Abstract: 1,171,105. Weighing apparatus. PORTERLANCASTRIAN Ltd. June 2, 1967 [June 2, 1966], No.24553/66. Heading G1W. Apparatus for weighing containers e.g. casks and barrels comprises a support arrangement which is supplied with fluid under pressure until the arrangement supports the container whose weight is to be assessed, the fluid-pressure indicative of such weight then being determined while excess fluid pressure is vented to atmosphere. As shown, the support arrangement comprising an open-sided box-shaped member 22 is provided with a lifting screw 24 which supports the container to be weighed and is mounted on a flexible diaphragm 18 which forms part of a fluid chamber 32. A bolt 28 fixed to the centre of the diaphragm 18 is arranged to bear on a stem 28a which is movable to actuate a release valve 26, the valve 26 being mounted on a member 38 which is fixed by bolts to a diaphragm retaining ring 34. With the screw 24 in contact with the container to be weighed fluid under pressure is supplied by way of a restrictor 30a to the fluid chamber 32 and to the valve 26 and a pressure gauge (30b, Fig. 4, not shown) and the pressure of such fluid is increased until the screw 24 bears the entire weight of the container. Further increase of pressure causes the bolt 28 to move the stem 28a and thereby actuate the release valve 26. Thus the pressure indicated on the gauge is indicative of the weight of the container.

Abstract: 714,861. Measuring physical qualities and capacitance. FOXBORO CO. Oct. 22, 1951. No. 24612/51. Class 37. Relates to apparatus for measuring physical qualities, e.g. moisture content of grain or thickness of rubber, by passing the material under test between or near two plates forming a condenser and measuring the variation in capacity. According to the invention, the condenser CM Fig. i varied by the material is connected to an adjustable circuit I2, I3 forming part of the measuring circuit through an adjustable condenser CS. This has the result of reducing the effective range of variation; as shown in Figs. 3 and 4, the curves variation of capacity with moisture content at three temperatures of Fig. 3 becomes the curves of Fig. 4. The condensers CS, CM and I3 of Fig. i may form one arm of a capacitative bridge. The condenser CS may be replaced by an adjustable differential capacity CSV Fig. 5 providing series and parallel condensers, or by two adjustable series condensers in parallel, Fig. 6 (not shown). Temperature compensation to reduce the three curves of Fig. 4 to one may be obtained by varying capacity 13 Fig. 2 automatically from I5 in accordance with temperature.
