    • The air release valve comprises a valve chamber (36) having an inlet (20) and an outlet (24). Inside the chamber is a control float (38) which is responsive to changes in liquid level in the chamber. There is also a a stack of valve members (40, 42, 44) in the chamber above the control float. The valve members have vent passages through them which increase in size with increasing height in the stack but which are smaller than the outlet (24). The top valve member (44) in the stack is designed to be lifted up, by differential air pressures acting on it, to seat on the outlet (24) and thereby reduce the effective size of the outlet when a pipeline served by the air release valve is filling with liquid and the liquid displaces air through the valve.

    • Techniques for visual data import into an object model are described. A graphical user interface concurrently displays a first icon that represents a first object type and a second icon that represents a second object type. Input defining object-to-data mappings between properties of the object types and structured data of one or more data sources is received. Further input defining a relationship type for relationships between the first object type and the second object type is also received. In response to the second input, a graphical representation of the relationship type is displayed, visually linking the first icon to the second icon. Based at least on the object-to-data mappings, the definition of the relationship type, and the structured data, an object model is created, comprising first objects of the first object type, second objects of the second object type, and relationships between the first objects and the second objects.
    • 描述可视化数据导入对象模型的技术。 图形用户界面同时显示表示第一对象类型的第一图标和表示第二对象类型的第二图标。 接收在一个或多个数据源的对象类型和结构化数据的属性之间定义对象到数据映射的输入。 还接收定义第一对象类型和第二对象类型之间的关系的关系类型的进一步输入。 响应于第二输入,显示关系类型的图形表示,将第一图标视觉上链接到第二图标。 至少基于对象到数据映射,关系类型的定义和结构化数据,创建对象模型,包括第一对象类型的第一对象,第二对象类型的第二对象以及第二对象类型之间的关系 第一个对象和第二个对象。
