Abstract: The invention relates to an arrangement for evaluating the condition and quality of low-voltage networks, in the branched system of which a multiplicity of connected consumers are located, by ongoing or cyclical determination of network measurement data by current and voltage analysis on the basis of power quality measuring and testing devices with transmission of the network measurement data by means of interfaces to a superordinate system or in retrievable form to a server or to the Cloud, wherein the measuring and testing devices are integrated in an assembly with external connections.

Abstract: The invention provides a surge protector, in particular for information technology and/or communications technology systems, which is equipped with: a housing (ST, BT; GT); a first input terminal (E1) for applying a first external voltage signal; a second input terminal (E2) for applying a second external voltage signal; a first output terminal (A1) for outputting the first external voltage signal; a second output terminal (A2) for outputting the second external voltage signal; a surge protection circuit device (G1, R1, Z1; G1, G2, R1, R2, Z1; G1, G2, R1, R2, Z1, Z2), at least part of which is provided on a circuit board (P) located in the housing (ST, BT; G); a first current path (ST1) for conducting the first external voltage signal from the first input terminal (E1) to the first output terminal (A1) bypassing the surge protection circuit device (G1, R1, Z1; G1, G2, R1, R2, Z1; G1, G2, R1, R2, Z1, Z2); a second current path (ST2) for conducting the second external voltage signal from the second input termin

Abstract: The invention relates to a circuit assembly for the state monitoring and logging of overvoltage protection devices or overvoltage protection systems by means of pulse current monitoring, comprising at least one passive RFID transponder having an inductively coupled voltage supply, wherein in the case of an event of the overvoltage protection device or the overvoltage protection system, the RFID transponder antenna circuit is influenced, in particular interrupted, short circuited, or detuned, so that disturbance processes can be identified.

Abstract: Implementations of the present invention relate to a scanning probe microscope, which includes a base frame to which a probe holder with a probe as well as a probe support are, or can be fixed. The probe and the sample mount can be moved relative to one another in order to obtain information about the surface of the sample by scanning a sample which is arranged on the sample mount. Furthermore, a reaction chamber can be attached to the base frame of the scanning probe microscope, with the sample mount arranged therein. The reaction chamber has an opening on its side facing the probe, through which the probe can enter the reaction chamber. The reaction chamber can enable treatment of the sample's surface by the specific influence of fluids within the reaction chamber when the reaction chamber is closed.

Abstract: The invention relates to synthetic aluminum silicates having a nepheline or carnegieite structure which have a thickening effect in aqueous systems of suspensions and solutions. The invention further relates to the preparation of such synthetic aluminum silicates and their use as thickeners and suspending and thixotropic agents for ceramic bodies, glazes and enamels. Finally, glaze and enamel slips, ceramic bodies, colors and pastes containing the above mentioned synthetic aluminum silicates are also provided.

Abstract: Method and apparatus in which dispenser cap assemblies of the type having a trigger-type pump cap and a dip tube are fed to a generally cone-shaped drum which rotates about a vertical axis and carries compartments within which the cap assemblies are moved in a generally spiral outward direction while moving axially downwardly to be oriented vertically, with the cap below the dip tube, the cap assemblies then being transferred to a turnover wheel which rotates about a horizontal axis so that the cap assemblies are inverted to re-orient each cap assembly into a position where each dip tube depends vertically downwardly from the respective cap, the cap assemblies then being passed to a horizontal conveyor for advancement to a discharge point where the cap assemblies are presented serially in a prescribed alignment and orientation, at a relatively high rate, for capping operations.

Abstract: An apparatus for aligning the edges of a stack of sheets comprises a base and two plates mounted on the base for movement independently of one another. An oscillatory drive arrangement imparts oscillatory motion to the plates, the amplitude, frequency and orientation of the oscillatory movement being independently adjustable for each of the plates. A stack of sheets the edges of which are to be aligned is arranged on the plates so as to be supported on the plates on their support edges, and the oscillatory motion causes the individual sheets to move in a predetermined direction until the leading edges of the individual sheets reach an abutment preventing further movement of the sheets. A substantial volume of low-pressure air is blown between the individual sheets so as to separate them from one another and facilitate their independent movement toward the abutment. A pair of upright walls extends parallel to the direction of movement of the sheets so as to laterally support the stack.
