Abstract: A data structure and application programming interface for creating and manipulating object model artifacts within a meta-model is provided. The data structure may include higher level abstractions of the type system to provide a set of services to implement software design tools and editors.

Abstract: The present invention relates to a system and methodology providing an Application Programming Interface (API) and framework that supports a meta-object model for application design and operating system interactions. The API includes an input component that receives data and/or instructions. The input component processes a meta-data model that interrelates data via a class hierarchy, wherein the class hierarchy includes relationship descriptions between class objects, attributes, rules, and/or behavioral descriptions. Another aspect includes a data management system that includes a component to receive an item having meta-data annotations. An analysis component determines at runtime a structure for the item via deployment of the meta-data annotations. The system can also include a framework component that defines meta-data class derivations, meta-data classes, meta-data integrity rules, and/or meta-data class behavior.

Abstract: A plate heat exchanger assembly having a plurality of corrugated metal members between two end cover metal members and interspaced with gasket members. The corrugated metal members have corrugations establishing a network of contact points and forming turbulent channels for heat exchange between two fluids flowing counter-currently in and out through at least four ports. Each of the corrugated metal members, end cover metal members and gasket members have at least four corner portholes in alignment with corresponding portholes. Each gasket member has two through portholes and two communicating portholes. Clamping means pass through each aligned porthole for clamping each of the four ports on either side of the plate heat exchanger assembly to bind individual ports.
