Method for improved distillation of ammonia from weak ammonia liquor

Abstract: Fouling of an ammonia still, used for removal of ammonia from weak ammonia liquor derived from a coal coking operation, is alleviated by pre-precipitating insoluble calcium salts from the ammonia liquor by treatment of the liquor with lime prior to introduction into a single-leg still.

Coke quenching car closure mechanism

Abstract: A coke quench car having a slanted bottom and discharge opening in one wall is provided with a movable grate at the discharge opening to drain water and retain coke. A door outboard of the grate closes the discharge opening in a substantially liquid-tight condition and accumulates quench water in the car to submerge the coke. Means are provided for selectively opening the door to drain only water at the quench station and for later opening the grate to discharge the quenched coke at the coke wharf. A second embodiment provides a tilting bottom coke car with a first sealing means for sealing the car in substantially liquid-tight condition to accumulate water and submerge the coke. A second sealing means are provided to permit the floor to be tilted to a liquid discharge position to drain only water. Means are provided for tilting the floor between an open and closed and intermediate liquid discharge position.

Load indicating washer and fastener assembly including such load indicating washer

Abstract: A non-heat treated load indicating washer (10) for visually indicating the magnitude of compressive force applied by a fastener (34, 36, 46) to opposed surfaces of the washer and a fastener assembly including such load indicating washer. The washer has a number of integral protuberances (14) struck from the washer and spaced from the inner (16) and outer (18) peripheries of the washer, each protuberance has a truncated concave basal surface (24) lying within the confines of the washer and a raised convex surface (32). The number and size of the protuberances (14) depend on the compressive force such that the protuberances will deform into the washer when the compressive force reaches a predetermined magnitude.

Particulate size separator and method of operating

Abstract: Size separation is effected upon coal, ores, pellets of various sizes and other particulates by depositing the particulate material in an inclined rotating separator vessel having a flat bottom with a central orifice and peripheral sidewalls. As the separator vessel rotates the particulates are carried upwardly and churned by the movement of the vessel. The larger particulates accumulate upon the top of the body of particulates in the separator and eventually overflow over the lip of the vessel while the smaller particulates accumulate in the lower portion of the body of particulates and are then carried up by the movement of the vessel and pass out of the vessel through the central orifice.
