An X-ray inspection system for manually or automatically performing digital fluoroscopy inspections and/or computed tomography inspections by X-ray examination of manufactured parts incorporates a computer system which automatically analyzes the inspected parts for flaws. The system includes apparatus for automatically positioning the parts in an X-ray machine for obtaining fluoroscopy and tomography views of the part and for acquiring data from the inspections at production rates. The system automatically identifies the location of rejectable flaws in the parts during the fluoroscopy scanning and subsequently identifies those locations for obtaining tomography scans, if the identified flaw location is questionable. The system can automatically reject parts containing flaws identified during the fluoroscopy inspections. This system operates in a real-time environment by providing analysis of one part while a subsequent part is being subjected to X-ray examination. The data obtained during each examination is archived and stored for tracking the part in further manufacturing processes.

X-ray inspection system

A method for transmitting information with a desired bandwidth while suppressing interference due to harmonics of a system-wide signal, by transmitting each bit of information as a pair of spaced rectangular envelope modulation pulses having a time interval therebetween essentially equal to the reciprocal of the difference between the frequencies of a carrier and of adjacent harmonics of the undesired system-wide signal. A sequential plurality of double-pulse modulating waveforms can be transmitted for reception by a receiving means having a like plurality of demodulators each synchronized and sequentially enabled only when one of the pair of modulating pulses are present. A novel double-pulse demodulator means, capable of essentially rejecting undesirable harmonics in a system utilizing a data carrier modulated to be interlaced between sequential harmonics of a system-wide signal, and novel means for synchronous gating thereof, are disclosed.
