Abstract

421,132. Lantern slides. MORGAN, H. M., 34, Red Lion Square, High Holborn, London. June 15, 1933, No. 17154. [Class 98 (ii)] An announcement slide for use with kinematograph &c. projectors is made of or comprises heatresisting glass. As shown, the slide A, Fig. 2, which is furnished with a backing C marked with lines D as in Specification 216,349, [Class 98 (ii)], is made of heat-resisting glass and is furnished with rounded corners B. The backing may also be printed or stamped with a fancy pattern E enabling parts of the backing to be removed, leaving transparent areas F which may register with coloured areas H in a cover slide G, Fig. 3. When a cover slide is employed either or both slides may be of heat-resisting glass and the two slides may be hinged together by means of an adhesive strip.
