Abstract: A filled structure characterized by the combination of high compressive and tensile strength to allow a high bending load includes a fiber reinforced resinous hollow structure having a tensile strength of at least 30,000 psi. The hollow structure has first and second ends, an inside surface forming a boundary which encloses a space, and an outside surface. At least a portion of the outside surface of one of the ends has a roughened portion sufficient to provide frictional resistance with the ground when the one end is driven into the ground. A hard core is disposed within the space enclosed by the hollow structure. The hard core has a density of at least 35 pounds per cubic foot and a compressive strength of at least 1500 psi. The hard core is formed from a mixture of particulate cementitious material and liquid.

Abstract: In this approach to implementing a wireless communication system, in band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). Selective diversity processing is implemented in the translators by providing for at least two spatially separated receive antennas and two receive path circuits in the up link direction. A diversity circuit is time synchronized to the downlink signal to provide for proper detection and selection of the appropriate signal to be forwarded to a centralized BTS. As a result, a separate diversity path need not be maintained for the remainder of each backhaul link, and radio frequency components such as a second upconverter, synthesizer and power amplifier associated with the range extender can be eliminated.

Abstract: A technique for mobility signaling between a Base Transceiver System (BTS) and Mobile Switching Center (MSC) in a mobile telecommunications system. The MSC is interconnected to a number of BTSs using one or more primary rate links using a protocol such as Integrated Digital Services Network (ISDN), including a number of bearer (B) channels for voice transmission and at least one data (D) channel for control function transmission. Standard call processing messages are utilized on the ISDN D channel to support basic telephone functions such as call origination, call termination, and call release as much as possible. However, an additional logical communication link is established over each ISDN D channel to accommodate mobility related messaging which may include messages such as hand-off and registration messaging needed to support mobile communications.

Abstract: A distributed processing architecture for a wireless communication system in which handover intelligence is distributed between the Base Station Subsystem (BSS), Base Station Controller (BSC) and Base Transceiver System (BTS). Mapping between air-interface traffic (Um) channels and Abis-interface traffic channel connections is dynamically assigned. This permits the BTS to manage information concerning active frequency channel assignments, individual channel measurement data, and intra-cell handover. The BTS therefore need only escalate the handover decision to the BSC level when the situation requires inter-cell handover.

Abstract: A wireless communication system basestation making use of a wideband, multichannel digital transceiver having incorporated therein a time division multiple-access (TDM) bus for providing digital samples of a plurality of wireless communication channels, wherein the time slot duration and frame rate of the TDM bus may be reconfigured. The invention allows various air interface standards, even those having different channel bandwidths, to be serviced by the same basestation, without having to install additional or different equipment, and by automatically redistributing signal processing resources, eliminating the need to reconfigure the basestation when different types of wireless signaling must be accommodated.

Abstract: A portable care facility includes at least one container defining a generally box-shaped configuration in a closed condition. The container is sized for transport and shipping and is constructed and arranged to be openable and expandable from the box-shaped configuration into a larger, operative configuration defining a space sufficient to conduct certain procedures therein. Tenting structure is provided in the container and is sized and configured to be supported over the space to define a ceiling over the space and to extend in at least one direction generally outwardly from the space to define a covered triage area.

Abstract: A display device and article carrier combination includes a body having front and rear walls, the walls being connected at side edges and bottom edges thereof thereby defining a pouch having a closed bottom, closed sides and an open top portion. An envelope structure is coupled to and extends generally adjacent to the body. The envelope structure has a front panel and a rear panel. Certain edges of the front panel and the rear panel are joined together so as to define a pocket having an opening in which an article may be inserted. At least one of the panels is transparent such that when disposed in the pocket, the article may be visible through the panel. Suspending structure is coupled to the body and/or the envelope structure and forms a loop such that the combination may be suspended from the neck of a user.

Abstract: A sprayable, foam-forming, phenolic resin composition having the combination of properties of:(i) a viscosity suitable for spraying,(ii) a cure rate suitable for spraying to prevent running or sagging of sprayed foam,(iii) which when suitably cured provides a foam having a high temperature resistance, and(iv) the cured foam produces substantially non-toxic fumes when burned. The sprayable, foam-forming, phenolic resin composition is made from a phenol-aldehyde resin; optionally a phenol compound; a catalyst for catalyzing a curing reaction of said phenol-aldehyde resin; and a gas-generating compound which generates a gas during said curing reaction of said phenol-aldehyde resin. The invention also provides a method for making a phenolic-resin foam layer and a sprayed phenolic-resin foam layer.

Abstract: Provided is a method and apparatus which decreases a liquor--to--wood ratio at the top of a continuous digester while increasing a liquor--to--wood ratio in the upstream pre-impregnation vessel. A substantially wood-chip free liquor portion is drawn from the top of the digester through a heater to the bottom of the pre-impregnation vessel through a return conduit. A stream is drawn off the return conduit, upstream of the heater, for transfer to the top of the vessel without mixing with wool chips.
