In 1846 Norbert Rillieux of
New O rle a n s p e rfe c te d a
vacuum pan that revolutionized
the sugar refining industry in
America and Europe (Dec. 10,
1846, Patent No. 4879).
Dr.
Charles Browne, sugar chemist
of the U.S. Department of Agri
culture, said “ Rillieux's inven
tion is the greatest in the history
of American chemical engineer
ing, and I know of no other
invention that has brought such
a saving to all branches of
chemical engineering.”
The
principles involved in this inven
tion laid the foundation for all
modern industrial evaporation.
Rillieux, born in 1806, became at
age 24 an instructor in applied
mechanics at L’ Ecole Centrale
(University) in Paris and publish
ed papers favorably received all
over Europe.
Refrigeration and Agriculture:
Today’s version of the refri
gerated truck and the refriger
ated box car (Dec. 7, 1954, Pa
tent No. 2,696,086) were in
vented by Frederick McKinley
Jones, the first Black member of
the American Society of Refri
geration Engineers. The food in
dustry and agriculture of the
world was revolutionized by his
inventions. This innovation not
only permitted California and
Florida to become the twin
citrus captials of the world
(fresh vegetables included), but
also enabled the meat packing
industry to ship fresh meats to
distant marketplaces. In thirty
years this invention of Jones
has increased the value of
related industry and agricultural
land by many billions of dollars.
Jones also invented the auto
m a tic
t ic k e t
d is p e n s in g
machine (1939), and a two-cycle
gasoline engine (1950).

Smoke Jumpers:
During the early years of
World War II, a battalion of Black
airborne troops from the South
were the first men to train in the
art of parachuting into otherwise
in accessible areas to fig h t
forest fires (1942-1943). They
were based at the Cave Junction
Ranger Station on the Southern
Oregon coast.
Later, Native
Americans of Arizona and New
Mexico learned the technique.
In the ensuing decades this in
novation has enabled the U.S.
Forest Service to save billions of
dollars of timber that otherwise
would have been consumed in
major conflagrations. In 1976
the ranger of this district sent a
faded photograph and a 1943
news article about these pioneer
jumpers to a professor of Black
Studies at Portland State Univer
sity.
Minority Scientists, Engineers
and Technicians (NAACP)
In 1978 this region (6) of the
U.S. Forest Service contracted
with a local m inority consultant
to design and implement its par
ticipation in the national con
vention of the NAACP, which
was held in Portland, Oregon
that year. This as the first time
that the Forest Service had been
an integral part of the national
convention of a major Black or
ganization — a process that has
been followed on these past ten
years. A direct result has been
the nation-wide employment of
hundreds of Black scientists,
engineers, technicians, secre

Sealants Safeguard
Children’s Dental
Health
A simple, painless office pro
cedure has been proven effec
tive in preventing tooth decay in
children, reports the Multnomah
Dental Society.
This breakthrough in preven
tive dentistry is known as "p it
and fissure sealants."
Tooth
sealants — tough acrylic resins
bonded to the tooth surface —
may someday eradicate tooth
decay in children.
When a ch ild ’s molars are
developing, natural grooves and
depressions form on the chew
ing surfaces. Bacteria and food
particles collect in these "p its
and fissures,” and are d ifficu lt
to remove even with conscien
tious brushing.
As a result,
more than 80 percent of decay in
children’s teeth occurs in these
areas.
Using the same procedures
implemented in cosm etic bond
ing, dentists apply sealants to
the tooth surface, creating a
hard, long-lasting physical bar
rier between the tooth and the
cavity-causing bacteria.
Thi<
procedure has been found most
effective when the sealant is ap
plied to the first and second per
manent molars soon after they
erupt, usually when a child is
between the ages of six and ten.
The process of applying sea
lants is quick and painless.
First, the dentist applies a mild
acid solution to each tooth to
roughen it slightly. The liquid
plastics are layered over these
surfaces and hardened to form a
tough protective shield. Each
tooth can he sealed in just a few
m inutes, w ithout (h illin g or
anesthesia, and the sealant
usually remains firmly fused to
the tooth's chewing surface for
many years.
Food and bacteria are not able
to penetrate the bonded surface.
As long as the plastic material
remains in place, the tooth's
chewing surface is protected
from decay-causing agents.
Sealants not only prevent de
cay, but also arrest the deve
lopment and spread of early rh
cay that may be trapped beneai! •
the sealant. Research shows
that as long as the sealant pro
vides a sound physical barrier
between the beginning cavity
and its surrounding environ
ment, the cavity w ill not In
crease in size and the bacteria ir
the cavity w ill eventually die oft
ending the decay process
A growing number of scie n ti
fic studies attest to sealant; ’ p*
fectiveness.
One seven ye<
study of 400 schoolchildren pro
vided conclusive evidence that
sealants are nearly 100 percent
effective in preventing decay as
long as they remain bonded to
tooth surfaces. If a tooth loses
all or part of its sealant coatino,
the chances of its deveU-i
cavity are about the same c
the tooth had never been s alt
The Multnomah D edal ' o c
ty recommends pit and fissL
sealants for children as part of a
total dental care program that in
cludes daily use of fluorides,
daily brushing and flossing,
regular dental checkups, and a
diet that lim its snacks. Working
to g e th e r ,
th e s e
p o s itiv e
measures can result in a lifetim e
of strong, healthy teeth for all of
our children.
