Abstract: A method and an apparatus for generating particles are provided. The method may be a method for generating particles from a flowable medium, the method involving forming drops from the flowable medium, arranging the drops on a particle forming surface and solidifying the drops, thereby forming the particles. The apparatus may be an apparatus for generating particles from a flowable medium with a drop generator and a particle forming surface, the drop generator being formed to arrange drops on the particle forming surface and the particle forming surface may be adapted to contact the drops when the particles are being formed.

Abstract: The invention relates to an ultrasonic generator (1) with a resonator (3) for transmitting ultrasonic sound to a medium (6) arranged in a receptacle (5). In order to efficiently transmit the ultrasonic sound from the resonator (3) to the medium (6) via the receptacle (5) the resonator (3) comprises a clamping opening (4) for clampingly receiving the receptacle (5).

Abstract: An ultrasound system for the generation of low-frequency high-power ultrasound includes a resonator for transmitting the ultrasound to a medium. To safely handle the ultrasound system, the ultrasound system has a light source illuminating a workspace of the ultrasound system.
