Abstract: A process is disclosed for regulating the gas pressure in the retort of a coke oven. Pivotable cup valves arranged in the elbows of the ascending pipe are actuated as throttling members according to the pressure curve resulting from gas formation from the coal to be cokefied. Throttling of each individual retort is effected by varying water supply, thus regulating the extent of submersion in water, and regulation follows actual pressure conditions in the retort of the coke oven.

Abstract: Apparatus for measuring the temperature distribution along the inside walls of narrow, shaft-shaped spaces such as heating flues of coking and similar ovens using a radiation pyrometer with an evaluating arrangement, whereby a radiation optical system is disposed at one of the ends of the space and contains a mirror tiltable about an axis, for optical coverage of the entire length of the space and forwarding of the detected radiation into the path of rays to be evaluated, as well as a positioning arrangement for tilting the mirror over the area to be optically covered. Therewith a fixed mirror is arranged after the tilting mirror and the path of rays to be evaluated is focused to the end of a photoconductor, which, in a transportable and coolable measuring lance, is directed to an evaluating arrangement. The measuring lance can be coarsely and finely positioned by means of a carriage arrangement.

Abstract: The shed or hall for a set of coke ovens defining a door region for supporting a coke transfer carriage, a quenching region for supporting a quenching carriage, and a washer region, comprises a central upright partition disposed between the quenching and washer regions and having its top portion bent about 180.degree. to form a guiding surface communicating with the washer region, a roof supported above the respective regions and accommodating an upper guiding metal sheet and an intermediate metal sheet forming together with the guiding top portion of the upright partition two (2) fume discharging channels communicating respectively with the door region and the quenching region and at the other end, with the washer region.

Abstract: An infrared heat-image camera is aimed at a hot surface not perpendicular thereto but instead in a direction almost parallel to the surface, presenting to the camera a heat image of the surface not cartesian but instead highly distorted in accordance with the laws of optical perspective. The camera's output data is correspondingly non-cartesian and distorted with respect to organization and content, but the data is applied to a computer which transforms it to cartesian organization and corrects content, and then a corrected cartesian display is generated, simulating the heat image which would be presented to a perpendicularly aimed camera. Alternatively, the camera's scanning mechanisms are programmed to follow a non-cartesian scanning schedule, the geometry of which itself causes the camera output data to have the cartesian organization of a perpendicularly aimed camera.

Abstract: A heating wall of a coking oven, particularly a horizontal coking oven, separates the coking chamber of the coking oven from the heating flues through which a heating medium flows to heat a charge of coking coal which is contained in the coking chamber. The heating wall is provided with a plurality of individual compartments which are separated from each other and also from the coking chamber and from the heating flues, the compartments being situated between the coking chamber and the heating flues and increasing the rate of heat transmission through the heating wall. Depending on the desired heat-transmission properties of different portions of the heating wall, the compartments may be distributed either uniformly or nonuniformly, or may have the same or different dimensions. The heating wall is constituted by refractory blocks and the enclosed compartments are provided in these refractory blocks.

Abstract: A larry car, a quenching car, a pusher and other such accessory machines travel along the length of a coke-oven battery. Each coke oven is provided with coded structure absolutely indicative of the oven-number of the oven within the battery. The travelling accessory machines are provided with code readers which sense the coded structures and transmit oven-number feedback signals to a central control station. The travelling machines also transmit operation-completed signals upon completion of the individual operations of charging, pushing and the like. A programmed control system at the control station transmits travel-command and operation-command signals in preprogrammed sequences, but the transmission of these command signals is dependent upon the reception of predetermined feedback signals, which establish interlocks serving as conditions precedent to the travel of accessory machines and to their performance of individual operations.
