20110056758	ELECTROCHEMICAL ACCUMULATOR AND VEHICLE COMPRISING AN ELECTROCHEMICAL ACCUMULATOR - An electrochemical accumulator includes a plurality of electrochemical cells, each of which has a casing. The accumulator also includes a cover, a housing which is closed by the cover, an electrolyte in the housing, and at least one connecting pole for making electrical contact with the accumulator, where the connecting pole is electrically connected to a group of the electrochemical cells. The accumulator also includes a cooling air area for holding cooling air for cooling the cells and a degassing area for holding a gas which emerges from the cells in the event of a defect. The cooling air area and the degassing area are separated from one another in a gas-tight manner and the cooling air area and the degassing area are passed out of the housing independently of one another. The cooling air area has channels which are guided on the casings of the cells outside the cells.	03-10-2011

20120085633	DRIVE MECHANISM FOR ELECTRIC SWITCHING DEVICES HAVING THREE SEPARATE POSITIONS - A switching device assembly has an encapsulation housing. Movable active conductors are located inside the encapsulation housing. A drive unit with a gearbox is located outside of the encapsulation housing. The gearbox is part of a kinematic chain for moving an active conductor. The kinematic chain penetrates the encapsulation housing. In order to reverse the direction of a movement of the gearbox that can be transmitted, the gearbox is turned around a reversing axis and coupled into the kinematic chain.	04-12-2012

20090104301	DEVICE FOR MELT SPINNING OF A LINEAR FILAMENT BUNDLE - A device for melt spinning a linear filament bundle has a spinning shaft for mounting a longitudinal spinning nozzle group, having a nozzle plate including a plurality of nozzle openings on a bottom, and an inlet plate having at least one inlet channel on a top. A distribution chamber is provided between the inlet plate and the nozzle plate, which is connected to the inlet channel in the inlet plate and the nozzle openings in the nozzle plate. The inlet plate has multiple inlet channels provided at a distance to one another in longitudinal direction of the spinning shaft. Multiple distribution chambers arranged next to one another are provided in longitudinal direction of the spinning shaft. The inlet channels each end in one of the distribution chambers.	04-23-2009
20100015266	DEVICE FOR MELT-SPINNING SYNTHETIC FILAMENTS - A device for melt-spinning synthetic filaments includes a spin-die manifold for holding at least one bank of spinnerets and heating device for heating the bank of spinnerets. At least one spinneret with second heating device for heating the spinning pump is allocated to the bank of spinnerets and the spinning pump and bank of spinnerets are interconnected by a melt line. To achieve a user-friendly arrangement for the bank of spinnerets and the spinning pump, the pump and the second heating device are held by a separate pump support which is placed at a distance from the spin-die manifold. This allows the spinning pump to be heated independently of the spin-die manifold.	01-21-2010
20110059196	DEVICE FOR MELT SPINNING MULTICOMPONENT FIBERS - A device for melt spinning multi-component fibers including at least two melt inlets for introducing separately guided melt components is presented. The device includes a feed plate having a plurality of feed channels for distributing the melt components, a distributor block associated with the feed plate, and a nozzle plate adjoining the distributor block and including a plurality of nozzle bores, wherein the distributor block has several thin distributor plates stacked on top of each other and each have a hole pattern with multiple distribution openings. The thin distributor plates are configured inside the distributor block such that a plurality of melt channels form, which connect the feed channels of the feed plate to the nozzle bores of the nozzle plate. In order to implement high flow volumes, multiple distributor plates having identical hole patterns of the distribution openings are stacked in a tightly sealing manner inside the distributor block.	03-10-2011
