778,600. Vapour diffusing devices. AIRKEM, Inc. Feb. 21, 1956 [March 18, 1955], No. 5315/56. Class 81(1) A vapour diffusing device for air treating gel in cylindrical slug form comprises a storage chamber 13 having a length and width closely conforming to the length and diameter of a predetermined sized cylindrical gel slug 15 when disposed with its axis horizontally of the chamber, supporting means for the chamber providing a volatilization zone 14 below the chamber, and means forming a restricted passage 25 between the volatilization zone and the chamber, the opening provided by the restricted passage being substantially less than the diameter of a fresh gel slug to thereby support the gel slug within the chamber while exposing a portion of the cylindrical surface of the gel slug for evaporation of volatilizable material therefrom. As shown the vapour diffuser comprises a base 10 provided with grooves 16 for receiving in snap engagement a flange 17 extending around the lower end of a body portion 11 and a telescoping closure part 12 which together form the upper storage chamber 13 and the lower volatilization chamber 14 for cylindrical bodies of air treating gels 15 which are supported one above the other by ribs 24 forming a restricted passage 25 through which part of the lower gel is exposed and vaporizes until it has wasted sufficiently to fall through into the volatilization chamber 14 (as shown at 15<SP>11</SP>) when another takes its place. Apertures 26 are provided in opposed longitudinal walls of the lower part of the body 11 and through which by vertical adjustment of the closure 12 the rate of volatilization of the gels may be regulated, a visual indicator marked on the end of the closure 12 serving to indicate the extent to which the apertures are open.
