Photo—Electricilell Used
To Check Labels, Feel,
Smell, and Count

Flashing lights, clicking relays,
and glowing tubes amorded a World’s
Fair atmosphere to the Electronics
show, now going on at the Chicago
Lighting Institute, located on the
thirty—sixth floor of the Chicago
Chicago Civic Opera building. This
interesting exhibition will continue
for the rest of the week, and will be
open from ten until nine o’clock. A
lecture and demonstration will take
place at eight P. M. The A. S. M. E.
will assist in the demonstration.

At the lecture last Friday evening-
Mr. A. J. Germain, electronics ex—

 

pert of Westinghouse Electric com-
pany, gave a talk on the commercial
applications of electronics. A simplei
explanation of the action of the
photoelectric cell was presented
prior to the demonstration.

Better Than Human

Many processes depending on hu-
man care are now done more accur.
ately by use» of the photo-electric cell.
Matching medicines, checking labels,
sorting boxes, wrapping packages
and other like processes are now be
ing done by the untiring photo—elec-
tric tube.

Just as the photronic tube is called
the electric eye, the grid—glow tuibe‘
may be called the electric teeler. This
tube is so sensitive that it can detect
the presence of a human body threei
feet away. Merely breathing on a
plate connected to'the tube can con-
trols unlimited power. The tube is
now extensively used lor a burglar
alarm.

The second part of the dcmonstra- 1
tion was on the subject of illumina- l
tion and included a display of the
most modern lighting equipment
available. Mr. C .W. Zersen, assist-
ant manager of the Chicago Lighting
Institute, was the speaker. After
giving a short explanation of the
psychological effect of colored light-
ing, he gave a demonstration bearing
out his point.

 

 

 

Use Sodium Vapor Laimps
It was then demonstrated that,

 

decoration by colored lights was one
of the most effective means. A
sodium vapor lamp giving three,

times as much light as a mazda lamp 1
of the same wattage. was then]
shown. Because of its brilliant yellow
hue, the light is restricted in its uses.
The light is being used at present
for economical highway illumination.
A mercury vapor lamp of similar ct,
ficicncy, but also hampered by its
blue green color. was then shown.
This light gave a brilliant white
beam.

Ultra-violet demonstrations were
then given, under which glass eyes
sparkled, teeth shone, painted finger-
nails glowed, and false teeth gave
elf a delicate pink hue.

 

Senior Fire Protects
See Furniture Plant

The Storldine Furniture Corpora-
tion of 4400 W. 26th Street, a large
manufacturer of baby furniture, was
inspected by the senior Fire Protect
class a week ago last Friday after—
noon.

The inspection trip, which is one
of a series conducted during the
semester, was the most interesting
of those taken thus far. The of-
ficials, who conducted the group
through the factory, planned this
trip in such a manner, that the en-
tire factory was inspected in a sys—
tematic fashion.

hearers, Negotiating
For Tennis Grounds
Profesoor Hannsvfiischer, sponsor
of the Fencing Club, is making ar-
nangcments for the use of the tennis
courts as a practice grounds. for the

 

 

 

 

fencing team.

The popularity of this sport is ris~
mg as is seen from the fact that six
new students and two faculty mem—
bers have joined the club. Instruc-
tions in the use of the epee and the
light saber are given; in addition,
the use of the broadsword will be
taught as soon as the equipment is
purchased.

Fresh air is air which is not con—
taminated with carbon dioxide, sewer
gas, cuss words, gossip, or tobacco
smoke. It consists of the highest
quality of oxygen and nitrogen with
a little ozone thrown in to give it tone
and is the very finest article used for
breathing purposes.

Out in the mountains, far from the
haunts of man, the air is fresher than
country butter. After a man has
breathed in a few million cubic feet
of it he can eat an ex, hoofs and all,
and thinks nothing of taking a small
sized bear across his knees and spank-
ing him severely. But the air in a
large city is of a much inferior qualv
ity. It has been used so much and
has been mixed with so many kinds
of odors and gases and has had to
mingle with so many sex plays in the
theaters and so much politics outside,
that it is no better for breathing pur-
poses than so much tar. After a baby
has spent a few months in a one-room
tenement breathing the air after six
or eight older people have been using

 

it and the sun has been frying it until
it has addlcd like an egg, the said
baby usually gives up in disgust and
goes to a country where harp music
is used in place of oxygen to sustain
life.

