Tableware made "from plastics has practical advantages that
should assure it a bright future, according to Herbert S. Gauss-
beck, assistant chairman of chemistry and chemical engineering

at Armour Research Foundation.

Plastic cups, saucers, dishes, and
other dinnerware are stronger and
lighter than their china or earthen-
ware counterparts, Gausebeck
pointed out. They also hold heat
better and can be handled without
nurse.

. Restaurant owners and the plas-
tics industry developed the table—
ware to reduce breakage costs.
Most successful so far are articles
made of melanin formaldehyde
resin, at tasteless, odorless com-
pound with good impact strength
and resistance to abrasion. Poly—
styrene, polyethylene, and the
acrylic resin are also being used
for tableware items not exposed to
excessive heat.

“While plastic dishes cannot
equal the beauty of fine china,
they are well suited for every-
day use and for restaurants,”
Gausebecl: said. “They are
about one-third the weight of
comparable china or earthen-
ware, but their low thermal
conductivity permits food to
stay hotter longer."
Melanin-formaldehyde cups de—'

velop coffee or tea stains, but the
stains can be removed by bleaching
or a mild abrasive. The plastic
items cannot stand boiling in-
definitely, nor are they as hard as
china or glass and so pick up knife
scratches. One asset, however, is
the lack of surface glazing, which
often means unsightly cracks on
the surface of glazed earthen~
ware.

Improved designs for plastic
tableware, which allow better
stacking and a wide variety of
bright or pastel colors, promise to
make the lunch hour more cheer-
ful in restaurants and cafeterias.

“Polyethylene bowls are particu-
larly suitable for refrigerator stor—
age because their slight flexibility
makes water and vapor-tight
closures possible,” Gausebeck
said, “and because their inherent
chemical inertness makes them re—
sistant to all types of food so
stored.”

In addition to dinnerware, a
number of plastic table accessories
-—-trays, place mats, table cloths,
handles for flatware—are becom-
ing more popular because of their
ready cleansability and attraCtiVe
appearance.

Music broke forth in the North
and South Unions’ loudspeakers
this week for the first time since
June, 1948. The sound system had
been inoperative due to a broken
transmission line between the two
Unions.

The problem was tackled by stu-
dents Fred Wright, EE, Vernon
Keenan, Psych" and Joel Wexler,
EE, with funds authorized by
ITSA. The problem of repairing
the sound system involved innu»
mar-able hours of stringing wire
and the acquisition of a transfor-
mer whose impedance requirements
baffled the Rho Epsilon radio tech-
nicians for two semesters. Addi—
tional funds for improvements in
the system were requested at the

Roland A. Budenholzer, profes~

been named president of the
faculty club at Illinois Tech for the
coming year.

Other ofiicers elected were E. H.

gineering research at Armour Re-

dent; Henry C. Spencer, director of
the technical drawing department,
second vice president; Charles H.

Reservations for the Senior Farewell to be held June 8 are now on sale at the North Union ticket

booth. A maximum of 250 bids will be sold for the farewell, almost half of which have already
been reserved through the notice mailed to all graduating seniors. Any senior who is interested

in attending the affair and has not yet made his reservation should turn in his request at once

The farewell will be held at the
exclusive Tam O’Shanter Country
Club with dancing in the main
ballroom and on the outside term
races. Although the affair is
limited to 250 couples at present,
the second floor ballroom can also
be opened if the demand is great
enough.

Before the social committee can
justify the risk of reserving addi-
tional space, however, it must be
fairly certain that it can meet its
costs with extra bid purchases,
which means that the affair will
be planned only on the basis of
reservations made before the dead»
line. All reservations must be made
by February 24 and completely
paid by April 15. If any openings
are left after these dates they will
be sold at about $9 a bid.

At the last meeting of the social
committee, the controversial sub-
jects of dress and whether or not
to serve a dinner were decided.
Basing their decision on the

 

 

questionnaires mailed out, it was
decided to have the affair semi.
formal. (This was defined as formal
for the girls and dark business suit

or tux for the men.) Because of
the high price of a dinner, a more

reasonably priced smorgasborg was;

decided upon.

Research that produced an insecticide ante to snrny
on cows may onus millions tor linden-icon agriculture

Armed with only a fiy-swatter, the
farmer would get nowhere in ridding
his dairy barn of disease—carrying in-
sect pests. But he has to be careful
in using insecticides around cows. A
toxic spray may be absorbed through
the animal’s skin and show up in
meat, milk and butter.

Next fly-season farmers and
ranchers will be able to buy a fly—
killer that is both powerful and safe.
In Du Pont Marlate" 50% techni-
cal methoxychlor insecticide they will
get this combination of properties
that no single insecticide has ever

ofl’ered before.

Methoxychlor is a recent Du Pont
development. Du Pont scientists
worked for eight years in the labora—
tory and in the field to develop its
applications in agriculture.

A salien- insecticide

"Marlate" 50 is a residual insecti-
cide and remains an effective killer
of flies, mosquitoes, fleas and lice for
several weeks after application. VWien

exceptionally safe to human beings,

livestock, pets and crops. This has
led federal experts to recommend it
not only for spraying in barns, milk
houses and milk plants, but also on
the animals themselves.

Besides its use on livestock, meth—
oxychlor kills many insects that at-
tack vegetables, fruits and forage
crops. It is offered to flower growers
as an ingredient in Du Pont Floral
Dust. It is used in moth-proofing
compounds so that dry cleaners can
easily moth-proof woolens While
cleaning them. Many stores carry
aerosol bombs containing methoxy-
chlor for household use. It can be
used with safety in flew: mills, freez-
ing and canning plants, grain stor»

age elevators, cereal manufacturing
plantsmwherever food is processed.
This development of research can
bring immediate cash savings of mil—
lions of dollars to American agricul-
ture, industry and homes.

The: long tight

Exciting as the future of "Mandate”
50 appears, this does not mean that
the use of other insecticides will not
continue. Each has its special char-
acteristics, and each has special uses
for which it is outstanding. There
are at least 10,000 kinds of insect
pests, of more or less importance, in
North America, and there can be no
letwup in the scientific fight being
waged against them.

Du Pont alone now makes over
fiftydiii'erentinsecticides.’l‘heknowl-
edge gained inmaking each one speeds
the development of the next. By
backing ideas with funds and facili—
ties, Du Pont helps the farmer put

more and better food on the Ameri-
can table. At the same time, in many
other fields, Du Pont is helping to
raise the American standard of living
with continuous research aimed. at
developingnewproductsand improv-
ing present ones.
