Abstract

817,726. Automatic control systems for winders. BRITISH THOMSON-HOUSTON CO. Ltd. April 12, 1957 [April 20, 1956], No. 12174/56. Drawings to Specification. Class 38 (4). The description is identical with that of Specification 817,725 but the claims are directed to a system wherein inertia compensation is provided by the difference between the actual current through the main generator and its steady-state current.
