The construction kit further contains a frame to be fitted into the first door field, which can be detachably connected to the bodyshell and which has at least one window bar, which, in conjunction with the door columns, delimits a first window field for fitting the first window in the fitted state of the frame in the first door field.

Abstract: A method for generating heat energy in a power plant by burning a carbonaceous fuel in a combustion chamber of the power plant and a system for carrying out the method is described. A combustion chamber is fluidly connected to a membrane chamber that includes a membrane operating at a temperature between 600 and 1000° C. The combustion chamber receives a cleaned flue-gas oxygen mixture for combustion from the membrane chamber. Oxygen from heated air passes through the membrane in the membrane chamber to the permeate side of the membrane, where it is mixed with cleaned heated flue gas and the resulting gas mixture is fed to the combustion chamber. Flue gas removed from the combustion chamber are cooled, cleaned and heated as described herein and recirculated to the membrane chamber.

Abstract: A mouthpiece has a bite-off-prevention feature. The mouthpiece has been manufactured from an elastomeric parent material with at least one first component, where a reinforcing component embedded within the parent material forms the bite-off-prevention feature and derives from the same group of substances or group of materials as the first component. The reinforcing component is preferably composed of fibers.

Abstract: Provided is a power plant for generating electrical energy comprising a combustion chamber for producing steam, at least one downstream flue gas purification stage, a separation stage for CO2, a recycling circuit for the flue gas, and a high-temperature O2 membrane, which is connected upstream of the combustion chamber. The high-temperature O2 membrane has an inlet and an outlet on the feed side which are thermally coupled by way of a heat exchanger. On the permeate side, the high-temperature O2 membrane has only an outlet which is connected to the combustion chamber and/or the flue gas recycling circuit and a means for cooling and/or compression which is disposed in this outlet.

Abstract: A composite membrane for selective gas separation, comprises a layer system having a continuously porous, mechanically stable carrier layer, which has an average pore size in the ?m range, further having at least one continuously porous intermediate layer, which is disposed on the carrier layer and has an average pore size in the range of 2 to 200 nm, and further having a gastight functional layer, which is disposed on the intermediate layer and is made of a mixed-conductive material having a maximum layer thickness of 1 ?m. The carrier layer comprises a structural ceramic, a metal, or a cermet and has a layer thickness of no more than 1 mm. The intermediate layer is present with a total layer thickness of no more than 100 ?m and has an average pore size in the range of 10 to 100 nm. The functional layer comprises a perovskite, a fluorite, or a material having a K2NiF4 structure, such as La1-xSrxCo1-yFeyO3-8 (LSCF).

Abstract: A combustion system comprising a burner and a combustion chamber, is connected by way of a line to a membrane unit having a high-temperature membrane for extracting the combustion oxygen from the air, the membrane unit having a feed line for a flushing gas on the permeate side. The combustion system further comprises a circulation element for recirculated flue gas, a heat exchanger being disposed upstream of the membrane unit inside the flue gas line. Disclosed is a method for operating this combustion system, in which carbon-containing fuel is burned in an oxygen-flue gas atmosphere, and in which the oxygen for combustion is produced from air by means of a membrane unit comprising a high-temperature membrane, and in which the flue gas is in part recirculated.

Abstract: The invention discloses a method for operating a communication terminal comprising a receiver chain (EK) with at least one receiver component (RXD) and with an amplifier device (LNA) connected upstream thereof for receiving broadcast radio signals transmitted in first time periods in a predetermined frequency band, and also a transmission device (SEM) for transmitting radio signals. The method has the following steps. First of all, the noise occurring upon transmission of the radio signals in the frequency band of the receiver chain is measured in the receiver chain and then the gain of the amplifier device is set on the basis of the measured noise such that a maximum signal level on the receiver component is not exceeded.

Abstract: Electrode columns made from carbon and graphite are screwed together from individual elements, for example, the electrodes and nipples. The elements have directionally structured contact surfaces. Such a structure of the contact surfaces gives rise to the elements of a column demonstrating increased resistance to loosening after intensive machine screwing or screwing applied by hand, which, therefore, is often inadequate, whereby a higher level of operational reliability is achieved, in particular, in the case of electrode columns that are screwed together by hand.

Abstract: An electrode connection includes coated contact surfaces in differently constructed electrode strings formed of carbon and graphite being provided with sliding layers. With the aid of these sliding layers, the elements of a string can be screwed more firmly against one another, with the result that a higher release torque and higher operating reliability are achieved.
