  • Patent number: 7325503
    Abstract: A lift for a watercraft has plastic reinforcing brackets which engage in pockets in the thin-walled plastic floatation tanks of the lift and which provide mounting flanges at the top surfaces of the floatation tanks for abutment with mounting pads which connect to the watercraft support frame. The brackets are engaged on the floatation tanks and the pads overlap and are bolted to the plastic brackets, so that the pads are locked against but not bolted to the floatation tanks. Thus, the integrity of the tanks is not compromised by assembly-associated openings through the tank walls. Furthermore, the bolts are above the tank waterlines so that no corrosive material is disposed below the waterlines.

  • Patent number: 7293522
    Abstract: A roller assembly facilitates travel of a watercraft hull on a floating dock having a longitudinal, keel-receiving valley with a pair of flanking ridges supporting opposite sides of the hull during docking and launching of the craft. Pockets in the ridges contain wheels mounted on circumferential planes parallel to the ridges for rotation on axles seated in the pockets. The upper portions of the wheels protrude above the crests of the ridges and the axle end bearing portions cooperate with the seats in the pockets to list the circumferential planes toward the valley and approximately perpendicular to the hull sides. For optimal performance, two or more roller assemblies can be arranged in-line and spaced apart longitudinally in each of the ridges. A brake stops the docking motion of the watercraft onto the dock. Multiple docks can be serially connected without use of special tools or underwater assembly steps.

  • Patent number: 7191722
    Abstract: For indicating the absence of a drain plug from a boat drain when the boat is in a launch condition, a receptacle with a water flow passage and a cavity containing a Hall effect switch is mounted in the boat drain. A stopper has a magnet which operatively aligns with the Hall effect switch when the stopper plugs the passage. The Hall effect switch and a switch operated in response to a presence-of-water condition are components of a control circuit which drives a switch to connect and disconnect an audio alarm activation device to and from an electrical power source. The alarm will always be activated when the stopper is not in the drain and the presence-of-water switch has operated and will never be activated when the stopper is in the drain.

  • Patent number: 7147683
    Abstract: A valve and trigger cyclically connect a vacuum and a blower to a filter. The valve box has three openings, the first connectable to the vacuum, the second connectable to the blower and the third connectable to the filter. A gate inside the box, biased by the blower and the vacuum toward closing the first opening, is held against the bias by a trigger outside the box to close the second opening. The external trigger intervally operates to release the interior gate to close the first opening and open the second opening. The blower operates only if the trigger is operating. The gate is released once for approximately 1/12 of a cycle interval during each trigger operating interval. A plurality of valves can be combined in a system with one trigger for cyclically sequentially connecting a plurality of filters to the vacuum and the blower.

  • Patent number: 7093417
    Abstract: Rope is made from one or more rolls of film. The rolls of film are loaded onto spindles and tension is applied to the free end of the film of each roll to dispense the films. The dispensing films are each constricted at a common focal point of tension to create substantially triangular portions defined by the line of departure of the film from its roll and the focal point of tension. The triangular portions of each film are continuously simultaneously preconditioned, as by heat or humidity, as the films are dispensed. The rolls are also continuously rotated during dispensation about a common axis which is skewed in relation to the dispensation axes of the rolls, causing the preconditioned films to twist at the focal point of tension into a strand of rope. The strand of rope is then rounded and post-conditioned, perhaps by water or air cooling, and coiled for storage.

  • Patent number: 7035413
    Abstract: A dynamically variable spectral matrix surround system decodes two-channel stereo into multi-channel surround. In one embodiment, the true stereo signal is present in left and right front and left and right surround channel outputs. When a dominant center channel signal appears, the system subtracts center channel audio from the critical voice band only. The higher frequency portion of the spectrum will remain true stereo at all times. In another embodiment, the front center signal bandwidth is determined. A dynamically variable portion of the audio spectrum is inverted and added to the opposite channel, thereby dynamically subtracting the bandwidth of the front center signal from the left front, left surround, right front and right surround channels but leaving the portion of the audio spectrum that does not contain front center information unaltered. The input is divided into two frequency bands.
