Title: Method and apparatus for the moulding of cellular material
IPC: E03D1/08
Filed: 1963-02-04
Abstract: 1,014,502. Moulding foamed plastics articles. PNEUMATIQUES CAOUTHOUC MANUFACTURE ET PLASTIQUES KLEBER COLOMBES. Feb. 4, 1963 [Feb. 5, 1962], No. 4450/63. Heading B5A. A method for the manufacture of a shaped object in cellular material comprises subjecting said material to an expansion operation in a liquid bath, wherein said material is held immersed in the liquid in contact with a downward facing moulding surface and against which hydrostatic thrust of said liquid presses said material so as to mould it against the surface into the desired shape. The lower surface of the cellular material may also be pressed against a moulding surface at least toward the end of the expansion period. Pairs of such moulding surfaces may be spring loaded or otherwise adjustable to facilitate removal of the shaped objects therebetween or to modify the moulding effects thereof. The moulding surfaces may be planar or curved and may be perforated plates or grids. In Fig. 1, a heat-insulated vessel 1 contains water 2 heated by a steam pipe 3 and has a lid 9 containing water or other substance to act as ballast and heat-insulator. Cellular bodies of original size 13 are expanded below the shelves 8 1 , 8 2  &c. The gauge 4 allows the degree of expansion to be controlled by observing the rise in water level. Pump 5 allows stirring and removal of water. The process may be employed for the expansion and moulding in a water bath of polyvinylchloride based embryonic cellular objects containing an organic isocyanate.

Abstract: 1,144,721. Endless conveyers. MILLARS MACHINERY CO. Ltd. 3 Jan., 1967 [1 Feb., 1966], No. 4453/66. Heading B8A. The feed hopper 1 of an endless belt 8 has a bottom opening which is closed by the belt and is of divergent shape (in plan view, as shown) in the direction of conveyance. The downstream end of the hopper is open except for an upper zone covered by a plate 12 which is adjustably slidable as provided by slots (15) (Figs. 1 and 4, not shown) and a clamp rod 16. There is a seal between the lower edges of the sides and back of the hopper, and the belt. A plate 43 pivotally mounted at 42 rests on the bed of conveyed material and operates a microswitch (46) to stop the conveyer or when the material flow ceases. Alternatively the switch (46) may furnish an indication of a given depth of material. A storage hopper (49) may feed the hopper 1 via an isolating flat plate type of valve. The drive of the belt 8 may be of the intermittent kind described in Specification 655,703.

Title: Process for concurrently treating process waste waters and flue gases from ammonia synthesis
IPC: C02F1/20
Filed: 1975-02-03
Abstract: 1480657 Treatment of waste water and flue gas SUMITOMO CHEMICAL CO Ltd 3 Feb 1975 [11 April 1974] 4574/75 Headings C1A and ClC Waste water containing ammoniacal nitrogen and organic materials and flue gases containing NO x  discharged from an ammonia synthesis gas manufacturing plant in which hydrocarbons are reformed with steam are treated to render them innocuous by removing the ammoniacal nitrogen and the organic material in gaseous form from the waste water, selectively decomposing the organic material in the presence of a catalyst at a temperature of 120-400 C., mixing the resulting gases with the flue gases so that the mixture contains NH 3  in an amount of 0À3-10 moles per mole of NO x  and effecting the reduction of the NO + by bringing the mixture into contact with a second catalyst at a temperature of 150-700 C. Any NH 3  remaining may be removed by oxidizing the product gases in the presence of a third catalyst. The waste water may be stripped with superheated steam, hot air or a portion of the flue gases and the gases formed are passed at a space velocity of 500-50,000 hr<SP>-1</SP> over a catalyst which may be iron, nickel, chromium, zinc or copper or oxides or complex oxides thereof. If O 2  is a component of the mixture, the reaction is carried out at 120-250 C. whereas if O 2  is absent the reaction is preferably carried out at 150-400 C. The gases are then mixed with flue gases, further NH 3  being added if necessary to achieve the required molar ratio which is preferably between 0À7 and 5 moles per mole of NO x . The gases are preferably passed at rate of 2,000- 100,000 hr<SP>-1</SP> and a temperature of 150-500 C. over a second catalyst which may be a noble metal, e.g. Pt, Pd, a metal oxide, e.g. of Cu, V, Mo or W or a complex metal oxide such as an Fe-Cr, CuCr, or a Mn-Cr. Preferred catalysts are complex oxides containing V and one or more of Cu, Zn, Sn, Pb, Ti, P, Cr, Co, Ni, W or Mo or containing Cr and one or more of Ni, Co, Zn, Mo, W, Sn, P or Ti. If the gases contain excess ammonia, they are preferably passed at a rate of 2,000-100,000 hr<SP>-1</SP> and a temperature of 150-700 C. over a catalyst which is a chromium oxide, a complex oxide of Cr with Fe, Mg or one or more of Sn, Sb, V, Co, P, Zn, Ni, Pi, Mo or W.

