CONTESTS ARE ARRANGED

Prizes for Best Receiv-

All roads led to Brooklyn yesterday
for radio fans Of New York city, and
apparently, of nearby States. Their
destination was the Brooklyn Ice Pal
ace, Bedford and Atlantic avenues,
where the Electrical Contractors AS
sociation of Brooklyn and Queens
opened it's first annual radio and cleo
trical exhibition.
Although radio equipment has been
as rare as silence in the ether, the con-
tractors have gathered together under
one roof more than a million dollars
worth Of wireless apparatus. More
over equipment was for sale as well
as for demonstration purposes. APP
parently the big manufacturers are
beginning to catch up on the demand
that overpowered their big plants dur
ing the winter months. The dealers
believe they will be able to supply all
calls during the two weeks of the
show.
T.-l Ice Palace has been transformed
into beautiful garden, and there is
no sign of frost such as might be ex-
pected from its name. A canopy of
golden brown covers the roof, and
green pergolas. arranged in four long
rows, are the booths in which the ma
terial is displayed.
Everything i'm Radio Line.
Everything in the way of radio equip
ment can be seen, from the precious
vacuum tubes to the lowly crystal de-
tcctors. There are A batteries, B batter
les. dctectors, amplfiers, transmitters,
antenna WIRE sockets, loud speakers, in
sulators. lightning switches. head phones,
handsome cabinet sets inexpensive
single circuit sets, rheostats, vario
meters transformers. tickler coils. volt
couplers loose couplers, variometers,
transformers. ticker coils, volunteers
condensers and text books. The only
thing that was missing was an Alex
anderson alternator, which requires
eight freight cars for shipment and
therefore was left out by mutual con-
sent.
The equipment. however. was not the
only bid for the attention of the visitors.
VA addition. various contests VIII con-
tlnue until the end of the show, and ex-
hbits OF interest for those who are
thinking of installing sets. One Is
r,odol of house equipped with radio
apparatus installed in conformance with
Tho regulations of the New York Board
or Fire Underwriters. The model visual
izes for puzzled enthusiasts who are
worried about their fire insurance the
correct precautions to be taken against
lightning and other fire hazards.
This model house is in the booth OF
the Copper Clad Stel Company. The an
tenna and wiring was installed under
the direction of j. c. Forsyth, chief in
spcctor Of the New York Board of Fire
Underwriters. Representatives of the
board explain the installation and in
struct radio owners concerning the new
rules of the board.
Must BE lightning Arrester.
The experts told hundreds yesterday
that the most important changes in the
rules are those requiring the installation
Of a lightning arrester and prohibiting
the use of gas pipes as ground connec-
ton for this safety device. Preference
for the ground connection Is given to
water pipes. but the steel frames of
buildings. pipes driven into the ground,
plates buried in the ground, &C., are per-
mtted
The rules provide also that aerial
wires outside the house shall not cross
over or under power or lighting circuits
OF 600 volts or more; that lead In wires
shall not be smaller than No. IA copper
or No. IL approved copper clad; that
not obviate the necessity of lightning
arresters. and that inside wires shall
not come closer to electric light or
power wires than two inches unless sep
arated by continuous" non-conductor.
One contest that is arousing keen in
terest in all that attended yesterday. but
particularly among the boys. was the
radio receiving set competition for Boy
Scouts The radio scouts are competing
for two prizes, one for the smallest and
hest receiving set and the other for the
hest receiving set, regardless OF size. In
addition to cash prizes, knock down"
miniature engine has been offered by
the III. e. Boucher Manufacturing Com
pany.
Another contest open to all is for the
Crocker- Wheeler motor generator This
will be awarded to the entrant who
shows the best set that may be con-
ceaIcd upon an individual and that will
permit him to communicate over rea-
sonable distance with another person.
The competition was designed to bring
forth real results In the pocket set field
in the belief that such a set will be OF
real utility to police departments and In
other fields soon. So far pocket sets
have been merely toys but 1t is hoped
to develop them into powerful factors
in modern communication. Tests OF
the various sets submitted will be made
during the show.
Although Stephen T. Rogers, n1anag-
ing director. and his associates have put
much material into the show the part
most interesting TO many visitors will
come in of its own accord during the
show This part will be radio concerts,
vocal and instrumental. addresses on
dozens of topics, advice on radio mat
tcrs and divers other features which
will come from the air by way of the
big antenna on the roof from all the big
broadcasting stations In this section OF
the country. Loud speakers will make
audible the winged words and ethereal
music OF WIZ. WGY, WBZ, wGI
KDKA. WvP and the others. till be-
wildered novices In the rat-o field Will
get The idea that all the world has
come to Brooklyn.
