  • Apparatus and method for carrying out in a controlled atmosphere material fatigue tests in a high cycle regime with a controlled strain ratio
    Patent number: 9383303
    Abstract: An apparatus for carrying out high cycle fatigue tests of a specimen under high pressure, including: a pressure vessel; a load train including a first horn and a second horn between which a specimen is to be arranged, wherein the load train is arranged within an internal chamber of the pressure vessel; and a converter configured to apply ultrasonic waves into the load train by exciting the first horn to apply a dynamic stress to the specimen. A base part of the second horn is movably seated in the pressure vessel such that two separated chambers are formed within the pressure vessel with the first chamber for the specimen, wherein both chambers can be fed with gas and charged with different gas pressures in order to apply a static stress to the specimen.

  • Mercury-free discharge lamp having a translucent discharge vessel
    Patent number: 8736165
    Abstract: A mercury-free discharge lamp with an electrical power consumption of less than 35 Watts may include a translucent discharge vessel which has a discharge space into which electrodes protrude for generating a gas discharge, wherein metal halides and ignition gas are contained in the discharge space, wherein the metal halides are present in a quantity in the range from 5 milligrams to 15 milligrams per 1 milliliter of discharge space volume in the discharge space.
