Abstract

1278054 Prisms OAK ELECTRO/NETICS CORP 25 July 1969 [25 July 1968 19 May 1969] 37436/69 Heading G2J [Also in Division H1] A display device includes a prism 20 mounted for rotation about an axis 32, the arrangement being such that when the prism is in the full-line position shown indicia 36 may be seen at an observation face 24 as a result of reflection at a reflecting surface 22, but when the prism is in the dotted line position the indicia may not be seen. In modifications (not shown), multiple prism units may be used to selectively reflect one or more separate sets of indicia.
