Title: Process for the oxidation of aromatic hydrocarbons
IPC: C07C51/265
Filed: 1956-09-27
Abstract: Aromatic carboxylic acids or intermediate oxidation products thereof are prepared by the oxidation in the liquid phase of aromatic compounds having one or more aliphatic side-chains with molecular oxygen in the presence of a metal oxidation catalyst and in a reaction medium comprising an aliphatic monocarboxylic acid having 2-8 carbon atoms, wherein the oxidation of substantial quantities of the reaction medium is prevented by maintaining the oxygen content of the exit gas from the reaction at less than 15% by volume.

Bases for posts; erecting posts. - A steel lattice or other mast is secured by a pivot to a base and its lower end projects below the base into an excavation in the ground so that it is held against tilting by the resistance of the undisturbed soil. In the form shown in Fig. 1 the pivot 3 is carried on a frame formed of inclined members 6, 7 and horizontal members 4 bedded in concrete blocks 5. The end 1 of the mast extends below the base as shown and is bedded in a concrete block 2.

Title: Treatment of germanium-containing materials
IPC: C22B41/00
Filed: 1956-10-02
Abstract: The germanium content of a material comprising oxidic germanium, arsenic, and zinc is increased by treating the material with an ammoniacal solution which, at the end of the process, has a pH value above 8, the arsenic and zinc contents being selectively leached from the material.  The solution used may contain sufficient ammonia to give a pH value between 9 and 11.5 and may also contain 50-200 grs. per litre of ammonium sulphate as a buffering agent.  The solution and the material may be agitated and the pH value of the solution varies only slightly during the process, e.g. an initial pH value of 10.4 may result in a final pH value of 9.8.  The material may be obtained by dissolving an impure germanium oxide in sulphuric acid and adding ammonia until the pH values reach 9.4 when germanium, arsenic, and zinc will be precipitated, the precipitate being filtered and washed before being subjected to the leaching treatment.ALSO:The germanium content of a material comprising oxidic germanium, arsenic and zinc is increased by treating the material with an ammoniacal solution which, at the end of the process, has a pH value above 8, the arsenic and zinc contents being selectively leached from the material.
