A tank container for bulk storage of liquid materials is provided with with remote operated valves. The tank container comprises a storage vessel for bulk storage of liquid materials and having a height of about eight feet. The storage vessel includes an outlet valve proximate a bottom of the vessel, a fill valve at a top of the vessel, and a vent valve at the top of the vessel. A parallelepiped frame surrounds and is secured to the storage vessel for stacking and transporting of the tank container. A fill line includes an outlet connected to the fill valve and extending downwardly within the frame and an inlet proximate the bottom of the frame. A fill valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the fill valve for operating the fill valve remote from the top of the storage vessel. A vent valve actuator is mounted proximate the bottom of the storage vessel mechanically linked with the vent valve for operating the vent valve remote from the top of the storage vessel.

A compartment wall structure defines a fuel filler compartment that includes a tube receiving opening and a vent opening. A fuel receiving end of a fuel filler tube is located at the tube receiving opening of the fuel filler compartment. A fuel tank attachment end thereof is located outside the fuel filler compartment and is spaced apart from the compartment wall structure. An air vent structure is in fluid communication with the vent opening. The air vent structure defines a chamber opening connected via a vent line to a fuel vapor filter canister. Vapor from the fuel filler compartment is vented to the fuel vapor filter canister through the chamber opening. The air vent structure has a screen at the chamber opening to prevent entry of objects, such as, for example, insects and/or debris through the chamber opening.

An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface. The flapper valve also is provided with an actuating means to automatically open the flapper valve when the canister is mounted on the interface, which permits fluid to be drained from the canister when the fluid distribution system is being drained without disconnecting the canister from the interface.

To provide a fuel line joint capable of improving resistance to an external force in a joint configured to store a liquid fuel. A fuel line joint is equipped with an integrally formed main body portion that has a storage region configured to store a liquid fuel in a lower part thereof and has an opening portion above the storage region of the liquid fuel; a lid that is formed separately from the main body portion, is attached to the main body portion so as to close the opening portion of the main body portion, and is not connected to members other than the main body portion; and a plurality of mounting portions that is formed integrally with the main body portion and mounted to each of a plurality of pipes forming a fuel line.

A vent apparatus is described for providing filtered air intake and rollover protection for a fuel tank. The apparatus may include a housing configured to be coupled with the fuel tank, the housing including at least one air intake port and at least one air exhaust port. The apparatus may include an air intake filter disposed within the housing and configured to receive and filter air from the at least one air intake port. The apparatus may include a rollover protection valve disposed adjacent to the housing and configured to be located inside the fuel tank when the housing is coupled with the fuel tank, the rollover protection valve coupled with the at least one air exhaust port. The rollover protection valve may include a chamber and a plug configured to impede the flow of fuel from the fuel tank into the at least one air exhaust port.

A system comprises a non-transitory machine readable storage medium storing instructions and a database identifying a plurality of assets and a state of each asset. The instructions configure a processor for receiving updates to a distributed electronic ledger managed by plural peer processors. Each update includes an event or change affecting one of the assets. The peer processors verify portions of the ledger describing each event or change. At least one of the updates has not yet been recorded in the ledger at a time of the receiving. The processor computes a state of each asset, based on the updates, receives a request for a state of one of the assets; and responds to the request, reflecting each event and change affecting that asset. The response is performed without waiting for the peer processors to verify an update that has not yet been recorded in the ledger.

An expansion tank includes a tank body mounted inside a housing forming a sump, and defining an internal expansion volume. A fluid inlet opening in the tank body is in communication with the sump and the expansion volume. A combination valve may be disposed on a lower end of the tank to control fluid flow between the sump and the expansion volume. The valve may be a combination duckbill valve and umbrella valve. Fluid enters the expansion volume through the umbrella valve when sump pressure exceeds expansion volume pressure by a first predetermined amount, and fluid exits the expansion volume through the duckbill valve to the sump when expansion volume pressure exceeds sump pressure by a second predetermined amount. The tank body may include a cover on which an inlet tube is formed.

The mounting structure of a fuel device is for mounting the fuel device, which includes a plurality of components, on a baffle plate for suppressing waving of liquid fuel stored in a fuel tank. One of the components of the fuel device is integrally formed, as a mounting portion, with the baffle plate. The remaining components of the fuel device are mounted, as a mounted portion, on the mounting portion of the baffle plate.

A liquid tank system comprises a main liquid tank, an outlet communicating between a fluid circuit and the main liquid tank, an inlet communicating between the fluid circuit and the main liquid tank, and an auxiliary cavity. First vent passage and second vent passage(s) communicate between the main liquid tank and the auxiliary cavity and allows liquid and gas to flow from the main liquid tank to the auxiliary cavity. The second vent passage has a flow control device regulating flow through the second vent passage and having a set point at which it allows liquid and gas to flow from the main liquid tank to the auxiliary cavity only when a pressure in the main liquid tank is beyond a threshold. The liquid tank system has an attitude envelope in which the liquid tank system is configured such that, in use, the flow control device blocks flow through the second vent passage when an end of the first vent passage in the main liquid tank is above a liquid level, and the flow control device allows gas and/or fluid flow through the second vent passage when main fluid tank pressure is above the threshold and the end of the first vent passage in the main liquid tank is below the liquid level.
