  • Patent number: 7914048
    Abstract: A coupling device that provides a liquid tight seal at the connection with a conduit with easy installation. The device comprises a tubular connector body, a compression nut, a first sealing ring, a second sealing ring, a ferrule, and a lock nut. The coupling device may be installed fully assembled and does not require disassembly of the packaged product before installation. In the connector body a radial ledge is formed within the tubular spaces between the first and second ends. The radial ledge of the connector body has at least one depression. The ferrule has a tubular body with a radial flange extending from a first end portion. At least one protrusion extends from the radial flange that corresponds to the depression on the tubular body. When the depression of the tubular body engages the protrusion of the ferrule, it restricts the ferrule from relative rotation. This restriction allows that the coupling device be installed fully assembled.

  • Patent number: 7828296
    Abstract: A multi-sports ball/disk return net system and a method thereof that consistently returns a ball/disk hit, kick, thrown or struck into it back toward a user and that is portable and easy to assemble and disassemble. The multi-sports ball/disk return net system has a frame and a net mounted on or across the frame. The net forms an upper U-shape forward bulging pillow having a square net pattern and a lower U-shape channel or hammock with the square pattern at the opposite ends of the U-shape channel being skewed to become diamond shapes. The net is configured to cause a projectile propelled into the U-shape pillow to drop down to the U-shape channel, which funnels the ball to the lowest and central point of the U-shape channel for discharge toward the user.

  • Patent number: 6770689
    Abstract: The glittering ink of the present invention contacts scaly glittering particles, a water-soluble resin, a water-soluble organic solvent, colorant and water. The said scaly glittering particles have a median diameter of at least 10 &mgr;m, a ratio of smoothness on the particle surface to a median diameter of not greater than 0.011, and a surface coating ratio of the said colorant in a written mark of not greater than 80% in a state of a dried written mark. In addition, the aqueous glittering ink of the present invention has the thixotropy index (T.I. value) of not less than 1.3, represented by the ratio of V0.5 to V1.0 (V0.5/V1.0), wherein V0.5 is the viscosity with the rotation speed of 0.5 rpm and V1.0 is the viscosity with the rotation speed of 1.0 rpm when the ink is measured by an ELD-typed viscometer (3° R14 cone, at the temperature of 20° C.) and the ink has the V0.5, the viscosity with the rotation speed of 0.5 rpm, of 1000˜15000 mPa·s.

  • Patent number: 6751823
    Abstract: A brush tip for a motorized toothbrush has a first brush head and a second brush head. The second brush head encircles the first brush head. A shaft has two cranks, each engaging one of the brush heads. Continuous same-direction rotation of the shaft causes the brush heads to counter-rotate about a common axis. Distal ends of the first set of bristles on the first brush head form a circular pattern and the distal ends of the second set of bristles on the second brush head form an elliptical pattern.
