  • Patent number: 11992927
    Abstract: A pneumatic chisel includes a housing having a double-acting pneumatic cylinder in which a piston including a chisel is movably arranged along a longitudinal axis. The cylinder has a work-side section and a return-side section. The return-side section includes a damping portion and a pressure-equalization opening. The work-side section includes an end-position damping member and a compressed air connection. A compressed air reservoir is connected to the return-side section of the cylinder. A chisel guide housing includes a sealing air chamber. The piston is constructed as one piece with the chisel.
    Type: Grant
    Filed: October 8, 2018
    Date of Patent: May 28, 2024

  • Patent number: 10442596
    Abstract: Reduction of contamination and the proportion of fines fractions in the packaging of rod form polysilicon is achieved by directly filling a plastic bag with polysilicon from a cleaning bowl by a rotating motion which causes polysilicon chunks to slide into the bag.

  • Patent number: 10335832
    Abstract: Granular polysilicon is fed into a screening plant, divided into two or more fractions by means of one or more screen surfaces, and thereby classified and dedusted wherein a throwing motion of the granular polysilicon in the screening plant removes adhering dust particles from the granular polysilicon, the removed dust particles are taken off from the screening plant by means of a gas flow supplied to the screening plant, and the screening plant is of gas-tight design and supply and takeoff of the gas flow are effected such that the screening plant is at a positive pressure compared to the surroundings.
