The force [F.sub.0] acts in the alternating-current relay when the outer magnetic flux is absent ([F.sub.0] = [F.sub.n], when [[PSI].sub.exm] [right arrow] 0 and [[PSI]] [right arrow] 0).
Tesla's 700-plus patents include the Tesla coil transformer, the rotating magnetic field, the fluorescent light, the loudspeaker, alternating-current power transmission, wireless communication, and radio.
Older alternating-current (AC) recorders provide reliable tracings, but those that were designed with a short time constant can produce tracings that appear to represent nystagmus, but which are actually artifact.
Alternating-current vector drives, which help ac motors achieve rated torque at speeds near zero rpm, will capture part of the market dominated by dc drives and motors.
Though spokesmen for some utilities have irresponsibly attempted to suggest that if worse comes to worse people will just have to endure the risk of being subject to the harmful effects of alternating-current magnetic fields or else forgo the advantages of electric power, there are many relatively inexpensive measures that can be taken now to mitigate the problem.
Using some fancy statistical footwork, the reserachers separated out the direct-current (DC) component due to core currents from the tangle of alternating-current (AC) signals arising from a variety of sources, such as the erratic flow of ions in the ionosphere, that induce currents in the earth.
Their topics include the theoretical background and mode of action of gas plasma sterilization, nitrogen gas plasma for remote sterilization and clarification of sterilization, fungal and mycotoxin inactivation by cold plasma sterilization, disinfecting seed-borne fungi and bacteria by plasma with alternating-current high-voltage discharge, and misinterpreting microbiological data on gas plasma sterilization: avoiding the pitfalls.
Among their topics are chaos theory and electrical drive systems, chaos in alternating-current and direct-current systems, stabilizing and stimulating chaos, and applying chaotic modulation and motion.
