We own the rights to U.S. Patent 5,442,846 which is titled "Procedure and Apparatus for Cold Joining of Metallic Pipes." We have conducted research and development operations regarding our patented pipeline connection technology. We have developing equipment designed to join large diameter pipe utilizing magnetic pulse methods, a cold form method joining a metal sleeve around the ends of two abutting pipes. A hinged magnetic work coil developed by us is clamped around the sleeve joining two pipes to produce a ringed shaped crimping force forcing a uniform joint with uniform stress distributions. The pipes may have annular grooved ends, grooved to approximately 1/3 of its depth, to be gripped by the grooves of the sleeve. A pressure sensitive adhesive may be applied to the pipe ends to improve the performance and seal of the splice. When the magnetic pulse is applied by the equipment, it instantly crushes the sleeve onto the pipe and into the shallow grooves milled into the pipe ends, which improves its pullout resistance.
This pipeline connection technology is particularly useful for joining oil and gas pipelines, oil and gas well casings, and other large pipe connections such as those at refineries, chemical plants and other industrial operations. The cold magnetic impulse method creates a uniform joint connection between pipes. The magnetic impulse method also has the advantage that it can be performed in the field in any weather condition.
Our pipeline connection technology is based upon the principle that whenever a rapidly changing magnetic flux cuts across a conductive material, such as the grooved sleeve to be used in our design, a current is induced in the material. The current is proportional to the initial intensity and time rate of change of the magnetic flux. The induced current creates an associated magnetic field of such polarity as to oppose the magnetic field producing the current, creating very significant forces of repulsion. This effect is commonly called "Lenz's Law of Repulsion". This repulsion force of our work coil pinches the conductive sleeve around the pipes.
To commercialize the pipeline connection technology, we must complete the design of a modular clamp, a field fastening system, field power supply systems for onshore and offshore applications and a control unit. We have solicited and received a proposal to design, engineer and fabricate a prototype power supply system from IAP Research, Inc. ("IAP"), a product development engineering services firm that specializes in electromagnetic metal forming and innovative electrical and mechanical engineering solutions. The budget estimate for the IAP project is approximately $500,000.

Our pipeline connection technology will require additional development, design and engineering, fabrication of machinery, testing, and evaluation before a field unit capable of joining large diameter pipe can be manufactured and delivered to potential customers. We have not made the decision to discontinue our research and development activities regarding patented alloy sensor technology; however, during the year ended January 31, 2005, no research and development activities regarding patented alloy sensor technology were conducted, due to lack of funding and Management's decision to concentrate primarily on developing our battery technology.
That was purchased by Power Technology, from Alvin Snaper, about seven years ago. There never was any argument about the ownership of the Pipe-Link Patent, or the Sensor Patent, which was also purchased from Alvin Snaper.
