Abstract
Abstract This invention relates to apparatus for the simultaneous, continuous X-ray examination of both sidewalls of a drivably mounted expanded motor vehicle tire, of the kind comprising two X-ray tubes and two fluorescent screens with mirrors arranged subsequent to them to reflect the pictures on said fluorescent screens to a sensing-camera arrangement with reproduction on monitors. In the invention, the fluorescent screens arranged for location at least partly within the air-space of the tire, together with said mirrors. Each X-ray tube is situated opposite the side-wall of the tire facing it, and which is to be irradiated. The fluorescent screens are generally flat and are situated parallel or approximately parallel to each other and to the two side-walls of the tire within its air space.

Apparatus for the simultaneous, continuous X-ray examination of both side-walls of a drivably mounted expanded motor vehicle tire, by means of two X-ray tubes and two fluorescent screens with mirrors arranged subsequent to them to reflecT the pictures on said fluorescent screens to a sensing-camera arrangement with reproduction on monitors, the invention which consists in that said fluorescent screens arranged for location at least partly within the air-space of the tire, together with said mirrors, and in that each said X-ray tube is situated opposite the side-wall of the tire facing it, and which is to be irradiated.
Claim 3
Dependent Claim
31 words
Apparatus according to claim 1, wherein said fluorescent screens are situated at least substantially approximately parallel to each other and to the two side-walls of the tire within its air space.
Claim 4
Dependent Claim
37 words
Apparatus according to claim 2, wherein a flat mirror is disposed at an inclination to each said fluorescent screen and with its reflecting surface facing the open area of the tire between the two peripheral edges thereof.
Claim 5
Dependent Claim
19 words
Apparatus according to claim 3, wherein the angle of inclination between said mirrors and said fluorescent screens is 45*.
Claim 6
Dependent Claim
61 words
Apparatus according to claim 4, wherein a common flat mirror is located within the inner periphery of the tire and opposite said mirrors and the reflecting surface of said common flat mirror extends at least substantially parallel to the reflecting surface of one of said first mentioned mirrors and reflects the two pictures on said fluorescent screens to a sensing camera.
Claim 7
Dependent Claim
63 words
Apparatus according to claim 4, wherein two further mirrors are provided within the inner periphery of the tire each at a symmetrical angle to the reflecting surface of one of said first-mentioned mirrors, said two further mirror reflecting the picture on their respective fluorescent screens separately to two sensing cameras each said camera having a monitor or an image-mixer and a single monitor.
Claim 8
Dependent Claim
27 words
Apparatus according to claim 4, wherein a sensing camera for receiving the pictures on both said fluorescent screens and having a monitor, is situated opposite said mirrors.
Claim 9
Dependent Claim
51 words
Apparatus according to claim 4, wherein there is provided an optical system for receiving the pictures on both said fluorescent screens, said optical system being situated opposite said mirrors and being coupled to one end of an optical-fibre light conductor, the other end of which is connected to a sensing camera.
