Abstract

691,207. Electromagnetic relays. WESTERN ELECTRIC CO., Inc. Oct. 3, 1950 [Oct. 5, 1949], No. 24132/50. Class 38 (v) The armature 5 of a polarized relay is fixed to a stem 7 and extends upwards from a mercury pool 21 so that its upper end lies between two contacts 10, 11 on pole pieces 8, 9 magnetised with opposite polarity by permanent magnets 12, 13; grooves 5a on the surface of the armature form capillary channels so that mercury can reach the contact surfaces: The fixed contacts 10, 11 are the ends of wires fixed to pole pieces 8, 9 which may be coated with chromium oxide so that they cannot be wet by the mercury. Alternatively the pole pieces may be shaped so as to drain off any mercury Fig. 2 (not shown). The magnetic circuits from the magnets 12, 13 are completed by magnetic members 15, 16 whence the flux proceeds through insulation 17 to an outer magnetic casing 27 and thence back through the insulation to a magnetic member 23 fixed to the stem 7. The operating coil 18 of the relay surrounds the sealed tube 6 containing the armature &c.
