Title: Regulated eddy current drive
Inventor: MEYL KONSTANTIN DIPL ING
IPC: H02P29/00
Filed: 1981-01-17
Abstract: A regulated eddy current drive, which is produced in the range from 1 kW to 15 kW, can be overloaded by a factor of approximately two and can drive or brake the load in fourth quadrant operation. It has a significantly improved efficiency and is nonetheless cost-effective and maintenance-free. The drive obtains these favourable characteristics as a result of its arrangement according to the invention, consisting of a reversible-pole asynchronous motor with contactor control, an eddy-current coupling to a tachogenerator, a matched regulator device and control logic. A speed which can be regulated continuously is obtained via the adjustable slip of the coupling from the speed of the asynchronous motor, which can be set in steps. The eddy-current coupling of the Meyl + Ziesel type provides the damping characteristics required during motor switching, is likewise maintenance-free and has an amplifying effect, as a result of which only very small control paths and hence small actuating and regulation devices are necessary. According to the invention, as a result of automatic switching of the contactors, the control logic ensures limited-slip operation of the coupling, with losses which are as small as possible. Applications exist as a winch or capstan drive, particularly in conveyance technology, and for lifts. <IMAGE>

Title: Method for determining indicator running times in retinal blood vessels
Inventor: VILSER WALTHARD DR
IPC: A61B3/12
Filed: 1982-06-25
Abstract: The method for determining indicator running times in retinal blood vessels can be used besides determination of indicator running times in connection with the measurement of vessel diameters and on use of at least two measurement surfaces for the determination of the volume blood flow. It is the object of the invention to cover as many measuring points as possible with the smallest possible measurement inaccuracy and during a dyestuff passage. The essence of the invention is the fact that a control and measurement signal is obtained on each circular relative movement between measurement surface and retinal image, that the control signal is used for recording of the measured signal in the correct vessel and permits recording only if the measured signal surface and the vessel overlap. It is furthermore used for forming a difference signal between the measured signal values on the vessel and in the immediate vicinity thereof. The zero pass of the difference signal is used as the point of appearance of the indicator. The measurement method proposed can be used for all optically accessible streams identified by an indicator.
