<p>531,097. Asymmetrically-conducting resistances. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., CUBITT, R. H., and THOMPSON, L. E. June 27, 1939. [Class 37] A cooling plate, fitted between rectifier elements in an assembly, is also shaped to act as spacers. Thus, a cooling fin may be cast with a central boss or, as shown, a boss 2 may be pressed out of a thin sheet. In this case the hole 3 for the assembling rod may be dished inwardly. In a further modification, a series of bosses are pressed out around the central hole.</p> |
