    摘要： An apparatus is provided for cleaning poultry carcasses (20) having a cavity. A plurality of cleaning heads (80) are spaced about a sprayer carousel (50) that is rotatably mounted upon a vertical shaft (15). The cleaning heads are mounted upon a plurality of vertically oriented guide rails (54) which are spaced about the sprayer carousel. A circumferential cam (70) is fixedly connected to the vertical shaft inside the sprayer carousel. A cam follower (120) connected to each cleaning head follows the profile of the cam, displacing the cleaning head vertically along the guide rails. A conveyor transports the carcasses sequentially into and out of engagement with the sprayer carousel and an indexing member (58) maintains each of the carcasses in alignment with one of the cleaning heads. In response to relative movement between the fixed cam and the rotatable sprayer carousel the cam follower of each cleaning head follows the circumferential profile of the cam. In this way each cleaning head is inserted into the internal cavity of the carcass where the probe is maintained for a dwell period before being withdrawn from the internal cavity.

    摘要： The invention relates to the production of solid, powdery carboxylates of Rare Earth elements, particularly Nd, La, Pr, and Ce, where the ligands coordinated to the metal are preferably long chain, branched carboxylic acids, most preferably 2-ethylhexanoic, neodecanoic (versatic) and naphthenic acids. The process involves batch precipitation under controlled pH and temperature conditions of the product by utilizing Rare Earth water soluble salts, preferably Rare Earth nitrates, and salts of the carboxylic acid and washing the product with water, alcohol, water and alcohol mixtures or combinations thereof.

    摘要： Process for the preparation of an aqueous tar suspoemulsion by mixing a mixture comprising: (a) a viscous tar composition formed from a tar, from inorganic solids and, optionally, from water; (b) water (W); (c) a surface-active agent (SA) exhibiting an HLB of at least 10 and, optionally, (d) a thickening water-soluble polymer (TWP) with a molecular mass of greater than 10,000, the relative amounts of constituents (W), (SA) and, optionally, (TWP) being such that the viscosity of the (W) + (SA) + optional (TWP) mixture is preferably equal to or greater than the viscosity of the said tar, and then optional dilution of the mixture obtained with water or with an aqueous acidic solution. Application to the residues, containing sulphuric acid, resulting from the synthesis of white oils from petroleum fractions. The present invention further relates to a method for fluidizing acidic tars/sludges comprising contacting the tar/sludge with sulphuric acid and a surfactant. Optionally, a carrier for the surfactant's incorporation into the tar/sludge can be utilized. This provides an effective process for cleaning sulphuric acid tars/sludges from containers/vessels such as transportation containers, pipes and storage tanks. Preferably, the process comprises the additional step of regeneration of sulphuric acid from the fluidized tar/sludge.
