A method of producing fused abrasive grain, comprises forming a molten composition of the abrasive material and pouring while, close to its freezing temperature on to a mass of solidified lumps of a similar composition of size “ to 24 inches, the ratio of the mass of molten material to that of the lumps being between 0À35 and 2À0 and allowing the molten composition to freeze while mixed with the lumps. The abrasive may be alpha-alumina, a mixture of alpha-alumina and zirconia, zircon, zirconia, or bauxite, and may be mixed with other additives. The solidified mass may be comminuted by impact crushing. An abrasive grain obtained by the method comprises a mixture of alpha-alumina and zirconia, the amount of zirconia being 10-60% by weight, the grain having a numerical average crystal size of less than 50 microns.

Abstract: 1,234,009. Terephthalic acid. E. I. DU PONT DE NEMOURS & CO. 3 Sept., 1969 [3 Sept., 1968], No. 43649/69. Heading C2C. Crude terephthalic acid, obtained by the liquid phase oxidation of an aromatic hydrocarbon starting material with molecular oxygen in the presence of a heavy metal catalyst, is washed at a temperature of over 250 C. with an aromatic single ring hydrocarbon, e.g. benzene, toluene, a xylene, to remove partiallyoxidized impurities therefrom. Preferably the aromatic hydrocarbon starting material is p - xylene and the oxidation is carried out at 160-220 C. at pressures of 100-400 p.s.i.g. in the presence of a cobalt or manganese naphthenate, linoleate, phthalate or 2-ethylhexoate. The single ring hydrocarbon is preferably pxylene and the washing is carried out at 290- 300 C. at pressures of 300-500 p.s.i.g.; the p-xylene wash liquor may be recycled for oxidation.

Abstract: 1,239,209. 209. Electron capture detectors. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov.26, 1968 [Nov.28, 1967], No.54140/67. Heading G1N. [Also in Division G4] An electron capture detector cell 30 is energized from a pulse generator 3, the frequency of which is automatically adjusted by a feedback circuit to keep the average current through the cell constant whereby a linear relationship between the concentration of an electron capture material and the frequency of the pulse generator is obtained. A frequency meter 9 indicates concentration and a pulse counter may be included to determine the total amount of electron capture material passed through the detector. The detector cell current is measured by a high input impedance electro-meter 28 connected to a high resistance voltage divider chain 23, 24, 26, the wiper 25 being adjusted to vary the relationship according to which the frequency is adjusted in dependence on the detector current. The output of the electro-meter is connected to an indicator or recorder 10.
