Abstract
423,913. Specific-gravity estimating- apparatus. CHLORIDE ELECTRICAL STORAGE CO., Ltd., and BROWNE, A. W., Exide Works, Clifton Junction, near Manchester. March 22, 1934, No. 25099. Divided out of 426,046. [Class 97 (iii)] A pointer a is sprung over the head b<1> of a pivot pin b on a celluloid or like sheet c and rests between the head b<1> and a collar b<2> which spaces it from the sheet c. The pointer, preferably made of ebonite, has its centre of mass and centre of volume non-coincident with each other and the pivot pin so that it turns about its pivot to indicate the specific gravity of the liquid in which it is immersed. The sheet c is spaced from the wall of an electric accumulator cell and may be graduated to indicate the state of charge. The collar b<2> may have a rounded face towards the pointer. Specification 410,935 is referred to.
