Patent number: 5627428Abstract: To reliably and simply connect one end of a double-ended discharge vessel it (1) and a surrounding envelope (11) to a base (8), the base has a base sleeve (8a) which encloses a base holder portion (8b). The envelope (11) is melt-connected to the discharge vessel unit (1), for example just beyond pinch seals formed thereon, and is additionally formed with an extension (11a) which is, in turn, melt-connected to the holder portion (8b) of the base. Preferably, a metallic cuff is placed within the holder portion so that, by high-frequency inductive heating, a reception region (8d) of the holder portion can melt and tightly grip the extension (11a) of the envelope. To improve adhesion, the surface of the extension region (11a) may be ribbed, knurled or otherwise, slightly deformed.Type: GrantFiled: June 27, 1995Date of Patent: May 6, 1997Assignee: Patent-Treuhand-Gesellschaft F.

Patent number: 5495138Abstract: To provide a strain relief in a base for an electric lamp, adapted for coction to an external electrical energy source by at least one connection cable (6a, 6b) extending through and into the base, the base (2) is formed with a strain relief arrangement which includes a resilient sleeve (11) having an inner wall surrounding the at least one connection cable and, within the base bottom portion (9, 9'), a sleeve reception structure (9a) positioned inwardly of the bottom of the base, which includes a sleeve reception bore (10a, 10b) receiving and surrounding the resilient sleeve (11a, 11b) and exerting circumferentially uniformly, radially inwardly directed forces on the resilient sleeve. This decreases the diameter of the sleeve so that the inner wall thereof engages, clamps and squeezes the deformable insulation of the at least one connection cable and, also, can interengage or interlock therewith. The bottom portion (9) and the top portion (7) of the base are snapped together.Type: GrantFiled: September 7, 1994Date of Patent: February 27, 1996Assignee: Patent-Treuhand-Gesellschaft F.
