20110048919 | WALL PROTECTOR FOR A HEATING WALL HEAD BETWEEN TWO OVEN CHAMBER OPENINGS OF A COKE OVEN BATTERY - The invention relates to a wall protector for a heating oven head ( | 03-03-2011 |
20130313101 | ADJUSTABLE CHARGING HOLE CLOSURE FOR CHARGING THE COKING OVEN CHAMBERS OF A COKING OVEN BATTERY - An adjustable chargehole closure for adjusting the closure cover of a charging hole in a coking oven chamber. The adjustable chargehole closure has as an inner frame for a closure cover, and the frame can be rotated both with respect to the closure cover and with respect to an outer frame, designed asymmetrically with respect to a vertical plane, so that the closure cover is displaced along a longitudinal axis when the inner frame is rotated in the horizontal plane. The position of the charging hole opening and the closure cover present therein on the ceiling of a coking oven chamber can thereby be changed without requiring construction measures on the ceiling of a coking oven chamber. The capability is in particular advantageous in order to match the position of the charging hole cover to the precise charging position of the charging machine. | 11-28-2013 |

20090029210 | Low-Temperature Fuel-Cell Stack and Method of Operating Same - The invention relates to a low-temperature fuel cell stack comprising a specific device for the supply of fuel. Said low-temperature fuel cell stack is characterised in that, in addition to the central fuel supply device, it comprises a supply or storage device for a liquid fuel, and a plurality of separately controllable dosing devices that lead into the central fuel supply device, especially respectively upstream of a distribution channel to the individual cells. Controllable valves, controllable piezoelectric pumps or thermally controllable supply elements are suitable as dosing devices. The invention also relates to a method for operating one such low-temperature fuel cell stack, which advantageously enables a defined concentration of fuel, or a defined humidity of the oxidation medium, to be adjusted at certain points in the fuel cell stack, especially on the inlet for the individual cells. | 01-29-2009 |
