Title: Process and apparatus for converting starch and other polysaccharides into dextrose and maltose containing products
IPC: C13K1/06
Filed: 1964-07-09
Abstract: Starch and other polysaccharides are converted into dextrose and maltose containing products by subjecting the medium to be treated first to enzymatic liquefaction, and then to enzymatic saccharification, the process being characterized in that the medium, while being heated to the liquefaction temperature is pressed through slot-like passages under a pressure and at a velocity such that a substantial thixotropic reduction of viscosity is produced by shearing forces in the medium before the viscosity is reduced as a result of the enzymatic liquefaction and, after the liquefaction temperature has been reached and the viscosity has been reduced as a result of the enzymatic liquefaction, the medium is conducted through conduit means of a length such that during the passage of the medium through these conduit means, the liquefaction proceeds to a point where the product is no longer gelatinizable by cooling.

Title: Improved process for the manufacture of viscose rayon
IPC: D01F2/10
Filed: 1950-11-24
Abstract: Regenerated cellulose filaments are made by extruding into an acid spinbath viscose with which is incorporated a soluble cation-active compound having the formula RN. (Cn H2nO)x H. (Cn H2nO)y H, in which R represents an aliphatic hydrocarbon chain containing at least 8 carbon atoms, n is 2, 3 or 4 and the sum of x and y is at least 5, neither x nor y being zero.  R may contain 8-24 carbon atoms, preferably 12-14 carbon atoms, while n may be 2 and x + y about 14. Suitable cationactive tertiary amines may be prepared by condensing one mole of primary amines prepared from coconut oil or soya bean oil with 15 moles of ethylene oxide.  In examples such condensates are added to viscose in the proportions of 0.12 per cent. and 0.24 per cent. based on the weight of cellulose and spun in the normal manner at maturities of 9.8 DEG  and 11 to 11.5 DEG  Hottenroth with production of clear finished rayon.  The addition of the cation-active compounds to the viscose inhibits milkiness of the filaments and reduces spinneret incrustation, even when the spinbath contains no cation-active material.

Abstract: 391,219. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London, and EWEN, H. A., Gray Walls, Priest Lane, Shenfield, Essex. Oct. 22, 1931, No. 29377. [Class 40 (v).] Relates to directional aerial structures for use on submarines. According to the invention, a directional aerial system, the wires of which are protected against water and weather, is mounted upon a carrier which can be telescoped within another carrier when the aerial is not required for use, the system being collapsed automatically by the action of telescoping the carrier. The telescopic structure may comprise more than two sections. In the construction shown, Bellini-Tosi aerials 1, consisting of rubber-sheathed wires, are mounted on a tubular support 2, which can be telescoped into an outer tube 3 secured to the main deck of a submarine. The aerial hoisting mechanism comprises two screwed rods 4 mounted in bearings within the tube 3, the rods being bridged by a member 9 carrying the tube 2 and containing nuts 10 which engage the screws. On moving a wheel 6 by hand or by a motor, wheels 5 gearing therewith rotate the screw 4, and the tube 2 is thereby pushed upwards. The aerial structure, which is of the kind described in Specification 371,476, opens automatically as the tube 2 ascends, the opening being effected by the weight of a sliding guide rod 11 assisted, it may be, by the action of springs 15. The folding-up of the aerial is brought about when the tubes 2, 3 are telescoped one into the other, by the engagement of arms 12 with tapered slots 13 in the top of the tube 3. A modified form of hoisting device, Fig. 7 (not shown), comprises a steel or like rope acting on a pulley at the base of the tube 2 and operated by a winch. The aerial tubular structure resembles and is installed in place of the pillar usually provided on a submarine with mine defence wiring, and the aerial structure serves for the attachment of such wiring. The mine wire defence may also support an additional aerial.
