Abstract: A replenisher supply device for photosensitive planographic printing plate processing apparatus, the supply device being arranged independently of each photosensitive planographic printing plate processing apparatus, which includes: a unit for opening a seal for a processing replenisher contained in each of containers; a tank for receiving the processing replenisher from the container; sensors for detecting the levels of the processing replenisher in each tank; and piping for supplying the processing replenisher from each tank to sucking inlets of processing replenisher supply pumps which are arranged in each photosensitive planographic printing plate processing apparatus body. Accordingly, the replenishers and water can be supplied to a plurality of photosensitive planographic printing plate processing apparatus by a reduced number of replenisher supply devices.

Abstract: A method for inhibiting corrosion of metal by contacting the metal with a volatile alkyl ester of an amino acid. The invention also provides compositions containing these alkyl esters of amino acids as an active anti-corrosion inhibitor. These compositions may be fluid or semi-fluid compositions exemplified by oil-base compositions. The compositions may also be porous materials such as zeolite, silica gel, paper board, kraft paper, cloth, etc.
