Abstract

1296570 Cine projectors O HABERKERN 18 Sept 1970 [22 Sept 1969 6 Oct 1969] 44562/70 Heading G2A and G2E A cassette-loading cine projector 21 has a projection lamp 15 separated from the projection gate 3 by a partition 16, the light being transmitted to gate by a glass light guide rod 7 extending through an aperture in the partition. Film is wound from spool 2 to spool 6 and passes over a sprocket wheel carrying a rotating reflective prism 8 which provides optical compensation. Light from prism 8 is directed via mirror 9 through objective 11, there being a tilting mirror 12 which directs the projection beam either through partition 16 on to integral screen 14, or out of the housing on to a distant screen.
