Abstract: A cordless appliance includes a blender having a base unit with a housing and an upwardly opening upper cavity. A drive connection is positioned within the upwardly opening upper cavity. The housing further includes a battery-receiving cavity that is configured to receive a removable battery. A motor is disposed within the housing of the base unit it is contemplated to be powered by the removable battery. A blender jar includes an upper collar in an interior cavity. A first lid assembly is configured to be coupled to the upper collar of the blender jar and includes a blade assembly and a drive connecting member. A second lid assembly includes a cap member removably received on an open aperture of the second lid assembly. The first and second lid assemblies are configured for limited rotation with respect to the blender jar for engagement of the same.

Abstract: A blade grinder that includes a base unit having a housing. The housing encloses a drive motor and defines a receiving cavity. A battery receiver is defined along a portion of the housing and a battery is removably coupled to the battery receiver. A blade implement is disposed within the receiving cavity, wherein the blade implement is configured to be driven by the drive motor. A bowl is positionable in an operably disposed condition within the receiving cavity. A lid is couplable to the housing to retain the bowl in the operably disposed condition within the receiving cavity.

Abstract: A vacuum cleaner assembly is provided that includes a body extending along an axis to a base connection end that includes a protrusion. A handle extends from the body opposite the base connection end. A dust collection portion includes a body connection end that includes a track with a lock passage extending perpendicularly from the track. The protrusion is located in the lock passage in a locked position and in the track in an unlocked position to selectively remove the dust collection portion from the body.

Abstract: Described herein is a method for removing coke deposits in radiant tubes of an olefin cracking furnace and removing accumulated spalled coke from one or more outlet elbows of the olefin cracking furnace without performing a cold shutdown of the furnace.

Abstract: A method and apparatus provides QoS shaping/provisioning scheme for a data communications switch, such as a DiffServ aware router or a 802.1Q aware bridge, in which distinct internal and outbound priority values are assigned to a packet based on flow properties associated with an inbound packet. The flow properties used to assign the internal and outbound priority values may include at least one value from a packet field that is not dedicated to defining QoS. The internal priority value provides a priority to the packet during processing in the switch. The outbound priority value is applied to the packet in lieu of the inbound priority value prior to transmitting the packet from the switch. The flow properties used to determine the internal and outbound priority values may include, for example, Layer 2, Layer 3, and Layer 4 information encoded in the packet.

Abstract: Lookup scheme in which a tuple representing a plurality of flow properties is parsed into multiple subtuples for application in recursive lookups. A first subtuple including a first subset of bits from the tuple is applied to the flow information database and returns a result including a nickname having a smaller bit count than the first subtuple. A second subtuple including a second subset of bits from the tuple and the nickname are combined and applied to the flow information database. The lookups continue until a result indicates that no recursion is required. The final lookup result includes flow information applicable to one or more of modifying, enqueuing or forwarding the packet. A truncated lookup capability enables common processing across a group of distinct flows having common flow properties.

Abstract: A method and apparatus for accomplishing source learning in a data switch of the type having a plurality of switching modules where each supports one or more external network devices and a backplane interconnecting the switching modules. Each switching module has logic resident thereon for performing distributed source learning, including configuring unknown source addresses “seen” in inbound packets and for notifying the other switching modules that such source addresses were “seen” on a port thereof. Address-port associations are thereby configured on the switch using distributed logic, i.e. without intervention by a centralized management entity. In regard to configuring destination addresses—when a destination address is unknown, packets are delivered over a multicast queue until the destination address is found. Once the destination address is found, a method of flow integrity is used to avoid out of order packet delivery when the device transitions from using a multicast flood queue to a unicast queue.

Abstract: A stage-implemented QoS shaping scheme is provided for a data communication switch. The stage-implemented QoS shaping scheme may be implemented by augmenting an existing packet forwarding logic. Inbound packets or other input signals enter the switch with inbound QoS or priority information. The inbound QoS information and packet header data are used by the switch to determine internal and outbound QoS information in stages. The first stage receives a key including addressing and other information and determines a QoS shaping index. In the second stage, the QoS shaping index is used to select QoS shaping maps, and the inbound QoS information is mapped to the QoS shaping maps to select internal and outbound QoS information.
