摘要： Crystalline aluminophosphates and related compounds having in the as-synthesized anhydrous form the chemical composition: m'R(X.sub.n Al.sub.q P.sub.x)O.sub.2, wherein R represents 1,3-diaminopropane, X represents one or more elements which can be substituted for Al and/or P, whereinm'=0.01-0.33n=0-0.40q=0.30-0.60x=0.30-0.60and wherein n+q+x=1 and having an X-ray diffraction pattern containing at least the lines as given in Table A or B.The compounds can be prepared from a forming solution or gel comprising a source of aluminum, a source of phosphorus, 1,3-diaminopropane and optionally a source of at least one component X, wherein the appropriate forming components are initially present in certain molar ratios and which mixture is kept at elevated temperature for a period of time sufficient to produce a crystalline aluminophosphate or related compounds.

摘要： Crystalline aluminophosphates and related compounds having in the as-synthesized anhydrous form the chemical composition: m.sup.1 R(Al.sub.q P.sub.x)O.sub.2, wherein R represents ethylenediamine, whereinm.sup.1 =0.01-0.33q=0.30-0.60x=0.30-0.60and wherein q+x=1 and which have a distinct X-ray diffraction pattern.The compounds can be prepared from a forming solution or gel comprising a source of aluminum, a source of phosphorus, a source of ethylenediamine and optionally a source of at least one component X, wherein the appropriate forming components are initially present in specific molar ratios and which mixture is kept at elevated temperature for a period of time sufficient to produce a crystalline aluminophosphate or related compound followed by separating off the crystalline product obtained and drying, and which may subsequently be calcined.

摘要： A general purpose pattern recognition method and apparatus comprises a hierarchical network of basic recognizers, each basic recognizer being capable of discriminating a particular feature at a lower level and providing outputs for higher levels of abstraction. In a learning mode, a series of sample patterns having a feature are presented as input along with several near-miss patterns. The pattern recognition apparatus learns to recognize the feature by keeping track of which basic recognizers detect patterns containing the feature. In a recognition mode, the invention determines if a presented pattern has the feature by polling the basic recognizers. A summation algorithm calculates the likelihood that the presented pattern has a particular feature.
