Abstract

542,164. Detecting leaks in pipe joints ABBEY, C. E. I April 24, 1940, No. 7360 [Class 99 (ii)] [Also ir Group VI] An annular casing A<SP>1</SP> A<SP>2</SP>, B, forming a sound-box comprises two portions hinged at D so that they may be separated to en close a pipe joint, and has an opening E at which a stethescope or the like is attached. The hinged parts are held in position by springs F<SP>1</SP>, F<SP>2</SP>. Rubber packing may be used to ensure the fit of the appliance.
