Abstract: Fly ash is agglomerated into pellets in order to render it environmentally harmless and suitable for dumping. The fly ash is mixed with water in an unclassified condition and formed into green pellets which are heated in a two-stage heating process. In the first heating stage carbon in the pellets is rapidly gasified while iron present is not reduced below Fe 3 0s. In the second heating stage, the pellets are rapidly sintered. The whole heating process is less than 60 minutes and to permit this rapid heating, the pellets must be of sufficient porosity to withstand the rapid gasification of the carbon and the rapid sintering without breaking up.

Abstract: Disclosed is a system that provides protection for a high voltage transmission line. The system employs improved polarizing and operating signals for both a phase selector relay and a distance measuring relay. The improved polarizing and operating signals provide an accurate out-of-phase relationship during the presence of normal conditions existing on a high voltage transmission line and an in-phase relationship during the presence of fault or abnormal conditions existing on the high voltage transmission line. The accurate phase relationships are utilized by phase comparator circuits of each of the phase selector and distance measuring relays to obtain desired operating characteristics for each relay. In another embodiment, the desired operating characteristics of the phase selector and distance measuring relays are obtained by an amplitude comparator circuit. in a still further embodiment, the distance measuring relay is operated under the control of the phase selector relay so as to provide the proper desired phase selection and protection of the high voltage transmission line.
