Abstract

438,104. Electric-transformer tanks with radiator elements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. - (Assignees of Allgemeine Elektricitõts Ges.; 2, Friedrich Karl-Ufer, Berlin) Feb. 6, 1934, No. 3875. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 8, 1934]. [Class 29] The radiator tubes b of the tank a are provided with diametrically opposite fins c<1> in a plane at right angles to the row of tubes or with double-threaded helical fins c<2>, so that the tubes may be placed close together. The helical fins have a pitch equal to the length of the straight part of the tubes and those of adjacent tubes fit into one another.
