2015-3-7 where L inductance in microhenrys ( H) N the number of turns. The A L factor is a function of the properties of the core materials and is found in Table 4-1; the units are microhenrys per 100 turns ( H/100 turns). In my case, I se-lected an L-57-6, which covers the correct frequency range and has an A L value of 115 H/100 turns.
Experimental TRC of magnesium was carried out for the first time in the 1980s by Dow Chemical, who used a proprietary molten magnesium handling system, coupled with a Hunter caster originally designed for aluminum alloys (horizontal configuration) to produce 200 kg coiled magnesium strip, with a thickness of 6–7 mm and width of 610 mm, at a ...
A toroidal electrical transformer having a low voltage coil, a high voltage coil and an annular magnetic core is disclosed. The preferred low voltage and high voltage coils are each continuous in substantial part over their length and form an arcuate elongated passage therethrough.

In the early 1980's, Johnson Bros. produced Z-Channels for building sized parabolic satellite antenna receiving station discs, used around the world. They were made from 6061-T4 age hardening Aluminum. Two sizes of Purlins had to be bent with a sweep in the hard direction, for 16 different radii, that made up the frame of the dish.

2014-4-1 2. Shape memory alloy overview. SMAs are a group of metallic alloys that can return to their original form (shape or size) when subjected to a memorisation process between two transformation phases, which is temperature or magnetic field dependent. This transformation phenomenon is known as the shape memory effect (SME).
