Abstract

526,213. Effecting operations at predetermined atmospheric pressures. GRASEBY, R. C. March 10, 1939, No. 7827. [Class 8 (ii)] A pin 1 is moved at a predetermined atmospheric pressure by springs 24 through a lever 7 which is normally locked by a bell-crank 8 coacting with a lever 12 held against motion by a grooved barrel 14. This barrel is rotated by an aneroid bellows 22 through a spring pressed lever 18, so that the lever 12 and trigger 7 are released at the desired atmospheric pressure.
