Abstract: A method for controlling a car with a parallel hybrid system comprising at least a combustion engine and an electrical machine in P0- or P1-configuration, with a clutch for connecting the combustion engine's output shaft with at least one drive shaft. Steps include determining a power demand Pd, and decoupling the combustion engine from the drive shaft if the power demand Pd is below a first threshold P1. Coupling the combustion engine with the drive shaft when the power demand Pd is above the first threshold P1 provides additional fuel savings when the method further comprises shutting off the combustion engine and providing power to the drive shaft by providing electrical power to the electrical machine to drive the car, when the power demand Pd is between the first threshold P1 and a second threshold P2. The second threshold P2 is greater than the first threshold P1, i.e. if P1<Pd<P2.

Abstract: A drill stem guide and cover system is designed to guide a drill stem used in coke cutting operations. After a cutting tool and drill stem are inserted into a coke drum, covers close, forming a passageway small enough that it prevents the cutting tool on the end of the drill stem from being removed but large enough to allow movement of the drill stem. The drill stem moves within the passageway to allow the cutting tool to be raised and lowered as needed. The closed covers provide protection from the release of pressurized or explosive gases while the coke cutting operation is taking place. The covers can be automated so that an operator can control them from a safe distance, and the covers can be remotely opened for the removal of the drill stem and cutting tool when coke cutting operations are not taking place.
