Abstract

905,080. Testing pressure in closed vessels. GENERAL ELECTRIC CO. Ltd. Dec. 21, 1960 [Jan. 6, 1960], No. 481/60. Class 106 (2). The pressure of a gas inside a closed frangible receptacle is determined by breaking the receptacle inside a hermetically-closed container using means operable from outside the container and observing the new pressure within the container by means of a pressureindicating device connected to the container. As shown, an electric lamp 16, of which the filling pressure is to be determined, is held firmly in holder 15 secured to a plate 1 by means of an apertured plate 17 and spring 21 inside an enclosing vessel 23 open at the bottom and pressed against a gasket 22 on plate 1 by a screw-clamp 24. The threaded rod 25 of the latter threadedly engages a bar 26 provided with keyhole slots 28 for engaging vertical bolts 27 mounted on the plate 1. The latter is carried by a framework 3 standing on a base 2 and has a small orifice leading via tube 4 and a three-way joint 5 to a mercury manometer 7. The system is sealed from the atmosphere by means of valve 11 and the pumping stem 32 of the lamp broken by a breaking member 33 carried by a spindle 34 extending hermetically and rotatably through the vessel wall 23 and provided with an arm 35 for manual rotation. Alternatively, the breaking member may be spring-loaded and held in constraint by a releasable catch; or it may be electrically operated. The scale 36 records either the difference of pressure before and after breaking, or it may be calibrated directly, for an apparatus of given dimensions, to indicate the initial pressure in the bulb.
