Abstract
In therapeutic apparatus producing ultraviolet and infra-red rays simultaneously, an electric discharge tube generating the former rays is connected in series with a glowing wire or other device generating the latter rays so that the efficiency, as compared with prior devices in which the wire and tube are in parallel, is improved by using the wire as part or the whole of the ballast resistance of the tube. The tube may have activated electrodes and may operate at 5 amps. and less than 100 volts. The tube and wire may be in a common reflector focusing the rays from both on the same spot or the wire may be in a separate receptacle or reflector. If the wire generates too much infra-red radiation when used as the whole ballast, this radiation may be weakened by a diaphragm or the wire may be placed at a greater distance from the body than the discharge tube or an ordinary ballast resistance may be used in series with the wire and tube. The infra-red radiator may be a spiral or double spiral wire or band glowing in air or gas such as hydrogen or may be an ordinary lamp emitting visible rays as well.
