Abstract: A piston for an internal combustion engine has shaft elements which have inner surfaces that correspond to those regions of the shaft elements in which the shaft elements are thinner than 7% of the piston diameter “D”, and have outer surfaces that define in a radially outward direction those regions of the shaft elements which, viewed in the circumferential direction, lie outside angle ranges of more than 40° on both sides of the pin bore axis. The ratio of the content of the inner surface to the ratio of the content of the outer surface is more than 60%. The shaft elements hereby become elastically compliant, which upon a temperature-induced radial expansion of the piston shaft reduces the pressure that the shaft elements exert on the cylindrical inner wall, whereby the friction losses of the piston, and hence the CO2 emission of the engine fitted are reduced.

Abstract: A method for operating a steam reforming plant wherein a hydrocarbon-rich feed is reacted with steam to form synthesis gas. The plant includes a steam reforming reactor and processing units to obtain a hydrogen-rich fraction after separation of carbon dioxide and carbon monoxide. The plant also includes a pressure-swing adsorption plant to separate the hydrogen-rich fraction into product and residual gas. A recycle compressor is included and allows the plant to operate is two different modes. In the first mode, carbon dioxide separated from the synthesis gas is compressed and added to the hydrocarbon-rich feed. In the second mode, the recycle compressor is used to recycle residual gas from the pressure-swing adsorption plant to the hydrogen-rich fraction upstream of the pressure-swing adsorption plant.

Abstract: A sintered composite body of cemented carbide and cBN grains, wherein the cBN grains are dispersed in a cemented carbide matrix. The body further includes a cBN depleted zone extending 50-400 ?m from the surface of the body towards the core thereof. The mean cBN grain size outside the depleted zone is 1-20 ?m and the cBN content outside the depleted zone is 0.3-4 wt %.

Abstract: The invention relates to a piston (1) for an internal combustion engine having shaft elements (8, 9) which have inner surfaces (17, 18) that correspond to those regions of the shaft elements (8, 9) in which the shaft elements (8, 9) are thinner than 7% of the piston diameter “D”, and have outer surfaces (14, 19) that define in a radially outward direction those regions of the shaft elements (8, 9) which, viewed in the circumferential direction, lie outside angle ranges (20, 20?) of more than 40° on both sides of the pin bore axis (15). In this connection, the ratio of the content of the inner surface (17, 18) to the ratio of the content of the outer surface (14, 19) is more than 60%.

Abstract: Example methods and apparatus to implement electronic book viewers are disclosed. A disclosed example method involves presenting content on a display panel removably attachable to a binding element. The binding element is configured to receive one or more other display panels in a removably attached configuration to form an electronic book. The example method also involves enforcing a content protection policy associated with the content presented on the display panel based on an attachment status of the display panel. The attachment status is associated with the removable attachability of the display panel relative to the binding element.

Abstract: Systems and methods control resizing a presentation of an image on a flexible display. A user flexes a flexible display in a particular manner to control magnification or size reduction of the image presented on the display. The amount of magnification or size reduction of the image presented on a flexible display increases along with the absolute magnitude of flexible display flexing. The flexible display can be double flexed within a defined time to indicate that another action is to be taken, such as fitting the presently displayed document to the width of the flexible display or fitting the entire document to the flexible display. The direction of flexing, such as flexing in a concave or a convex direction, is a flexing characteristic that causes other desired actions.

Abstract: A reduction in the intersection of vias on the last layer (“VL”) and holes in the last thin metal layer (“MLHOLE”) can be achieved without degrading product yield or robustness or increasing copper dishing. The mutation of some dense redundant VLs to MLHOLEs decreases the number of intersections between VLs and MLHOLEs.

Abstract: A patterned buried insulator is formed beneath the source and drain by forming a mask over the body area and implanting a dose of n or p type ions in the areas where the source and drains will be formed, then etching the STI and etching out the implanted area. A light oxidation is followed by a conformal oxide deposition in the STI and also in the etched area, thereby forming the buried oxide only where desired.
