Device for examining luggage by means of X-rays
First Claim
1. In a device for the inspection of objects, particularly luggage by means of X-rays emanating from an X-ray flash generator and passing through the object to be examined, to produce a shadow image on a fluorescent screen, which is received by a TV camera feeding an intermediate store, from which the stored video signals from the TV camera may be supplied to a TV monitor, and in which the X-ray flash generator, TV camera and intermediate store are interconnected by a control unit, the combination of the TV camera containing a pulse generator synchronized with the power supply line alternating current voltage, and the control unit being a synchronizing-unit rigidly coupling the line voltage to the TV camera and the X-ray flash generator, which synchronizing-unit, upon triggering of a start pulse initially prepares the intermediate store and thereafter triggers the X-ray flash synchronously with the supply line alternating current voltage.

Abstract
A luggage inspection apparatus utilizing fluoroscopic examination in conjunction with an X-ray generator, with the fluoroscopic picture being received by a TV camera, the video signals of which are supplied to an intermediate store for ultimate supply to a TV monitor, the camera containing an AC line-coupled pulse generator for synchronizing the camera and the X-ray flash generator, which pulse generator is electrically interconnected with a synchronizing unit which, upon the initiating of a starting pulse, thus likewise synchronously triggers the X-ray flash generator with respect to the AC supply line.
