Title: Axial flow combines
IPC: A01F7/06
Filed: 1974-06-27
Abstract: 1475526 Axial flow combine INTERNATIONAL HARVESTER CO 27 June 1974 [29 June 1973] 28542/74 Heading A1F In an axial flow combine a frusto conical crop measuring section 54 of a rotor casing 30 houses a vaned impeller 34 for moving the crop rearward to crop threshing and separating mechanisms. Internal helical fins 115 act as guides .for the crop. As shown, the impeller 34 comprises three vanes 114 mounted on a support 120 on a rotor 74 of the rotor 32, the outermost edges of the vanes describing a cone similar to the frusto conical section 54 when they are rotated. Two transition members one comprising an upper sheet 140 and a channel member 82 and the other a lower sheet 142, define a crop feed opening 145 to the region 54 and are slanted in opposite directions such that as the vanes 114 rotate, they impart a rearward movement to the crop (Figure 9). The rotor shaft 74 is supported at its forward end in a bearing assembly 76 mounted on the channel member 82 itself mounted on a chassis. The assembly 76 comprises a bearing casting 78 having a radially extending portion 80 which diverts crop away from the rotor shaft 74 to prevent binding of the crop thereon. The bearing assembly 76 comprises a spherical bearing including an inner race member 166 on the shaft 74 and an outer race member 168 mounted in an inner cylindrical wall 162 of the casting 78. The central support 120, carrying the vanes 114, has a sealing portion 170 which projects into a recess 160 of the casting 78 to form with an outer cylindrical casting wall 164 a dust seal for the bearing assembly 76 (Figure 6). The helical fins 115, on the inside wall of the frusto conical impelling section 54, impart a rearward motion to the crop as it is rotated. Rearward of the crop impelling region are threshing and separating regions in which three blades 114, carrying rasp bars 110 in the threshing region only, cooperate with concave 56 and a grate 58. The blades 114 are supported on arms of spiders (Fig. 3, not shown) which are spaced along the rotor shaft) 74. The threshed and separated grain falls through the concave 56 and grate 58 to be cleaned by a blower 40 and eventually collected by an auger 42.

Patent GB-714611-A (GB)
Title: A process for recovering valuable products from substances separated from glyceride oils
IPC: A23J7/00
Filed: 1951-12-12
Abstract: Valuable products comprising fatty acids, sterols, choline, inositol, glycerine and other materials including complex compounds containing nitrogen and phosphorus, are recovered from substances separated from crude glyceride oils, which substances contain substantial amounts of phosphatidic material, e.g. gums, by subjecting a mixture of such substance to an excess of water while under superatmospheric pressure to a high temperature substantially above the boiling point of water at atmospheric pressure for a sufficient time to split the phosphatidic material; and separating the resulting mixture into a phase of fatty material substantially insoluble in water and an aqueous phase containing water-soluble materials.  The process may be carried out at 350-600 DEG  F. for a time range between 10 minutes and 8 hours, shorter times being employed for the higher temperatures and longer times for the lower temperatures.  Prior to separation of the two phases, the split material is cooled, and the water-soluble materials, e.g. inositol, recovered from the separated aqueous phase by extraction with a solvent, e.g. methanol, the inositol being recovered from the methanol insolubles.  The sterols and fatty acids are separately recovered from the separated aqueous phase by treating same with a volatile agent to produce two phases and vaporizing said agent from each phase to produce sterols and fatty acids.  The phosphatidic substance may be de-oiled before being split by counterflowing said phosphatidic substance and water in a chamber. The separated fatty material may be treated with propane to produce an upper layer largely composed of light-coloured sterols in solution in propane and a lower layer largely composed of fatty acids in propane.  Alternatively the fatty acids and sterols are separated from each other by adding ammonia and separating the upper sterol containing layer from the lower aqueous layer containing ammonia soaps of fatty acids from which the fatty acids are obtained by heating.
