Abstract
236,582. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). July 4, 1924, [Convention date]. Induction motor meters. - The driving- magnet is so arranged that the potential and current coils can be readily removed. The core of the potential magnet has a leg a pivoted at d and carrying the series magnet c and a closing-piece b. By swinging the leg a to the position shown and removing a retaining-piece e, the potential coil f may be removed and replaced by a new coil. The piece e is then replaced, the leg a swung back to its normal position, and the centre limb g, retaining-piece e, and closing-piece b are held together by two screws h, h<1>.
