    摘要: A method for manufacturing Pu.sub.2 -containing crystals by oxidizing plutonium in a heavily contaminated nitric acid starting solution to Pu.sup.6+, precipitating ammonium plutonyl carbonate containing crystals by reaction with ammonium- and carbonate ions and subsequent separating and calcining of these crystals. The nitric acid solution with the oxidized Pu.sup.6+ as well as carbonate and/or acetate ions and NH.sub.3 are dosed into an aqueous starting solution of ammonium carbonate or ammonium acetate in a concentration such that the mol ratio of carbonate and/or acetate ions to the Pu.sup.6+ -ions in the solution is at least 4:1 and plutonium containing carbonato- or acetato complex compounds which remain dissolved in the receiver solution, are formed, while difficult-to-dissolve metal hydroxide compounds are precipitated. Thereupon NH.sub.3 and carbonate ions are added to precipitate the ammonium plutonyl carbonate containing crystals.

    摘要: The present invention concerns a process for the production of cement clinker in rotary kilns with substitution of primary raw materials and fuels by use of residual materials containing minerals and combustible parts with moisture contents of up to about 65% without predrying. The process makes possible a material and/or thermal utilisation of residual materials in the case of saving of the clay and fuel sources and relief of dumping with simultaneous lowering of the emissions, above all NO.sub.x, in the cement rotary kiln.

    摘要: A method and apparatus for producing histological sections by means of a microtome are suggested. A histological section of predefined thickness is produced with a microtome from a block comprising a tissue sample. A carrier material is applied with an application apparatus onto the block prior to before production of the histological section. To ensure that the histological sections do not roll up, and to enable improved downline processing of the histological sections as compared with a carrier material embodied in the form of an endless strip and that the carrier material is cut out prior to application to a size and/or a shape that corresponds substantially to the cross-sectional area of the block; and that the cut-out carrier material is then applied onto the block. The suggested apparatus is designed to apply the carrier material onto a histological section to be prepared by a microtome.

    摘要: A crank drive system (10) of a shaft (11) of a microtome (1) encompasses a first and a second shaft (11, 12). The first shaft (11) is rotatable with a crank (13) and comprises a first transfer gear (14). The second shaft (12) comprises a second transfer gear (15). A rotation of the first shaft (11) is transferable from the first transfer gear (14) to the second transfer gear (15) to cause the second shaft (12) to rotate. To make possible, with a microtome (1), an advance or a lowering of the specimen (2) in two respective oppositely directed rotation directions with the same crank drive system (10), the crank drive system (10) is characterized in that a third transfer gear (16) is provided. The first transfer gear (14) is selectably engageable with the second transfer gear (15) or with the third transfer gear (16) so that as a result, while the rotation direction of the second shaft (12) is maintained, the rotation direction of the first shaft (11) is reversible.
