Abstract: For disposing of liquid pig manure by composting same with solid carbonaceous matter. The composting material is contained in a trough, and is turned by means of an apron, which is supported in a carriage for a travelling along the trough. The apron carries moving rakes which lift and turn the material. The apron can be set to traverse both backwards and forwards. The apron is angled to a bottom-leading configuration during traversing, and the apron is capable of being lifted, to change the angle, when setting up for reversing the traverse.

Abstract: This invention relates to the application of immobilized metal affinity chromatography to the purification of complement receptor proteins.

Abstract: A dye solution comprising a laser recordable dye and a solvent for the dye that has (a) a solvent functional group selected from esters, ketones and ethers; and (b) the solvent functional group has as hindering groups (i) at least one t-butyl group on one side thereof or (ii) two groups on opposite sides thereof selected from the group consisting of isoamyl, t-butyl, isobutyl and isopropyl; provided that both groups cannot be isopropyl and (c) the hindering groups are adjacent to the solvent functional group.

Abstract: Photographic elements are formed by (a) coating a first layer on a transparent support from a coating composition comprising an organic solvent, an alkaline aqueous insoluble, organic solvent soluble film forming binder, and a solid particle non-aqueous dispersion of a filter dye which is substantially insoluble in the organic solvent and readily soluble or decolorizable in alkaline aqueous photographic processing solutions at pH of 8 or above, and (b) coating a second layer on the opposite side of the support relative to the filter dye containing layer from an aqueous coating composition comprising a silver halide emulsion.
