contaminated with a hydrazine group compound. The hydrazine group compounds are converted to a stable organic compound as a result of a reaction of the dicarbonyl-compound and hydrazine group compound. Conversion assists in the remediation of the hydrazine group compound from the object. The stable organic compound produced as a result of the reaction between the dicarbonyl-compound and hydrazine group compound can then be treated with a metal catalyst and hydrogen to produce glutamine or a derivative thereof. Both the stable organic compound and glutamine can undergo microbiological degradation without further remedial intervention.

  • Patent number: 5893806
    Abstract: A baseball instructional device and method for use teaches a hitter how to properly hit a ball depending on the location at which the ball is thrown by the pitcher. The device is capable of positioning a baseball, softball, or other ball, at proper hitting positions relative to the hitter, thus teaching the hitter when and where to swing to make proper contact with the ball. In addition to positioning the ball relative to the hitter, the device is provided with visual indicators to assist in teaching the hitter the proper location for striking the ball with the bat.
