Title: Improvements in and relating to the treatment of corn for the production of starch and related products
IPC: C08B30/04
Filed: 1937-07-13
Abstract: 499,200. Starch. INTERNATIONAL PATENTS DEVELOPMENT CO. July 13, 1937, No. 19420. Convention date, Oct. 17, 1936. Addition to 485,167. [Class 121] In a wet starch process, the starch-gluten mixture obtained after removal of germs and slop is subjected to a succession of centrifuging operations to separate the gluten from the starch, the overflow and, if desired, the underflow streams from each centrifugal being subjected to a flotation treatment to remove gluten and air therefrom and to yield relatively clear water from the overflow stream for reuse in the process. In the form shown, the maize is steeped at A and passed through the wet starch system B, the mill starch produced being partially dewatered in the filter C and passed to the centrifuge D. The overflow (gluten) passes to a flotation device E from which concentrated gluten passes to settler M and press N, clear water being delivered by pipe 20 to dilute the cake from filter C. The underflow (starch) passes to a flotation device F, from which gluten passes to the settler M and starch in part to the first centrifugal D and the remainder to the second centrifugal G. The overflow from G passes to device E<1>, from which the gluten of the froth passes to settler M, middlings water to a cone settler L, and the settlings (mostly starch) back to centrifugal G. The underflow from G passes to a device F<1>, from which most of the starch is returned to centrifuge G as wash water, the remainder being dewatered and washed before delivery at 44. All of the process waters, except the steep water and the water absorbed in the discharged solids, is re-used in the process.
Patent GB-761109-A (GB)
Title: Improvements in or relating to aconitic esters as synthetic lubricants
Filed: 1954-07-02
Abstract: The invention comprises aconitic triesters derived from aconitic acid and alcohols obtained by an oxo-synthesis from an olefine containing 7 or more carbon atoms or a mixture of the glycol monoethers of said alcohols.  It is preferable to derive the oxo-alcohols from olefines having from 7 to 17 carbon atoms, the C8 oxo-alcohols being particularly useful.  The preferred esters are those having an A.S.T.M. pour point below 35 DEG  F., a flash point above 300 DEG  F. and a kinematic viscosity at 210 DEG  F. within the range of 2 to 60 centistokes.  Olefins obtained from petroleum products and heptenes, diisobutylene, tri-isobutylene, C9 olefines and tetrapropylene are olefines from which the oxo-alcohols may be derived.  Glycol monoethers of oxo-alcohols from which the desired esters are prepared may contain diethylene glycol mono-isodecyl ether, dipropylene glycol mono-isooctyl ether, ethylene glycol mono-isotridecyl ether and tetraethylene glycol mono-isoheptyl ether.  The esters may be prepared by esterifying aconitic acid with the oxo-alcohols or the glycol monoethers of said oxo-alcohols.  In the example a tri-C8 oxo aconitate is prepared by refluxing aconitic acid, C8 oxo-alcohols, heptane and sodium bisulphate.ALSO:Lubricating compositions comprise a mixture of aconitic triesters derived from aconitic acid and from a mixture of alcohols obtained by an oxo-synthesis from an olefine containing 7 or more carbon atoms.  The prefered cormpositions are those having an A.S.T.M. pour point below 35 DEG F., a flash point above 300 DEG F. and a kinematic viscosity at 210 DEG F. within the range of 2 to 60 centistokes.  The triesters may be blended with other synthetic lubricants such as dibasic acid esters, complex esters and polymerized hydrocarbons, or with mineral oils.  Other additives which may be present in the compositions are viscosity index improvers, pour point depressants, detergents, antioxidants and rust inhibitors.

Filed: 1947-07-23
Abstract: 677,512. Printing machines. MINNESOTA MINING & MANUFACTURING CO. July 23, 1947 [Aug. 17, 1944], No. 19748/47. Addition to 642,915. Classes 100 (ii) and 100 (iv). [Also in Group VIII] The tympan sheet or blanket described in the parent Specification comprising a flexible backing 11 with a surface of uniformly-sized small globular bodies or beads 10 secured on a coating of adhesive 12, is modified by the beads being submerged in the adhesive to a depth greater than their radii. The beads may be of lime soda glass, iron, steel or other metals or alloys, ceramic material, or synthetic resin having the required toughness &c. Woven fabric, wood pulp, rope paper, rubber sheeting, rubber-coated fabric, and synthetic resin sheets, or combinations thereof, are mentioned as suitable for the backing.. Also, a paper which has been treated with material such as glue or zein to render it oil or grease proof may be used. The blanket should be impervious to ink and this may be achieved by coating the front or back face of the backing 11 with a glue and glycerine composition or an alkyd resin or a synthetic rubber 38 which is non- reactive to the ink and insoluble in cleaning fluid. If the backing is porous it may be saturated with the composition. Alternatively, an interior layer of the impervious composition may be provided. After the beads have been set in the adhesive, a thin sizing coating 37 may be applied to the beads to secure them more firmly and to provide an ink-repellent surface. The beads may be roughened by sand-blasting, or by etching before they are applied, so as to increase their frictional resistance. Alternatively, they may be sized with a composition containing fine particles. An hydrophilic surface may be provided on the beads by such roughening treatment or a film of sodium silicate or other suitable substance may be applied for the same purpose. An organophilic surface may be formed by a finishing coat of acrylate, or an alkyd resin, or natural or synthetic rubber. Specification 433,128, [Group XXIII], also is referred to. According to the Specification as open to inspection under Sect. 91, the material may be employed (a) as a backing during the cutting of duplicating-machine stencils (b) as slip sheeting between coated or printed sheets or webs (c) for upholstery covers and vehicle seat covers (d) as a covering for guide rollers 36, Fig. 5 (Cancelled), or 26, 28, Fig. 4 (Cancelled), contacting the wet face of a web in respectively a paper coating machine or a cloth finishing or coating machine. If cloth is being coated with starch, the adhesive 12 and the film 37 may be a phenolic resin. This subject-matter does not appear in the Specification as accepted.

[Class 40 (iii).] A Kerr cell 24 comprises electrodes spaced apart by glass sheets the edges of which are fused together. The whole is mounted in a glass vessel 2, Fig. 1, the wall of which may be either curved so as to focus the light-beam or flattened so that the beam passes through plane surfaces (Fig. 2, not shown). Copper wires 12, 14 pass through the pinch 4 and are connected with nickel wire supports 8, 10, to which opposite poles of the cell are screwed or welded at 18, 22. The vessel is, after preliminary exhaustion, filled through a pipe 6 with nitrobenzene, benzonitrile, nitrotoluene, carbon disulphide, mustard oil or senfol ; precautions against the promotion of bubbles are described. In the formation of the cell 24, from nine to eighteen annealed sheets of electrolytically prepared nickel, 0.002 inches thick, are washed in alcohol, ether and nitric acid and are burnished. They are spaced apart at their edges by glass slips 0.011 inches thick, and are clamped between two glass plates. The assembly so formed is subjected to a heating and annealing process as a result of which the glass plates and spacers are fused together at their edges and a rigid structure is formed as shown in Fig. 4. The nickel plates have lugs 48 which are connected together alternately. These may be on the same side of the plates as in Fig. 4 or alternately on opposite sides as in Fig. 1. The dielectric is purified and occluded gases are liberated by the application of a potential difference for some time before sealing. The electrostatic capacity of the cell may be reduced by shaping the plates and spacers so as to form a wedge-shaped path for the non-parallel beam of light (Fig. 5, not shown). The invention may be applied to the cells described in Specification 401,311. Specification 391,931 also is referred to.
