Abstract
1471199 Optical projectors J FRANK and H N LEVINSON 15 July 1974 [16 July 1973] 31261/74 Heading G2J An optical projector for use in detecting dyslexia in young children projects an image which moves across the screen at a rate which appears blurred to a dyslexic child but not to a normal child. As shown in Fig. 5, an overhead projector has independent drives for film strips 16, 18, strip 18 bearing words 17 and strip 16 bearing background images 19. One strip is moved and the other kept still while in both cases the child looks at the words 17 and signals if they appear to him to be blurred. As shown in Fig. 1, strip 16 moves between rollers 30, 32 having axles 34, 54 on which are mounted friction discs 38, 52. A pulley 56 driven by an electric motor (not shown) rotates a shaft 42 carrying driving discs 40, 50. A knob 44 moves shaft 42 longitudinally to engage discs 38 and 40 or 50 and 52 to provide forward or reverse transport of strip 16, the position of engagement determining the speed of the strip. Strip 18 has a similar, independent drive system operated by a knob 84. The projection head 24 is carried by an L-shaped rod 60 pivoted at 62 to the projector housing 26. The drive systems for the strips 16 and 18 are mounted on a body (102), Fig. 2 (not shown) which is rotatable relative to the housing 26.
