Abstract
1,234,950. Electromagnetic switches; capacitors. MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT. 22 Nov., 1968 [23 Nov., 1967], No. 55563/68. Headings H1N and H1M. An electromagnetic current controlled device which may be an adjustable capacitance or a relay has reed armatures 5, 6 so spaced that when a coil 1 is energized, the free magnetic reed ends are moved toward each other but do not engage and on increase in energization the reed ends partly saturate and move further apart. The free ends of the reeds may be provided with non-magnetic co-operating contacts (Fig. 2, not shown), or each may be recessed at the end (Fig. 3) to co-operate with a respective fixed contact spring 9, 10, each adjustable by an eccentric 15, 16 on a threaded rod 11, 12.
