PLATE IV COMPRESSION MACHINE DETAIL. —~ -y- DESGRIPTIOU OF TESTS. alGrH SPEED ENGINE IHDIGATOR-At first an investigation was madeinto the possibility of using some form of carbon to indicate thepressure in a high speed gas engine cylinder. For this purpose,the apparatus described on page four and shown on Plate two was con-structed. The pressure from the engine cylinder was transmittedthrough the indicator piston to the carbon in the rubber tube. Thecarbon discs were connected in series with a storage battery and anoscillograph, as previously described. As the engine rotated, thepressure varied the resistance of the carbon in the tube. This theifcaused a variation of the current which was recorded on the oscillo-graph. As soon as it was found that any apparatus of this sortwould necessi tate complicated calibration tables, the project wasgiven up and the investigation discontinued. STATIC PEESrjRS TESTS.-The testing machine described on Page 3and shown on Page 6 was then constructed
