Title: Method for uniform dyeing of cellulose acetate
Inventor: GALATIOTO LUIGI C
IPC: D06P1/00
Filed: 1946-06-19
Abstract: Cellulose acetate fabrics are cleansed, wetted uniformly with an impregnating liquid containing no dye or other colouring matter, and while still uniformly wetted are treated with a dye bath containing a solvent for the fabric and for the dye in solution therein and which is also miscible with the wetting liquid.  One or more solvents may be added to the dyebath subsequently.  The impregnating liquid may itself contain a solvent for the cellulose acetate.  In examples, the fabric is scoured and rinsed and uniformly wetted with water with or without a wetting agent such as an alkali metal sulphonate, and with or without a solvent for cellulose acetate such as Cellosolve (Registered Trade Mark), formic acid or acetic acid, and is then dyed in an aqueous bath containing: (1) formic acid, Cellosolve, Alizarin Cyanin Green GHN and Amido Yellow, followed by later additions of formic acid and Cellosolve; (2) formic acid, acetic acid, sulphuric acid, National Direct Blue RB, Alizarin Gyanin Green GHN and Alizarin Irisol R; (3) formic acid, sulphuric acid, Azo Rubinole 3GP and Supramine Yellow RA; (4) formic acid and Calcocid Blue Sky; (5) formic acid, propionic acid, Alizarine Cyanine Green GHN and Alizarine Supra Blue A; (6) acetic acid, sulphuric acid, Alizarine Supra Blue A and National Direct Blue RB; (7) acetic acid, propionic acid, sulphuric acid Azo Rubinole 3GP, Wool Fast Blue GL and Supranol Yellow 2GA, and (8) ethylene chlorhydrin and Alizarine Supra Blue A.

Title: A process for isomerising fatty oils and fats
IPC: C11C3/14
Filed: 1938-06-21
Abstract: 502,390. Hardening fats and oils. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. June 21, 1938, No. 18471. Convention date, May 12. [Class 91] Fats and fatty oils, are isomerized whereby the melting point is raised, by heating at 100 to 200‹ C. with sulphur dioxide preferably dry and under sufficient pressure to maintain it in the liquid state. The oil or fat may first be freed from peroxides and dissolved oxygen. The isomerized product may be separated into fractions of different melting point by solvent treatment. In examples, palm, olive, or cotton-seed oil is treated with a stream of nitrogen, after which the oil is heated at 110-165‹ C. with sulphur dioxide under pressure. The product is separated from the solvent, and may be treated with acetone or sulphur dioxide to obtain a high melting fraction. The products are solid edible fats of light colour, and retain the nutritive properties of the original oil. Specification 462,665 is referred to.

Apparatus for forming longitudinally seamed tube from flexible strip material by knitting together tabs 12 and recesses 13 formed along the edges of two lengths of the strip 11, comprises a strip-feeder conduit 18 descending at 19 with side-by-side flat passages 38 (Fig. 7) into a horizontal portion 21 wherein each passage becomes increasingly transversely curled towards the other (Fig. 9). The apparatus is assembled behind the mole 15 of a mole plough attached at 20 to a coulter 16; the strip 11 being carried on two spools 25 mounted on the arms 26 of a Y-shaped bracket which is seen in sideview in Fig. 1. The flat strips from the upper conduit portion 19 are swept through 90 degrees into conduit portion 21 by being folded outwards around smoothcurved surfaces 31 inclined at 45 degrees to the vertical in the corner box 22 which may be detachable. The curled passages 38 in the conduit portion 21 have their axes diverging slightly from each other but lying in parallel planes (Fig. 9). At the end of the conduit is a former-die 23 in which the edges of the curled ducts intersect to introduce the tabs 12 of one strip into the slots 13 of the other, forming a continuous tube 10 which emerges from a sleeve 28. In use the strips 11 from the spools 25 are pushed through the conduit 18 by hand as far as the die 23 through which they are drawn from the rear with a hook and the end of the newly-formed pipe anchored in the soil at depth before the mole plough is advanced to continue the operation automatically. The strip is made of high-impact strength polyvinyl chloride. Specification 975,654 is referred to.

Abstract: 806,757. Nuclear reactors. ROLLS-ROYCE Ltd. June 18, 1957 [June 18, 1956], No. 18863/56. Class 39(4). Reactivity of a nuclear reactor is controlled by varying the distance which rod-like fuel elements extend within hollow neutron absorbers, in the form of a grid, this grid being displaced length-wise of the fuel rods by a hydraulic or pneumatic ram. Vertical fuel elements 15 of hollow hexagonal section are mounted for limited universal movement in a plate 14 within a pressure vessel 10. The absorber grid 22 is in six segmental sections, each mounted on a carriage 27 sliding on two vertical guide bars 26. Coolant water forced in through a hollow piston 34 raises the grid 22 until an adjustable stop 52 causes a valve 45 to open. The grid 22 surrounds the upper ends of the fuel elements during operation and can be lowered quickly by venting the piston 34 to a low pressure container. A lining 18 surrounds the reactor core. The reactor may be cooled by liquid sodium or it may be gascooled in the case of a pneumatically actuated absorber grid. Specification 790,487 [Group XXIV] is referred to.

The drag between the inner and 'outer races of the bearings 1 urges the blade 4 and the cutters 3 together and the inner races are rigidly connected to the shaft 7 by sleeves 11. The bearings 1 are arranged along the shaft 7 so that at any instant each cutter 3 has a counterpart moving in anti phase relationship and so thereby inertia forces are balanced. The blade 4 may be segmented, with each section supported on the shaft 7. Each cutter may be attached to its respective bearing 1 by a holder having a leaf spring to resiliently bias the cutter into its working position but allow deflection upon the cutter encountering an obstacle. The cutters 3 may have a trapezoidal (narrow side uppermost) or triangular vertical cross-section or a V-shaped vertical cross section (Fig. 11) in which the angle subtended by the arms of the "V" varies from the rear to front end by an amount equal to twice the angle which the cutter is tilted about its longitudinal axis as it sweeps over one edge of a tooth of the blade 4. In another embodiment, the horizontal angle contained between the cutting edge of each cutter 3 and the associated tooth edge of the blade 4 is maintained constant by the tooth having a rounded as opposed to a rectilinear cutting edge. The drive shaft 7 may have a circular or polygonal cross section and the sleeves 11 attached thereto by splines or screw threads. A bellows like sleeve is fitted over the drive shaft 7 to prevent entanglement of cut crop.
