8.WO/1993/008335ARTIFICIAL REEF

WO - 29.04.1993

Clasificación Internacional E02B 3/04 Nº de solicitud PCT/US1991/007923 Solicitante VAN DOREN, David, A. Inventor/a VAN DOREN, David, A.

An artificial reef is designed for replacing and protecting naturally occurring reef structures. The artificial reef comprises multiple vertically stacked concrete panels (1) separated by spacing blocks (2, 3). The panels and spacing blocks are fixed together by reinforcement rods (7) which are held in place by epoxy grout (14). The concrete panels of the reef have a flat upper surface and an undersurface of a waffled configuration and are stacked in a manner to permit substantially all of the surface area to be exposed to the estuarine environment. The waffled configuration provides a complex shape to the reef and encourages both calm and turbulent water flow within the reef so as to avoid areas of water stagnation. The modular nature of the panels permits wide flexibility in size and shape of the reef. The use of concrete provides an inert, non-corroding composition of the reef and permits on-shore construction of the reef. Lifting rings (4) embedded in the top surface of the artificial reef permit deployment by a crane.

WO - 09.05.1997

Clasificación Internacional F16K 17/04 Nº de solicitud PCT/US1996/007008 Solicitante DRESSER INDUSTRIES Inventor/a DANZY, Roger, Dale

A pressure relief valve has a body (12) including a chamber (12e) having an inlet port (12g) and an outlet (12k), the inlet port (12g) providing fluid communication between the chamber (12e) and the passageway. A guide (14) is removably secured to the body (12) and defines a bore (14e) extending into the chamber (12e) and an open-ended portion extending away from the chamber (12e). A spindle (24) is slidably disposed in the bore (14e) between a first position in which the port is open and a second position in which the disc (24b) exposed to the fluid in the passageway is recessed from the internal wall a distance no greater than one half the diameter of the passageway. A spring (32) and adjusting screw (38) are disposed in the open-ended portion of the guide and bears on the spindle (24) for biasing the spindle (24) in the first position while fluid pressure is less than a set pressure.
