GOODRICH ANNOUNCES NEW PROCESS
Plating of Metal with Rubber May Aid in Development of
Frozen Confection Venders
Development of a new method! of forming
rubber compositions by the electrolytic dis
position or rubber from water has been an
nounced by the B. P. Goodrich Rubber Co.
The operation is called the anode process
and is shared by the Eastman Kodak Co.
and Anode Ltd. Use of the new method
enables the producer to produce a variety
of shapes otherwise difficult to secure and
eliminate the building up of layers of rub
ber by hand.
Research in the laboratories of the Good
rich Company has also brought out a way
plate metals, wood and concrete with a
covering of rubber, according to J. D. Tew,
president of the company. Mr. Tew said:
It was found that by heating rubber un-
er regulated conditions with suitable re
agent® a variety of modified rubbers could
secured, varying according to conditions
o preparation, from material similar to
a ata to hard, resinous products. When
Us«d as a cementing coat between rubber
and clean metal surfaces some o f these al-
, re^ mbber products were found to stick
e rubber firmly and permanently to the
metal.
Other means o f securing such adhesions
ad long been used, but the ease o f applica-
10n ° f the Culcalock process immediately
enarged the field of commercial applica-
ions of rubber-lined metal apparatus to
anks, pipe, barrels, chutes and other prod-
c s- It has been used to unite rubber to
Wood and to concrete. Rubber-dined tank
cars for transporting muriatic acid save a
Uf®r ° f 25,000 pounds of acid per month
a ut 40 per cent o f his cost through lower
reight rates and greatly rediuced labor
charges.”
Other developments indicated by Mr.
ew deluded the production o f a rubber
ompound said to be harder than steel and
more resistant to abrasion, and a fully vul
canized rubber which retains its flexibility

encountered by developers of ice cream and
frozen confection venders was that the least
bit o f moisture on the packages, or the
sweating of the packages in the vender,
caused them to freeze to metal parts con
tacted by the package. It was known how
ever, that the confections would not freeze
to rubber. Engineers of the Goodrich rub
ber company said that they could coat met
als with rubber, and now comes the inter
esting announcement of the perfection of
this process, along with other important
processes.
Some of the frozen confection venders
under development plan to use dry ice as a
refrigerant, which is proving highly ad
vantageous for this purpose. Now that
metal parts can be rubber plated, many of
the problems in the construction o f these
venders wil be greatly simplified and we
can be assured that inventive minds will be
quick to avail themselves of the use of this
new process.

The New York Times the other day
ran a heartening list of some 30 corpora
tions that had shown larger net earnings
in the first quarter of 1930 than in 1929.
Among them are such names as General
Electric, Bethlehem Steel, Allis Chalmers,
International Business Machines, General
Railway Signal, Sheffield Steel.
And along with these are United Biscuit,
Cream of Wheat, General Foods, William
Wri^ley, Jr., Curtis Publishing, Paramount-
Famous-Lasky.
Evidently the public that likes chewing
gum, the movies, crackers, breakfast foods
and popular magazines—and that public is
all of us—hasn’t stopped spending money.
