  • Publication number: 20160199885
    Abstract: A method is provided for removing metal honeycomb from a substrate. The method includes directing a forced pulse jet of fluid at an angle of attack of between about 70-110 degrees with respect to the substrate. The fluid strikes the substrate at the base of the honeycomb to remove the honeycomb from the substrate, whereby the substrate may be reused.

  • Patent number: 7299732
    Abstract: Honeycomb removal comprises directing a nozzle at the surface of a substrate at an angle of less than about 90° such that the water will strike the substrate at the base of the honeycomb, parallel to the direction of the ribbon which forms the honeycomb structure. Water then passes through the nozzle and through the orifice at a pressure and flow rate sufficient to remove the honeycomb and preferably the underlying braze from the substrate surface. Relative motion is created between the substrate and the nozzle such that the water stream advances to an area which honeycomb has not been removed with the stream continually being directed at the base of the honeycomb.

  • Patent number: 6648242
    Abstract: A mechanism that steers a high energy density output(s) in a shaking motion other than a rotating motion that when translated across a surface evenly affects the surface. One application can be used as an end effector. A pivot on the mechanism induces an angular motion that eliminates the tops and bottoms of the pattern produced by the shaking motion. As a waterjet stripping mechanism which may be an end effector, a nozzle or output manifold with one or more orifices or outputs is attached to a non-rotating tube eccentrically mounted within a rotating tube that shakes the nozzle or output manifold so as to direct the stream of water to the target in a skewed circular pattern.
