  • Patent number: 9421660
    Abstract: A polishing method for machining an optical surface of an optical lens uses a polishing wheel which has a wheel axis and a polishing face. The polishing wheel is moved in relation to the lens over the surface of the latter along a spiral machining path. The polishing wheel is rotated about the wheel axis, and is (simultaneously) rotated about an axis of rotation oriented perpendicularly to the wheel axis. The rotational speed of the polishing wheel about the wheel axis and/or the axis of rotation is reduced at the spiral center of the movement path. A workpiece fixture for receiving an optical lens stands opposite the polishing wheel, with the workpiece fixture and the polishing wheel being mounted movably in relation to one another along a spiral movement path. The rotational speed of the wheel axis can be coupled kinematically to the rotational speed of the axis of rotation.

  • Patent number: 8914976
    Abstract: Bi-casting a platform (50) onto an end portion (42) of a turbine airfoil (31) after forming a coating of a fugitive material (56) on the end portion. After bi-casting the platform, the coating is dissolved and removed to relieve differential thermal shrinkage stress between the airfoil and platform. The thickness of the coating is varied around the end portion in proportion to varying amounts of local differential process shrinkage. The coating may be sprayed (76A, 76B) onto the end portion in opposite directions parallel to a chord line (41) of the airfoil or parallel to a mid-platform length (80) of the platform to form respective layers tapering in thickness from the leading (32) and trailing (34) edges along the suction side (36) of the airfoil.

    Abstract: The fastener stringer is arranged with at least one printable resin layer to which ink can be fixed on the entire surface of fastener elements. Printing by an inkjet method is carried out at least on the exposed surfaces exposed on the first tape surface side in the tape front- and back direction of the fastener elements, the inner surfaces of the first tape surface side facing the tape inward side, along with the first tape surface of the fastener tape. A desired pattern can thereby be stably formed not only on the fastener tape and the exposed surfaces of the fastener elements, but can also be formed on the inner surfaces of the fastener elements. Therefore, a pattern can be formed in a continuous manner on the fastener tape and the fastener elements, and decorativeness and design unattainable in the past can be obtained.

    Abstract: A golf club head includes a perimeter member made of high density material and a face plate insert made of lower density material. In one embodiment, the face plate insert is formed by applying a shell member to a core member so that the shell member encases the core member. Preferably, the shell member is made by electrodepositing a nanometal having a grain size between 10 and 50 nanometers onto the core member.

  • Patent number: 7331097
    Abstract: A workpiece chuck includes an upper assembly on which can be mounted a flat workpiece such as a semiconductor wafer. A lower assembly is mountable to a base that supports the chuck. A non-constraining attachment means such as vacuum, springs or resilient washers applied to the chuck holds the upper assembly to the lower assembly, the lower assembly to the base and can hold the wafer to the top surface of the upper assembly. By holding the chuck together by non-constraining means, the chuck layers can move continuously relative to each other under expansion forces caused by temperature effects, such that mechanical stresses on the chuck and resulting deformation of the chuck and workpiece over temperature are substantially eliminated. A plurality of support members including inclined surfaces provided between an upper and lower portion of the chuck maintain the top surface of the chuck and any workpiece mounted thereon at a constant height over temperature.

  • Patent number: 7316057
    Abstract: A method (20) of fabricating a large component such as a gas turbine or compressor disk (32) from segregation-prone materials such as Alloy 706 or Alloy 718 when the size of the ingot required is larger than the size that can be predictably formed without segregations using known triple melt processes. A sound inner core ingot (12) is formed (22) to a first diameter (D1), such as by using a triple melt process including vacuum induction melting (VIM), electroslag remelting (ESR), and vacuum arc remelting (VAR). Material is than added (26) to the outer surface (16) of the core ingot to increase its size to a dimension (D2) required for the forging operation (28). A powder metallurgy or spray deposition process may be used to apply the added material. The added material may have properties that are different than those of the core ingot and may be of graded composition across its depth. This process overcomes ingot size limitations for segregation-prone materials.

    Abstract: The present invention provides an improved system and method for casting toilets. In the disclosed method, at least one of a shell, engine and rim configuration for a toilet is provided, wherein the configuration is selected from a plurality of shell, engine and rim configurations defined by a corresponding plurality of shell, engine and rim molds. Each mold defines a casting space therewithin for casting the selected configuration therefrom. Each shell configuration includes a hollow housing space for disposition of a unique sanitaryware performance engine configuration therewithin. While still greenware, the cast engine is disposed in the shell housing space to form at least one shell and engine assembly thereby. Subsequently, and while also in a green state, the cast rim is assembled with the shell and engine assembly and the entire shell, engine and rim assembly is fired to form a single integral piece of sanitaryware.

    Abstract: A method of remodeling a subsisting countertop by casting a polymer-modified cementitious casting compound thereupon has some of the following steps. Given a subsisting countertop, without altering it, temporarily attaching edging forms or flow checks around all the free edges of the subsisting countertop, both of which forms and flow checks operate to check the flow of the casting compound at least to the height of a given rise. Following that, pouring a polymer-modified cementitious casting compound over the countertop to the height of the given rise and as checked within the edging forms and flow checks. The final step involves optionally removing the forms before the lapse of a full day.
