Title: The liquid calcium nitrate fertilizer and the process for obtaining it
Inventor: TATARISKINAITE LINA
IPC: C05C5/00
Filed: 2008-08-13
Abstract: The present invention relates to production of liquid fertilizer and can be used for production of the liquid calcium nitrate fertilizer. The liquid calcium nitrate fertilizer are obtained from 30-57 % nitric acid solution and caustic lime. The amount of calcium nitrate is 34-58,6 % and the nutritional components ratio is as follow (in mass percent):nitrogen 5,8-10, calcium 11,6-20, magnesium 0,5-2,0. The method of production comprises gradual decomposition of caustic lime with nitric acid, neutralization and standartisation of mixture obtained with caustic lime, precipitation and separation of calcium nitrate suspension from precipitate or filtration of suspension. Two products are obtained: liquid calcium nitrate fertilizer (suspension) for supplementary fertilization by spraying and liquid calcium nitrate fertilizer (after filtration) which meets the requirements for aquaculture and can be used for basic or supplementary fertilizing. A produced fertilizer contains more calcium and less nitrog

Title: Proceso de moldeado de piezas metalicas mediante esponja perdida y bajo presion
Inventor: GARAT MICHEL
IPC: B22D27/13
Filed: 1989-06-28
Abstract: La presente invención se refiere a proceso de vaciado en esponja perdida y bajo presión de piezas metálicas, que comprende las siguientes etapas: establecer un modelo de la pieza que se va a vaciar, formado de una esponja de materia orgánica revestida de una película refractaria; sumergir dicho modelo en un molde formado de arena seca sin elasticidad; llenar el molde con el metal en el estado fundido para calentar el modelo; evacuar los vapores y residuos líquidos emitidos por el modelo; permitir al metal fundido solidificarse para obtener dicha pieza; aplicar en el molde antes que la fracción solidificada de metal rebase el 40 por ciento en peso, una presión isostática de valor máximo comprendida entre 0.5 y 1.5 MPa; el proceso se caracteriza porque la presión aumenta con la velocidad en función de la granulometria de la arena y de la profundidad de la inmersión del modelo generada rápida y temporalmente por la perdida de carga a traves del nviel de su interfase, esta superpresión alcanza un valor comprendido entre los dos límites y decrece posteriormente a medida que la presión aumenta despues para mantener la presión constante hasta que se complete la solidificación.

Abstract: A high temperature PVC resin blend is made by blending from 60 to 85 parts PVC with no more than 40 parts of a ("alpha-SAN") copolymer of alpha-methyl styrene ("AMS"), styrene ("S") and acrylonitrile ("AN"), and less than 20 parts by wt additives including stabilizers, antioxidants, lubricants, and processing aids. In addition, an impact modifier may be added. The blend with particularly sized glass fibers, may be thermoformed at an elevated processing temperature and pressure, to provide a reinforced composite in which the PVC is covalently bonded to the glass fiber. The composite has a substantially higher HDT and equivalent tensile strength, compared to that of a similarly reinforced, unblended PVC composite, without sacrificing the novel composite's other desirable physical properties. The glass is sized with an aminosilane coupling agent, and, a polymer film former selected from the group consisting of (i) a polymer with a nitrogen-containing repeating unit such as an amine, amide, ureido, or urethane group, and (ii) a dispersible or emulsifiable epoxide polymer, which composite, upon extraction with THF, and a subsequent XPS examination, yields a Cl(2p)/C(ls) ratio of at least 0.91, and more preferably of at least 1.13. Glass fibers, thus sized, provide cohesive bonding of the resin, so the composite fails in cohesive failure. A unique sequence of mixing the blend ingredients with glass fiber provides optimum properties in the composite. The sequence requires formation of a single phase of PVC and alpha-SAN copolymer before dispersing the glass fibers in the blend.

