Extractive distillation processes whereby water-soluble extractive distillation (ED) solvents are regenerated and recovered employ improved operations of the extractive distillation column (EDC) so that polar hydrocarbons are recovered and purified from mixtures containing polar and less polar hydrocarbons and measurable amounts of hydrocarbons that are heavier than intended feedstock and / or polymers that are generated in the ED process. The improved process can effectively remove and recover the heavy hydrocarbons and / or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein.

System and method to extend the data carrying capacity of a hybrid fiber cable (HFC) network by adding wideband RF signal capability above 1 GHz, and replacing at least some CATV active devices such as amplifiers with a new type of Coax Domain Node (CDN) device that acts to segment the CATV cable portion of the HFC network into a series of smaller domains. The CDN generally filter RF signals from 5-865 MHz, while amplifying and passing RF signals over 1 GHz. Upstream capability is enhanced because the CDN intercept 5-42 MHz upstream signals from each domain and convert to 1 GHz+ signals. Downstream capability is also enhanced because the CDN can take efficiently encoded 1 GHz+ digital data, QAM modulate it, and locally inject into each domain without crosstalk between domains. The system pushes data management and downstream from the head end to the CDN, creating more throughput.

A method of washing fabric articles in a tunnel washer that includes moving the fabric articles from the intake of the washer to the discharge of the washer and through multiple modules or sectors. Liquid can be counter flowed in the washer interior along a flow path that is generally opposite the direction of travel of the fabric articles. A dual use zone includes multiple of the modules or sectors. In a dual use zone, a module or modules can be used to both wash and thereafter rinse the fabric articles. While counterflow rinsing, the flow rate can be maintained at a selected flow rate or flow pressure head. One or more booster pumps can optionally be employed to maintain constant counterflow rinsing flow rate or constant counterflow rinsing pressure head.

A scanning module within a non-AP station receives first scan parameter values for performing a first type of scan to obtain a first type of information, and receives second scan parameter values for performing a second type of scan to obtain a second type of information. From the first and second parameter values the scanning module determines combined scan parameter values that satisfy scan requirements for both types of scans. The combined scan parameter values are used to control a sequence of combined scans. A combined scan yields both the first and second type of information. In one example, an IEEE 802.11(n) non-AP station receives 20 / 40 coexistence scan parameters. The 20 / 40 parameters and locally-generated background scan parameters are used to determine parameters for performing combined background and 20 / 40 scans. Reducing the number of scans using combined scans has advantages including increasing data throughput, freeing processing resources, and reducing power consumption.

After the moisture is removed from the particles, a hinge door is opened and a drive motor turns the first filter and flightings for particle removal. An alignment ring is attached to outer edges of the lower end of said flights in order to maintain a clearance of at least ¼ inch between the outer edges and the second filter element.

For LTE cellular data and Wi-Fi P2P technology coexistence scenario, a user equipment can generate in-device coexistence (IDC) indication message to the base station for DRX-based IDC solution. LTE data scheduling is described by a set of DRX parameters, while Wi-Fi P2P data scheduling is described by Opportunistic Power Saving (OppoPS) and Notification of Absence (NoA) parameters. When generating the IDC indication message for Wi-Fi P2P group client (GC), the DRX parameters must be selected carefully to maximize efficiency. Even though Wi-Fi shares less time, with proper time alignment, its coexistence performance could be better. For Wi-Fi P2P group owner (GO) with IDC TDM scheduling constraints, OppoPS and NoA should be aligned with DRX parameters to achieve best performance.
