Abstract: A method and corresponding device are provided for determining a flow speed in a fluid conduit. The fluid conduit is provided with first, second and third ultrasonic wet transducers, wherein respective connection lines between transducers extend outside of a direction of average flow of the fluid conduit. First and second measuring signals are applied to the first ultrasonic wet transducer and received at the second and the third ultrasonic wet transducer, respectively. The measuring signals comprise a respective reversed signal portion with respect to time of a response signal. Respective first and second response signals are measured and the flow speed is derived from at least one of the first and second response signals.

Abstract: A method for determining a flow speed of a liquid in a fluid conduit is provided. During a signal-generating phase, an impulse signal is applied to a first ultrasonic transducer. A response signal is then received at a second ultrasonic transducer. A measuring signal is later derived from the response signal, wherein the derivation comprises reversing a signal portion with respect to time. During a measurement phase, a liquid moves with respect to the fluid conduit. The measuring signal is then applied to one of the two transducers and a response signal of the measuring signal is measured at the other transducer. A flow speed is derived from the response signal of the measuring signal.

Abstract: A method and apparatus for the pelletization of plastics and/or polymers, in which a melt coming from a melt generator is supplied via a diverter valve having different operating positions to a plurality of pelletizing heads through which the melt is pelletized. The plurality of pelletizing heads have different throughput capacities and are used sequentially for the start-up of the pelletizing process, with the melt first being supplied to a first pelletizing head having a smaller throughput capacity and then the melt volume flow being increased and the diverter valve being switched over such that the melt is diverted by the diverter valve to a second pelletizing head having a larger throughput capacity.

Abstract: A compact battery-free event detector having a switching element, which can be remagnetized in a bistable manner by a magnet in a sensor coil which then provides an event pulse and supplies a non-volatile memory circuit with a downstream non-volatile display, is designed to detect recurring movements by virtue of the switching element being able to be moved back and forth relative to the magnet between the activation and regeneration fields of its two poles. The manual operation of an inhalation or injection piston in a medicament dispenser can therefore be detected, in particular, and a dose of medicament, for instance, can be monitored thereby. The display is preferably created using e-paper or e-ink technology which, like the memory circuit which is operated only sporadically, obtains its energy needed to change the indication from the event pulse from the sensor coil.

Abstract: An adjustment device for a carrier plate which can be pivoted about two mutually orthogonal axes and is configured to receive a motor vehicle mirror, includes one motor per axis for moving a non-rotatably and non-tiltably guided linear drive, which is in engagement via a socket with a joint ball on the carrier plate, and a funnel-shaped hub provided with a hollow shaft. A hollow spherical segment of the funnel-shaped hub engages, by spring tabs, in a depression in the form of a hollow spherical segment in the carrier plate, and a spherical segment of the carrier plate is axially elastically clamped in a hollow spherical segment of a housing for drive trains of the two linear drives, thereby locking the hollow shaft on the housing.
