  • Patent number: 8056677
    Abstract: This lift system serves as a powered ladder having a small footprint. The system is divided into two subchasses with a mast fixedly attached to a first subchassis for support of a liftable platform which may carry a human operator. Maneuverability is accomplished by a virtual articulating joint between the two subchasses. The joint comprises hydraulic cylinders operating in conjunction with wheel struts to form a three-point support. Articulation enables the lift system to be adjusted on sloped or uneven terrain to maintain the mast in a vertical orientation. One use of the lift system is to carry a fruit picker into an orchard or vineyard and to position the picker to work efficiently. The lift system may carry a robot and may be controlled either locally or remotely.

  • Patent number: 3977984
    Abstract: Resin beads impregnated with magnetic powder, e.g. barium ferrite or .gamma.-iron oxide magnetically aligned and located discretely with respect to each other are formed by suspending the beads in a liquid while polymerizing the resin and subjecting the beads to an aligning magnetic field during a portion of the process of polymerization of the resin at which the resin viscosity is sufficient to permit rotation of the magnetic particles and yet sufficiently high to prevent lateral movement, and hence clumping of the magnetic particles, e.g. a molecular weight range of between 1,000 and 10,000 and a viscosity of between 5 and 50 poise.
