Filed: 1938-12-09
Abstract: 522,586. Ceramic materials to be sealed into glass. GENERAL ELECTRIC CO., Ltd., and LAIT, J. R. Dec. 9, 1938. No. 36013. [Class 22] [Also in Group XXXVI] Ceramic materials to be sealed. into glass are formed by mixing steatite with a refractory insulating material which alters its rate of expansion with heat without diminishing its electrical resistance. Preferably the rate of expansion with heat of the mixture is slightly greater than that of the glass into which it is to be sealed. For increasing the rate of expansion, magnesia may be used. Zirconia up to 10 per cent. increases the rate of expansion and in larger quantities diminishes it. For lowering the rate of expansion, zirconium silicate may be used. The mixture of the finely powdered material, which should contain not less than 50 per cent. of steatite is, with or without a binder, fired at 1350‹C. The material is afterwards coated with glass of the composition of that to which it is to be sealed. Specifications 260,298 and 282,403 [both in Class 22], are referred to.

Title: Improvements in or relating to the production of aromatic acids
IPC: C07C51/265
Filed: 1958-11-11
Abstract: In a process for the oxidation with molecular oxygen, of an aliphatic-substituted aromatic compound or a fused-ring aromatic compound, dissolved in an inert solvent and in the presence of a heavy metal oxidation-catalyst, advantageously promoted by bromine or bromide ions, the oxidation-product is submitted to distillation to separate the inert solvent and, if desired, part of the aromatic acid product, and the distillation-bottoms are extracted with water or a lower aliphatic or naphthenic monocarboxylic acid in order to separate tar-like by-products from the catalyst so that the latter may be reused in the oxidation reaction.  The extraction is preferably carried out with between 3 and 50 volumes of solvent per volume of bottoms, and at a temperature between 50 DEG C. and 150 DEG C.  In some cases, the catalyst extract may be used in the oxidation; in other cases the catalyst is separated from the extract so that the catalyst alone may be recycled.  In an example, a reaction-mixture from the air-oxidation of mixed petroleum xylenes in acetic acid and in the presence of a bromine-promoted manganese and cobalt acetate catalyst, is cooled and filtered, whereby a filter-cake comprising ortho-, iso-, and terephthalic acids is obtained.  The filtrate is distilled at atmospheric pressure to remove acetic acid and water-of-oxidation, leaving a solid residue which contains catalyst, benzoic acid, toluic acids and phthalic acids.  This residue is distilled under an absolute pressure of 40 mm. to remove benzoic acid and some of the orthophthalic acid (as anhydride).  The distillation-bottoms is divided into two portions.  One portion is pulverized and extracted with hot water; and the other portion is pulverized and extracted with hot acetic acid.  Both extracts are filtered and evaporated to dryness whereby two pale-coloured solids are obtained, which are found to contain over 90% of the catalyst in the distillation-bottoms but only minor proportions of tar-like oxidation by-products.  Both extracts are suitable for recycling to a subsequent oxidation step.  A list of aromatic compounds which may be oxidized according to the process of the invention is given in the Specification; also a list of catalysts, which includes nickel, chromium, vanadium, molybdenum, tungsten, tin, neodymium and cerium.

IPC: B64C25/50
Filed: 1955-12-22
Abstract: 813,912. Vehicle power steering. DOWTY EQUIPMENT Ltd. March 22, 1957 [Dec. 22, 1955; Jan. 5, 1956], Nos. 36830/55 and 460/56. Class 79(5) An aircraft nosewheel is steered from a manually-operated control member by a servo mechanism which includes means to vary the ratio of angular movement of the nosewheel to that of the control member so that the latter exercises a fine control on the wheel for small steering angles and a coarse control for wide steering angles. In the preferred embodiment, a rudder bar 50 is connected to the slider of a potentiometer 46 determining the potential at one end of a coil 72 while the nosewheel is connected to the slider of a potentiometer 42 determining the potential at the other end of the coil. The direction in which current flows through the coil 72 is determined by the direction of movement. of the rudder bar so that one of a pair of solenoid valves is energized to permit fluid to flow to a hydraulic cylinder which turns the nosewheel and the slider of potentiometer 42 until the potential difference across the coil 72 is again zero. When the throttle 87 is advanced for take-off, a . switch 81 closes a circuit to a coil 57 which displaces an armature 56 to substitute a potentiometer 44 of reduced length for the potentiometer 42, so that the same movement of the rudder bar produces a smaller movement of the nosewheel. In an alternative arrangement, the potentiometers 42 and 44 are replaced by a potentiometer having turns of non-uniform length or width to provide a steering control which becomes progressively coarser as the steering angle increases. Specification 625,764 [Group XXXVIII] is referred to.
