  • Patent number: 6223513
    Abstract: An exemplary embodiment of the present invention is a flyer bow having a first surface and a second surface in opposition to the first surface. The first and second surfaces are joined to form an airfoil shape. A channel passes through the flyer bow between the first and second surface and a wire guide is disposed within the channel. There is at least one orifice through one of the first and second surface thereby establishing fluid communication between the channel and the ambient atmosphere.

  • Patent number: 6173420
    Abstract: A method and apparatus for configuring a software application on a cluster is provided. A configuration coordinator executing on a configuration manager communicates with one or more configuration slaves executing on a set of nodes that are operating as a cluster. The configuration coordinator sends messages to the one or more configuration slaves to initiate a configuration operation for a software application. Each configuration slave automatically performs a series of actions to configure the node on which it resides. When all the nodes complete the configuration operation for the software, the process is complete. While performing the series of actions, the configuration slaves generate logs that reflect their progress in performing the series of actions. If a problem occurs during performance of the series of actions, the configuration slave that encounters the problem indicates to the configuration coordinator that an error occurred.

  • Patent number: 5320049
    Abstract: A pedestal for supporting a table top or the like wherein the pedestal includes at least two C-shaped legs. There is a tubular base for receiving base portions of the C-shaped legs with the base construction including projecting arms in accordance with the desired positions of the base portions of the legs. Each base unit is in the form of a pair of adjacent parallel arms spaced apart for receiving a base portion of an associated C-shaped leg therebetween. Outer ends of the arms are connected together by an integral bight. The arms are also connected together by straps or plates on which the lower portions of the legs are seated. There is a glide assembly which includes a fastener which secures a leg to a respective base unit. The fastener has an enlarged externally threaded head on which a glide member is threadedly engaged for vertical adjustment. Upstanding portions of a pair of legs are connected together by a generally X-shaped connector.
