摘要:
A center bearing for a shaft, in particular a propeller shaft, has a rolling bearing arranged on the propeller shaft and a bearing housing surrounding the center bearing. A slide ring in which the rolling bearing is axially displaceable is arranged over the outer periphery of the rolling bearing. A decoupling element is arranged between the slide ring and the bearing housing.

The invention relates to a method for elastographically examining tissue. Said method comprises the following steps: at least one mechanical wave that oscillates primarily or exclusively perpendicular to the direction of propagation thereof is excited in the tissue (31) which has first elastic properties at least at one first point in time and second elastic properties differing from the first elastic properties at least at one second point in time; and a first deflection or deflection rate of an oscillation of the wave is determined at the first point in time as a measure of the first elastic properties, and a second deflection or deflection rate of an oscillation of the wave is determined at the second point in time as a measure of the second elastic properties. The invention further relates to an apparatus for elastographically examining tissue.

An automatic apparatus for obtaining and analyzing a blood sample contains a supply of lancets and test strips, which are located alternately on a carrier band. A lancet or alternatively a test strip may be clamped on a holder, which is mounted so it is movable. The movement controller of the holder comprises a three-dimensional control curve and a guide element, which engages at different depths in the control curve as a function of its relative position. The control curve comprises two guide paths, which run on different parallel planes. The contour of the first guide path determines the movement path of the lancet and the contour of the second guide path determines the movement path of the test strip. The test strip executes a transverse offset perpendicular to the puncture axis of the lancet.

The invention relates to resource operating medium compositions containing additivated lubricants based on polyalkylene glycols and/or neopentyl polyol esters, which are additivated with alkylated triaryl phosphate esters which are suitable for lubricating refrigerators, air-conditioning systems, heat pumps and similar systems which are operated using carbon dioxide as an operating medium.
摘要:
Constant velocity joints or homokinetic joints are used for the continuous transmission of rotational movements and torques. They transmit the rotational movement of a driving shaft to a shaft to be driven without changing the speed or torque. The transmission takes place independently of the speed, torque, or the value of a diffraction angle and independently of the speed at which this diffraction angle changes. Constant velocity joints with a diffraction angle of 90° are equipped with specially shaped gear pairs, which are held together by a spring-loaded inner joint. In this joint transmission, a diffraction angle of 90° is achieved while the shafts to be connected to fixedly mounted bevel- and spur gear pairs are connected to each other, so that no spring-loaded inner joint is needed. Therefore, high engine speeds and high torques can be transmitted.
