Title: Improvements in or relating to bag filling and weighing machines
IPC: G01G13/00
Filed: 1947-04-16
Abstract: 636,482. Photo-electric bag-filling machines. TALBOT, G. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. April 16, 1947, No. 10074. [Class 40 (iii)] In a bag-filling machine, interruption of the light to a photo-cell by the pointer of a weighing machine on the pan of which the bag, is resting, cuts off the supply of filling material to the bag. The filling of each bag is initiated by a press-button to start a motor 1 driving a cam 2 which first closes a switch 9 to maintain the motor supply and then rocks a crank 17 to open a sliding valve 22 in the supply duct, this valve latching open by a lug 27. After a predetermined rotation, the cam opens switch 9 to stop the motor. When the pointer of the weighing machine interrupts the light to the photo-cell, a solenoid D releases the slide valve and the motor is restarted by a relay C so that cam 2 again rotates, reclosing switch 9 and operating a lever 18 to tip the bag out of the pan 36. The light path to the photo-cell is now again complete and the cam rotates until switch 9 is again opened in the original starting position. If a bag bursts, coupled switches 5a, 5b may be pressed to cut off the supply to the bag and run the motor to discharge it from the pan. By pressing button 8, the weight of a bag may be checked since the discharge of the bag is prevented.

Class 97(1) In a prism system in which the prisms are rotatable before an objective to vary the magnification a pair of colour dispersion wedges are rotatable in opposite directions in planes perpendicular to the optic axis of the objective to correct for the residual dispersion of the prisms. As shown in Fig. 1 an anamorphotic zoom prisms system 13 as described in Specification 823,129 is placed before an objective 14, the prisms in the system being rotated by a crank 15 to vary the magnification produced by the prisms. Before the system 13 are dispersive wedges 21, 22 each formed of two oppositely directed wedges cemented together, the wedges being simultaneously rotated about the optical axis 10 of a variable collimating lens 11 by a pinion 18 driven by suitable gearing from the crank 15 to reduce the resultant chromatic errors in the image. The anamorphose may comprise two prisms above rotatable before the objective and the wedges 21, 22 may be placed between the anamorphoser of the objective 14. The rear element 92 of the collimator may be cemented to the front wedge 21. Numerical data for one example are given and the theoretical basis of the invention is explained.
