In 1975, the Dürr 1330 X-ray film developer reached the market. This enabled the complete automation of the X-ray film development of all dental formats. The first foreign company branch, Dürr Dental France, was opened in 1977. The year 1978 saw the transfer of the US activities to the Joint Venture Air Techniques in Hicksville, New York.
A common theme among these techniques is the use of a fine (10 0 –10 −3 Torr) or high (10 −3 –10 −6 Torr) vacuum to remove air, and the use of an inert gas: preferably argon, but often nitrogen. The two most common types of air-free technique involve the use of a glovebox and a Schlenk line, although some rigorous applications use a ...
The main techniques associated with the use of a Schlenk line include: counterflow additions, where air-stable reagents are added to the reaction vessel against a flow of inert gas; the use of syringes and rubber septa to transfer liquids and solutions; [6]

Modern air pollution measurement is largely automated and carried out using many different devices and techniques. These range from simple absorbent test tubes known as diffusion tubes through to highly sophisticated chemical and physical sensors that give almost real-time pollution measurements, which are used to generate air quality indexes.
Midmark Corporation is an American company that manufactures medical, dental, and veterinary products and provides related services. It is a privately held company, and was founded in 1915 as The Cummings Machine Company.
