    Abstract: A measuring device for determining the temperature of a medium in a container or a pipe has at least one temperature sensor, arranged on the outside of a container or pipe wall; an output for the temperature registered thereby; and an output for the measurement result obtained thereby. The device connects at least one first differentiator, capable of determining at least one first derivative of the progression over time of the temperature registered by the temperature sensor; at least one first multiplier for multiplying the derivative by a first factor which is a value for the time constant of the heat transfer through the wall; and at least one adder, between the output of the temperature sensor and the output of the measuring device.

    Abstract: A method inspects a conveyor (10) having opposing sides (34, 35) and a length. The conveyor includes an endless belt (16) and a plurality of roller structures (24) disposed in spaced relation along at least a portion of the length of the conveyor and under a top flight (17) of the belt for supporting the belt while material is being conveyed on the belt. Each roller structure includes at least one roller (12, 12′) constructed and arranged to rotate about an axis as the belt is conveyed with the material. The method orients an unmanned vehicle (22), having sensor structure (28) thereon, at one side of the conveyor, and causes the vehicle to travel along the portion of the length of the conveyor while the sensor structure obtains data regarding a state of at least a portion of the belt and of rollers of the plurality of roller structures while the conveyor is operating.

    Abstract: An exemplary transformer protection system including a protective housing having a transformer which is arranged in the protective housing, a transformer core, and at least one primary-side electrical winding and a secondary-side electrical winding which is magnetically coupled to the primary-side electrical winding. The protection system also includes at least one detection apparatus for a measurement variable from which the occurrence of an interference arc within the protective housing can be derived, and an evaluation unit for generating a fault signal from the measurement variable of the at least one detection apparatus in the case of an interference arc. Further, the protection system includes at least one rapid-earthing apparatus for at least one of the electrical windings which is intended to be activated by the fault signal, wherein the rapid-earthing apparatus is designed in such a way that effective electrical earthing immediately after activation of the fault signal is ensured.

    Abstract: A method to determine the magnitude MA of a signal component with frequency ωA from a set of N digital samples of an input signal acquired at a sampling rate R, said input signal having a discrete spectral representation having n bins with frequencies ω1, . . . , ωn and corresponding magnitudes M1, . . . , Mn, the spectral representation being derivable from the input signal using a transform, involving choosing an extraction bin with index kε[1, . . . , n] and frequency ωk≠ωA from the spectral representation; determining a magnitude Mk of this extraction bin; determining an allocation factor indicating a portion Mks of a sinusoidal signal with frequency ωA and unity magnitude that is allocated to the extraction bin when the transform is applied to the sinusoidal signal to generate a spectral representation out of the sinusoidal signal; and determining the magnitude MA of the signal component from the magnitude Mk of the bin in combination with the factor.

    Abstract: An exemplary control apparatus for an energy distribution system includes a connection to an alternating current supply system and a plurality of predetermined loads each having an energy storage capacity and being electrically connected as by a respective switching device to the alternating current supply system for a duration of a half-wave or a whole number times said half-wave. The respective switching devices are supplied electrical energy from the alternating current supply system for a respective control time period within a predetermined common cycle time period. The start and end of the respective control time periods within the common cycle time period are established prior to the start of said common cycle time period to create a substantially constant loading graph. The optimization procedure is based at least one load in lieu of a continuous control time period having at least two non-continuous block time periods of equal total duration.

    Abstract: An electric machine can include a stator, a rotor frame and a pole arrangement with: plural segment pieces disposed circumferentially around, and fastened to, the rotor frame; permanent magnet pieces positioned on inclined side edges of each segment piece; and plural pole pieces disposed circumferentially around the rotor frame and disposed alternatingly with the segment pieces. The magnet pieces are pressed between inclined side edges of the pole pieces and the inclined side edges of the segment pieces. The segment pieces, the permanent magnet pieces and the pole pieces form a closed ring around the outer surface of the rotor frame, with plural such rings being arranged after each other in an axial direction. An axial air channel can pass through the rings, and at least one radial air duct (R1, R2) between the rings.
