    摘要: There is provided a heat exchanger system comprising a housing defining a heat exchange compartment in which are extending a plurality of circular flexible pipes including radially extending fins, the fins defining a helical pattern along the length of each of the circular flexible pipes. There is also provided a circular flexible pipe having radially extending fins, the fins defining a helical pattern along the length of the circular flexible pipe. There is further provided a method and an apparatus for manufacturing a circular flexible pipe having radially extending fins, the fins defining a helical pattern along the length of the circular flexible pipe.

    摘要: A computer-implemented information analysis and display system, called a linguistic filter, and method is provided to dynamically generate and display topics representing the linguistic content of documents in a file system. The documents may be user-selected. Also, the user operates a user computer to select one or more of such dynamically generated and displayed topics, preferably using a graphical user interface. The linguistic filter displays document identifiers corresponding to those documents that are described by one or more of the topics selected by the user. The file system may be local, or remote, or both. A user may select for display only those topics representing the linguistic content of documents that are written in one or more user-selected natural languages. Also, topics of documents written in a natural language may be displayed in relation to such natural language. The linguistic filter displays a graphical user interface including a document window and a topic tree window. In some implementations, the document window includes document identifiers and associated lists of topics representing the linguistic content of the documents represented by the document identifiers. In some implementations, the topic tree window includes a hierarchical representation including a collapsible and expandible, tree-like graphical structure of topics. Such hierarchical representation is typically a single merged representation of topics that represents the linguistic content of the user-selected documents taken as a whole. Alternatively, such hierarchical representation is a single merged representation of topics that represents the linguistic content of the associated lists of topics as a whole. A user may display the text of one or more documents by selecting one or more document identifiers in the document window, or one or more topics in the topic tree window. If the user selects one or more topics from the list of topics in a document entry in the document window, or from the topics in the topic tree window, the texts of the document or documents corresponding to such selected topic or topics are displayed, and the grammatical units corresponding to the selected topic or topics are highlighted.
