摘要:
An improved ball controlled float control unit wherein a slotted raceway housing pivotally accomodates a narrow ball cage within the slot and with the ball cage being in constant contact with said ball while the ball is permitted to be rollingly supported by the edges defining the slot, with the ball being precluded from getting out of or behind the ball cage, thereby eliminating any possibility of the ball locking up the control function of the unit.
摘要:
The present invention generally is directed to methods, articles of manufacture and systems for automatically generating abstract representations of a limited subset of data repository fields accessed by a particular application. The limited subset of fields may be identified by monitoring queries issued against the data repository by the application. The abstract representations may be grouped in a data repository abstraction (DRA) component that serves as a data definition framework allowing data from the fields to be accessed independent of the particular in which the data is physically represented in the data repository. By limiting the fields exposed to the application to the limited subset of fields actually accessed by the application, the DRA component, in effect, provides the application with a custom database tailored to its particular needs.
摘要:
A system, method and article of manufacture for query execution management in a data processing system and more particularly for scheduling execution of queries against one or more databases in a data processing system. One embodiment provides a method for managing query execution in a data processing system. The method comprises providing at least one query execution schedule configured to schedule specific queries against a database in the data processing system, receiving a query against the database, and managing execution of the received query on the basis of the at least one query execution schedule.
摘要:
Methods, articles of manufacture, and systems for searching collections of data using context sensitive expanded term searching using dynamic term expansion are provided. The collection of data may be a relational database, text document, or any other type of searchable collection of data. In either case, a query including a search condition based on a specified search term may be modified to include additional conditions based on a set of expanded (e.g., conceptually-related) search terms dynamically linked with the query. For some embodiments, a user may be given the ability to choose whether the set of expanded search terms are dynamically linked with the query or not.

摘要:
The present invention generally is directed to a system, method and article of manufacture for accessing data independent of the particular manner in which the data is physically represented. In one embodiment, a data repository abstraction layer provides a logical view of the underlying data repository that is independent of the particular manner of data representation. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs translation of an abstract query into a form that can be used against a particular physical data representation.
摘要:
Methods, systems and articles of manufacture are provided for query evaluation. The query is evaluated upon inputting each incremental query element (or combination of element). Generally, for each incremental query element added, a query performance analysis is performed with respect to one or more runtime metrics such as total execution time and runtime resource consumption. The results of the analysis are provided as feedback to the user constructing the query.

摘要:
A furnace for treating metal parts includes a treatment atmosphere provided at an interior of the furnace; at least one burner operatively associated with the furnace for heating the treatment atmosphere to a temperature below a melting point of the metal parts; a passageway interconnecting the interior and the at least one burner, the passageway directing at least a portion of the heat treatment atmosphere exhausted from the furnace interior to the at least one burner for combustion; and a source of oxygen in fluid communication with the at least one burner for enriching combustion of the heat treatment atmosphere portion with oxygen at said burner. A related method is also provided.
