Abstract: A method of recovering and converting organic waste material into more useful products. More specifically the organic waste is slurried with water, passed through hydrocyclones for desanding and desalting, then dewatered through a mechanical press. The dewatered, desalted solids can be used as soil ammnedment, peat substitute, growing media, fertilizer carrier, fuel for co-gen plants, or composted. The water may be reused for slurry, irrigation, or discarded.

Abstract: An improved method for processing of xanthophyll-containing vegetative crops to yield a relatively xanthophyll rich high protein, essentially non-fibrous friable when dry particulate fraction primarily derived from non-vascular plant leaf or petal tissue, and a separate tougher, particulate fibrous fraction derived principally from plant stem and the leaf vascular xylem and phloem network. A system (20) which is useful for carrying out a preferred method includes a drying assembly (22) for drying crop to a moisture content of 15-30% by weight, a fractionating hammermill (24) to separate crop into a high protein xanthophyll-containing fraction and a high fiber fraction, and individual, downstream high protein and high fiber fraction processing assemblies (26, 28). The hammermill (24) includes an elongated housing (48); a rotor assembly (56) is situated within the housing (48) and includes a plurality of spaced outwardly extending hammers (86) each presenting a rounded leading impact surface (88).

Abstract: Aminoalkylindans of the formula ##STR1## wherein A represents an alkylene group having 2 to 5 carbons in a straight chain, R.sub.1 represents a lower alkyl having 1 to 3 carbons or is a lower alkoxy having 1 to 3 carbons, B represents --CH.sub.2 -- or ##STR2## and R.sub.2 represents phenyl or phenyl-lower alkyl and the phenyl group in such substituents is unsubstituted or is substituted with 1 to 3 lower alkoxy groups, and acid addition salts of the amines.The compounds have hypotensive activity.
