  • Patent number: 7994540
    Abstract: Gallium nitride material transistors and methods associated with the same are provided. The transistors may be used in power applications by amplifying an input signal to produce an output signal having increased power. The transistors may be designed to transmit the majority of the output signal within a specific transmission channel (defined in terms of frequency), while minimizing transmission in adjacent channels. This ability gives the transistors excellent linearity which results in high signal quality and limits errors in transmitted data. The transistors may be designed to achieve low ACPR values (a measure of excellent linearity), while still operating at high drain efficiencies and/or high output powers. Such properties enable the transistors to be used in RF power applications including third generation (3G) power applications based on W-CDMA modulation.

  • Patent number: 5911981
    Abstract: Surfactant blends that generate a stable spherical foam are disclosed. The surfactant blends contain a nonionic surfactant or an amphoteric surfactant as the principal foaming agent, and a sufficient amount of an acylate lactylate to enhance foam volume and provide a foam that remains in a spherical form for up to about forty minutes. A method of generating a long-lasting foam also is disclosed.

  • Patent number: 4490593
    Abstract: Arc control in a high amperage molded case circuit breaker is provided by a steel horn for each of a plurality of contact blades for each phase. The horn has a portion extending into a U-shaped recess in a steel arc runner plate. As the contacts separate, the portion travels close to one wall of the recess and then close to the other wall to transfer the arc from the contacts first to the one wall and then to the other wall which is located adjacent the arc suppressor assembly. A respective adjustment member extending through each horn controls the spacing between the blades and a contact carrier to in turn control the opening sequence of the contacts for minimizing arcing across certain contacts. Arc suppressor plates of alternating length are arranged in an arc corresponding to blade travel and define passageways having their larger exits aligned with respective vents defined by a molded insulator engaged in the wall of the base.
