    • A vacuum loader system is disclosed. In the vacuum loader system, the air inlet comprises a load-bearing member of a support structure that supports the system. The vacuum loader system also includes a filter chamber with co-located primary and secondary or safety filter elements. A safety filter element is at the center of the filter chamber, surrounded by primary filter elements. After the air flows through the primary and safety filter elements, it is directed downwardly, out of the filter chamber and back toward the blower, beyond which it is ultimately expelled through a silenced outlet. In some embodiments, the conduit that carries air from the filter chamber toward the blower may also be a member of the support structure.

    • A method and system for modeling of object-oriented database structures, translation to relational database structures, and dynamic searches thereon. The user may create, edit and manipulate a user's object database (dynamically translated into a set of relational database structures), to create, edit and manipulate objects for that object database (dynamically translated into data for those relational database structures), and to create, edit and manipulate queries to be applied to that object database (dynamically translated into queries to be applied to those relational database structures). A meta-model of the user's object database, which is itself an object database, and which has itself been translated into a set of relational database structures for manipulation by a relational database engine. The meta-model comprises a set of classes, objects, and relationships between classes which model the classes and relationships between classes of the system. Each of these classes may comprise a set of searchable properties, and each of these relationships may comprise an inheritance relationship (between a base class and a derived class) or a data-model relationship (such as a one-to-one, one-to-many, or many-to-many relationship). The data model of the user's object database is modeled by actual objects in the meta-model, and editing or manipulating the user's object database is modeled by creating, modifying, or deleting objects in the meta-model. The meta-model also models itself, in the same manner as it models the user's object database, and may be manipulated in the same manner as the user's object database.
    • 一种用于面向对象数据库结构建模,关系数据库结构转换和动态搜索的方法和系统。 用户可以创建,编辑和操纵用户的对象数据库(动态转换为一组关系数据库结构),以创建,编辑和操作该对象数据库的对象(动态转换为这些关系数据库结构的数据),并创建 ,编辑和操纵要应用于该对象数据库的查询(动态转换为要应用于这些关系数据库结构的查询)。 用户对象数据库的元模型,其本身是对象数据库,并且其本身已经被转​​换成关系数据库结构的集合以供关系数据库引擎操纵。 元模型包括一组类,对象和类之间的关系,它们对类和类之间的关系进行建模。 这些类中的每一个可以包括一组可搜索的属性,并且这些关系中的每一个可以包括继承关系(在基类和派生类之间)或数据模型关系(诸如一对一, 多对多或多对多关系)。 用户对象数据库的数据模型由元模型中的实际对象建模,并且通过在元模型中创建,修改或删除对象来对编辑或操纵用户对象数据库进行建模。 元模型还以与模拟用户对象数据库相同的方式对自身进行建模,并且可以以与用户对象数据库相同的方式进行操作。
