  • Patent number: 5070803
    Abstract: A trolling speed reduction apparatus for slowing the trolling speed of boats having an inboard engine and a steerable rudder mounted under the stern of the boat aft of a propeller driven by the inboard engine. The rudder has first and second opposed major sides and has first and second deflector plates carried on opposite sides of the rudder. The deflector plates are moveable between a first, closed position wherein the first and second deflector plates reside closely adjacent to an substantially along the respective first and second major sides of the rudder and are substantially inoperative and a second, open position wherein the first and second deflector plates extend outwardly away from the opposed sides of the rudder into the wash from the propeller and are operative to create speed reducing drag to slow the forward movement of the boat.

  • Patent number: 5058521
    Abstract: A submarine hull which has a half wing-like sail which projects vertically upwards, is provided with a keel-wing that also is half wing-like, but projects vertically downwards. By preference the keel-wing has a lower end plate and its main portion is trailed by two slotted flaps which can be pivotally moved in both directions about respective vertical axes in coordination with movement of the rudder of the submarine. If needed for permitting operation in shallow water or with the hull close to the bottom, the wing can be made to retract. The keel-wing not only counters the sail's rolling movement and keeps the hull upright, but also adds a side force to assist in tightening the turn.

  • Patent number: 5056450
    Abstract: A personal watercraft having a selectively extendable and vertically pivotable steering set up is disclosed. The watercraft hull includes a channel for slidably receiving and engaging a steering arm to which a steering handlebar is mounted proximate one end and opposing protuberances formed proximate the opposite end. When the steering arm is fully extended retention means associated with the channel engage the protuberances so as to provide a pivotal connection. In an alternative embodiment the steering arm is selectively vertically rotatable and telescopically extendable.

  • Patent number: 5054410
    Abstract: A multi-hulled sailing vessel is provided with a pair of aileron foils that are mounted outboard from each of two sponsons that are rigidly joined to a central main hull. The aileron foils are rotatable about axes that are inclined toward each other when deployed. Each of the sponsons is provided with a mast carrying a sail. The masts are coupled together by a pair of transverse stabilizing struts. The masts are each supported by separate shroud systems. The vessel is equipped with load sensing and foil control means coupled to at least some of the shrouds and to the aileron foils so as to rotate the aileron foils about their axes responsive to loads in the shrouds. A rudder at the rear of the central main hull is provided with a transversely mounted elevator foil which is also rotated about an axis transverse to the rudder responsive to loads in the shrouds. The foils and the rudder are mounted for rotation relative to the sponsons and the central main hull and can be brought entirely out of the water.

  • Patent number: 5051040
    Abstract: A fluidized bed combustion system that can be operated or controlled under pressure is provided. To eliminate the erosion or abrasion to which heat exchangers located in a fluidized bed combustion chamber are subjected due to the flue dust contained in the flue gas, no thermal withdrawal or exchange takes place in the combustion chamber of the inventive fluidized bed combustion system, although the reaction conditions remain the same. At least one controllable line for returning to the combustion chamber part of the flue gas, if necessary cooled by heat exchangers variously arranged outside the combustion chamber, branches off from the flue gas line downstream of a dust separator that is disposed in the flue gas line downstream of the combustion chamber. The main area of application is the production of electrical energy and heat for the generation of steam, as process heat, or as heat for a remote site, by means of a fluidized bed combustion system that can be operated or controlled under pressure.

  • Patent number: 5050525
    Abstract: An underwater gamma radiation survey probe adapted to be towed by a tow cable along the bottom of a body of water. The probe comprises a tubular shell with a nose cone having a waterproof connector for the tow cable. The nose cone closes one end of the tubular shell in a waterproof manner and an end plug closes the other end of the tubular shell in a waterproof manner. At least one weight of high density material is located in a lower half of the shell with that weight containing a cavity having an opening which faces the tubular shell. The weight maintains the orientation of the probe such that the opening faces downwards and a radiation detector in the cavity can detect radiation from the bottom surface.

  • Patent number: 5041031
    Abstract: A swimming frame for competition in swimming, swimming instruction, muscle strengthening, and entertainment in the water comprises a pair of floats (1), a clamping unit (2, 3), and a paddle unit (4, 5, 6). It might be used by everyone regardless of the ability to swim. The paddle unit might by modified giving an additional possibility to practice butterfly-like and crawl-like style of swimming. A swimmer being clamped between rigid (2) and flexible (3) portion of the clamping unit is producing the push-pull movements of the paddle unit. When he pushes the unit, the paddle (4) is rotated up to horizontal position by the water pressure against its front. When he pulls the unit, the paddle is rotated up to vertical position by water pressure against its back. Because of the difference in the paddle hydroresistance between push and pull movements the swimming frame will be propelled by the swimmer.

  • Patent number: 5038697
    Abstract: An improved version of the Float Connection Assemblies as described in U.S. Pat. No. 3,937,166, for the retraction of a trimaran's stabilizing floats to be alongside the trimaran center hull for trailering or Marina docking. The improvement consists of a variable length Upper Pivoting Guide Frame, that when varied in length will allow a trimaran float being retracted by the Float Connection Assemblies to assume a different, higher and more favorable position, to prevent marine growth on the floats' sides, particularly the topsides above the normal waterline when retracted.This allows a trimaran incorporating this improved Float Connection Assembly to be easily converted from a trailerable configuration, to a more suitable Marina docking configuration, without the problem of underwater growth on the retracted float's side.
