The invention relates to a tensioning arrangement with a damping device for a belt drive. The tensioning arrangement includes a combination of a pivotal roller lever which supports a tensioning roller, a tension spring engagable with the roller lever and a damping device attached to the roller lever.In order to facilitate a rapid installation and tensioning of the belt on the belt drive, the end of the tension spring opposite the roller lever is connected with a pivotable spring tensioning lever, which spring tensioning lever is selectively movable from a position where the belt is provided with no pretensioning to a pretensioning position where the spring exhibits a predetermined pretensioning force at the belt tensioning roller.

An air guide casing includes an air filter, an air throttle valve, an exhaust gas recycling pipe, a mixing chamber in fluid communication with the recycling pipe, and a distributor chamber in fluid communication with the mixing chamber and at least one cylinder of an internal combustion engine. The air guide casing is provided with means for collecting a mixture of recycled exhaust gas and filtered intake air and means for distributing that mixture to the cylinders. Thus, the air guide casing provides a separate mixing section in the air guide casing to achieve good mixing of the air for combustion with the incoming exhaust gas prior to introduction of the exhaust gas and clean air into the distributor chamber.

A connecting line between a compressor of an exhaust gas turbocharger flangedly connected at the exhaust gas manifold of an internal combustion engine and a suction pipe which consists of a first line part secured at the suction pipe and of a second line part which is coupled with the exhaust gas turbocharger by way of plug-in coupling sections and with the first line part by way of a line bridge fixed at the engine and provided with plug-in coupling sections. The line bridge encloses a mixing space between its coupling sections, in which exhaust gases controlled by an exhaust gas valve are fed to the through-flowing charging air.

The invention relates to a method for operating a steam turbine power plant comprising at least one steam generator that is fueled by lignite, wherein the lignite is indirectly dried in a fluidized bed dryer that is heated at least partially with steam from the water-steam circuit of the steam generator. Said method is characterized in that the flue gas from the steam generator undergoes gas scrubbing to remove CO2 and that the energy required for the gas scrubbing is at least partially extracted from the drying process in the fluidized bed. The invention additionally relates to a device for creating steam from lignite comprising a drying system for the lignite and a device to scrub CO2 from the flue gas, wherein the drying process and the CO2 gas scrubbing are thermally coupled to each other.

There are described new blue cationic oxazine dyes of the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are each C.sub.1-4 -alkyl, with R.sub.1 and R.sub.2 together with the nitrogen atom also being able to form a heterocyclic ring, and X.sup..crclbar. is an anion; these dyes are distinguished in particular by an excellent migration capacity on polyacrylonitrile fibres.
摘要:
A filter housing for accommodating at least one filter insert to filter lubricating oil, which is provided in the installed position with a geodetically upper assembly opening for inserting and interchanging the filter insert and with a geodetically lower base; the housing interior space is connected by way of two separate housing channels extending in the base, with one housing connection each for the inlet of dirty oil and for the outlet of clean oil; the housing interior space can also be connected with a housing connection separate from the housing connection for the inlet of dirty oil by way of a drainage connection adapted to be closed off by means of a closure device which can be opened at will.
摘要:
A process for the preparation of basic oxazine dyes of the formula ##STR1## wherein R represents a low molecular alkoxy or alkyl group which is substituted or unsubstituted, R.sub.1 represents a low molecular alkyl group which is substituted or unsubstituted, R.sub.2 represents a low molecular alkyl group which is substituted or unsubstituted or an aryl radical, and each of R.sub.3 and R.sub.4 independently represents hydrogen or a low molecular alkyl radical which is substituted or unsubstituted, and R.sub.1 may be attached to R.sub.2 and R.sub.3 to R.sub.4 through a heteroatom, and wherein the ring a can carry further non-ionogenic substituents or a fused benzene ring, and X.sup.- represents an anion, which process comprises treating a compound of the formula ##STR2## wherein R.sub.1, R.sub.2 and a have the meanings previously assigned to them, with nitrous acid in a polar, water-miscible solvent and adding to the resultant nitrosation mixture, without isolating the nitroso compound, a diamine of the formula ##STR3## wherein R, R.sub.3 and R.sub.4 have the indicated meanings and each of R.sub.5 and R.sub.6 represents hydrogen or a low molecular alkyl group.
