claimed to increase the life of bearings by up -to 30 times has been invented by an Edinburgh 'engineer, Mr. John McGregor. Proprega, Ltd., Dundee. who have pioneered the invention, say that a firth of vehicle operators who applied the process to a new engine found • that after 40,000 miles the engine • still had not run itself in.
German, • European arid world rights for the process have been sold to a.group of German industrialists, who have the backing of six of Germany's biggest engineering concerns. Three • companies are being formed, but the British rights will be retained by the Dundee concern, who also keep a 50 per cent. share in the world company.
It is stated that the secret of the process is not so much in the chemical, which reduces friction, but in the additive witii the strongly adhesive. 'property, which ensures that the. anti-frictional coating will stay put under the most adverse cOoclition. It is' claimed that friction on metal and other surfaces is reduced by as Much as 80 per cent. •
A Dundee haulier, who tested the process, reported a 10 per cent.. increase. in the pOwer of his oil-engine, and a 123 per cent. saving in fuel. Mr. McGregor estimates that' engine life can be increased by five to 10 times normal expectation at.
cost of 120 if the engine is stripped.
