Abstract: A cyclic adsorption process is provided in which two zones are employed--an adsorption zone and a heat storage zone. A fluid stream containing a solute to be removed therefrom is passed through the adsorption zone and the effluent is then passed through heat storage zone. The conditions under which the stream is passed through the adsorption zone are selected so that the rate of progression of the heat transfer front and mass transfer front are substantially equal. This results in an optimum temperature of the effluent stream for efficient heat recovery in the heat storage zone. During regeneration of the adsorbent, a fluid regenerating stream is passed through the heat storage zone where it is partially heated. At a point between the adsorption zone and the heat storage zone the regenerating fluid stream is further heated, via an additional heat source, and passed through the adsorbent zone. The amount of additional heat is sufficient to effectively desorb the adsorbent.

Abstract: A thin sheet apparatus is described as having a front and a back and having a central area and a frame area disposed around the central area. The central area is made of a fluid impermeable material having substantially planar surfaces. The frame area contains two sets of supply orifices and drainage orifices which are opposite one another. The frame area also contains a plurality of channels for each orifice which connects the orifice with the central area. The pluralities of channels for the first set of supply orifices and drainage orifices are located on the front of the frame area while the pluralities of channels for the second set of supply orifices and drainage orifices are located on the back.

Abstract: A method of forming a conductive carbon-plastic material having increased surface area and enhanced surface conductivity characteristics is described. A conductive carbon-plastic material is molded from a mixture containing particulate conductive carbon and plastic material. The surface of the resulting conductive carbon-plastic material is simultaneously abraded and embedded with carbon particles by the projection of a dry mixture of compacted carbon and metal particles against the surface by means of propulsion. This dry mixture of compacted carbon and metal particles is obtained by ball milling a mixture of specified amounts and sizes of carbon and metal particles. Zinc metal particles are preferred.

Abstract: A metal halogen cell, especially a zinc-bromine cell, employs a circulating electrolyte system containing a complexing agent to effectively remove cathodic halogen from the electrolyte during charging of the cell. The complexing agent is one which in the presence of halogen forms a water insoluble halogen complex. This separated and stored source of cathodic halogen can be returned to the cell during cell discharge.
