New Lubricating
Filter Developed
A new lubricating oil filter recontly developed in Britain provides an exceptional filtering sur- face by the manner in which a special grade of porous paper is creased and folded in the outer casing.
The largest machine tool evor produced in Great Britain has recently been comploted and do- livored.
This is a boring and turning mill weighing approxi- mately 475 tons, manufactured by George Richards Co., Ltd., Manchester, who have been pre-eminent in the field of precision bor- ing machine production for the past 70 years.
The accompanying illustration gives an idon of the massive proportions of the machine and a comparison of the size of the men stand- ing at the controls in the lower left hand - corner, clearly indicates this impressive feature. The machine is known as n 35/50-foot extension type vertical borbig and turning mill. The term *extension refers to the mounting of the main uprights, which are arranged t
