Abstract
946,409. Extensometers. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 16,1962 [April 20,1961], No. 14399/61. Heading G1M. For measuring the extension of an axiallybored stud 3, so that by heating it (using a heating coil 14 in the bore), to give a predetermined extension before tightening up nut 4, a predetermined strain may be obtained, a socket spanner 5 carries a micrometer screw-cap 7 having a tube 11 extending through the bore stud for the flow of gas measured by a rotameter 18, an orifice in the end of tube 11 being variably obstructed by axial movement of a tapered screw 13 secured to the end of the bolt. Specification 946,408 is referred to.
