  • Web-based method and system for identifying and searching patents
    Publication number: 20020169743
    Abstract: A web-based method of obtaining recorded information based on a pre-defined search criteria includes the steps of receiving search criteria from a user through pull down menus, accessing a centralized database of recorded information, wherein the recorded information is linked to at least one identifier such as an identifier number, and comparing the search criteria with information in the database using identifiers to retrieve the requested information. Boolean logic operators are used to define logical relationships among various search criteria to conduct a more focused search and scheduled searching is used to provide updates of recently published recorded information.

  • Circuit breaker mechanism for a contact system
    Patent number: 6369340
    Abstract: A rotary contact circuit breaker employs a crank to couple a switching mechanism to the rotary contact pole structure. The use of a crank allows for the mechanism and pole structure the individually optimized without effecting the performance of the other. In particular the crank allows for a mechanism that is able to achieve maximum torque delivery to the pole structure.
