Abstract

328,112. Harkness, A. S. April 15, 1929. No Patent granted (Sealing fee not paid). Projection screens comprise a lace-curtain fabric wherein the ground is covered completely and uniformly with patterning stitches without patterning effect, so as to present at one side as nearly as possible a solid picture projection surface, and at the other side a cellular surface adapted to collect sound waves from a soundreproducing apparatus. The screens may be made in one seamless width of cotton, silk, wool, flax, or linen, may be treated with fireproof solutions, and may be treated with paint or metallic powders.
