    Abstract: The spectral energy characteristic of a discharge lamp is controlled by changing the density of the fill substance. The spectral characteristic can be shifted while substantially maintaining its shape by changing the density of the fill. A sulfur or selenium containing discharge lamp which is operated at a pressure of at least about 1 atmosphere contains a low ionization potential substance in the fill. Characteristics which are improved are one or more of spatial color uniformity, extinguishing characteristics, and bulb starting reliability. Particular substances which are added to the fill are alkalai metal containing substances, III B metal containing substances, and alkaline earth metal containing substances. When light is reflected back into the bulb, the light which is re-emitted is stronger in the higher wavelengths.

    Abstract: Ignition of an electrodeless lamp, energized by microwave or radio frequency energy, is achieved by disposing an additive material in the lamp envelope along with the primary fill material. In a first embodiment, the additive is at least partially electrically conductive at room temperatures but non-conductive or a vapor at lamp operating temperatures. The preferred additives for this embodiment are mercury sulfide and mercury selenide. In a second embodiment, the additive is a material, such as piezoelectric crystals, that produces sparks in the envelope when the crystals collide with each other, or with other materials, in response to agitation of the envelope. The additive may alternatively build up electrostatic charge by rubbing along the interior surface of the lamp envelope when the envelope is agitated, the charge build up being sufficient to ignite the primary fill material.

    Abstract: A valve stem gas leak sensor or detector configured to surround a possibly leaking petrochemical or like flow line valve stem and provide for external monitoring equipment an electrical resistance related to the amount of hydrocarbon gas leakage occurring around the valve stem. Such a gas leak detector, termable a ring sensor, is configured as a stem surrounding enclosure, with interconnecting segments for ease of installation around and removability from a valve stem, with one or both of each such segments having an interiorly arranged layer of gas sensor particulate material characterized by change in electrical resistance in the presence of a changing concentration of hydrocarbon gas leakage around a valve stem, and with interengaging connector/conductor pins holding the segments together around the valve stem and across which the electrical resistance of one or both gas sensor material layers can be measured with the ring sensor in place on the valve stem.
