    Abstract: A method of producing U.V. radiation by effecting an electrical discharge such that at least a part of the discharge path is submerged in water. An apparatus for performing the above method comprises two electrodes spaced apart to form a discharge region, a discharge chamber containing the discharge region, means arranged to apply a high voltage across the electrodes, and means arranged to supply water to the discharge region such that at least a part of the electrical discharge is submerged in the water, at least a portion of the discharge chamber being transparent to U.V. radiation. Also, a method of treating a material comprising producing U.V. radiation as described above in a discharge chamber at least a portion of which is U.V. transparent, passing the material through a treatment chamber adjacent the transparent portion of the discharge chamber; and an apparatus for performing the method of treating a material. In some described embodiments the position of an electrode is adjusted in dependence upon the electrical characteristics of the discharge such as to maintain predetermined conditions. In one embodiment an electrode is mounted in the bottom of the discharge chamber which forms the other electrode; water covers the electrode and has a controlled circulatory motion such as to control the height of water over the electrode and thus the submerged discharge path. In another embodiment one of the electrodes is formed by a layer of mercury; an initiating discharge between a third electrode and the mercury or the other electrode to establish a degree of ionisation of the mercury in the vicinity of the discharge region. The main discharge excites the mercury vapour resulting in radiation at 254 nm.

    Abstract: A high intensity sodium vapor arc lamp utilizing a slender tubular envelope of alumina ceramic having self-heating electrodes mounted at opposite ends and containing an excess pool of liquid sodium-mercury amalgam at the cold spot in the lower end. The electrode at the lower end includes a resistive heater portion and lamp current flowing therethrough provides supplementary heat to the amalgam pool varying according to lamp current. In conjunction with the inductive ballast characteristic this stabilizes the cold spot temperature and amalgam vapor pressure, and counters the tendency to arc voltage rise with life. It also reduces the sensitivity of the lamp to radiant energy reflected back from the fixture.

    Abstract: 957,921. Electric discharge lamps. GENERAL ELECTRIC CO. Nov. 24, 1961 [Dec. 27, 1960], No. 42095/61. Heading H1D. [Also in Division F4] An illuminating device comprises an enclosure having a transparent wall and means for holding in the enclosure a lamp containing a vaporizable substance, the temperature of the lamp being controlled by a heat-conducting device which extends from the interior of the lamp to the exterior, and is so arranged that its inner end contacts for heat conduction a restricted area of the lamp and its projection extending outside of the enclosure serves for heat dissipation. In one form, a part 5 of a lamp 3 is contacted by a tubular container 4 which extends upwardly to the outside of the enclosure 1 and which contains a vaporizable liquid and a non-condensable gas, and in operation, the liquid is co-operated, the vapour condensed in a copper condenser 9 and the liquid returned to the lower part of the device. Alternatively, two hollow tubes may be used, one inside the other, and the vapour forced up the inside of the smaller tube to be condensed on a heat-dissipating surface preferably cooled with cooling fins, and the condensed liquid returned between the two tubes. In either case, the outside tube may be lagged with material 20, and a heat-conducting grease used between the lamp and the heat-conducting device. Specifications 472,307 and 821,321 are referred to.
