Title: Method for detecting leakage in a fuel hose assembly, and fuel hose assembly for supplying fuel to a propulsion engine of a vessel.
Inventor: GERD JAN VAN DE POL
IPC: H01F7/16
Filed: 2015-05-27
Abstract: A method for detecting leakage in a fuel hose assembly, as well as a corresponding fuel hose assembly. A first hose for transporting a liquid fuel at a fuel pressure (Pf), substantially above ambient pressure Pa, is surrounded by a second hose, such that an annular chamber is formed between said hoses. Said chamber is filled a gas at a predefined reference pressure (range) (Pr), such that Pa < Pr < Pf. The pressure (P) of said gas in said chamber is measured and compared to said predefined reference pressure (range) (Pr). An error signal (S1, S2) is emitted when said measured pressure (P) deviates from said reference pressure (range) (Pr). Specifically, an error signal (S1) to indicate leakage in said first hose is emitted when P > Pr,, and an error signal (S2) to indicate leakage in said second hose is emitted when P < Pr.

Title: Sol. matl. extn. from solids, e.g. for sugar beet - by countercurrent contact with liq. in compartmented rotating drum
IPC: B01D11/02
Filed: 1975-10-14
Abstract: A plant for extracting solid materials by countercurrent contact with a liq. incorporates a horizontal rotatable drum with an outer shell in which are an axial central cylindrical duct and two internal shells, one near the outer shell and one near the duct. Between the two internal shells are radial partitions extending the length of the drum and forming compartments, each in section a segment of a circle, the apex of which is at the axis. the internal shells and the partitions are permeable to liq. In the central duct a fixed support carries pipes which feed liq. to the compartments and carriers arms terminating in rollers which rotate against the inner surface of the duct. The drum has a cover at one end, in the form of a truncated cone, with a hole in the small apex through which liq. leaves and which determines the level of liq. in the drum, below the axis. At the large base of the cover is a screen with an opening in its lower part. Solids are charged to this opening by a pipe leading from a screw conveyor in a feed hopper, pass along the compartments, where sol. material is extracted, and are discharged by a screw conveyor at the outlet end. Method is esp. useful for extracting sugar from sugar beet or cane. The appts. is simpler in construction than existing plants and allows treatment of solid materials in relatively thin layers in compartments of which all the walls are filter surfaces and in which there is good contact between solid and liq. It allows of filling practically all the available vol. in the compartments, without risk of blockage during the flow.

Title: Oil slick sweeper vessel has inlet above bow nose - separator hold, and water discharge astern through bow drive-up force and wake suction
IPC: E02B15/04
Filed: 1982-05-13
Abstract: The sweeper vessel is provided with an inlet opening at the bow end and contains oil sepn. means to receive water with high oil content entering during forward travel, separate as much water as possible, and discharge this via a stem opening whilst retaining the oil. This discharge is due to the level difference resulting from the upward driving action of the forwardly extending pointed bow and the suction in the wake of the vessel as this moves forward. Discharge of the separated water is effected by forward travel of the vessel only and does not require pumps, thus minimising operating cost with max. reliability.
