Abstract

441,676. Electromagnets. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 9, 1935, No. 25058. Convention date, Sept. 8, 1934. [Class 35] A rail-brake magnet has a coil box with a core k and side walls m in one piece and of substantially rectangular or H-shaped crosssection. Check pieces ware in direct contact with the side walls m and carry the brake-shoes c. The walls m and check pieces w may be in one piece. The coil p is embedded in a mass a of quartz sand with a binder and is sealed by a plate b secured by pins t. Specifications 23885/04 and 865/07, [both in Class 103], are referred to.
