Abstract: 901,811. Toys; models. KELLOGG CO., M. W. Oct. 29, 1958 [Feb. 25, 1958], No. 34644/48. Classes 132 (3) and 146 (2). [Also in Group XXV] A jig 30 for assembling elongated model structural members comprises a flat plate section 31 and a stepped secondary section 32 which includes a part 36 lying in a plane normal to the plane of the main section 31. Parts 33, 34 and 35 of the main section 31 and the part 36 of the secondary section 32 are each provided with a pair of upstanding prongs 37 and a saucershaped clamping cam member 38; the latter is eccentrically mounted on the end of a pin 40 extending through the part and having a wing piece (not shown) for rotating the pin and so the cam member. A protuberance 42 on each part serves to limit the rotation of the respective cam member 38 to a position in which the flange of the model structural member, e.g. an I-beam column 12 (Fig. 2), may be easily inserted in position, the cam member 38 being then rotated to engage the flange of the I-beam so as to clamp the flange against the face of the part and the associated prongs 37, the latter being bent out of the plane of the part through more than 90 degrees. As shown, the jig 30 is positioned at the upper end of the I-beam 12 which is clamped against the part 36 of the secondary section 32, and the main section 31 has clamped thereto horizontal I-beams 13 and 14. The I-beam 12 is retained vertically in position by having the web at the lower end thereof inserted in a slotted head 46 of a pin 45 which is entered into a mounting board 48. In a modification, Fig. 4 (not shown), the secondary section 32 is adjustably secured to the main section 31 by means of a screw-and-slot connection, the main section 31 being provided with a plurality of spaced indentations adapted to receive a protuberance on the secondary section 32 to facilitate accurate positioning of the latter.

Abstract: 903,897. Reducing metallic oxides. KELLOGG CO., M. W. Sept. 22, 1960 [Oct. 5,1959], No. 32568/60. Classes 72 and 82 (1). A method of reducing granular metallic oxides comprises introducing into a molten metal bath a reducing agent and injecting the granular metallic oxide into the molten metal whereby the oxide is reduced and the molten metal formed is removed. As shown, applied to the reduction of oxidic iron ore, a bath 12 of pig iron is formed and oxide ore mixed with a liquid, solid, or gaseous, carbonaceous reducing agent and slag forming materials is introduced below the metal surface through a lance 11. Air from a regenerator 15 is fed to the same end of the furnace, part of this air being used to burn oil from a burner 18 and the remainder to burn carbon monoxide produced by the reaction between the reducing agent and the ore. When the air is changed over to the other end of the furnace, the ore and other additions are injected through a lance 26. Metal is removed from the furnace through an opening 23 and slag through an opening 24. When the reducing agent does not produce large quantities of gas, e.g. coke, it may be added at the centre of the furnace only. Chromium and manganese oxides may be reduced to metal by the process.
