Abstract: An energy management system includes one or more electric power generators located at or near a consumer's premises, to provide power which is dedicated to the needs of that consumer. The power provided by the on-site generators complements that which is delivered via a centralized power grid network. In the event that the power grid is disabled, or is otherwise unable to provide adequate power to the consumer, the on-site generators are switched to provide power to critical equipment. In one embodiment, a computer-driven control facility selectively actuates the on-site generator to intelligently arbitrage between the locally generated power and that which is provided via the grid network, based on a variety of factors. The instantaneous cost of power supplied via the grid network is compared against stored costs of operating the on-site generators, such as the price of fuel required to run the generators, maintenance expenses, other types of service and installation expenses, and finance charges.

Abstract: A process for making a ferrite spherical particulate toner carrier core from a raw fly ash comprising recovering the magnetic particles from the non-magnetic particles of the raw fly ash; selecting a desired size for the particles of the raw fly ash and screening the fly ash to obtain the desired sized particles; and purifying the resultant raw fly ash to obtain a ferrite composition having a particle size from 20-300 microns, in which the particles are essentially spherical, having an apparent density of at least 1.8 g/cm.sup.3, a saturation magnetization of 43-70 emu/g, a remanence of 5 emu/g or less, a Hall Flow of 20 sec. or greater/50 g.

Abstract: A ferrite toner carrier core composition derived from flyash comprising a mixture of spherical particulates of the general formula ##EQU1## wherein iron is the principal metallic element and i,j,k denote the number of atoms of monovalent, divalent and trivalent atoms present in one mole of the compound, andM.sub.x denotes monovalent atoms from Group IA of the Periodic Table, the alkali metals, usually sodium or potassium, alone or together.M.sub.y denotes divalent atoms from Group IIA of the Periodic Table, the alkali earth metals, usually magnesium or calcium, alone or together.M.sub.z denotes trivalent atoms from Group IVB, usually titanium, Group IVA, usually silicon and Group IIIA, usually aluminum. All permutations and combinations may be present.
