Appl. No.:

7/805260

Inventors:

Edward A. Vitunac - Pittsburgh PA
Edward A. Zawadzki - Wexford PA

Assignee:

Falcon United Ltd. - Wexford PA

International Classification:

B09B 300

US Classification:

241 14

Abstract:

A process and apparatus are provided for breaking the glass components of articles comprised of glass and nonglass components and liberating the glass components from the nonglass components by subjecting the articles to controlled vibrations sufficient to break the glass without breaking the nonglass components. The apparatus is a vibratory device having a screen deck and a plate deck. The screen deck has holes through which the broken glass falls to the plate deck. The nonglass components remain on the screen deck. Thereafter, the nonglass components are removed by one or more of a variety of means. The glass may be further processed by cleaning, rinsing and further crushing to size the glass pieces. Glass of different types may optionally be separated by taking advantage of the differences in specific gravities between glass types.

International Classification:

C02B 120

US Classification:

210 45

Abstract:

An aqueous solution of an alkali metal silicate and a silicate setting agent containing polyvalent metal ions is mixed with waste material to convert the mixture into a consolidated stable earth-like material substantially insoluble in water. The material is pulverized and mixed with polluted waste water, with the mixture being maintained long enough for the pulverized material to react with pollutants in the waste water to reduce or remove them, following which the suspended solids in the water are separated from it, leaving the water improved in quality; that is, water that is materially less contaminated than before treatment.
