Patent GB-593180-A (GB)
Title: Improvements in and relating to the contacting of solids with solids
IPC: B01J8/32
Filed: 1945-06-13
Abstract: Solids are contacted with solids by continuously feeding to a vessel a particulate solid which is maintained in the fluid state as defined in Specifications 569,691 and 582,055, [Group XII], by the upward passage through it of a gas, the particles moving relatively to another particulate solid in the vessel, and continuously removing the first solid from the vessel at a point remote from its entry. The second particulate solid may be retained within the vessel in the unfluidised or fluidised state, or may be continuously fed to the vessel and removed therefrom, so as to attain countercurrent flow between the solids.  When the second solid remains in the vessel in the unfluidised state, the first solid may pass either up or down the vessel, i.e., in co-current or counter-current with the fluidising gas.  The process may be used for the temperature control of one of the solids by contact with the other solid, or one of the solids may be a catalyst for a reaction between constituents of the fluidising gases, and the other solid a substance which will remove undesired reaction products.  In the catalytic treatment of water gas with steam to increase its hydrogen content, lime may be used to remove carbon dioxide.  An example describes the contacting of sand and magnetite.

Title: Improvements in the manufacture of synthetic resins
IPC: C08G12/12
Filed: 1940-10-07
Abstract: 545,081. Resinous condensation products;  coated fabrics. CALICO PRINTERS' ASSOCIATION, Ltd., LANTZ, L. A., and SCHOFIELD, A. Oct. 7, 1940, No. 14969. [Class 2 (iii)] [Also in Group VIII] A synthetic resin pre-condensate is prepared by first reacting a formaldehyde polymer with a polyhydric alcohol by heating the mixture until the formaldehyde polymer dissolves, and then reacting the mixture with a urea substance, added slowly in order to control the reaction. Specified polyhydric alcohols are glycerol and polyglycerol, and specified urea substances are urea, thiourea, guanidine, cyanamide, dicyandiamide and melamine. The temperature of the mixture, when the urea substance is added, is preferably about 80‹- 90‹C. The precondensate, when heated in the presence of an acid catalyst, is converted into a soft, resilient and transparent resin, whose softness may be further increased by the addition, to the precondensate, of seaweed mucilages such as Irish moss, carragheen or agar-agar. The properties of the final resin  may also be modified by dissolving in the precondensate synthetic resins of the polyvinyl, polyacrylic and alkyd types, alkyl celluloses or chlorinated rubber. The precondensates may be used for impregnating or coating fabrics, and as adhesives for the fixation of pigments and fillers on fabrics, by printing, impregnating or coating, the coatings being fixed by heating in the presence of an acid catalyst, e.g. ammonium sulphate. An open net fabric, previously combined with a sheet of transparent regenerated cellulose, may be coated in this manner, and used as a replacement for window glass. Examples are given. Specification 256,248, [Class 2 (iii)], is referred to.

When the coils are compressed to the required extent, each pair of crescent-shape members 49, 50, Fig. 5, closes a path across a respective slot 18, Figs. 1, 4, in the compacting head so that a respective binding wire starting from a supply 58 follows a path 28, 41, 52, 51, 41 and 29 and returns to the binding unit 3 after which the wire is released from the paths 41 by pivotal movement of portions 42 about their pivot pins (44), Fig. 6, (not shown), and the wire is then tightened so that it embraces the inner and outer surfaces of the coil firmly. The two ends of each wire are then twisted by a twisting unit, the excess wire cut away by shear cutters 31 and the ends folded back by forked members 38. The carriage 2 along with the bound coil is then retracted and the cradle 11 tilted by an hydraulic jack (14) so that the coil leaves the cradle 11 under gravity and discharged on a sloping platform (15), Fig. 3 (not shown). The machine may be entirely automatic, semiautomatic or manually-operated.