Abstract: A process for the simultaneous manufacture of pure methyl tertiary butyl ether (MTBE) and a substantially isotubene-free mixture of C4-hydrocarbons, by reacting the isobutene contained in the mixture of C4-hydrocarbons with excess methanol in the liquid phase at elevated temperatures on strongly acid, macroporous, organic ion exchange resins. The process has the following steps: (a) methanol and isobutene are reacted in a molar ratio of 2:1 to 5:1 at temperatures between 30 DEG and 100 DEG C.; (b) the unconverted hydrocarbons are then removed as the top product under a pressure of 2 to 10 bars from a first rectification column; (c) the bottom product from this first column is rectified in a second column under normal pressure or under a slight excess pressure of up to 2 bars at the top of the column, the bottom product of this rectification is recycled to reaction zone (a), if necessary, after separating off a portion of the tertiary butanol formed and the C8-olefins; and (d) the distillate from this second column is rectified in a third rectification column under a pressure of 5 to 30 bars, the distillate thus obtained is recycled into the feed to the second column and pure methyl tertiary butyl ether is withdrawn from the bottom of the third column.

Abstract: The invention concerns procedure and an apparatus for the heat and humidity treatment of products, for example those made of concrete.The products are treated in a tunnel shaped chamber (4) by regulating the ambient temperature and humidity.  During a temperature increase stage, the products are subjected to an air stream with a temperature of 40-100 degrees C; the products are then subjected to a steam air mixture for 1-6 hours in a temperature increase zone (5), where the mixture's temperature and humidity are each increased gradually up to the allowed values, depending on the product.  In an isothermal holding zone (6), the products are subjected to a heat transfer medium with a temperature of 60-95 degrees C and a relative humidity close to 100 per cent for 2-6 hours, and in a cooling zone (7) the products are subjected to a flow of a cooling medium with a relative humidity of 35-90 per cent for 0.5 - 1.5 hours.  The apparatus includes a chamber (1) equipped with air ducts (20) for preparatory drying, from which every air duct (2) is connected to air screen collector (3) at the tunnel chamber's (4) entry side.The invention enables the reduction of treatment times for the products and improves their quality by lessening the concrete's deterioration.<IMAGE>

Title: Pipe cleansing, drying and pressure testing process
Inventor: FJELLSTROM BENGT
IPC: B08B9/02
Filed: 1982-01-05
Abstract: The process is for internal washing or cleansing, together with pressure testing, subsequent clean-blowing or drying of pipes (1) or hoses. It is used where the pipe requires to be cleansed of dirt and oil residue from an earlier machining process. The cleansing medium is circulated (6,5,4) through the pipe, and then final drying medium - preferably heated compressed air - is partly circulated. The pressure testing phase (18,14,17,4,2,1) takes place between the washing and blowing-clean phases. During pressure testing, the bending head (2) and pipe (1) are screened from the outer circuit using pilot-controlled check valves (15,16) and similarly controlled two-way valves (21). Pressure testing then takes place using a pressure increasing device (14), and the same fluid as is used for cleansing. (Provisional Basic advised week 83/34)

Title: Surface-water manhole with a water seal provided with a float
Inventor: LERKFELDT O
IPC: E03F5/04
Filed: 1982-04-28
Abstract: The present invention relates to a surface-water manhole of the type comprising a lower part 1 provided with a bottom 2 with a sand trap 6 and at least one side aperture 3 which is located above the sand trap and is intended for connection to a pipe 4. This aperture constitutes the spillway from the manhole to the pipe and, when the water levels in the manhole are lower than the level of the aperture itself, it is closed by a water seal in which a float 7 is included as a member for opening or closing the aperture 3 as a function of the water level. The characteristic of a surface-water manhole designed according to the invention is that the float 7 is tubular with its geometric axis directed in the direction of depth of the manhole, in which direction it has a greater extent that the side aperture 3 in the lower part 1 of the manhole, and it has an external shape and size matching the inside of the manhole, so that it can easily move up and down in a controlled manner in the manhole as a function of the water level present in the latter. <IMAGE>
