Abstract: A process for selectively separating plutonium from uranium and other metals is disclosed wherein, in order to precipitate and remove the pertaining complexes, use is made of a sufficient quantity of a cationic compound containing at least one group adapted to assert affinity to polar surfaces and containing a radical which has little affinity to water, e.g. surface active agents and the like, and use is made of the capability of Pu.sup.4+ and U.sup.4+ to form nitrato-complexes and of the capability of Pu.sup.4+ and UO.sub.2.sup.2+ to form sulfato-complexes.

Abstract: The disclosure relates to a rotating pyrolysis drum for the thermal treatment of waste materials, such as domestic or industrial garbage or the like, with respectively one heated gas collecting chamber for addition and one heated gas collecting chamber for withdrawal, being provided at pertaining end faces of the drum, which chambers are connected to one another via bores in the end faces and by tubes extending through the interior of the drum. At least one seal assembly is arranged between the stationary heated gas collecting chambers and the drum. A seal disc is provided on the circumferential wall of a hollow connection member at the end face of the drum at the inlet side and, respectively, at the outlet side for pyrolysis residues and/or another rotating part of the drum. At the two end faces of the seal disc are arranged contact rings which are slid with play over the connection member and/or the other rotating part and these sealingly contact such end faces.

Abstract: The disclosure relates to a conveyor chain with a plurality of chain rollers, for conveying individual items or similar material handling applications, in which respectively two chain rollers are arranged coaxially at a predetermined distance with respect to one another on a common chain pin in such a way so as to be able to rotate, whereby side bars laterally arranged on the chain pins are used to connect respective sequentially arranged chain rollers, and the individual chain components are adapted to form an endless chain. The chain also includes conveyor rollers on those chain pins which are respectively arranged between two adjacent chain rollers of the chain, and these conveyor rollers have a larger diameter than the chain rollers. Recess-like depressions which are formed between two adjacent conveyor rollers in the chain are filled by bridge-forming space members which are secured on the respective chain pins, or on sleeves.

Abstract: The apparatus described basically includes a vessel (10) which has a horizontal transparent window (11) and contains an index liquid (12). An optical fiber (13) is mounted in this vessel perpendicular to the window (11). Light (14) is launched and focused by a condenser (15) onto fiber (13). The light cone of aperture angle (2.beta.) due to the guided and leaky modes is eliminated using an annular mirror (16) that reflects the remaining portion of the aperture light cone (2.alpha.) escaping laterally from the fiber. This light reflected by the mirror (16) is focused by an annular condenser (18) and reflected onto a detector (20) by a flat mirror (19) with a hole in the center. Measuring the amount of light received by the detector (20) allows the refractive index of the fiber to be determined.

Abstract: Pyrimidine and s-triazine derivatives of formula (I) ##STR1## in which X=CH or N; Y=for example halogen, alkoxy; W=for example --S--CH.sub.2 --COOH, --O--CH.sub.2 --COO alkyl, --NH--CH.sub.2 --CONHCH.sub.2 CH.sub.2 OH; Z=for example 2,3-xylidino, and methods for the preparation thereof are described. The compounds show high antilipemic activity.

Abstract: An arrangement for conveying of materials on conveyer rollers is disclosed in which the rollers are arranged sequentially one behind the other and the ends are supported in bearings in carrying brackets. The roller shafts are driven, each roller shaft is furnished with a torque transmitter, and the roller shafts are prevented from axial shifting by way of the bearings. At least one carrying bracket is divided, into two parts, at the horizontal central plane of the roller shaft bearing, thereby providing an upper part and a lower part. Dish-like recesses are arranged in the upper part and the lower part, at a distance to one another and in sequence one behind the other, with each recess serving to receive a pertaining roller-shaft bearing.

Abstract: Comminuted waste material is introduced in the form of briquettes, pellets or granulates into a gastight rotating drum for the recovery of useful gas by pyrolysis. The size of the briquettes, pellets or granulates is from about 1 to 50 mm and they are brought to a dry substance content of more than 70%.

Abstract: 11-Acyl derivatives of 5,11-dihydro-6H-pyrido-[2,3-b][1,4]benzodiazepin-6-one, 6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepin-5-one and 5,11-dihydro-6H-benzo[2,3-b][1,4]benzodiazepin-6-one, their preparation and pharmaceutical compositions endowed with antisecretory, antiulcer, antimuscarinic, spasmolytic activities containing the same, are described.

Abstract: A traction drive fluid is described, containing as the base stock a compound represented by the general formula (I): ##STR1## wherein all the symbols are as defined in the appended claims. This traction drive fluid has a high traction coefficient, has a good thermal stability, is of low viscosity, is of low volatility and further is reduced in temperature dependency of viscosity. Thus it is suitable for use in continuously variable transmission of cars or industrial machines.
