Abstract
Abstract An X-ray inspection system includes placement of an article to be inspected in a stationary position between an X-ray source and a fluorescent screen, focusing the X-ray shadow picture produced on the fluorescent screen on the target of a television camera tube capable of integrating, preferably through a light intensifier, for a sufficient time to produce an intense electrostatic image, transferring the image to a storage device by snatching a single frame, and displaying the image in the storage device continuously on the picture tube of a monitor while moving the article for inspection of a different area and while producing a new electrostatic image on the target of the camera tube.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A process for X-ray inspection of articles, which process comprises interposing a stationary article between an X-ray source and a fluorescent screen, forming an optical image of the fluorescent shadow picture on the screen of an integrating camera tube to induce an electrostatic image on its target, integrating the image on the target for a period at least several times as long as a video scan period, snatch-scanning the target of the camera tube and transferring the integrated image to a storage device, displaying the image which is in the storage device as a visual image on the picture surface of a television monitor, and moving the article during display of the image of the article in its previous position.
Claim 2
Dependent Claim
120 words
A process for X-ray inspection of articles, which process comprises interposing a stationary article between an X-ray source and a fluorescent screen, forming an optical image of the fluorescent shadow picture on the screen of an integrating camera tube to induce an electrostatic image on its target, integrating the image on the target for a period at least several times as long as a video scan period, snatch-scanning the target of the camera tube and transferring the integrated image to a storage device, displaying the image which is in the storage device as a visual image on the picture surface of a television monitor, and moving the article during display of the image of the article in its previous position.
Claim 3
Dependent Claim
48 words
A process as in claim 1, in which the target of the camera tube is erased after placement of the article to prepare the camera tube for reception of an image of the article, and the article is moved after transfer of its image to the storage device.
Claim 4
Dependent Claim
28 words
A process as in claim 2, in which the visual image is displayed on the monitor continuously until transfer of the next succeeding image to the storage device.
Claim 5
Dependent Claim
40 words
A process as in claim 3, in which the transfer of the image from the camera tube to the storage device is at a predetermined time after commencement of build-up of the image on the target of the camera tube.
Claim 6
Dependent Claim
24 words
A process as in claim 4, in which the area of target scanned is varied to produce varying magnification of the ultimate visual image.
Claim 7
Independent Claim
130 words
A system for X-ray inspection of articles, comprising an X-ray source spaced from a fluorescent screen, means for positioning an article in a temporarily stationary position between the X-ray source and the fluorescent screen, an integrating camera tube, an optical system for producing an optical image of the shadow picture of the fluorescent screen on the screen of the camera tube, an image storage device, means for snatch-scanning the electrostatic image on the target of the camera tube and transferring it to the storage device, timing means for initiating the transfer of the image after integration on the target for a period at least several times as long as a video scan period, and means for continuously displaying a visible reproduction of the image which is in the storage device.
Claim 8
Independent Claim
130 words
A system for X-ray inspection of articles, comprising an X-ray source spaced from a fluorescent screen, means for positioning an article in a temporarily stationary position between the X-ray source and the fluorescent screen, an integrating camera tube, an optical system for producing an optical image of the shadow picture of the fluorescent screen on the screen of the camera tube, an image storage device, means for snatch-scanning the electrostatic image on the target of the camera tube and transferring it to the storage device, timing means for initiating the transfer of the image after integration on the target for a period at least several times as long as a video scan period, and means for continuously displaying a visible reproduction of the image which is in the storage device.
Claim 9
Dependent Claim
25 words
A system as in claim 6, including means for erasing the target of the camera tube to prepare it for reception of a new image.
Claim 10
Dependent Claim
27 words
A system as in claim 7, including timing means for activating the positioning means to move the article after transfer of the image to the storage device.
Claim 11
Dependent Claim
16 words
A system as in claim 8, in which the storage device is an electrical storage tube.
Claim 12
Dependent Claim
15 words
A system as in claim 9, inclUding means for varying the area of target scanned.
