Abstract

1,126,916. Monitoring tool wear by radioactive tracers. FARBWERKE HOECHST A.G. Jan.28, 1966 [Feb.16, 1965], No.3910/66. Heading G1A. [Also in Division E1] A borehole drilling tool is formed with a cavity into which krypton<SP>8</SP> is sealed at a chosen depth. When the tool has worn down to the depth the krypton<SP>85</SP> is released and its radio-activity detected to operate an indicator, warning signal or stopping device. The krypton <SP>85</SP> may be mixed with a substance which reacts with the borehole fluid to produce a gas which ejects the krypton <SP>85</SP> from the cavity against the fluid-pressure in the borehole.
