Abstract: An apparatus having a first panel and a second panel that may form part of a network enclosure. The first panel is connected to the second panel. A nut has a first portion and a second portion extending outwardly from the first portion. The second portion of the nut is trapped between the first panel and the second panel. There may also be a joining plate of a field replaceable unit fixable to the network enclosure by at least one bolt engaging the nut.

Abstract: A system includes a circuit board module having a device mounting section. The system further includes a small form factor transceiver and a form factor converter. The form factor converter is configured to concurrently connect to (i) the circuit board module and (ii) the small form factor transceiver. The form factor converter includes an exterior portion defining a large form factor (e.g., the standard X2 form factor) to fit within the device mounting section of the circuit board module when the form factor converter connects to the circuit board module, and an interior portion defining a small form factor (e.g., the standard SFP form factor) location to receive at least a portion of the small form factor transceiver when the form factor converter connects to the small form factor transceiver.

Abstract: An electronic equipment assembly includes a shelf having a front section configured to support a front set of circuit boards and a rear section configured to support a rear set of circuit boards. The electronic equipment assembly further includes a midplane disposed within the shelf between the front section and the rear section. The midplane is configured to directly connect to the front set of circuit boards and to the rear set of circuit boards. The electronic equipment assembly further includes a fan subsystem disposed within the shelf. The fan subsystem is configured to generate an air stream through the front and rear sections with air flow of the air stream being faster through the front section past the front set of circuit boards relative to the rear section past the rear set of circuit boards.

Abstract: Techniques for accommodating chassis tolerances use joiners which enable outer side panels for a front card cage to reference a front side of a midplane, and outer side panels for a rear card cage to reference a rear side of the midplane. The joiners couple the outer side panels together in a rigid but accommodating manner regardless of variations in midplane board thickness. Accordingly, both the front and rear card cages are capable of accurately and consistently referencing from the midplane sides. Not only do these techniques solve registration drawbacks which exist in conventional midplane installation approaches involving the bolting of midplanes to the middles of pre-constructed frames, these techniques further enable accurate direct connection of other components such as a power supply subsystem (e.g., to the midplane front side) and a fan assembly (e.g., to the midplane rear side) thus alleviating the need for burdensome cables.

Abstract: In a computerized device requiring a relatively large amount of power during operation (e.g., between approximately 10 kW to 15 kW) at a relatively large current (e.g., between approximately 200 and 300 amperes), an electrical conductor or power distribution assembly having a substantially flat, planar geometry electrically couples a power supply, via bus bars, to a midplane of the computerized device. The substantially flat planar geometry of the power distribution assembly minimizes conduction and radiation of electromagnetic interference (EMI) by the electrical conductor during operation of the computerized device.

Abstract: A heat sink apparatus includes a heat sink having a plurality of circuit board component contact portions and a plurality of fin portions extending from the contact portions. The circuit board component contact portions of the heat sink conform to a surface of the circuit board component when coupled to the circuit board component, thereby providing a thermal coupling between the fin portions of the heat sink and the associated circuit board component. The heat sink apparatus also includes a retainer, such as a double buckling beam retainer, that secures the heat sink to the circuit board component. The retainer causes the circuit board component contact portions of the heat sink conform to the surface of the circuit board component, thereby providing thermal contact between the heat sink and circuit board component contact portions and alleviating the need for a base portion associated with the heat sink, as in conventional mechanisms.

Abstract: The invention relates to a method of producing a thickened slimes fraction blended with a tailing fraction for delivery to a discharge or disposal point (38). The method includes the steps of forming a bed of tailings fraction on a de-watering screen (28) and delivering a thickened slimes fraction onto the bed of tailings fraction. The slimes fraction (30) is then allowed to de-water through the bed and the screen.

Abstract: A racket frame and throat unit is prepared by injection molding using a mold with a mold cavity defining the oval frame and the throat. The method includes first injecting a first quantity of a fiber-reinforced thermoplastic resin into a first injection port at an end of the mold cavity remote from the throat, and second injecting a second quantity of the fiber-reinforced thermoplastic resin into a second injection port in the throat region. The step of second injecting is commenced at a time after the step of first injecting is commenced, typically 1-2 seconds after the first step is commenced. The frame is solid, with a central solid body at a planar centerline of the frame, and two solid arms extending outwardly from the solid body at an angle to the planar centerline of the frame of from about 70 degrees to about 80 degrees, one arm above and one arm below the planar centerline of the frame. There is preferably an oval hoop at a distal end of each of the solid arms.

Abstract: An automatic system to precisely maintain bactericidal action in a reservoir of water equipped with a recirculation system, such as a swimming pool, decorative fountain, spa, cooling water reservoir or the like. The automatic system includes: a service loop which bypasses a portion of the recirculating water past sensors which measure the pH and oxygen reduction potential (ORP) of the water and in which acid and halogen are injected by a chemical feed unit; an electronics unit for determining the injection quantity of the acid and/or halogen needed to restore pH and ORP to stored set-points, and for controlling the chemical feed unit in response to the injection time determination; and an optional telecommunication unit for reporting process control status to a remote location and allowing modification of the process parameters, selection of operating modes, and performance of diagnostic tests from the remote location.
