摘要： A coke oven machinery positioning and spotting system comprises system characteristics mapped in a process memory and system dynamics controlled by a central processing unit and a sensing mode. The system results in the automatic control of machine travel, positioning and spotting, and interlock against further travel until a command signal is given to start a new sequence.

摘要： In a blast furnace tuyere, operating at subsonic velocity, an inner cylindrical air conduit is reduced to a frusto-conical conduit near the tuyere nose. A water cooled, pear-shaped, hollow body within the tuyere is held suspended by a bracket, in a centered position, where it exerts minimum interference with the pressurized fluid flowing partly through it and partly around it, having a cylindrical smaller conduit in such body and an annulus between the outer perimeter of such body and the inner wall of the cylindrical or conical conduit of the tuyere.The bracket slides parallel to the tuyere axis in guides, which are integral parts of the tuyere proper, thereby securing a centered position whenever the bracket is approaching to or retreating from the tuyere nose. The area of the annulus is uniformly decreasing when the body on the bracket is moving toward the tuyere's nose; consequently, the air jet velocity through the tuyere is increased but, by virtue of the diverging-converging inverse annular nozzle between the frusto-conical conduit and the pear-shaped suspended body, a near parallel air current with optimum thrust can be maintained at any position of the body.A driving mechanism serves to actuate the movement of the bracket and body; the driving mechanism being externally mounted at an accessible location.

摘要： A cylindrical drum having a lining spaced apart from the shell of the drum is rotatably mounted on a frame movable on rails along the coke side of a coke oven battery. A fume shield is fixed to the frame and covers openings in the shell and lining through which hot coke passes, when pushed from a coke oven chamber. A hood is fixed to the structure supporting a coke guide and has a movable portion that coacts with the rotatable shell when coke gravitates into the shell. The drum is rotatable to several operative positions.

摘要： The present invention is an improved pellet mill die having tapered grooves along each side of the compression surface of the die. The tapered grooves reduce the stresses at the maximum stress areas and thus control the breakage of metal between the first rows of holes and the inner edges of the grooves.

摘要： A coke oven regenerator checker brick which incorporates, with the principle of maximization of heat transfer, the ability to minimize pressure differential within such a regenerator, while providing facility of inexpensive manufacturing techniques. A coke oven checker of standard overall dimension incorporates wave-like corrugations, for maximum surface area exposure, and sufficient web thickness to enable manufacture by the conventional re-press method which is the most economical commercially available method for manufacturing refractory coke oven checker brick.

摘要： An improved web guide structure of the self-adjusting type for a corrugated web single-facer machine including a plurality of laterally spaced guides for continuously and yieldably urging a corrugated medium web against a lower corrugator roller, a support rigidly mounted to the single-facer for pivotally supporting the guides, and a gravity-actuated and adjustable biasing means for urging the guides against the corrugated web at preselected pressures. The guides preferably include a trailing guide portion that remains in engagement with an adhesive applicator roll when the roll is moved out of engagement with the corrugated web to maintain alignment of the guides with the roll. Springs may also be used in conjunction with the support to apply greater or lesser pressure to all of the guides simultaneously.The method includes applying pressure at selected lateral locations across the width of the corrugated web, such pressure being yieldably applied to each of the guides by an elastic member or by gravity-actuated counter-weights.

摘要： Isotropic carbon fibers are disclosed and a method is disclosed for making them from liquid hydrocarbon distillates comprising reacting the distillate with elemental oxygen to produce a pitch-like product which will yield isotropic carbon upon subsequent carbonization, forming the pitch-like product into a filament and carbonizing the filament in an inert atmosphere at temperatures in excess of 800.degree. C wherein the distillate is reacted with the oxygen until at least 0.5 standard cubic feet of elemental oxygen is reacted per pound of distillate.
