SUN POWER
BROUGHT
NEARER
Dr. Charles Abbott, of the Smithsonian Institute, demonstrates the solar
power machine, at the convention of the American Association for the
Advancement of Science. This newest sun-harnesser-the fifth in the line of
,solar engines constructed by Dr. Abbott—eliminates most of the serious
defects of the earlier models and brings closer the era when men will be able
to harness the vast energy of the sun to do his work. (Acme Photo)

Tubes with leaks in them, leaks so
Small as to elude human detection,
are rudely tossed to one side, and
those in a state of perfection are
permitted to pass. It is all done so
quietly, so efficiently, and with such
inexpensive and simple equipment
that one unaccustomed to the mir-
acles now being performed by elec-
tronic equipment would be utterly
astounded by the uncanny opera-
tion.
But what do we mean by electron-
ic equipment? It might be put this
way: electronic equipment? It might
be put this way: electronic devices
see, feel, and hear. The devices nec-
essary to perform these otherwise
strictly animal functions are called—
in the same order—photo-electric
cells, grid -glow tubes and vacuum.
tubes..
In the steel industry, there is the
Ail distinct possibility that one hundred
million dollars may be saved annual-
ly by the use of this "nothing inside
glass bottles," as one scientific wit
put it. It represents the amount of
money lost every year through im-
proper heat regulation for steel un-
dergoing certain treatment. The ap-
plication of electronics to this prob-
lem promises a far more effective
temperature control.
A manufacturer of paper contain-
ers sold his cutter cartons by the
pound, partly because of the great
difficulty of finding a reliable mech-
anical device that would count them.
But the cartons were impregnated
with wax, and it was practically im-
possible to control this impregnation
to a point where a specified number
of cartons would have a specified
weight. Yet the purchaser, depend-
ing upon finding a certain number of
cartons to the package really order-
ed b ythe gross. To guarantee his re-
ceiving the proper number the man-
ufacturer always allowed ten percent
overweight.
A photoelectric counter, capable
of reaching a speed of 3,000 items
a minute, now counts the cartons
and saves the firm many thousands
of dollars annually.
Whether it is measuring the
amount of an invisible gas like ozone
or helping aviators to make a land-
ing during a heavy fog, electronic
equipment is faithful and accurate.

converting machinery, high-voltage
flash -overs in such equipment are
costly, and only a few seconds -are
necessary to destroy many thousands
of dollars worth of equipment. By
Placing photo -electric cells near the
commutators of electric generators
and converters, flash -overs are im-
mediately detected and the machin-
ery is cut out of the circuit before
great damage can occur,
The meaning of electronics to the
power industry is far greater than
this, however. This new science,
through the 'use of the tube known
as the thyratron, will eventually
save the power industry many mil-
lions of dollars annually. The thyra-
tron, purely an electronic device,
promises for the first time in the his-
tory of the power industry, to en-
able the transmission of high-voltage
direct current instead of the hitherto
alternating current.
In the weaving of fabrics, the first
application of the photoelectric cell
was in the comparison of dyes and
the color of delicately shaded fabrics
where it was impossible for the hu-
man eye to distinguish differences.
Now the photoelectric cell threatens
to enter the sanctum of the loom.
The invention relates to a method of
producing Jacquard weaving cards.
The design to be woven into the fa-
bric is first placed on a card in the
form of a series of holes. After holes
are punched in a tape the photoelec-
tric cell controls duplication of these
holes in design formation on the
Jacquard cards.
Although the industry is still very,
very young, we find no less than one
thousand two hundred different ap-
plications of electronic devices. A.
wit has said that the new industrial
god is electronics and that the vac-
uum tube is his messiah. It is one
thing to devise an automatic machine
with purely mechanical parts and.
quite another to endow that machine
with almost human attributes, with
senses of feeling, hearing, smelling.
and seeing. For the first time in the
history of man, the human senses
can be duplicated by mechanical con-
trivances.
Those not familiar with electronic
equipment may wonder how it is that
a tiny glass tube like a photoelectric
cell can be brought to operate as a
control. It actually only supplies the
impulse that results in control. The
total electric energy coming from the
cell will amount at best to but a few
millionths of a watt. It would not be
sufficient to operate anything but
one of the more sensitive electric
meters. Hence, the electric energy
emanating from the photo -electric
cell when it is struck by light must
be amplified, and this is accomplish-
ed with one or two vacuu` tubes.
Even then, there is very little cur-
rent to be had, no more than enough
to close a small sensitive relay or
operate one of the electronic 'trig-
gers" like the thyratron, another
vacuum -tube electronic device. Thus
by such means, large 'amounts of el-
ectric energy can be released by tiny
whiffs of energy for the control of
machinery.
Some idea of the effectiveness of
such control may be had when it is
known that the newer rolling mills
in the steel industry are electronic-
ally controlled. The huge billets of
hot steel must scamper back and
forth under the rollers during the
operation, and such movements used
to place tremendous mechanical
strain upon the mechanism involved.
In the baking industry, the photo-
electric cell, or electric eye, as it is
perhaps more commonly called, is
installed in ovens used to bake zwie-
bacli or melba toast. Electric eyes
control oven heatingcoils in such a
way as to eliminate both over- and
under -done bread.
Some idea of the momentous fu -
tare of the new -art may be had from
news reaching this country from Rus-
sia. Russian engineers have perfected
a new automatic metal -turning lathe
controlled by blueprints. The special '
drawing which details the dimensions
of the particular piece to be turned is
Ted to an electronil; scanning device
connected electrically td the lathe to
be used. Control switches click and
the machine sets about cutting metal
to size. The control mechanism may
be used on one lathe or on a dozen:
of them working simultaneously,
Electronics now stands where elec-
tricity stood sixty years ago.
Practically all the newer elevator
installations have been supplied with
photo -cell leveling mechanism. No
longer does the operator need to
manipulate his control lever back
and forth to bring a car to a level
position. This is done automatically
by little glass bulbs secreted away
in the floor of the building and the
car.

mutual acquaintance who has just joined up catches the eye of Sapper Tom
Miller (left) and Corporal Dick Donald, both of Oshawa, in the top picture.
Below, three of a kind, all gunners and all from Timmins, Ontario, get in a
huddle over the latest copy of ' their favorite reading. From left to right
