Abstract
1,265,644. Tuned electromagnetic relays. COMPAGNI DES COMPTEURS. 6 Feb., 1970 [18 Feb., 1969], No. 5889/70. Heading H1N. An electromagnetic resonance relay having a vibratory member 12 fixed as a cantilever relative to a magnetic frame 1 with a magnetic extension 22 of the member 12 extending into an airgap of the magnetic frame 1 normal to the pole faces 5, 6 thereof and also extending parallel to a pole face 10 of a permanent magnet 9 arranged on one pole of the frame 1. The frame 1 includes a core 8 for a coil 3 which is in series with a capacitor 4 and the member 12 is mounted between two elements 13, 14 which are clamped together, by means not shown, along an axis A-B and are each provided with four indentations 19 which align with eight similar indentations 20 on the member 12 to receive eight steel balls 21. Screws 15, 16 in the block 13 secure it to the frame 1. In an alternative arrangement (Fig. 3, not shown) the member 12 is on the side of the limb 7 remote from the coil 3 and the magnet 9 is on the end of the limb 7. The member 12 has a further extension 25 provided with a pawl 26 for operation of a ratchet-wheel or rubberized wheel. Alternatively, the member 12 can influence a piezo-electric or inductive device.
