Title: Manufacture of artificial products from cellulose derivatives
IPC: C08B11/08
Filed: 1928-02-13
Abstract: 285,355. I. G. Farbenindustrie Akt.- Ges. Feb. 12, 1927, [Convention date]. Adhesives; sizes. - Agglutinants, sizes, dressings, coatings, &c. are prepared by the elimination of the organic solvent and water from emulsions which consist on the one hand of solutions in organic solvents of cellulose derivatives insoluble in water and on the other hand of cellulose derivatives dissolved in or swollen bv water. Suitable water-soluble derivatives are cellulose ethers, particularly methyl-celluloses containing 1.5-2.5 methoxyl groups, or ethylcelluloses containing not more than 1.5 ethoxyl groups, or water-soluble oxyalkyl cellulose ethers as obtained by the action of an alkylene oxide on cellulose or an alkylene chlorhydrin on soda cellulose. The water-insoluble derivatives may be nitrocelluloses, acetylcelluloses and other organic acid esters, and water-insoluble cellulose ethers. The emulsions are formed by mixing together the solutions in question; and the products are obtained by evaporation of the solvent at ordinary or elevated temperatures, with or without applying a vacuum. There may be incorporated with the solutions or with the emulsions, plasticizers, softening-agents, pigments, dyes, agglutinants, perfumes, filling materials, &c. In examples, a celluloid solution prepared with acetyl-glycollic acid ethyl ester, butyl acetate, butyl alcohol, xylene and light benzene, is emulsified with an aqueous solution of methyl cellulose, and the emulsion is used, if desired after the incorporation of a colouring matter, filler, &c., for the coating of cardboard; a solution of nitrocellulose in butyl acetate, butyl alcohol and benzene, is mixed with an aqueous solution of methyl cellulose, and the emulsion, with or without the addition of pigment, filler, &c., applied to a paper or fabric by means of rollers or printing blocks. The Specification as open to inspection under Sect. 91 (3) (a) refers to the elimination of the solvent with the aid of precipitating-baths; and it also includes the following example :-A solution of benzyl cellulose in benzyl alcohol, acetylglycollic acid ethyl ester, butyl alcohol, xylene and solvent naphtha, is emulsified with an aqueous solution of oxyethylcellulose, and the product used for waterproofing fabrics, or if the emulsion is applied repeatedly a completely-filled material is obtained suitable for use as drum-skins &c. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in high pressure apparatus
IPC: B01J3/06
Filed: 1956-02-14
Abstract: <PICT:0830209/III/1> <PICT:0830209/III/2> High-pressure apparatus comprises a pair of opposed recessed pistons; means for exerting pressure against at least one of the pistons; a die positioned partly within the recess in each piston, each die being provided with an annular lip surrounding a central recess; a reaction vessel located within the recesses of opposing die faces; and an annular insulating and pressure-resisting gasket surrounding the reaction vessel, the gasket tapering laterally and being arranged to have its outer edge fit between and be engaged by the lips of the dies.  Fig. 2 shows part of one arrangement wherein each die 18 is surrounded by a number of binding rings 19 (of which only one is shown) and is provided with a central recess surrounded by an annular lip 23.  The recesses are filled with blocks of insulating material 24 and by a reaction vessel comprising a hollow conductive cylinder 27 arranged between conductive end discs 26 and surrounded by an insulating washer 29. The reaction vessel is surrounded by a thermal and electrical insulating washer 30 which is tapered so that its outer edge fits between and engages the lips 23.  In operation pressure is applied to the dies by the pistons of an hydraulic press and at the same time an electric current is passed through the reaction chamber via the dies; thus a pressure of 35,000 atmospheres at a temperature higher than 2500 DEG  C. may be maintained in the reaction vessel.  Still higher pressures may be obtained if the washer 30 is surrounded by a compressible insulating gasket 31, Fig. 3, which may be of rubber or plastic and is held in place by soft steel retaining rings 32, 33. In a further arrangement, Fig. 4 (not shown), the apparatus is similar to that of Fig. 2 except that the washer 30 is divided into two halves with a metal washer arranged between the two halves.

