Abstract: ABSTRACT:             Thermal-radiation imaging devices, elements and systems are described.  The device comprises on a substrate (2) e.g. of sapphire semiconductor bodies or body portions in the form of parallel elongate strips (1), e.g. of cadmium mercury telluride.  Biasing-electrode (6 and 7) e.g. of gold are spaced on the strips (1) for causing a bias current predominantly of majority charge carriers to flow along each strip (1).  The bias current supports an ambipolar drift of radiation-generated free minority carriers in the opposite direction.  At a read-out area (8) in the drift path each strip (1) branches into two parts separated by a slot (13) parallel to the strip (1).  One part (11 in Figure 2) provides the contin-uation of the drift path, and narrowing of the continua-tion of the ambipolar drift path in this part (11) improves the device characteristics by increasing the electric field in this area.  A read-out connection com-prises the other part (12 in Figure 2) and is separated by the slot (13) from the adjacent biasing-electrode means (6 or 7).  Metal layers (6, 7, 8) providing the biasing-electrode and read-out connections may extend onto the substrate (2) over a more rounded edge at the ends of each strip (1).

Abstract: ABSTRACT OF THE DISCLOSURE A hollow body is made up from individual tube elements having gro-ove and tongue connections constructed in their ends.  The tube ends also carry flanges disposed on the outside and/or inside thereof, the flanges each hav-ing an oblique rear surface so that the flange width increases towards the base of the flange.  The two flanges of confronting tube ends are overlapped by a ring which has an inner ring channel, the side edges of which enclose both flanges in the manner of a clamp.  The distance between these side edges when they are in the unstressed state is shorter than the distance between the base points of the two oblique surfaces.  The ring abuts the outer sides of the tubes and can be tightened by a clamping device.  The tube elements may each be formed by a plurality of sectional shells.

Abstract: ABSTRACT OF THE DISCLOSURE         A hot steel strip is displaced under longitudinal tension along a transport path from an upstream feed bridle to a down-stream feed bridle.  The hot steel strip is stretch-bent adjacent the upstream feed bridle to free scale from the strip in an enclosure in which the freed scale is collected.  Downstream of this enclosure high-pressure water jets in another enclosure are played on the strip to free and separate the remaining scale from the strip.  This freed scale is also collected.  The strip is then pinched between a pair of rollers downstream of the high-pressure water jets so as to drive all water from the surfaces of the strip, whereupon it passes through the downstream feed bridle.
