Factory's record output

World production records for high-speed diesel engines are being set up this year by a Peterborough (East England) factory which had its afficial opening recently. Output is already at the rate of 25,000 engines a year and 85 per cent of these are going to overscas markets.

Sections of the factory are working day and night to keep up with the huge home and overseas demand and in the past few weeks alone the pressure of work has been intensified by substantial orders book- ed for Canada, Belgium, Argentina and a £1 million contract from India.

Castellated

beam system

An important recent develop- ment in steel construction, which has attracted considerable atten- tion among structural engineers both in Britain and abroad, to the castellated beam system by which steel beam of increased strength is bulit up from a standard beam by a combination of flame-cutting and electric-welding, without a corresponding increase in weight and without waste of material,

The process was initially de- veloped by Mr. G. H. Boyd, and the beams were originally The known as Boyd beams. patent rights have now been faken over in their entirety by the Appleby Frodingham Branch of The United Steel Cos., Ltd., and the beams are now known as the Appleby-Frodingham Castellated Beams.

Flame-cut profile

A castellated beam is built up from a standard British rolled section by flame-cutting the web in a pre-determined profile which has been mathematically calcula- ted.
