Abstract: The frac plug device is a wedge type or ramp type frac plug that can seal at a setting position in a large diameter portion of the borehole. The thickness, taper angle, and dimensions of components for passing through the narrowest portion of the borehole during deployment no longer limit the radial expansion. The frac plug device includes a core cone, a segmented cone, a slip device, a segmented cap member, and a core cap member. A simplified setting action sets the high expansion of the slip device by the core cone and the segmented cone. The segmented cone and the segmented cap member increase expansion of the slip device, and the segmented cap member and the core cap member lock the slip device around the core cone in the final expansion configuration at the maximum radial expansion for large diameter portions of the borehole.

Abstract: A bioreactor includes a reservoir container for holding a liquid medium, a duct providing a flowpath in a generally vertical direction upward from the reservoir container, a plurality of fiber assemblies located within the duct, a top of which is higher than a top of the plurality of fiber assemblies, and a circulation system. The upper end of the duct comprises an overflow wall surrounded by a moat, a bottom of which is lower than a top of the overflow wall. The upper end of the duct and moat contact a pocket region that is bounded by a structure that is connected to the duct and that is isolated from fluid communication with an exterior of the pocket region. The liquid medium flows over the overflow wall within the pocket region, contacts gas in the pocket region, overflows into the moat and is removed therefrom by the circulation system.

Abstract: A bioreactor for culturing of cells is described. Screens suitable as a cell growth scaffold may comprise crossed fibers. Screens may be contained loosely in a screen holder, which in turn may be contained inside a manifold assembly. A lower manifold, screen holder and upper manifold may have identical or similar interior open cross-sections. Flow of liquid medium can occur upwardly through the array of screens, then flowing over a weir in the presence of an air pocket, and into a moat and a pump. The screen holder may have slots whose exterior-facing ligaments are rounded, and may have grooves whose interior-facing edges are rounded. These components may be located inside an incubator suitable to maintain desired environmental conditions and cleanliness.

Abstract: A vehicle engine compartment assembly includes an upper longitudinal beam and a front subframe disposed under the upper longitudinal beam. The vehicle engine compartment assembly further includes a middle longitudinal beam and a connecting supporting member. The middle longitudinal beam is disposed between the upper longitudinal beam and the front subframe. The connecting supporting member is connected to each of the middle longitudinal beam, the upper longitudinal beam and the front subframe. In the vehicle engine compartment assembly, the middle longitudinal beam is added between the upper longitudinal beam and the front subframe, and the upper longitudinal beam, the middle longitudinal beam and the front subframe are connected together to form a stable structure having a shape of “”. When the vehicle suffers collision at a high speed, the impact force is transferred through three load transfer paths to improve the energy absorption effect.

Abstract: A method of auction is disclosed. The method includes: detecting one or more auction prices from a plurality of second calculating devices within a pre-set time by a first calculating device; upon detection of at least one auction price, determining one of the plurality of second calculating devices as a successful bidder within the pre-set time; and repeating the foregoing steps until the item is sold or passed, wherein when the item is sold, the method further includes: giving a commission or a red envelope to each second calculating device that has been determined as a successful bidder within a corresponding pre-set time except the second calculating device to which the item is sold. The method enables a user to implement online item transaction through a second calculating device, thus lowering the threshold for a common user to participate in auction.
