Abstract

1,159,306. Discharge lamps. J. W. HARRISON and R. N. FOXGORD. 24 April, 1967 [2 Aug., 1966], No. 18854/67. Heading H1D. [Also in Division H5] In fluid sterilization apparatus (see Division H5) comprising a chamber through which fluid to be sterilized passes, having a lamp projecting into the chamber and being adapted to emit ultra-violet rays to irradiate the fluid, the lamp projecting through a wall of the chamber, a fluid tight sealing means is fitted between the wall and the lamp and comprises a mouldedin-place seal of resilent material which adheres to the surface of the lamp. The preferred material is silicone rubber. Preferably as shown the lamp is tubular, the chamber 11 being elongated with the lamp 12 supported centrally in it by the interaction of mouldedin-place gaskets 48 and annular elements 49, 52 which by means of screws 53 are tightly clamped on the gasket. In alternative sealing arrangements, Figs. 9 to 11 (not shown), the moulded-on seal is provided on its face facing away from the chamber 11 with an apertured disc bonded to it. A locating means comprising a removable retaining ring is provided in a groove in the housing to locate the lamp. The seal may have concave or cup-shaped inner surfaces so that the pressure of the fluid in the chamber tends to force the seal against the wall. Alternative locating means (Fig. 10) comprises a sleeve which co-operates with a threaded cap 54 to locate the tube 12. An 0 ring may be fitted in to a groove around the sleeve and disc to complete the seal. In Fig. 11, the disc is replaced by a cylindrical member into a central orifice in which the moulded-in-place seal fits. The cylindrical member is positioned by means of a sleeve and threaded cap and sealed by an 0 ring as in the previous alternative.
