Abstract
A housing (2) contains a pump (4) driven by a motor (6) and connected to a shallow trough (10) by a control valve (20). Above the trough is a silk screen supported by a plastics grid over which are two corrugated flaps (44, 46) and above these is a liquid reservoir (40) with an inflatable seal (42) around its base. The reservoir is tilted to place the documents on the silk screen, then lowered, the seal inflated, and the flaps lowered to hold the document. The reservoir is filled with water and the restoring mixture added, and the pump switched on. After treatment, the flaps are raised, and the corrugations prevent liquid running or dripping onto the documents, but causes it to drain to the sides. The pump is shut off and the documents removed.
