Abstract

490,255. Compound sheet materials. AKTIEBOLAGET LINHAM. April 26, 1937, No. 11896. Convention date, April 28, 1936. [Class 140] [Also in Group XX] In screens for intercepting secondary radiation in X-ray photography, comprising an inner portion of grid form consisting of thin lead plates with intermediate spacers of ray permeable material, the inner portion is protected on both sides with layers of flexible material, e.g. linen fabric secured at several points by means of an adhesive. As adhesives, natural and synthetic resins, casein latex, glue, or cellulose may be used. Specification 479,389, [Group XX], is referred to.
