Title: Method of manufacturing a sintered body from powdered material
IPC: B22F3/12
Filed: 1972-03-14
Abstract: 1374033 Isostatic hot pressing ALLMNNA SVENSKA ELEKTRISKA AB 14 March 1972 [15 March 1971] 11739/72 Heading C7D Sintered bodies are made by coating the surface of a powder compact with a lower melting material or a material forming a eutectic with the powder body, heating under vacuum to melt the coating and then isostatically hot pressing the coated compact with an inert pressure gas e.g. A, He, N 2  or H 2 . The powder compact may be Mo, WC, TaC, TiC or VC and the coating material may be enamel or glass applied by flame or plasma spraying or immersion. In the case of Mo the coating may be Ni which forms a eutectic with Mo. The melting and hot pressing may be carried out in the same or separate furnaces and although it is preferable to allow the fused coating to solidify before hot pressing, in some cases hot pressing may be effected when the coating is still fluid.

Abstract: 769,750. Combustion apparatus. ESSO RESEARCH & ENGINEERING CO. April 26,1955 [May 27, 1954], No. 11986/55. Classes 51 (I) and 51 (2). In combustion apparatus utilizing the " fluidized bed" technique and comprising a combustion vessel with a gas entry conduit protruding upwardly through the bottom thereof, a gas distributor capping the conduit has fitted thereto means for ensuring that gases issuing therefrom are discharged in a uniform pattern throughout the " bed." As shown in Fig. 1, coke from a fluidized coking vessel is fed to a vessel 1 through a duct 2 surmounted by a baffle 3. Heated coke is withdrawn from the vessel through a conduit 4, whilst a two-stage cyclone separator 8 cleans the hot gases emanating from the " bed," returning the solid particles entrained therein to the bed. Hot gas for combustion and fluidization is introduced into the bed via means 5, this comprising an auxiliary burner to which secondary combustion air, which may be diluted with steam, is fed through duct 6, which also supplies the necessary air for combustion in the " bed " If the air supply fails an inert fluidization gas may be introduced through duct 7. The hot gases from the means 5 pass downwards to the " bed ." through an annular passageway formed between a cylindrical skirt depending from a member 10 capping the upper outlet of the means 5 and the outer surface of the said means located within the vessel 1. The lower end of the passageway has a baffle such that the volume of gases passing from the passageway directly downwardly is limited, the bulk of the gases being directed by a baffle 15 disposed above the first-mentioned baffle into four pipes 14 each of which conducts gas to a pipe 16, Fig. 2, perforated for the purpose of passing gas to the " bed." As shown in Fig. 4, the lower end of the skirt depending from the member 10 is serrated and gases issuing from the annular passageway are distributed towards the walls of the vessel 1 by an annular flange 19 which has a downwardly depending serrated skirt 20.. The auxiliary burner shown in Fig. 4 comprises a refractory-lined combustion chamber 25 into which a gas or liquid fuel element 21 extends, primary combustion air being admitted through a duct 22. Specification 711,671 is referred to.

