Abstract

549,110. Coating with metals. LUMB, C. F. April 21, 1941, No. 5131. [Class 82 (ii)] [Also in Group XL] Interference with wireless apparatus is prevented by a screening device formed by spraying zinc powder of the order of 150 mesh at a high temperature and speed on a base which may be synthetic resin or wood. An additional adhesive may be used. Reference has been directed by the Comptroller to Specification 21066/,11, [Class 82 (ii)], and to "Metal Industry," 15th May, 1936, page 558. Column 2.
