20140165684 | SELF-COMPENSATING RETRACTABLE INSERT FOR HIGH-TEMPERATURE FORMING TOOLS - A forming tool apparatus is provided for forming an article having a negative draft angle that locks the formed article within the forming tool. An insert, which is disposed within a recess defined in a forming surface of the forming tool, has a surface that cooperates with the forming surface of the forming tool to shape a metal blank into a desired final shape. In particular, the surface of the insert is shaped to define the negative draft angle feature of the formed article. Subsequent to forming the article, a linear-drive mechanism is activated to withdraw the insert away from the formed article, and thereby unlock the formed article from the tool. The formed article is then extracted from the tool along an extraction direction that is other than parallel to the direction along which the insert is driven. | 06-19-2014 |
20140246129 | PRODUCT AND PROCESS BY LOCALIZED HEAT TREATMENT OF SHEET STEEL - A process for localized hardening of steel sheet components includes scanning a laser beam in a scan direction across a predetermined portion of the steel sheet component. The laser beam selectively heats material within the predetermined portion of the steel sheet component to a temperature of austenitizing transformation. During scanning of the laser beam across the predetermined portion, a source of external cooling is applied to the material within the predetermined portion and immediately behind the laser beam along the scan direction of the laser beam. The source of external cooling is selected to cool the material at a sufficiently rapid rate to form a locally hardened region that is defined substantially within the predetermined portion. Subsequent to applying the source of external cooling, the material within the predetermined portion of the steel sheet component is allowed to cool to ambient temperature. | 09-04-2014 |
20140339742 | METHOD FOR DIRECT INLINE MOLDING OF PRE-IMPREGNATED COMPOSITES - A system for fabricating a composite article includes a pre-impregnation station for forming a prepreg comprising a reinforcement impregnated with a resin. The prepreg is provided to a blanking station where a blank is cut from the partially cured prepreg and arranged onto a preforming mold. The blank is then transferred to a forming station, and is formed into the composite article using a compression mold. The pre-impregnation station, the blanking station and the forming station are co-located. During forming of the blank into the composite article using the compression mold, additional prepreg is formed in the pre-impregnation station and passes to the blanking station so as to form a next blank for being formed into a next composite article during a subsequent molding cycle. Optionally, the prepreg is partially cured prior to being cut in the blanking station. | 11-20-2014 |
20140342630 | WOVEN FABRIC PREFORMS AND PROCESS FOR MAKING THE SAME - Warps of a reinforcing filamentary yarn are selectively interwoven with wefts of the reinforcing filamentary yarn, so as to form a tailored woven reinforcement for use in the manufacture of a composite article having a known three-dimensional shape. The wefts extend in a direction transverse to said warps, to form at least one first portion of the woven reinforcement having interwoven warps and wefts, and to form at least one second portion of the woven reinforcement having other than interwoven warps and wefts. The at least one first portion and the at least one second portion are arranged, one relative to the other within said woven reinforcement, in dependence upon the known three-dimensional shape of the composite article. The woven reinforcement is suitable for use in a variety of processes including prepreg processes, Resin Transfer Molding processes and Resin Infusion Molding processes. | 11-20-2014 |
20150089992 | Process for Laser-Assisted Tool Build and Repair - A tool for forming a shaped product has a support body that is fabricated from a first material, such as for instance cast iron. The first material defines a first portion of a forming surface of the tool and has a feature supported thereon. The feature has a layer of a second material that is supported on the first material of the support body, a layer of a third material that is supported on the layer of the second material and a layer of a fourth material that is supported on the layer of the third material. The layer of the fourth material, such as for instance a tool steel alloy, defines a second portion of the forming surface of the tool. During use the first portion of the forming surface and the second portion of the forming surface cooperate to form a desired shape of the shaped product. | 04-02-2015 |

20080287593 | Amphiphilic Polymer Compositions and their Use - The present invention relates to amphiphilic polymer compositions, to a process for their preparation and to their use for preparing aqueous active compound compositions of water-insoluble active compounds, in particular active compounds for crop protection. | 11-20-2008 |
20100043672 | METHOD OF FINISHING ORGANIC PIGMENTS - The invention relates to a method of finishing an organic pigment that involves dissolving or dispersing the pigment in an aqueous solvent or a mineral acid and crystallizing the pigment from the solution or dispersion in the presence of a crystallization modifier, and subsequently isolating the pigment as a solid, wherein the crystallization modifier is a condensation product containing sulfonate groups and formed from at least one hydroxyarylsulfonic acid and/or at least one hydroxydiaryl sulfone compound and at least one aliphatic aldehyde having 1-6 C atoms, optionally urea, and an alkali metal sulfite if appropriate, or is a mixture of such condensation products. | 02-25-2010 |
20100050904 | PRODUCTION OF FINELY DIVIDED PIGMENTS - The invention relates to a methods finishing an organic pigment by dissolving or dispersing the pigment in a mineral acid and crystallizing the pigment from the solution or dispersion by mixing with an aqueous diluent in the presence of a crystallization modifier constituted by a sulfonate-functional condensation product of a naphthalenesulfonic acid and at least one aliphatic aldehyde having 1 to 6 carbon atoms, and then isolating the pigment as a solid, wherein the crystallization modifier is present in the aqueous diluent. | 03-04-2010 |
20100286445 | METHOD OF FINISHING ORGANIC PIGMENTS - A method of finishing an organic pigment that involves dissolving or dispersing the pigment in a mineral acid and crystallizing the pigment from the solution or dispersion by mixing with an aqueous diluent in the absence of a sulfonato-functional condensation product of an arylsulfonic acid and an aliphatic aldehyde as crystallization inhibitor, which comprises ripening the crystallized organic pigment in the presence of a surfactant or in the presence of a pigment solubility enhancer in aqueous suspension. | 11-11-2010 |
20110226160 | METHOD OF FINISHING ORGANIC PIGMENTS - A method of finishing an organic pigment by dry-comminuting said pigment in the presence of a sulfonato-functional condensation product of an arylsulfonic acid and at least one aliphatic aldehyde having 1 to 6 C atoms as crystallization modifier, dispersing the resulting mixture of pigment and crystallization modifier in mineral acid, and swelling the pigment in the presence of the crystallization modifier in mineral acid. | 09-22-2011 |
