Possibilities Of Producing
New Engine Are Small
During Present Crisis
Reported to be potentially the most
efficient and easily produced air-
plane engine ever made, a new motor
now being developed by Ford vice-
president, Charles E. Sorenson, has
little chance of being perfected in
time for use in the present emer-
gency, according to Prof. E. T. .Vin-
cent of the niechanical engineering
department.
Salient features of the new engine,
as reported in a recent article in PM,
include the exclusive use of cast
rather than forged, rolled or pressed
parts, a built-in turbo-supercharger
for high altitude flying and water
cooling instead of the usual ethylene
glycol.
Vincent Doubts Possibilities
But Professor Vincent is more than
skeptical. "Unless Ford has developed
a new aluminum alloy with, a marked
improvement in properties over ex-
isting cast alloys, there is no ad-
vantage in casting over the forging
process.
"It may be cheaper and a bit easier
to produce cast parts, but it takes
just as long, ad the loss in strength
in the major parts would make the
change very inadvisable," he said.'
An additional advantage of cast
parts, the article claimed, is that
when the cylinder, liners become worn.
they may b'e taken ou' anG replaced,
an operation much asier than re-
boring. .
Again Professor Vincent objected.
"That's nothing new; it was done in
the period of the first World War.
And it is very desirable to use all new
cylinders for military operations, as
that would also restrict piston rings
and other equipment to a standard
size."
New Alloy Needed
An alloy has been developed to per-
mit -the casting of satisfactory crank-
shafts and cylinders, he noted, but
unless Ford has found some new al-
loys for use in other parts of the en-
gine, it is extremely doubtful that
cast parts would give great weight
saving.
As for the turbo-supercharger, de-

engine at high altitudes, Sorenson
has nothing new here, it was pointed
out, as planes are already using this
apparatus. In fact, it was first used
in the last war, and most altitude
records have been established with it.
Sorenson's only change, then,
would be to have the supercharger
built in, and that would be a big mis-
take according to Professor Vincent,
as it would result in the ejection of
more heat into the cooling system
and necessitate a larger radi~tor
without increasing the engine's ef-
ficiency.
Questions Use Of Water
Another definite backward step, he
asserted, would be the use of water
instead of ethylene glycol as a cool-,
ant. "I would question the accuracy
of the article," he declared, "as I
cannot believe that Sorenson would
take such a definite step in the wrong
direction."
Water under pressure would be a
different matter, Professor Vincent
pointed out; but even then the weight
3f the radiator would have to be in-
creased to almost double its present
weight in order to stand the in-
creased pressure.

Dr. Panofsky
To Give Talk
Art Historiai Will Lecture
At Racklam Wednesday
Dr. Erwin Panofsky of the Insti-
tute for Advanced Study at Pinceton
will deliver "a University Lecture on
"Durer's Melancholia--the Concep-
tion of Melancholia in the Renais-
sance" at 4:15 p.m. Wednesday in the
Rackham Lecture Hall.
A recognized authority on the his-
tory of art, Doctor Panofsky was for-
merly professor of the history of art
at University of Hamburg. He came
to this country in 1934.
He has been a member of the
rPrinceton faculty since 1935, and is
the author of five books published in
Germany and several articles pub-
lished in this country.
The lecture, given under the aus-
pices of the Department of Fine Ares,
will be open to the general public.
Year's First Co-Op Party

year at 8:30 tomorrow evening in
the Women's Athletic Building.
In addition to social dancing, a
unique feature is to be provided in
the form of folk dances supervised by
students in the women's physical ed-
ucation department. Refreshments
will be served.
Members of all the cooperative
houses are invited to attend. There
will be no admission chaige.

Vie- For Ballot

Tuesday
Seniors
Position

Freshman and senior engineers
wishing to have their names placed
on ballots in the coming engineer-
ing class elections must have their
petitions in at the Dean's office, 255
West Engineering Building, by noon
Tuesday.
Senior class officers to be elected
the following Friday are president,
secretary, treasurer and Engineering
Council representative. The student
getting the next highest number of
votes for president will automatically
be made vice-president.
Freshmen, voting at their regular
freshman assemblies on Wednesday,
Nov.' 5, will elect two students as
frshman representatives on the En-
gineering Council.
All petitions must contain 25 sig-
natures from the applicant's class,
as well as state the applicant's qual-
ifications for office. Senior petitions
will specify which office is sought,;
election chairman Verne C. Kenne-
dy, '42E, announced.
Candidates for the senior offices
will not be announced in The Daily
until Friday morning, and no elec-
tieneering will be permitted near the
ballot box, to be placed in the West
Engineering Building over the Engi-
neering Arch.
Serving under Kennedy on the'
election committee are John Burn-
ham, '42E, David Wehmeyer, '44E,
and Don West. '4E.

Edward H. Deyo, '42F&C, has been
announced as the recipient of a Uni-
versity Scholarship in the School of
Forestry and Conservation.
Similar awards, each equal to one
semester's tuition, are offered in all
of the professional schools. Students
are chosen upon recommendation of
their teachers with scholarship, char-'
acter and general suitability being
the guiding factors.
