Title: Process for the manufacture of nitrogenous cellulose derivatives
IPC: C08B15/06
Filed: 1935-07-29
Abstract: Cellulose compounds containing nitrogen are obtained by subjecting cellulose materials in the presence of a non-volatile inorganic alkali to the action of epichlorhydrin and ammonia or a basic substitution derivative of ammonia such as a primary, secondary, or tertiary amine of an aliphatic, aromatic, or mixed radical, an oxyalkylamine, an amino acid, a heterocyclic base or a derivative thereof.  Cotton yarn or linters, wood pulp, regenerated cellulose in the form of artificial silk, staple fibre, or films, also mercerized cellulose from cotton or wood pulp, may be used as parent material. Caustic soda or potash solution may be employed as alkali and the concentration may be low or of mercerizing strength.  The epichlorhydrin and ammonia or ammonia derivative may be employed in vapour form or in solution, e.g. in benzene.  The ammonia or derivative may be incorporated with the alkali lye with which the cellulose material is treated.  The products retain the fibrous or other form of the parent material.  They may be dyed with acid wool dyestuffs.  In an example, alkali cellulose from sulphite cellulose is spread in a thin layer and subjected to the action of liquid ammonia and epichlorhydrin.  The product is washed with dilute acid and water.  Cotton linters or mercerized sulphite cellulose are immersed in caustic soda solution containing hydroxyethylamine, the sodium salt of glycocoll, or anthranilic acid.  The pressed material is subjected to epichlorhydrin liquid or vapour in a vacuum.  Viscose staple fibre is treated with caustic potash and subjected to the vapours of ammonia and epichlorhydrin in a vacuum.  Cotton hanks are treated with caustic soda and then with liquid ammonia and epichlorhydrin.  Viscose staple fibre is treated with caustic potash, centrifuged, subjected to ammonia vapour in a vacuum, cooled, and treated with a solution of epichlorhydrin in benzene or carbon tetrachloride.  The products contain 0,2--2,7 per cent of nitrogen.

Title: Apparatus for rendering to powder cereal grains by abrasion
IPC: B02C9/00
Filed: 1946-07-19
Abstract: 640,561. Treating grain. HAMES, H. July 19, 1946, No. 21600. Convention date, July 26, 1945. [Class 58] An apparatus for rendering to pow- 'der cereal grains, particularly for opening the cells of the proteinlayer of these grains to extract the nutritive substances contained therein, but suitable also for the complete reduction of the grains to powder, comprises concentrically disposed abrasive surfaces 6 constituting cells through which, with the aid of guides 7, the materials are caused to travel from one lateral end of the apparatus to the other, following opposite directions in successive cells and moving in a radial direction from the centre to the periphery, or vice versa, across the apparatus, while simultaneously subjecting these materials to the action of an induced sweeping gaseous current particularly of air, flowing through each of these cells from one end of the apparatus to the other. As shown in Fig. 1, a series of concentric abrasive partitions 6 forming cells between them has an abrasive helical guide 7 of height preferably less than the distance between the partitions which determines a helical path extending from one lateral end to the other of the partition, while providing for a free passage uniting these two ends. Grain is fed through the port 10 on to the partition 6 which follows immediately radially outwards the innermost partition and is abraded as the partition revolves with the shaft 3. At the end of the grain receiving partition opposite the feeding end the grains fall in the next partition in radially outward direction and are moved in the opposite direction by means of the guide 7, and at the end of the partition the process is repeated. The powdered products from each cell are withdrawn by suction applied at the discharge 13 and the residual matter is evacuated by the pipe 12. In a modification. Fig. 5, the material travels radially from the periphery to the centre. The feeding pipe 10 is arranged so that the material is fed on the partition, which follows from the periphery towards the centre, the outermost partition, through a cut-away portion of this latter, the pipe 10 passing through the fixed cover 8 and opening above said partition. The discharge 12 in the lower portion of the apparatus is extended towards the centre but situated laterally outside that occupied by the partions 6. These are provided' alternately at the opposite lateral ends thereof, with spiral-shaped guides 17 connecting one cell with the next inner cell, the innermost of these guides opening out into a cone 18 which discharges primarily into the outlet 12. In each modification the apparatus may be operated so that the grains simply slide or roll on the partitions or are carried thereby so that a turbulent state of grains occurs locally in the cells.

