Patent number: 6822193Abstract: The invention concerns a method for making Solid Oxide Fuel Cells (SOFC) and stacks. The method concerns assembling the layers required for the formation of a fuel cell, sintering the fuel cell and thereafter shaping the cell. When making a fuel cell stack, the sintered fuel cells are assembled with the interconnect, spacing and sealing material to form a stack of at least one stack element, followed by shaping the stack. Shaping is carried out in various ways and maximum tolerances of 1% are obtained.Type: GrantFiled: May 12, 2003Date of Patent: November 23, 2004Assignee: Haldor Topsoe A/SInventors: Christian Olsen, Jens Christiansen

Patent number: 6795462Abstract: The invention describes a gas laser comprising a container (6) intended to receive a gas or a gas mixture as laser-active medium, the container (6) having an axis (14) along which the gas laser emits its laser radiation, and comprising further means for generating a plasma in the container (6) and means for generating a magnetic field in the container (6). It is provided according to the invention that a group of at least two pairs of magnet poles is arranged, with the poles (1, 2) extending at a distance from, and along the axis (14) and being arranged around the axis (14) with alternating polarity so that the magnetic field emanating from them exhibits an intensity sink in the region of the axis (14), and that the means for generating the plasma include a source for an electromagnetic alternating field, which is associated to the container (6).Type: GrantFiled: April 12, 2002Date of Patent: September 21, 2004Inventors: Jens Christiansen, Kai Christiansen, Joachim Jacoby, Silke Christiansen

Patent number: 6243598Abstract: A method of preparing a rare earth-barium-cuprate superconductor in the form of metallic tapes or wires, using a thick film or powder-in-tube process by supporting on a metallic substrate a mixture of seed crystals or aligned platelets of rare earth-barium cuprate having a high melting point and rare earth-barium-cuprate powder having a lower melting point. The material supported on the substrate is then subjected to a heat treatment at a temperature below the melting point of the high melting rare earth-barium-cuprate seed crystals and the metallic substrate and above the melting point of the low melting powder. Subsequently, the heat treated supported material is cooled below the melting temperature of the material and annealed.Type: GrantFiled: March 12, 1998Date of Patent: June 5, 2001Assignee: Haldor Topsoe A/SInventor: Jens Christiansen

Patent number: 5091819Abstract: The switch has a gas discharge chamber, in which two electrodes, namely a cathode (11) and an anode (12), are contained, which are spaced a distance (d) apart and are separted from each order by an electrically insulating wall (9a) made of ceramic material or of glass. The cathode (11) is formed with a hole (5). The electrodes (11, 12) are joined to the insulating wall (9a) by a tight metal-ceramic joint or fused joint. The gas discharge chamber is filled with an ionizable low-pressure gas under such a pressure p that the product p.times.d has such a value that a gas discharge between the electrodes (11, 12) will be fired in response to a voltage applied thereof which is disposed in that branch of the firing voltage-pressure characteristic in which the firing voltage descreases as the pressure rises.Type: GrantFiled: February 23, 1989Date of Patent: February 25, 1992Inventors: Jens Christiansen, Klaus Frank, Werner Hartmann, Claudius Kozlik

Patent number: 4335465Abstract: An electron and ion accelerator includes plural spaced electrodes which are apertured to define a gas discharge path and supported at their peripheries by insulative means. A gas supply provides low pressure gas capable of producing electrons and ions in the gas discharge path. A voltage applied between the at least two electrodes establishes an electrical potential between them such that a spark-like gas discharge occurs along the gas discharge path. The current density obtainable in the low pressure gas is substantially higher than the density of an electron or ion flow in a vacuum.Type: GrantFiled: January 31, 1979Date of Patent: June 15, 1982Inventors: Jens Christiansen, Christoph Schultheiss
