Abstract: This is a multi part clip installed under the seam of a raised seam roof that allows secure attachment of objects to the roof. One component of the invention is a base clip constructed from thin gage sheet metal and having multiple holes with some dimpled for fasteners. Another component of the invention is a vertical clip also constructed from thin gage sheet metal and having slots on either side to allow fasteners for attachment through the vertical clip. The two components when installed under a new or a pre-existing raised seam roof allows secure permanent or temporary attachment of objects using clamping force applied over the reinforcement clip without the need for deforming or changing the visual esthetics of the roof panels. This produces more support for vertical, lateral, and downward pressure.

Abstract: A pair of rake wheels in an assembly is referred to as a center splitter assembly. Each rake wheel is configured for free-rotation, meaning it is powered by contacting the ground. The center splitter is used to separate material, each wheel moving material in a different direction. The rake wheel on the left side of the center splitter assembly will rotate in a clockwise direction, as viewed from behind the wheel, which will cause the material to move from the right to the left. The opposite applies to the rake wheel on the right side of the center splitter assembly, where it will rotate counter-clockwise, moving material from the left to the right. Since these rake wheels are attempting to move material in opposite directions, the spacing between the wheels has been found to be critical.

Abstract: The process of active DPF regeneration requires that the DPF be brought to regeneration temperatures in excess of 550° C. to 600° C. for a period of time sufficient to accomplish soot burnoff in the DPF. Similarly, during cold start up it is desirable to bring the catalyst to light off temperature as soon as possible. The large thermal inertia of one or more turbochargers delays the exhaust gas at the DPF from reaching critical temperature quickly. The incorporation of a low thermal inertia, insulated, turbocharger bypass duct avoids thermal energy loss from exhaust gas to the turbine housing and shortens the time for the DPF to reach critical temperature for active DPF regeneration, or in the case of a catalytic converter, shortens time for catalyst to reach light off temperature.
