DETECTION UNIT OF MULTICHANNEL FLAW DETECTOR Russian patent published in 1998 - IPC

Abstract RU 2122201 C1

FIELD: estimation of quality of parts in process of their manufacture and repair. SUBSTANCE: part quality estimation is performed with use of radioactive sources of ionizing radiation and collimated units of detectors. Collimation device is positioned on way of radiation flux coming from flaw detector. When eccentric rollers arranged symmetrically relative to radiation flux axis turn collimator window size changes from minimum slit to maximum rectangular one. EFFECT: high-speed and safe operation. 4 dwg
