Abstract: A system for measuring the position of a rod element as, for example, a hydraulically or pneumatically operated piston rod. Unlike the prior art, the system according to the present invention employs a measuring principle that does not require preparatory treatment of the rod element as is required in the known solutions. The system employs direct time of flight measurements with the aid of acoustic surface waves that are introduced into the rod element. The instrument is retrofittable on existing cylinders without any modification/reconstruction thereof. An EMAT principle is employed to introduce the surface waves into the measurement in a non-contact manner.

Abstract: A system for transmitting electrical signals and/or electrical energy via an electrically conductive medium, in which a plurality of electric wound coils is mounted on each side of the electrically conductive medium, conductors of the plurality of electric wound coils are arranged in parallel with respect to one another and each of the plurality of electric wound coils is oriented relative to each other in such a manner that winding wires are predominantly vectorially mounted in parallel, the conductors are mounted predominantly parallel to surfaces of the electrically conductive medium, the system reacts when a current is applied to the electric wound coils, thereby generating a magnetic field and generates an eddy current which circulates between an external and an internal surface of the electrically conductive medium, and a voltage is induced in the electric wound coils from the eddy current.

Abstract: The present invention relates to system for measuring pressure and temperature based on change in the characteristic properties of a medium for ultrasound under the effect of pressure and temperature. The invention is based on two waveguides where geometry is adapted to the medium's characteristic properties for ultrasound such that only planar pressure waves are generated in the waveguides. The first of the waveguides is arranged for measuring temperature due to thermal expansion of the medium, where the medium is pressure-compensated by means of an internal compensator to prevent thermal pressure accumulation, and where measuring temperature is based on the medium's specific known characteristic data for ultrasound under the effect of temperature under constant pressure.

Abstract: Driving arrangement (11) for a pump, compressor or similar, adapted to provide alternating pressure in at least two chambers (27a, 27b, 27?, 27?), such as chambers of a pump or compressor, as result of a reciprocating movement of a bar element (23). The bar element is connected to two movable pressure chamber faces being pistons (21a, 21 b) or plungers having fluid connection to said chambers, which bar element (23) is reciprocally supported in a housing (19). The driving arrangement further comprises an electric motor (31) which is adapted to provide the reciprocating movement of the bar element (23). The bar element extends through the rotor (31b) of the electric motor (31). The electric motor is an electric rotary motor. The invention also relates to a pump assembly with a plurality of such driving arrangements.

Abstract: A universal rail for a firearm has a plurality of through holes and a plurality of attachment points for ancillary equipment along a length of the universal rail, a fastener so as to be fastenable to the firearm, and a power or signal connection point arranged in at least one attachment point of the plurality of attachment points. The power or signal connection point has at least two contact pins surrounded by a seal, and a resilient portion and inner contact faces. The power or signal connection point is further connected to conductors arranged in the universal rail. The resilient portion ensures that the at least two contact pins and contact points are out of contact with each other when the ancillary equipment is not mounted on the universal rail.

Abstract: The invention relates to a type of shock and vibration isolator which has almost identical rigidity and damping properties in any translatory direction, wherein the device is disposed between a reference object (A) which is subjected to vibrations and shocks, and a means (B) which is only to be subjected to translatory damped vibrations and shocks in all directions, where a center bar (2) and wire rope holders (3) are designed for attachment to any one of the reference objects (A) or (B), characterized in that the center bar (2) and the wire rope holders (3) are rigidly interconnected to three or more independent wire rope series (4), each of which is formed of two or more wire rope loops where the configuration of a wire rope series (4) is based on essentially as many wire rope loops with opposite geometrical angles of inclination (A1 and A2), each wire rope series forming a symmetry along a center axis relative to an unloaded neutral position for the isolator and where the three or more wire rope series (4)
