  • Publication number: 20240075607
    Abstract: A handheld work apparatus includes a motor, a transmission shaft, a tool, a guide tube, a housing, and a first anti-vibration element. The motor via the transmission shaft drives the tool. The transmission shaft is received in the guide tube. The motor is disposed in the housing. The tool is disposed on a front longitudinal end of the guide tube. The housing is disposed on the rear longitudinal end of the guide tube. The housing at least partially encompasses the guide tube, wherein the guide tube projects from the housing. The first anti-vibration element is disposed such that it acts in a vibration-decoupling manner between the housing and the guide tube. The first anti-vibration element is disposed on that side of the motor facing the tool. The handheld work apparatus includes a second anti-vibration element connecting the motor to the housing in an at least indirectly vibration-decoupled manner.

  • Patent number: 7279839
    Abstract: A short arc high-pressure discharge lamp (1) for dc operation, includes a discharge vessel (2) that has two necks (4) diametrically opposite each other, in which an anode (26) and a cathode (7) made of tungsten are melted in a gastight manner, and which has a filling made of at least one noble gas and possibly mercury. According to the invention, at least the material of the cathode tip (11) contains lanthanum oxide La2O3 and at least another oxide from the group consisting of hafnium oxide HfO2 and zirconium oxide ZrO2 in addition to the abovementioned tungsten.

  • Publication number: 20040169476
    Abstract: The invention relates to a mercury short-arched-high pressure discharge lamp (1) which operates with direct-current, comprising a discharge vessel (2) having two necks (4) arranged in a diametrical manner opposite each other, wherein an anode (26) and a cathode (7), made respectively from tungsten, are melted in a gas-tight manner and said vessel is filled with mercury and at least one inert gas. According to the invention, the material of the cathode tip (11) contains, in addition to the tungsten, lanthanum oxide La2O3 and the mercury content of the filling in the discharging vessel volume is at least 1 mg/cm3 and at the most 6 mg/cm3.
