  • Bioreactor
    Patent number: 9918463
    Abstract: The invention relates to a bioreactor for charging the outside and the interior of a hollow element (1) or hollow element framework with a liquid, having a housing (2) accommodating the liquid, forming a liquid surface, and a rotation device (3) arranged within the housing (2) and receiving the hollow element (1), which rotation device (3) is for rotating the hollow element (1) about the longitudinal axis (4) thereof in the region of the liquid surface. In known bioreactors of this type, the interior of the hollow element must be flushed with a special device, and so here also a liquid exchange takes place.
    Type: Grant

  • Arrangement for measuring the field angle of a magnetic field as a function of axial position within a magnet bore tube
    Patent number: 5228351
    Abstract: An arrangement for measuring the field angle of a magnetic field as a function of axial position within a magnet bore tube of a magnet such as is used with the Superconducting Super Collider (SSC). The arrangement includes a magnetic field alignment gauge that is carried through the magnet bore tube by a positioning shuttle in predetermined increments. The positioning shuttle includes an extensible body assembly which is actuated by an internal piston arrangement. A pair of spaced inflatable cuffs are carried by the body assembly and are selectively actuated in cooperation with pressurizing of the piston to selectively drive the positioning shuttle in an axial direction. Control of the shuttle is provided by programmed electronic computer means located exteriorly of the bore tube and which controls valves provided pressurized fluid to the inflatable cuss and the piston arrangement.
