20150122653 | Method for the Separation of Polarizable Bioparticles - The invention relates to a method for the separation of a polarisable bioparticle comprising the steps: a) dielectrophoretic preseparation of a polarisable bioparticle from a suspension of bioparticles; b) fluidic separation of the selected bioparticle by fixing the bioparticle in a dielectrophoretic field cage and circulating fluid around the bioparticle; c) transferring the separated bioparticle from the dielectrophoretic field cage to a culture chamber; d) dielectrophoretic fixing of the separated bioparticle in the culture chamber and study, observation, manipulation and/or culturing of the separated bioparticle. The invention further relates to a microfluidic system and use thereof. | 05-07-2015 |

20160001800 | RAIL VEHICLE COMPRISING A TACHOMETER-SPEED DISPLAY DEVICE, AND A METHOD FOR OPERATING SUCH A RAIL VEHICLE - A rail vehicle has a tachometer-speed display device and an European train control system speed display device. In order to easily avoid the speed being read incorrectly by the vehicle driver in such a rail vehicle, the glass cover of the tachometer-speed display device is an electro chrome glass pane that contains an electrical connection device. A method also operates a rail vehicle which contains such a tachometer-speed display device. | 01-07-2016 |

20150322543 | APPARATUS AND METHOD FOR PRIMING A MOLTEN METAL FILTER - An apparatus and method are described for effectively priming a non-electrically conductive filter for removal of solid inclusions from liquid metal. In one embodiment, the ceramic filter media is surrounded by a low frequency induction coil (1-60 Hz) with its axis aligned in the direction of the net metal flow. The coil is positioned to enhance the heating of any metal frozen onto, or in the pores of the filter element. In one embodiment, the coil is positioned in order to generate Lorentz forces, which act to cause heated metal to impinge on the upper surface of the filter element, enhancing the priming action. Once a filter equipped with such a coil has been primed, it can be kept hot or reheated, and subsequently reused during several batch tapping sequences. | 11-12-2015 |
