Abstract: A wire winding gun head for winding conductive wiring to form electrical coils. The wire winding gun head having a body, a movable element and a needle. The body has a longitudinal axis. The movable element is coupled to the body, and the movable element has a profile therein. The needle is carried by the body, and the needle is extendable/retractable dependent upon the profile and a position of the movable element. The needle is configured to receive wire and to supply the wire out of an end of the needle.

Abstract: An exhaust gas-cooling device for use on an exhaust gas conveyance system of a vehicle having an exhaust gas passageway to emit exhaust gases from an engine to an outlet includes an exhaust passageway pipe in fluid communication with the engine, and a micro-venturi mixing chamber pipe in fluid communication with and located downstream of the exhaust passageway pipe. The micro-venturi mixing chamber pipe defines the outlet of the exhaust gas-cooling device and has at least one aperture disposed on a pipe body of the micro-venturi mixing chamber for introducing ambient air into the micro-venturi mixing chamber pipe.

Abstract: An exhaust gas-cooling device for use on an exhaust gas conveyance system of a vehicle to emit exhaust gases from an engine to an outlet includes a pipe defining an exhaust gas passageway that is in fluid communication with the engine, and a diffuser in fluid communication with the exhaust gas passageway. The diffuser is configured for receiving the pipe, and has a body defining an outlet of the exhaust gas passageway to the ambient, and a diffusing structure disposed on the body generally opposite the outlet. The diffusing structure has a separating structure configured for receiving and diverting the flow of exhaust gas emitted from the pipe, and a guiding structure configured for guiding the diverted flow of exhaust gas along the body to the outlet.
