Since the piezotransformer functions as a lamp electrode, as a ballast choke and as a transformer, the discharge lamp can be operated by means of a relatively simple and cheap ballast circuit.DANNERT, HORSTRAUSENBERGER, BERNDLEERS, DIETER
Electronic ballast with current measuring means for high-pressure discharge lamps the invention relates to an electronic ballast and operating procedures for hochdruckentladungslampen. in a strommessung, in particular for a current control, only schaltphasen a particular polarity of the flow are taken...

A cylindrical measurement chamber (1) surrounds a cylindrical, coaxial rotatable stirrer (2), by means of which the slurry is transported into the measurement chamber. The stirrer is provided with blades (2A) in the end which is furthest away from the pipe conduit (H). The blades on ...
a second choke produced by means of second magnetic-circuit elements each forming the chosen maximum air-gap and one or more intermediate chokes produced by means of the first and second magnetic-circuit elements to form the chosen intermediate air-gap(s) by combining the minimum and maximum air...
