MACHINES SUCCESSFUL

Owing to the restricted size of the Swiss home mar-

kot, by far the biggest part of the Swiss-mado

The wide use of these machines in all industrial countries shows that the goal aimed at has been reached.

The high necuracy of MAAG gear cutting machines is due for n good part to the simple form of the rack-shaped fool, which l comparatively easy to

They are not only suitable for producing involute gears, but also for sprocket whgola, spline shafts, fluted rollera atc. All types can be supplied with a robust device for cutting in- ternal gear and racku.

The MAAG Gear Grinding Machines are designed for grind- ing the tooth flanks of spur hetical, and double hellcat geors having diameters from 34" to 140". Their outstanding accuracy ly mainly due to the automatic compensating devlees adjusting the 'grinding Wheels after a ̈ Wear" of 0.00005" to 0.0001", and to the mechanism employed for the

Exports High In Electric Gear

The outstanding part played by the United Kingdom electrical Industry in meeting the overseas demand-for. power supply is re- flected in the latest returns showing that shipments of elect- rical 'i goods In the first nine months of this year totalled more than 53,000,000,

The corresponding figure for 1938 was just over £10,000,000. One firm-the General Electric Company-which has made a notable contribution to these re- ford exports, has announced that Its present annual rate of ship- ment is now running at no less than 247 per cent over 1938, The industry's offelal target for the end of 1948 is a volume 184 per cent of prewar.

General Electric Company The claims that its outstanding achievement has been made pos- sible by the work of a world- wide organisation, its home fac- torics and the reputation for quality is goods established for over half contury in every branch of the electrical field. No other firm in the world, says the G.E.C., could make this claim.

GEC: now plans to spend more than £1,000,000 on extensions to fis electrical engineering works at Birmingham and to its mechani- cal department at Erith, Kent, to meet the continued world demand for... power station generating plant. These extensions, which .will include a new turbo alter- nator works capable of manufac- turing generators of 130,000 horse- power, nearly twice the size of the largest standard unit at pre- went being made in Britain, will double its output of generators enable the Company abnost Work on now extension is. to start immediately; and it--- La „ex- dinary use in workshops, tog luka pected that they will be in pra
