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). hey lfirgc T 31 NW FIRST VWRE HGHT1NG FOR >OUR U ff American Heart Association by Mbongon: N nerra Percy Mtw-a Barney Simon Oregon Affiliate, Inc.

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 ta rie s , a c c o u n ta n ts , tru c k drivers, surveyors, foresters, d ra ftsm e n , m apm akers and many other d is c ip lin e s , in c lu d in g law and p e rs o n n e l specialists. | j I J 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.
