Abstract: A method of manufacturing a bonded substrate stack includes: providing a first substrate having a first hybrid interface layer, the first hybrid interface layer including a first insulator and a first metal; and providing a second substrate having a second hybrid interface layer, the second hybrid interface layer including a second insulator and a second metal. The hybrid interface layers are surface-activated to generate dangling bonds on the hybrid interface layers. The surface-activated hybrid interface layers are brought into contact, such that the dangling bonds of the first hybrid interface layer and the dangling bonds of the second hybrid interface layer bond together to form first insulator to second insulator bonds and first metal to second metal bonds.

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.

Abstract: The invention relates to a refractory ceramic plate and an accompanying wall structure for an incinerator, for example a garbage incinerator.

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.

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.

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.