Title: Improvements in and relating to the production of high grade cellulose
IPC: D21C5/00
Filed: 1938-05-20
Abstract: 501,999. Obtaining cellulose; cellulose esters. WIGGINS, TEAPE, & CO. (1919), Ltd., and EDGE, S. R. H. May 20, 1938, No. 15080. [Class 2 (ii)] High grade cellulose is obtained from grasses, reeds, and like materials by boiling them in an aqueous alkaline solution to loosen the fibres one from another and from encrusting materials, and then separating the long fibre constituent from the mass of loosened fibres. The boiling treatment is such that the elementary fibre cells are obtained, the longest of these seldom exceeding 3 mm. The separation process is effected so that the average cell length of the long fibre constituent is about 1À5 mm. Caustic soda solutions of 3À5 per cent strength may be used for the boiling treatment which may be carried out under increased pressure for several hours. Separation of the long fibres from the short fibres may be effected on a drum washer or by causing the fibre suspension to flow over an inclined screen of appropriate mesh. The screen may be given a reciprocating motion. Another method of separating the fibres consists in passing the fibre suspension through a tube made of a wire mesh, so that the short fibres pass through the mesh whilst the long fibres traverse the tube. The action of the tubular wire filter may be assisted by reciprocation or by centrifugal action. Esparto, bagasse, sulina reeds, or kuru-kuru grass may be used as raw material. The high grade cellulose obtained may be used for the production of cellulose esters such as cellulose nitrate and may be employed in the artificial silk industry.

Abstract: 376,896. Variable speed gearing. IMPERIAL CHEMICAL INDUSTRIES, Ltd., Mill bank, London, and GREENWOOD, J. E., 1, Stubbs Road, Wolverhampton. May 22, 1931, No. 15147. [Class 80 (ii).] Relates to ratchet control gear for motor cycle and other variable-speed gearing of the type in which a control lever returns to central position after each operation, successive movements in one direction stepping the gear up and in the other direction stepping it down. The control-lever 15 is formed with two pawls 17 at one end and turns on a pivot 14 on an arm 12 loose on the spindle of a ratchet wheel 10, which operates two shifting-forks 5 by a toothed segment 7, pinion 6, and cam drum 4. A light spring 20 carried in the lever 15 presses a plunger 19 into engagement with cam faces 13 on the arm 12 to return the lever and arm to alignment, and a strong spring 23 in the casing forces a plunger 22 against the faces 13 to return the arm and lever to central position. On movement in either direction, the lever 15 rocks on the pivot 14 to engage one pawl 17 with one of its co-operating ratchet-teeth 11, when the arm 12 and lever 15 move together until the arm strikes a stop 24. In a modification, the plunger 19 is dispensed with and the pawls 17 are carried in a lever secured to the lever 15, which is operated by a linkage spring-returned to central position. An indicator may be secured to the ratchet wheel 10.

Title: Improvements in or relating to the manufacture of cellulose esters
IPC: C08B3/02
Filed: 1933-05-25
Abstract: Cellulose esters are prepared with the aid of concentrated or anhydrous hydrogen fluoride in amount equal to or greater than the weight of the cellulosic material, preferably 4--6 times its weight. The esterifying radicles may be derived from unsaturated or saturated aliphatic acids, aromatic acids, and heterocyclic or alicyclic acids, or from inorganic acids, such as cellulose nitrates.  The esterification is preferably carried out at from 0 DEG  C. to 25--30 DEG  C., although temperatures below 0 DEG  C. may be employed; the esterifying agent may be the acid anhydride, acid chloride or keten, or even the acid such as fuming nitric acid; and it may be employed in theoretical quantity, it being possible to obtain directly cellulose esters with any desired ester content; the esterification may be carried out in the presence of a solvent such as the acid corresponding to the ester desired, or sulphur dioxide; and the material to be esterified may be cotton linters, wood pulp, rayon, regenerated cellulose, or even lower esters or ethers of cellulose. Examples are given of the preparation of cellulose acetates, acetate butyrate, acetate laurate, caproate heptate, phthalate, and nitrate, and of ethyl cellulose acetate and propionate, and cellulose acetate nitrate. After completion of the esterification, the hydrogen fluoride may be recovered in large part by distillation, and the ester in solution precipitated by water, or by ether, methanol, ethanol or other anhydrous liquid miscible with hydrogen fluoride. The esters obtained may be used for lacquers, coating compositions, artificial fibres, plastics, adhesives, interlayers for safety glass &c.  The Specification as open under Sect. 91 refers to the use of halogen acids in general.  This subject-matter does not appear in the Specification as accepted.
