A tank tube bracket for a tank comprises a receptacle extending along an axis and receiving a tank tube and a passage adapted to pass a fluid through the tank tube bracket. A distal end of the passage is directed toward the axis of the receptacle.

A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

A fuel tank joint includes a tubular joint body and an entry restriction member. The joint body includes a support portion. The entry restriction member includes a body tube, a groove, a guide, and an engagement hook. The body tube has opposite open ends in the flow direction of fuel. The groove extends upstream from the downstream end of the body tube and is engaged with the support portion. The guide is formed in part of the body tube that includes the downstream end of the body tube and guides the groove to the support portion by contacting the support portion when the body tube is inserted into the joint body. The engagement hook is formed in a downstream end section of the body tube and engaged with the support portion, from a downstream side, in a state in which the groove is engaged with the support portion.

The present invention relates to a fuel tank arrangement of a marine vessel including a fuel tank for Liquefied Natural Gas, the fuel tank having a shell, a heat insulation in connection therewith, connections for a pipeline for bunkering LNG to the fuel tank, a pipeline for taking boil-off gas from the fuel tank and a pipeline for taking LNG from the fuel tank, and a deep well pump for pumping LNG from the tank to the pipeline, wherein at least one recess is extending inwardly from the shell and being arranged on top of the fuel tank, the deep well pump being installed in the at least one recess.

A cutting fluid tank includes: a fluid ejection apparatus configured to eject fluid toward cutting fluid containing chips and to be capable of varying at least one of a direction and a position of ejection with time in an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The fluid ejection apparatus includes an ejection head having an ejection port rotatable about an axis of rotation. The ejection port is at a twisted position with respect to the axis of rotation, and the ejection head is rotated by a reaction force of the fluid ejected from the ejection port. Part of the cutting fluid stored in the cutting fluid tank is used as the fluid to be ejected from the ejection port.

A thermal energy storage installation including a thermal energy storage tank and a spider diffuser system mounted in said tank. The TES tank comprises an outer wall having a generally cylindrical inner surface surrounding a hollow internal space in the tank. The spider diffuser system comprises a centrally disposed manifold structure that is disposed in vertically spaced relationship relative to a thermocline formed in a temperature stratifiable liquid in the space during operation of the tank. The manifold structure has an internal chamber and includes an opening for introduction of a said liquid into the chamber or discharge of a said liquid from the chamber. The spider diffuser system also includes a diffuser pipe assembly comprising a plurality of elongated diffuser legs. Each of the legs is attached to the manifold structure so as to extend generally radially outwardly from the structure and toward the inner surface of the tank. Each of the legs has an internal channel in fluid communication with the chamber. Each leg also has a plurality of apertures distributed along the length thereof, which apertures intercommunicate the channel with the space.
