Magnetic blow-out arc extinguishing device In prior-art cicuit breakers or contactors, the rapid extinction of the arc drawn between the separated contacts is enhanced by suitable magnetic blow-out means, and it is known to shunt the blow-out coil by auxiliary contacts in the closed circuit position of the circuit breaker, or to energize the coil only at the appearance of an arc by arc transferring means including a connection electrode.

- When the cause of death is potentially related to drugs or toxins the time it takes to certify a toxicology report is related to how complicated the case is and how many drugs are detected by the initial screening assays. For relatively uncomplicated cases the results are usually certified in 14-21 days.

And since the dead won't be revealing their secrets anytime soon, it's up to scientists to explain what happens when a person dies. Death, just like life, is a process, scientists say.The first stage of this process is known as clinical death. It lasts from four to six minutes, beginning when a person stops breathing and the heart stops pumping blood. During this time, there may be enough oxygen in the brain that no permanent brain damage occurs.eath, just like life, is a process, scientists say.

Overview When there is no measurable activity in the brain and the brainstem, this is called brain death. In a person who has been declared brain dead, removal of breathing devices will result in cessation of breathing and eventual heart failure. Brain death is considered irreversible.
