Abstract: A device for measuring concentration of a flowing suspension wherein a moveable detector body (3) is arranged for detecting the resistance against movement in the suspension, and including a flow modifying element (4) for bringing a portion of the suspension which is representative of the concentration of the suspension flow to the region of the detector element (3). The invention is distinguished by the flow modifying element being a fixed deflector (4), which is arranged to deflect a boundary layer (7) of the suspension flow closest to the conduit wall (1) such that it is brought away from the region of the detector body (3). The invention also concerns a method for measuring concentration and a deflector.

Abstract: A device for measuring a parameter such as the mass concentration or the viscosity of a fluid medium such as a suspension or a liquid, including a rotor for rotation in the medium, a drive motor, a drive transmission with a drive shaft for the rotor, and a sensor device for sensing the torque which is transmitted to the rotor and which represents the parameter. The device is distinguished by that the sensor device includes an excitable frequency gauge which is deformed by the torque, and the prevailing natural frequency of which his dependent on the deformation and directly detectable by a stationary detector, which is placed outside the transmission.

Abstract: The invention relates to an arrangement in regulating valves for steam, gases or liquids and includes a cage (2) fixedly disposed in a valve housing (1), there being a movable valve body in the cage, the body (3) being positionally settable in the fixed cage (2) via a spindle (4) such as to be sealingly engageable via a sealing surface (5) formed on it against a seating (6) formed in the valve housing (1), the body (3) during its movement to its upper, i.e. fully open, position successively uncovering orifices (9) in the fixed cage (2) for achieving a gradual increase in through-flow area in the valve.

Abstract: The invention relates to improvements in or relating to a desuperheater for controllable injection of cooling water in a steam or gas line (17), said desuperheater device including an insertion tube (1) extending inside the pipe (17), said tube (1) having a conical outlet nozzle (7) with a valve body (5) movably arranged in a hole (2) in the insertion tube (1) such as to form a regulating port (4). The hole (2) in the insertion tube (1) opens out into a rotation chamber (3) with the centerline (10) of the hole and the centerline (11) of the rotation chamber (3) disposed relative each other at an angle deviating from 90.degree. by an angle .alpha., and where the angle .alpha. is greater than 0.degree. but less than 30.degree..
