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.
A self-contained disposable package for a diazo copy machine of the type including a developer chamber supplied with a development vapor and degassing means for drawing off the ammonia vapors emanating from developed copy, the package comprising:
A method of providing a supply of developer liquid and ammonia absorber material for a diazo copy machine of the type including a development chamber through which is directed an air flow containing water vapor and ammonia vapor, directing the supply and exhaust flow through supply and exhaust lines, respectively, and further including degassing means for drawing off air flow at regions adjacent developed diazo copy material in order to produce an outflow of ammonia vapor, the method comprising the steps of:
The method according to claim 13 wherein in said step of packaging is performed by correlating the quantity of development liquid with the quantity of absorber material such that upon exhaustion of said development liquid, said absorber material is saturated or exhausted.
