摘要： PROBLEM TO BE SOLVED: To improve cost effectiveness and grade by subjecting the weakly acidic pulp obtd. by mixing the thickened matter of graphite of a high carbon content and a dilute acid to attrition, thereby enhancing a permissible recovery rate and minimizing flake sizes. SOLUTION: The thickened matter 13 of graphite obtd. by mixing kish 10 of a desired graphite rate and a suspended assistant in a tempering tank 11 is thickened in a coarse flotation tank 13, by which the thickened matter 14 contg. graphite carbon is obtd. The +200 mesh fractions obtd. by sieving the thickened matter 14 by a wet process screen are subjected to light milling with a pebble mill 20 and are then sieved by a wet process screen 22, by which the +200 mesh" fractions 23 are obtd. The weakly acidic pulp 26 obtd. by mixing the fractions 23 and the dilute acid 24 in a tank 25 is mixed with an adjuvant 28 with an attrition device 27 and after the impurities remaining in the graphite are removed, the attrition is so executed that the greater part of the flaky graphite remains on the +100 mesh. The weakly acidic pulp 26 is then neutralized, by which the flaky graphite is obtd.

摘要： PROBLEM TO BE SOLVED: To increase the usable quantity of molten metal discharged from a vessel by arranging a pocket block reservoir having a specific % of the whole vol. of a metallurgical vessel and containing a tapping hole for discharging the molten metal from the metallurgical vessel, arranged at an inclining lower surface. SOLUTION: The pocket block reservoir signifies the range surrounding a pouring hole on the bottom part in the metallurgical vessel having a refractory lining bottom and has the vol. of = about 3 deg.. By this structure, when the vessel is almost empty, the range for small pool which increases the depth for storing the residue of the molten metal and slag, is obtd.

摘要： PROBLEM TO BE SOLVED: To improve a high temp. lining of the metallurgical container having an inclined bottom part and to reduce a working hour and a maintenance cost required for lining. SOLUTION: The refractory horizontalizing assembly is of a precast module type to be mutually connected. The precast modules correct an inclined bottom part of the metallurgical container. At least one of the precast modules are respectively arranged to two partial rings. The respective partial rings essentially have a shape mirror image relation each other. A height of the horizontalizing assembly is essentially/uniformly changed from a high point i.e., an end part 40, which connects the two mirror image relation parts, to a low point i.e., which is apart from this point by an circular arc of 180 deg. and again connects the two mirror image relation parts. A height of the respective refractory precast modules, a tapered shape a little, is constituted so that the end parts (40 or 41) of the respective precast modules have the same height as adjacent end parts (41 or 40) of adjacent the precast modules.

摘要： A removable reference laser target for detachable installation at identified target positions on the exterior of a refractory lined high temperature molten metal vessel (10). The target includes a generally rectangular target plate (20) with an elongated slot (21) generally paralleling the long dimension of the rectangle. On the same side of the plate but on opposite sides of the slot are two mounting and adjusting bolts (22, 23) for detachably affixing the target at an identified position on the exterior surface of the vessel. Extending essentially at right angles to the major rectangular surface of the plate is an extension (25, 26) the free end (26a) of which contacts an external reinforcing member and assures precise re-location of the target to be used with laser equipment to provide a reference for determining thickness and/or condition of a refractory lining of the vessel.

摘要： A ladle brick leveling set (20, 21) for high temperature molten metal ladles in which specially shaped refractory bricks are disposed in a slightly sloping geometrical configuration so as to compensate for a sloping bottom (19) of a high temperature molten metal ladle (11). The bricks are disposed in two partial rings (20, 21) each of which is essentially a mirror image of the other so that the height of the leveling set (20, 21) varies substantially uniformly from a high point where the two mirror image portions join (26a, 26b) to a low point 180 degrees of arc displaced therefrom, where the two portions again join (25a, 25b). Each of the refractory bricks has a slight taper in height so that the ends of each brick are the same height as the juxtaposed ends of the adjoining bricks.

摘要： A gear shifting power tool (10) includes a rotatably-driven, torque-responsive, gear shift device (30). Rotatably-driven, torque-responsive, gear shift device (30) may include drive spindle (38), plunger (54) positioned within drive spindle (38). Drive spindle (38) has first hole pair (44) and second hole pair (46) in which first ball pair (48) and second ball pair (50) contact plunger (54). Drive clutch member (32) is drivably engaged to drive spindle (38) through ball screw arrangement (64). Drive clutch member (32) disengages from driven clutch member (34) in response to a resistive torque overcoming torque spring (40). Inertial device (62) forces first ball pair (48) into one end of plunger (54) which forces plunger (54) towards reset spring (60). Plunger (54) forces second ball pair (46) into inner axial groove (36) of drive clutch member (32) and prevents drive clutch member (32) from engaging driven clutch member (34) until all rotation ceases.
