Abstract: The invention relates to a device and a method for producing clinker from raw cement material. The raw cement material is preheated in a preheater, is precalcined in a calcining apparatus, is completely burned in a sintering furnace, and is finally cooled in a cooler. Tertiary air of the cooler is fed to the calcining apparatus while eliminated dust is thermally treated in a dust burning reactor with the aid of combustion air and fuel. At least some of the tertiary air is fed to the dust burning reactor as combustion air while the dust that is to be treated and the combustion air penetrate the dust burning reactor in the same direction of flow.

Abstract: An antenna transmission control device has a base-station-side and an antenna-side multiplexer circuit. There is an alternating protocol transfer between these two multiplexer circuits to control components close to the antenna. The current-alarmed or protocol-alarmed signals present at the antenna-side terminals of the multiplexer provided on the antenna side can be measured or detected by the multiplexer circuits and supplied to the transmission link together with a terminal-dependent or load-dependent protocol.

Abstract: An aerial transmission control device has a converter circuit. The converter circuit has at least one connection on the base station side, and at least one connection on the aerial side. The converter circuit is constructed so that when a load is connected, a power drawing which can be ascertained via the connection on the aerial side is measured in the converter, and so that at at least one connection on the base station side, the measured power drawing is fed in in the form of a protocol signal.

Abstract: The invention relates to a plant and to a method for the production of cement clinker from cement raw meal, the cement raw meal being preheated in a preheating zone, precalcined in a calcining zone, completely burned in a sintering combustion zone and cooled in a cooling zone, solid fuels additionally being burned in an additional combustion region, a firing region being used in the additional combustion region, the solid fuel being introduced into the firing region where it forms a fuel bed over which a supplied oxygen-containing gas flows, the resulting combustion products being removed via a discharge opening and being used in the production of cement clinker. The fuel is supplied via a conveyor device arranged outside the firing region, in such a manner that it moves the fuel bed that is present in the direction towards the discharge opening.

Abstract: The system according to the invention for producing cement clinkers from raw cement mix is composed substantially of a pre-warmer for pre-warming the raw cement mix, a calcination device for pre-calcining the pre-warmed raw cement mix, a sintering kiln for firing the pre-calcined raw cement mix to form cement clinkers, and a cooler for cooling the fired cement clinker. Additionally provided between the cooler and the calcination device is a tertiary air line via which tertiary air is supplied to the calcination device. The calcination device is additionally traversed by the waste gases of the sintering kiln and has a calcining nozzle in its inlet region. Also provided are means for setting the cross section of the calcining nozzle, which means are formed by at least one element which is arranged in a rotatable or pivotable fashion in order to set the cross section and which is exposed to the waste gases of the sintering kiln.

Abstract: An injector housing (1) of the injector has an indentation (2) in which a part of an actuator housing (4) of the injector is located. A floor of said indentation (2) is formed by a peripheral support surface (3) for the actuator housing (4). A bottom surface of the actuator housing (4) is oriented towards the support surface (3) and has a peripheral recess (11). This recess (11) is such that the bottom surface of the actuator housing (4) has at least one peripheral projection (12), which is oriented towards the support surface (3) and is adjacent to the support surface (3). A seal (13) for preventing leakage along interfaces between the injector housing (1) and the actuator housing (4) is locate din the recess (11) and is adjacent to the support surface (3).

Abstract: An actuator with a top plate comprises at least one duct opening for a respective electric contact pin. A contact stud carrier with a contact stud is placed over the contact pin. To prevent the possible ingress of plastic into the duct opening between a gap (s) between the contact stud carrier and the top plate during extrusion coating of the actuator or its top plate, according to the invention it is proposed that a sealing washer be located onto the open side of the duct opening of the top plate to provide a hermetic seal. As a result, the contact stud carrier can advantageously always be arranged independently of the thickness of the sealing washer such that a specified actuator length (L) can be precisely maintained. This simplifies the production process for the actuator and reduces its production costs.
