Patent number: 4652383Abstract: A gelled concentrate composition contains 70 to 30 weight percent gelled liquid and 30 to 70 weight percent solids component. The solids component comprises a fine powder of an ammonium compound and a vinyl polymer gelling agent. The gelling agent is present in the amount of 0.5 to 8.0 weight percent of the total composition. The resulting gelled concentrate, stable up to 18 months in storage, is useful in extinguishing fires.Type: GrantFiled: January 21, 1986Date of Patent: March 24, 1987Assignee: Energy & Minerals Research Co.Inventors: William B.

Patent number: 4156593Abstract: A slurry of coal and a liquid which includes a leaching agent is directed through a chamber. The coal particles are comminuted and cavitation is induced in said slurry while the slurry is in the chamber by contact in the slurry with a resonant vibration transmitting member. Thereafter, the liquid is separated from the comminuted particles.Type: GrantFiled: October 4, 1977Date of Patent: May 29, 1979Assignee: Energy and Minerals Research Co.Inventor: William B. Tarpley, Jr.
-
Patent number: 4156594Abstract: A thixotropic gel fuel composition capable of being used in standard type oil burners comprising about 5 to about 75 volume percent of a solid carboniferous combustible material suspended in a liquid fuel and about 1 to about 10 weight percent of a substantially completely combustible gelling agent, the composition having a yield stress of about 20 to about 300 dynes per square centimeter. The composition may also contain ash modifiers.Type: GrantFiled: December 5, 1977Date of Patent: May 29, 1979Assignee: Energy and Minerals Research Co.Inventor: William B. Tarpley, Jr.
