Patents by Inventor Murray Jamieson Mcintosh

Murray Jamieson Mcintosh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10295007
    Abstract: A load absorber dampens relative movement between subsea bodies. The load absorber is cooperable with an actuating member such as a male piston element or a female cup on an opposed subsea body. The load absorber comprises a hollow structure defining an internal flow path for water. A flow restrictor acting on the flow path restricts a distal flow of water along the flow path from a proximal opening, caused by convergence between the actuating member and the load absorber. The flow restrictor comprises a shuttle element to restrict the flow path that is mounted to the structure for automatic movement from a first state to a second state in response to an increase in water pressure at the proximal opening. In the first state, the shuttle element effects greater restriction of the flow path than in the second state.

  • Patent number: 8939702
    Abstract: Apparatus and method for handling a fluid-tight flange coupling between a first and a second conduit component while maintaining the fluid integrity of the coupling. The apparatus includes a gripping mechanism configured to straddle the flange coupling and grip both of the first and second conduit components. The gripping mechanism is mounted on a lifting frame able to bear the loadings upon the gripped components during a moving operation. The apparatus includes a base frame with a gripping mechanism to receive the flange coupling. The coupled components are gripped on each side of the flange coupling to maintain the fluid integrity of the flange coupling.
