Abstract: An upright apparatus for cooling high pressure gases with a high dust component includes a radiation/convection cooler with longitudinally extending heat exchanger elements and a convection cooler follows the radiation/convection cooler on the gas side. As distinguished from known devices for the cooling of high pressure gases, the apparatus provides a largely uniform distribution of the gas at the cooling elements and hence a uniform thermal load of the individual elements in the radiation/convection cooler. A uniform cleaning of these cooling elements and easy removal of the dust from the cooling surfaces of these cooling elements is made possible, in order thereby to ensure a good heat transfer. The radiation/convection cooler heat exchanger elements are combined in finned tube walls forming lanes between them, which walls extend from one inner wall section to the opposite inner wall section.

Abstract: A truck, especially a large capacity vehicle or tractor semi-trailer combination including a motor-steering unit, which essentially includes the motor, the transmission, the axles, the wheels, and where applicable, a fifth wheel for a semi-trailer; a payload carrier or semi-trailer; and at least one vehicle control cab. The vehicle control cab and other additional structures respectively form separate units which are arranged on top of one another in any desired order and are firmly interconnected. The lowermost respective unit may be mounted on the motor-steering unit.
