  • Patent number: 6487980
    Abstract: A refractory ceramic plate and an accompanying wall structure for an incinerator, such as a garbage incinerator. The refractory ceramic plate has at least two recesses arranged on a main surface of the plate, wherein a blind hole runs from each recess to the interior of the plate. The wall structure features a furnace wall, in which numerous pipes spaced apart from each other, through which a fluid can flow, are arranged. Anchors are secured to sections of the furnace wall with one end, and project essentially perpendicularly from the furnace wall. A hollow space is formed between the furnace wall and the refractory ceramic plates spaced parallel apart from the furnace wall. Joints are formed between boundary regions of the refractory ceramic plates on main surfaces thereof, facing the furnace wall. The anchors lie in the joints, with free ends embedded in a heat-resistant filling. A heat-resistant, deformable compensating layer is provided in the joint area between adjacent plates.

  • Patent number: 5855959
    Abstract: A process for depositing catalytically active platinum metal layers from an ionogenic, acidic, platinum metal ions-containing solution which further contains sulfonic acid. This activation leads to more uniform catalyst layers with greater surfaces which are catalytically more efficient. The process according to the invention can be implemented in any chemical process utilizing platinum metal catalysts, e.g. chemical synthesis, environment applications or metallization of surfaces.

  • Patent number: 4762689
    Abstract: A mounting frame for a block-type parallel mounting of catalyst plates is provided. The block mounting has frame members separated by a distance substantially corresponding to the width of the catalyst plates to be mounted. The frame members are provided with a series of guide slots open on top for admission of the catalyst plates. On the bottom edges of the frame members, there are provided base supports for the bottom edges of the catalyst plates. The frame members themselves also form lateral supports for the catalyst plates to prevent movement thereof when mounted in the module. The mounting modules, once loaded with the planar elements, can be combined into a larger frame in a horizontal mode, or they can be vertically stacked, such as in the flue of a combustion furnace itself. The plates are typically pre-coated with a material that is catalytic to further the conversion of the gaseous compounds passing thereby.

  • Patent number: 4728128
    Abstract: A connection assembly for joining two parts having confronting ends with a joint therebetween, particularly ceramic pipes, includes a dimensionally stable coupling member surrounding the joint and at least one of the two confronting ends of the two parts to be joined. The coupling member is dimensioned to define a space with the at least one part end. This space is filled with a ceramic fiber mat material containing a swelling agent capable of volume expansion when subjected to a temperature above a given minimum temperature. As a result, upon being subjected to an operating temperature above such given temperature, the swelling agent swells the ceramic fiber mat material, such that the mat material is compressed between the coupling member and the at least one part end surrounded thereby, thereby connecting the two parts.

  • Patent number: 4444242
    Abstract: A modular shutter is assembled of prefabricated components and of yard goods or piece goods which are cut to size at the locale of use. The components of the shutter include two upright guide rails for the end portions of a curtain of upwardly and downwardly movable as well as tiltable slats, a horizontal main shaft between the upper end portions of the guide rails, a housing mounted on top of each guide rail and having bearings for the corresponding end portions of the main shaft, a motor or a crank drive for rotating the main shaft clockwise or counterclockwise, and combined lifting and tilting mechanisms in the housings. Such mechanisms have lifting bands which are connected with the end portions of the slats to effect upward or downward movements of the slats in response to rotation of the main shaft in one or the other direction, and tilting bands which change the angular positions of the slats in response to selected rotation of the main shaft.

  • Patent number: 4444241
    Abstract: A blind or shutter which is or can be assembled of prefabricated components and of yard goods cut to size at the locale of use has two hollow upright guide rails for the end portions of a curtain of interconnected upwardly and downwardly movable as well as tiltable slats, and combined lifting and tilting mechanisms for the slats. Such mechanisms have lifting bands which are disposed in the guide rails and are connected with the end portions of the slats to effect upward or downward movements of the slats in response to rotation of a main shaft in one or the other direction, and tilting bands which are disposed in the guide rails and change the angular positions of the slats in response to rotation of the main shaft. Blocking levers in the guide rails are connected with the ends of the lowermost slat by vertically movable carriages and engage the respective guide rails by gravity to hold the lowermost slat against unauthorized lifting when the lifting bands are slack.
