In one exemplary embodiment, an airfoil includes pressure and suction side walls that extend in a chord-wise direction between leading and trailing edges. The pressure and suction side walls also extend in a radial direction to provide an exterior airfoil surface. A cooling passage is arranged between the pressure and suction walls. The cooling passage has a first width in the chord-wise direction near the suction side wall. A second width is in the chord-wise direction near the pressure side wall. A third width is between the pressure and suction side walls. The third width is smaller than the first and second widths.

A method including modifying a known upper denture to form a final upper denture by a series of steps which may include making holes in a gums section made of a first material of the known upper denture, cutting away a palate section, and applying a gold and silicon mixture to make a new palate section, to insert into the holes in the gums section, and to cover the first material. The method may also include modifying a known lower denture to form a final lower denture by a series of steps which may include making holes in a gums section made of a first material of the known lower denture, and applying a gold and silicon mixture to insert into the holes, and to cover the first material. The first material may be nylon.

A green sand mold molding sensor that can measure the pressure applied to a parting plane of a green sand mold in order to determine the quality (casting mold strength) of a molded green sand mold. A green sand mold molding sensor including a pressure sensor for evaluating the molding properties of a green sand mold molded by a casting mold molding machine, wherein the pressure sensor is embedded in a plate having a model attached thereto.

Jewelry that includes a topographical feature of a selected geographic location is made by obtaining topographic data for a geographic area around the selected location. The data is then used to create a topographic surface that is representative of the topography of the area and the 3D surface is adjusted for scale, viewpoint, and other features and merged with a template for a piece of jewelry. The resulting merged object is printed and the printed object is cast to produce a piece of jewelry that includes a topographic representation of the selected location.

A moulded part (1) for a mould (100). The moulded part (1) comprises at least one shell (11) for casting a product. A flange (12) is arranged on a frame of the moulded part (1) for sealing against abutment a sealing surface (13). The shell (11) has a first permeability for a fluid and the flange (12) has a second permeability for the fluid. The second permeability is less than the first permeability.

The invention relates to a high-strength copper-nickel-tin alloy with excellent castability, hot workability and cold workability, high resistance to abrasive wear, adhesive wear and fretting wear and improved resistance to corrosion and stress relaxation stability, consisting of (in weight %): 2.0-10.0% Ni, 2.0-10.0% Sn, 0.01-1.5% Si, 0.01-1.0% Fe, 0.002-0.45% B, 0.001-0.15% P, selectively up to a maximum of 2.0% Co, optionally also up to a maximum 2.0% Zn, selectively up to a maximum of0.25% Pb, the residue being copper and unavoidable impurities, characterised in thatthe ratio Si/B of the element contents in wt. % of the elements silicon and boron is a minimum 0.4 and a maximum 8; such that the copper-nickel-tin alloy has Si-containing and B-containing phases and phases of the systems NiSiB, NiB, FeB, NiP, FeP, NiSi and other Fe-containing phases which significantly improve the processing properties and use properties of the alloy. The invention also relates to a casting variant and a further-processed variant of the high-strength copper-nickel-tin alloy, to a production method, and to the use of the alloy.

An inspection device is a device that inspects the appearance of a target, including: an imaging device configured to image the target from a first direction; an illuminating unit configured to apply light to the target; and a controller configured to acquire a first inspection image by causing the imaging device to image the target to which light is applied from a first position, to acquire a second inspection image by causing the imaging device to image the target to which light is applied from a second position, and to inspect an appearance of the target based on the first inspection image, the second inspection image, and a reference image. The first position and the second position overlap each other when viewed from the first direction.

A method for fabrication includes providing a substrate having an upper surface with pattern of one or more recesses formed therein. A laser beam is directed to impinge on a donor film so as to eject droplets of a fluid from the donor film by laser-induced forward transfer (LIFT) into the one or more recesses. The fluid hardens within the one or more recesses to form a solid piece having a shape defined by the one or more recesses. The substrate is removed from the solid piece. In some embodiments, the recesses are coated with a thin-film layer before ejecting the droplets into the recesses, such that the thin-film layer remains as an outer surface of the solid piece after removing the substrate.

A method of providing a tool with a conformal cooling passage includes rough machining a cavity generally corresponding to a manufactured part shape using CAD data. Conformal cooling slots are cut in the cavity using the CAD data. The conformal cooling slots are welded shut using the CAD data to provide conformal cooling passages. A class A surface is machined over the conformal cooling passage and corresponds to a finished manufactured part shape using the CAD data.
