Pinch valves are operated by squeezing a flexible tube in a part of the valve by either moving a separate squeezing device against the tube or by impinging the squeezing part with an actuator. However, with current state of the art valves it is necessary to manually insert the tube between the squeezing device and the counter bearing which is in most cases rather complicated. Besides this, most of the pinch valves are as well pretty large and cannot be used in miniaturized or highly integrated systems. Thus the secure dosing of liquids that contain cells or other solids is with the currently available valves only possible when using exchangeable pinch valves.<br><br> <strong>Technology</strong><br> HScientist at the Technische Universität Berlin have now developed a pinch valve that overcomes the current disadvantages of the state of the art as it can be integrated into existing dosing systems as inexpensive single use valve.<br><br> It allows dosing very little amounts of liquid in a very fast, precise and highly dynamic way. As the valve is modularly constructed it allows an inexpensive mass production via injection molding, is easily adaptable to various applications and can be automatized mounted. Moreover it is uncomplicated to incorporate the valve into existing dosing systems without great effort. <br><br> For further information please see also the following link: http://www.process.vogel.de/index.cfm?pid=7085&pk=336319&print= (article in German)

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
