Title: Production of high purity refractory flour
IPC: B22C5/06
Filed: 1963-06-27
Abstract: A refractory flour, essentially free of iron bearing material, is produced by subjecting a refractory material, e.g. silica, alumina, zircon, zirconia, calcia, periclase, periclase-silica, chrome and chrome periclase, to a preliminary size reduction, isolating from the reduced product an intermediate fraction substantially all of which passes a 16 mesh and is retained by a 100 mesh Tyler screen, removing substantially all the iron from this intermediate fraction, and then submitting the fraction to a further size reduction to give the desired refractory flour all of which is - 150 Tyler mesh, and which is substantially free of iron.  The second size reduction must clearly be carried out so as not to introduce any iron into the refractory, and is preferably performed in a ceramic mill.  The oversize particles from the screening step are returned to the crushing step, but the undersize particles are discarded.  The refractory material is preferably bauxite which is calcined to remove all free water and substantially all combined water prior to the first size reduction.  The iron content of the refractory flour produced is preferably less than 0.001% by weight and it is used as an investment moulding material.

Title: Improvements in and relating to the gelling of an alumina hydrosol
IPC: C01F7/02
Filed: 1963-06-28
Abstract: An alumina hydrogel is obtained from an alumina hydrosol of formula xAl(OH)3.AlX3, where x is 4-6 (which is preferably mixed with water to a 15-35% concentration of alumina) by adding a mixture of urea and hexamethylene-tetramine having an ammonia concentration of 0.75-2.25 equ. per equ. of the anion (X) present, and allowing to stand or heating to evolve ammonia, which neutralizes the sol and causes it to gel.  The gel may be calcined to give alumina.  The anion (X) may be chloride, bromide, sulphate or alcoholate. 10-30% solutions of urea and hexamethylene tetramine are used, in the ratio 0.3 : 1 to 9 : 1. Before gelling occurs, the mixture may be dispersed as droplets in an oil bath at 120-210 DEG  F., and the resulting hydrogel spheroids are aged in hot oil and then in aqueous ammonia or alkylamine; dried and calcined. Forming and aging in oil may be effected at 210-500 DEG  F. under superatmospheric pressure.  An initial AlCl3 containing sol may be formed by (a) digesting excess Al metal with aqueous 12% HCl, (b) eletrolysing AlCl3 solution, or (c) heating Al metal with AlCl3 solution at 175-220 DEG  C.; the Al : Cl ratio is then adjusted to 1.2 : 1.

Class 6(iii) A beet-harvester of the type having a pair of guide rails 7 preceding the lifting share 6 is characterized in that the rails are connected to the steering mechanism of the land wheels 4 of the machine so that their movements are imparted to the share. The machine comprises a main. frame 1 towed by a tractor through a clevis 27 and supported on wheels 4 which rotate on stub axles 23 pivoted on a normally-stationary axle 3. The share 6 is fixed to the main frame 1 and is followed by spinners (not shown). The rails 7 are pivoted at their upper ends so as to be rotatable and transversely-slidable on the axle 3. The yoke 10 is pivoted to a bifurcated lever 11, pivoted at 13 to the mainframe 1 and joined by a pin-and-slot 14 to a track-rod 12 interconnecting two forks 25 mounted on the stub axles 23. Lateral movements of the rails 7 are thus transmitted to the wheels. A leaf spring 17 maintains the guide-rails 7 in ground engagement. The axle 3 is rotatable to raise the tools and rails from the ground through ratchet clutches in the wheel hubs. When this occurs, the rail and the lever 11 automatically return to a central position.
