Abstract
The inflatable packer element of the present invention includes an inflatable bladder means having a braided wire reinforcing element. An end of the reinforcing element is received between a tapered surface of an annular anchor means and a tapered surface of an annular wedge means. A threaded portion of the anchor means engages a threaded portion of an annular ring. The wedge means is slidably received within the annular ring and engages an abutment of the ring, so that when the threaded connection between the anchor means and the annular ring is made up the reinforcing element is clamped between the tapered surfaces. An additional clamping force is then applied by applying liquid epoxy under pressure against the wedge means to further drive it toward the anchor means and increase the clamping force on the reinforcing element. The pressure is maintained until the epoxy is hardened. The joint is then further strengthened by forcing additional liquid epoxy into the area between the reinforcing element and the tapered surface of the anchor means to bond the reinforcing element to the anchor means.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
