Text: Keely invented what he called a "resonating ring." The old straight tube resonators in his "Generator" continually had the caps blown off from them by the violent vortex action generated in them at periodic intervals by his "reversions." To avoid this annoyance, he invented these "resonating rings" which are simply resonating tubes arranged in the infinite circle. The laws of their resonation are not known, and he does not mention the particular vibrational effects which he obtainedwith them, other than that they "held the neutral focalization intact" during disintegration. In making these he used extraordinary care. The tubes were passed between triple rollers, set to give a slight bend, and were then fastened to a bed plate and a steel ball of the exact diameter of the tube was forced through it. These operations were continued until a semicircular section of this ring was formed, eighty bends and as many corrections being sometimes necessary for the complete ring, and two hours' time required for each bend. The two semicircular sections were then placed in a steel mold kept under hydraulic pressure for two or three days to correct lateral deflection or strain. They were then screwed rigidly to a face plate, soldered and to correct differentiation in molecular groupings, were placed in a hot sand bath that required seventy two hours to cool. The sympathetic negative transmitter was then attached and vibratory receptiveness was inducted in the ring until it gave, when struck, a pure unmixed chord, as shown by the indicator attached to the ring. The ring was then centered on a steel shaft and revolved at 2000 revolutions per minute, surrounded by the "triple circuit ring." If the indicator in the "circuit ring" varied 5 degrees out of a possible 8,000, the ring had to be corrected until it varied by no more than 3 degrees, which could be considered perfect enough, since the circular tubular resonator could then hold the neutral focalization intact during the graduation of the full ninths, for sympathetic association to produce polar negative attraction. His operation of revolving the ring 2,000 times per minute and noting the variations in its harmonic state, would seem to indicate that he intended it as the constituent of the internal volume of his disintegratory sphere, or if not, that he used it in a sphere-interrupter. It is elsewhere mentioned that this device "held the focal chord intact" which would go to show that its mechanical action was the continuation through the mechanical energy imparted to it, of preserving the harmony or chord of mass in the sphere of which it was mechanically a part.
