Patent number: 10625328Abstract: An improved electro-hydraulic clinching system involves generating, through a high potential electric shock, a forceful wave in a fluid such as water, and applying the force of the wave to a sheet of metal. The force of the wave results in deforming the sheet and making the sheet material move through a hole in a second sheet adjacent to the first sheet, thus joining the two sheets. In an alternative implementation, in which neither sheet includes an opening, the force of the wave moves both sheets simultaneously, thereby causing them to join together at the point of impact.Type: GrantFiled: March 12, 2018Date of Patent: April 21, 2020Inventors: Vahid Babalo, Mahdi Soltanpour, Ali Fazli, Rasoul Jelokhani Niaraki

Publication number: 20020029449Abstract: The invention relates to a process for the manufacture of reinforced-reinforced pressure vessels and the product produced therefrom. A ductile metal vessel liner, being formed with at least one nozzle, is wrapped with a first composite layer of resin-impregnated fibers. Pressure is applied to the vessel sufficient to yield the liner but is insufficient to cause deformation of the nozzle. The liner retains a residual compressive stress critical for withstanding cyclical service pressures. A second composite layer is applied over the first layer to increase the strength of the vessel sufficient to maintain the vessel's integrity at very high cyclical service pressures (such as about 0-10,000 psig). The vessel is then pressure tested at 1.5 times the intended service pressure to ensure vessel integrity.Type: ApplicationFiled: September 10, 2001Publication date: March 14, 2002Inventor: Heinz Portmann
