Magnetic amplifiers

Figure 8-5 shows the main circuit diagram of a potential control rectifier provided with magnetic amplifiers (transducers). The chosen potential is set at the nominal value with a potentiometer. The actual potential is compared with this value, which corresponds to the voltage between a reference electrode and the protected object. [Pg.234]

In 1919, he made history with yet another of his inventions when his multiple-tuned antenna, antistatic receiver, and magnetic amplifier were used to transmit the first two-way radio conversation. This great event took place 900 miles out to sea, between the Trans-Atlantic Marconi Company station at New Brunswick and the steamship George Washington, with President Woodrow Wilson on board as a witness. [Pg.65]

Barium titanate has many important commercial apphcations. It has both ferroelectric and piezoelectric properties. Also, it has a very high dielectric constant (about 1,000 times that of water). The compound has five crystalline modifications, each of which is stable over a particular temperature range. Ceramic bodies of barium titanate find wide applications in dielectric amplifiers, magnetic amplifiers, and capacitors. These storage devices are used in digital calculators, radio and television sets, ultrasonic apparatus, crystal microphone and telephone, sonar equipment, and many other electronic devices. [Pg.94]

FERROELECTRIC MATERIALS. The dielectric analogs of ferromagnetic materials. Their uses parallel those of ferromagnetic materials in such applications as magnetostriclive transducers, magnetic amplifiers, and magnetic information storage devices. Rochelle salt was the first ferroelectric material to be discovered and the barium titanale ceramics arc materials of this type... [Pg.612]

Magnetic thin films of nickel-iron (usually deposited at an 80 20 composition by weight) exhibit a number of unusual properties, which have led to many experimental and theoretical studies, as well as to impoitant applications in binary storage and switching, magnetic amplifiers, and magneto-optical Kerr-effect displays,... [Pg.1613]

The 16 magnet amplifiers (two for each magnet) are all connected in parallel to the sigma bus. If all 16 amplifiers and all eight magnets were identical in adjustment and operation, all safety rods might be expected to drop strictly simultaneously as the sigma bus potential rises past some critical value. What will actually happen, of course, is that one or several... [Pg.246]

Sigma - sigma amplifiers feed safety- signals to the. sigma bus, which thus combines these signals and feeds them to the magnet amplifiers, adl in parallel. [Pg.283]

Fig. 123.1 The mean radius of earth is about 3,960 mi (6,373 km). By contrast the radius of the georeactor is only about 6 mi (10 km), although there is much uncertainty in that estimate. The georeactor, thought to reside within the inner core at the center of earth, is comparably simple in stmcture. The georeactor sub-core consists of the actinide fuel, the uranium and heaver fissionable elements, such as plutonium, formed by the fission process. The surrounding sub-sheU, which is thought to be liquid or a slurry, consists of radioactive decay products and fission products. Heat produced by nuclear fission in the sub-core, causes convection in the sub-shell which will interact with the CotioUs forces produced by planetary rotation and act like a dynamo, a magnetic amplifier, generating the geomagnetic field (Herndon, 2007,2009).

The hysteresis characteristics of soft magnetic materials may be enhanced for some applications by an appropriate heat treatment in the presence of a magnetic field. Using such a technique, a square hysteresis loop may be produced, which is desirable in some magnetic amplifier and pulse transformer applications. In addition, soft magnetic materials are used in generators, motors, dynamos, and switching circuits. [Pg.822]

To control the servo-drive of the automatic regulator rod, the magnetic amplifier is used. [Pg.129]