Title: Improvements relating to materials suitable for use as fillers for rubber and other compositions
IPC: C01B31/08
Filed: 1942-04-08
Abstract: A reinforcing filler for compounding rubber, synthetic resins, &c. is obtained by mixing pitch with an inorganic material, e.g. magnesia, magnesium silicate or carbonate, aluminium silicate or alumina finely divided to pass through a sieve having 50 meshes to the linear inch and having a total surface area sufficient to absorb the agglutinating compounds of the pitch and heating the mixture to 550-1000 DEG  C. to yield a non-agglutinated friable residue.  The inorganic material may be extracted from the product to leave the carbon by leaching with acids &c.  When a magnesium compound is used, magnesium carbonate may be recovered by carbonating the product to covert the magnesia into magnesium bicarbonate and boiling the bicarbonate to produce a basic magnesium carbonate suspension. Magnesium hydroxide slurry from a tank 1 and ground pitch from a hopper 2 are mixed in a mixer 3 and passed through a drier 4 and pulverizer 5 to a furnace 6 heated to 700 DEG  C.  The vapours <PICT:0572860/IV/1> formed are recovered in a condenser 7, the residue may be further treated by addition of water in a carbonator 8 to which carbon dioxide is fed through line 10 and the solution of bicarbonate obtained is fed through a filter 12 to a boiling pan 16 from which the carbonate is recovered through a filter 18 and drier 19. Alternatively, the residue from the furnace may be subjected to acid extraction in an extractor 13 and activated carbon recovered through a filter 14 and washer 15.  Reference is made to Industrial and Engineering Chemistry, Vol. 26, p. 798, to Specification 18040/00, [Class 90], and to U.S.A. Specification 1,756,234.

Title: Improvements in and relating to the recording and reproducing of sound and other vibratory motion
IPC: G11B7/00
Filed: 1929-02-13
Abstract: 329,320. Irvine, M. M. Feb. 13, 1929. Photographic recorders.-Relates to apparatus for photographically recording sound or other vibrations'. According to the invention, light is transmitted to a recording film through two compigmentary graticules, the image of one of which is focused on the other and the passage of light through the graticules is controlled in accordance with the change of the size of the image of the one on the other. In the apparatus shown in Fig. 1, two graticules 7<a>, 9<a> are provided, each consisting of a translucent diaphragm 7 or 9 having a spiral line photographically produced thereon. The graticules are complementary, in the sense that one is the photographic negative of the other. The diaphragm 9 is fixed, whilst the diaphragm 7 is adapted to be vibrated by the sound or the like to be recorded. For this purpose it may, as shown, be connected to the armature 17 of an electromagnet 16 to which sound-controlled currents are transmitted. The armature is so pivoted at 18 that the diaphragm 7 can rock in the direction of the light beam. Light from a lamp 6 is concentrated on the graticule 7a, an image of which is focused on the graticule 9<a> by a lens 8. The intensity of light passing through both graticules varies in accordance with the vibrations of the member 7, and a record is made by allowing the transmitted beam to pass through a slit 10 on to a film 11, an optical system 13, 14 being preferably employed. Various alternative constructions and arrangements of the graticules are described. For example, as shown in Fig. 2, a diaphragm 19, suspended so that it can be vibrated by the direct action of sound, may be used, the graticule formed thereon consisting in this case of minute opaque and translucent squares. Fig. 5 shows another alternative, in which the graticules 31, 32 are formed as parallel gratings, the movable one 31 being vibrated by attachment to the bent armature 33 of an electromagnet 34. The armature is pivotally mounted in a fixed rubber sleeve. A further modification, Fig. 4, consists in using as the vibratory member a diaphragm-graticule constructed as described in Specification 329,328, [Class 40 (ii), Phonographs &c.]. An electrically conducting spiral 25 is deposited on either side of an insulating diaphragm 26 which is suspended in a magnetic field. Oscillating currents are passed either through the spirals 25, or through the magnet coil 30, or through both. A circular permanent magnet, within which the diaphagm is supported by threads, may be used instead of the magnet 28 shown in Fig. 4. Instead of fixing one graticule, both may be moved, either by the same mechanism or separately. Or both may be fixed, and the focusing lens adapted to move.
