Std Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) condenser N° 524 3. U.S.A Bosch condenser. (Marked 774) Group B 4. Exptl condenser N° 613 baked at a higher temperature. 5. Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) condenser N° 32 below std in capacity. 6. Std Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) condenser N° 547. As it was necessary that the temperature should be raised and lowered slowly, and therefore impossible to complete a cycle of temperature in one day, the temperature had, at times, to be raised to the point at which it was left the previous day. These intermediate heatings up were not fully taken account of in testing the first group, so that only the two main curves were obtained. ie with temperature rising and falling. In the second group, however, when thus raising the temperature, readings were Cont'd. {John DeLooze - Company Secretary} Signed This Sheet must be filed on completion of the work. | ||
