IPC: A23L11/30
Filed: 1941-11-25
Abstract: 555,636. Treatment of flour. LANT, R. Nov. 25, 1941, No. 15187. [Class 58] Vegetable seed meal, particularly soya bean flour, is treated with an aqueous solution of a monohydric alcohol having an alcohol concentration of 35 per cent-60 per cent, producing an extract of a gummy consistency and a residue of albuminous and edible carbohydrate material. Methyl, ethyl, or propyl alcohol may be used, but isopropyl alcohol having a concentration of 48.5 per cent-55 per cent is pre ferred. Stronger concentrations remove the oil but not the objectionable flavour from the meal; weaker concentrations produce more protein dispersion. Treatment with strong alcohol (95 per cent) at a temperature of 40‹-50‹ C., may be followed by that with alcohol having a concentration of 35 per cent- 55 per cent. Granulation of the protein residue may be aovided by a further treatment with strong alcohol. Specifications 23595/11, [Class 58], and 361,956, [Group VI], are referred to.

Title: Improvements in or relating to jet noise silencers
Inventor: BROWN DAVID MORRIS
IPC: F02K1/62
Filed: 1956-05-18
Abstract: 825,642. Jet-propulsion nozzles. ROLLSROYCE Ltd. May 17, 1957 [May 18, 1956], No. 15670/56. Class 110 (3). [Also in Group XXXIII] A jet noise silencer for a jet-propulsion engine has means operable to divide the exhaust gas flow into a number of separate streams which diverge from one another, each stream having a maximum thickness substantially less than the thickness of the single jet stream which is obtained when the means is inoperative. The jet pipe and propulsion nozzle of a by-pass gas turbine engine, Fig. 1, comprises a parallel portion 14 followed by a divergent frustoconical portion and a further parallel portion. The latter portion has formed in its surface a pair of rectangular ports 16 and immediately outside these ports sets of deflector vanes 17. Two pairs of plate members 21, 22 are adapted to pivot about axes 20 spaced downstream of the end plane of the jet pipe. One of the plate members is segmental and corresponds to segment between the axis 20 and the periphery of this pipe. The other plate member is approximately rectangular and corresponds to the area between the axis 20 and the diameter of the jet pipe parallel to the axis. The plate members 20, 21 may be independently pivoted about the axis 20 by jacks located parallel to the axis of the jet pipe. In the position shown, in which the plate members 22 are axial and the plate members 21 are inclined to them at an angle of about 20 to 25 degrees, three jet streams are formed diverging from one another. This arrangement results in a marked reduction of noise and is used at take-off. For cruising, both pairs of plates are arranged axially and the thrust loss is a minimum. For thrust reversal, both plates are arranged in a plane at right angles to the jet stream in which position they are locked by hooks 23 operated by rams 24. The gas stream is then deflected through ports 16. The pivotal axes 20 need not be symmetrically disposed between the ports 16.

Abstract: A water resistant, grease resistant, oxygen resistant, polyolefin film comprises a polyolefin film bonded to a continuous, smooth, uniform, turpentine-impermeable, water-insoluble layer of retrograded "amylose."  The films may be prepared by: applying a film forming amylose composition on to a preformed self-supporting polyolefin film; applying a film-forming polyolefin composition to a preformed self suporting amylose film, or laminating a preformed, self supporting amylose film to a preformed self supporting polyolefin film.  The film may be bonded to a paper base e.g. natural kraft paper.  This multiply structure may be pepared by applying an amylose coating to one side of the paper and a polyolefinic coating to the other side; applying an amylose coating to the polyolefin side of a polyolefincoated paper; or applying a polyolefin coating to the amylose side of an amylose-coated layer, the coatings being applied as preformed films or as a suitable film-forming composition.  The term "polyolefin" refers to polymers comprising at least 50 mole % hydrocarbon monomers such as ethylene, propylene, butene, 1, styrene. Suitable comonomers include ethyl acrylate, acrylic acid, vinyl acetate, chloride. The term "amylose" refers to the amylose resulting from the fractionation of any variety of starch into amylose and amylopectin; whole starch composed of at least 75% amylose; simulated natural starches containing at least 75% amylose e.g. mixtures of separated amylose with amylopectin, or of corn starches having less than 75% amylose mixed with separated amylose; derivatives of amylose having a maximum degree of substitution of 0.15 and are water insoluble at 40 DEG C.  The amylose layer may be plasticised preferably with polyvinyl alcohol with less than 20 mole per cent of the monomeric units containing acetyl groups.  A list of other suitable plasticizer is given which includes polyhydric alcohols, amino-alcohols, hydroxyalkyl amides, quarternary ammonium compounds. The amylose layer may be applied as an aqueous solution at above the gellation temperature using a roll applicator and an air knife, the amylose then being allowed to gel.  The amylose retrogrades form the aqueous solution concurrently with gellation.  A plurality of amylose layers may be applied.  Other methods of application mentioned are coating with a doctor blade, spray applicator, wire wrapped rod, knife coating, trailing blade coater, size press.  Dry amylose compositions can be extruded on to the polyolefin film or polyolefin coated paper.  The polyolefin can be activated by: flame treatment; by chemicals e.g. by application of polyethylene imine, by ozone treatment; by glow discharge; by extrusion. Polyethylene may be extruded on to a preformed emylose film, paper or amylose-coated paper.  Methods of preparing self supporting emylose films are described.  Preformed amylose film and preformed polyolefin-film or polyolefin-coated paper may be laminated together using a polyethylene imine as a tie coat.
