Title: Circuit arrangement with a number of frequency converters, particularly y-connected direct frequency converters
Inventor: WALDMANN HERMANN
IPC: H02M5/25
Filed: 1976-01-13
Granted: 1979-03-06
Abstract: Abstract of the Disclosure A circuit arrangement is disclosed having an odd number of Y-con-nected frequency converters.  The control units of the frequency converters are associated with current regulators, all of which are addressed by an additional common reference value.  In accord with the invention, the aforesaid reference value is derived by generating a difference voltage corresponding to the difference of the voltages at the neutral point of the frequency converter circuit and the neutral point of the load.  This difference voltage is then passed through a delay member whose time constant corresponds to the time constant of the load to develop the reference value.

Abstract: PHOTOCONDUCTOR CLEANING STATIONS                     Abstract A photoconductor member is cleaned by a rota-ting fiber brush.  The cleaned particles are knocked from the brush by a knock-off bar causing substantial wear on the brush.  To compensate for the wear, both the knock-off bar and the fiber brush are adjusted for maintaining cleansing contact between the photoconduc-tor member and the brush, plus the brush with the knock-off bar.  In a preferred form of the invention, the fiber brush also is an air impeller for entraining cleaned particles from the photoconductor drum into a disposal station which, by way of example, may contain a scavan-ging roll and an air filter.   The adjustments are such that the air impeller properties of the rotating brush are maintained throughout the life of the brush.

Abstract: ABSTRACT OF THE DISCLOSURE    Iodine and bromine are easily and quantitatively sepa-rated from the coolant of sodium-cooled reactors by passing a quantity of the sodium into a metal segregation vessel, and reducing the temperature of the vessel and coolant, whereupon the iodine and bromine segregates and adheres to the inner surface of the vessel where they remain after the coolant is separated from the vessel.  This method is useful for establishing the absence or the presence and possible severity of a failed fuel element in the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE:      An aquarium having a tank with a flat, built-in aerator mounted at the rear.  The aerator includes a housing having a number of narrow internal baffles arranged to form a zig-zag passageway for the upward flow of air into a space in the top of the housing.  The bottom of the zig-zag passage-way is disposed above a clear space in the lower part of the aerator housing, and each of the baffles runs from a first end at a first side edge to termination short of the opposite side edge of the housing.  The baffles extend alternately from the opposite sides of the aerator housing, and each slopes slightly upwardly from its first and to its other end within the housing.  The baffles are so arranged that each adjacent pair defines a transverse leg of the zig-zag passageway extending from one side of the aerator housing to the other and diverging vertically from a restricted entrance end to a far end where the entrance to the next higher leg of the passageway is situated.  The aerator housing has openings into the clear space in its lower part to admit aquarium water and compressed air.  The incoming air travels upwardly through the zig-zag passageway in turbulent contact with aquarium water in the passageway.  The aerator has a top outlet for the aerator water through which it is returned to the main body of water in the tank.
