Experiments High

To Prevent Metal Rust

British Scientists have just announced important develop- ment in these experiments on prevention of rust in metals. Discovery has been made at the Department of Scientific and In-

dustrial Research.

During the Wor solution of slum benzate WOR used for ensuring that water in car radiators did not freeze in cold weather. It was also found that when added in smail propertions ta glycerine the mixture so ob- tained prevented corrosion or metal parts

was that spray formed a coating which could easily be stripped off when no longer required.

This new liquid preservative will be invaluable for protecting metal surfaces of machines against rust during transport or when in storage.

Locomotive For Work Underground

A Glasgow locomotive firm which has been building rail- way engines for more than 100 years and is still building en- gines of all sizes, has just put into large scale production a 100 horsepower diesel locomo- tive for underground work smaller for type and

power than any yet made anywhere in the world..
