Abstract: Sulfur dioxide in flue gas exhaust stream from fossil fueled boiler, is absorbed by a regenerative organic solvent in a centrifugal gas separator-absorber.

Abstract: A method for cleaning a flue gas stream continuously emitting from a thermal power plant fossil fueled boiler, and containing hazardous volatile organic vapors, heavy metal vapors, nitrogen oxides, sulfur dioxide, and carbon dioxide by cooling, condensing and gas liquefaction processes employing a heat recovery condensing heat exchanging, and a gas compressor-expander open heat cycle systems.

Abstract: Hermetically sealed electric driven gas compressor-expander for use in refrigeration system where low temperature waste energy rejected from the condenser is recovered and used to produce kinetic energy to assist driving the compressor, and thus reducing the electric power required for refrigeration.

Abstract: A pallet for use in drying ceramic cards that have product sites thereon, including a body having a plurality of openings therein defined by a series of highways, whereby the openings have the general shape of the product sites; at least one skirt extending perpendicularly from the body contains an open slot or recess located adjacent the front of the body; at least one skirt extending perpendicularly from the body contains an open, rearward facing, elongated slot adjacent the rear end of the body; a series of clusters of holes are provided along the perimeter of the body.

Abstract: Centrifugal gas compressor - expander for use in refrigeration system where low temperature level energy rejected from the condenser is recovered and used to produce kinetic energy to assist driving the compressor, and thus reducing the electric power required for refrigeration.

Abstract: Sulfur dioxide and carbon dioxide, emitted in flue gases are separated by gas centrifuge separators, and liquefied by gas mechanical compression and cooling means.
