... 306,351. Robertson, J. H. June 25, 1928. Compound transparent sheets.-To secure firm adhesion between the glass and celluloid sheets forming non-splintering transparencies, the glass is first coated with a cement consisting of a gelatinous silicate in a hot solution of gelatine with or without potassium chrome alum. or of albumen, or of casein. The coated face is dried and a celluloid sheet of about 0.005 inch thickness, softened with an acid such as propionic acid is secured thereto, or alternatively, a solution of 1 gram celluloid, 30 ccs. amylacetate, and 4 cos. propionic acid may be applied thereto.

MINERAL WOOL PRODUCT, METHOD FOR ITS PRODUCTION, IMPREGNATING MASS THEREFOR, AND USE THEREOF

The surfaces of coated mineral fiber products, as a rule, also form a barrier against dust and trickling particles, are however not accepted for technological reasons and reasons of cost unless their intended use requires coating or impregnating for different reasons. In order to provide such mineral wool products, which - in view of their use usually are not coated, with a barrier against dust or trickling particles, it is proposed to provide their surfaces with an impregnating mass applied in a foamed form. The froth is destroyed during drying or curing to open macroscopic pores between the fibers, whereby an open surface structure of the product is preserved. Nevertheless the impregnated layer offers effective protection against solid matter passing through it. Impregnation by means of a foam incurs surprisingly low additional costs, even in large series production. It is of particular importance that by selecting a suitable impregnating mass, the tactile sensation of the product may ...
