- 2 - Cont'd.{John DeLooze - Company Secretary} Rm.{William Robotham - Chief Engineer}10/ML.20.11.40. that a filter through which the oil flows slowly will produce better results than one which has to allow the unrestricted passage of several gallons of oil per minute, an accurate comparison between the performance of full flow and by-pass filters of equal dimensions would be of considerable value, and possibly Mr. Worth could be induced to undertake the necessary research work to get the required information. The manufacturers endeavour is to give the customer the maximum durability with the minimum weight and cost. In pursuit of this objective therefore, it is imperative that we should have some comparative information as to the most economical and efficient means of maintaining clean oil in the power unit.
