  • Patent number: 7662017
    Abstract: A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a support surface in a lifting motion and roll end over end over end. The lift mechanism includes a lift arm pivotally mounted to a housing of the toy vehicle. A lift arm actuating motor is coupled to a lift arm drive screw that is in threaded engagement with a lift arm drive nut. A strut is coupled between the drive nut and the lift arm. In operation, the lift arm actuating motor drives the lift arm drive screw and causes the lift arm drive nut to drive the strut and move the lift arm into an extended position, causing the lift arm to engage a support surface to lift the toy vehicle. In the extended position, the toy vehicle is sufficiently rounded to permit the vehicle to roll end over end over end.

  • Patent number: 5512545
    Abstract: PDGF-B analogues are prepared in which an amino acid residue at a protease site is replaced with the corresponding amino acid residue from PDGF-A. The polypeptide is obtained at yields which are five to ten times greater than that for naturally occurring PDGF-B and retains the biological activity of the natural polypeptide.
