Abstract: A pivoting seat belt system includes a seat belt retractor and a seat belt receiver, each of which are pivotably mounted to a head of a bracket that is pivotably mounted to a ROPS located behind an operator seat of a zero turn mower. The head of each bracket restricts the angle of pivoting of the seat belt retractor and seat belt receiver, and a slot in each bracket restricts the angle of pivoting on the ROPS.

Abstract: An article and drink sheltering assembly includes a frame including a plurality of supports and a base. Each of the supports is attached to the base. The supports are pivotally coupled to the base and are positionable in a deployed condition extending upwardly from the base or in a collapsed condition lying on the base. The frame has a height, length and width each being less than 20.0 inches when the frame is in the deployed condition. The supports at least include a first support and a second support. The first support defines a front support and forms an opening into the beverage shelter assembly when the first support is in the deployed condition. A cover of flexible material is attached to the frame. The cover extends over and is attached to each of the supports to define a canopy when the frame is in the deployed condition.

Abstract: Power plant systems and processes are described that enable recovery of at least a portion of the fuel storage energy associated with a storage system for supplying fuel to the power plant systems. A first embodiment of an energy-recovery power plant system includes at least one fuel storage container and at least one expander that can receive fuel from the fuel storage container at a first pressure and provide the fuel to the power plant at a second pressure that is lower than the first pressure. A second embodiment of an energy-recovery power plant system includes a first conduit fluidly coupling the fuel storage container and the power plant for delivering fuel from the fuel storage container to the power plant and at least one regenerative thermodynamic cycle engine thermally coupled to the first conduit such that heat may be exchanged between the fuel and a working fluid for the regenerative thermodynamic cycle engine.

Abstract: A method for operating a cooling subsystem of an electrochemical fuel cell system during startup is disclosed. The method comprises directing a startup coolant through an electrochemical fuel cell stack of the fuel cell system, and directing a standard coolant through the fuel cell stack when the temperature of either the fuel cell stack or the startup coolant reaches a first predetermined temperature, wherein the heat capacity of the startup coolant is different from than the heat capacity of the standard coolant. Cooling subsystems are also disclosed.

Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump—dual loop cooling subsystem. During startup, one pump directs coolant through a startup coolant loop and after either the fuel cell stack or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop is then directed to the fuel cell stack. In an embodiment, coolant from the standard loop mixes with coolant in the startup loop after the predetermined threshold temperature is reached.
