Filed: 1968-04-30
Abstract: 1,205,885. Zinc oxide articles. McDONNELL DOUGLAS CORP. 30 April, 1968, No. 20530/68. Heading C1A. [Also in Division H1] ZnO is calcined at temperatures between 600-1800‹ C., mixed with untreated ZnO and then is compacted at 2000-10,000 p.s.i. to the desired shape and then sintered at a temperature not less than 600‹ C. to give a strong sintered ceramic-like zinc oxide article having desirable electrical properties. The mixture suitably contains between 50-90% wt. of said calcined oxide. The porosity of the product may be varied by adjusting the oxide ratio in the mixture, compacting pressure, sintering temperatures or by the inclusion of burn-out materials and is preferably maintained in the region of 15-60% porosity. The zinc oxide may he electroformed to convert it to zinc for use as an active electrode in a silver-zinc battery.

Title: Production of curvilinear tiling elements
IPC: E04F15/08
Filed: 1926-08-27
Abstract: 268,214. Compagnie GÚnÚrale de la CÚramique du BÔtiment. April 9, 1926, [Convention date]. Facing tiles; flooring tiles.-To form mosaic and like tiles with curved peripheries, a surface is divided up into regular polygons, and circles are struck from each angular point of the polygons with a radius equal to the length of the side. Many shapes of tiles are obtained by tracing out closed figures by following along the curves thus produced. For example, the whole of the shapes of tiles illustrated in Figs. 4 - - 12 can be obtained by dividing up the surface into equilateral triangles as show in Fig. 2. Since the arcs are all of equal radii, the convex portion of any tile will inter-fit exactly with the concave portion of any other tile. In building up patterns, certain of the tiles may be grouped to form patterns while others of different shade are utilized to fill in and form a background. Specification 526/84 is referred to.

Title: Process for the production of ferromanganese from high-grade manganese-bearing materials
IPC: C22C1/02
Filed: 1956-07-09
Abstract: High-carbon ferro-manganese is produced from ore containing oxides of manganese, iron, calcium and silicon the ore being passed to the surface of a molten slag bath in an electric furnace in the form of a hot, calcined substantially constant composition charge with a controlled amount of solid carbonaceous reducing agent and being smelted at a temperature in the range 1300 DEG C. to 1500 DEG C.  The charge is so composed that the slag contains a small amount of calcium carbide and contains silica and basic oxides (excluding manganese oxides) in the ratio of 1 molecule of silica to 1.7-2.2 molecules of basic oxide.  The arc tips of the electrodes are maintained from about 1/2 inch above the upper surface of the slag bath to about 3 inches below it.  The depth of slag is controlled to give a substantially constant resistance and the charge is introduced at such a rate and in such a direction as to avoid submergance of the arcing tips beneath the raw charge material.  The calcium carbide may be added as such to the slag or formed therein by reaction of lime with a sufficient excess of carbonaceous material.  Iron may be added to the charge as scrap metal or as iron oxide.  Specification 762,469 is referred to.

Title: Process for the manufacture of tungsten carbides without free carbon for use as tools and implements of all kinds
IPC: C22C1/10
Filed: 1921-08-15
Abstract: In the production of tools or implements from tungsten carbides (WC or W2C), for instance by the processes described in Specifications 157,747 and 157,750, it is desirable to heat to a temperature above the melting-point in order to vaporize impurities such as iron, extra carbon is liable to be taken up, which separates as free carbon on solidification.  This free carbon is removed by adding a quantity of molybdenum, as carbide, metal, or oxide.  The carbon is volatilized with the molyhdenum or oxidized by the oxygen of the molybdenum oxide without leaving any residual molybdeum.  The carbide can thus be heated to much above the melting point so as to obtain a completely liquid mass from which sharp castings can be obtained, for instance by the process described in Specification 157,756, [Class 83 (iv), Metals, Working].
