HS{Lord Ernest Hives - Chair}/Bl.4/MA.21. 3. 32. *TECALEMIT* OIL FILTER. Motorine "C" oil was supplied to the inlet of the filter by a gear pump controlled by a variable speed electric motor. The pressure in the delivery pipe, and incidentally the filter was controlled by a tap in the delivery pipe, the pressures in the inlet and outlet pipes being registered by dial gauges. The pressure difference in the two pipes were measured at temperatures between 20oC and 80oC at a constant delivery of 250 galls/hr. Free Delivery. 25lb/sq.in. outlet press Temp oC.
