  • Patent number: 5801344
    Abstract: A double throat tuner including a second conduit concentric to a first conduit which connects the gas flow to a first volume tuning chamber having a first effective volume. The radial difference between the first and second conduits and the length of overlap of the first and second conduits in combination with the effective volume of the first tuning chamber attenuates a preselective frequency of sound. This attenuation is for a specific frequency range in addition to the overall attenuation of the complete system including a plurality of conduits serially connected by a respective chamber.

  • Patent number: 5336856
    Abstract: An active noise cancellation system is used to quiet engine exhaust noise. Combustion product from an engine passes through a conduit to an acoustical mixing chamber located in the tailpipe. A microphone senses noise in the vicinity of the tailpipe and provides a signal to a control unit. The control unit generates a controlling signal sent to one or more speakers mounted in a housing that is coupled to the tailpipe. Sound produced by the speakers enters the mixing chamber to mix with and cancel sound from the combustion product exiting he conduit. Some embodiments include a muffler housing forming an interior chamber which is divided into two sub-chambers. Other embodiments include a muffler having an outer housing enclosing an inner housing. Variations have been devised regarding the number of speakers mounted in each chamber and the way in which they are mounted.

  • Patent number: 5245409
    Abstract: The invention provides a method and apparatus for on-line, real-time imaging and inspecting a seam weld on a moving tube in a conventional tube forming environment. The apparatus is in a compact container sealed from workplace contaminants. A planar light source directs a steady plane of light by using mirrors, through an aperture in the container and onto the tube seam at a 45.degree. angle relative to the tube axis, forming a light pattern on the moving tube. A camera in the container images the light, again at 45.degree. relative to the tube axis, and said image is displayed remotely on a conventional video monitor. An operator interprets the light pattern image and adjusts the tube forming apparatus accordingly.
