Definitions

  • a pressure greater than atmosphere will result under disc 50 and by proper selection of the area of this disc, an upward force supporting the apparatus can be generated. Further, the flexible character of barrier 54 permits operation of the embodiment shown in FIG. 3 over a rough or non-flat surface.
  • liquid medium surrounding the fluid is an annular stream of fluid flowing alongside and at a lower velocity than the fluid jet.
  • a method of drilling a relatively solid substance which comprises forming a high-pressure and velocity water jet, restricting the flow of the water jet to increase its velocity and decrease the pressure below the vapor pressure-of the water to form water vapor cavities therein, whereby the jet will collapse at a predetermined distance from the point of restriction; surrounding the water jet with water of lower velocity than the water jet; and impinging the jet against the solid submirth STATES PATENT @EHQE QERTEEHQATE GEE Patent No. 3, 713, 699 Dated January 30, 1973 1nventor(s) Virgil E.