Abstract: 391,788. Rollers. DU PONT VISCOLOID CO., 7, West 10th Street, Wilmington, Delaware, U.S.A. July 29, 1931, No. 21679. Convention date, Aug. 8, 1930. Drawings to Specification. [Class 42 (ii).] A roller for contacting with textile fibres in fly frames, drawing frames &c., comprises a contacting surface of a substantially non-inflammable carbo-hydrate compound, such as cellulose actate or other non-inflammable cellulose ester or ether or ester of starch, together with a plasticizer. A suitable preparation comprises 75 parts of cellulose acetate, 15 parts of dibutyl phthalate, and 10 parts of dimethyl phthalate, but other plasticizers such as an aromatic ester as triphenyl phosphate, also triacetin, ethyl paratoluene sulphonamide, acetanilide, and methyl or ethyl acetanilide are instanced. The roller is formed with a metallic core and may have a felt or other cot disposed between the core and the covering. In forming the roller, a tube of " plastic " may be extruded over the core and be shrunk thereon, or a preformed tube may be softened and stretched to adapt it to be slipped over the core, the slipping being effected by first placing the tube over a thin metallic cylinder which is then passed over the core ; on removal of the cylinder, the drying of the tube shrinks it on to the core. Alternatively, uncompacted plastic sheet is rolled around the core or the " plastic " is applied as a dope by spraying, dipping or brushing. The dried roller is trued by grinding. The thickness of the covering and its hardness may be varied, a thick soft covering being used in the absence of a cot. The covering may be applied as a varnish to the outside of ordinary leather-covered rollers. Specification 349,990, [Group IX], is referred to.

Abstract: 187,077. Rickman, W. G. Aug. 16, 1921. Enlarging, copying, and reducing; exposuremeters.-An indicator which is automatically operated on extending the camera is provided to indicate data which alter with the extension of the lens beyond the infinity point or stop, as, for example, the reduced F-value of the lens aperture, the change of exposure required, the degree of enlargement or other data. The indicator may consist of a pointer rotating with relation to a fixed disc as in Fig. 6, or of a disc rotating behind a slot as in Fig. 26, or of a blind or a simple roller moving behind a slot as in Fig. 37. The mechanism for rotating the disc or pointer comprises a cord &c. G secured adjustably to the bellows by an adjustable drum S, Fig. 2, adapted when the bellows is extended to rotate a drum F, Fig. 8, round which it is wound against the action of a spring enclosed in the drum. This motion is transmitted through cogs E, C, to a dial H, of which the markings are visible through a slot A<2> in the lid of the indicator container A. In this form a second indicator disc K may be mounted on the outside of the indicator case A on a boss J, Fig. 28, the boss carrying also an adjustable pointer L<2> with reference to which the inner indicator disc H rotates. The zero or normal mark on this inner disc acts as a moving pointer for the outer indicator disc. A magnifying lens L<1> may be secured in the boss J to facilitate the reading of the inner indicator. The external indicator may be used alone, in which case the inner indicator is replaced by a pointer. The roller blind indicator, shown in Fig. 37, is operated similarly by a drum F and cogs E, C, and is arranged to have its zero adjustable by moving the cog C out of engagement with the cog E against the action of spring Q. The roller indicator is arranged as shown in Fig. 38. Various arrangements of the lens data on the indicators are shown on the drawings, and the camera may be provided with a number of interchangeable indicators corresponding to lenses of different focal lengths, the data shown being the F ratios, the various degrees of enlargement or reduction, the positions of conjugate focus, and the duration of exposure compared with that for a like aperture at infinity point or with that necessary for copying full size.
