Abstract: A cooking unit may operate using multiple types of fuel to cook food. One or more first heat source, such as gas burners, electrical resistive heaters, and/or other heating technology, may provide radiant heat to a cooking chamber. One or more second heat source, such as a firebox, may provide indirect heat to the cooking chamber, for example by producing smoke. User operable controls and/or an automated control unit may alter the rate at which a fuel and/or air is supplied to one or more heat source.

Abstract: A mechanical breather system for a four-stroke engine includes a rotating member. The rotating member can have at least one inlet channel in fluid communication between an outer perimeter of the rotating member and an inner region of the rotating member. A breather housing having an air receiving chamber formed therein is fluidly coupled to the at least one inlet channel of the rotating member. A passage can be formed through a wall of the breather housing is in fluid communication with the air receiving chamber and an exterior of the breather housing.

Abstract: A powered blower/vacuum unit includes a base portion having a housing and a power air-moving device within the base portion. A tube is provided that is formed by a first manufacturing operation, such as a blow molding process. The tube extends a relatively large distance away from the housing and air flows through the tube along a relatively large distance. A coupler is also included for coupling the tube to the housing. The coupler is separately formed by a second, different manufacturing operation, such as an injection molding process. The coupler includes a plurality of one-way snap-in features configured to engage a plurality of receiver features located on the tube to non-removably attach the coupler to the tube. The housing can also include at least one male component and the coupler can include at least one complementary female component for securing the coupler to the housing.
