  • Adjustable dual-blade dust filter using granular bed flow
    Patent number: 7727298
    Abstract: A dust filter has adjustable sub-blades between blades. By adjusting the blades distanced and the sub-blades' positions and angles, stagnation area of filtration material on the blades are removed. Furthermore, space in the dust filter is fully used. Thus, a filtering efficiency is improved.

  • Exercising mechanism having a selective coupling assembly
    Patent number: 5035419
    Abstract: An exerciser has a handlebar pivoted to a frame and a drive axle and a shaft supported between two plates. A drive gear is fixed on the drive axle. Two rings are rotatably provided on the shaft and are engagable with each other. A driven gear is provided on one of the rings. When the drive gear and the driven gear are engaged with each other, the lower end of the handlebar is driven to swing by a rotation of a cam which is fixed to the other ring so that the handlebar can optionally be caused to swing.
