Abstract: The invention relates to a rear crash element for the rear bumper of a motor vehicle in the area of the number plate recess, having an impact element seated on the crossbeam of the motor vehicle, behind which, with respect to the driving direction of the motor vehicle, a shock absorbing element is arranged. The shock absorbing element is arranged behind the bumper cladding and is covered by a plastic covering, such as a horn cladding or the like.

Abstract: An air-directing component (10) of a motor vehicle has an installation surface (18) that bears against an outer side (20) of the front end (12) of the motor vehicle. Hook-shaped projections (14.1, 14.2) protrude from the installation surface (18) and have dimensions which are matched to dimensions of the recesses (16.1, 16.2) in the front end (12) in such a manner that be pushed into recesses (16.1, 16.2) of a body front end (12) of the motor vehicle. Each projection (14.1, 14.2) reaches through the recess (16.1, 16.2) and engages behind an edge (26) of the recess (16.1, 16.2) on an inner side (28) of the front end (12). The shape and arrangement of the projections (14.1, 14.2) permit the projections (14.1, 14.2) to be pushed transversely with respect to a longitudinal axis of the motor vehicle into the recesses (16.1, 16.2).

Abstract: The invention relates to a rear crash element for the rear bumper of a motor vehicle in the area of the number plate recess (3), having an impact element (7) seated on the crossbeam (4) of the motor vehicle, behind which, with respect to the driving direction of the motor vehicle, an impact-receiving element (8) is arranged. The element (8) is arranged behind the bumper cladding (1) and is covered by a plastic covering, such as a shell cladding (2) or the like.

Abstract: A coolable arched roof for a high-temperature melting furnace having a furnace interior. At least the following layers are present on that side of a layer of refractory bricks, which is remote from the furnace interior: a sealing layer, which is used to seal the furnace interior against the leakage or penetration of gas; an insulation layer having a thermally insulating action; and a cooling layer, which is designed to carry a cooling fluid. The arrangement of layers results in an increased gastightness and prevents premature aging of the refractory bricks.

Abstract: The bumpers of motor vehicles nowadays are being used to an increasing extent to carry components of small size in which their position on a bumper is especially advantageous for their operation due to its exposed location. For example, it is known to build into the bumpers of vehicles flashers, parking lights and especially distance sensors (parktronic sensors, abbreviated PTS) which detect the distance from other vehicles or obstructions and are designed as parking aids. The components must be mounted such that when the bumpers are affected, especially by mechanical shock, any loosening or dropping out will be impossible. At the same time the mountings must be able to be made simply and inexpensively. It is therefore proposed according to the invention that the tongues be affixed by feet to the bumper, or in case of a bumper of modular design, to one of its modules, and be positioned opposite the opening.

Abstract: Sewage sludge from municipal and industrial sewage systems can be incinerated in conjunction with the incineration of refuse in a refuse incinerator as environmentally safely as possible, with a favorable energy balance and low expenditures for technology and equipment. The sewage sludge can be fed into a rotary tubular kiln, while in a countercurrent, flue gas from a refuse incinerator can be passed through the rotary tubular kiln. The resulting vapors from the sewage sludge incineration can then be injected back into the refuse incinerator for afterburning, while the components of the vapors are useful for the reduction of the formation of nitrogen oxide during the incineration of the refuse.

Abstract: In refuse incineration, it has been determined that the legal requirements governing refuse incineration can be more easily met by maintaining a uniform depth of charge on the grate. The charging of the refuse and the transport speed of the charge produced by movable refuse feeders can be regulated as a function of the quantity of refuse in the incinerator or in its individual zones. The load of the drive mechanism can be used for measurement and control purposes for maintaing a uniform refuse depth.
