Abstract:
A sensing device for measuring force and/or torque includes a top part with a top electrode structure, a bottom part with a bottom electrode structure, and a support structure. The support structure (7) includes spring elements for supporting the top part on the bottom part with the top electrode structure (4) parallel to and facing the bottom electrode structure (6). The spring elements provide a gap between the top and bottom electrode structures (6) and allow displacement of the top part relative to the bottom part in three orthogonal directions two parallel and one perpendicular to the bottom plate, and for rotation of the top part relative to the bottom part around three orthogonal axes, corresponding with said two parallel and one perpendicular directions. The displacement and/or rotation induce a change in distance between and/or overlap area of the top and bottom electrodes and a corresponding change of capacitance.
Abstract:
The present invention relates to a process for manufacturing a hollow fibre membrane having a supporting layer and a separating layer, said process comprising: (a)extruding a spinning composition comprising a first polymer and a solvent for the first polymer through an inner annular orifice of a hollow-fibre die; (b)co-extruding a composition comprising an organic nucleophilic reagent and a mixtures of a solvent and a non-solvent for the first polymer, wherein the composition is either extruded through a central annular orifice of the hollow-fibre die or through an outer annular orifice of a hollow-fibre die; and (c)passing the hollow-fibre through a coagulation bath. The hollow fibre membrane according to the present invention can be used in gas separation processes, vapour separation processes and liquid filtration processes.
Abstract:
The invention relates to a device for providing a controlled friction on a rotation shaft rotatably arranged on a base, which device comprises: - a friction generating device having a rotatable part connected to the shaft and a stationary part connected to the base; - a pressure sensor arranged between the stationary part and the base in order to measure the counter-force; and - control means for controlling the friction generating device based on the pressure measured by the pressure sensor.

Abstract:
Disclosed is a continuous method of size-sorting microbubbles, comprising: providing a polydisperse plurality of microbubbles (70); entraining said microbubbles (70) in a fluid flow (46) flowing in a flow direction (x+) towards a collection location (62); at an insonification location (60) upstream of the collection location (62), subjecting the microbubbles (70) in said fluid flow (46) to an acoustic pressure wave (52) propagating in a wave direction with a non-zero directional component in a microbubble segregation dimension (y) that extends perpendicular to the flow direction (x+), thereby segregating microbubbles of different equilibrium radius (ro) in said microbubble segregation dimension (y) as they pass the insonification location; and at said collection location (62), collecting the microbubbles (70) present within at least two spatial ranges (44a-c) of said microbubble segregation dimension (y). Also disclosed is an apparatus (1) implementing the method.
