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.
As new standards continue to raise the awareness of arc flash hazards, users are looking for leading-edge products capable of delivering these higher levels of safety. To meet these needs, Rockwell Automation developed the Allen-Bradley CENTERLINEÂ® 2100 motor control center (MCC) ArcShieldâ¢ . This version of the CENTERLINE 2100 MCC provides unmatched arc flash protection in a low-voltage MCC (up to 600 volts). Rockwell Automation is the first equipment manufacturer to apply arc-containment features to features to low voltage NEMA MCCs.
