Abstract
512,983. Indicating liquid - levels. EVANS, W. E. (Corcordia Elektrizitats-Akt.-Ges.). March 11, 1938, No. 7693. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 5, 1938.]. [Class 123 (i)] [Also in Group XXI] A combined liquid-level indicator and pressure gauge for use in a hand fire extinguisher consists of a tube h up which liquid is forced by the pressure in the extinguisher, and a float c with an upwardly extending sleeve f surrounding the tube. The liquid in the tube and the top of the sleeve are visible through a bell g.
