  • Patent number: 6604886
    Abstract: In a preferred embodiment, a light weight telescope assembly for bicycles that is readily adjustable by riders in the field and that provides smooth action of the suspension system. This telescope assembly contains roller bearings to reduce stiction and prevent torsional losses. The adjustment mechanism includes an adjustable outer race shim composed of two oppositely tapered races moving longitudinally in relation to each other, thereby causing their combined thickness to expand or contract thus allowing the bearing pre-load to be adjustable. Integral with this adjustable pre-load mechanism is a bayonet-style collar whose design enables bearing pre-load adjustment from a position that is readily accessible by consumers. In addition, this collar enables greater geometric latitude on the shape of the inner tube, thereby enabling significant strengthening of the telescoping assembly using light weight materials and lower cost manufacturing processes that hitherto have been unachievable.

  • Publication number: 20030085128
    Abstract: This invention relates to a flexible and conformable apparatus for the purpose of electrostatic removal of very fine particulate from non-conductive fluids. This apparatus is physically conformable and adaptable to existing mechanisms without need for additional separate containment. The two charging electrodes are similarly flexible and conformable. They are housed in separate chambers and wired to a power supply providing positive and negative high voltage. The electrodes impart positive and negative charges to particulate flowing past. The mixing apparatus is connected to the charging apparatus via a turbulence-initiating connector and receives the fluid carrying the charged particles enabling the oppositely charged particles to agglomerate. A downstream porous collection filter connected to the mixing apparatus collects the agglomerated particulate matter.
