Title: Immediate frequency converter
Inventor: BUKHSHTABER ELIAZAR YA
IPC: H02M5/27
Filed: 1992-05-12
Granted: 1996-09-10
Abstract: FIELD: electric engineering. SUBSTANCE: device may be used for frequency control of three-phase electric motors without brushes, in particular by induction motors which have short-circuited rotors and are supplied from power supplies or three-phase lines with zero line. Immediate frequency converter with natural commutation has 18 main connecting gates and six additional controlled gates. All gates used in design of converter are thyristors which are locked when their current downs to zero level. Common point of additional controlled gates is connected to zero line. This results in possibility to decrease ripple of phase currents and so to decrease lower limit of regulation of output voltage frequency f 2  as well as to increase upper limit of regulation range of frequency f 2  to level which are close to power supply frequency f 1 . When f 2 >0,8f 1  and frequency f r  further grows, shape and symmetry of output voltage goes closer to shape and symmetry of power supply voltage. This results in possibility of effective use of converter for frequency control of electric drives which load moment is increased as square, cube or as greater order function when rotation frequency is increased. Control unit with this converter provides separate control of gates, phase regulation of output voltage and inverter mode for electric braking of induction motors as well as smoothing ripples of phase currents and equalization of integral values of half- waves for different duration. EFFECT: increased functional capabilities, increased field of application. 2 cl, 4 dwg

Title: Cleaning method for ultra-violet waste water treatment reactor
Inventor: ADAMS JOERG
IPC: C02F1/32
Filed: 1996-02-14
Granted: 1996-12-12
Abstract: Waste water is treated by exposure to UV light in a reactor which is periodically cleaned. During the process the intensity of UV light is continually monitored within the reactor, so that when the value monitored falls below a given lower threshold, a sensor triggers a valve which closes off the reactor from the water treatment process, draining water from the reactor, and filling the reactor with air. The reactor is then flushed with a cleaning soln. at a given rate and at intervals defined by the residues on the reactor walls. The flushing continues until the UV light detector within the reactor indicates that the UV light reaching the inner part of the reactor is adequate for the treatment process. The positions of the fluid valves are then changed to discharge the cleaning fluid, admit air, rinse with fresh water and resume the cleaning process.
