Abstract: A lamp (50) has a lamp envelope (10) having a body (12) with a bottom (14) having a lead-in accepting channel (18); a seat (22) formed with the bottom (14) adjacent one of the lead-in accepting channels; a light source capsule (51) having two electrical lead-ins (52, 54) extending therefrom and through the lead-in accepting channel (18; and an electrical contact (24) having a first depending leg (26), an intermediate transverse portion (28) including a seat engager (30) adapted to cooperate with the seat (22), and a projecting leg (32) extending away from the intermediate transverse portion (28) and along a side (34) of the bottom (16), the first depending leg (26) being in mechanical and electrical contact with one of the lead-ins (54).

Abstract: A dispenser (10) for a volatilizable material has a first member (14) that is substantially cup-shaped with a given diameter (X) and with a given depth (Z) and having a first peripheral flange (16) having a first diameter (D). A second member (18) has a second peripheral flange (20) with a second diameter (D2) greater than the given diameter (X). The first peripheral flange (16) and the second peripheral flange (20) are in intimate contact thereby defining a volatilizable material chamber (22) between the bottom (24) of the second member (18) and the bottom (26) of the first cup-shaped member (14). A volatilizable material (12) such as liquid mercury is placed in the chamber; and a hermetic seal (28) is formed between the first and second flanges. When installed in a fluorescent lamp the volatilizable material is released by heating the dispenser with RF current. The material is released when the vapor pressure within the dispenser reaches about 20 atmospheres.
