Hermann A Zinnen, Anil R Oroskar, Chin Hsiung Chang: Carbon dioxide removal using aminated carbon molecular sieves. Allied Signal, Harold N Wells, Thomas K McBride, John F Spears Jr, March 7, 1989: US04810266 (93 worldwide citation)

Acid gases such as carbon dioxide are removed from air or other gases using a unique carbon-based material. The material is a carbon molecular sieve prepared from oxygen-free precursors carbonized in the absence of oxygen. The pores of the material are then enlarged as by high temperature steaming. ...

Mark J O Hara, Marion R Surgi: Immobilization of lead and cadmium in solid residues from the combustion of refuse using lime and phosphate. Wheelabrator Environmental Systems, Thomas K McBride, John F Spears Jr, Eugene I Snyder, April 12, 1988: US04737356 (69 worldwide citation)

Solid residues arising from the burning of solid wastes have lead and cadmium sufficiently insolubilized to pass the EPA toxicity test only where the pH in the EPA test is between 7.5 and 12.0. Addition of water soluble phosphate, especially phosphoric acid, increases the immobilization of lead and ...
