Title: Method and composition for treatment of soils
Inventor: GLENN JOHN HARLAN
IPC: F02B3/06
Filed: 1960-10-28
Abstract: Aqueous emulsions comprising either (a) a petroleum hydrocarbon oil and a C16-18 fatty acid and/or a rosin acid, said acid being at least partly saponified or (b) an emulsion of (a) and an aqueous solution of at least one linear hydrocarbon chain polymer having a molecular weight greater than 10,000 and containing one alkali metal or ammonium carboxylic acid salt group per 2-6 linear chain carbon atoms, are used to reduce the porosity of planted areas such as lawns or potato fields, e.g. by adding to the irrigation water. Rosin acids are defined as monocarboxylic acids of alkylated hydrophenanthrene nuclei.  Emulsions (a) are of water-in-oil type and (b) are of oil-in-water type.  Specified hydrocarbon oils are kerosene, diesel oil, lube stock and a refined oil of 40 DEG  API.  Specified acids are abietic acid, tall oil (comprising linoleic and oleic acids). Sodium polyacrylate is exemplified as the polymer and in Examples 12 and 13 a potato field and a lawn are treated with an emulsion comprising tall oil (3.95 gm.), caustic soda (0.43 gm.), diesel oil (39.97 gm.) and sodium polyacrylate (1.06 gm.).ALSO:A water-in-oil emulsion suitable for treating soil comprises a petroleum hydrocarbon and a C16-C18 fatty acid and/or a resin acid, said acid being at least partly saponified.  Rosin acids are defined as monocarboxylic acids of alkylated hydrophenanthrene nuclei.  Specified hydrocarbon oils are kerosene, Diesel oil, lube stock and a refined oil of 40 DEG A.P.I. or less.  Specified acids are oleic, abietic, linoleic acids, tall oil (acidified skimmings of waste black liquor, comprising linoleic and oleic acids) and a mixture comprising palmitic and linolenic acids in addition to the above acids.  Suitable alkalies for the saponification are sodium, potassium and ammonium hydroxides, sodium carbonate and sodium silicate, and may be added to a solution of the acid in the hydrocarbon to provide an emulsion which on 5-fold dilution with water has a pH of 9-10,5.  The resultant emulsion may be stabilized with an electrolyte, e.g. sodium chloride.  An oil-in-water emulsion may be prepared from said water-in-oil emulsion by adding the latter to an aqueous solution of a linear hydrocarbon chain polymer having a molecular weight greater than 10,000 and containing one alkali metal or ammonium carboxylic acid salt group per 2-6 linear chain carbon atoms, sodium polyacrylate being exemplified.  Details of the proportions of the various ingredients are given.ALSO:Examples 12 and 13 respectively describe the treatment of a potato field and a lawn with an aqueous emulsion comprising tall oil (3.95 gms.), caustic soda (0.43 gms.), diesel oil (39.97 gms.), and sodium polyaerylate (1.06 gms.).  The emulsion improves the water retentive properties of the soil.

[Also in Division C1] Nuclear fuel containing uranium and plutonium, e.g. oxides or carbides, or material derived therefrom, e.g. fluorides, is treated with chlorine monofluoride at below 700‹ C. so as to form solid PuF 4  and volatilize UF 6  which is condensed together with chlorine, and separated therefrom, the excess C1F being recycled for further reaction with the fuel. The fuel treated may be in compact or pulverized form and may be treated as a fluidized bed mixed with an inert powder, e.g. Ca or Mg fluoride or Al 2 O 3 . The C1F may be diluted with nitrogen or argon; oxygen may be added in order to remove stainless steel canning from the fuel. The condensed UF 6  and Cl 2  may be separated by distillation and the Cl 2  reacted with F 2  to produce C1F for use in the reaction. Pu may be volatilized from the residue by treatment with fluorine.

Title: Fitting for a large-diameter rubber or synthetic plastic hose subjected to high loads, and method of fixing said fitting on to the hose
IPC: F16L33/01
Filed: 1956-12-07
Abstract: 805,911. Hose end fittings. NEUE ARGUS G.m.b.H. Dec. 7, 1956 [April 25, 1956], No. 37518/56. Class 99(1). In a hose fitting for large diameter reinforced rubber or synthetic plastic hose 1 comprising an outer covering la which is removed from wire reinforcing layers 1b, 1c as shown and is replaced by material 4 harder than the removed layer such as metal or synthetic plastic cast in a hose socket 2, the internal diameter of the socket 2 increases towards the hose end and the ends of the wires 1b 1c are bent back preferably outwards so that they can take tractive force exerted on the completed fitting. In assembling, the socket 2 is fitted over the hose end 1 and the layer 1a is removed as far as the end step 2b, the ends 1e of the wires being bent backwards preferably over 180 degrees. A wedge shaped ring 3 is inserted between the wires 1b 1c and the hose core 1d and is fixed vertically in a mounting device not shown to receive the sealing material 4, the device being removed when the material has set and any surplus material being cut away to leave the end face flush. A nipple 8 is then inserted in the hose core 1d and is forced by means of bolts 10 on the nipple head 5 to bear against the core 1d with a sealing action. A greater force acting on the face 8c by the pressure medium in the pipes causes axial displacement of the nipple 8 as shown in the lower half of the Figure and ensures fluid tightness. The piston portion 8b of the nipple is sealed by an O-ring 9 to the inner wall of a sleeve 6 which in turn is located in the inner bore 5a of the nipple head 5 to which it is sealed by an O-ring 7.
