Abstract:

The system was set up at this Laboratory and closely observed while under the endurance, accuracy, and shock tests. Total revolutions of the port and starboard shaft transmitters and the master indicators were recorded and compared daily. Both transmitters were rotated ahead at approximately 250 r.p.m. for a period of 500 hours. The direction of rotation of both hafts was reversed for one hour during each day of the test. A careful examination was made of the instruments to ascertain whether the material submitted was in strict accordance with the specifications in the matter of materials, design, workmanship, dimensions, markings, etc.
