Patent GB-536027-A (GB)
Abstract: 536,027. Extracting zein. CORN PRODUCTS REFINING CO. Oct. 27, 1939, No. 28876. Convention date, Dec. 22, 1938. [Class 2 (iii)] In the extraction of zein from corn gluten by an alcohol such as ethyl or isopropyl alcohol and removing the oil and colouring matter from the extract by means of a hydrocarbon such as benzene or hexane, water is added to the mixed solvents in such quantity as to effect a partial separation of the solvents without causing precipitation of zein and the remaining alcohol is separated from the hydrocarbon preferably by first distilling to separate the oil and then adding further water. The water may be in the form of a 10 per cent. alcohol produced by precipitation of the zein from the alcoholic solution. In an example, zein solution in isopropyl alcohol (85 per cent.) is mixed with hexane in a mixer 6, the hexane layer being taken off to a vessel 15 while the alcoholic zein solution is heated by alcohol vapour in a heater 8, hexane is expelled as vapour at 9 and water is added at 10 to precipitate the zein ; the zein precipitate is treated to form a pasty dispersion at 11 and is spray-dried at 12. The dilute (10 per cent.) alcohol from 10 is added to the hexane in 15 so as to produce an alcohol of concentration about 50 per cent. on distillation at 16 and more of the dilute alcohol is added to the hexane still residue at 17 so as to yield an alcohol of about 18 per cent. Dilute alcohol vapour obtained by distillation of the alcohol from 15, 16 and 17 and alcohol vapour obtained by steaming the gluten meal residue are treated in an alcohol still 19 to recover the alcohol. Fig. 2 shows in greater detail the treatment of the hexane layer from the vessel 7 which passes by a pipe 22 to the vessel 15 through a nozzle 54 where it is mixed with dilute alcohol from the zein precipitator 10 by a pipe 23. Hexane is distilled at 16 and is collected in 17 where more of the dilute alcohol is added. The alcohol still 19 comprises : a central part 35, a lower stripping-column 36 and a rectifying column 37 connected with a condenser 38. The part 35 has an overflow pipe 40 and capped vapour pipes 41. The 50 per cent. alcohol enters by pipe 24, the 18 per cent. alcohol by pipe 32, both in the middle section, and the slop from the hexane still through pipe 33 and the alcohol and water vapour from the meal steamer by pipe 53, both in the bottom section. The zein remaining in the alcoholic part of the solvent mixture does not precipitate in any quantity until the dilution is considerable and owing to the long stay of the dilute alcohol in the middle section of the still 19 where the alcohol is dilute precipitation occurs in a finely-divided state. Specification 536,024 is referred to.

Abstract: 1,111,518. Hydraulic apparatus. OLEOMAT. Dec.1, 1966 [Dec.2, 1965], No.53742/66. Heading F1P. Hydraulic apparatus includes three rams V1, V2, V3 that are controlled by valves D1, D2, D3 such that the rams V2, V3 can be connected in either series or parallel with each other so as to regulate the speed and thrust developed by these rams. The said valves are of conventional kind and include members that can be set in any of three positions a, b, c. As shown in Fig.3, when any of said members is in the position b the associated ram is disconnected from a pump P and a reservoir R for hydraulic fluid without effecting discontinuity of the hydraulic circuit; and when any of said members is in either of the other two positions, the associated ram is connected so that it operates in one direction or the other, the fluid expelled by the rams V1, V2 being directed into the next ram in the circuit. To obtain parallel connection of the valves V2, V3, the movable member in the valve D2 can occupy a fourth position d wherein the uppermost end of the associated ram V2 is connected to the output side of the valve D1, the opposite end of said ram being connected directly to the reservoir R through a valve U comprising a movable member that can occupy either an "open" position # or a "closed" position # and is coupled to the said member in the valve D2 by lost-motion linkage x, which is such that the valve U is closed except when the latter said member occupies the position d. Additionally, when the position a is assumed, the output side of the valve D2 is connected to the input side of the valve D3, as shown in Fig. 4. The apparatus may be incorporated in a mechanical shovel and may also include a rotary M and a pair of additional rams Z, which motor and rams are controlled by valves D4, D5, respectively, these valves being similar to those controlling the rams V1, V2, V3. The valve D2 may include a member that can occupy yet another position wherein it effects connections similar to those effected in the position d save that the lowermost end of the ram V2 is connected to the valve D1 while the uppermost end is connected to the reservoir R through the valve U.

The axes are maintained horizontal when subject to light such that the plants fix carbon by photosynthesis; to reduce the respiration rate under low light intensity conditions the axes are periodically tilted from the horizontal when these conditions obtain. The plant beds 130 are carried by hollow shafts 131 rotatably mounted in carrier members 110 which are rotatably mounted about a stationary shaft 115. The carrier members 110 are rotated by an electric motor 121 and carry a planet pinion 162 meshing a stationary sun gear 161. The planet pinion 162 is fast with a sprocket driving by way of a chain, sprockets fast with the plant bed shafts 131. The shaft 115 of the carrier members is fixed to supports 101, 102 and hydraulic motors 202, 203 are sequentially energised under conditions of low light intensity to alternately raise the supports 101, 102 and tilt the plant beds. Liquid is supplied to the plant beds through their shafts 131, liquid being supplied to the apparatus by way of a distributor 170 whence it is supplied to each end of the hollow shafts 131 as they are brought beneath the level of shaft 115 by rotation of the carrier. The shafts may be simply perforated to supply liquid to the beds, or they may communicate with radial tubes 460 having apertures 463 which are protected by plastic shields 465. The plant beds may take various forms: they may be formed by individual pots mounted in peripheral rows along the surface of a cylinder, they may be formed by rooting medium inserted in annular cylinders having perforations 141, 142 accommodating the plants, or they may be formed by selfsupporting cylinders of rooting medium.
