Title: Method for producing ethylene homopolymerizates and ethylene copolymerizates of a lower mass density
Inventor: LOHSE GERD
IPC: C08F10/02
Filed: 1999-06-26
Abstract: The invention pertains to a method for producing ethylene homopolymerizates and ethylene copolymerizates exhibiting a lower mass density of up to 0.930 g/cm3 and a melt index ranging from 0.15 to 25 g/10 min (2.16 kg; 463 K).  Said polymerizates exhibit an improved processing stability and improved availability in the installation at pressures greater than 1000 bar and at temperatures of up to 603 K.  The polymerizates are produced in tubular reactors in the presence of radical-forming initiators, oxygen thereunder and chain transfer agents, of which at least one comprises an aldehydic structure. According to the inventive method, chemokinetic characteristics of the reactive feed materials (thermal half-life periods, concentrations, dosing quantities) are coupled with fluidically relevant characteristics of the tubular reactor (flow rate) while taking the target product quality (melt index, flow figure) into consideration. This coupling is carried out such that the interfering secondary reactions, especially polar-inductive substitution effects, which can lead to the formation and the enrichment of organic hydroperoxides are reduced to a minimum and, as a result, extraordinarily stable processing conditions can be obtained.

Title: High mass-flow rate air purifier
Inventor: MORNEAULT STEPHEN G
IPC: A61L9/20
Filed: 2001-03-30
Abstract: An air purifier includes a high mass-flow rate air-mover and a low mass-flow rate ultra-violet radiation decontamination device. The decontamination device is mounted in spaced relation to the air-mover so as to space the inlet of the air-mover from the inlet of the decontamination device. In particular, the inlet of the decontamination device may be disposed oppositely to the inlet of the air-mover, relative to the outlet of the decontamination device, along a low mass-flow rate flow path of a low mass-flow rate air flow.  The low mass-flow rate air flow passes ambient air into the inlet of the decontamination device, through the decontamination device so as to pass for an operative dwell time into operative proximity to at least one UV emitter mounted in the decontamination device and so as to exit from the outlet of the air-mover to then be drawn into the inlet of the air-mover. The air-mover is spaced from the decontamination device so as to draw into the inlet of the air-mover a second air-flow of the ambient air. The second air flow flows along a second flow path which does not flow within the operative proximity to any UV emitter in the decontamination device.

Title: Printer or copier system having re-employable container for consumables and method for the employment of the container
Inventor: WINTER HANS
IPC: G06K19/00
Filed: 1999-09-28
Abstract: A method for improving the printing quality, particularly for electrographic color printing, is described for a printer or copier system (1). Print consumables, particularly toner (59), are monitored in container-exact fashion and substance-specific information are employed for the control of the printing process.   Toner expiration dates for the consumables are identified and noted early at the respective printing location. Maculature is thereby avoided. The consumable contained in the container (2) and the amount of consumable contained is thus stored in machine-readable fashion at the container (2). An information carrier (13, 30, 35, 38) is provided at the container for non-contacting transmission of data and energy from a data read and/or write station (11) to the container (2). A transponder (13) that is provided with an individual hardware identifier is proposed as information carrier. The hardware identifier can be employed as component part of codes for device control.   Further, the printer or copier system comprises a recycling concept for consumables containers, particularly for example electrographic devices. One and the same container (2) is thereby multiply employed; the current container content can be acquired container-individually at any time by machine. To that end, the containers (2) are provided with an information carrier (13, 30, 35, 38) that contains machine-readably encoded information about the current or more recently contained consumable (59) situated in the container (2). A module that can be electronically written and read in non-contacting fashion is proposed as information carrier, particularly a transponder (13). The data stored in the transponder can be supplied to other system components such as a filling station (3), a central computer (51) with a data bank and the printer or copier devices (1) in parallel via a data network.

Inventor: ELLINAS GEORGIOS
IPC: H04B10/20
Filed: 2000-03-27
Abstract: A system and method for automatically restoring a network which contains a node with a failed switch. Protection cycles are generated for the network to be restored and cyclegroups are generated from the protection cycles. Each node is provided with protection switches (105) which internally interconnect the input/output to connecting links via interconnecting protection fibers.  The selection of which internal protection fibers upon which to switch transmitted information onto allows the node to be configured to create merged cyclegroups. Thus if a failure in the central switch is detected, the transmitted information is diverted to a selected protection fiber corresponding to a merged cycle group so that the information can be automatically passed around the failed switch via the protection fibers. Each protection switch has associated mapping data which defines which protection fiber will be switched to based upon the input and output link for the transmission that is required to be sent through the node. The system and method applies to non-planar networks as well as planar networks.

Title: The copy protection of digital audio compact discs
Inventor: EDWARDS ROGER
IPC: G11B20/00
Filed: 2001-02-14
Abstract: The ability of a data reader, such as a CD-ROM drive, to access, extract, or otherwise read the data on a digital audio compact disc provides a problem for the music industry. A user can use his CD-ROM drive to read the data from an audio disc into a computer file, and then that data can be copied. To provide copy protection, errors are deliberately introduced into the data on a CD, but these errors are of a type which are generally transparent to an audio player but which will interfere with the reading of the audio data by a data reader. According to the standards, the data on a CD is encoded into frames by EFM (eight to fourteen modulation). Each frame has sync data, sub-code bits providing control and display symbols, data bits and parity bits, and includes 24 bytes of data, which is audio data for a CD-DA. The standard requires that 98 such frames are grouped into a sector. To provide copy protection, each sector is provided with a non-standard number of frames, for example, has 99 rather than 98 frames. Then the SO and S 1 sub-code synchronisation patterns are placed one frame later than they otherwise would be, but the data within each frame remains the same. An audio player would divide the 24 bytes of data from each frame of the sector into 4 byte samples and continue playing the disc, albeit with an inaccurate time display. Howewer, a data reader used to read audio data from the CD-DA to enable a copy to be made, would produce a copy having a degraded quality of sound.
