Abstract: According to the invention, a steam generator is provided with a housing for forming a steam generating chamber, the housing having a steam outlet port. A heater plate is supported by the housing within the steam generating chamber. A water inlet valve is fluidly connected to the housing for selectively supplying water into the steam generating chamber whereby water is directed to the heater plate for conversion to steam. The heater plate forms a bottom wall of the steam generating chamber and is arranged to have a high point. The water inlet valve is opened and closed in accord with a duty cycle which alternates between two phases: a fill phase duty cycle and a steady state duty cycle.

Abstract: A transom window assembly is provided that comprises a windowpane and an openable transom pane, the windowpane and the transom pane being adjacent to each other. A transom hinge hingedly connecting the windowpane and the transom pane to each other comprises a first hinge portion attached to the interior surface of the transom pane along a lower edge, preferably directly attached, and a second hinge portion attached to the interior surface of the windowpane along the transom opening edge. The transom window is capable of being swung between a closed position and an open position. Certain embodiments of the window assemblies have a flush appearance. Also provided are vehicles comprising a vehicle window assembly in accordance with those just described.

Abstract: The auxiliary power unit includes an auxiliary liquid-cooled diesel internal combustion engine for driving power producing equipment on board the vehicle. A first conduit connects the main engine liquid coolant outlet in fluid communication with the auxiliary engine liquid inlet. A second conduit connects the main vehicle engine liquid inlet in fluid communication with the auxiliary engine outlet. A pump recirculates the liquid coolant through the conduits so that the auxiliary diesel engine heats the coolant and thus the main engine, when it is not in use. The engine is controlled remotely from the vehicle cab.
