  • Patent number: 7246556
    Abstract: A case for multiple stamp pads is provided. One embodiment of the case includes a first housing portion for retaining a first stamp pad, a second housing portion for retaining a second stamp pad, a hinge connecting the first and second housing portions for movement between a closed configuration where the first and second stamp pads are facing each other and sealed within the first and second housing portions and an open configuration where the first and second stamp pads are exposed for use, and a divider separating the first and second stamp pads in the closed configuration and swingably covering one of the first and second stamp pads in the open configuration.

  • Patent number: 6897309
    Abstract: This invention describes a process for preparing hydroxyazapirones of Formula I from azapirones of Formula II. The process comprises treating azapirones with a strong base, monitoring enolate formation of the azapirone by IR spectroscopy, and reacting the enolate with a source of molecular oxygen in the presence of a reductant. The process is suitable for large scale production of hydroxyazapirones.

  • Publication number: 20030141589
    Abstract: An apparatus for processing a high-frequency electrical signal. The apparatus comprises a circuit carrier and an electrical circuit mounted on the circuit carrier. The electrical circuit processes a signal within a predetermined frequency range, the predetermined fundamental frequency range having a low end in the range being about 1 GHz or higher. An encapsulent material encapsulates at least a portion of the electrical circuit. The circuit carrier, electrical circuit, and encapsulent material form a package having resonant frequencies. The resonant frequencies are outside the predetermined frequency range.
