  • Patent number: 7201178
    Abstract: A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.

  • Patent number: 7168442
    Abstract: A liquid handling system transfers liquid (e.g. water, bearing marine animals) between two tanks each having a respective liner which is movable between a lining position (when filled with liquid) and an inverted position (when its respective tank is emptied). In an initial state, liquid is held in a first tank. By supplying air to a space between the first tank and its liner, its liner is progressively lifted and liquid passes along a channel onto the initially inverted second liner (which acts as a baffle to slow the liquid flow). Air in a space between the second liner and the second tank is vented so transferred liquid sinks the second liner to fill the second tank. A ballast liquid may be used in the spaces. Initially held in the second tank, the ballast liquid flows via a passage into the first tank as transfer of liquid progresses.

    Abstract: In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

  • Patent number: 6240868
    Abstract: A marine gas storage and transport system formed of small diameter steel pipe, which is coiled and stacked in a specific manner. The system is suitable for use on top of a barge or inside the holds of a ship, when contained within a secondary containment system. The specific manner in which the pipe is coiled is such that about 97% of the total length of pipe coiled may be described by constant curvature or pure circles. Additionally these circles lie directly on top of one another about 94% of the time and vertical stacking stresses are minimized. Only about 6% of the pipe is involved in crossover geometry. This method, of about 97% circular coiling, combined with about 3% transitional coiling results in a continuous length of pipe that nests easily, provides greatly reduced contact stresses and is very economic to construct due to its ease of nesting and it's long lengths of constant curvature.

  • Patent number: 6209594
    Abstract: In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

  • Patent number: 6158485
    Abstract: In the case of a filling device for a motor vehicle fuel tank, a distributing element extends from a filling nozzle to an anti-surge tower of the motor vehicle. When there is a low volume flow of fuel in the filling nozzle, the distributing element supplies all of the fuel to the anti-surge tower. When there is a large volume flow, the greater part of the fuel passes directly into the fuel tank. It is thereby ensured that during an initial filling or emergency filling with a jerrycan, virtually all of the fuel passes into the anti-surge tower.

  • Patent number: 6058954
    Abstract: It is known to supply solution to a process and to collect effluent therefrom using `bag-in-box` arrangement each having a predetermined volume. However, if the process must be supplied with greater volumes of solution, the use of larger `bag-in-box` arrangements is limited by weight restrictions that an operator can handle. Described herein is a method of using a number of `bag-in-box` arrangements coupled together to provide a larger volume of replenisher solution to a process and to collect of effluent therefrom than would be the case if only a single `bag-in-box` arrangement is used. An automatic changeover system can be utilised which allows the process to be supplied with a greater volume of solution than that which corresponds to the legal weight limit without having to empty the supply `bag-in-box` arrangements into a large replenisher tank.

  • Patent number: 5653255
    Abstract: A sewage treatment system includes a pair of substantially identical unitary fluid treatment modules, each module having a central sedimentation tank surrounded by a peripheral wetland. The sedimentation tanks are coupled through a dosing device to an input source of sewage and, as an outlet, to a leaching field. The dosing device includes a switching mechanism isolated from the fluids, which mechanism provides in one cycle for one treatment module to be filled with the incoming sewage while maintaining its outlet closed. When the liquid level in the sedimentation tank in the first treatment module reaches a predetermined level the dosing device switches the sewage input to the other treatment module, while opening the outlet from the first treatment module to the leaching field. The dosing device switching mechanism employs pinch valves arranged so that when the inlet on one treatment module is closed, the inlet on the other treatment module is substantially simultaneously opened.
