New Cylinder Metal

The use of a new metal for the cylinders of cars is announced by an English motor company. For five years the firm’s research department has been experimenting with alloys for cylinders with a view to prohibiting

the excessive wear which has become recognised as an almost inevitable in the modern high-speed engine. The moment the metallurgists were satisfied that they had solved the problem, engines were constructed from the new metals and were subjected to continuous night and day tests under ordinary road conditions. When three cars had completed 30,000 miles each, the equivalent of three or four years’ average running, the engines wero dismantled. The result was that praetically no wear could bo detected by

instruments capable of measuring to less than a tenth part of one-thousandth of an inch. In the ordinary way, after this mileage, an engine would need its cylinders reground and “oversize” pistons would bo necessary. The new material, which is a-chrome alloy, has now been adopted for general production. Its employment reduces oil consumption to a minimum and prohibits the development of mechanical noises. In addition distortion is negligible, so that valve-grind-ing is seldom, necessary.

Nine years ago a Turk named Jemil was accused at Istanbul of stealing £4. The trial has dragged on until this year, and Jemil has recently been, ecquitted. Halt! Who goes there? the sentry cried, And came down to the “ready” The stranger sniffed and coughed a bit Exclaiming “Here, go steady!” You want tho password 1 suppose

“Tishoo!” “Tishoo!” “McGruer!” Pass friend! All’s well the sentry said Take Wood’s Great Peppermint Cure.
