Title: Apparatus for determining rates of change in weight
IPC: G01G19/00
Filed: 1954-05-21
Abstract: 779,259. Automatic rate of flow control systems. CIBA Ltd. May 21, 1954 [May 22, 1953 ; Feb. 12, 1954], No. 15090/54. Class 38 (4). [Also in Group XL (b)] Apparatus for deter. mining rate of change of weight comprises a weighing device having a movable scale pro, vided with alternate light and dark areas, a movable member provided with corresponding alternate light and dark areas, a photoelectric cell receiving light through the scale and the movable mem. ber and means responsive to the cell output to bring the movable member into synchronism with the scale, thus indicating the speed of the scale. As shown, a scale 3 carried by a moving member of a weighing-machine carries a conventional scale 11 which is projected on a screen 6 for visual readings of weight and a further scale 12 consisting of alternate opaque and transparent areas. These areas are superimposed optically by light source 5, and a suitable optical system on to similar areas in a moving band 10. A chopping plate 8 is provided to assist in amplification of the cell output. The arrangement is such that the cell output is responsive to difference in speeds of the two sets of apertures and is used to control the speed of the second set so as to bring it into synchronism with the scale. The current supply to the means driving the second set is an indication of the rate of movement of the first scale and hence of the rate of change of weight. In the arrangement of Fig. 3 (not shown) the second set of apertures is formed in an endless band which is motor-driven by the amplified cell output, the operating current of the motor which is of the eddy current type indicating the speed of the band. In an alternative arrangement (Fig. 4) a deep screw-thread is used as the second set of apertures, the scale 12 having the individual portions shaped to correspond to the sloping sides of the thread (Fig. 5, not shown). A counter may be operated by the means driving the second set of apertures so as to shut off, e.g. a gas supply when a particular quantity has been supplied. Should the scale and member fall a great deal from synchronism maximum and minimum relays may be operated by the cell output to bring them into synchronism more quickly. An arrangement is described in which the flow of gas from a container being weighed is maintained constant (Fig. 6, not shown). This is done by causing a constantspeed motor to drive a threaded shaft on which is a nut driven at a rate determined by cell output. The nut operates a lover to open or close a valve if the speeds of nut and shaft differ.

Abstract: 972,206. Valves. K. EHLERS. April 19, 1963 [April 19, 1962], No. 15444/63. Heading F2V. A petrol filling nozzle is provided with a valve seat 3 for a plate or conical closure member 4. A member 8a, fixed to a hollow spindle 7, serves as an abutment for a spring 8 to urge the member 8a towards the closure 4. A second spring 9 acts between the member 8a and the closure 4. A stem 20 is located in the spindle 7, the stem and spindle being provided with notch 22 and aperture 21, respectively, which are aligned in the closed position of the valve and two rollers 24 movable in slots 25 of a yoke normally couple the stem and spindle. The yoke is connected to a diaphragm 26, loaded by a spring 30, the diaphragm forming an upper chamber 31 which is connected to a passage 27 opening at the spout 2 of the nozzle and two passages 28, 28a and 29 opening adjacent the valve seat 3. The underside of the diaphragm is connected through the space between the stem and spindle, passages 35b and passage 35c to the space adjacent the seat. The valve is opened by a lever 6 which acts on the stem 20 through a roller 17 and through thecoupling, with draws the spindle 7 to compress the spring 8. The fluid pressure at the inlet then opens the valve 4. The fluid flowing past the valve creates a suction at the passages 29, 35c and air is drawn through the passage 27 and the space below the diaphragm is maintained at a reduced pressure. When the end of the passage 27 is closed by the rising level of the liquid, the subsequent reduction of pressure in the chamber 31 raises the diaphragm 27 to move the rollers 24 out of the notch 22 of the stem, thus allowing the spindle 7 to move under the action of the spring 8 to close the valve. A spring 36 between the stem and spindle brakes the movement of the spindle 7. When the lever 6 is released the stem 20 moves to the right and the rollers 24 re-engage the notch ready for the next actuation. The arm 15 carried by the lever 6 passes through a seal 18. The lever 6 is forked and attached to two pivots which do not extend through the seal 18.
