1'0 YEARS AGO
I Among the items of interest to
Norwalk tea 3'mrs ago are the fol-
of
lowing. which are taken from The
Sentinel of May ‘.‘.'th. 1914:
"Louis R. Hendricks. one of thc
linemen cmployml by the Southern
New England Telephone Company.
was seriousiy injured yesterday at-
ternoon. when he received a, shock
and fell a considrrable distance from
One of the company's poles?“
"The Noru'alk Country Club has
recently crvmplr'fcrl two up-to-date
roque courts which will be played
upon for the first tlm‘? Memorial
Day. Iloque is Americanized and
scientific crfiquct.”
"‘Charlcs Younz‘s new boat 'Go-
‘Some' is tiFd up in the East Nor~
walk Yacht Club float. If the boat
lives up to its name an enjoyable
season Will rostiit.”
"Mr. and Mrs. Frank J. Finnegan
at South Main s-reet spent yester-
du' in New YOri-t.”
' “In 3'ic33' of the fact that the City
Clerk's office will be closed tomor-
raw, the checks for the firemen and
the street. department were issued
today.”
"The executive committee of the
Boy Scouts held a meeting at the
oQice of the president Ira. 0. Greg-
015-, last night and decided to hold
a. two weeks’ camp in “’eston. com-
mencing as soon after the Fourth
of. July as possih‘e. A committee
consisting. of Judge John Keogh.

apart. The secondary is wound be-
tween two discs 3-16 of an inch
apart. and contains about 750 turns.
If desired. the secondaries may be
tuned with .0005 mid. variable con—
densers, but this is not necessary.
It might be mentioned here that
in most transformer-couplcd inter-
mediate amplifiers, it is estimated
'hat the first stage is uscd to make
up {or losses occuring in the. first
detector in the process of changing‘
frequency. so that a real gain in re-
sul—ts does not begin until the acc-
0nd step.
One of the best forms of inter-
mediate amplifier is that illustrated
at the top of the column. and is
simply a. neutrodyno with coils de-
signed for lonngavc work instead
of short Wave. It is advisable to use
‘clthct‘ a.triple hank-wound coil or
some efficient form of multidaycr
coil for this work rather than the
hohbin~type used in the transform~
nrs previously described. Coll "B"
in each case consists of about 400
turn: of .\'o. 1‘6 or 25 double-cotton-
co3'ered wire. tapped at about the
Rnth turn from the "positive" “B"
battery end of the coil for the neu-
trodyne condcnscr conncctlon. Coil
“A" is of thersame sizeI wire, and
should be about 100 turns.
Condenser "C" is preferably a 1633--
‘mss condenser of either .00025 or
.0005 mtd. capacity. 'l‘hrI neutraliz-
ing capacity "C-l" may be a midgct
vernier condenser.

Current Carried
Only One Way

By CARLTON E. BITTLER,
(“.3le Engineer.)
The two element Vacuum tube
one containing a filament and a plate
such as the Fleming valve. has a
constant flow of electrons from the
:ilamcnt is heated to incadOSCancc
03' means of an electric current small
particles called e lectrons 113' off and
are attaracted to the metal strip that
is called the plate.
The llow is constant and in only
' one direction; that. of from the Illa.-
ment to the plate. Alternating cur-
rent. radio signals in attempting to
cross from the filament to tile plate
will be electrified. Only the halt
cycles that are in the direction of
the lectronic tlow will be permitted
to cross. The other half of the cycle
cannot cross from the plate to the
filament due to the stream of elec-
trons barring its passage.
In this manner the two clement
vacuum tube acts simply as a. de-
tector and rectifier of the radio cur—
rents. For reflex circuits and other
hookups that require a rectifier such
as a. crystal, the'two clement tube
’fuuctiohs excellently. ,
1n the three element tube. com-
monly used in radio work, a mesh
or fine wire is placed between the
lilarnent. and the plate. This is call-
ed the grid. The addition is this ele-
ment. to the two element tube makes
possible its use not. only as a. detectr
or and rectifier of current, but. also
a. generator of high frequency cur-
rents and as an amplifier.
