Abstract: A method of removing liquid solvent from wood after pressure treatment with a preservative solution evaporates the excess solvent by mechanically circulating heated vapor of the same solvent used in the preservative solution past the wood in an autoclave. The autoclave is maintained at a constant pressure by transferring evaporated solvent to a condenser at a rate equal to the evaporation rate of solvent from the wood in the autoclave. The heat extracted from the condensing solvent vapor provides the heat to the circulating vapor in the autoclave for evaporating additional liquid solvent from the treated wood. Preferably, the vapor transferred from the autoclave is compressed before its delivery to the condenser so that the heat needed for evaporation in the autoclave can be obtained by simple heat transfer of the excess heat from the condenser.

Abstract translation: 用防腐剂溶液进行压力处理后从木材中除去液体溶剂的方法通过机械循环使用在防腐剂溶液中的相同溶剂的热蒸气在高压釜中通过木材蒸发多余的溶剂。 通过将蒸发的溶剂以等于高压釜中的木材的溶剂的蒸发速率的速率将蒸发的溶剂转移到冷凝器，将高压釜保持在恒定压力。 从冷凝溶剂蒸气提取的热量向高压釜中的循环蒸气提供热量，用于从经处理的木材蒸发附加的液体溶剂。 优选地，从高压釜转移的蒸汽在其输送到冷凝器之前被压缩，使得通过从冷凝器的多余热量的简单传热可以获得在高压釜中蒸发所需的热量。

Abstract: Cover for a cylinder-shaped pressure container such as a vacuum impregnation container or an autoclave which at the mouth edge has members for holding a tight fitting closure member against the mouth edge which members contrary to previously known and complicated members can be manufactured by means of generally known working processes and machine tools. The mouth edge of the container (1) and the closure member (3) both have a radially outwards directed annular flange (2,4) which flanges have cooperating contact faces (5) and each a sloping surface, whereby the width of the two flange members (2,4) is decreasing towards the outer edge. The cover further comprises a retaining ring (6) which is placed close to the flange members (2,4) and which is ended up by two free ends (8). The retaining ring (6) has a slot (7) which is open towards the center and corresponding to the cross section of the flange members (2,4), and the circumference of the retaining ring (6) is similar to the outer circumference of the flanges (2,4) so that the free ends of the ring (6) can be pulled towards each other, when the flange members (2,4) are assumed in the slot (7) of the ring (6). The free ends (8) of the retaining ring (6) can be connected to driving means (9) of a hydraulic type for the closing of the retaining ring (6) around the flange members (2,4).

Abstract: The apparatus and the method for impregnation of wood. The apparatus has a closable tank which defines our interior space and comprises a vessel with at least one door for closing the vessel to isolate the interior space from the exterior of the tank. The tank being capable of supporting a pressure difference between the interior space and the exterior of the tank. The apparatus contains a device for supplying liquid to and receiving from the interior space of the tank, a device for establishing a pressure difference between the interior space and the exterior of the tank, a structure which is disposed in the interior space for holding wood to be treated and a structure supporting the holding structure to permit rotation of the holding structure about a non-vertical axis while holding wood to be treated.
