20110137252 | DEVICE FOR PROVIDING A PERCUTANEOUS ENDOSCOPIC GASTROSTOMY - The device according to the invention for providing a percutaneous endoscopic gastrostomy (PEG) comprises a handle for handling the device. The wire that is to be inserted into the stomach of the patient is rolled on a wire spool that is mounted either in a rotatable manner on the handle part or on an attachment piece that can be attached to the handle. Aside from the puncturing cannula for puncturing the stomach, the device according to the invention comprises an insertion cannula for insertion the wire rolled on the wire spool into the stomach. The device according to the invention is characterized in that the puncturing cannula is designed as an outer cannula surrounding the insertion cannula, while the insertion cannula is designed as an inner cannula surrounded by the puncturing cannula, wherein the insertion cannula is guided into the puncturing cannula in a longitudinally displaceable manner. During the puncture of the stomach, the insertion cannula is recessed into the puncturing cannula. The design of the insertion cannula as an inner cannula and the puncturing cannula as an outer cannula provides the advantage that the puncture can be carried out only with the puncturing cannula. The design problem of an even transition between an insertion cannula as an outer cannula and a puncturing cannula as an inner cannula is solved by the device according to the invention. Moreover, puncturing and insertion cannulas made of steel can be produced with a comparable low technical effort and relatively low costs in great numbers without the need for both cannulas to be formed to each other for achieving a smooth transition. | 06-09-2011 |

20130309524 | POLYCRYSTALLINE SILICON - Polycrystalline silicon in the form of chunks packed in plastic bags containing a mass of at least 5 kg, including chunks of size from 20 to 200 mm, wherein any fines fraction in the plastic bag is less than 900 ppmw, preferably less than 300 ppmw, more preferably less than 10 ppmw. The polycrystalline silicon, after comminution of a silicon rod obtained by CVD (Siemens process), is sorted and classified, optionally dedusted and then metered and packed. Metering and packing units include elements for removing fines or small particles during metering and during packing. The packing unit includes an energy absorber or a reservoir vessel which enables sliding or slipping of the silicon chunks into the plastic bag. Gas flow generated within the plastic bag after the bag has been filled transports the dust or small particles out of the bag, and these are sucked out with a suction device. | 11-21-2013 |
20140165503 | PACKING POLYCRYSTALLINE SILICON - The present invention relates to a method for packing polysilicon in the form of chunks by introducing the chunks into a first plastic bag, the first plastic bag being introduced into a second plastic bag after the introduction of the chunks, or the first plastic bag already having been inserted into the second plastic bag prior to the introduction of the chunks into the first plastic bag, as a result of which the chunks are present in a double bag which is sealed, wherein the air present in the two plastic bags in the double bag after the introduction of the chunks is removed before the sealing of the double bag such that the total volume of the double bag relative to the volume of the chunks is 2.4 to 3.0. | 06-19-2014 |
20140314654 | POLYCRYSTALLINE SILICON ROD AND METHOD FOR PRODUCING POLYSILICON - Polycrystalline silicon rods produced by the Siemens process produce a higher yield of CZ crystals when the process parameters are modified in a second stage of deposition such that an outer layer of larger crystallites having a mean swize>20 μm is produced. Harvesting of these polycrystalline rods and conventional rods by enclosing them in a plastic bag or sheath prior to removal from the reactor also surprisingly increase the yield of CZ crystals grown from a melt containing the sheathed rods. | 10-23-2014 |
