Abstract: A device for mechanically generating inhalable active substance particles from a consolidated medication supply and for conveying the active substance particles into the respiratory tract, wherein, in order to generate the active substance particles, there is a drivable face mill against which the front of a medication supply in the form of a ring-shaped body can be pressed, whereby the ring-shaped body forms the beginning of an inhalation tube ending in a mouthpiece and in that the housing surrounding the ring-shaped body and the face mill is provided with air inlet openings in the blade area of the face mill and said air inlet openings, together with the depressions located between the blades and the inhalation tube, form an air channel leading to the mouthpiece.

Abstract: A manometer device for continuous monitoring of the air pressure in vehicle tires is described which consists of a manometric capsule and an electrical indicator device associated therewith. A flatly conical membrane with a cylindrical projection is arranged transversely through the interior space of the manometric capsule. A permanent magnet is inserted in this projection. The membrane divides the interior space of the manometric capsule into two chambers, of which one chamber is stressed with a nominal pressure and the other chamber is connected to the pressure space of a vehicle tire. A stationary sensor, which is associated with the manometric capsule to be mounted on a rim flange, responds to linear magnetic field variations and transmits the latter to a terminal.

Abstract: In an exemplary embodiment a head with an installed television camera is present which head is connected in a plug-in fashion to a mobile tube section. The control of the orientation of the head during video exploration is effected by a system of hydraulic fluid encased Bowden cables which can transmit not only mechanical forces but also electric energizing and signal currents and which permit a conducting away of dissipated heat. The transition from the tube section to the head is sealed off by means of drawover seal.

Abstract: Pipette system for the volumetric extraction and linear deposition of a suspended material, in particular cells or particles. The pipette system consists of a capillary containing a piston inserted in such a way as to prevent the passage of liquids. Part of the rim forming the orifice of the capillary has a projection. The width of the projection determines the width of the smear regardless of the diameter of the capillary, even when the deposition of the suspension onto the slide or the like is contactless.
