In April of 1991, the U.S. National Aeronautics and Space Administration concluded that o2one depletion was occurring even faster than had been estimated, and at the third meeting of the patties to the Montreal Protocol in June of 1991, an eadiet phaseout of controlled substances was proposed. An assessment of the technical and economic consequences of a 1997 phaseout is cuttendy underway, and further acceleration of the phaseout schedule to as soon as 1995 seems likely. Many countnes already have undatetaHy banned or curbed the use of controlled substances well ahead of the Montreal Protocol timetable. As of eadyjuly 1992, there were 81 parties to the Protocol. 

The principal uses of PCTFE plastics remain in the areas of aeronautical and space, electrical/electronics, cryogenic, chemical, and medical instmmentation industries. AppHcations include chemically resistant electrical insulation and components cryogenic seals, gaskets, valve seats (56,57) and liners instmment parts for medical and chemical equipment (58), and medical packaging fiber optic appHcations (see Fiber optics) seals for the petrochemical /oil industry and electrodes, sample containers, and column packing in analytical chemistry and equipment (59).

A smaller factor in ozone depletion is the rising levels of N2O in the atmosphere from combustion and the use of nitrogen-rich fertilizers, since they ate the sources of NO in the stratosphere that can destroy ozone catalyticaHy. Another concern in the depletion of ozone layer, under study by the National Aeronautics and Space Administration (NASA), is a proposed fleet of supersonic aircraft that can inject additional nitrogen oxides, as weU as sulfur dioxide and moisture, into the stratosphere via their exhaust gases (155). Although sulfate aerosols can suppress the amount of nitrogen oxides in the stratosphere...

Since World War 11, the U.S. space program and the military have used small amounts of insoluble chromates, largely barium and calcium chromates, as activators and depolarizers in fused-salt batteries (214,244). The National Aeronautics and Space Administration (NASA) has also used chromium (111) chloride as an electrolyte for redox energy storage cells (245).

The Montreal Protocol of July 1987 resulted in an international treaty in which the industrialized nations agreed to halt the production of most ozone-destroying chlorofluorocarbons by the year 2000. This deadline was hastily changed to 1996, in February 1992, after a U.S. National Aeronautics and Space Administration (NASA) satellite and high-altitude sampling aircraft found levels of chlorine monoxide over North America that were 5i % greater than that measured over Antarctica. 

The equilibrium solubility of common inorganic gases in petroleum liquids can now be estimated by nomograph. The relationship is based on an earlier correlation established by the U.S. National Aeronautics and Space Administration and the subject of a standard method approved by the American Society of Testing and Materials.

New machining techniques are constantly being introduced. Conventional workpiece materials have improved progressively through close control of manufacturer and heat treatment, and new materials have been fostered by the aeronautic and space industries. The results have been ever improving output, dimensional control and surface finish. The continuous development of cutting fluids has enabled these increasingly severe conditions to be accommodated.
