Abstract

471,278. Discharge lamps. FELTEN & GUILLEAUME CARLSWERK AKT.-GES. May 13, 1936, No. 13585. Convention date, May 13, 1935. [Class 39 (i)] [Also in Group XXXVI] A high-voltage indicator comprises a tube 1 of insulating material which has a screwed head 2 carrying a discharge tube 3, the latter consisting of a glass bowl 4 and an electrode 6, and being provided with a drop of mercury 7 in the bowl 4 which, on shaking the tube, charges the walls by friction so that the tube lights up if undamaged, The interior of the tube 1 has a conductive covering 8 for increasing the capacitative coupling and a lead 9 is used for placing the indicator on the part of the plant to be tested.
