    Abstract: An apparatus for treating a workpiece with a granular media includes a hopper for storing media and discharging the media into a flow path. A source of compressed air mixes with the media, which is forced through a nozzle for directing media onto the workpiece. A flow sensor includes a beam extending into the flow path and is responsive to flow of media in the flow path to increase and decrease deflection of the beam in response to increasing or decreasing flow of media through said flow path. A proximity sensing device measures deflection of the beam and generates an electrical signal which varies in response to deflection of the beam. The flow path is defined by a conduit having a branch in which the beam is mounted. One end of the beam is mounted on a base in the branch. The base is mounted on a cap closing an open end of the branch, permitting the beam to be easily removed and changed when necessary.

  • Patent number: 8251773
    Abstract: A control system for a high pressure cutting arrangement is disclosed. The cutting arrangement comprises a liquid stream and a slurry stream, the slurry comprising abrasive particles suspended in a fluid. The liquid stream and the slurry stream are both supplied under pressure of about 300 MPa to a cutting tool, with at least a portion of the supplied pressure being converted to kinetic energy in the cutting tool to produce a combined liquid and abrasive stream at high velocity. The cutting tool includes a combining chamber into which both the liquid and slurry streams are introduced, the pressure in an entry region of the combining chamber being determined by the pressure of the liquid stream. The control system acts to actuate or prevent flow of slurry in the slurry stream by activation or de-activation of an energizing means up-stream of the chamber. Pressure in the slurry stream is substantially equal to the pressure in the entry region of the combining chamber whether or not slurry is flowing.

    Abstract: Methods, systems, and techniques for automatically determining jet orientation parameters to correct for potential deviations in three dimensional part cutting are provided. Example embodiments provide an Adaptive Vector Control System (AVCS), which automatically determines speeds and orientation parameters of a cutting jet to attempt to insure that a part will be cut within prescribed tolerances where possible. In one embodiment, the AVCS determines the tilt and swivel of a cutting head by mathematical predictive models that examine the cutting front for each of “m” hypothetical layers in a desired part, to better predict whether the part will be within tolerances, and to determine what corrective angles are needed to correct for deviations due to drag, radial deflection, and/or taper.
