Abstract: Systems, methods, and apparatuses for implementing “Band Karaoke” as a platform to make music creation, either alone or in groups, more accessible to novice level participants, are described herein. More particularly, there is described, a specially configured system for systematically generating skill adapted musical arrangements on a per-user basis of a common musical piece for the collective performance by the users as an ad-hoc band. Other related embodiments are disclosed.

Abstract: A down flow, two tank, two pass radiator includes a flow division baffle in the center of the upper tank that automatically vents any air trapped behind the baffle as the engine operates. When the engine starts, colder coolant has contracted a thermo wax operated baffle slide to an open position, allowing any trapped air to vent through. As the engine and coolant warm to normal operating temperature, the wax expands, pushes the slide closed, and the baffle operates as a solid piece.

Abstract: A down flow, two pass radiator includes a means for selectively venting air displaced during coolant fill from one side of the top tank flow baffle to the other, while the baffle remains fluid tight during normal operation. The uppermost wall of the top tank slopes continually upwardly from the far, low end of the tank to a filler neck at the opposite, high end. A vent inlet through the baffle, near the inner surface of the uppermost wall, may be covered and uncovered by a blocking valve accessible from outside the top tank. The valve is left closed during normal radiator operation, but opened during coolant fill to allow free escape of displaced air across the baffle and out through the open filler neck.
