Abstract
Abstract A self-contained disposable package including a container of diazo copy developer liquid and an ammonia vapor absorber canister is disclosed for use with diazo type copy machines. The container of developer liquid and an absorber canister are adapted to be readily hooked into the supply and exhaust lines of the copy machine developer chamber and to the exhaust line of a machine degassing chamber. The absorber canister includes a quantity of ammonia vapor absorber material such as a mixture of excelsior and activated carbon, both treated with phosphoric acid, into which is extended a flow tube adapted to be connected to the degassing exhaust chamber with the exhaust flow directed to emanate from the lower region of the canister and flow upwardly through the absorber material and thence out through openings in a top cap. The quantity of developer and absorber is correlated such that the entire package may be replaced as soon as the developer liquid becomes exhausted.
