  • Patent number: 5339759
    Abstract: A ventilator wind scoop system is disclosed for attachment to a boat deck hatch having a hinged hatch cover which opens to uncover the hatch opening whereby the scoop system communicates through such opening with the boat's below deck space. The scoop system has a flexible air entrance unit formed of first and second fabric panels fixed in line contact with each other along their forward edges. The first panel, which is positioned forward and over the front edge of the hatch cover, contains a screened, rectangular opening through which air passes to flow over the top of the second panel that extends under the hatch cover and between two triangular side wedges. The second panel provides a louvre that collects any water entering the screened opening and carries it forward, away from the hatch opening. The wind scoop system is easily customized to fit a wide variety of hatch sizes and when not is use folds into a compact size for easy stowage.

  • Patent number: 5306183
    Abstract: A propulsion system for a submarine vessel includes a thruster including a magnetic flux generating stator, a shaftless propellant rotor, electrical conductors to supply electrical current to the thruster, an electronic controller to regulate such electrical current and a mounting unit to attach the thruster to the vessel. The stator includes a plurality of magnetizable pole pieces each associated with windings of conductive wires electrically connected to a power supply via the controller. The rotor includes a propeller ring containing a plurality of permanent magnets to be torqued by the magnetic flux from the stator pole pieces and a plurality of propeller blades. The rotation of the rotor (armature) provides position signals to the controller which then energizes the proper field windings of the stator to continue the motion and provide full torque regardless of rotor speed.

  • Patent number: 5295762
    Abstract: A method of operation of marine locks includes the steps of supporting a first column of water within a lock chamber upon a vertically movable first floor, supporting a second column of water within a balance chamber upon a vertically movable second floor, supporting the first and second floors upon a confined volume of compressed air communicated between the lock chamber and the balance chamber and causing the first floor to rise or fall by application of upward or downward hydraulic pressure on the first floor while causing the second floor to move in the opposite direction by application of contrary hydraulic pressure on the second floor. Lock systems to perform the new methods are disclosed.

    Abstract: Methods and systems of the prior art for cleansing a plurality of seriate filter cells in automatic backwash filters by backwashing the cells one at a time with backwash liquid wherein the cleansing operation on the active cell is prevented from moving to a further cell until the contaminant content of the waste liquid issuing from the previous cell reaches a predetermined low level are improved by overriding such prevention even though such content remains too high when a prescribed quantity of waste liquid has issued from the previous cell, e.g., as determined by a timer or fluid meter.

  • Patent number: 5280685
    Abstract: A device for attachment to a tractor or similar vehicle for safe spray application of liquid chemicals around trees or like plants basically includes an elongated boom unit and a multinational spray unit pivoted by its inboard end on the boom unit, formed of an inboard section and an outboard section. The outboard section carries a spray nozzle and is pivoted by its inboard end to the outboard end of the inboard section. Spring members normally bias both sections of the spray unit into alignment with the boom unit, but first allow the inboard section followed, in turn, by the outboard section to move out of such alignment so they partially encircle a tree as the spray unit of the device contacts the trunk of the tree while the tractor moves the device forward and past the tree. Proximity switches and a photocell sense the correct positioning of the tree to emit sprayed chemical from the nozzle only when the spray unit is in contact with the tree.

  • Patent number: 5259639
    Abstract: A system is disclosed for towing a pair of four wheel vehicles having handlebars for steering, e.g. an ATV, behind a van or other tractor vehicle. Such system includes an elongated tow bar that carries first and second hitchballs on its end portions. For each towed vehicle, there is a hitch unit with a cuplike forward end that rotatably engages a hitchball so that the hitch unit can be pulled forward by the hitchball while being free to oscillate behind it. The hitch units are fastened to the front ends of the four wheel vehicles and spring members are connected to each left and right handlebars of the four wheeled vehicle being towed to elastically bias them into the position that causes the respective the four wheel vehicle to move straight ahead, but momentarily allows the front wheels to momentarily move out of such position to enable the towed vehicle to accommodate itself to turning movements made by the tractor vehicle.

  • Patent number: 5232585
    Abstract: An improved multi-stage treatment system for biological denitrification of and suspended solids removal from water includes a biological reactor containing rigid media supporting denitrifying bacterial growths, an aeration chamber and an automatic backwash filter. In use, methanol or other carbon source containing influent water flows into the reactor beneath the rigid media and upwardly in contact with said bacterial growths to cause nitrates and nitrites contained therein to be converted into nitrogen. The denitrified water is then aerated in the aeration chamber and subsequently filtered by downward flow through the automatic backwash filter.

  • Patent number: 5230162
    Abstract: In a freeze-drying method, liquid substances to be dried are sprayed into a stream of cold gas, usually air, at ambient pressure creating a collection of small frozen particles that are metered through a vacuum lock into a vacuumized vertical tower having heated walls and, as the particles fall through the vacuum in the tower to its bottom, radiant heat from the tower walls causes the ice contained in the particles to sublime. The resulting sublimed vapor is removed from the tower by low temperature condensation while the dried particles are collected at the bottom and transferred through another vacuum lock into a container. The operation is continuous and fast, providing significant advantages compared to prior known freeze-drying operations.
