A technique for controlling the flow of solid particles including at least a certain minimum amount of magnetizable particles in a static fashion, that is, without moving parts is disclosed herein. This technique which relies on magnetism may be utilized for providing a static on/off valve for solids, a static variable control valve for solids, and other valve related operations. The disclosed technique may also produce a distributor for a fluidized bed of magnetic particles along or in combination with non-magnetic particles, and can also be used as a positively controlled distributor-downcomer for single or staged fluidized beds.

A magnetically operated valve arrangement for turning on and off the flow of solid particles including at least a certain minimum amount of magnetizable particles, said valve arrangement comprising: (a) means defining a confined pathway through which all of said particles are adapted to flow from an upstream point when said valve arrangement is maintained in an opened operating condition; (b) fixed structural means extending into said pathway without preventing said particles from flowing therethrough when said valve arrangement is in its opened operating condition; and (c) means including said structural means cooperating with said pathway for closing the latter to the passage of upstream particles at any given time by causing downstream magnetizable particles passing through the pathway at that time to become fixedly magnetized to one another at said structural means within said pathway in sufficient quantity to completely close the latter to the flow of solids.
