Michael Mosley, Cassie Newland and Mark Miodownik from the BBC series 'The Genius of Invention' describe the scientific achievements of Nicklaus Otto, Karl Benz and Henry Ford. Prior to this, the steam locomotive had started a revolution. Richard Trevithickâs design had a boiler but this was removed to make the internal combustion engine. The German inventor Nicklaus Otto developed the first four-stroke engine in 1876. This could not be developed until kerosene, diesel and petrol were used in place of coal. Karl Benz then developed the worldâs first car using Ottoâs design.
A welding arc stabilizer including a source of high voltage and a switch for switching the source of high voltage across the electrode and the workpiece in the event the arc rectifies. The high voltage is switched across the electrodes within the completion of the half cycle in which rectification occurred.

Arc chutes are an integral part of a modern industrial or power circuit breaker. As the circuit breaker contacts open, the arc chute segments, cools, and moves the arc away from the contacts. Moving the arc away preserves the integrity of the contacts for a longer service life. Standard arc chute designs absorb about 80% of the energy released during an interruption. These drawings show a typical arc chute in cross-section: NEW ARC CHUTE TECHNOLOGY The new MASTERPACTÂ® NT and NW power circuit breakers, the P- and R-frame molded case circuit breakers, and COMPACTÂ® NS 630bâ3200A circuit breakers have a unique patented arc chute assembly. In addition to the standard arc chute plates, the arc chutes include a series of metallic
