Abstract:

A method of treating fly ash which has a moisture content and which also has a high carbon particle content includes the steps of heating the fly ash to a temperature sufficient to break the bond between the fly ash and the carbon particles caused by the moisture content, applying the heated fly ash in a relatively thin layer to the surface of a belt-type conveyor and subjecting the layer of heated fly ash to the effects of an electrostatic charging zone while repeatedly mechanically rearranging the orientation of the fly ash particles in the zone for causing the carbon particles to take a charge and become attracted to an electrode so that the same may be separated from the layer. Apparatus for separating carbon particles from fly ash includes a generally horizontal conveyor, and a hopper which applies fly ash to be treated in a layer on the surface of a conductive belt. The belt carries the fly ash layer through an elongated electrostatic charging zone, and beaters beneath the belt impart a vibration to the belt for causing the fly ash layer to be in a state of agitation.

Abstract:

A carrier for a sheet of photographic paper or the like. The carrier including a plate smooth on one side for receiving a piece of wet paper which will adhere thereto through surface tension of the liquid, a lip at the lower edge of the plate to secure the leading edge of the paper as the carrier is immersed into a liquid bath, guides on each side of the plate both to align a sheet of paper and to space a plurality of carriers appropriately when stacked, and an irregular surface on the back of the plate to prevent paper from adhering thereto when wet.
