  • Patent number: 6715581
    Abstract: A chromed exhaust pipe and muffler for motorcycles that is capable of withstanding the extreme heat generated at high rpm's of a motorcycle engine without discoloring or “bluing”. A double wall construction is utilized for the exhaust pipe and muffler with the back side of the exterior chromed pipe cut away along the length of the pipe from the mounting flange to the muffler core. The cut-away exterior pipe is dimensional to allow the interior pipe to be inserted in one piece from the mounting flange to the muffler core, as well as cooling the exterior pipe, thereby preventing heat discoloration of the exterior chromed pipe. Spacers are welded to the interior pipe and the exterior pipe at the backside cut-away of the exterior pipe to space the interior pipe within the exterior pipe. The muffler core includes a baffle core enclosed by an interior pipe section, allowing gases to flow out the back end only. The interior pipe is spaced apart from and enclosed in the exterior chromed pipe.

  • Patent number: 6648099

A double wall construction is utilized for the exhaust pipe and muffler with the back side of the exterior chromed pipe cut away along the length of the pipe from the mounting flange to the muffler core. The cut-away exterior pipe is dimensional to allow the interior pipe to be inserted—one piece from the mounting flange to the muffler core, as well as cooling the exterior pipe, thereby preventing heat discoloration of the exterior chromed pipe. The muffler core is completely enclosed by an interior pipe section, allowing gases to flow out the back end only. The interior pipe is spaced apart from and enclosed in an exterior chromed pipe. The double walled muffler section prevents discoloration and reduces heat transfer to the exterior chromed pipe.

  • Patent number: 4870343
    Abstract: A high voltage detecting device has an input terminal for receiving electrical energy and includes a first circuit having a gas filled tube receiving electrical energy from the terminal. The gas filled tube provides a visual indication of the presence of high voltage. A second circuit also receives electrical energy from the terminal and is coupled in parallel with the first circuit. The second circuit provides an audible and visual indication of the presence of high voltage. The high voltage detecting device is contained in a test stick having a housing. The housing includes three compartments for holding the first and second circuits along with a power supply for the second circuit. The two independent circuits in the test stick provide a positive indication of the presence of high voltage over a broad range of transmission and distribution applications.
