Abstract: A leak-free flexible conduit and method of making the same is described. By attaching a flexible outer hose to a flexible inner hose without directly clamping the outer hose to the inner hose, the life of the inner hose is increased. Furthermore, the outer flexible hose creates a heat-resistant, airtight seal that prevents exhaust leaks from the inner flexible hose from escaping, substantially reduces the heat lost to the atmosphere, decreases the amount of vibration, reduces noise, and protects the inner flexible hose from corrosive elements and contaminants, thereby also extending the life of the inner flexible hose.

Abstract: An illuminated button for use with a shuttle knob mechanism. The mechanism includes an actuator disposed through a resilient member that is captured by a first retainer and supported by a second retainer and a light guide. The light guide is disposed through the light pipe and functions to illuminate on the face of the button.
