Abstract: Herbicidal compositions are described containing either 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone (2,4-DC) or 2-(2,5-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone (2,5-DC). Compositions containing 2,4-DC or 2,5-DC and a second herbicide are also disclosed, where the combination does not contain both 2,4-DC and 2,5-DC. Methods of using the same compositions are also described.

Abstract: An apparatus for enabling communication between components in a network device includes a network processor providing data signals based on a PLx format; a multiport I/O controller having an IX bus interface and a plurality of MAC layer interfaces; and a bridge for bi-directionally converting the streaming data from the network processor to the I/O controller.

Abstract: A data structure for linking or chaining at least two 32 bit words or control markers that are inserted into a packet before the header of the packet that is also positioned at the front of a flow of packets that is being processed by a network processor in a network device. There are at least two types of control markers, primary and cluster. A reserved single bit field in the control marker indicates if multiple control markers are included and chained together in the packet ahead of the header and if the control marker is not a primary control marker, another three bit field indicates the type of that particular control marker, such as a cluster control marker.

Abstract: A data structure represented by a single 32 bit word or “cluster control marker” that is inserted ahead of a header of a packet at the front of a flow of packets from a cluster that is being processed by a network processor in a network device. The cluster control marker includes the results of calculations that have been accelerated through the use of hardware (ASICs) to perform certain tasks in advance for the network processor. The data structure includes the results of Word Type, MAC destination address and Cluster MAC address match, IP destination address and Cluster IP address match, Protocol Type and Destination Port indication, Cluster Hash Calculation value, and fragmentation indication.

Abstract: A data structure represented by a single 32 bit word or “primary control marker” that is inserted ahead of a header of a packet at the front of a flow of packets that is being processed by a network processor in a network device. The primary control marker includes the results of calculations that have been accelerated through the use of hardware (ASICs) to perform certain tasks in advance for the network processor. Because the insertion of in-band information has an impact on packet stream throughput, both the location of the insertion in the packet header and the type of results that are included in the primary control marker have an effect on the overall performance of the network processor, The data structure includes the results of IP header checksum verification, MAC level filtering and classification, VLAN indication, Flow Hash Index Calculation and Channel Identification.

Abstract: A bridge for converting a relatively high speed communication interfaces provided by a network processor into another type of relatively high speed interface that is supported by an I/O card in a network device. A proprietary high speed communication interface can be a first-in-first-out (FIFO) streaming data interface. The other type of high speed interface supported by an I/O card can be PL3, PL4, SPI 3, SPI 4, and the like. The network devices can include, routers, switches, firewalls, gateways, and the like. The bridge can be configured as an application specific integrated circuit (ASIC).

Abstract: Methods, apparatus and systems are directed to managing network traffic using a variable length Cyclical Redundancy Check (CRC) index to hash an address header. The invention copies an address header of a data packet to a CRC generator. A CRC index is determined based, in part, on the address header. A subset of bits is determined from the CRC index based, in part, on a predetermined bit mask. The address header and the data payload are then combined with the subset of bits from the CRC index. The modified data packet is subsequently forwarded over a network. In one embodiment, the invention is implemented on a hardware circuit residing on a traffic device.

Abstract: Telecommunications within networks are greatly facilitated by a modular telecommunication jack having LEDs and circuit board magnetics as an integral part. The modular jack of this invention can be easily surface mounted on a mother board. This invention also discloses a method of making su ch modular jacks.

Abstract: A discrete material washing apparatus comprises a structure mounting an elongate trough having an inlet and an outlet. A dished tray is mounted on the structure and shaped to feed into the inlet. The tray is to receive disposal of a cementitious mixture therein. A cylindrical screen has a net surface. The screen extends substantially along the length of the trough and is adapted for rotation. Water spray is provided to play on any mixture disposed onto the tray and passed through the inlet into the interior of the screen for size classification with smaller particles able to pass through the mesh of the screen surface into the trough and larger particles remaining in the screen. A first mechanism is provided to remove the smaller particles from the trough, and a second mechanism is provided to remove the larger particles from the interior of the screen through the outlet of the trough. A weir is provided in at least one longitudinal side of the trough for removal of the cementitious water therefrom.
