A two stage reaction for the production of steel from iron carbide is carried out in two separate but interrelated reactors. In the first reactor, iron, carbide, with slag formers, is fed into a feed end and the reaction is well-mixed by the vessel geometry, the stirring action below-surface injection of oxygen and iron carbide feed, and the evolution of gases from the liquid metal bath. The produ...

An engine (1) and generator/motor (26) are connected to the input shaft of a continuously variable transmission (30), and the output shaft (37) of the continuously variable transmission is connected to drive wheels. A target value of a coasting torque acting on the output shaft during coasting is set according to a vehicle speed. A real coasting torque is estimated from the output torque of the en...

An antilock brake system which decreases a braking pressure to prevent drive wheels from locking is applied to a hybrid vehicle wherein an engine and a motor are connected to the drive wheels via a continuously variable transmission. The rotation torque of a motor is applied to the drive wheels when the braking pressure is reduced due to antilock control so that the engine braking force which acts...

The fire alarm method involves transmission of ultrasound signals from one transmitter and microwave- or optical- signals, or a combination of all three different wave-types from an additional transmitter. Doppler signals reflected from objects are received by receivers assigned to the transmitters, and the received signals are evaluated separately and in combination, so that a varied reception si...
