Abstract: 1436186 Detecting flaws in metal M SHEPHERDSON 21 March 1974 [5 Feb 1973] 5528/73 Heading G1N Apparatus for testing an elongate element comprises stationary coils connected to a polyphase supply for inducing a magnetic field transverse to, and rotating about, a longitudinal axis of the element, and means responsive to magnetic anomalies arising from defects in the material. A system of exciter coils 1 Fig. 1 on slotted laminated steel cores 2 is connected to a 3-phase supply to generate in test material M a transverse magnetic field rotating about a longitudinal axis. A toroidal detector coil 3 radially within the exciter coil system 1 responds to a material defect by representing an e.m.f. to an indicating system, Fig. 2, comprising an amplifier 10 a phase-sensitive detector 12 fed with reference signals from the supply, filters 11, 13 and a display unit 14. For eddy-current testing of magnetic materials the incremental permeability may be reduced by a longitudinal saturating field provided by coils 4, 4 enclosed within a cylindrical steel yoke 5 with disc pole-pieces 6, or by a soft iron yoke with permanent magnets. Where surface eddy-currents are to be induced the apparatus may be adapted to high frequencies by removing the laminated cores 2 or replacing them with more suitable material, e.g. ferrite. Alternative detection arrangements include: the division of a toroidal coil into sectors each connected to a separate display system; and a set of polyphase detector coils in which the phasor sum of the induced e.m.f.s, normally zero, is unbalanced by the presence of a defect. In one embodiment two toroidal detector coils are positioned close together and connected differentially.

Unoccupied tool positions in the magazine are indicated by a zero indication in the core store. During operation of the machine tool, a request from the control system, (not shown), on a line 20 is applied through a control device 6 to a coincidence stage 8. The core store 3 is simultaneously read out by timing pulses on a line 7 from the control device and the tool indications, through the buffer 4, are held in a device 5 and compared with the request in stage 8. The timing pulses are also fed to a pulse counter 10 through a line 9. At coincidence between request and readout the cycling of store 3 is stopped and the counter 10 is held by a pulse on a line 11. The contents of counter 10 is then compared with the total tool positions of the magazine 1 in a computing device 14 and the direction of movement of the magazine for shortest travel of the requested tool to a tool changing device 19 commanded. A tool position change is sensed by a transmitter 17 which actuates a counter 16 and when the contents are ascertained by the computing device to correspond to the requested tool being at the exchange position a switch-off command for the magazine 1 is issued. The tool is then extracted and introduced into the spindle, (not shown) of the machine-tool. The tool indication is then cancelled in the core store and transferred to a buffer store 5a; the indication being shown on a device 13. When a tool is exchanged the indication of the used tool is transferred from the buffer store 5a to the core store. The magnetic core store 3 can be replaced by shift registers.
