Patent number: 9314910Abstract: Dynamical flange clamp for strengthening flange couplings or taking over the bolt forces in a loaded flange coupling, where opposite clamps (1, 2) are preloaded towards each other, contraholders (3) are fitted on one of the clamps (2), functioning as back stop to absorb the preload. When installed on a flange connection the gasket stress is kept virtually constant during the transfer of forces between the flange coupling bolts and the flange clamp. This is done without any further adjustments to the dynamical flange clamp. The dynamic flange clamp is particularly useful during bolt changes in a Hot Bolting operation.Type: GrantFiled: March 25, 2010Date of Patent: April 19, 2016Inventor: Per-Christian Irgens

Patent number: 9309927Abstract: A rotational driveshaft coupler that converts a rotating shaft motion into two orthogonal oscillations and at the opposite side of this coupler, a third oscillator converts the oscillations back to a rotational motion. At least one slip free seal can be constructed from the coupler to its housing to separate the space occupied by the output shaft from the space occupied by the input shaft. Each of the three oscillating motions can be guided by bearings, gears and tracks to reduce frictions and heat generation. Permanent magnet pairs are used to prevent bifurcation and force the output shaft to follow the rotation direction of the input shaft. Unlike in magnetic coupling, the torque transmission here is direct.Type: GrantFiled: September 17, 2011Date of Patent: April 12, 2016Inventor: Chung Chang

Patent number: 9295224Abstract: A portable barrier wall used for preventing the passage of people, vehicles, projectiles, blast debris, liquids, wind or waves through the wall. The wall is constructed of one or more x-shaped freestanding support structures arranged in parallel orientation to form a frame for holding retaining members that attach to the support structures. The retaining members form U-shaped containment structures within each segment of the wall. Fill material is added to the containment structures which are then sealed. Connecting means attach the two support structures together to prevent movement. Wall used to contain liquids may additionally include a liquid impervious layer that is placed external to the retaining member on the side of the barrier wall that will be in contact with liquid and the layer is anchored under the feet of one of the support structures. The wall may additionally hold absorptive or adsorptive materials to contain spills and contaminants.Type: GrantFiled: September 25, 2013Date of Patent: March 29, 2016Assignee: ArdenX LLCInventors: Dennis Arden, H.
