| 61 | ONE-PIECE MANUFACTURING PROCESS | PCT/US2010055081 | 2010-11-02 | WO2011056780A3 | 2011-08-04 | PICKRELL KEVIN; KUZDZAL MARK J |
| A method of making a turbomachine part, wherein the method can include machining a blank into a base having blades extending therefrom, the blades defining a channel therebetween. The method can also include forming a bridge in the channel between the blades, and forming a cover on the tops of the blades and over the channel, such that the base, the blades, and the cover form a single substantially homogenous turbomachine part once the bridge is removed. | ||||||
| 62 | Polyurethane casting compound for producing wear protection coatings in casting house applications | US14430050 | 2013-10-01 | US09738749B2 | 2017-08-22 | Wolfgang Dürnay; Florian Gneiting |
| The present invention relates to multi-component compositions including an isocyanate component and an amine component, wherein the isocyanate component includes a prepolymer, obtainable from toluene isocyanate and a polytetramethylene polyol, and the amine component includes a dialkylthio aryl diamine and possibly a polytetramethylene oxide polyamine. Corresponding compositions can be advantageously used as flowable or spreadable resin systems for producing surface protection coatings in casting house applications and are characterized by a significantly improved resistance to abrasion in comparison with conventional casting resin systems based on hexamethylene diisocyanate and dimethyl thiotoluene diamine. | ||||||

| A method for manufacturing a bolster of a railway car truck includes providing a drag portion and a cope portion of a mold. In a main body section of the mold, a parting line that separates the drag portion from the cope portion is substantially centered between portions of the mold that define brake window openings in sides of the bolster. One or more cores are inserted into the mold and a molten material is poured into the mold to thereby case the bolster. | ||||||

| 66 | Integral casting flask and vacuum chamber | US266581 | 1988-11-03 | US4915155A | 1990-04-10 | Richard A. Martin |
| An integral casting flask/vacuum chamber combination is disclosed in which an inner tube forming the casting flask is disposed coaxially inside of an outer tube thus forming a vacuum chamber between the two tubes. The inner tube has holes formed in its circumference to provide for uniform evacuation of air from the investment for pulling the casting material into the mold. A shoulder portion integrally connects the inner tube with the outer tube in such a way that the bottom edge of the inner tube is suspended above the bottom edge of the outer tube and the top edge of the inner tube is suspended above the top edge of the outer tube. This device is used in combination with a vacuum table and does not require the complex and expensive conventional vacuum chamber. | ||||||
| 67 | Foundry flask | US3766970D | 1971-11-01 | US3766970A | 1973-10-23 | HATCH E |
| A foundry flask which may find utility in machines which produce flaskless molds includes four walls with vertically extending pins interconnecting the walls at diagonally opposite corners, such pins including a tapered portion cooperating with tapered bushings on one of the adjoining walls so that vertical movement of the pins will separate the tapered portion and bushing, permitting resilient spacers to separate adjoining walls to facilitate removal of a mold from the flask.
