OREGON STATE COLLEGE -Am
W) year-old woman who is in
leiesled in "keeping up with the
marvelous changes in America"
is taking a graduate cour.se in
home economics this fall at Ore
gon Stale College.
She is Mrs. Winifred Case Knapp.
r.ow of Cor vail is, who in 11)20 was
the lirst woman ever to receive
a master's degree in home eco
nomics from University of Minn
esota. The course she is taking is "Hc
icnl Advances in Foods."
Next quarter or in the spring.
.'Jie plans to lake some advanced
work in weaving. Mrs. Knapp has
u small loom in her apartment
mid she makes some of her own
di-csscs and jackets. She earlier
look some classwork in weaving
in I'M.
The foods course this full is
just "for my own edification," she
noted. "One of the rewards of liv
ing is watching change and pro
gress." Mrs. Knapp uses a cane to help
gel around the campus but is regu
larly among the first students to
arrive in the classroom each Mon
day, Wednesday and Saturday at
a hi.
OSC's school of home economics
is observing its 70th anniversary
this fall. Interestingly enough, the
difference in age between Mrs.
Knapp and of the 18-year-old
freshmen coeds who walk the halls
with her is that 70 years.
A widow, Mrs. Knapp lives alone
in a small apartment near the
campus. She chooses to live alone
because "1 like to be independent."

checks, according to a recent an
nouncemcnt.
The work accomplished to date
is the first phase of an overall
automation program adopted by
the district's board of directors
and designed to' improve water
service, operating efficiency and
to reduce structure operating
costs.
A romote control system is used
to control water inflow in the J
canal at the Lower Lost River
diversion dam, located three miles
south of Merrill. The system is
operated over the Columbia Util
ities telephone line. The district
receives information or moves the
motorized gates at the dam lo
cated seven miles from district
headquarters by first dialing the
telephone at the dam. This ring
actuates the telephone answering
relay which automatically answers
the ring and completes the cir
cuit to the remote equipment. Pow
er to the remote unit at the of
fice is then turned on sending an
audible steady tone across the
phone lines which is picked up
by a tone receiver at the dam.
Through the use of three tone
channels (three tone transmitters
generating and transmitting tones
and three tone receivers operat
ing at differet frequencies) it is
possible to read water gate level
information and to open or close
the gales. When the operation is
finished this system automatically
hangs itself up ready to answer
the next call.
To make this system operate
it was also necessary to mechan
ize the existing gate hoists with
three one half horsepower gear-
motors with chain and sprocket
drives, three safety limit switches,
a single magnetic reversing mo
tor, starter and miscellaneous wiring.
The automatic checks installed
in the district's J canal just
downstream from the diversion
dam are employed to keep a con
stant waler level up stream from
the check providing a steady wa
ter delivery to the water users
ibove the check and to the lateral
canals feeding off the J canal.
The motorized gates simply auto
matically move upward if water
level is too high or downward if
waler level is too low. This elim
inates water fluctuation in the ca
nal. The hand operated gates on the
checks first were electrically con
trolled. This was done with the in
stallation of a quarter horse gear
motor in a central pier between
two radial gates, driving both gates
in the same direction. By mov
ing the gates at slow speeds the
chances of a gate "hunting" (con
stnntly seeking a position) were
substantially eliminated. The dis
trict used floatlcss electrode type
control switches located immed
iately above the check in a still
ing well set up to keep the wa
ter level above the check within
one inch of where it is set. Rotary
limit switches were used to pro
tect the gear train.
Irrigation District Manager M.K.
StinnU and his assistant, Edwin
V. Lance, designed both systems
of control. Those connected with
the operation of the remote and
the automatic system have found
them to be a simple and reliable
system. It has also proven easy
to maintain.
