Abstract
59 2,626. Metal vapour lamps. FRENCH, E. A. H. Jan. 5, 1945, No. 557. [Class 39 (i)] A high-pressure mercury-vapour lamp comprises a cylindrical stainless steel or porcelain arc chamber A in which electrodes F and G are detachably mounted, and a circular aperture is covered by a removable window B of thick quartz, a vacuum-tight joint being effected by means of a pressure gasket E, a clamping ring C and bolts D. The electrodes are rods of carbon or tungsten ; one, G, is held in a tapered ferrule I screwed in a collar K integral with the wall of the chamber, a terminal T extending through the chamber acting as a current lead. The other electrode F is held in a tapered ferrule H. screwed into a collar J which lies in a recess in a block M of porcelain or other insulating material. This block is fitted into an opening in the wall of the chamber, a vacuum-tight joint being made by bolts N and a pressure gasket R. The collar J has an extension L which passes through the block M and forms a terminal Q for the other current lead, the gasket P and nut O forming a seal. The arc chamber has a pair of stainless steel tubes S for connection with an evacuating system which may include a vacuum pump, a mercury boiler and a condenser.
