Title: Floating apparatus and method for extracting power from sea waves.
Inventor: YEMM RICHARD
IPC: F03B13/20
Filed: 2001-03-13
Abstract: An apparatus for extracting power from ocean waves comprises a number of buoyant cylindrical body members (2, 3, 4) connected together at their ends to form an articulated chain-like structure (1). Each pair of adjacent cylindrical members is connected to each other by a coupling member (5a, 5b) which permits relative rotational movement of the cylindrical members about at least one transverse axis (40). Adjacent coupling members may permit relative rotation about mutually orthogonal transverse axes (A, B). Each coupling member is provided with elements such as a set of hydraulic rams (33, 34, 35) which resist and extract power from the relative rotational movement of the body members, and which can provide applied constraints to rotation about one or both of the transverse axes. The transverse axes of rotation (A, B) are skewed from the horizontal axis (104) and vertical axis (100) by a roll bias angle (psi), selected to optimize the dynamic response of the apparatus to incoming waves. The roll bias angle (psi) is applied by differential ballasting of the body members (2, 3, 4) and/or mooring constraints.

Title: Dual discharge valve.
Inventor: DAVID FROST DOUGLAS ROBERT
IPC: E03D1/14
Filed: 2003-01-23
Abstract: A dual discharge valve for immersion in fluid, in a cistern includes a housing having an upper portion and a lower portion. An upwardly movable main valve assembly within the housing forms therewith a variable volume upper chamber and lower chamber. A first vent means is between the upper and lower chambers and an outlet leads down from the lower housing portion, which portion contains a seat for the main valve assembly at the entry to the outlet so that in the lowered position of the main valve assembly the outlet is blocked against the ingress of fluid. A central stem extends upwardly from the main valve assembly and is actuable by a first operating means remotely from the upper housing to raise the main valve assembly off its seat, the wall of the lower portion of the housing above the seat having apertures. On raising the main valve assembly immersion fluid can enter the outlet, the net upward force thereby causing it to rise to the top of the upper chamber and permit full flow of the immersion fluid through the outlet. A second operating means is actuable remotely from the upper housing, to separately raise the main valve assembly off its seat and then exert a downward force on the main valve assembly, so that at a predetermined intermediate water level, the main valve assembly re-seats.

Title: Testing method, and method for passively obtaining target parameters
Inventor: ULRICH STEIMEL
IPC: G01S13/86
Filed: 2006-08-16
Abstract: The target, e.g. a submarine, ship or torpedo, is tracked from another vessel. All data are associated with a common time frame. With the aid of a land based- and/or satellite positioning system, readings of positions and bearings of vessel and target, are taken at intervals. From this data, positions, bearings and ranges are calculated. Data from the navigation system of the vessel is used to compute track positions of a preferably-smoothed reference target path. The target reference: path, bearings, positions, ranges and velocities, are used to determine a target reference course. By comparison with corresponding actual data (especially relayed by radio from target), a measurement of the discrepancy is derived.

Abstract: A nuclear-engineering installation has a pressurized-water reactor and a degasification system for reactor coolant. The degasification system has a degasification column which is coupled to the primary cooling circuit of the pressurized water reactor and further includes a coolant evaporator with a first heat exchanger and a stripping vapor condenser with a second heat exchanger, wherein a partial flow of the reactor coolant flows through the heat exchanger of the coolant evaporator on the secondary side, and wherein the heat exchanger of the stripping vapor condenser is connected, on the primary side, in a vapor and gas outlet line which is connected to the degasifier column. The degasification system is intended to be configured such that, with as simple a design as possible and taking into consideration relevant safety procedures, a particularly effective and at the same time energy-efficient separation of gasses, which are dissolved in the reactor coolant and cannot be condensed, is made possible, wherein the thermal load of the assigned nuclear intermediate cooling system is furthermore intended to be kept as low as possible. To this end it is provided that the heat exchanger of the coolant evaporator is switched in a heat-pump circuit on the primary side, which heat-pump circuit is coupled to the heat exchanger of the stripping vapor condenser with respect to the heat flux, which is established during plant operation, such that the heat liberated in the strip steam condensation is transferred at least partially to the reactor coolant, which flows through the coolant evaporator, and thus causes its evaporation.
