Title: Apparatus for relining a bof vessel tap hole
IPC: C21C5/44
Filed: 1974-07-03
Abstract: 1458728 Apparatus for relining a tap hole COMBUSTION ENG Inc 3 July 1974 [5 July 1973] 29499/74 Heading F4B Apparatus for relining a furnace tap hole 12 is mounted on a carriage 16 on tracks 18 and has a boring tool 22 and relining equipment 24 that can be aligned in turn with the tap hole by operation of an hydraulic actuator 19. After the boring and refacing operation is completed the relining equipment is secured hydraulically by clamps 32 (Fig. 4) to the tap hole flange 36. A water cooling nozzle 41 and outer and inner sleeves 44 and 51, which are pneumatically actuated, are made to enter the tap hole. Sleeve 44 carries an umbrella device 49 at the end and relative movement between the sleeves 44 and 51, which is induced pneumatically, erects this device at the inside end of the tap hole. Sleeves 44 and 51 are then moved outwardly to seal the unbrella device against the refractory lining and are locked in this position by a brake cylinder (70), Fig. 8 (not shown). Air cylinders 76 are then actuated which force the ram 86 to the left and refractory slurry 88 is forced into the tap hole cavity 90. The relining equipment 24 includes a resilient spring biased seal member 38 which makes a seal between the tap hole outer face and cylindrical housing 42. Should the umbrella device become jammed on withdrawal after completion of the relining, it may be jettisoned by the shearing of frangible pins 100 and 102 attaching the ends of the sleeves 44 and 51.

Abstract: 638,322. Facilitating flow of material from a hopper; delivering material to conveyers. REDLER CONVEYORS, Ltd. Nov. 5, 1947, No. 29534. Convention date, Dec. 29, 1945. [Class 78 (i)] Arching of material delivered from a bin over the discharge opening is prevented by means including a shaft having lengthwise vanes supported and driven by a universal joint at its lower end and rolling at its upper end along the wall of the bin. In the construction shown in Fig. 1, a tubular shaft 28 carrying flat continuous vanes 30 is connected by a universal joint 29 to a cone 17 adjacent the fixed bottom plate 12 of a bin 10 and driven about a vertical axis through gearing 23, 24 from a sprocket 27. The upper end of the shaft carries a disc 31 which rolls along the inclined wall 11 of the bin. The cone 17 carries fingers 19 which pass across a discharge opening in the plate 12. Gussets 14 reinforce the connection between the walls 11 and the plate 12. In the construction of Fig. 6 the shaft 28 is similarly formed and driven, but the cone 17 is narrower and is attached to a rotating bottom plate 42 which carries the material round to be delivered by a scraper 44 to a shoot 45. Two scrapers 44 may be disposed at diametrically opposite points over the plate 42 to deliver to two belt conveyers running in opposite directions from the bin. The disc 31 may be omitted so that the vanes 30 roll on the wall 11 and shake the shaft 28 as it rotates. The vanes 30 may be curved lengthwise or radially and may be discontinuous and overlapping or otherwise formed.

Oct. 25, 1932, No. 29841. Convention date, Oct. 29, 1931. [Class 103 (i).] A brake-drum has one annular end secured to or integral with a mounting flange which restricts its radial expansion and contraction to a substantial degree, and its other annular end free of such mounting, the portion of the drum at or in proximity to its free end being provided with a rib especially dimensioned so as to make the rigidities of the annular ends of the drum substantially equal. In the construction shown in Fig. 1 the pressedmetal back-plate 10 of the drum is welded to an L-shaped pressed-metal ring 13 cast integrally in the thickened end 16 of the braking annulus 14, the cast metal flowing into dovetailed grooves on the periphery of the ring. A rib 17, dimensions of which are given by way of example, is provided so as to make the rigidity of the free end of the drum substantially equal to that of the end 16. When heated under braking friction the drum curves outwardly due to its central portion being less rigid than its extremities, so that the flat surface of the brake-shoe when applied to the drum contacts first at the drum extremities, as shown in Fig. 6, and then under increasing pressure curves into close contact with the whole of the braking surface. In a modified construction the drum has three ribs 22, 23, Fig. 4, dimensions of the rib 22 being given by way of example. In a second modification the back-plate 10 is curved outwardly at 19, Fig. 3, and fits tightly within a ring 20.
