Fruitful IC Institute

Pyongyang, July 12 (KCNA) — Scientists of the IC Institute under the State Academy of Sciences of the DPRK have given a good account of themselves in solving pressing scientific and technical problems.

Recently they have made an efficient portable welder.

The welder is an inverse transformation one, which is made of transistors with big output. It is applicable to any objects of the AC welder and DC arc welder.

It is light and simple to operate. And its welding quality is better than those of other kinds of welders.

The scientists have developed a device for reliably protecting electric motors from short-circuit and single-phase phenomena, over-current, fall of mains frequency.

They succeeded in developing cyanogen ion selective electrode and made a portable digital cyanogen densitometer.

The densitometer is capable of rapidly and correctly measuring the density of cyanogen ion in aqueous solution. It is applicable to automatically controlling the process of using cyanide.

Induction furnace protection system made by the scientists also is paying off at production sites.

The protection system has been applied to low-, medium- and high-frequency induction furnaces, preventing various accidents and saving a large amount of funds.
