The ionizing electrode extends beyond theends of the pipes and is provided with an enlargement adja-cent each pipe end, so that its surface field intensity is re-duced at those points. The gas is introduced into the headerand passes upward through the pipes, wherein the suspendedparticles are separated from the gas and driven against thesurfaces of the pipes.

Electric Ore FurnacePatent No. 1,252,635, issued to John A. Ward of Spokane,Washington, discloses a novel form of electric ore furnaceand a novel method of controlling the flow of current throughthe heating element. The furnace is heated by the flow ofcurrent through a heating coil surrounding the furnace and the current through the heating coil is controlled by a pair ofadjustable arc forming electrodes in the circuit which are ar-ranged exterior to the heater itself so that they have inde-. pendent heat radiating properties. A plurality of electrodesextend through the furnace wall into contact with the orecontained in the furnace for the purpose of producing arcswithin the furnace, and a switch is arranged to divert thecurrent from the heating coil to the electrodes, the switch be-ing constructed so that it closes the circuit through the elec-trodes and the body of ore before it opens the circuit throughthe heating coil. Voltage RegulatorPatent No. 1,252,451, issued to Charles H. Kicklighter ofPasadena, California, and assigned to Westinghouse Electricand Manufacturing Company, discloses an improved form ofvoltage regulator for a dynamo-electric machine. The regu-lator consists of co-operating contact members, an actuating
