A card hold down assembly for retaining one or more expansion cards within the chassis of an electronic device such as a computer system, server, photocopier, facsimile machine, printer, or the like is described. The card hold down assembly is comprised of a retainer that engages the mounting bracket securing tab of an expansion card received in the chassis to at least partially restrain the tab for securing said expansion card in the chassis.

A mounting mechanism for multiple computer storage drives mounts at least one drive so that it may be swung out for easy access to the drive and to its cable connectors. The mechanism comprises a drive cage mounting bracket, a hinge, and appropriately adapted chassis, so that the mounting bracket is hingeably connected to the chassis to swing open for access and to swing closed for operation. The bracket is adapted so that, when in the open position, the cable connector of at least one mounted drive is distal from the hinge and chassis and thus easily accessible. A preferred embodiment provides for releaseably locking the bracket in the closed position. Furthermore, the bracket preferably mounts a hard drive so that it is suspended within the airspace above the computer motherboard for easier cooling.

An apparatus, method and system for the casting of thin strips or strips of metal upon a moving chill block that includes an electromagnet located so that molten metal poured from a reservoir onto the chill block passes into the magnetic field produced by the electromagnet. The electromagnet produces a force on the molten metal on said chill block in the direction toward said chill block in order to enhance thermal contact between the molten metal and the chill block.

Casting molten metal using a segmented roll for casting continuous metal strip. A strip caster (10) for producing a continuous strip (18) includes a tundish for containing a melt and a pair of horizontally disposed water cooled composite casting rolls (84). The casting rolls are juxtaposed relative to one another for forming a pouring basin (16) for receiving molten metal. The composite rolls are formed from a plurality of annular segments (45). Each segment preferably includes at least a pair of coolant openings (34) and means for aligning the coolant openings, such as a pair of alignment openings (26). The segments are axially aligned and structurally connected by a pair of connecting rods (42) extending completely across the width of the roll through the alignment openings and through appropriate end plates (96). Each roll includes a load supporting spindle (86) with each end of the roll sealed by a rotary seal (88). Coolant water is supplied to the composite casting roll by a flexible conduit (90) and heated water is removed through a flexible conduit (92).

A strip caster (10) for producing a continuous strip (24) includes a tundish (12) for containing a melt (14), a pair of horizontally disposed water cooled casting rolls (22) and devices (29) for electrostatically coating the outer peripheral chill surfaces (44) of the casting rolls with a powder flux material (56). The casting rolls are juxtaposed relative to one another for forming a pouting basin (18) for receiving the melt through a teeming tube (16) thereby establishing a meniscus (20) between the rolls for forming the strip. The melt is protected from the outside air by a non-oxidizing gas passed through a supply line (28) to a sealing chamber (26). A preferred flux is boron oxide having a melting point of about 550.degree. C. The flux coating enhances wetting of the steel melt to the casting roll and dissolves any metal oxide formed on the roll.
摘要:
Strip casting apparatus including a molten-metal-holding container and a nozzle to deposit molten metal onto a moving chill drum to directly cast continuous metallic strip. The nozzle body includes a slot bounded between a back and a front lip. The slot width exceeds about 20 times the gap distance between the nozzle and the chill drum surface. Preferably, the slot width exceeds 0.5 inch. This method of strip casting minimizes pressure drop, insuring better metal-to-chill-drum contact which promotes heat transfer and results in a better quality metallic strip.

A performance engine selects note patterns from a pattern style containing a plurality of note patterns. The note patterns are categorized by embellishment type and by ranges of playback levels. In addition, a beat pattern is specified for each note pattern, indicating the chord rhythm with which the style can be used. The beat pattern is a bit array, with bits corresponding to every beat of one or more contiguous measures. In response to selection of a particular embellishment type and playback level, the performance engine selects a note pattern that meets the following qualifications: (a) it is of the selected embellishment type; (b) its designated range of playback levels includes the selected playback level; and (c) its beat pattern indicates that it can accommodate chord changes at the beats at which such changes occur in the currently selected chord progression. If there are no qualifying note patterns, these conditions are gradually relaxed until at least one of the note patterns qualifies.

An audio application programming interface (API) enables an audio processing graph to be modified during processing. If they are received while the audio graph is playing or paused, graph modifying commands may be inserted into either an asynchronous command queue or a deferred command queue. The audio API may also include a clock manager for synchronizing clocks from a number of different connected audio rendering devices, applications, processors, functions, operations, modules, or other resources. The clock manager may provide an interface that enables a number of control groups to be defined. Each such control group may include a master clock, a slave clock, and a control.
摘要:
An apparatus and method for regulating the gap between a casting nozzle and a casting wheel in which the gap between the casting nozzle and the casting wheel is monitored by means of at least one sensing element protruding from the face of the casting nozzle. The sensing element is preferably connected to a voltage source and the casting wheel grounded. When the sensing element contacts the casting wheel, an electric circuit is completed. The completion of the circuit can be registered by an indicator, and the presence or absence of a completed circuit indicates the relative position of the casting nozzle to the casting wheel. The relative positions of the casting nozzle and casting wheel can thereby be selectively adjusted to continually maintain a predetermined distance between their adjacent surfaces.
