Title: Method and apparatus for refining substances containing oils and fat
IPC: C11B1/06
Filed: 1937-11-08
Abstract: <PICT:0494209/III/1> Liquid or pulpy masses containing fats and oils are pressed through constricted passages with air, steam, or liquid or gaseous solvents, to extract the fats or oils.  The pulpy mass is fed into the container 2 heated by the steam pipes 18.  The container 2 is incompletely filled and a pressure tube 5 projects into the free space.  Air or gas under the pressure from the tube 5 forces the pulpy mass up the tube 4, along the conduit 7 into a device 12 also heated by the steam pipes 18.  Additional gas or gas admixed with chemicals is supplied to the mass via the nozzle valve 6. The pulpy mass mixed with gas, steam, solvents or chemical reagents, is forced into the device 12 which consists of a cylindrical casing 12 fitted with a stationary core having annular grooves 8 which communicate by flattened portions 15 of the ribs 10 between the grooves.  The attenuation undergone by the mass in passing from one groove to another by way of the constricted passages 15, on its way through the casing 12 to the delivery tube, causes maximum separation of the oils and fats.

Title: Improvements in or relating to the surface treatment of metals of or containing aluminium
IPC: C23C22/66
Filed: 1945-11-15
Abstract: In a method of treating the surface of aluminium or aluminium alloys, the surface is immersed in a hot aqueous solution prepared by dissolving in water 4 to 8 ozs. per gallon of an alkali metal hydroxide and at least 6 ozs. per gallon of tin chloride until it is uniformly covered, removing the surface, washing it and rinsing it in a bath of concentrated nitric and sulphuric acids until the coloration is removed and finally washing it.  The amount of alkali may be adjusted to give a delay of 2 to 3 seconds before evolution of gas occurs at a temperature above 60 DEG  C., preferably 95-90 DEG C.  The alkali bath may also contain copper and ferric chlorides, the latter particularly when the alloy contains magnesium and the quantity may vary as the magnesium content of the alloy.  The acid bath may also contain hydrochloric or chromic acid and copper and zinc ions, these metallic ions being introduced by the addition of 2 to 3 ozs. per gallon of brass.  A thin film of tin is produced on the surface and other metals may be deposited electrolytically thereon either with or without an initial coating of zinc.  The tin coating may also be protected by a coating of paint or lacquer.

An hydraulic press for straightening, testing or other operations on castings or other bodies comprises a rectangular frame having lower and upper horizontal beams 1, 2 pivotally interconnected to a pair of vertical pillars 3, 4, a base 10 through which the lower beam extends and on which is a movable horizontal table 11, at least one hydraulic pressure unit 16 movable horizontally on the upper beam, and at least one hydraulic pressure unit 22 vertically movable on one or each of the pillars. Each beam consists of a pair of members separated by distance pieces 5 and connected by pivots 7, 8 to the pillars 3, 4 which also consist of pairs of members separated by integral or separate distance pieces 6. The lower ends of the pillars may also be connected to the lower beam by bolts 9 which serve to limit the angular movement of the beams. The lower beam extends through, and is secured to, the base 10 which supports the table 11 movable relative to the base by a rack-and-pinion mechanism 12 driven by an electric motor or other source; the table is supported on the base by spring- loaded rollers, the springs being compressed when the press is in operation. The upper beam carries at least one pressure unit consisting of a carrier 13 supported by rollers 14 which bear on tracks on the upper edges of the members of the beam and are driven by an electric motor 19. The carrier supports a piston 15 and cylinder 16 which has a head 18 or pads engaging the under surface of the members and is supplied with fluid pressure from a pump 21 and tank 20.
