  • Injection molded ceramic metal halide arc tube having non-tapered end and method of forming same
    Patent number: 7382097
    Abstract: An arc tube for a ceramic metal halide lamp includes a hollow first body member (40) that is tapered along a majority of its length to aid in removing the molded component from a pin during assembly. An open end (46) of the first body member has a constant diameter (60) allowing it to be joined to a constant diameter portion (72) of the second body member or end cap (70). The mating constant diameter portions ensure that the hollow first body member can be monolithically joined with the end cap with a reduced level of seal voids.

  • ULTRAVIOLET EMITTING SCINTILLATORS FOR OIL DETECTION
    Publication number: 20060027742
    Abstract: An aspect of the present invention is directed to a system for use in oil well drilling applications. The system includes a scintillator material having a cubic garnet host and praseodymium distributed within the host. The scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation. A radiation detector optically coupled to the scintillator detects the emitted ultraviolet radiation. Another aspect of the invention is a method for detecting oil. A radiation detector is optically coupled to a scintillator material having a cubic garnet host and praseodymium distributed within the host, wherein the praseodymium acts as an activator, and wherein the scintillator material emits ultraviolet radiation in response to stimulating gamma ray radiation.
