was generated the quality of pressure of the current throughout the whole lighting area, with
devices for indicating what such pressure might

"Sixth-To design efficient dynamos, such not
being in existence at the time, that would convert
economically the steam power of high-speed engines into electrical energy, together with means
for connecting and disconnecting them with the
exterior consumption circuits; means for regulating, equalizing their loads, and adjusting the
number of dynamos to be used according to the
fluctuating demands on the central station. Also
the arrangement of complete stations with steam
and electric apparatus and auxiliary devices for
insuring their efficient and continuous operation.
"Seventh-To invent safety devices that
would prevent the current from becoming excessive upon any conductors, causing fire or other
injury; also to invent switches for turning the current on and off; lampholders, fixtures (sockets),
and the like; also means and methods for estabfishing the interior circuits that were to carry
current to chandeliers and fixtures in buildings.
