Abstract: The present invention relates to monolithic structures for use as an electrical contact. In particular, these structures are formed from a laminate alloy, which in turn is composed of a Mn+1AXn compound. Electrical contact assemblies and electrical components having such contacts are also described herein. In some example, such monolithic structures display increased wear resistance, which is useful for sliding electrical contacts.

Abstract: The invention relates to an electrical contact arrangement for high pulsed currents and for connection with a polygonal socket. The electrical contact arrangement includes first contact, arm, a second contact arm, an intermediate space provided between the first and second contact arms, and a third contact arm. The second contact arm positioned apart from the first contact arm in a deflection direction extending perpendicularly to the plug-in direction. The first contact arm and second contact arm extend substantially in a plug-in direction, and one of the first contact arm or second contact arm resiliently deflectable relative to the other contact arm in the deflection direction. The third contact arm extends in the plug-in direction and is positioned apart from the first contact arm and the second contact arm in a transverse direction extending perpendicularly to the plug-in and deflection directions. The third contact arm movable in the deflection direction and into the intermediate space.

Abstract: A dispersion containing a high-surface-area, pyrogenically-produced aluminium oxide with a surface area and BET of more than 115 m2/g and a Sears number of more than 8 ml/2 g, is produced by mixing a high-surface-area, pyrogenically-produced aluminium oxide having a BET specific surface area of more than 115 m2/g and a Sears number of more than 8 ml/2 g, with water, setting a pH value of 2 to 11 (preferably 3 to 8) and dispersing the mixture by the introduction of controlled shearing forces. It can be used for the production of Inkjet media, digital imaging products and other printing medium.

Abstract: Method and apparatus for stopping output of a correspondence are provided. A correspondence is created and it is determined whether an automatic flag is defined in the user settings for the correspondence and if the automatic flag is set. If it is determined that the automatic flag is not defined in the user settings, it is determined whether an automatic flag is defined in customizing for the correspondence. If the automatic flag is not set in the user settings or the automatic flag is not defined in the customizing, the correspondence is stored in a storage area and output is initiated. The correspondence is then rendered.

Abstract: Aqueous dispersions of a pyrogenically-produced aluminum oxide are prepared form a mixture containing water, additives and a high-surface-area pyrogenically-produced aluminum oxide with a BET specific surface area of more than 115 m2/g and a Sears number of more than 8 ml/2 g using controlled high shearing conditions. Prior to subjecting the mixture to high shear conditions, the pH of the mixture is adjusted to a value between of 2 to 11 (preferably 3 to 8). The aqueous dispersion has a mean particle size distribution of d50<150 nm. These dispersions are useful in the production of Inkjet media, digital imaging products and other printing media and result in high color densities, photo-realistic reproductions and particularly good print and gloss quality.
