Abstract

793,282. Prisms. OWENS-ILLINOIS GLASS CO. March 17, 1956. No. 8412/56. Class 97(1) [Also in Group XL(b)] A reflecting prism 75 used in one embodiment of photo-electric glassware inspection apparatus (see Group XL(b)) is constructed so as to split incident beam a into two separate beams 76, 77 emerging therefrom acutely to one another. The incident beam is bisected at the meeting line 80 of reflecting surfaces 81, 82, and one portion is deflected from surface 83.
