The present invention provides a stent remover for open surgery which can be used to safely remove a stent without causing tissue damage. In a first step, at least three wires are threaded through the mesh of one end of the stent. Then, all wire ends are fed through a sleeve and fixed with a crimping device. Afterwards, the wires in the sleeve can easily be introduced into the funnel-shaped tube of the stent remover. By operating the turning knob of the device, a uniform and controllable pulling force is exerted to the wires. In this way, the stent constricts evenly and can easily be removed without serious tissue damage. In addition, stent removal with this novel device shortens the operation time, thereby reducing the potential for unforeseen complications. On behalf of RWTH Aachen University, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development.

In principal all known conventional satellite navigation systems like GPS, Galileo, GLONASS, QZSS and BeiDou are enabling the determination of the position with accuracy on the centimeter-level by help of the carrier phase. However, the carrier signals, upon which the navigation signals are modulated, are typically impaired by various error sources, like ionospheric errors, tropospheric errors, instrumental errors and/or other error sources, leading to a defective determination of the position. The invention enables a precise and reliable relative positioning (relative kinematic positioning – RTK) with centimeter-level accuracy in urban environments as well as a precise attitude determination (heading estimation with 0.25°/m accuracy) with low-cost sensors. Wit the new method the above mentioned errors can be
eliminated reliably.

The invention concerns hybrid carbon fibre composite parts, whose surfaces are trued up by foils, additional surface processes are obsolete.

But now, a research assistant professor Norio Narita of the Astrobiology Center of National Institutes of Natural Sciences (NINS), which was founded in April…

CF flanges are well-established components for building ultra-high-vacuum environments. There are several geometries of the tubes that follow the ISO/TS 3669-2 standard, so that the costumer can combine products from different companies.
Nevertheless, a rather tricky task remains: For sealing the contact points between two different CF flanges, the technician has to mount a thin gasket between the two outer ends of the flanges before tightening the bolts. The gasket is typically made of high purity copper. When tightening the bolts, the extruded metal leads to a leak-tight seal (see Figure 1). Mounting and positioning of the copper seal still remains manual work – the technician has to fix the ring in the right position until the bolts hold the two flanges in place. Even if the technician is well trained, the gasket is likely to move and drop out when handling heavy components (pumps, evaporation devices, sections of the vacuum system, etc.). This is a waste of time and money – the damaged copper gasket can’t be reused.
Our new positioning device eliminates the need for this tedious and rather complicated positioning of the sealing ring by hand.

A novel divergent nozzle design, which provides for a homogeneous flow profile even at long distances from the nozzle exit, was developed at the University of Stuttgart. The flow profile is optimized by a central body, shaped and placed in the flow channel in such a manner as to achieve a uniform flow and temperature distribution at the target object. Based on these characteristics, the invention is particularly suited to be used as a long range nozzle for large penetration distances in drying and ventilation applications.
