Title: Precision balance
IPC: G01G23/32
Filed: 1963-06-05
Abstract: 964,769. Weighing apparatus. MEPAG A.G. June 5, 1963 [Feb. 18, 1963], No. 22379/63. Heading G1W. A precision balance which gives direct indication for both additive and subtractive weighing operations comprises a weigh beam 4 pivoted on a knife edge 3 and carrying a weight measuring plate 5 inscribed with two arcuate rows of indicia 24, 27 respectively the sequence of one row being complementary to that of the other row (i.e. row 24 may have a sequence 0, 10, 20 to 100 with "0" at the top while the row 27 associated with subtractive weighing has 100 at the top) and an optical projection system, and a device to selectively screen off one or other of the rows of indicia. The short arm of the beam is equipped to carry a weight fan (not shown) from a yoke 10 (shown broken) and extending upward from yoke 10 is a column 11 to carry a control weight 13 on a hook 12. The condition for subtractive weighing is illustrated in which a slidable shutter 29 is positioned to permit an image 27<1> of the indicia row 27 to appear on a ground glass screen 18. A web 32 of the shutter intercepts part of a light beam 19 so that no image of the other row of indicia appears on the screen. For additive weighing a shaft 37 is turned anti-clockwise so that a rod 35 is moved to the other end of a slot 34 in a flange 33 of the shutter, thus causing the shutter to move to the right and allowing only the image of indicia row 24 associated with additive weighing to appear on the screen. At the same time a lifting member 37 on the shaft lifts the control weight 13 off the hook 12 of the pan carrier assembly. TARE ADJUSTMENT, For example when it is desired to add material to a partially filled vessel on the scale pan an approximate taring device (not shown) is adjusted, and then a precision taring device is actuated by turning a shaft 23 carrying an eccentric disc 22. This raises or lowers a U shaped arm 20 on a shaft 21 and a magnifying system 16 and illuminating system 15 carried by it. The shaft 23 is rotated in the appropriate direction until the image of the zero graduation associated with row 24 is exactly centred in a catch mark 26 on the screen. The zero of the row 27 is located when subtractive weighing.
