resonating plates

"May 20th.- Yesterday was a day of trials and disappointments. It seemed as if nothing would work right. After labouring six hours to set my safety process, the first operation of the Liberator tore the caps all to pieces. I replaced them by a set of duplicates and set the Liberator down to the low octaves, when everything worked to a charm. Night was approaching and I left the workshop to get something to eat, returning about eight o'clock to re-conduct experiments, in order to discover if possible the cause of the sudden and most unexpected intensification. I followed up with great care the progressive lines until I reached the tenth octave and then liberated a score of times, yet no variation on liberator. Next, I made an attachment to my safety arrangement, and also to my strongest resonator to experiment on vibratory rotation with my shell; when, within two minutes, it attained a frightful velocity: then I suddenly retracted to the negative, bringing the velocity down from about 1500 per minute to 150. The operation was magnificent, lasting sixty-four minutes, when a second intensification took place, demolishing two safety-shells and one vibratory indicator. I was perfectly dumbfounded, and unable to account for such a phenomenon. It was then near midnight, but I had made up my mind not to discontinue until I had solved the mystery. After an hour's reflection, I set up a new position on the resonating wave plates in the forty resonating circuit on the base of liberator; and got a result which for purity of uniformity surpassed all experiments that I have ever made. I believe I have now struck the root of this difficulty, and that I shall be able to master it; and obtain continuity of action with perfect rotation." [The Nature of Keelys Problems]
