  • Patent number: 10821740
    Abstract: The invention relates to a method for printing a surface (2) with a fluid which contains an organic semiconductor material. The fluid is transported from a storage container (7) through a supply line (5) to a printing head (3), which can be moved over the surface (2), and printed onto the surface (2) by the printing head (3). At least one part of the fluid which is transported through the supply line (5) to the printing head (3) is returned to the storage container (7) via a return line (6), wherein a fluid circuit is formed, and the fluid in the fluid circuit flows through a cleaning device (12) with which the fluid is cleaned. The fluid returned to the storage container (7) flows around and surrounds the fluid being transported in the supply line (5) to the printing head (3) at least in some regions.

The substantially planar discharge presents a very large surface area for its volume and induces water adjacent the outside of the shell of the driving unit to move upwardly with it toward the surface of the body of water.

  • Patent number: 8991422
    Abstract: A diffuser assembly for a hydraulic reservoir is disclosed. The diffuser assembly includes an inlet tube for connection to the inlet to the reservoir. A middle portion of the middle tube is connected to a plurality of diffusers. The diffusers are disposed at an angle with respect to an axis of the inlet tube and the axis of the inlet to the reservoir so that fluid flowing into the reservoir must change flow directions for entering and exiting the diffusers. The disclosed diffuser assembly is less prone to damaged cause by fluid flow spikes and is particularly useful for high flow/high pressure applications.

    Abstract: A subsea system is for uptake and supply of a liquid. The system comprises a storage tank having at least one outlet, a valve assembly, a pump having a high-pressure side and a low-pressure side, and a feed line. The outlet is in fluid communication with a lower internal volume of the tank, and the valve assembly. The low-pressure side of the pump and the feed line are in fluid communication with the outlet, and the valve assembly is arranged on the feed line, and the feed line is bypassing the pump, such that said pump may withdraw liquid from the tank when the valve assembly on the feed line is closed.

  • Publication number: 20150017332
    Abstract: An apparatus and method for supplying virgin sealer and reclaim sealer to a sealer applicator. A closed loop path including a first fluid flow path is coupled between a source of virgin sealer and the applicator and includes a recirculation path from the applicator back to the source of virgin material. A reclaim sealer supply is coupled to the first fluid flow path. Valves open and close the virgin sealer supply and the reclaim sealer supply to alternately supply virgin sealer or reclaim sealer to the applicator. Whenever the first fluid flow path contains reclaim sealer, a valve blocks flow to the recirculation path to prevent reclaim sealer from being recirculated into the source of virgin sealer.

  • Patent number: 8863986
    Abstract: A dispensing apparatus for dispensing predetermined volumes of fluid into receptacles receives the fluid to be dispensed from a fluid supply into a reservoir. A fill tube is connected to the fluid reservoir such that it forms a closed loop with the reservoir. The fill tube minimizes the fluid turbulence that occurs inside the reservoir while the reservoir is being re-supplied with fluid from the fluid source. Additionally, the fill tube holds the predetermined volume of fluid to be dispensed into the receptacle. A fluid level sensor is disposed along the fill tube to control the volume of fluid flowing into or out of the fill tube, while a timer controls a dispense valve to meter the flow of fluid into or out of a dispense tube.
