Fev. 17 1932. H. E. Edgerton. We demonstrated the stroboscope to the visiting committee on monday afternoon. first I explained the [struck: uses] properties of the device. Then I showed some movies of the motion of a claw mechanism. The 480 f.p.s. camera and lamps were next shown. The 20 ft. piece of film showing the falling milk drops was finally shown. Then they went out to the sub-station and saw the 187 kva [?] [struck, illegible] synchronous motor oscillate. On tuesday, Feb 16, I worked most of the day with Grey and Siebert for their laboratory work in connection with Lyous course. They are to take oscillograms of the oscillations of a synchronous motor 804 A following a sudden change of shaft load. Mr. Holmes [struck: of] who I met at the Raytheon Inc. was over to find out about thyration [?] circuits for dimming. I showed him a phase shifting circuit of this type. [diagram] Mr. Sperry [?] of NoYo was here today and I showed him the stroboscope and the continuously moving film cameras. Draper brought him over.
