  • Patent number: 7184157
    Abstract: A print job is preferably displayed using a visual job ticketing application. An operator is enabled to create multiple job tickets describing print parameters to be applied to the print job. Using the visual job ticketing application, the operator may select a previously created job ticket to be used to display and/or print the print job. Alterations made to the print job are automatically propagated across all associated print job tickets. When creating new print job tickets, the operator may choose to start with a blank job ticket, a default job ticket, the last active job ticket or any previously created job ticket.

  • Publication number: 20050274218
    Abstract: Transmissions in which the mechanical gear shift arrangements are replaced by electro-hydraulic operated shift mechanisms that have to be able to be neutralised positively to ensure a proper operation. An arrangement and method are provided to determine the position of the shift rail so a shift can be made only if the conditions are right. To prevent engagement of two shift members at the same time and consequent damage in case of electronic failure, mechanical safety features such as detents are included.

  • Publication number: 20050092115
    Abstract: A shift control method for an automated manual transmission is provided. The method includes the step of modulating the force applied to a shift collar, via a shift rod and/or shift fork for example, during the engagement of the shift collar and a selected gear. The method modulates the initial engagement force applied to the shift collar when the rotational speed differential between the collar and gear is being adjusted, before increasing the force again following modulation. This modulation of the force decelerates the shift collar during the rotational speed adjustment and does not accelerate the shift collar to complete the engagement until after the modulation. In this way, a less abrupt engagement of the gear may be achieved. The control method may improve the driving characteristics of the vehicle employing the transmission and may also improve the power transmission efficiency.

  • Publication number: 20050031262
    Abstract: A fresenel zoned microstructured optical fibre is described. The fibre is constructed of concentric zones, each zone being defined by discontinuities in the refractive index. The refractive index within each zone may either be constant or may vary, for example each zone being a section of a parabola or hyperbola. The fibre may be used as a lens, for example for coupling light between fibres with different core sizes.

  • Publication number: 20050002594
    Abstract: A compensator for compensating polarisation-mode dispersion, comprises a splitter (30) arranged to split light, according to the light's polarisation, between a first optical path and a second optical path; a combiner (40) arranged to combine light from the first optical path and the second optical path, and a monitor (15) for monitoring the light. An active wavelength-delay device (70) is provided in the first optical path and arranged such that components of the light travelling in the first optical path and having different wavelengths are subjected to different delays, the delays being selected according to an output from the monitor (15).

  • Patent number: 6839527
    Abstract: A print job is displayed as a sequence of pages. An operator is enabled to create artificial pages representing such elements as cover pages and preprinted sheets which are normally apart from the print job data file. The artificial pages are inserted into a display of the real pages defined by the print job data file or original document and are therefore displayed visually just as the other document pages are displayed. They can be manipulated just like other pages; that is, they can be moved, deleted, replaced and so on.

  • Publication number: 20040225886
    Abstract: A system and method for enforcing a usage control for a document, including: receiving an encrypted message, the encrypted message including a first key and a usage information authorization for the document, the encrypted message responsive to a second key to extract the first key and the usage information authorization; accepting an encrypted device datastream and securely decrypting the encrypted device datastream using the first key by a device, the device manager: generating a decrypted device datastream derived from the encrypted device datastream, transmitting the decrypted device datastream to the device without writing the decrypted device datastream to a user-accessible memory; and using the second key to access a datastore and to update a usage record for the document with the usage information authorization and a device status signal, the serializer providing the device manager with the print authorization signal when a device request is consistent with the usage record.

  • Patent number: 6587217
    Abstract: The present invention concerns a method, apparatus, and article of manufacture for managing print files associated with a job ticket describing a plurality of print files included in a print job. The print files are stored in a library within a server. When space usage in the library has exceeded a predetermined limit, print files are migrated from the library to a backup unit. For each file migrated from the first storage device to the second storage device, a stub file is generated which includes information on the migrated file. A computer is used to select a print file to include in the print job described in the job ticket. If the print file selected is stored in the backup unit and a stub file is stored in the library, then the server will access the stub file upon selection of the print file. The stub file in the library is replaced with the print file in the backup unit when the stub file is accessed.

  • Publication number: 20030093758
    Abstract: A standard document viewing application, such as Adobe Acrobat Exchange, Microsoft Word or others, is used with plug in enhancements to display a document to be printed and visual feedback cues associated with user selected print job parameters. The job originator then has all the advantages of the viewing application when ticketing the job, such as thumbnail drag-and-drop and other manipulations, zoom, multiple-page display, multiple documents open simultaneously, document content editing and adjustment, bookmarks and other document navigation aids. In addition, the job originator can use a familiar interface to view documents without having to learn a new application.

  • Patent number: 5875518
    Abstract: A castor comprises a fork (10) carrying an axle (11) which extends through an aperture in both limbs (12 and 13) and by which a single wheel comprising two discs (14 and 15) is mounted on the fork (10). A roller bearing (22) is mounted on the axle (11). Each disc, (14, 15) comprises a radially outwardly extending annular disc portion (23, 24) and a tubular portion (25, 26) which projects to one side of the respective disc portion (23, 24). The tubular portions (25 and 26) are snap-fitted together, one within the other, and together form the single wheel which has two rims (27 and 28). The roller bearing (22) is fitted into the bore of the tubular portion (26) whereby the single wheel is supported thereon for rotation. The tubular portion (26) provides a plain bearing support for the tubular portion (25) of the other disc (14). Relative angular movement between the discs (14 and 15) is possible because of that.
