Abstract: Method and apparatus for registering and bonding upper and lower substrate plates together through a sealer material and in such a way as to form a gap of a predetermined width between the two substrate plates. Registered substrate plates are provisionally pressed to form a joined substrate assembly, which is then pressed under heated conditions at a hot press station, thereby compressing the sealer material into a flattened form and at the same time thermally hardening the sealer material to form a predetermined gap space between the two substrate plates. In order to correct positional deviations which occur to the upper and lower substrate plates in the course of the hot pressing, on the basis detected positional deviations of upper and lower substrate plates of a hot-pressed substrate assembly, upper and lower substrates are set in offset positions instead of aligned positions when registering them at the provisional press station to cancel predicted positional deviations at the hot press station.

Abstract: A computer-implemented system determines, by logical progression through multiple analysis levels, a human factor that represents a root cause of a particular incident. The system begins at a broad analysis level and progresses through more narrow analysis levels to a root cause level. Each analysis level includes multiple causal factor categories, with each causal factor category branching into causal factor subcategories that reside on a more narrow analysis level. The system includes an information input device for inputting incident information relating to the particular incident. The system also includes a memory device for storing a causal information database that provides a relationship between the multiple analysis levels and causal factor categories and between causal factor categories and root causes. The causal information database also relates root causes to corrective actions that may be implemented to prevent future occurrences of the incidents.

Abstract: In a filter plate-and-diaphragm assembly for a filter press, which assembly includes a filter plate having a depressed base and a thickened marginal region defining a circumferential sealing edge, and a pressure diaphragm disposed at each side of the plate and having a cup shape to conform to the depressed base of the plate, the, or each, diaphragm is provided with a foldable tongue extending at least over the sealing edge along one side of the plate and securing the diaphragm to at least one lateral edge face of the plate.
