  • Optimizing method for regulating the operating state of a guided machine tool comprising a rotating percussion tool during a boring process
    Patent number: 6854529
    Abstract: Disclosed is an optimizing method for regulating the operating state of a guided machine tool having a tool rotating at a certain speed and subjected to a percussion frequency during a boring action, in which the tool, subjected in addition to a force, is driven into an object of a given material.

  • Method for retrieving predetermined locations in sewer and pipeline systems
    Patent number: 6853200
    Abstract: A method for retrieving predetermined locations in sewer and pipeline systems after application or deposition of a layer of material. A carrier vehicle having a microwave sensor emits microwave signals and receives backscattered microwave signals. A first run is conducted inside the sewer or pipeline system before application or deposition of the layer of material. A first temporal signal profile of the backscattered microwave signals is recorded and the sought locations are marked in the first signal profile. After the application or deposition of the layer of material, a second run is conducted. A second temporal signal profile of the backscattered signals is recorded. The current position of the vehicle in the sewer or pipeline system relative to the sought locations is determined by comparison with the first signal profile.

  • Friction driven flexible, endless conveyor belt
    Patent number: 6564930
    Abstract: An endless conveyor has a driven drum that rotates about its axis. A flexible band forms a helix by being wrapped around the drum. A fixed helical support supports the outer edge of the band. A secondary conveyor moves an endless series of stacking blocks. The stacking blocks are in frictional engagement with the drum to transfer driving forces from the drum to the blocks. The stacking blocks also keep the turns of the flexible band spaced apart by a distance equal to the height of the blocks. The secondary conveyor includes guides at both the top and bottom of the drum to guide the stacking blocks into and out of engagement with the inner edge of the flexible band. The stacking blocks are in slip-free and backlash free engagement with the inner edge of the flexible band, and the frictional engagement between the stacking blocks and the drum permits the stacking blocks to be displaced both axially and circumferentially on the surface of the drum.
