Abstract: This invention relates to a 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 copper and fixative agent are impregnated without arsenic and (2) the arsenic is impregnated separately, improves resistance of the wood to soft-rot fungi. The invention is particularly useful for treating hardwoods.

Abstract: A method for applying a blown polyurethane coating to carpeting or other sheet material. The method includes the step of adding a filler to the polyurethane components to assure that the liquid does not unduly penetrate porous goods. The mixed polyurethane components are then placed in a puddle on the sheet material and leveled to a uniform coating. Steam is passed through the sheet material and the coating to initiate the reaction of the components. The steam also adds water to the coating, so the formulation is such that additional water is needed, and the needed water is added by the steaming. After the polyurethane has completed blowing, and before the polyurethane has cured beyond its plastic state, the foam may be compressed to decrease the thickness. A second sheet of material can be placed over the polyurethane to prevent the polyurethane from adhering to the compressing roller.

A moving web is supported on a backing surface. Two stationary and pliant smoothing films are positioned one adjacent each surface of the web, including the web surface which is supported by the backing surface.

The relative position of the backing surface and the pressure generating means determines the length of coincidence of the moving web, coating liquid, stationary smoothing films and pressure generating means.

The surface of the cable is then heated to melt the binder powder and cause the electrically conductive powder to yet more firmly adhere to the surface of the cable. The cable is then cooled and wound.
