Abstract: A method for device-independent access to multimedia contents is specified in which a marker information item is provided by a first terminal. The marker information contains at least one marker in a multimedia content. The marker information is stored and a request for access to the multimedia content is provided. A transmission information item is ascertained on the basis of the request for the purpose of transmitting the multimedia content starting from the at least one marker to a second terminal.

Abstract: In this process for the removal of residue particles from a discharge opening of a pressurized gasification reactor according to the fluidized bed or flue dust principle the residue particles are removed by a worm conveyor. To avoid pressure fluctuations in the actual gasification process and to perform a continuously operating residue removal not susceptible to disturbances the discharge opening of the worm conveyor housing is provided with an adjustable pressure device for exerting a closing pressure on a closing element.

Abstract: Moist bulk coal is supplied into a fluidized bed drier into which is introduced a first heat carrier gas to thereby dry the moist coal to form dried coal. The dried coal is discharged from the drier and is transferred to a generally horizontal bulk material conveyor. A second heat carrier gas is injected through the bottom of the bulk material conveyor, thereby transporting the coal generally horizontally and preheating the coal to form preheated coal. The preheated coal is then discharged from the bulk material conveyor and is filled into a selected charging opening of a coke oven battery.

Abstract: Small, pourable particles of comminuted coal for coking purposes are gravity-discharged into a stream of hot gas flowing upwardly in a flight stream tube, in a direction inclined and generally opposite to the gas flow direction. Just prior to entry into the gas stream the particles are fluidized so that, on being entrained by the gas stream, they will become uniformly distributed throughout the cross-section of the same. A method and an apparatus are disclosed.

Abstract: A process and apparatus for the dry cooling of coke involves the provision of a vessel having therein first and second zones in full communication with each other. Hot coke from a coking operation is introduced into the first zone and is passed through the first and second zones. Raw coke oven gas from the coking operation is introduced into the first zone, thereby reducing the temperature of the coke, while cleaning the raw coke oven gas to form cleaned coke oven gas. The cleaned coke oven gas is removed from the first zone, cooled, and then directly or indirectly utilized as a heat carrier gas introduced into the second zone to therein further reduce the temperature of the coke. The thereby further cooled coke is removed from the second zone.

Abstract: A method and apparatus for the dry cooling of coke is disclosed wherein a cooling gas is routed through a coke charge by means of a distributor or manifold disposed in the bottom of a vertical cooling chamber. The gas passing upwardly through the coke charge is heated by the hot coke. A temperature sensor is provided in the discharge line for the heated gas from the coke cooling chamber, and the distribution and flow rate of the cooling gas introduced at the bottom of the chamber is controlled thereby to maintain a predetermined temperature of the discharged gas. A further embodiment includes multiple gas discharge lines located at different levels of the coke charge. Since the temperature of the gas discharged varies with the level from which the gas is withdrawn, controlled combination of the various discharge flows provides an additional means for producing and maintaining the predetermined temperature of the combined gas discharge.

Abstract: A method and an apparatus are described for preventing the unintentional introduction of coal from a supply into a coke oven which already contains a charge of coal or coke. An obstruction sensor is lowered through a charging hole in the ceiling of the oven; if it encounters an obstruction, such as a charge of coal or coke in the oven, it triggers a signal which blocks any discharge of coal through the charging hole into the oven.

Abstract: Apparatus for the production of ammonia synthesis gas by the catalytic cracking of coke oven gas in the presence of water vapor and air is disclosed. The apparatus includes concentric inner and outer pipes, a first annular reaction zone between the pipes and a second reaction zone inside the inner pipe, both zones containing a catalyst. The purified coke oven gas along with air and water vapor is introduced into the interior of the outer pipe, i.e., into the first reaction zone at one end. The gas flows along the length of the pipes and then into the inner pipe, i.e., the second reaction zone, through a number of openings in the end of the inner pipe opposite the end of the outer pipe where the coke oven gas was initially introduced. The gas then flows along the length of the inner pipe to the opposite end where the cracked gas is removed.

Abstract: Coal is passed in a two-stage process through a drying and heating zone. The coal coming from the drying zone is separated from the heat carrier gas which is then passed into the atmosphere after going through an electrodust separator. The dried coal is delivered into the heating zone. The hot gas for the heating zone is furnished by a combustion device. The exhaust gas from the heating zone is separated from the heated coal which is recovered while the exhaust gas is passed back into the drying zone. Part of the hot combustion gas coming from the combustion chamber is branched off and passed into the exhaust gas coming out of the drying zone either directly behind the drying zone or behind the separator for separating the dried coal from the exhaust gas. The temperature of the exhaust gas from the drying zone is thus prevented from sinking below the sulfuric acid dewpoint or water vapor dewpoint which might result in corrosive damage to the apparatus, particularly to the electrodust separator.
