Lykes Bros. Buy Shius

Lykes Bros, of New Orleans, have
purchased the Lake Slavi, an oil-hurn-

from the Shipping Board, it was
learned yesterday. She will be oper-
ated from the Gulf to West Indian
ports. While the price was not re-

$4,000, which is u.s. ally asked by the
board for its lake type steamers.
Lykes Bros. are said to be negotiating
for the purchase of three more vessels.

Lesson No. 35
THE THERMIONIC TUBE-PART
2-THE PLATE

THE GLA i
Part ! of this series on the tner-
mionic tube showed the function OF
the filament to be that of an electrong
generator In order that the effect OF
the plate and later the grid may De
simply explained, it becomes necessary
to give in brief the acton OF electric
charges when free and also when IN
der the influence Of other electric
charges.
There are two kinds of electric
charges: one positive. the other mega
five. II has been said that all matter
is believed to be composed OF these
electric charges. In order that mat
ter under this theory will be stable,
the structure of the atom is that oil
positiye-charged electron, surrounded
nv a number of smaller charged ne
gative electrons, the quantity OF these
negative electrons being sufficient to
keen the system neutral or stable
n will be mentioned here that cleo
trio charges. like magnetic poles, obey
somewhat the same laws; namely, un-
like charges attract and like charges
repel
If now we consider the thermionic
tube containing a filament and plate
in a vacuum we can study the eff
fects produced under certain cond'-
tons of operation. If we first grad
nallv heat the flament, we SLOWLY
disturb the structural state of rest
until a point is reached where the fila
nent throws off negatively charP' i
electrons. Increasing the heat OF the
filament increases the number Of cleo
irons thrown off. However, when
negatively charged electrons leave the
flament, state Of electrical equlll-
brium no longer exists; the tilament
assumes a positive charge due to the
departure Of the rputralizing mega
tive electrons. Unlike charges at
tract, therefore, the flament draws
the negative electrOns back to it and
thus We can mentally picture the
flament in much the same role as n
fountain from which water Is forced
perpendicularly only to fall back by
gravity.
If a positive charge with respect to
the filament be placed on the plate in
the thermionic tube, it will attract the
negatively charged electrons to the
plate. This flow Of electrOns to the
plate constitutes the passage of an
electric current. the direction of the
current being from the plate to the
tilament.
If a negative charge with respect
to the filament be placed on the plate,
it will repel the negatively charged
electrons towards the filament pre-
venting them from reaching the plate
in consequence of which there will be
no current flow
Alexandria gazette. [volume] (Alexandria, D.C.) 1834-1974, 1922-05-18

Bv studying figures = and 3 ii can
be seen that because of the closcness
Of the grid TO the filament, small
negatively charged and no plate cur
rent because the electrons are pre-
vented from reaching the plate by
the negative charge on the grid. Fig
ure 3 shows a positive charge on the
rid allowing the electrons to reach the
plate, and a consequent flew OF cur
rent in the plate circuit.
For sake Of illustration the poten-
tial on the grid is indicated as being
furnished by a battery rather than
the usual receiving inductance.
The energy in the plate circuit de
ponds on the amount of iilament ennis
sion and the voltage or potential OF
the plate. The control oil the grid
over this energy depends on It's close
ness to the filament, its charge, and
its construction. By reason of the
small amounts fenergy on the grid
which can be made to control greater
amounts of energy in the plate cir
cult the thermionic tube possesses
simplifying properties which are Of
great Importance in radio telegraphy
and telephony
