<p>503,335. Asymmetrically-conducting resistances. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and WILLIAMS, A. L. Oct. 4, 1937, No. 26815. [Class 37] To prevent the soft metal washers 3, used for connecting adjacent units 1, 2 in a metal rectifier, from spreading under pressure and so causing a short circuit, a disc or washer 6 of insulating material is placed at the edge of the washers 3. In the example the insulator 6 is on the inner edge filling the comparatively large central aperture of each soft metal washer. In a modification the insulator forms an annulus around the metal washer, which, in this instance is of smaller diameter than the working plates.</p> |