Abstract: 542,707. Making tyres. DUNLOP RUBBER CO., Ltd., and WILLSHAW, H. July 22, 1940, No. 11995. [Class 87 (ii)] [Also in Group XXXIV] Apparatus for withdrawing a segmental core from a built-up tyre cover comprises means for rotatably supporting the tyre and mechanism for extracting the core-segments. Means may also be provided for spreading the tyre beads and such means may be utilized to afford lateral support for the tyre-and-core assembly. As shown in Figs. 1 and 2, the tyre is supported on a pair of rollers 1, 2 arranged to be driven from a motor 11, loading-rollers 14 being adapted for movement on to and away from the upper run of the tyre by linkage 17, 19 to a power-cylinder 20 and its piston. Lateral support is provided by sets of side-rollers 15, 16. The core-segments 9 are mounted on a centre 10 which is forced out of the ring of segments, by a power-operated ram 22, to admit the extract ordevice shown in Fig. 3. This comprises a power-cylinder 30 slung from an overhead rail 29, the piston 31 being connected by linkage 33, 37, 38, 41 to a movable jaw 43 between which and a fixed jaw 36 on a lever 34, the base of a core-segment 9 is gripped. In operation, the upward movement of the piston 31 acting on the toggle 37; 38 first moves the jaw 43 into engagement with the core-segment, further movement of the piston, coupled with downward pressure by the operator on the lever-handle 35, levering the segment out of the tyre. Figs. 5 and 6 show a modification in which the rollers 1, 2, are driven by a handwheel 49 ; the lateral support is afforded by rollers 50 in the lower run only of the tyre; and bead-spreaders are provided. As shown, the latter consist of levers 52 with hooked ends 51 for engaging the tyre-beads, the levers being pivoted at 53 on brackets 54 adjustably secured to slides 55. Rollers 56 on the slides engage in fixed vertical guides 57. The lower ends of the levers 52 are fitted with rollers 62 which are constrained, by springs 64, to engage angled tracks 65, 66 on fixed cams 63 to give relative lateral movement to the hooks 51 in the up and down movements of the slides 55. For effecting the latter, the slides are carried by a yoke 59 which is secured at 60 to the plunger of a power-cylinder 61.

Title: A process for delustring lustrous fibrous materials
IPC: D06M13/282
Filed: 1935-04-18
Abstract: Lustrous fibrous materials particularly artificial silk, which have been darkly dyed are delustred by precipitating thereon substances giving rise to cations capable of reducing the surface tension together with tanning agents or dye-wood extracts and iron salts. The articles may be treated with a quaternary high molecular ammonium or phosphonium compound, a high molecular ternary sulphonium compound, asymmetric oleyl-diethyl-ethylene-diamine, substances known under the Registered Trade Mark "Sapamin," iso-urea or iso-thiourea substituted by high molecular organic residues, addition products of high molecular alkyl or aryl halogenides with hexamethylene tetramine, or high molecular alkyl or aryl guanidines, these substances all giving rise to cations which reduce the surface tension.  The goods may be saturated with a solution of one of these substances together with an iron salt, centrifuged or pressed and dried, and then treated with tanning material or dyewood extract. The iron salt may be omitted from the first bath and employed after the tanning bath.  The tanning agent or extract for black materials may be chestnut wood extract, valonia extract, sumach, and gall nut extract.  For green materials, gambier, fustic, or quebracho extract may be used.  For blue materials, logwood extract, and for red materials, redwood extract may be used.  Mixtures of these extracts or synthetic tanning materials may also be used.  The delustred materials may be treated with soap solution at raised temperature. In an example, hanks of black-dyed viscose artificial silk are treated with a warm solution of dodecyl pyridinium sulphate and ferric chloride.  They are wrung out and treated with a solution of chestnut wood extract, rinsed or soaped.  In another example, hanks of blue-dyed viscose artificial silk are treated with dodecyl pyridinium bromide and ferric chloride solution, wrung out, treated with logwood extract, and then heated with soap solution.

Filed: 1933-04-28
Abstract: Acetyl chloride is prepared by the interaction of liquid acetic acid and gaseous phosgene at a raised temperature and approximately normal pressure under conditions whereby the acetyl chloride produced is continuously removed by evaporation.  As catalysts for the reaction, use may be made of such compounds of metals of the second and third periodic groups as are soluble in hot acetic acid, e.g. magnesium oxide, anhydrous calcium chloride, or aluminium acetate.  Examples are given in which the reaction is effected at 80 or 110 DEG C. in a vessel connected to a condenser which returns any acetic anhydride formed to the vessel, the acetyl chloride and the gaseous reaction products passing from the condenser to a refrigerator, and fresh acetic acid being continuously run into the vessel; the phosgene may be passed in through a porous plate in the vessel, and the gaseous reaction products undergoing cooling may be washed with a liquid which absorbs acetyl chloride without absorbing much hydrogen chloride; suitable washing liquids are mixtures of acetic acid and acetic anhydride and also hydrocarbons and their halogen- or nitro-derivatives, such as chloronaphthalene.
