  • Exhaust assembly temperature regulation
    Patent number: 11105249
    Abstract: An exhaust assembly includes an exhaust tube and a coolant passage. The exhaust tube is oriented about an axis and an exhaust gas is configured to flow through the exhaust tube in a direction away from an end of the exhaust tube. The coolant passage is oriented about the axis radially outward of the exhaust tube, the coolant passage having an inner shell and an outer shell. The end of the exhaust tube includes one or more holes permitting exhaust gas to flow around the end of the exhaust tube between an outer wall of the exhaust tube and the inner shell of the coolant passage to regulate a temperature of the inner shell of the coolant passage.
    Type: Grant

  • Apparatus and method for the characterization of respirable aerosols
    Patent number: 9354218
    Abstract: An apparatus for the characterization of respirable aerosols, including: a burn chamber configured to selectively contain a sample that is selectively heated to generate an aerosol; a heating assembly disposed within the burn chamber adjacent to the sample; and a sampling segment coupled to the burn chamber and configured to collect the aerosol such that it may be analyzed. The apparatus also includes an optional sight window disposed in a wall of the burn chamber such that the sample may be viewed during heating. Optionally, the sample includes one of a Lanthanide, an Actinide, and a Transition metal.
