  • Patent number: 8196481
    Abstract: A method and apparatus for measuring the amount of fuel aboard a spacecraft under weightless conditions utilize at least one orifice, at least one flow latch valve for the selection of an orifice to be used, and at least one control valve for releasing a stream of a pressurizing gas from at least one high-pressure tank in order to restore pressure in a fuel tank following a pressure reduction due to withdrawal of fuel. The amount of fuel remaining in the fuel tank is determined based on the time required to restore fuel tank pressure by a flow of gas from the high pressure tank to the fuel tank, via the orifice.

  • Patent number: 7784875
    Abstract: A chisel holder system including a base part and a chisel holder. The base part includes a socket wherein the chisel holder with a plug-in insert is introduced. The chisel holder has a bearing surface supported on a supporting surface of the base plate, and the base part has a shoulder connected to the supporting surface. A replacement chamber is formed between the shoulder and a facing end surface of the chisel holder. According to this invention, the supporting surface is placed in the transition region in relation to the shoulder by at least one recess of the shoulder so that the flat-shaped connection between the supporting surface and the shoulder, in the region of the recess, is interrupted in order to optimize the resistance to wear and tear of the base part.
