Abstract: A catalyst system composition comprising a chromium compound supported on a silica-titania support, wherein said catalyst system has been reduced with carbon monoxide, and a cocatalyst selected from the group consisting of: i) alkyl lithium compounds; ii) dialkyl aluminum alkoxides in combination with at least one metal alkyl selected from the group constiting of alkyl zinc compounds, alkyl aluminum compounds, alkyl boron compounds, and mixture thereof and iii) mixtures thereof can be used to polymerize olefins to produce a low density polymer with a decreased melt index and/or high load melt index. This catalyst system also can be used with a Ziegler-Natta catalyst system to polymerize olefins. Polymerization processes using these catalyst system compositions are also provided. Polymers resulting from polymerization processes using the inventive catalyst and cocatalyst systems have a decreased high load melt index, decreased melt index, increased fluff bulk density, and are useful as components to make bi-modal molecular weight resins for film and/or blow molding applications.

Title: Automatic seamless vertical roaming between wlans wwans
Inventor: BRIDGELALL RAJ
IPC: H04L12/56
Filed: 2001-12-27
Abstract: A Mobile Station (MS) is able to vertically roam in either direction between  two different network, i.e. WWAN and WLAN. The MS is equipped with a dual mo de Radio for WWAN and WLAN transmissions. The WLAN Radio is linked to a WLAN Enterprise Gateway Controller (EGC) via a first air link and the WWAN Radio is linked to a WWAN Base Transceiver Station (BTS) via a second air link. The E GC is connected to a Mobile Switching Center (MSC) which is in turn connected t o the BTS. An outgoing VoIP call from the WLAN Radio to a remote party on the WWAN will transition or seamlessly switch over to a WWAN connection when the  MS detects packet error rates, frequent scale back or consistent signal degradation. Upon such conditions, the WLAN Radio requests the EGC to reques t an Explicit Call Transfer via the MSC to the MS integrated WWAN Radio portio n which automatically accepts the call based on referenced information stored in the user's subscriber identification module (SIM). Once the WWAN Radio is confirmed connected to the remote party on the WWAN, the WLAN Radio drops th e WLAN connection. An incoming call between the MS and a remote user via the WWAN will transition to the WLAN Radio when the MS enters WLAN coverage. The  MS issues an ECT to the WLAN. After user verification by the WLAN Radio and theEGC signals acceptance of the call, the WWAN Radio connection is dropped and the call is now established between the WLAN Radio and the remote party on the WWAN.

Inventor: RAUDSEPP REIN
IPC: C22B3/38
Filed: 2001-03-26
Abstract: An improved process for separating cobalt values from nickel values in an aqueous nickel and cobalt sulphate-containing solution in which the solution is contacted with a water-immiscible organic solution containing an organophosphorous acid in a cobalt extraction circuit. The process is particularly useful for aqueous solutions containing high total metals content and elevated cobalt concentrations, while avoiding the formation and precipitation of ammonium sulphate containing double salts during the solvent extraction of the cobalt. The improvement includes contacting a portion or all of the water-immiscible organic solution required for cobalt extraction with a nickel-containing ammoniacal solution to produce a nickel-loaded organic phase and a partially nickel-depleted raffinate. The nickel-loaded organic phase is then passed to the cobalt extraction circuit for selective cobalt extraction in which nickel is displaced from the organic phase by cobalt, to produce a cobalt-depleted, nickel-enriched, raffinate and a cobalt-loaded organic phase. Advantageously, the nickel-containing ammoniacal solution is generated by adjustment of the nickel-containing raffinate from the cobalt extraction circuit, by additions of ammonia, preferably as ammonium hydroxide, and ammonium sulphate.

IPC: G06F3/048
Filed: 2003-05-05
Abstract: A virtual address bar user interface control is presented. The virtual address bar includes a plurality of interactive segments, each segment corresponding to a predetermined filter for selecting content in a computer file system. Collectively, the interactive segments represent a virtual address for selecting content. Selecting an interactive segment in the virtual address bar causes those segments subsequent to the selected segment to be removed from the virtual address bar. A user may select a peer filter for a segment to replace that segment's current filter and removes those segments subsequent to the updated segment. The virtual address bar can be selectively configured to operate as a conventional address bar, and reconfigured to operate as a virtual address bar. Additional filter segments are added to the end of the existing filter segments. Those existing filter segments that conflict with the added segment are removed from the virtual address bar.
