Patent number: 5512480Abstract: The invention is a flow-through bioreactor for the retention and culture of cells in perfused media. The bioreactor is a generally rectangular vessel with inlet and outlet ports in the lid allowing for media flow along the longitudinal axis of the vessel. The inner surface of the bottom wall of the bioreactor has a plurality of generally rectangular grooves having a length, a depth, and a width. The grooves are positioned in the bottom wall such that their length is transverse to the longitudinal axis of the vessel, allowing media flow across the width of the grooves. Cells settle into the grooves, where they proliferate and differentiate, without entering the bulk flow of media through the vessel, thus avoiding loss of cells due to media flow. The preferred grooves have a width to depth ratio of about 1:1 or 2:1. The preferred width of the grooves is about 50 .mu.m to about 5,000 .mu.m, and the preferred depth is about 50 .mu.m to about 5,000 .mu.m.Type: GrantFiled: June 1, 1995Date of Patent: April 30, 1996Assignees: Baxter International Inc., Northwestern Univ.Inventors: Craig Sandstrom, E.

Patent number: 5510984Abstract: The enunciator system for an AGV includes a transmitter mounted on the AGV connected to an electrical control circuit having a plurality of individual switches operable to cause the transmitter to transmit a specific signal upon arrival of the AGV at predetermined locations along a circuitous route. Each location along the AGV route has identifier markings detectable by the AGV such that the AGV will stop for a predetermined period of time at each location as it travels along its route. If a switch for a specific location is actuated, the transmitter will transmit a signal to a receiver at that location which then triggers an audio or visual alarm at the location to alert a person at the location as to the arrival of an item on the AGV. After a predetermined period of time, the alarm will cease and the AGV will continue along its circuitous route.Type: GrantFiled: November 28, 1994Date of Patent: April 23, 1996Assignee: Board of Regents-Univ. of NebraskaInventors: Rodney S.

Patent number: 5466295Abstract: A plurality of magnetized elements form a continuous surface proximate to a waveguide opening, sufficient to satisfy electron cyclotron resonance plasma generation. With the elements similarly magnetized in a direction perpendicular to their central axis and parallel to the plane in which they are situated, a continuous resonance surface may be formed without the need for an externally applied magnetic field. Other magnetization orientations, such as perpendicular to the plane of the elements, may require an external magnetic field, such as that derived from solenoidal coils, but of a magnitude substantially reduced due to the combined field supplied by the elements.Type: GrantFiled: October 25, 1993Date of Patent: November 14, 1995Assignee: Board of Regents Acting for the Univ. of MichiganInventor: Ward D.
