Abstract

771,920. Supplying electric fences; charging and discharging condensers. WOLSELEY ENGINEERING, Ltd., and DRAKE, R. S. Nov. 29, 1954 [Jan. 16, 1954], No. 1356/54. Class 38 (4). An electric fence 8 is energized by a pulse transformer 1, the primary winding 2 of which is excited by the periodic discharge of a condenser 3 permanently on charge over resistors 12, 13 from a reservoir condenser 11 which is charged over a dry rectifier 10 from A.C. mains 9. The periodic discharge of condenser 3 is effected by a mercury switch 14 which is rocked by a mains-driven synchronous motor 18 so as periodically to connect the condenser across the transformer. The switch is of the kind having a mercury pool 17 which when, and only when, the switch is oscillated from side to side, elongates sufficiently to effect momentary bridging of its contacts 15, 16.
