Abstract: In a camshaft adjusting device comprising an adjusting mechanism for adjusting the phase positions of first and second camshafts with respect to a crankshaft driving the camshaft adjusting device, the adjusting mechanism includes an adjustment input and first and second outputs connected to the first and second camshafts respectively, with first and second transmission ratios, respectively, for changing the phase angles between the drive input and the first and second outputs respectively, at different rates when the adjustment input is actuated.

Abstract: In a method of controlling an internal combustion engine with a common rail fuel injection system including individual fuel storage chambers for the supply of fuel to the various cylinders of the internal combustion engine, a fuel pressure (pE(i)) is determined during a measuring interval (MESS) and is stored, the existence of a significant change in the fuel pressure is determined as an injection begin (SB=f(pE(i), Phi)) or an injection end (SE=f(pE(i)), Phi), a virtual injection begin is calculated by way of a mathematical function (FKT) depending on the injection end (SE), and the virtual injection begin (SBv) is used as the actual injection begin (SB) for the subsequent control of the internal combustion engine.

Abstract: In a bottom plate for closing the crankcase of an internal combustion engine including coolant and lubricant flow channels integrated into the bottom plate which consists of individual plates stacked on top of one another, a heat exchanger, which consists of heat exchanger plates stacked on top of one another as disposed on the bottom plate so as to form at least one common chamber therewith for transferring at least one of coolant and lubricant between the bottom plate and the heat exchanger.

Abstract: In a mass-sensitive sensor consisting of an acoustic surface wave component on the basis of shear waves, the sensor includes a substrate with an active surface carrying two different layers, one which is a parylene layer of a thickness of between 0.2 and <1.6 ?m, which has been produced on the substrate by a vacuum-based deposition method and is capable of generating Love waves and the second layer forms a utilization layer, which interacts with an analyte disposed in a medium contacting the utilization layer.

Abstract: In an intake system for an internal combustion engine having a cylinder head with at least one inlet duct per cylinder, an essentially flat control flap is supported in the inlet duct on a pivot shaft pivotally about an axis which is disposed in spaced relationship upstream from the control flap by way of side support arms such that, in an open position, the control flap rests against a wall portion of the inlet duct from where it can be swiveled into the intake duct into a flow directing turbulence generating position.

Abstract: In an insulating glass window comprising two spaced glass panels which are sealingly joined at their circumference to form a sealed space in which a roller blind device is enclosed, the roller blind device includes a windup drum with a blind wound thereon and having a free end connected to a pull rod, and pull members are arranged at opposite ends of the drum and the pull rod is connected to the pull members. The pull members are operatively connected to a shaft on which the windup drum is rotatably supported for synchronous movement of the pull members and an electric motor is provided for rotating the shaft and the pull members, the windup drum being rotationally connected to the shaft by way of a rotational torsion spring structure.
