Abstract: A process for producing a metal matte from a nonferrous metal-containing sulfide mineral concentrate in a horizontally disposed furnace wherein small sulfide particles are separated from the concentrate, compacted and introduced into the furnace along with the remainder of the concentrate; a melted iron sulfide-rich concentrate is spread onto the slag adjacent the introduction of the sulfide mineral concentrate; and a metallic iron-rich material containing carbon or silicon is spread onto the slag at a location adjacent the introduction of the melted iron sulfide-rich concentrate but spaced from the slag discharge of the furnace, such that a high-grade nonferrous metal matte is produced and the loss of nonferrous metals is averted.

Abstract: A sprinkler burner and method for injecting solid particulate material and a gas into a reactor as a paraboloidal suspension. Means are provided to introduce the gas tangentially into an outer cylindroidal member, comprising a slot-like gas inlet in the cylindroidal member and a spiral shaped conduit communicating with the slot, such that the gas is directed around the periphery and downward between the outer cylindroidal member and an inner tubular member through which the solids are fed. The gas entrains the solids emitting from the inner tubular member and spreads the solids tangentially from the exhaust end of the outer cylindroidal member such that a paraboloidal suspension is formed within a reactor.

Abstract: Replaceable heat insulation is provided for water-cooled pipes comprising structural supports and skid rails in slab reheating furnaces and like high-temperature metallurgical furnaces wherein the insulation is comprised of two mating sections of convenient length arranged to surround or, in the case of skid rails, largely surround the water-cooled pipes, the sections having metal fastening at their confronting edges brought into interfitting relation by sliding one section along the pipe relative to the other with provision for tightening the sections against the surface of the pipe and bringing portions of the interfitting metal fastenings into heat conducting contact with the water-cooled pipe. When each pair of sections has been fitted about the pipe and interlocked, but before being tightened about the pipe, each pair after the first is slid as a unit along the pipe into abutting position against the exposed end of the preceding pair and when so positioned being then firmly tightened about the pipe.

Abstract: A heat-reflecting panel having a neutral-color outer appearance has a transparent film support, such as a glass pane, an interference film having a refractive index >2 disposed on the support, a heat reflecting gold film of a thickness of 70-105 A disposed on the side of the interference film remote from the support, and neutralization film formed from chromium, iron, nickel, titanium or alloys thereof, or an alloy of chromium, aluminium and iron, the neutralization film disposed on the side of the gold film remote from the interference film.

Abstract: A metal melting furnace is provided having an enclosing roof that has a refractory brim portion affixed to and carried by the side walls, and has a refractory crown portion that is adapted to be removably positioned to close-off and open a central charging opening defined and encompassed by the brim portion. The crown portion by-passes electrodes in its "down" position and is to be raised and lowered and swung into and out of a clearing position with respect to the charging opening. Exhaust fume from a side-positioned smoke hole of the furnace is directed either into and positively drawn through a side-positioned-preheating scrap container or through an exhaust chest for subsequent environmental treatment before discharge into the atmosphere.

Abstract: An explosion venting device for metallurgical furnace enclosures consists of a plurality of panels adapted for restrictive movement relative to the roof and sidewalls of the enclosure and cover openings therein. The panels absorb the shock blast of an explosion occurring within the housing by lifting outwardly from the housing walls. Being restrictively movably mounted, the blast force may be vented in any desired direction. When the explosive force ceases, the panels will return to their rest position against the housing.

Abstract: A device for adjusting two butt ends of rails to be connected by welding comprises a rigid structure which is formed by two support plates. The support plates are aligned and interconnected by a concave part and which is able to be disposed horizontally so that the two support plates are pressed one against one vertical side of the head of one of the rails and the other against the corresponding vertical side of the head of the other rail. The concave part provides a region for access around the butt ends. Each support plate is provided with a retaining clamp which is provided with a jaw able to bear against the opposite vertical side of the head of the rail. The device can be applied to the welding of rails on a track or on a fixed installation.

Abstract: An improved information display assembly with a cantilevered arm and a detachable means for displaying indicia at the free end of the arm is disclosed. The free end of the arm has a horizontal member extending therefrom at a right angle. There is a transverse groove on the upper surface of the arm. This groove is on the free end of the arm and is parallel with the horizontal member. The detachable display means mounts onto this horizontal member and arm. This display means has a planar member with a front face upon which indicia is displayed and a rear face from which extend two parallel arms with a flange extending from the free end of the upper arm. When the display means is mounted on the cantilevered arm, the parallel arms are contiguous with the upper and lower surfaces of the cantilevered arm and horizontal member and the flange engages the transverse groove.

Abstract: A preparation and method for the treatment of burn victims. The preparation comprises an aqueous mixture of a perborate stabilized aqueous solution of chlorine oxides and glycerine. The preparation is applied to the burn area as a wet compress and the area exposed to ambient air between such applications.

Abstract: This invention relates to a sieving roller conveyor for transporting green pellets and for sieving off fines. The conveyor comprises a series of horizontally disposed rollers which are alternately spaced to provide a cleaning clearance and a sieving clearance. The rollers extend transversely to the direction in which pellets are to be conveyed and are rotatably mounted in a frame and provided with drive mechanism for the rotation of the rollers in the direction in which the pellets are to be conveyed.

Abstract: A mine roof support plate bolt formed from a concrete reinforcing rod has a head and flange at one end and a groove at the other end thereof, the groove forming opposed cutting edges at that end of the rod, and a counterclockwise, arcuate, helical channel in the section of the rod adjacent said other end, the counterclockwise, helical channel communicating with the groove, such that good mixing of resin adapted to secure the bolt in a bore hole is effected, while the cutting edges enable lengthening of the bore hole in instances where the rod would otherwise not pull the support plate flush with the roof structure.

Abstract: An improved apparatus for aligning and setting the gap between two rail ends comprises a rigid housing overlapping the two rails and providing an access area around the two rail ends. A first pair of presses and a second pair of presses are mounted in line on the frame and arranged so that the first pair of presses is situated between the second pair of presses. Each combination of a first press and a second press serves to grip one of the two rails to be joined. A pair of vertically mounted jacks are operatively secured to the second pair of presses to provide vertical movement of the second pair of presses independent of the rigid housing. Vertically adjustable support stops engage the tops of the rails and together with the vertically adjustable second presses effect vertical adjustment of the rails. The improved apparatus can be mounted singly or in pairs on a gantry and can include gap setting apparatus and weld dressing apparatus.

Abstract: A magazine rack which may be disassembled into only four component parts to facilitate transportation and storage. The magazine rack may be assembled without separate fastening means, and due to its unique configuration no separate base or floor section is required.
