Just six months after television's
official introduction to the American
public at the opening of the New
York World's Fair, Ann Arbor will
be given a full-scale reproduction of
television broadcasts in Hill Audi-
torium Friday.
The demonstration 'roadcast and
reception to be presented here by the
Radio Corporation of America under
the sponsorship of the engineering
college and the Detroit section of the
Institute of Radio Engineers will fea-
ture the cathode ray receivers which
made the spread of television pos-
sible.
Cathode Ray Tube
The cathode ray vacuum tube is a
funnel-shaped glass tube with a flat
screen at the large end. The picture
is projected upon this fldurescent
screen by a fast-moving beam of elec-
trons which lights-up successive spots
on the screen in varying intensities
to correspond to light or dark spots
on the actual picture. Because the
human eye tends to keep each ,image
for a fraction of a second, the suc-
cession of dots created the impres-
sion of a complete picture in much
the same manner that a series of pic-
tures produces the effect of motion
pctures.
Beam Shot Out
The beam, which is shot out from
the small end of the cathode ray tube,
travels back and forth and up and
down over the area of the screen,
covering it in a series of 44r horizon-
tal lines. The whole screen is thus
covered at the rate of 30 frames per
second, but as even this high speed
tends to produce a slight flicker ef-
fect, engineers have devised a scheme
to fool the eyes. Instead of scaning
successive lines of the picture, the
beam covers first the even, then the
odd lines, thus traversing the pic-
ture twice for every complete im-
mage formed, and giving the impres-
sion of 60 frames per second.
Receivers to be shown here: will re-
semble an ordinary console radio in
outward appearance,' except for a
mirror, set at an angle to the top of
the set, which reflects the screen
image to the spectator. These re-
ceivers will be the largest model now
in production, and' will form images
approximately' 8 inches high and 12
inches wide..

KYER LAUNDRY

AND We strongly suggest that you use the Student "ROUGH
DRY" Bundle, in which Shirts, Handkerchiefs, and Socks are com-
pletely finished to please the most critical... Underwear and
Pajamas are washed and folded ready for wear - all at the modest
rate of ten cents per pound, with charges for extra finished laund-
ry marked accordingly.
THE TRUCK will pick up your clothes immediately and deliv-
er them within two days. Yes, having your clothes laundered here
in Ann Arbor certainly does save you time and trouble; but better
yet, it saves the expense of mailing your things back and forth
and the effort some one has to go to at home to get them ready
for you.
