  • Collimator for limiting a bundle of high-energy rays
    Patent number: 6730924
    Abstract: The invention relates to a collimator (1) for limiting a bundle of high-energy rays (2), which is emitted by a substantially point-like radiation source (3) and directed towards a treatment object (20) and used in particular for the stereotactic conformation radiotherapy of tumors. According to the invention the collimator (1) comprises a plurality of diaphragm leaves (4, 4′) which are arranged opposite each other and which are made of a radiation-absorbing material and which, by means of drive mechanisms, can be moved into the optical path in such a way that the contours and/or exposure period of said optical path can be freely defined, the front edges (5, 5′) of the diaphragm leaves (4, 4′) being parallel to the optical path at all times.

  • Apparatus for scrubbing gases
    Patent number: 4479816
    Abstract: In a disintegrator gas scrubber having a flat fan casing in which a stator bar cage is provided which consists of a plurality of concentric rings of bars extending parallel to the axis, and in which a rotor bar cage rotates which engages in the stator bar cage and likewise consists of a plurality of concentric rings of bars extending parallel to the axis, a cleansing liquid is injected by means of a cleansing liquid distributor means disposed on the rotor shaft of the rotor bar cage into the centrally aspired gas which is conveyed by the bars, the liquid being finely divided by those bars. A novel geometry and design of the stator bar cage and of the rotor bar cage are indicated to enlarge the purifying effect so as to embrace also the finest dusts of a particle size of less than 1 .mu.m and to permit separation of the same at optimum effectiveness without impairing the fan efficiency.

  • Electrostatic coating method
    Patent number: 4101687
    Abstract: Coatings of particulate materials are produced by the use of a highly ionized gas which, in turn, is employed to electrostatically charge the particles. The ionized gas is generated at location that is remote from the place at which it is passed through the particulate material, thus providing outstandingly safe operating conditions without sacrifice of the efficiency, uniformity or reliability of electrostatic charging.
