Two different gases, which contain sulfur compounds and Co2, are desulfurized with a physically acting solvent. The first gas is treated with the solvent in a first scrubbing zone, in which the sulfur compounds, particularly H2S and COS, are substantially completely removed and part of the Co2 content in the gas is dissolved. At least part of the laden solvent leaving the first scrubbing zone is f...

The invention provides a ski wax material in the form of a sheet (10) comprising a sheet substrate (12) composed of heat-resistant fibres and heat-meltable solid wax (14) impregnated in the sheet substrate and/or adhered to the surface of the sheet substrate.

Sputtered coatings of gradient thicknesses are produced by employing a foraminous mask between the cathode and the substrate. The size of openings in the foraminous mask may be varied in different areas to provide versatility in controlling the gradient patterns. The invention is particularly suitable for producing gradient electroconductive heating films on transparencies.
