Abstract

1389291 Drying gases TELECOMMUNICATIONS INDUSTRIES INC 18 April 1972 [22 April 1971] 17937/72 Heading BIT [Also in Division C1] An ozone-containing gas entering through inlet 74a is stabilised by mixing it with a gas (e.g. air or oxygen) entering through inlets 75, 76, and dried by passing it through felt filters 69, 70 and filter 72 comprising cellulose sheet wound on perforated core 73. The dried and stabilised gas is discharged through outlet 78 to an ozone generator (not shown) supplying a water purifying chamber (not shown) from which the exhausted ozonecontaining gas is supplied to inlet 74a.
