STEPPED HEARTH I N C I N E R A T O R WITH POSITIVE C L E A N - O U T OF AIR F E E D - T U B E S John S Somodi assigned to Enercon Systems Incorporated
An inclined hearth incinerator for the incineration of municipal, and industrial/commercial solid waste optionally in conjunction with sludge, with a controlled amount of combustion air allows the even distribution of underfire air to an upper hearth of plural stepped hearths in the floor of the incinerator. A clean-out assembly includes a piston which automatically cleans out feed-tubes for combustion air. The feed-tubes are protected by being embedded in the hearth, or being disposed beneath the hearth. The piston and a ram on the hearth may be interconnected for reciprocation by an actuating means so as to provide synchronous to-and-fro movement of the piston and ram.
4479857 M E T H O D AND APPARATUS FOR RADON CONTROL Hugh M Barton assigned to Phillips Petroleum Company
A method of reducing the emanation of radon gas from radium in mine rock faces. Also disclosed is apparatus employing an anode in electrical contact with the mine rock face in a waterbearing formation and a cathode remote therefrom in the water-bearing formation, as well as a source of D-C voltage for applying a potential between the cathode and the anode for moving radium ions toward the cathode through the water-bearing formation from the mine rock face by electrolysis.
~7~79 PROCESS FOR DEWATERING SLUDGES Masanori Hashimoto, Masaaki Wakita, Yamato, Japan assigned to Kurita Water Industries Ltd A process for dewatering aqueous sludges of organic nature by adding to the sludge a cationic organic flocculant to effect a first stage agitation of vigorous intensity, and then adding thereto an anionic organic flocculant to perform a second stage agitation of mild intensity and subjecting the thus formed flocs to a dewatering operation, which process comprises the use of a cationic organic flocculant composed of any combination
