Mechanical, electronic, algorithmic, and computer network facets are combined to create a highly integrated advanced gas sensor system. The sensor system, utilized with gas insulated high voltage switchgear products, deployed by electric utility end users in replacement and expansion cycles, function to detect and mitigate atmospheric pollution caused by leaking SF6. As its associated gas insulated tank is charged with 10 to 350 lbs. of SF6, each gas sensor monitors its local cache of gas, accurately sensing and computing fractional percentage losses (emissions) and gains (maintenance replacement) in SF6 mass, storing data in onboard data logs, and communicating data when triggered by detection events or in response to remote requests over a hierarchical communications network, a process that continues without labor until a fractional leak is automatically detected and reported creating the opportunity for early leak mitigation.

A pump for the transporting of fluids and / or of mixtures of fluids includes a housing (1) and at least one restrictor gap seal which is provided in the housing (1) to reduce the pressure in a restrictor gap along a rotatable part (2) of the pump, wherein the restrictor gap seal is formed as a brush seal arrangement (8). The brush seal arrangement (8) contains one or more individual brush seals (8′) which include as sealing members a plurality of sealingly arranged fibers, bristles and / or wires (8a) which are distributed and fastened in ring form and whose free ends extend towards the surface to be sealed.

A polyphase converter circuit having p≧3 phases (R, Y, B) and a converter circuit element provided for each phase (R, Y, B) is specified, each converter circuit element having a rectifier unit, a DC voltage circuit which is connected to the rectifier unit and an inverter unit which is connected to the DC voltage circuit. In addition, a first AC voltage output of each inverter unit forms a phase connection, and second AC voltage outputs of the inverter units are star-connected. In order to produce harmonics which are as low as possible with respect to the fundamental of the voltage and the current of an electrical AC voltage system which is connected on the input side to the converter circuit, n transformers are provided, each having a primary winding and m three-phase secondary windings, where n≧2 and m≧3. Furthermore, p sets of secondary windings are provided, each set of secondary windings being formed by in each casempthree-phase secondary windings of each transformer, and each set of secondary windings with the associated secondary windings being connected to the rectifier unit of a respective converter circuit element.

In a hand-held power tool having a planetary gearbox which is situated in a housing interior formed by a gear housing, at least one cross pin is fastened in the housing interior for axial support of the planetary gearbox in the gear housing.

An electromagnetically operated valve, comprises a valve slide with a magnet armature, which is equipped to close a sealing seat in a fluid channel of the valve with a first axial end in a closed position, as well as a sealing element with folded bellows situated between the sealing seat and the first axial end of the valve slide and separates the valve slide from the fluid channel with a fluid-tight seal. The magnet armature is supported in the valve in an essentially non-contact manner due to the fact that the valve slide has a guide pin protruding in the axial direction from the magnetic armature on a second axial end opposite the first axial end, the guide pin being supported to slide in the axial direction; and the valve slide is aligned in the radial direction on a side of the magnet armature facing the first axial end of the valve slide and is supported so it is movable in the axial direction by means of at least one spring element.

The detection device comprises a cold finger which performs the thermal connection between a detector and a cooling system. The cold finger comprises at least one side wall at least partially formed by an area made from the amorphous metal alloy. Advantageously, the whole of the cold finger is made from the amorphous metal alloy.

A force sensor device (200) for detecting a weight of a vehicle. The force sensor device (200) includes an elongated sensor mount (2) with a plurality of hollow sections (3) arranged at least partially overlappingly in the elongated sensor mount (2). A force strip sensor (1) is arranged in each hollow section (3).

An articulated arm comprises first and second coplanar members comprising first and second toothed portions meshed with one another and separated by an intermediate piece to which each member is connected by a first, second pivot connection from first, second axes, the intermediate piece being monobloc and having a central body integral with a first and a second shaft defining the first and second axes, the first and second shafts being separated by an opening through the central body and able to allow the passage of a cable kept away from the first and second toothed portions by the closed outline of the opening.
