    摘要: A tensioning device for chain or belt drives comprising a damping piston guided in a cylindrical housing and loaded in the chain tensioning direction by a compression spring located in the housing, wherein a high pressure chamber for hydraulic fluid is situated between the housing bottom and the damping piston and is open via a leakage gap formed by the guide bore of the housing and the damping piston and closed with respect to an oil reservoir by a non-return valve, the hydraulic pressure in the high pressure chamber during the operation of the tensioning device being higher in the cold state than in the heated state due to differences in viscosity, characterized in that the high pressure chamber is delimited by an additional piston acting as an overpressure piston on which a second compression spring acts in the direction of the high pressure chamber, the overpressure piston being able to bear against a fixed stop and the spring force of the second compression spring and the effective surface of the overpressure piston are so dimensioned that in the cold state, the overpressure piston is displaceable by the force applied to it by the hydraulic pressure and in the heated state, it is retained at the fixed stop by the second compression spring.

Specific ligands L.sub.1, L.sub.2 and L.sub.3 which are useful in the ruthenium complexes of the invention are, e.g., 2,2'-bipyridine, 1,10-phenanthroline benzbathophenanthroline or bathophenanthroline groups. Groups which are useful for conferring water-solubility on said ligand are, e.g. sulfonic acid groups which are preferably present in the form of their salts. Useful spacer groups are e.g. an alkylene groupcontaining 1-8 carbon atoms and which is optionally substituted with --SO.sub.2 --NH--, --S--, --O--, --COO-- or --CO--NH-- groups. Useful reactive groups to which the immunologically active material is coupled, are e.g. --COOH, --I, --NH.sub.2, --NCS or --SO.sub.2 Hal groups. The ruthenium complexes according to the present invention can be detected with great sensitivity by fluorescence spectroscopy and are thus useful in fluorescense immunoassays.

    摘要: A control system for a hydrodynamic-mechanical transmission of the type having a by-pass clutch to by-pass the hydrodynamic torque converter includes a main control valve to disengage the forward gear clutch element and thereby the engine from the driving wheels when the accelerator pedal is released. At the same time, the main control valves causes the by-pass clutch, if engaged, to disengage. When the accelerator pedal is depressed, the forward gear clutch element re-engages as well as the by-pass clutch, but since the by-pass clutch is still disengaged at the time the forward gear clutch element re-engages, the jerking motion that may otherwise occur is absorbed in the hydrodynamic torque converter.

    摘要: Ultrasonic transducers, of an electrical capacitor formed of a counter-elrode and a synthetic material film lying thereon, held by a clamping ring and metallized on one side, are used amongst other things for running time measurements in flow field examinations in wind tunnels. It is in that case important to disturb the flow as little as possible by the spatial dimensions of the ultrasonic transducer and by the necessary mountings and current feeds. For the solution of the problem, it is proposed to fasten the counter-electrode (2) and the clamping ring (3) holding the synthetic material film (5) electrically insulated therefrom on a conductor plate (6) and electrically conductively to connect each with a respective conductor track portion (7, 8 or 7, 10, 8, 9).

    摘要: A pneumatic control system is disclosed for an automatic transmission for a vehicle of the type having a mechanical planetary gear train with hydraulically actuatable gear elements. A manual control valve dependent upon the position of the transmission gear select lever conveys a pressure medium, for actuating a gear shift element associated with the selected gear when said lever is moved to one of the forward gears of the transmission, through a pressure medium line connected between the manual control valve and the gear shift element. The control system comprises a main control valve dependent upon the position of the accelerator pedal for exhausting the fluid in the gear shift element for disengaging the gear shift element in operating states of the vehicle at least when the vehicle is stationary, the transmission gear select lever is moved to the drive position (D), and the accelerator pedal is released.
