Title: Devices for milking machine units
IPC: A01J5/04
Filed: 1974-05-03
Abstract: 1451995 Milk tube valve ALFA-LAVAL AB 3 May 1974 [4 May 1973] 19574/74 Heading AIM A flap valve unit 2, 3, 4 is inserted in the milk tube and activated by the milk flow, which allows milk to flow away from the teat cup, but prevents or inhibits flow towards the teat cup. The valve unit 2 comprises a sleeve 3 and a valve flap 4. The outside of the sleeve is cylindrical at one end and tapers at the other end. Internally, the sleeve has a stepped bore. An annular face 6 between the wide and narrow bores forms the seating for flap 4. The flap 4 consists of a disc of elastic material with a tongue 9 adapted to pass through a slot 10 in the wall 11 of the wider portion 7. In use, the valve unit 2 is placed in the milk tube (not shown), of similar bore to the smaller valve unit bore, with the tapered portion towards the teat cup and the tongue 9 retained between wall 11 and the inner surface of the milk tube, and folded so that the flap 4 is elastically biassed towards its seating 6. Flap 4 opens when milk flows from the teat cup, and closes when the flow is reversed. The impedance to reverse flow can be reduced by providing a central aperture (not shown) in the flap.

Title: Process for improving lubricating oils
IPC: C10G50/02
Filed: 1935-07-10
Abstract: Polymerized hydrocarbons used for improving liquid hydrocarbons are obtained by treating mixtures of propylene and ethylene, or gases containing such mixtures, with polymerizing agents such as boron fluoride or chloride of aluminium, zinc, or iron at below 0 DEG  C. Reaction-accelerators such as mercuric chloride, or retardants such as water, aluminium oxide, or zinc oxide may be present, the pressure may be normal or raised, the reaction mixture may be heated to normal temperature after the main reaction has ceased, and the polymers may be formed in presence of the liquid hydrocarbons.  In example (2), 100 lb. of mixed propylene, ethylene, ethane, propane, and methane, obtained from coke-oven gas by adsorption or cooling, are fed during 5 hrs. into 20 lb. of a paraffin oil containing 10 lb. of twice-used aluminium chloride, a temperature of -30 DEG  C. and a pressure of 9,5 atmos. being maintained.  After 10 hrs. the temperature is allowed to rise to atmospheric, the pressure is relieved, and the hydrocarbons are dissolved out in petroleum ether, purified by 30 per cent sulphuric acid and 30 per cent caustic soda, and freed from solvent.  Specifications 293,487, [Class 2 (iii)], 358,068, and 432,310 are referred to.ALSO:Liquid hydrocarbons are improved by adding polymerization products obtained by treating mixtures of propylene and ethylene, or gases containing such mixtures, with polymerizing agents such as boron fluoride or chloride of zinc, iron, or aluminium at below 0 DEG  C.

Title: Aluminium purification
IPC: C22B21/00
Filed: 1958-06-20
Abstract: 892,929. Purifying aluminium. MESSNER, G. June 20, 1958, No. 19870/58. Class 82(1). Pure aluminium is obtained by entraining crude aluminium or aluminium alloy in a' flow of liquid mercury or mercury alloy through a digestion region at more than 400‹C., cooling the impure amalgam to below the saturation temperature of the aluminium contained in the amalgam so as to separate insoluble material cooling the resulting purified amalgam to recover pure aluminium. In the apparatus shown in Fig. 1, liquid aluminium alloy from a crucible 2 and mercury from a pump 3 are fed to a mixing chamber 4 and the resulting mixture of mercury and solid alloy particles are passed through a digestion region constituted by a screw conveyer 10. Some insoluble material is removed by a conveyer 14 and the impure amalgam is sprayed by a nozzle 11 into a vessel 17 containing mercury at reduced pressure thereby precipitating the remaining insoluble material 27. This is removed by a screw conveyer 28. The purified amalgam is removed by a line 33 and sprayed by a nozzle 15 into a vessel 35 containing mercury at reduced pressure whereupon the dissolved aluminium crystallises out. The resulting paste is transferred by a conveyer 37 to an enclosure 39 and is squeezed between rollers 41, 42 to separate the aluminium from the mother liquor which returned to the mercury circuit. The aluminium is passed by a conveyer 43 to a furnace 44 where any adherent mercury is distilled off. In another form of apparatus described, Fig. 2 (not shown), (1) the liquid aluminium alloy and the mercury are mixed by spraying them together into a mixing chamber, (2) the impure amalgam is cooled by injecting it into a body of cooled mercury, and (3) this mercury is cooled by causing it to vaporize a liquid hydrocarbon. Figure 4 shows an alternative form of digestion device in which the mixture of incompletely dissolved aluminium alloy and mercury is sprayed from a nozzle 79 into a tank 78 containing a layer 80 of undissolved aluminium alloy and insoluble material. The impure amalgam is removed at 82.
