20080202484 | Ignition coil for an internal combustion engine - An ignition coil for an internal combustion engine has a core, which is provided with a plastic extrusion coat on its periphery. The core is concentrically surrounded by a secondary coil and a primary coil. The plastic extrusion coat of the core is used as a coil shell for the secondary coil so that it is possible to dispense with a separate secondary coil shell. The ignition coil therefore has an especially compact design. | 08-28-2008 |
20100018033 | Method For Producing a Coil, in Particular an Ignition Coil For a Motor Vehicle - A method for producing a coil, in particular an ignition coil for a motor vehicle, in which a primary winding is wound onto a winding mandrel. Then the winding mandrel is introduced into a housing of the coil and the winding mandrel then is removed from the housing, the primary winding remaining inside the housing. Finally, additional components of the coil, in particular a secondary coil shell onto which a secondary winding has been wound, are introduced into the housing, so that the secondary winding is concentrically disposed within the primary winding while dispensing with a separate primary coil shell. The method allows a design of the coil that is more compact in diameter. | 01-28-2010 |
20150247071 | Adhesive bonding by polymer chain reconfiguration - A method is described for joining, in particular adhering, plastic to a substrate. To achieve a strong adhesive effect, in a method task a) a plastic material that encompasses at least one thermally reversibly cleavable polymer is furnished, and in a method task b) the plastic material is brought into contact with the substrate, a portion of the plastic material which is brought into contact with the substrate being heated to a temperature at which the at least one thermally reversibly cleavable polymer of the plastic material becomes thermally cleaved, and re-cooling or being re-cooled while in contact with the substrate. Also described is a plastic/substrate composite manufactured thereby, a polymer, and a polymer use for adhering. | 09-03-2015 |

20090042080 | Porous Body and Production Method - A porous body which has a density of from 40 to 70%, is formed from an Fe-based alloy and contains from 0.01 to 2% by weight of mixed oxide with at least one oxidic compound of one or more metals from the group consisting of Y, Sc, rare earth metals and at least one further oxidic compound of one or more metals from the group consisting of Ti, Al, Cr. The porous body displays no after-shrinkage even at operating temperatures of 900° C., it has very good corrosion resistance and it is particularly suitable as a support substrate for use in high-temperature fuel cells. | 02-12-2009 |
20100316193 | X-RAY ANODE HAVING IMPROVED HEAT REMOVAL - An X-ray anode includes a coating and a support body. In addition to a strength-imparting region, the support body has a region formed of a diamond-metal composite material. The diamond-metal composite material is formed of 40 to 90% by volume diamond particles, 10 to 60% by volume binding phase(s) formed of a metal or an alloy of the metals of the group consisting of Cu, Ag, Al and at least one carbide of the elements of the group consisting of Tr, Zr, Hf, V, Nb, Ta, Cr, Mo, W, B, and Si. The highly heat-conductive region can be form-lockingly connected at the back to a heat-dissipating region, for example formed of Cu or a Cu alloy. The X-ray anode has improved heat dissipation and lower composite stress. | 12-16-2010 |
20120163549 | ROTARY ANODE FOR A ROTARY ANODE X-RAY TUBE AND METHOD FOR MANUFACTURING A ROTARY ANODE - A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well. | 06-28-2012 |
20120189484 | Process for Producing an Interconnector of a High-Temperature Fuel Cell - A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value. | 07-26-2012 |
20130308758 | ROTARY X-RAY ANODE - A rotary X-ray anode has a support body and a focal track formed on the support body. The support body and the focal track are produced as a composite by powder metallurgy. The support body is formed from molybdenum or a molybdenum-based alloy and the focal track is formed from tungsten or a tungsten-based alloy. Here, in the conclusively heat-treated rotary X-ray anode, at least one portion of the focal track is located in a non-recrystallized and/or in a partially recrystallized structure. | 11-21-2013 |
20140334606 | PROCESS FOR PRODUCING A HIGH-TEMPERATURE-RESISTANT COMPOSITE BODY - A high-temperature-resistant composite body is formed by joining over an area of a first, nonmetallic section via a bonding solder layer to a second, metallic section composed of Mo, an Mo-based alloy, W or a W-based alloy. A first arrangement composed of the first section, a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement of the resulting partial composite body, a second solder adjoining the intermediate layer and the second section is subsequently soldered together in a second soldering step. The intermediate layer at least 90 atom % of at least one of the elements Ta, Nb, W. The second solder is formed by precisely one material selected from Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and it melts at a lower temperature than the first Zr solder in the second arrangement. | 11-13-2014 |
