Abstract: Metal oxide particles, such as particulated iron ore, are fed to the surface of a molten metal melt containing carbon which reduces the oxides and thus adds the metal to the melt. The latter''s carbon content, necessary for the reduction, is maintained by feeding carbonaceous material to its surface, the carbon with time, dissolving in the melt. The latter is heated by an electric induction coil designed to induce electric currents in the melt with a flux field pattern causing a bulge to form upwardly in the melt in the shape of a closed loop having inner and outer descending slopes of oppositely flowing molten metal, this loop of bulging metal being largely above the level of slag formed from gangue included by the oxides, and presenting metal surfaces which are free from slag or naked. The particulated oxides are fed to the inner slope so that metal is added to the melt while the slag collects in what is in effect a valley or basin formed in the melt within the upwardly bulging loop of metal. The melt is contained in an electric induction furnace hearth having an upstanding side wall surrounding the bulging loop at a distance forming an annular or peripheral valley of molten metal which free from slag because the oxides are not fed to the outer slope of the loop. The carbonaceous material required to maintain the carbon content of the melt, is fed to this outer slope and collects in this peripheral valley on naked metal free from slag, permitting the carbon to dissolve into the melt without interference by a slag barrier. A special induction furnace is provided wherein, among other features, the necessary induction coil is designed so that at one localized portion of the upwardly bulging loop of melt, the height or upward elevation of the bulge is lowered, the furnace having a tap hole in its side wall at this location for permitting the removal of slag collected in the basin or inner valley as well as the metal obtained by reduction of the oxides.

Abstract: In the hydrostatic extrusion of tubes using a pressure chamber and a mandrel, in order to center the mandrel the pressure chamber is divided into two parts by a piston-like billet holder, through which the mandrel passes. The billet holder includes a first portion with an opening on the mandrel and a second portion fitting within the pressure chamber. The first portion is radially slidable with respect to the second portion.

Abstract: Apparatus for measuring the amount of wood pulp processed by a timber grinding machine, including a motor driven log grinder and log feeder, and a counter for measuring the energy output of the grinder and feeder motors as an indication of the quantity of wood processed. A blocking circuit coupled to the motors disables the counter when the speed of the motors increases rapidly due to the emptying of the feeding mechanism.

Abstract: In order to prevent unwanted tripping of a direct current apparatus, such as a relay, when it is switched in to a direct current network or in the case of an earth fault, a safety circuit is connected in parallel with the apparatus which includes a capacitor which is so large in relation to the other capacitances in the switched-in circuit that the voltage which is taken up by the capacitor in the switching operation is less than the tripping value of the apparatus. A diode is provided in a connection of the safety circuit to the apparatus to prevent the fall of the relay from being caused by the capacitor.

Abstract: A railroad bottom-dumping goldola car has open-topped side and end walls and an open bottom closed by one or more transversely downwardly swinging door or doors, and trucks which run on railroad track rails which are interrupted to form a space over a dumping location below the rails'' level. The car may itself have only one truck at one end, its other end sharing the truck of an adjacent corresponding car of a train of the cars. The car has longitudinally extending rails along its sides on the upper edge of the frame which run on supported horizontal series of rollers supporting the car while it traverses the space between the interrupted rails, and the body''s swinging door or doors are swung open and shut on hinges, by an operating cam follower wheel journaled to the door in each case and running on a downwardly and upwardly contoured cam rail which spans the space formed by the interrupted rails, the cam rail defining a constant radius equal to the spacing of the hinge axis and the cam follower wheel. This gondola car features a rectangular frame defined by longitudinal sides extending along the car''s side for its length and transverse ends supported by the trucks, the frame defining an opening providing complete dumping clearance when the door or doors are opened. The frame''s ends are adapted for coupling to the ends of other frames of corresponding gondola cars to form a train via the common trucks, or in some instances, via the frames themselves, in all instances being made strong enough to carry the forces of jolts and tensions of train operations, preventing these forces from being transmitted to the car''s walls surrounding the open bottom. A number of the cars may be made up into a train of the articulated type, the adjacent ends of each two adjacent cars sharing the common trucks, thus providing for a greater length of open bottom and its door or doors than if each had its own two trucks.

Abstract: In a nuclear reactor with vertically arranged fuel assemblies positioned on supporting members and with control rods displaceably arranged in guide tubes between the fuel rods inside the fuel assemblies, the supporting plate is provided with a transverse end piece with throttling means for the liquid flow which passes from below up through the supporting member and past the fuel rods in the fuel assembly. The inlets for the guide tubes for the control rods are located below the end piece and the throttling means. In this way a higher pressure prevails at the inlet to the guide tubes than above the end piece, so that a stronger flow of coolant is produced through guide tubes than through the fuel assembly.
