    摘要: A network controller system including a plurality of network ports and a driver system that operates the network ports as a team. The team is operated to simulate a single logical device in one of several team modes, such as fault tolerance or load balancing modes, to enhance performance of communication of the computer in a network. The driver system periodically determines and updates the status of each of the network ports, where the status of each is based at least on whether at least one directed packet has been received and transferred to the driver system by a respective network port. If any one of the network ports has not received a directed packet within a predetermined time period, the driver system commands another network port to transmit a directed heartbeat packet to the network port that has not received a directed packet. The team may include a primary and one or more secondary ports. The primary port sends a directed packet to any secondary port that has not received a directed packet within the predetermined time period. One or more of the secondary ports may each send a directed heartbeat packet to the primary port if the primary port has not received a directed packet within the predetermined time period.

    摘要: An electronic structure, and associated method of formation, in which a plated metallic layer such as a copper layer, of a plated through hole (PTH) is adhesively coupled to holefill material distributed within the PTH. The holefill material includes a resin such as an epoxy and optionally includes a particulate component such as a copper powder. The adhesive coupling is accomplished by forming an adhesion promoter film on the plated metallic layer such that the adhesion promoter film is bonded to the resin. The adhesion promoter film may include a metallic oxide layer such as layer containing cupric oxide and cuprous oxide, which could be formed from bathing the PTH in a solution of sodium chlorite. Application of a reducing solution of dimethylamine borane to the cuprous oxide layer would convert some of the cuprous oxide to cupric oxide in the metallic oxide layer. Another possibility for an adhesion promoter film is an organometallic layer such as a layer that includes a chemical complex of metal and an organic corrosion inhibitor. Useful organic corrosion inhibitors for this purpose include triazoles, tetrazoles, and imidazoles. The organometallic layer could be formed from bathing the PTH in a bath of hydrogen peroxide, sulfuric acid, and an organic corrosion inhibitor.

    摘要: A hanger for hanging a product having a flat surface for display is provided in the form of a flat, flexible sheet having a plurality of bonding sections provided adjacent to opposite edges of the sheet which are adapted to be attached to the product. The flat, flexible sheet has a top section, a bottom section, two side sections and an intermediate section bounded by and coplanar with the top, bottom and size sections. Inside the intermediate section is provided a centrally located fold-up portion which is defined by a cut-line and a fold-line. The fold-up portion is rotatable about the fold-line between an initial position at which the fold-up portion is provided below the fold-line and a second position at which an upper portion of the fold-up portion is provided above the fold-line. The upper portion of the fold-up portion contains a member for supporting the hangar and the bottom section of the flat, flexible sheet has a gap provided therein which extends throughout the height of the bottom section to the cut-lines to enable easy access to a bottom edge surface of the fold-up portion.

    摘要: An improved method and apparatus is disclosed for turning an articulated self-propelled conveyor which is adapted either for conveying materials or for movement along the surface of the earth, including a plurality of segments pivotally joined to form an elongated housing. The housing has an upper and lower surface with jacks attached to the segments for selectively lifting or lowering the elongated housing. A conveying apparatus is mounting along the upper and lower surfaces and connected between the upper and lower surfaces. Transverse flights are mounted to the conveying apparatus such that when the jacks have elevated the elongated housing the conveying apparatus will move material along the upper surface of the elongated housing and when the jacks have lowered the elongated housing against the surface of the earth, the conveyor apparatus will move the elongated housing along the surface of the earth. The turning capability of the self-propelled conveyor is enhanced by tapering the surfaces of the transverse flights which are in contact with the earth in a manner so that when the housing turns the portion of the conveyor in the turn will tilt into the turn so that the vertical axis of the segments in the turn will be slanted toward the inside radius of the turn.

    摘要: A heavy cylinder having an axial flow passage is pumped down a rotary drill string to a position adjacent a drill bit to cause an in-seam horizontal drill to be guided in a downward direction. The cylinder can be removed with a latchable retrieval tool after the path of the borehole is sufficiently altered.
