    摘要： A resistance heating element comprises a fiber-reinforced thermoplastic material having 1-60% by weight of glass fibers and having 1-20, preferably 5-15% by weight of steel fibers. The heating element can be prepared from thermoplastic granules which are filled with glass fibers and steel fibers and which have been obtained by melt pultrusion of continuous fiber strands and cutting to granule length.

    摘要： An electronic ballast (10), for a gas discharge lamp (18), comprises a constant current source (14) and a switch (16). A transformer (60), for use in an igniter (90) for a gas discharge lamp (18, 40), comprises a core (62) which has interconnected legs (64, 66, 68), a first secondary winding (70) around a first leg (64), a second secondary winding (72) around a second leg (66), and a primary winding (74) around a third leg (66). An igniter (90) for a gas discharge lamp (18, 40) comprises a transformer (60) as described above and a drive circuit (92) for driving the primary winding (74). The first and second secondary windings (70, 72) of the transformer (60) are electically couplable in series with a discharge lamp (18, 40)

    摘要： A current overload tripping device having a time-delayed leading tripping action during uneven loading of the phases of a multiphase circuit. The tripping device includes a current pickup for each phase wherein the current pickup members are connected in series with one another and with an electromagnetic converter. Each of the current pickup members comprises a winding surrounding a magnet yoke of an electromagnetic tripping device of each phase and the electromagnetic converter comprises a temperature/time-dependent device operating to provide a time-delayed tripping signal.
