Abstract: An electric fail-safe actuator includes a speed reducer/gear assembly housing arranged between one or more electric motors, and a rotation to linear transformer including a roller or ball nut and a screw, or a nut and a roller or ball screw. The speed reducer/gear assembly housing is connected to an actuator housing via a counter hold release mechanism, allowing the speed reducer/gear assembly housing to co-rotate with a rotational side of the rotation to linear transformer when the counter hold release mechanism is released.

Abstract: A device for determining the connection quality of threaded tubular components includes a case configured for mounting on an external surface portion of a threaded tubular component, at least one measuring device including a contact layer including a plurality of temperature sensors arranged to measure variables representative of temperatures at a plurality of locations E(i,j) of the external surface of the end of the tubular component.

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: 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: 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.
