Abstract
718,884. Discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 12, 1953 [Jan. 15, 1952], No. 858/53. Class 39(1) Connection to a conduct ive strip or coating 7 oi the inside of a discharge tube is made by a meta tape 8, the end of which i split into adjacent fingers as at 10, 11, 12, at least one of which lies in direct con tact with the coating, while another is secured by ad hesive. The example shown is a fluorescent discharge lamp, one electrode of which is connected to a starting strip 7 by a ferro-chromium tape 8.
