In another embodiment, a breaker clamp includes two breaker clamp members.

To provide a safety joint capable of preventing a component of a weighing machine side member or a vehicle side member is broken in case that the weighing machine side member and the vehicle side member are separated from each other in an emergency when a vehicle runs while hydrogen gas is filled for instance. The safety joint (100) according to the present invention includes a plug (10) with a cylindrical shape in which a passage (1A) is formed, a socket (20) in which a passage (21A) continuing to the passage (1A) in the plug (10) is formed, and a shut off valve mounted on the passage (21A) in the socket (20), the shut off valve opening when the plug (10) being inserted into the socket (20) and closing when the plug (10) being disconnected therefrom, wherein central axes of the passages (1A,21A) of the plug (10) and the socket (20) do not form a straight line, a cover (50) for protecting a valve rod (2) mounted on one of the plug (10) and the socket (20) is mounted.

A breakaway coupling includes a body and a valve assembly inside the body. The body includes a fluid conduit and a shear groove between first and second portions. The shear groove is designed to crack, break, or separate under certain conditions. The valve assembly is designed to shut off fluid flow through the fluid conduit when the shear groove cracks, breaks, or separates. The valve assembly includes a valve seat, a sealing element, one or more pins, and a biasing member. The one or more pins hold the sealing element in an open position while the shear groove is in tack, and allow the sealing element to move to a closed position (with the help of the biasing member) in the event the shear groove cracks, breaks, or separates.

To provide a fluid supply apparatus capable of preventing inconveniences cause by cut of a signal line when a filling hose is separated through an emergency separation pipe joint. The fluid supply apparatus (100: fluid supply apparatus for supplying fluid such as hydrogen gas and gasoline) includes a supply system for transporting fluid such as hydrogen gas and gasoline in a housing main body while measuring flow rate of the fluid; a control mechanism for controlling the supply system; a hose (2) introduced from the supply system and having a nozzle (1) at an end thereof; and a signal line (3) along the hose (2), wherein the signal line (3) is detachable.

The present invention relates to a pneumatically, high pressure gas powered emergency release coupling control and monitoring system (S) comprising a powered emergency released coupling (1) arranged in a fluid-supply line (32) for conveying hazardous fluids, said powered emergency released coupling (1) comprising a couple of coupling members (10, 11) provided with mating faces (10A, 11A) for sealing engagement of the coupling members (10, 11) and formation of a pressurizable chamber (12) between said coupling members (10, 11), said system (S) comprising an actuation line (7) connected at its one end to the pressurizable chamber (12) and at its other end to a source (C) of high pressure gaseous media (G.sub.H), preferably high pressure nitrogen gas, an first actuating device (4A, 4B) arranged in the actuation line (7), wherein said system (S) provides a gaseous media at a pilot pressure level to said pressurizable chamber (12) and to said actuation line (7) in a position downstream the first actuation device (4A, 4B) or via said pressurizable chamber (12) for detection of any leakage of gas in the control and monitoring system (S), said pilot pressure gaseous media preferably being low pressure nitrogen gas. The invention further relates to a pneumatically, high pressure gas powered emergency release coupling (1) and a control and monitoring method for such a system (S).

A valve arrangement for a hose end coupler of a transfer hose for the offloading of hydrocarbons from an offshore floating production storage and offloading vessel (FPSO) to a shuttle tanker is described. The valve arrangement comprises a linear valve comprising a linear valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; a secondary valve comprising a secondary valve actuator movable between a first position whereat the valve is closed and a second position whereat the valve is open; the linear valve actuator and the secondary valve actuator are operatively coupled so movement of the linear valve actuator effects a corresponding movement of the secondary valve actuator. A hose end coupler with the valve arrangement, and a transfer hose and transfer system and method incorporating such a hose end coupler with the valve arrangement are also described.

A breaker clamp member includes a curved body shaped to fit around a portion of an upper portion of a fire hydrant and a portion of a lower portion of the fire hydrant at a joint between the upper portion of the fire hydrant and the lower portion of the fire hydrant. The breaker clamp member also includes at least one connection element extending from the body to connect the breaker clamp member with at least one other breaker clamp member. The breaker clamp member also includes an upper rim protruding from the body and a lower rim protruding from the body. The upper protruding rim, the lower protruding rim, and the body define a concavity therebetween, the concavity being configured to receive the first ledge and the second ledge. In another embodiment, a breaker clamp includes two breaker clamp members.
