Title: Improvements in or relating to the construction of walls for glass melting furnaces
IPC: C03B5/43
Filed: 1938-10-12
Abstract: 520,189. Glass furnace hearths and walls. JACKSON, L. MELLERSH-. (Hartford - Empire Co.). Oct. 12, 1938, No. 29584. Drawings to Specification. [Class 51 (ii)] The hearth of a glass furnace is formed of granular material which will react with molten glass to form an impervious layer while leaving the subjacent material still granular to act as a heat-insulator. The granular material should contain from 30 to 95 per cent. of alumina, and may be made by baking a. plastic mixture of bauxite, monohydrate of alumina, clay and felspar containing 74 per cent. of alumina and 21 per cent. of silica, the remainder consisting of oxides of iron, titanium, calcium, magnesium and sodium, and subsequently breaking the . baked material down into grains of the desired size. Preferably the grain size of the layer increases from the glass contacting surface outwards, and the initial formation of the impervious surface layer may be facilitated by spreading a layer of glass on the granular material. The marginal edges of the layer which contact with the side walls of the furnace, may consist of grains of the electro-cast silica-alumina material described in Specification 265,847, [Class 22], either alone or mixed with alumina in the proportions 85 per cent. electro-cast grains and 15 per cent. alumina the former being coarsely and the latter finely ground, or this mixture may be used for the whole upper layer. The specific gravity of the refractory should be greater than that of molten glass. Specifications 226,801 and 303,574, [both in Class 51 (ii)], also are referred to.

Title: Improvements relating to the manufacture of anhydrous silicon, boron and metal halides
IPC: C01F7/56
Filed: 1953-10-29
Abstract: Chlorides, bromides and iodides volatile at temperatures below 1200 DEG  C. of silicon and boron and of metals other than the alkali metals, alkaline earth metals and rare earth metals, specifically those of Ti, Si, Ge, Zr, Hf, Th, Al, B, Nb, Ta, Fe, Sn, Mo, W, As, Sb, Ga, are prepared by heating to at least 500 DEG  C. an anhydrous mixture of an alkali metal double fluoride of the desired metal and the chloride, bromide or iodide of magnesium, calcium or lithium and withdrawing the desired vaporized chloride, bromide or iodide leaving as residue the fluoride of magnesium, calcium or lithium, and that of the alkali metal employed.  The starting materials may be individually or collectively rendered anhydrous prior to reaction, suitably in situ, for example by heating to 350 DEG  C., until the pressure can be maintained under vacuum pumping, as low as 200 microns.  Stoichiometric proportions of pure recrystallized reactants are preferred and the reaction residue may be recycled to produce the double fluoride employed or converted to the bromide, chloride or iodide employed.  The reaction mixture is preferably not fused and the reactants are preferably mixed and charged as briquettes.  If the reaction mixture is fused, the reaction may be carried out in a diluent bath of alkali metal halides or the alkali metal double fluoride may be charged incrementally to a fused bath of the molten chloride, bromdie or iodide of magnesium, calcium or lithium. The reaction chamber should be under vacuum or swept with an inert gas to entrain the evolved vapours and conduct them to a cooling zone.  The reaction residue, for example magnesium and potassium fluoride, may be employed to produce the alkali-metal double fluoride of the desired metal by aqueous phase reaction, for example, by reaction with aluminium sulphate.  Lithium and calcium fluoride residues are suited for a fusion process of alkali metal double fluoride production or they may be converted to chlorides and recycled.
