Abstract: A method is for isolation of a permeable zone in a subterranean well, wherein the well is provided with a pipe body. The method comprises lowering a perforation tool into the pipe body; forming holes in the pipe body along a longitudinal section; pumping a flushing fluid out through outlets in a flushing tool, into the pipe body and further out into an annulus; pumping a fluidized plugging material out through the flushing tool, into the pipe body and further out into the annulus; placing the fluidized plugging material along the longitudinal section so as to form a plug across the cross section of the well, whereby the plug fills the pipe body and the annulus; wherein at least one outlet in the flushing tool is angled non-perpendicularly relative to a longitudinal axis of the flushing tool, whereby a corresponding discharge jet also will be non-perpendicular to the longitudinal axis.

Abstract: A method is for the combined perforation, cleaning, and the subsequent plugging of a longitudinal section of a well. The well is provided with two pipe bodies placed substantially concentrically. The method includes lowering a perforation tool into the innermost pipe body to the longitudinal section, forming perforations in both pipe bodies along the longitudinal section with the perforation tool, cleaning the longitudinal section with a flushing tool which is attached to a lower portion of a string allowing through-flow, pumping a fluidized plugging material down the string and into the innermost pipe body at the longitudinal section, and placing the fluidized plugging material in the innermost pipe body, and thereby also into the entire cross section of the well via the perforations within the longitudinal section. A flushing tool is for cleaning the longitudinal section of the well.

Abstract: A mount for attaching a device to a firearm includes a longitudinal base adapted to carry the device to be mounted. The base has a track extending along a portion of the length thereof and a block is slidably mounted in the track. The block is biased toward the front end of the base by a spring. The block is adapted to be attached to a first fixed member at one end of a firearm barrel. The rear end of the base is adapted to be attached to a second fixed member at the other end of the firearm barrel. When properly mounted between the ends of the firearm barrel, the mount is held in place by the action of the spring, which forces the block attachment against the first fixed member and the rear attachment against the second fixed member. The rear attachment also includes spring means to prevent the mount from wobbling from side-to-side when attached to the first and second fixed members and a thumbscrew for locking the spring means to the second fixed member.
