Abstract
444,852. Liquid-levels. BRADSHAW, A., 47, Adelphi Street, Sheffield. April 12, 1935, No. 11305. [Class 97 (ii)] A bubble tube carrying member B in which the tubes are rotatable has a plane boundary with a prismatic member for ready sliding attachment of member B to a larger stock A. The bubble tubes C<2>, C<3> are carried in a tube C rotatable in a cavity in member B and held in position by an annular ring D screwed to member B. A ring G<1> is attached to tube C and carries a zero graduation against which the inclination of the stock A may be read on a scale on ring D. The tube C may be clamped in position by screws F.
