Abstract
1428830 Weighing apparatus OERTLING Ltd 17 May 1974 [25 May 1973] 25147/73 Heading G1W A optical projection system in a balance comprises, secured to the weigh beam 15, a transparent scale-carrying plate 21, an image 34 of part of which is produced on a screen 26 to indicate the weight, a fixed member 32, and a reflector 31 arranged to move as the weight increases and to deflect part of the optical beam of the system on to the fixed member 32 whereby an image 35 is produced on the screen 26 which co-operates with a scale 36 to provide an approximate weight indication. The optical beam of the system is produced by lamp 23 and lenses 24, 25, and is directed on to screen 26 by fixed mirrors 27, 28, 29. The reflector 31 is mounted on an arm 30 fixed to the weighbeam 15, and directs light on to the member 32. Member 32 has a slit 33, an image of which is produced on the screen as image 35.
