  • Patent number: 8635233
    Abstract: Techniques to automatically build a language dependency graph for localizable resources are described. A technique may include storing resources from a file in a translation database with data that indicates the language that the resource is in, the entity that created that version of the resource, and a dependency, if any, on a different language version of the resource. Subsequent translations of a resource may also be stored in the translation database in a manner that groups the translated version(s) of a resource to the original resource, and also stores the language of the resource, the entity that translated it, and the dependency to the language from which the resource was translated. A language dependency graph may be generated from the translation database for a file, where the graph reflects the languages of translation and dependency relationships among the translations. Other embodiments are described and claimed.

  • Patent number: 8348237
    Abstract: In pneumatic non-load quick dual-speed hydraulic jack, the small of piston ring (17) of hydraulic pump cylinder integrates with pump body (19) and external ring of step pump core (14) to form movable assembly. The middle part of step pump core (14) is provided with pump core step interface (8) used for conversion of hydraulic speed. The step hole on the same axis of pneumatic valve block on special pneumatic valve structure is provided with washer (48), button (49), pneumatic valve core (45), compressed spring (68) and valve core fastness set. The pneumatic valve parts can replace the hydraulic quick pump structure partially when the high-pressure air source is available. High-pressure air delivered to the oil reservoir of the external sleeve (4) presses the hydraulic oil into the oil chamber of oil cylinder, and thus facilitates the quick lift of jack piston under light load or empty load.
