Abstract

619,006. Spectacles. REIJNDERS, F. H. Nov. 19, 1946, No. 34217. Convention date, Oct. 20, 1938. [Class 97 (i)] Spectacles for observing stereoscopic images projected on a vertical screen comprise a frame 1 from which selective optical means such as polarizing analysers 5 are suspended by pins 4 so as to be rotatable about axes parallel to the line of vision, so that when the head is tilted sideways the analysers 5 remain vertical. The supporting clamps 3 may slide along the frame. Specifications 16123/95, [Class 97], and 478,557 are referred to.
