Abstract:
Apparatus and method for removing, installing and/or testing valve-spring retainer assemblies of internal combustion engines and the like employ an existing spark plug opening (40) to mount a tool (44, 64, 80) which is designed to depress a valve spring (22) and thereby disengage an associated valve-spring retainer assembly (26, 28). Once it has been disengaged, at least a portion of the valve-spring retainer assembly can be removed from a cylinder head (10) of the engine through the tool.
Abstract:
Methods and systems for fabricating platelets of a monochromator for X-ray photoelectron spectroscopy (XPS) are disclosed. For example, a method of fabricating a platelet of a monochromator for X-ray photoelectron spectroscopy involves placing a crystal on a stage of an X-ray measuring apparatus, the crystal having a top surface. The method also involves measuring, by X-ray reflection, an orientation of a crystal plane of the crystal, the crystal plane beneath the top surface of the crystal and having a primary axis. The method also involves measuring a surface angle of the top surface of the crystal by measuring a light beam reflected from the top surface of the crystal.
Abstract:
An automated tool and method for spacing a gap between the anti-vibration bars and the flow tubing in the bend region of a tube bundle of a U-tube steam generator, prior to welding, during manufacture. The tool comprises two toggle clamp elements attached to a scissors assembly, which are actuated by a linear drive motor in line with a force gauge, and coupled to a distance measuring device. The tool is operated by first attaching the toggle clamps respectively to two adjacent anti-vibration bars. A linear drive motor on the tool is then cycled and readouts of force and distance are plotted on a curve to determine the point of contact between the anti- vibration bar and the tube. The computer then automatically cycles the drive motor to adjust the gap to a desired range of position coordinates adjacent the point at which the curve markedly changes slope.
Abstract:
An electronic module (20, 39, 60, 80, 132, 140, 144) includes a substrate (21), which includes a dielectric material having a cavity (40, 42, 134, 142) formed therein. First conductive contacts (44) within the cavity are configured for contact with at least one first electronic component (32) that is mounted in the cavity. Second conductive contacts (44) on a surface of the substrate that surrounds the cavity are configured for contact with at least a second electronic component (28, 30) that is mounted over the cavity. Conductive traces (36, 48) within the substrate are in electrical communication with the first and second conductive contacts.
Abstract:
A method for fitting cables (13) with seals (1 ), in which the seals (1 ) are accommodated via a transfer unit and mounted on the mentioned cable (13). While the seal (1 ) is being accommodated via the transfer unit, its orientation on the holding arbor (2) is mechanically-electrically and fully automatically checked. If a seal (2) is incompletely or partially punched through, it is removed from the holding arbor (2). Equally, a seal (2) which is not accommodated by the holding arbor (2), is removed from the accommodation area. Also a transfer unit for seals (1 ) or comparable cable fitting components for a cable processing plant, the transfer unit encompassing a holding arbor (2) for accommodating seals (1 ), wherein at least one force and/or pressure transducer (3) is situated on or in the holding arbor (2).
Abstract:
The present application discloses methods and apparatus for installing fitting components, such as a conduit gripping device, on a conduit to form an assembly. The assembly is joinable with at least one other fitting component to form a fitting. The present application also discloses methods and apparatus for evaluating characteristics of components of a mechanically attached connection. Characteristics that may be evaluated include, but are not limited to, the position of a conduit gripping device on a conduit, an amount of axial compression or stroke of the conduit gripping device, an amount of clamping force applied to the conduit gripping device as the conduit gripping device is compressed, and an amount of torque applied to members that compresses the conduit gripping device.
Abstract:
The invention relates to a method of aligning a wind turbine component with a wind turbine rotor hub (3), characterised in that it comprises the steps of providing the component with a support comprising at least one adjustable element (20) and adjusting said at least one element to align the wind turbine component. The invention further relates to a system for aligning a wind turbine component with a wind turbine rotor hub comprising a support with at least one adjustable element (20) supporting said wind turbine component, such that said wind turbine component can be aligned by adjusting said at least one element (20).
