Abstract: A process for producing hot-rolled aluminum strip for can making in a rolling plant whose yearly production capacity is below 250,000 tons. Feed material is fed through a reversing roughing stage to form a strip which immediately thereafter is finish rolled. The finish rolling is followed by heat treatment of the strip coiled up into coils. In this case, during the last finishing rolling passes, recrystallization in the rolled material is suppressed by means of controlled temperature management of the hot strip and the recrystallization is specifically brought about only outside the rolling train, directly following the finishing rolling.

Abstract: The invention relates to a process for producing hot-rolled aluminum strip for can making, especially in rolling plant whose yearly production capacity is below 250,000 tons, having a reversing roughing stage for the feed material, which is used hot, and immediately thereafter finishing rolling of the strip, which is followed by heat treatment of the strip coiled up into coils. In this case, during the last finishing rolling passes, recrystallization in the rolled material is suppressed by means of controlled temperature management of the hot strip and the recrystallization is specifically brought about only outside the rolling train, directly following the finishing rolling.

Abstract: An electroradiographic display with a high picture quality at low radiation intensities is obtained with a device consisting of a source of X-rays, an electrode passing X-rays, an intermediate recording space for an object to be displayed, an electrode on the side remote from the recording space on which a layer of dielectric material is disposed, and a second electrode with a photoconductive layer. The layers are separated by a gas gap which is bounded by one or more side walls. A direct voltage source is in electrical contact with the electrodes. The photoconductive layer comprises a granular photoconductive material in a binder. The gas gap between the dielectric layer and the photoconductive layer is from 50 to 500 .mu.m wide and the electrode passing X-rays has a surface resistance between 10.sup.3 to 10.sup.8 Ohms.

Abstract: The sensitivity of photoconductive layers of tetragonal lead monoxide in a binder is increased when the tetragonal lead monoxide produced by prior art process after being subjected to a further treatment has a grain size of 1 to 50 .mu.m and is dispersed in the binder without mechanical force and is sedimented on a layer carrier without mechanical force.

Abstract: An x-ray exposure device comprising a flat and plane rectangular chamber containing an ionizable gas and having walls provided with electrode structures which generate a potential distribution corresponding to that of two concentric spherical electrodes, an insulating foil on which charge carriers resulting from ionization of the gas by the x-radiation and displaceable in the longitudinal direction of the chamber being arranged therewithin.
