Abstract: An endoscopic device for generating acoustic waves with a sheath defining a center axis contains a first transducer for generating a first beam of acoustic energy radiating outwards of the endoscope sheath and a second transducer for generating a second beam of acoustic energy radiating outwards of the endoscope sheath. Both beams have different directions and intersect outside of the endoscope forming a focus spot. The second transducer is linearly movable parallel to the center axis with respect to the first transducer to displace the second beam and therefore to displace the intersection of the beams and therefore of the focus spot.

Abstract: An apparatus for degassing fluids uses a pressure-resistant container, in which the fluid to be degassed is stored and in which low pressure for carrying out the degassing process is produced. The apparatus further includes a supply vessel, containing the fluid to be degassed, which surrounds the pressure-resistant container; and a valve connecting the container and the supply vessel. Connected to the pressure-resistant container in such a manner that fluid can flow is a piston/cylinder unit, the working piston of which opens or closes the valve due to the low pressure in the container in such a manner that the fluid flows in from a fluid supply surrounding the pressure-resistant container and the separated gas escapes through the container opening.

Abstract: A method and apparatus checks and adjusts the relative position of electrodes which form a so-called underwater spark gap device, particularly for medical purposes, and in which one electrode is fastened to the base part by means of at least one electrode holder. The method and apparatus employ an adjusting arrangement which positions the electrodes at a desired position with respect to axial displacement, angularity between the axes, and electrode spacing. By means of a relative movement of the adjustment arrangement, in a direction which is vertical with respect to an electrode axis, the electrode holder or holders are plastically deformed in such a manner that the electrodes, after the rebounding of the electrode holder or holders, are located at the desired position.
