Improvements in a portable vehicle fueling kiosk is disclosed. The kiosk is constructed on a pallet or a skid that allows the kiosk to be placed, located or moved to a location where the fuel dispensing is desired. A fuel tanker that would normally dispense fuel to a storage tank of a gas station is connected to one side of the kiosk. The kiosk accepts payment by nearly any form of money, credit card or token to measure, dispense and bill or invoice the user. The kiosk can have a Wi-Fi or cellular communication to communicate with a user at a distance and can monitor, use, status and remaining fuel in the tanker. If a fuel tanker has been depleted additional tankers can be connected to the kiosk, and when the kiosk is no longer needed it can be transported to another location.

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 dental paste filling device for filling dental paste in a container without entraining air bubbles is disclosed. The dental paste filling device includes: a paste supply stage serving as a supply source of the dental paste; a paste filling stage where the dental paste is filled in the container; and a supply flow passage connecting the both stages. The paste supply stage comprises: a storage chamber for storing the dental paste; a storage chamber depressurizing and defoaming device for depressurizing the inside of the storage chamber to defoam the dental paste within the storage chamber; and a storage chamber extruding device for extruding the dental paste within the storage chamber towards the supply flow passage. The paste filling stage comprises: a filling chamber having an open/close mechanism; a holder for detachably holding the container inside the filling chamber; a filling chamber deaerating device for depressurizing the inside of the filling chamber to prevent entrainment of air bubbles into the dental paste; and a reception port for introducing the dental paste into the filling chamber. The supply flow passage comprises: an upstream tube connected to the storage chamber; a downstream tube connected to the reception port of the filling chamber, and a discharge control valve disposed between the upstream tube and the downstream tube.

Some embodiments disclosed herein provide flow path inserts that can redirect flow paths in syringes with axially aligned tips to an outer edge of the syringe. When connected in line with other components, air can become trapped in the system. The syringes can be positioned generally horizontally and air bubbles can be disposed within the body of the syringe. The air bubbles rise to the top or uppermost portion of the syringe. The flow path inserts can facilitate the transfer of the air bubbles disposed within the syringe out the flow path defined by the flow path insert. Some embodiments disclosed herein provide a spinning luer connector for connecting components of a fluidics system.

A liquid supply apparatus includes: a storing tank configured to store a liquid; a supply conduit through which the liquid remained inside the supply conduit flows reversely into the storing tank by a predetermined amount over time, the supply conduit having a first end portion connected to the storing tank; a liquid feeding section which is arranged at the storing tank or the supply conduit, and which is configured to feed the liquid from the storing tank to a second end portion of the supply conduit; a time measuring section which measures an elapsed time from stop of the liquid feeding by the liquid feeding section; and a control section which is connected to the liquid feeding section and the time measuring section and which is configured to drive the liquid feeding section for a predetermined time based on a length of the elapsed time.

The invention relates to a pumping system (2) for a fuel dispensing unit (1), comprising a first pumping unit (3) configured to suck fuel from a fuel storage tank and comprising a first air separator for circulating a part of the fuel with low rate of gas toward a first fuel supply line (15) and to evacuate a gas-enriched part of the fuel toward a first recovery chamber (18), a second pumping unit (4) configured to suck fuel from the fuel storage tank and comprising a second air separator for circulating a part of the fuel with low rate of gas toward a second fuel supply line (16) and to evacuate a gas-enriched part of the fuel toward a second recovery chamber (19), and a manifold (8) comprising a fuel inlet (34) connected to the fuel storage tank, a first fuel outlet (35) connected to a first supply inlet of the first pumping unit (3), and a second fuel outlet (36) connected to a second supply inlet (38) of the second pumping unit (4). The invention also relates to a fuel dispensing unit (1) for refueling vehicles.
