The apparatus for burning the contaminated soot particles in the exhaust gases of diesel motors of vehicles comprising in the exhaust gas line a housing with a burner operated with a fuel/air mixture for burning the contaminated particles in the exhaust gas flow. The housing comprises a rotatably supported hollow cylinder through which the exhaust gases flow. The housing and the hollow cylinder bound the combustion space of the burner, wherein the hollow cylinder comprises drive vanes and the exhaust gases of the diesel motor and/or the exhaust gases of the burner act upon the drive vanes and wherein the exhaust gases of the burner heat the hollow cylinder up to the combustion temperature of the soot particles. The arrangement can be also made in such a way, that the exhaust gases and/or the combustion gases of the burner flow through bores into the perforated hollow cylinder and exit through the one open end face of the perforated hollow cylinder.

Apparatus for burning the contaminated soot particles in exhaust gases

A method and an apparatus for transporting commodities, especially liquid commodities above their congealing temperature in a tanks or tank containers. At least a partial flow of hot exhaust gases of an internal combustion engine of a tank vehicle or tank container vehicle flows through a heat exchanger through which passes the heat transfer oil in a closed cycle and yields heat to the heat transfer oil and an electrically heated heat exchanger yields heat to the heat transfer oil and the heat transfer oil transfers heat to the commodity through a tank or tank container wall heat exchanger. The heat transfer oil is conducted in a closed cycle in a regulation circuit including the heat exchanger through which the exhaust gas passes and the electrical heat exchanger. The temperature of the heat transfer oil is controlled as a function of a variable reference and the variable reference is preset as a function of the temperature of the commodity to be transported and contained in the tank or tank container, so that the variable reference is always higher than a specified temperature of the commodity to be transported.

The device for the detection and regulation of the planeness of strip-shaped rolled products, especially thin-gage strips (1), for cold rolling mills comprises a planeness measuring system with individual measuring elements, which system includes, for example, a planeness measuring roller (3) composed of individual measuring disks (4) with force measuring transmitters arranged along the circumference. By the planeness measuring roller (3), the strip tensile stress is measured over the strip width (5), from which is calculated the longitudinal distribution (.DELTA.L/L) over the strip width as a characteristic variable for the strip planeness. Regulation of the strip tensile stress is effected by installations for cooling and/or lubrication and/or bending and/or pivoting of the rolls. Measuring units (6) for measuring the position of the strip edges (7, 8) with respect to the planeness measuring roller (5) and detecting the thus-given overlapping of the measuring disks (4), located in the zone of the strip edges (7, 8), of the measuring roller (3), by the strip (1) are arranged on both sides of the traveling strip, for an exact determination of the strip tensile stress in the marginal zones of the strip (1).

Primary components of the conveyor for introducing the thin strip material (2), wound into a coil (1), into the roll nip formed by the work rolls (4, 5) of a four-high rolling mill (3) are a coil cart (6) and a propelling device (7) with a clamping device (8) for seizing the strip feed end (9) of the rolling strip (2). Between a readying station (10) and an unwinding reel (11), a motor-driven coil cart (6) with a hoisting device (14) for lifting and lowering the coil (1) is movable in the strip traveling direction (a) on a track (12). In the readying station (10), backup and pinch rolls (15, 16), adjustable transversely to the strip traveling direction (a), are disposed in opposition on the two longitudinal sides of the coil cart route, for positioning the coil (1) and for threading the strip feed end (9) into a clamping device (8) attached to a transport device (7) with a drive motor, that can be propelled along a longitudinal side of the coil cart route. A clamping device (8) for seizing the strip feed end (9) at the coil (1) is attached to the propelling device (7); this clamping device can be pivoted about a pivot axis (19--19) extending transversely to the strip traveling direction (a) from a receiving position (I) in the range of action of an operator (27) by way of an intermediate position (II) over the coil (1) and a waiting position (III) into a position (IV) for transferring the strip feed end (9) to an introducing device (20) arranged upstream of the rolling mill (3), and vice versa.

The rolling mill stand, for example a four-high rolling mill stand, for strip mills, with adjusting devices acting horizontally and/or vertically on the rolls for roll nip regulation is characterized by a dual bearing for the work rolls (1, 2) in respectively two inner and outer mounting members (5, 6), which latter, for attaining the same change in shape over the strip width, are horizontally adjustable by deflecting the rolls (1, 2) in the horizontal direction by adjusting devices (7, 8), as well as by a positional control of the inner and/or outer mounting members (5, 6). With the aid of the horizontal deflection device, a position-controlled horizontal adjustment of the work rolls (1, 2) can be performed for compensating for the horizontal forces and/or for a strip thickness regulation while maintaining the horizontal bending curve (13) of the work rolls required for planeness of the strip (14).
