Abstract
355,187. Mercury-vapour rectifiers. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. Feb. 12, 1930, No. 4724. Convention date, March 15, 1929. Void [Published under Sect. 91 of the Acts]. [Class 39 (i).] Back-ignition in large mercury-vapour rectifiers is prevented by subdividing the cross - sectional area of the anode sleeves into two or more equal areas. The partitions may consist of crossed planes d<1>, d<2>, or of parallel planes, or concentric cylinders. The sleeves and partitions may be formed of a refractory metal and may be connected to, or insulated from, one another.
Improvements relating to the protection of electrical conductors and eqipment from the consequences of insulation failure, short circuits, and / or external damage
