AIRCO NITROGEN HELPS GIVE US EYES TO PIERCE THE ARCTIC NIGHT

Faultless eyesight for America’s Ballistic Missile Early Warning System depends on germanium diodes — tiny signal filtering “optics” for the data processor which are made by Clevite Transistor, Waltham, Mass. These germanium crystals are grown in a furnace atmosphere of nitrogen, and they must be of the highest quality.

Control of this quality in diode manufacture requires that the delivered gas be of utmost purity; and that this purity be held all the way from the liquid nitrogen receiver to furnace. An impurity of even a few parts per million in the nitrogen, and entrapped in the furnace-grown crystal, could cause miles of error in a field calculation.

To help make certain of the highest possible quality at the lowest possible cost, Clevite developed a gas monitoring system which Airco engineered and built to Clevite’s specifications. The resulting system is so precise that it keeps watch on the purity of the Airco nitrogen right to the furnace entrance.

In every industry today, modern Airco processes based on gases are improving quality, boosting production, reducing costs.

Airco gases can give you heat… cold … special atmospheres… or can act as a raw material for a chemical reaction.
