  • Thermal bridge for connecting sections with a large temperature differential under high-pressure conditions
    Patent number: 11174754
    Abstract: A thermal bridge forms a connection between a cold side and a hot side that is capable of withstanding a large temperature differential while high-pressure gas (e.g., air) flows between the two sides within an internal passageway. A cold-side region and hot-side region of the thermal bridge may each have a flange with a plurality of holes. The cold-side region may also include a conical fillet with counterbore recesses to provide access to each of the plurality of holes from a low radial position.

  • Device for tattooing and method of using the same
    Patent number: 7748294
    Abstract: The present invention relates to a tattoo device having a single DC coil with a pulse width modulation (PWM) circuit to control when the single DC coil is energized. Such arrangement eliminates the need for a set screw as in traditional tattoo machines and allows for a lighter device having fewer vibrations, better balance, and improved precision when being used.
