A liquid supply device includes a liquid discharge head, a main tank, a first sub-tank, a second sub-tank, a first channel, a degassing device, and a second channel. The liquid discharge head is configured to discharge liquid. The main tank is configured to store liquid to be supplied to the liquid discharge head. The first sub-tank is configured to store gas and liquid and connected to the main tank and the liquid discharge head. The second sub-tank is configured to store gas and liquid and connected to the first sub-tank and the liquid discharge head. The first channel connects between the main tank and the first sub-tank. The degassing device is configured to degas liquid in the first channel. The second channel connects between the second sub-tank and the first channel.

A fluid transfer device is implemented which has an inlet for receiving a fluid from a subject container or reservoir and an easily controllable outlet to direct the received fluid to a desired location, such as a target container or reservoir. The inlet and outlet may both include conical spouts to which various sized hoses can removably attach to enable directional and maneuverable control for a user. The fluid transfer device includes a base which rests on a surface and provides support for the components above it, including a handle and an operational arm that handles the fluid transfer operations. The fluid transfer device is configured with versatility for adaptability to multiple use cases. For example, the fluid transfer device has a height-adjustable handle to accommodate differently sized containers, a hinged operational arm, and a horizontally-adjustable container rest.

An environmentally-friendly test port mounting in a conventional gasoline/diesel fuel dispenser cabinet to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system. The technician may access the test port while the line system head pressure s maintained at a point above ground. The test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

An apparatus for the production of red wine is provided. This compact device is suitable for home and hobby use. The fermenting wine is contained inside a single-use plastic bag, eliminating cleaning. A reusable rubber bladder is inflated periodically to squeeze the cap and disperse it. At the conclusion of the fermentation, a perforated device is inserted into the fermentation bag and pneumatic bladders are sequentially inflated to press out the wine while retaining the waste skins and seeds.
