Technology Notes

> The principle of automatic heat control, now used in electrically heated flying suits, has been applied by General Electric Co. to a bed blanket which looks, feels and launders like any cotton-wool blanket, but carries a low-voltage current which can be set to maintain any desired temperature without regard to weather changes or home fuel shortage.

> The "electric eye" has a new use in protecting ships at sea from submarines. An electronic tube mounted in the ship's funnel warns the engine room whenever poor combustion allows smoke to form, thus prevents the black plume which reveals a ship's position far below the horizon.

> An office composing machine, which operates like a typewriter but can take a sheet 20 feet wide, has been developed by the Ralph C. Coxhead Corp. to enable a typist to letter engineering drawings and tracings. By reducing to one-tenth the time required for lettering, it cuts down drafting-room time more than one half, solves a bottleneck in war production.

> An automatic ice indicator has been developed by the Minneapolis-Honeywell Regulator Co. at the request of the Army Air Forces. The new ice indicator does two jobs: it shows on an instrument panel the thickness and rate of accumulation of ice on airplane wings, automatically operates the deicers at the proper time.
