Abstract

151,661. Vecchis, I. de. March 3, 1919. Wood, treating with liquids.-Wood is treated with a solution of double sulphates or chlorides of copper, zinc, and magnesium with ammonium used simultaneously, preferably in conjunction with free alkali, to enable it to resist parasites and to increase its strength. The wood is placed in a closed container in which a vacuum is produced, and may be subjected to heat to facilitate the removal of the sap. The treating-solution is then allowed to be sucked into the container, and is subsequently pumped in until a pressure of 8- 14 atmospheres is obtained. After the necessary time has elapsed the wood may be removed or may again be subjected to a vacuum in a hot or cold state, prior to allowing it to dry in the open air. Specifications 5893/00 and 9989/00, [both in Class 145, Wood &c.], are referred to.
