Growing Association With Indus
try VIII Be Shown

The enormous expansion of re
search in chemistry and this sciences
growing association with industry
will be revealed in papers, exceeding
in number and variety those of
previous years. to be presented at
the spring meeting here of the
American Chemical Society April 81
10 26. according TO the program an
rouncement received from New York
headquarters yesterday.
OF the many papers to be present
cd which will be OF interest to the
general public is one by the General
Motors Research Corporation, which
will detail an outstanding develop
ment in the field of combustion chem
istry which brought very practical
results for the motor-driving public,
the society announced. 1t was found
that when a small amount of tetra-
ethyl lead. about one-tenth per cent
was added to gasoline, the motor
knock which an engine exper' ences
when it is laboring uphill with the
throttle wide open is entirely elm
mated. Its greatest advantage is
said to be that it will enable eng ne
builders to construct motors capable
of withstanding very high compress
sion. probably double the present
compression. When this is done it
- possible to get almost double
mileage out Of the same amount of
gasoline, it was added.
Heat Tr,nsfer Symposium.
The convention will open Tuesday
with & heat transfer symposium,
which will continue through part of
Wednesday. Some of the subjects to
DO considered by leading authorities
are loss of heat from furnace walls,
heat transfers from bare and in
sulated pipes, loss Of heat through
bu lding walls, exchange of heat in
cvaPcratorS and factors effecting the
return, convection of heat in gases
and LIQUIDS, air blast heaters and
best operating conditions for pipe
heating and cooling equipment
Topics of wider scope will be pre-
sented Thursday. and will include
such subjects as the concentration of
iron by ferro- silicon, the soIubility of
agents, the efficiency Of fractionating
columns, IeWelry soldering, CONNER
ciai methods for melting platinum for
ieWelry purposes, corrosIon tests.
conditioning of boiler water, plati-
mum stamp law. effect of soluble in
organic compounds on cement, and
submerged corrosion of steel
Friday there Will be short talks by
the heads of various government
laboratories dealing with some of the
newer and less known activities re-
lating TO industrial chemistry.
Convention Week Topics.
In the afternoons during the con-
vention week various excursions
will be arranged so that the indus
trial executive and chemist will have
an opportunity of visiting the various
governmental laboratories, the work
Of which relates in almost number
less ways TO the various problems
that confront chemical industry.
Tuesday afternoon, april %, the
division Of chemistry Of medicinal
products. one of eighteen divisions
and sections of the society. will bring
20 light recent work in gland prod
nets, synthetic mediCinals and vita
mines Papers will he presented by
DR.. John j. Abel of the department
OF pharma cology, Johns Hopkins Uni
verSiry: Dr. c. II. Cloves, director of
the lilly research laboratory; f.. =.
White, Baltimore and Atherton Sci
deli. hygtenic laboratory, L. S. public
health service.
Then will come discussion by the
rubber division to be followed Wed
nesday by the program of the paint
and varnish section, which will con-
tinue through Thursday morning.
Following this section will be the
program of the division of water
sewage and sanitation and then the
sugar division will take up subjects
distributed between the chronological
and purely scientific aspects OF the
sugar industry.
CeIIuio~e Division Exhibits.
The cellulose division plans to make
exhibits of typical samples Of the
various products obtained from the
raw material from which the product
IS made and the general method used.
Under the pulp products division
there will be samples of crude and
bleached pulp from each of the sew
eral commercial pulping processes
and then the various typical papers
and paper products which are made
by various combinations of these
pulps, The list of paper specialties
contains many noval products such
as paper twine, paper burlap and
paper dish rags. Samples of a new
Kind of pulp recently developed by a
neutral sulphite process, also will be
displayed
The gas and fuel section is next
IN line and will he. concluded with a
round table discussion on Coal Con-
stitution and Classification" and
Spontaneous Com bustion of Coal
The program will conclude with
u discussion OF the developments in
production Of heium research work
on lubricatinE oils and discussion
ot the cracking method of producing
gasoline from petroleum. and a new
method of refining gasoline which
cheapens the method of refining in
some instances.
