  • Publication number: 20090293418
    Abstract: A tensioner for tensioning foundation bolts generally used in securing large utility towers is provided. The tensioner generally comprises a hollow outer body through which the foundation bolt can extend. The lower end of the body, which is adapted to abut onto the foundation surface from which the bolt extends, is provided with an opening allowing access to a foundation nut threaded onto the foundation bolt. The upper end of the outer body slidingly receives therein an inner body with which it defines an annular hydraulic piston, the inner body being configured with a seat portion for receiving and engaging a split nut mounted to the foundation bolt. Upon providing hydraulic fluid to the tensioner, the hydraulic piston urges the split nut, engaged to the foundation bolt, upwardly, thereby tensioning the foundation bolt. The load in the bolt is then maintained by threading down the foundation nut until it abuts onto the foundation surface.

  • Patent number: 7604825
    Abstract: A process for making cheese comprising the steps: starting with a mil,m composition that has a milk fat content of more than 0.3%, adding a gum preparation to the milk, adding a starter to the milk to form a cheese milk, coagulating the cheese milk, cutting the coagulum to separate curd and whey, draining whey from the curd, and shaping and cooling the curd. The difference over the prior art is the addition of gum to the milk before the starter is added.

  • Patent number: 7496060
    Abstract: A method (300) of extending battery life in a communication device having a plurality of receivers includes receiving information with a primary receiver that is configured to operate on a first network (303) and controlling a secondary receiver that is configured to operate on a second network that is independent from the first network in accordance with the information obtained with the primary receiver. A corresponding communication device (201) includes: a primary receiver (221) configured to operate on a first network (203); a secondary receiver (227, 233) configured and arranged to operate as a short range receiver with an access point (205, 207) that is independent of the first network; and a controller (225, 231, 237) that is configured to control the secondary receiver in accordance with information obtained from the primary receiver.

  • Patent number: 7441761
    Abstract: An extension fixture for combining the clamping capacity of a first and a second bar I-beam cross section bar clamp. The first and second bar clamps each have a fixed jaw, a movable jaw, and a primary bar. The movable jaw of each bar clamp has a clamping means configured to provide a clamping force in the direction of the fixed jaw. To use the bar clamps with the extension fixture, the movable jaw is removed from the first bar clamp, and the movable jaw orientation on the second bar clamp is reversed so that the clamping means is then configured to provide a clamping force away form the second fixed jaw. The first and second primary bars are then inserted into the extension fixture, and pinned and clamped in position. The assembly then forms a combined capacity bar clamp.

  • Publication number: 20080045091
    Abstract: A latching mechanism for joining separable insulated connectors employs a plurality of finger contacts to create an interference fit with an electrode probe of an elbow connector. The electrode probe enters a cylindrical grouping of the plurality of finger contacts and a projection causes an interference fit between the finger contacts and the electrode probe. The finger contacts latch the connectors together and require a removal force greater than the latching force required to latch the connectors. The latching mechanism provides a multi-point current path between an elbow connector and a power transmission or distribution apparatus and provides operator feedback to indicate the latching of the mechanism.

  • Publication number: 20080017431
    Abstract: A straddle-type personal snow vehicle includes a body frame, an engine, a front support and a rear track drive mechanism that is driven by the engine. The front support may be a front suspension that supports at least one front ski. The rear track drive mechanism may be supported by a rear suspension that may include multiple linkage members. In one arrangement, the track drive mechanism includes a drive wheel and at least a first support wheel. An axis of rotation of the first support wheel is positioned forward of an axis of rotation of the drive wheel. In one arrangement, the at least one front ski is coupled to the front suspension by a tool-less attachment mechanism.

  • Publication number: 20070287313
    Abstract: An electrical device includes a body, an electrical contact having a first end for electrically coupling to an electrical apparatus and a second end within the body, and a conductor electrically coupled to the second end of the electrical contact. The electrical device also includes an access region defining a cavity and a surge arrester that electrically couples to the conductor through the access region. The cavity provides access to an interior of the electrical device. The access region may include an insulating projection extending from an insulating body of the electrical device and a conductive cover surrounding the insulating projection. The insulating projection defines the cavity. The conductive cover is electrically isolated relative to a conductive shell that surrounds the insulating body.

  • Patent number: 7295813
    Abstract: A method for reducing current drain in a communication device includes a first step of detecting interference including intermodulation and crossmodulation products. A next step includes determining a frequency offset of the interference with reference to the operating receiver band. A next step includes measuring a power level of the interference. A next step includes calculating a receiver linearity required to achieve a desired signal-to-interference ratio. A next step includes adjusting the receiver linearity in order to achieve the desired signal-to-interference ratio. Optionally, the receiver dynamic range can be adjusted to suit the reduced signal swing due to the reduced linearity.

  • Patent number: 7283533
    Abstract: A method for directly converting packet-based voice data of two non-compatible formats, (e.g., VoIP and VOATM), is described. A VoIP call agent sets a connection between a VoIP edge gateway and an interworking unit (IWU). The IWU allows the VoATM network to appear as a TDM network to the VoIP call agent. The VoIP call agent selects a virtual trunk group and channel identification code through the interworking unit and transmits the selection to a VoATM call agent. The IWU allows the VoIP network to appear as a TDM network to the VoATM call agent such that the VoATM call agent establishes a connection between the virtual trunk group and a VoATM network device. The IWU allows the VoATM network to appear as a TDM network to the VoIP call agent such that the VoIP call agent establishes a connection between the virtual trunk group and a VoIP network device.
