Abstract

946,335. Indicating and registering. W. & T.AVERY Ltd. May 2,1962 [May 4,1961], No. 16130/61. Heading G1W. In a weighing apparatus an optical projection system is used to provide respectively two separate images on two screens of a single weight indication. As shown Fig. 1 a transparent indicator graticule A which may be of cylindrical or disc shape is rotatable between a lens 'B' and a light source (not shown) through an angle proportional to the weight. A mirror C is positioned adjacent the focal point of the lens to reflect half of the light beam on to a translucent screen E. A second mirror F reflects the other half of the beam to a screen H. In a modification Fig. 2 (not shown) there is a further pair of mirrors, which respectively receive the light beams reflected from the mirrors C and F and respectively turn each beam through a further angle before the beams are received on the respective screens.
