  • Patent number: 8003378
    Abstract: A bioreactor for cultivating living cells in a liquid medium. In one embodiment of the present invention, the bioreactor includes a first substrate having a first surface, an opposite second surface and edges. The bioreactor further includes a second substrate having a first surface and an opposite second surface, defining a cavity with a bottom surface, where the bottom surface is located therebetween the first surface and the second surface. The first surface of the first substrate is received by the second surface of the second substrate to cover the cavity so as to form a channel for receiving cells and a liquid medium. In forming the bioreactor, the channel is sized to allow the growth of a layer of cells on a biocompatible coating layer and a flow of liquid in the channel. The flow of liquid is controlled so as to provide a known shear force to the layer of cells. The flow of liquid can be further controlled so as to provide an environment that simulates a vascular space in the channel.

  • Publication number: 20060166354
    Abstract: A bioreactor for cultivating living cells in a liquid medium. In one embodiment of the present invention, the bioreactor has a first substrate having a first surface and an opposite second surface, defining a chamber therebetween for receiving the cells and the liquid medium. The bioreactor further has a barrier dividing the chamber into a first subchamber and a second subchamber, wherein the barrier has a porosity to allow the first subchamber and the second subchamber in fluid communication and allow at least one predetermined type of cells to permeate between the first subchamber and the second subchamber.

  • Publication number: 20060099705
    Abstract: A bioreactor (200) for cultivating living cells in a liquid medium. In one embodiment, the bioreactor (200) has a substrate (230) having a first surface and an opposite second surface, defining a channel (202) therein, and a plurality of chambers (204) formed in the substrate, wherein each of the plurality of chambers (204) is adapted for receiving cells in a liquid medium and formed with an open end (262), an opposite closed end (264) and side walls, the open end (262) and the closed end (264) defining a depth, d, therebetween for the corresponding chamber (206), the sidewalls defining a width, w, therebetween for the corresponding chamber (206). As such formed, each chamber (206) is in fluid communication with the channel (202) through the open end of the chamber (206), and at least two of the plurality of chambers (206) have depths or widths the same or different form each other.

  • Patent number: 4568236
    Abstract: A tractor drawn lift bed highway trailer for transporting high tonnage loads over the highway, utilizing pallet frame units adapted to be picked up or dropped off quickly without the need for additional equipment or personnel. The trailer has a relatively light, strong main frame; a lift bed adapted to be elevated from lowered loading position forwardly and upwardly into engagement with the gooseneck for additional rigidity during transport; improved protection for the load and the tractor in event of an emergency stop; and improved cornering characteristics.

  • Patent number: 4050709
    Abstract: A lift bed highway trailer adapted to be coupled to a tractor to transport heavy loads through use of pallet frame units that can be quickly picked up and discharged at any point, wherein provision is made in the trailer gooseneck structure for safely dissipating the kinetic energy of the pallet frame unit through resistance of friction and gravity in event of an emergency stop.
