Abstract: A hydraulic device is provided herein. The hydraulic device mainly contains a reservoir having an airbag inside. The reservoir is provided with an inlet pipe and a plurality of outlet pipes, both extended from a top side of the reservoir. The inlet pipe receives water from a pumper and fills the reservoir via a back-pressure valve. The airbag expands by the air driven by an air compressor to force water from the reservoir into the outlet pipes. When the water level of the inlet pipe is higher than that of the outlet pipes, due to the siphon principle, water will continuously flows from the inlet pipe, through the vacuumed reservoir, into and then out of the outlet pipes. The water poured out of the outlet pipes can be utilized for hydroelectricity or irrigation.

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 As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted.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.

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.

The system further includes a source of compressed gas in fluid communication with the discharge port. A discharge rod is connected to the discharge port for delivery of remedial fluids to underground soils.

Abstract: A reliable and economical apparatus for relieving pressure in a large aircraft cabin oxygen supply, where multiple oxygen cylinders are used concurrently. A series-parallel array of valves actuated by changes in differential pressure between the oxygen supply and the ambient cabin atmosphere provides overpressure relief The series connection of the valves reduces the risk of open-valve failures, while the parallel connection of sets of series-connected valves reduces the risk of closed-valve failures. The small number of valves used in its design reduces the cost of the apparatus. The series-parallel structure is optionally extended to larger numbers of valves to facilitate the use of less-expensive valves and supporting components without loss of reliability.

Abstract: A dual fuel tank (10) including first fuel tank (12) and a second fuel tank (14). A single fuel hose (16) allows fuel to enter the first fuel tank (12) from an outside source. When the fuel level in the first fuel tank (12) reaches an overflow level (17), fuel passes through a transfer tube (18) from the first fuel tank (12) into the second fuel tank (14). A transfer fuel pump (20) communicates fuel from the second fuel tank (14) to the first fuel tank (16) such that the level of fuel in the first tank (12) is maximized relative to the available fuel in the system. A main fuel pump (22) communicates fuel from the first fuel pump (12) to a remote target (24). In this way the fuel is available from a single location within the dual fuel tank (10) at a wider range of angles of vehicle travel.

Abstract: An aircraft fuel tank (101) comprises an inner and an outer chamber (103, 105) which are fluidly interconnected via a plurality of open-ended pipes (109). A non-flammable gas, which is immiscible with the fuel (119), is pumped into the outer chamber (103) on demand to displace the fuel (119) into the less vulnerable inner chamber (105) and thereby forms a protective non-flammable gaseous barrier around the fuel-retaining inner chamber (105). The fuel tank (101) is used primarily for military aircraft and provides the ability to attenuate hydrodynamic ram effects arising in the fuel following penetration of the fuel tank (101) by a projectile. All round protection is achieved because the inner chamber (105) is contained wholly within the outer chamber (103).

Abstract: To produce a high pressure stream of fluid, such as propellant, the fluid is transfered from a low pressure reservoir into a plurality of intermediate storage tanks, in which the fluid is pressurized. The fluid is drained from the storage tanks to an outlet in sequence.

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.

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.

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.

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.