By long practice some people can
inure themselves to air which has not
been changed for weeks. However,
the same people can usually find com-
fort in a shirt which hasn’t been
changed for a year. Both habits are
uncleanly.

Americans are very fond of fresh
air and consume enormous quantities
of it, not only at baseball games and
at the seashore, but on golf courses

Electricals inspect
Largest Switches

The senior electricals last Friday
visited the Delta Star Manufactur-
ing Company on their latest inspec-
tion trip. The trip was under the
direction of Professor Nash, and
consisted of the inspection of the
world’s largest electrical switches.

These switches are to be used on
the transmission lines from Boulder
Dam to Log Angelcs. These trans‘
mission towers have a crossbar
which is sixty-four feet in length
carrying three tubular copper cables
32 feet apart The experimental la-
boratory of the company was also
taken in on the trip.

Mr. Young, the president of the
rmmpany. gave very interest—
ing; information to the electricals.
They were conducted through the
plant under the direction of Mr. F.
C. Van Eiten, a graduate of Ar-
mour, ’09.

and sleeping porches. A sleeping
porch is now used as a specific for
a large number of diseases and if its
popularity grows, the carpenters will
soon be riding in automobiles of Lin-
coln quality and the doctors will be
working for fifty cents an hour.
Fresh air strengthens the lungs,
purifies the blood, steadics the tem-
per, untanglcs the nerves, and braces
up the morals. The air in the home
should be changed at least once an
hour and the air in the theater should
he changed immediately after every
doubtful joke and suggestive song. If
the audience could be changed, too,
it would have a great influence in up—
lifting the stage. P. S.

 

 

, ' ‘Welborn Speaks

on Label Service

Labeling improves Quality
of Merchandise

Mr. Curtis E. Welborn, Super-inn
tendent of babel Service at Under-
writers Laboratories, delivered an
address last Friday on the Under-
writers' Laboratories Label Service.
While this service has been set up
[or the protection of insurance com-
panies to take care of certain hazard—
ous conditions, it also is beneficial to
the consumer, because it tends to in—
crease the quality of merchandise
put on the mark. This service or-
ganization is not a profit-making one,
but maintains itself by charges made
to manufacturers for labels and the
stock insurance companies.

Regulates Card Industry

A good example of its benefit to
industry is shown in the case of fluid-
ble electric cord mam‘ acturmg. In
1929, only 15% of the total amount
of flexible cord but on the market
was of good enough quality to stand
an Underwriters Laboratoreis’ test.
However, the Label Service was in—
troduced in this industry, and the
percentage of first class cord in ratio
to the total amount put on the mark—
et was raised from 15% to
85%. It also has been stated that
most of the remaining 15% is not
sold in this country but is exported.
Since the quality of the flexible
cords has been very much improved,
many of the former hazards have
been entirely eliminated.

Inspection Every Three Minutes

During the past six years there
have been 50,400 inspections made of
various products. If time is deducted
for Sundays, holidays, half days on
Saturdays, etc, this means that dur~

At the March 28 meeting of the
W. S. 19., Mr. Ernest E. Tupes spoke
on “Interesting Phases of Engineev
ing Law.” Mr. Tapes, a patent and
corporation lawyer, related some of
the building laws and ordinances
iby which the engineer must abide.

In building operations, it is the
duty of the engineer to supply lat-
eral support. for adjoining vacant
property to prevent settling of the
land. Should the land settle, the
engineer is liable to prosecution. If,
however, the neighboring property is
tenantcd, the engineer is not respon-
sible for any damages incurred by
adjoiningr structures, unless he can
be proved negligent.

Mr. Tupes further brought out
that in the resurvcying of property,
old surveys have preference to new
onus, unless the new surveys super»
sede the old ones. Should it happen
that a. building is out of line, the
owner of the building must either
move his property on line, or buy
the excess strip of land at a price
fixed by court.

Mr. L. T. Condon, a consulting
engineer, is to be the speaker at
the next W. S. E. meeting. So far
the ihject has not been announced.

are only a few things which have
been inspected by Underwriters’
Laboratories.