Class 100(1) [Also in Group XX] In a magazine for simultaneously winding on and unwinding an endless film,. wherein the film, with its width vertically disposed, is coiled in a number of layers about at least two spaced cores having. their bases located in the same plane and is pulled off the inner-most layer, at least' two of the cores are provided with a flange projecting from the base surface thereof, the flange having a film-supporting surface in the form of a truncated cone with the apex thereof directed upwardly and located in the axis of rotation of the core. Two spools 3, rotatable on a plate 1, have cylindrical cores 6 each having a central groove 7 providing edges 8. A flange 9 projects from one of the edges 8 of each spool, the inner surface of the flange 9 being inclined, such that the flange forms a truncated cone having its apex on the axis of a spindle 4 mounted in bearings 5. The conical surfaces cause the film layers to slide apart outwardly in a radial direction thereby reducing friction between the layers. The inside of the flange 9 may have oblique ridges to reduce the contact surface between film, wound around the cores, and the flanges 9. A roller 12 is disposed between the spools to guide an endless film from the inner convolution around the spools 3, to a film projector, while a similar roller 14 guides the film to the outer convolution. In a modification, Figs. 3 and 4, not shown, the axes of the cores and flanges are arranged in a circle and are spaced apart by 90 degrees in an annular holder having film-engaging guide rollers between the cores.

Title: Process for removing mercaptans from hydrocarbon fractions
IPC: C10G29/24
Filed: 1953-02-24
Abstract: Mercaptans are removed from hydrocarbon fractions by contacting the fractions with minor proportions of an aliphatic or aromatic aldehyde, a primary or secondary aliphatic amine and an anhydrous salt that absorbs water under the reaction conditions, so that a complex is formed between the mercaptans, the aldehyde and the amine, and then separating the complex from the purified fractions. Hydrocarbon fractions mentioned are petroleum distillates such as naphtha, gasoline, kerosene and gas oil and hydrocarbon fractions used as extraction agents in the extraction of edible oils or fats or of natural perfume oils.  The aldehyde may be formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde or acrolein, but the 30 per cent aqueous formaldehyde solution known as formalin is preferred.  The amine may be an alkanolamine such as mono- or diethanolamine, or a diamine such as ethylene diamine, while the preferred anhydrous salt is anhydrous sodium or potassium carbonate.  In the case where formaldehyde and an amine R.NH2 are employed, these react with the mercaptan R1.SH with the elimination of water to form the complex R.NH.CH2.SR1.  In the examples, petroleum spirits are stirred with a mixture of formalin, anhydrous potassium carbonate and ethylene diamine, mono- or diethanolamine or diethylamine at room temperature or a little higher, successive treatments with fresh reagents being used in some cases.  The refined spirits are decanted, washed with water and distilled.  Specification 700,165 is referred to.
