Even the Oxford English Dictionary cites 1812 as the first instance of the word in print Gradually, the road leads back to the mention of a turnscrew, the word for a screwdriver in the Midlands and North of England. Since this is a literal translation of tournevis, the French for screwdriver, the author consults Diderot and d''Alembert''s Encyclopedie, where he finds several screwdrivers. We are now back to 1765, and shortly to 1723, the date of the first known mention of tournevis. "Davisco pushed us, quite honestly," allows Jack Jordan, president of Sudmo. "Somebody had to sit down and redesign a valve to handle particulate, and that''s a big challenge. But the ability to handle particulate up to 1.5 inches opens up complete new markets for us." Fruit for yogurt, soups and pet foods are among the processing segments evaluating the technology.Another innovation that must pass sanitary muster before it can find wide application in food processing is the constant flow (CF) valve from GATE LLC. The valve was developed by John Newton, a Florida inventor and founder of Grand Banks Yachts, at the request of E.I. DuPont de Nemours to improve the accuracy of chemical spraying in agriculture. Accurate depositing is easy to achieve if pressure is constant, but that is not always the case. The CF valve offers a simplified design and preset calibration to precisely dispense liquids or gases.
