Abstract: The invention relates to a drive device for a hinged side window (1) of a vehicle, said drive device having an actuating drive (8) acting on a operating lever (4) via a transmission element (9), the operating lever (4) being fastened at one end to the hinged side window (1) and at the other end so as to be fixed to the body, and a reduction gear being arranged in the region of the operating lever (4), there being provision, according to the invention, for the reduction gear to be a worm gear with an involute toothing.

Abstract: A lubrication system for supplying a portion of the engine lubricant to one or more gear devices driven thereby and return to the engine independent of whether the gear devices are being driven at the time. Thus even when the engine is idling engine lubricant is circulated through the gear devices to maintain the temperature of the lubricant circulating through the gear devices within a relatively narrow temperature range. Also, the lubricant level within the gear devices will be maintained without the need for inspection of the gear devices as long as the engine lubricant level is regularly checked and maintained either manually or automatically. Further, by changing the engine lubricant at regular service intervals or using an automated lubricant change system, the quality and level of the lubricant in the gear devices is also maintained.

Abstract: An aqueous acidic solution for forming a rare earth element containing conversion coating on the surface of a metal, said solution being chromate-free and including effective quantities of at least one rare earth element (as herein defined) containing species, an oxidant and at least one accelerator, comprising a metal selected from Groups VA and VIA of the Periodic Table.

Abstract: A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.

Abstract: The described current distributor has a bus bar, a plug socket connected to the bus bar, at least one contact element which comprises an access connection, a consumer tapping and an element connecting the access connection and the consumer tapping, at least one plug connection for the plug contacts of a protective switch, which has a plug socket of the bus bar and an access socket of a contact element, and two signaling lines. In order to produce such a current distributor inexpensively and to ensure reliability of operation, it is provided in accordance with the invention that the contact element comprises a one-piece member.

Abstract: A gas turbine and a method for operating a gas turbine includes a combustion chamber, a turbine having rows of blades, an air compressor, a combustion-air line for feeding compressed air into the combustion chamber, a fuel supply unit, at least one fuel line, at least one cooling-air line. Some of the blades have an interior defining cavities whereby first cavities direct at least a portion of fuel to the combustion chamber through the first cavities at least in a section of the blades, thereby preheating the fuel before being introduced into the combustion chamber. The system defined by the first cavities and the section of the blades is closed relative to an interior of the gas turbine. Second cavities fluidically connect to the air compressor and receive at least a portion of the cooling air for cooling the blades.

Abstract: Production-induced tolerances in the assembly of components involve very high outlay if, after the assembly, these components have to be located in a certain position in relation to one another. The novel tolerance-compensation device is intended to render the position of the components adjustable in relation to one another, assembly also being simplified.

Abstract: A block copolymer of a hydrophobic block of one or more hydrophobic monomers and a hydrophilic block of one or more hydrophilic monomers is prepared by polymerizing a hydrophobic monomer to prepare the hydrophobic block, using a free radical polymerization process using a stable free radical agent, preserving a stabilized active polymerization site on the hydrophobic block; adding a hydrophilic monomer to the stabilized active hydrophobic block; and further reacting the mixture to effect polymerization of the hydrophilic monomer. The polymerization of the hydrophilic monomer is conducted in an amidic solvent in which the hydrophobic block and the hydrophilic monomer are soluble.
