Abstract: An electric power generating system including a motor vehicle defining a passenger compartment and an engine compartment; an internal combustion engine retained in the engine; an exhaust system defining a passage for discharging exhaust gases produced by the internal combustion engine; and a primary heat exchange system coupled to the exhaust system means and defining a primary chamber adapted to transfer thermal energy from the exhaust gases to a working fluid; a cooling system for circulating cooling liquid in a path that results in removal of thermal energy from the internal combustion engine; and an auxiliary heat exchange system coupled to the cooling system and defining an auxiliary chamber adapted to transfer thermal energy from the cooling fluid to the working fluid.

Abstract: A self-lighted safety helmet, comprising a helmet body with a phosphorescent outer shell member; and a radiation source providing radiation to the outer shell capable of inducing phosphorescence of the outer shell, to project luminescence from the helmet to increase helmet visibility.

Abstract: A fire sprinkler including a body defining an inlet adapted for connection to a supply of fire extinguishing fluid and an outlet adapted for placement in a zone to be sprinkled; a valve retained by the body and movable between a closed position providing a fluid tight seal between the inlet and the outlet and an open position allowing fluid flow therebetween; an actuator for moving the valve from the closed position to the open position in response to a predetermined condition; and a deflector disposed to disperse into the zone fluid discharged from the outlet; the deflector comprising a plurality of deflector elements each adapted to deflect fluid discharged from the outlet. Also included is a coupling between the deflector elements and adapted to permit adjustment in the relative positions of the deflector elements so as to selectively change the pattern in which fluid discharged from the outlet is dispersed into the zone.
