Abstract
806,666. Capless elecric lamps. BRITISH THOMSON-HOUSTON CO. Ltd. June 21, 1957 [July 16, 1956], No. 21922/56. Addition to 797,441. Class 39(2) In a modification of the capless electric lamps described in the parent Specification the leading-in wires 2 that are embedded in the flattened glass pinch 4 which seals and closes the end of the bulb 1 have their outer ends 5 bent back against a flattened surface or surfaces of the pinch in order to provide electrical contacts, the thickness of the leading-in wires being such that the contact portions are firmly supported against the flattened surface or surfaces from the points where they emerge from the pinch. The outer ends 5 of the two leading-in wires may lie either upon opposite side faces of the flattened pinch or upon the same side face; alternatively they may be bent back upon the opposite end faces of the pinch, as shown in Fig. 3. The extremities of the wires are bent over into horizontal notches 7 formed in the side and end faces of the pinch during the piching operation. To increase the contact area of the external portions of the leading-in wires they may be flattened, as at 5a, Fig. 2. Lateral movement of the lamp in a holder may be restricted by providing the faces or ends of the pinch with notches or protuberances which extend perpendicular to the horizontal notches 7 and co-operate with engaging means in the holder. The leading-in wires may consist of coppersheathed nickel iron having a diameter greater than 0.012 inch
