Abstract: A method of operating an electric current producing power cell comprising precharging the power cell; applying a current to heat a bi-metal heating element; applying voltages so as to cause a first cell to assume exhaust gas motion; irradiating gases in an alternate cell to force gas movement in a direction, away from a negatively charged collecting plate; producing a high internal gas temperature through molecule collisions to cause gas expansion; conducting the gas mix at high speed through a plasma discharge channel in a direction perpendicular to an impressed magnetic field; and drawing an electric current produced thereby; reversing electrical charges and repeating the process continuously in each of the alternate cells.

Abstract: A laser multiplexing system is capable of time-sharing high-power laser output among a number of work stations. The laser beam is directable in quick succession into the ends of various optic fibers leading to remote work stations. The precise position of focus of the beam into each fiber is originally determined and continually monitored during the beam travel cycle for each work station.
