Abstract: A turbine-blade locking device having a wedge movable in an axial direction is disclosed. The wedge is movable in the axial direction by a tensioning device, as a result of which a force is produced in the axial direction. The force in the axial direction causes the turbine blade to be pressed against the blade holder.

Abstract: A damping system for damping the vibrations of a blade union is provided. The blades arranged in a neighboring manner are coupled to one another via a coupling element, wherein the coupling element is arranged fixed in a first blade and extends into the second blade, wherein the coupling element is not arranged in the second blade but rather solely contacts there such that, as a consequence of centrifugal forces, a free end of the coupling element presses against the second blade and a friction force thus occurs, leading to an energy dissipation and vibrations being thus damped.

Abstract: In the method of producing smaller, sheet glass plates having a predetermined geometry and lateral dimensions in the millimeter range from a larger sheet glass plate, a joining material is imprinted on one side of the larger sheet glass plate in accordance with a joining zone geometry of the smaller, sheet glass plates. Dividing lines along which the smaller, sheet glass plates are separated are specified on the larger sheet glass plate. Then the smaller, sheet glass plates are separated along the dividing lines together with the imprinted joining material into individual sheet glass plates.

Abstract: A method of determining the level of the effect of each system entity on the overall system performance, wherein the status of each entity at each one of discrete points of time is determined as the corresponding one of an active and an inactive status; the length of the active period in which each entity is situated without interruption in the active status is determined as an active time; and, on the basis of the relationship in magnitude between the system entities with respect to the determined active time, the level at which each entity affects the performance of the system is determined.

Abstract: A method of estimating a measure of randomness of a function of at least one representative value of at least one random variable is constructed to have the steps of obtaining the at least one random variable; determining the at least one representative value of the obtained at least one random variable; determining a first statistic of the obtained at least one random variable; determining a gradient of the function with respect to the determined at least one representative value; and transforming the obtained first statistic into a second statistic of the function, using the determined gradient. The step of transforming may be adapted to transform the first statistic into the second statistic, such that the second statistic responds to the first statistic more sensitively in the case of the gradient being steep than in the case of the gradient being gentle.

Abstract: Small sheet glass plates (2) of this type with a predetermined geometrical structure are conventionally produced by being cut out of a larger sheet glass plate (1). The small sheet glass plates (2) that have been separated in this way, together with a jointing cement, in particular a solder frame (3) consisting of glass solder are then attached to other components, for example to be used in “electronic packaging”. In order to improve handling during the production and the jointing of the small sheet glass plates (2), the invention provides a larger sheet glass plate (2) which is patterned on both sides using a screen-printing or stencil-printing process and preferably using laser beam treatment along desired predetermined breaking points (5). Said larger glass plate can then be separated into smaller, patterned plates, i.e. the small sheet glass plates (2), whose shape is geometrically determined, by a simple preferably mechanical breaking process.
