Abstract: Coke oven doors and more particularly coke oven doors having a unique and novel spring arrangement for maintaining the knife edge of the sealing element in sealed relation to the face of the coke oven door jamb, an improved sealing arrangement at the leveler door, scalloped cutouts in the main frame components to increase efficiency of heat dissipation, a manual adjustment structure incorporated into the main door frame to provide more positive and controlled flexibility of the main door frame and the provision of cuts in the door frame and the manner in which the diaphragm plate is connected to the refractory to provide space for the door frame to flex when adjustments are made.

Abstract: A solar venturi turbine includes an upwardly oriented venturi tube supported by a venturi support skirt. The venturi tube includes a tapered thermopane glass enclosure which allows sunlight to project therethrough and impinge on a tapered centrifugal fan fronting the thermopane enclosure and mounted within the venturi tube. The fan vanes are configured to spiral radially outwardly in a clockwise direction when viewing the fan in top plan. The fan vanes have a cross-sectional profile approximating an inverted L. Located above the centrifugal fan in the neck of the venturi tube is a high velocity fan. A high pressure compressor is mounted above the high velocity fan, and finally a turbine is mounted above the high pressure compressor. A venturi tube outlet flares outwardly directly above the turbine and is mounted to the venturi tube. The turbine is connected to a shaft to drive an electrical generator thereby producing electricity.

The turbine is connected to a shaft to drive an electrical generator thereby producing electricity. The sun's rays heat the air within the thermopane glass enclosure causing the reduced density air to rise within the venturi tube and propel the centrifugal fan.

Abstract: A coke over door jamb cleaner utilizing a unique supporting arrangement, scraper-type cleaning elements and a floor or hearth cleaning tool for effectively cleaning the sealing surfaces of a coke oven door jamb and the floor or hearth of the coke oven adjacent the door.

Abstract: A retrofit coke oven door seal to replace existing coke oven door seals that have become ineffective due to normal use. The retrofit coke oven door seal includes a leaf spring and seal arrangement and a unique mounting structure to enable the existing seal on a coke oven door to be easily removed and replaced by the present invention without modification of alteration to the door body or the existing refractories thus making improvements (in emission control) on existing doors by using a relatively simple structure which is cost effective. The retrofit seal for coke oven doors includes a mounting structure attached to the periphery of the diaphragm plate normally provided on a coke oven door together with fastening devices securing a leaf spring and seal assembly in a manner to enable easy removal and replacement thereof if necessary.

Abstract: A mine supply car has fixed, rail-engageable wheels, and adjustable selectively useable road wheels mounted in elongate frames along the sides of the car. The road wheels are mounted on pivot arms for swinging movement between raised inoperative positions and lowered operative positions. The arrangement allows the car to be converted between rail and road use by relatively effortless manual movement of the road wheels.

Abstract: A coke oven door construction, adaptable for either the pusher side or the coke side of the oven, has a diaphragm arranged so as to exert an even pressure all around the door and associated jamb when the door is locked in the jamb by a suitable locking device. After the door has been locked in place, air is connected to the bottom of the door so as to permit injection of a mixture of air and a suitable anti-stick agent all around the door diaphragm and onto the sealing surface of the associated jamb. The anti-stick agent keeps carbon and other foreign matter from sticking to the diaphragm and jamb surfaces. Further, if a fire occurs between the sealing surfaces, it can be extinguished by connecting the air to the doors. The air mixed with the anti-stick agent is preferably preheated before it reaches the jamb surface so as to prevent warping of the jambs.

Abstract: An upstanding support is provided and a carriage is mounted on the support for vertical reciprocation between predetermined upper and lower limit positions on the support. A jamb cleaning head is mounted on the carriage for vertical reciprocation therewith along and for cleaning an adjacent upstanding jamb portion. A support structure stationarily positioned relative to an associated coke oven jamb and mounting structure is provided for supporting the upstanding support relative to the stationary support structure for vertical shifting relative thereto. First drive structure is connected between the support and the carriage for driving the latter along the former between the aforementioned limit positions and reversible second drive structure is connected between the stationary support structure and the upstanding support for reversibly variably shifting the upstanding support relative to the stationary support structure.
