  • Patent number: 6437509
    Abstract: The invention relates to an electrode for discharge lamps, comprising a pin which is at least partially surrounded by a solid body. Said solid body consists of a material with a high melting point. The cooling body is therefore easy to mount on the pin and can be solidly connected to the same so that they form a robust unit.

  • Patent number: 5088532
    Abstract: A method and mechanism for controlling the material feed of a machine for chipping wood or brush. The machine has a pair of coacting feed rolls which feed material to be chipped into a rotating chipper that is driven by an engine of variable speed. Hydraulic motors for driving each of the feed rolls are actuated when the speed of the engine is at least a selected high level appropriate for efficient chipping. If the material is of a size or composition to load the engine below a selected low level adverse to efficient chipping, the hydraulic motors are interrupted to stop feeding of the material to allow the engine to return to an efficient chipping speed. When the engine has recovered to at least the selected high level, the hydraulic motors are reactivated to again feed material into the chipper.
