vets with dependents, and $10 addi»
'ional monthly for each child.

ln order to secure the passage of
”this bill the Vets Club is cooperat-
xlng with The Intercollegiate Vet~
eras Coordinating Committee. This
committee is compoeed of 55 col-
lege; veterans chills throughout the
coat that have united to give n
stronger voice to the student vet-
'canno. So that complete support can
film given lo this project the Vets
I lulu will distribute petitions and
nestionnaires which all veteran
‘stndents should secure. The ques-
J ionnairos are. so worded as to give
o, complete break down of the vets,
which will give more
vciglnt to the petitions. The peti-
lons and questionnaires may lie so-
ured at the booth in like lobby of
£16} Student Union.

Bill McDonough, a member of the
lob, spoke on the organization of a

Mr. Hand and Mr. Dealiins, repre-
entativcs of the Veterans Admirals»
"ration here at IIT, were present
t the meeting and stressed the im~
)ortancc of organizations to veter-
ans. ”A tutoring service for dis—

The announcement emphasized
that membership in the new Naval
Reserve will not change a. man’s nor-

 

mal living conditions; it allows him
to maintain a rate in the Navy and
build up time for credit towards in
«creased pay, yet live” the life of a
civilian. He may decide to attend
meetings once a week, or he may

 

  

decide to simply be a member of the

In no case, in time of peace, will :5.

The fraternity endorsed the sug-
gestion to have the Recorder’s Oli‘lee
list the students’ overall average
and rank in class and department
on his transcript. In the past, scv»
oral worthy IIT students, who were
not elected to honorary fraternities
because of lack of activities, have
been overlooked in consideration for
scholarships. It was felt that listing
the studnet’s rank and average on
his transcript would aid in the evalu—
ation of his value by interested par-
ties. The sugg'eotlon will be sub-
mitted to the Faculty Council.

It is a otnmgo fact thin the ninth most
prevalent element on the cavtlx’o crust
should have lucen legal-dad an "taro”
for over a hundred years after ito dio—
covcry in 1791. But that is the otory
of titanium, actually more abundant
than zinc, copper, lead, tin, and nickel
combined. One of the factors that have
kept titanium from lacing better known
is the difficulty of handling some of its
compoundo commercially.

if, as a student, you were to look up
the equations for tho manufacture of
titanium oxide pigment, you might find
something like thin:

Fe'riog nFegosl-p (Sn +3)H250,-——n» 'msmm
+1”ch 'l- nFGa(SOe)u + (311 +3

Fmsom, + Zil‘ my» 2FeSO¢ + 15:80..
Tusom + (x+2)H20—mn> “0”);le + $12304
TiOszgO—mw'll‘mg + 311-320

*——The exact composition of ilmenito
varies with the source of the one.

From these equations, the manufoo
tore of the “wlllteet of White” pigmento
from black ilmenite ore appears to be
chemically simple and straightforward.
However, the processing required to
obtain indmtrial titanium oxide of
sufficient brightness, hiding power and
fineness is more complicated than once
would anticipate.
