Abstract
1278057 Indicating-apparatus OAK ELECTRO/NETICS CORP 25 July 1969 [25 July 1968 19 May 1969] 37441/69 Heading G1J [Also in Division G2] An arcuate shaped prism 10 has an object surface 14, a reflecting surface 12, and an image surface 16. Indicia 18 adjacent the object surface and pointers 30 rotatable in a path adjacent the object surface can be viewed through the image surface. A second prism 20 is arranged to display indicia 28 and pointers 32, in a similar manner to prism 10. A third prism 44 shows further indicia 52. The image surface may be convex.
