Method of impregnating wood in order to protect it against fungal decay. Conventionally wood has been treated with copper-chromium-arsenic preservatives in a one stage treatment, e.g. by impregnating the wood with a solution of these compounds. The chromium component serves to fix the copper in the wood to prevent it from leaching out. It has now been found that a two-stage treatment in which (1) ...

The device for attaching and tensioning a blanket on a cylinder of a printer may be protected against mishandling and inadvertant opening.
