Title: Improvements in or relating to the stabilisation of oils
IPC: C11B5/00
Filed: 1952-11-25
Abstract: Fatty or mineral oils damaged by autoxidation are refined by "blocking" the peroxide compounds formed, to prevent further action on the oil to produce rancidity, by reacting the oil with an alcoholate of a di- or polyvalent metal to form a metal compound of the initial oxidation impurity, and then separating solid or liquid reaction products therefrom.  The oils may be in an emulsified form and may comprise edible oils, lubricating oils, spindle oils and spinning oils.  The oils specified comprise colza oil, linseed oil, a spinning oil prepared from glycerine and oleic acid and a lubricating oil of mineral oil basis.  The alcoholates specified comprise alcoholates of iron, aluminium and titanium, particularly butylates and hexanolates of these metals, and aluminium ethylate.  The alcoholates may be used in a stabilized form by mixing or reacting them with tautomeric reacting compounds, e.g. b -ketocarboxylic acid esters such as acetoacetic ester, malonic acid esters or b -diketones such as formylacetone and formylacetophenone.  Such stabilized alcoholates are resistant to water.  The alcoholates, stabilized or not, and if desired dissolved in organic solvents, may be added to the oil in the cold, or the oil may be heated.  The solid reaction products may be removed by filtration or centrifugation, and alcohol formed may be removed by distillation.  After the reaction, the oil may be treated with water to precipitate the impurities.

Title: A method of kilning ceramic wares in a tunnel kiln and a tunnel kiln for performing the method
IPC: F27B9/26
Filed: 1962-08-03
Abstract: 1,015,213. Tunnel kilns. KELLER OFENBAU G.m.b.H. Aug. 3, 1962 [April 19, 1962], No. 29870/62. Heading F4B. Ceramic ware is fired in a tunnel kiln heated by combustion in a space between the cars and the roof and walls of the kiln, the flow of air in counter - current through the kiln being adjusted by setting the flow section of channels extending longitudinally and transversely of the cars, and, except for air introduced with the fuel, no air or gases are withdrawn from or introduced into the kiln between the ware discharge end and the ware entry end. The longitudinal channels 12 and transverse channels on the kiln cars are formed by channel section bricks 9<SP>1</SP>, 911 arranged on the cars, Fig. 4, and flow restricting elements may be placed in the channels. Skirts 13 on the cars dip into sand troughs at the sides of the kiln. The kiln has fuel ports 6<SP>1</SP> in the firing zone, Fig. 1, and outlet flues 7 at the ware entry end communicating with ports at the level of the car platforms. The ends of the cars have overlapping strips 16 and an asbestos gasket 18 co-operating with a flange 17, Fig. 6, and the support structure 22 for tiles to be fired are arranged to form longitudinal channels and transverse firing channels 21, Fig. 11. The amount of air entering the kiln at the ware discharge end is such that the product of its mass and mean specific heat is equal to the product of the mass and mean specific heat of the ware plus an allowance for the cars and furniture. Since no additional air or gases are fed to the kiln or removed from it before the gases reach the flues 7, this enables the greatest possible use to be made of the heat withdrawn from the ware in the cooling zone.

Filed: 1955-10-27
Abstract: 808,766. Welding by pressure; soldering. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., LANGRIDGE, A., HUNTER, D. J., and GRIMWOOD, H. W. Sept. 25, 1956 [Oct. 27, 1955], No. 30742/55. Class 83 (4). [Also in Group XXXVI] A method of making an hermetically sealed container for a semi-conductor device capacitor or resistor comprises sealing together two metal members on each of which is a metal-coated annular band, at least one of the bands being formed on an axially tapered surface. The members are axially aligned and pressed together, at a temperature at which the bands will adhere, to deform at least one member over part of its tinned surface so that the bands are firmly pressed together and caused to slide over each other. When indium is used for the bands, adhesion takes place at room temperature but the Provisional Specification refers to the use of a low-temperature solder and to performing the pressing operation in an oven. The tapered surface may be formed on the interior surface of a cavity in a rigid metal member, in which case the other member is a deformable tube, or both members may be deformable tubes tapered in opposite directions. In the embodiment one of the members is a threaded brass plug 1 the tapered surface 10 of which is coated with indium. A germanium body 5 is soldered in a cavity in the head of the plug and a rod 7 soldered to its upper surface by a layer 6 of indium to form a sub-assembly. A second subassembly is formed by a copper tube 3 of uniform diameter through one end of which a metal tube 7 carrying a brass collar 13 is sealed by a glass bead 8. The lower inner surface of the tube is tinned. The sub assemblies are then pressed together to force the tube over the tapered surface of the plug, as shown. During this process the tube is deformed and the indium surfaces are scraped clear and adhere to each other. A copper cap 15 to which a braided connector 16 is riveted is then forced over the tape or collar to form an intimate electrical connection between its tinned inner surface and the tinned taper of the collar.
