Abstract: A cutting device for cutting a pipe having a pipe wall. The cutting device includes an elongate carrier having a tool end which is engageable with a power tool and an opposed free end. The device includes a guide wheel located at the free end of the carrier which is loosely mounted thereon for rotation relative thereto, having a bearing surface extending parallel to a longitudinal axis of the carrier. The device also includes a cutting element having a peripheral cutting edge which is located adjacent to the guide wheel being positioned intermediate the guide wheel and the tool end. The cutting element is of greater transverse dimension than the guide wheel so that when the bearing surface bears against an internal surface of the pipe the distance between the cutting edge of the cutting element and the bearing surface enables the cutting element to cut through the pipe wall.

Abstract: A cover for an airbag device disposed on a supporting portion including an exit opening for an airbag, which is covered with a cover component. The cover includes a cover layer applied to the supporting portion and the cover component, the cover layer being weakened along a weakening line in or near a hinge region of the cover component.

Abstract: A process is disclosed for applying a heat shielding coating system on a metallic substrate. The coating system comprises at least three individual layers selected from the group of barrier layer, hot gas corrosion protection layer, protection layer, heat barrier layer, and smoothing layer. The coating system is applied to the metallic substrate by low pressure plasma spraying in a single operation cycle. This process enables the layers to be applied in an arbitrary sequence. The process is preferably used in applying a coating system to a turbine blade, particularly a stator or a rotor blade of a stationary gas turbine or of an aircraft engine, or to another component in a stationary or aircraft turbine that is subjected to hot gas.

Abstract: A method is proposed for coating a base body which has at lest one inner passage (101, 102), in which method the coating takes place by means of chemical deposition from the vapour phase, with the base body (10) being arranged on a holding device (3) in a reaction space (21) of a reactor vessel (2) with a process gas being delivered from an external source (7), the process gas being added to an internal generator (4) in the reaction container (2), in which the reactivity of the process gas is increased with the aid of a reactivity changing material and the process gas is conveyed out of the internal generator (4) into the reaction space (21). The process gas is sucked out of the reaction space (21) through the at least one inner passage (101, 102) and through the holding device (3) to an outlet (5) of the reactor vessel (2). Further an apparatus suitable for the method is proposed.

Abstract: According to a method for producing a solid ceramic fuel cell, a solid electrolyte layer is gas-tightly deposited on an electrode inside a coating chamber, using a plasma spraying technique. The pressure inside the coating chamber is set at less than approximately 15 mbar for this purpose. A coating material is powder form, preferably with a particle diameter of significantly less than 10 ?m, is finely dispersed in the plasma jet in such a way that the individual particles are isolated from each other when they meet the electrode. This enables a very homogenous and impervious solid electrolyte layer to be deposited.

Abstract: The plasma spraying method is a coating method in which a material to be coated is sprayed onto a surface of a metallic substrate (2) in the form of a powder beam. The coating material is injected at a low process pressure, which is lower than 10,000 Pa, into a plasma defocusing the powder beam and is there partly or fully melted. In this connection, a plasma with sufficiently high specific enthalpy is produced so that a substantial portion, amounting to at least 5% by weight, of the coating material changes into the vapour phase and an anisotropically structured coating (1) is produced on the substrate. An anisotropic structured layer of the coating material is deposited on the substrate. In this coating, elongate particles (10), which form an anisotropic micro-structure, are aligned standing largely perpendicular to the substrate surface and low-material transitional zones (11, 12) bound the particles from one another.

Abstract: A combination of a plasma spraying process and a vacuum slip casting process is carried out. By combining these two processes, which can each be carried out without difficulty, it is surprisingly possible to achieve good electrolyte layers. Therefore, it is possible to construct a fuel cell system using coated tubes in a bundled arrangement, the tubes being electrically connected in series and operated as a fuel cell generator in power units of between 100 kW and a few MW.

Abstract: An address match determining device has an address filter memory (22) for storing a matrix or table having a plurality of elements each of which is a 1-bit address match determination data indicating whether or not a corresponding N-bit address code is available, and is distinguished by a pair of a first index composed of the m most significant or high-order m bits of the corresponding address code and a second index composed of the remaining lowest or low-order (N−m) bits of the corresponding address code. A received-address latch (21) extracts the high-order m bits and remaining low-order (N−m) bits from an address code latched thereinto.
