Abstract

1,080,875. Transparency viewing apparatus. F.J.J.M. HAVENITH. Aug. 13, 1964 [Sept. 20, 1963], No. 37131/63. Heading G2A. [Also in Divisions F4 and G5] Transparencies are carried in envelopes 16 in an opaque or slightly translucent lampshade 10 rotatable about lamp 3 by means of electric motor 5 supported by structure 4 which is secured to the lamp-holder 2. Heat filter 6 protects the motor from over-heating. Shaft 7 drives stirrup 9 which supports the shade at 1 r.p.m. for example. Monochrome or multi-colour light filter 14 surrounds the lamp.
