  • Patent number: 6777227
    Abstract: A bioreactor or cell culture surface comprises a multiplicity of microwells appearing, upon enlargement in the range of 200 to 1000 magnifications, as a honeycomb structure consisting of a plurality of rows of irregular hexagons, each having a transverse x-axis, a longitudinal y-axis, and a z-axis which defines a height of each microwell. Co-parallel major bases define the directionality of anticipated cell growth, while pairs of equilateral minor bases define the x-axis width of each microwell. An arrow-like geometry is defined by the equilateral pairs of minor bases which also define an x-axis separation between opposing major bases of the hexagon to induce cell growth directionality. An acute angle exists between the members of the arrow-like pairs of minor bases, while an obtuse angle exists between contiguous major and minor bases.

  • Patent number: 6759134
    Abstract: A process for forming a metallic article having a black ornamental surface includes the steps of metallurgically providing an alloy containing between about 51 and 70 about percent by weight of titanium, between about 3 and about 17 percent by weight of niobium, and the balance of a metal selected from the group consisting of zirconium, tantalum, molybdenum, hafnium zirconium, chromium, and mixtures thereof. The alloy is then casted and/or metal worked into a workpiece having a desired geometry and surface texture. The workpiece thereof is then baked in a kiln or oven in a substantially air atmosphere of between about 450 and about 850 degrees C. for a period of between about one and about 29 minutes. Resultant of such baking, there is produced a durable black surface layer consisting substantially of an oxide of niobium which is adhered to the substrate of the workpiece which remains unoxidized.

  • Patent number: 6708717
    Abstract: A flushing system for air conditioning drainage pipes including a pipe assembly, a valve for selectively blocking the pass of the upstream drain line and a connection for a pressurized fluid supply. Each of the pipe assembly ends has a slidable tubular member cooperatively larger in diameter than said pipe assembly and drain line to snugly receive the ends of the pipe assembly. The tubular members are slid partially over the drain line ends and the ends of the pipe assembly. An alternate embodiment uses cooperating threads on the ends of the pipe assembly and one of the ends of the slidable tubular members. To flush the system with a fluid (liquid or gas), a user closes the valve assembly by rotating the ball valve member and applies the pressurized fluid to flush the system. Also, O-rings are used to enhance the sealing engagement in yet another embodiment.

  • Patent number: 6394319
    Abstract: A flexible liquid feeding assembly as an add-on device for use with liquid dispensing bottles is disclosed. The flexible liquid feeding assembly contains a flexible tube and a weight feeder for feeding liquid into a liquid dispenser of a liquid dispensing bottle. The flexible tube has a high degree of flexibility, and the weight feeder has a sufficient weight. Such structural features enable the weight feeder to move in the same direction of liquid's movement in the dispensing bottle. Therefore, the flexible liquid feeding assembly provides a continuous liquid supply regardless the bottle's orientations, even when the bottle is in an inverted position. Alternatively, a weight blocker can be used in conjunction with liquid feeding holes on the side of flexible tube. A liquid dispensing bottle containing a flexible liquid feeding assembly is also disclosed.
