Bombers from the bottom of the Deep Blue Sea THERE 'S a fabulous amount of magnesium in
everyr cubic mile of sea water. Enough magnesiurm for more than four million Flying Fortresses. Enough to lay a continuous ceiling of bombers .. . a hundred miles wide and stretching all the way from London to Berlin!
Now magnesium can't be dredged out of the ocean ... for every ounce of this rare metal must be produced by electrolysis. This necessitates the conversion of vast amounts of alternating current to direct current, at; the very water's edge.
The best means of converting power is the mercury arc rectifier. As long as ten years ago, Westinghouse Research Engineers began experi- mental work on a new type of mercury arc rectifier which would be more efficient ... more economical . . . less costly to install and maintain than existing types.
The Ignitron operates on the radically new principle of starting and stopping the mercury arc with each cycle. This means that electrodes can be placed much closer together . . . grids and shields reduced ... arc drop voltage decreased. . .
voltage control simplified ... are-back practically eliminated. And all of this assures higher effi- ciency and greater reliability.
More than 1,000,000 kw of Ignitrons are now at work . . . in magnesium, aluminum and chlorine plants, in electric railway systems, in mines, in war industries of many.types.
And so, the germ of an idea .. . born ten years ago in the Westinghouse Electronics Laboratories . is now contributing its important share in
winning the war today.

A New Star over America THIS is the new All-Navy "E" burgee. With its
added star, it signifies that, for a period of over
six months, production of Navy material has been
apace of schedule. First flown in America over the
Bausch & Lomb plant, it is official Navy recogni-
tion to B&L workers of their continued achieve-
ment in Production for Victory. It replaces the
Bureau of Ordnance flag and "E" pennant awarded
Bausch & Lomb July 25, 1941.
The Navy "E" has always been an honor to be
striven for, to be guarded jealously. On gun turret,
battleship funnel, or the flagstaff of an industrial
plant, it is a symbol of championship performance. But today, Navy officials-and the American
public-are anxious to see this award in as many
places as possible. Because "championship per-
formance" is what America, needs today-all down the line.
Workmen at Bausch & Lomb are devoting to the
specific implements of war, the experience and skills gained in the production of scientific optical instru- ments. Today the world depends on America's men-behind-the-men-behind-the-guns to destroy the forces of aggression-that the ideals of individ-
ual freedom may survive.
