Abstract

711,205. Hygrometers; determining specific gravity; thermometers. ANGLO-IRANIAN OIL CO., Ltd., and TOMASCHEK, R. K. A. Aug. 11, 1950 [May 11, 1949], No. 12543/49. Class 97(3) [Also in Groups XIX, XXXII, XXXVIII and XL(b)] An instrument for measuring or comparing linear forces of like direction comprises a coiled spring 36, Fig. 12 having a cross-section of substantial width to thickness ratio and having not less than 1.25 turns in the unextended state and capable of linear movement under the action of a linear force applied at one end, the spring being mounted so that the axis of the spring in the unextended state is inclined at an angle not greater than 40 degrees to the direction of the force; the angle being such that under the influence of the force the spring is extended into a state of extreme sensitivity. The spring is in such a state when the mounting angle is such that the graph of angle of twist against load is a simple inflection curve having the maximum sensitivity for twist and the load is that at which the latter occurs. As applied to a thermometer the base plate 32 adjusted by screws 33 carries a casing 34 which supports a mounting 35 for the spring allowing the axis of the latter to be rotated in two mutually perpendicular planes. The lower end of spring 36 bears a pointer 37 and is attached to a torsion wire 38, the opposite end of the latter being attached to a bimetallic strip 39 supported on a movable support 40 operated by a rack and pinion 41 for bringing the spring 36 into its extremely sensitive state. A hygrometer according to the invention comprises the adjustable spring mounting 14, Fig. 11, carried by the casing 13 supported on base plate 11, the lower end of spring 15 being attached to mirror 16 and a fine torsion wire 17, the opposite end of the latter being fastened to a hygrometer hair 18 supported by a rack and pinion adjustment 19. In the gas density measuring instrument the sealed casing 44, Fig. 13, provided with gas inlet 52 and outlet 53 supports the adjustable spring mounting 45. The sensitive spring 46 is attached at its lower end to mirror 84, the weak helical spring 47 and torsion wire 50, the latter carrying a light hollow pear-shaped vessel 51. The upper end of spring 47 is secured to a movable framework 48 operated by rack and pinion 49. The distortion produced in the spring under the action of an applied force may be measured by observing the elongation by means of a microscope, or the variations in capacity of a variable condenser, or the changes in ionisation currents produced by a radioactive material attached to the spring. Alternatively optical, electrical, or radioactive means may be utilized for measuring the angular displacement of the free end of the spring. Specification 711,206 is referred to.
