Abstract: In the measurement of properties of a wafer substrate, such as Critical Dimension or overlay a sampling plan is produced defined for measuring a property of a substrate, wherein the sampling plan comprises a plurality of sub-sampling plans. The sampling plan may be constrained to a predetermined fixed number of measurement points and is used to control an inspection apparatus to perform a plurality of measurements of the property of a plurality of substrates using different sub-sampling plans for respective substrates, optionally, the results are stacked to at least partially recompose the measurement results according to the sample plan.

Abstract: The invention relates to a valve for controlling a coolant circuit of a refrigerating system, having a housing, which has at least one inlet opening and at least one outlet opening, having a regulating chamber provided in the housing, which extends between the at least one inlet opening and the at least one outlet opening, having a valve arrangement, which is insertable at least partially into the regulating chamber, having a rotary slide arrangement, arranged in the regulating chamber, which has a control disc, which is rotatable in relation to the at least one rotary slide support, the at least one rotary slide support is provided non-rotationally to the housing and the at least one rotary slide support is mounted floatingly to the housing.

Abstract: A flow control system, such as a thruster, includes an annular rotor within an annular housing. The annular rotor rotates about a central axis relative to the annular housing. The flow control system includes rotor blades with respective bases that are coupled to the annular rotor, and with respective tips directed toward the central axis. The flow control system includes a first actuator that rotates the annular rotor about the central axis relative to the annular housing, thus also rotating the rotor blades about the central axis relative to the annular housing. The flow control system includes a second actuator that rotates the rotor blades relative to the annular rotor. Actuation of the second actuator rotates a rotor blade about a rotor blade axis that extends from a base of the rotor blade toward the central axis.

Abstract: This invention relates to methods and materials for slip ring grinding of a generator rotor, without the need of dismounting the slip ring from the rotor of the generator, and allowing the grinding process to be performed whilst the generator is on full-load operation. As such the methods and materials of the present invention differs from current solution. Whilst allowing on-line grinding of the slip ring, the current solutions require low-speed rotations and accordingly operational shutdown of the generator. Allowing on-load grinding, the present invention greatly shortens the downtime of the generator and to perform maintenance on the slip ring beyond the provided standard maintenance schedule.

Abstract: A display for a watchband includes a housing member having a first shell and a second shell member, each shell having a joining means, when assembled such first and second shell members form a cavity. At least a portion of a top surface of such second shell of such housing member is transparent. A predetermined power source is located at a predetermined location within such cavity. A control unit is located at a predetermined location within such cavity operably connected to such power source and having an integrated circuit with a clock function to output day, date and other information. A display mechanism is located within such cavity operably connected to such power source and such control unit. An input mechanism on such housing member is operably connected to such control unit. A band attaching mechanism attaches such housing member to such watch band.
