Abstract: A conference server system, for internal use in the public switched telephone network (PSTN), links to public data communication networks (e.g. the Internet) for distributing computer displayable data between participants in voice telephone conferences. The server system includes a computer sub-system for storing data generated by the participants and distributing the data in coordination with voice presentations of respective participants. Data so stored and distributed includes computer-displayable data. Other data handled by the computer subsystem represents commands and functional requests issued by participants which pertain to the handling of computer-displayable data and voice parameters of the conference. Conference participants, having separate and concurrent access to both the PSTN and the data network, receive and view computer-displayable data prepared by one of the participants in coordination with the respective voice conference. The conference server system connects to voice conference managementresources of the PSTN in a manner enabling the server system to control voice parameters of a voice conference in response to data requests received from participants (e.g. requests from hearing-impaired participants for enhanced audio service), as well as enabling the conference management resources to control functions performed in respect to distribution of displayable data in response to spoken requests uttered by the participants, when the telephone system contains appropriate speech recognition equipment. Telephone system conferences utilizing the present conference server system have the advantage of being usable to support voice-only and/or data-only participants (participants respectively linked to only the voice or data distribution parts of a conference session), as well as to provide conference service between exactly two participants which may be more effective than comparable services that the same two participants would obtain using a direct dial-up telephone connection for voice and a public data network connection completely isolated from the voice conference management resources of the PSTN to exchange data.

Abstract: A paper pulp refining, bleaching and brightening process wherein the pulp is compressed to about greater than 35 percent, and treated in one or more closed refiner vessels with a 3 1/2% hydrogen peroxide (H2O2) bleach liquor to obtain a 2% peroxide and pulp mixture in the refiner, while the pulp and bleach liquor mixture is subjected to above ambient temperature (about 195 degrees Fahrenheit) and pressure (about 35 pounds per square inch). The pulp and bleach liquor mixture is mixed and neutralized with sulfurous (H2SO3) acid water to reduce the pH from about 12.0 to about 5.5 pH, and to reduce the consistency of the mixture to about 8 percent. The pressure and temperature of the mixture is reduced to near ambient and the consistency of the mixture is reduced to about 4 percent, at which time the pulp mixture has improved brightness over prior revealed processes, with the concurrent reduction in the volumes of chemicals used for bleaching and brightening.

Title: Linear indexing apparatus with selective porting
Inventor: SHY PERRY C
IPC: E21B23/00
Filed: 1998-01-21
Abstract: A  Linear  indexing  tool  is  operably  supportable  on  a tubing string in a subterranean wellbore and has a tubular housing structure within which a tubular mandrel is coaxially and slidably disposed.  An indexing structure is operable by tubing pressure to sequentially drive the mandrel through a plurality  of  axial  travel  increments  in  response  to  a corresponding successive plurality of tubing pressure forces exerted  on  the  indexing  structure.    Pressure  diversion apparatus is operative to permit flow of pressurized fluid from within the housing structure to an external, pressure-actuatable device,  such as a packer, only after the mandrel has been driven through at  least  two of its  axial  travel increments.  Accordingly, the internal tubing pressure may be elevated to a test level thereof, thereby driving the mandrel through its first axial travel increment,  without actuating the external device.   A subsequent tubing pressure reduction and  re-elevation  may  then  be  used  to  index  the  mandrel through another axial  travel  stroke  to cause  the  internal tubing pressure  to  be  operably  diverted  to  the  external device.

Title: Production of bridged metallocene complexes and intermediates therefor
Inventor: MALCOLM ARCELIO J
IPC: C07F17/00
Filed: 1997-06-20
Abstract: Bridged metallocene compounds are produced by a process of promising commercial utility for plant-sized operations. One of the key steps of the process involves converting a deprotonated silicon-, germanium or tin-containing ligand into the metallocence. Preferably, and in accordance with an embodiment of the invention, this is accomplished to g reat advantage by adding a diamine adduct of a Group IV, V, or VI metal tetrahalide to a solution or slurry formed from a deprotonate d silicon-, germanium- or tin-containing ligand and an organic liquid medium so as to form a metallocene. The overall process of the in vention involves the direct conversion of benzoindanones to benzoindanols which, without isolation, are converted to benzoindenes. There upon the benzoindenes are bridged by deprotonating the benzoindenes with a strong base such as butyllithium and reacting the resultant deprotonated product with a suitable silicon-, germaniumor tin-containing bridging reactant such as dichlorodimethylsilane. The resultan t bridged product is deprotonated with a strong base such as butyllithium and reacted with a suitable Group IV, V, or VI metal-containing reactant such as ZrCl4 to provide a silicon-, germaniumor tin-bridged Group IV, V, or VI metal complex, such as a dihydrocarbylsilyl-br idged zirconocene complex.

Title: Transmission of digital and analog signals in the same band
Inventor: BRAND CHARLES
IPC: H04W16/24
Filed: 1997-07-01
Abstract: A combination of broadband program materials, such as TV, plus digital communications services of all types, are broadcast to a cell in the same frequency band, such as 27.5 to 28.5 GHz. The combination of all the transmitted channels have a combined bandwidth substantially exceeding the frequency band. At least some of the channels are transmitted with two diversity characteristics different from those of other channels. In one embodiment analog signals transmit the broadband services, preferably using wide deviation FM modulation, the FM channels filling the band. By choosing carrier frequencies selectively, between 5 and 9 T-1 digital channels can be broadcast in each FM channel when polarization is the same. Differing polarization of digital and FM signals in the same band can enable selection and detection of the desired one of a full spectrum of digital signals, or any one of the analog signals.
