Title: Apparatus for stacking flat articles
Inventor: DE VLAAM HENK
IPC: B65H31/30
Filed: 1999-06-28
Abstract: An apparatus for stacking flat printed products, wherein a stack (22) is ejected from a stacking well (12) by means of an ejector (30), and a cover sheet (28) is pulled into the stacking well (12) as the ejector ejects the previously formed stack. The next stack (22) then comes to lie on this cover sheet (28).      Arranged on the ejector (30) is a support (38) having a driving pin (40) which points downward. In each case, a cover sheet (28) is pinned on to said driving pin (40) by means of a support plate (50) which can be lifted and on which the cover sheet is positioned. By changing the position of a stripping lever (46) after the stack (22) has been ejected, the cover sheet (28), which has been pulled into the stacking well (12), is stripped off the driving pin (40).

Patent CA-2287746-A1 (CA)
Inventor: KESSLER PETER B
IPC: G06F9/45
Filed: 1999-10-29
Abstract: Apparatus, methods, and computer program products are disclosed for determining how to compile a program at runtime. A bytecode instruction associated with the program that can be compiled in multiple ways is retrieved and compiled in a particular way, typically the default way. At runtime, a virtual machine determines whether another way of compiling the bytecode instruction is more desirable and, if so, the bytecode is then recompiled the other way. In some embodiments, the portion of the program that contains the bytecode instruction to be recompiled is placed in a queue with other instructions that are to be recompiled. The virtual machine may examine changing requirements of the program that have developed at the program's execution in which the requirements are derived from profile data on each of the multiple ways the program can be compiled. The bytecode instruction within the program may be recompiled in a more preferred way based upon the profile data.

Title: Automated diverter capable of sorting bulky articles
Inventor: BONNET HENRI
IPC: B65G47/76
Filed: 1998-08-16
Abstract: Provided is an improved sorter assembly (12) that is capable of directly receiving articles (17) from multiple upstream sources (14a, 14b) and directly sorting to multiple downstream destinations (16a-16d), and that can sort a wide variety of articles (17), including heavy, bulky articles (17).      The sorter assembly (12) includes a carrying conveyor (26) having a conveying surface (28) that carries the articles (17) being sorted. The carrying conveyor (26) carries articles (17) in a longitudinal direction between an upstream end (30) and a downstream end (32) of the carrying conveyor (26). The sorter assembly (12) also includes a diverter (40) that extends perpendicularly from and moves across the conveying surface (28) to define a plurality of diverting orientations (112, 115, 116, 118, 120, 122). While the articles are being conveyed by the carrying conveyor (26), the diverter (40) engages and directs the articles (17) at least partially laterally across the conveying surface (28) toward the articles' destinations (16a-16d). The diverter (40) pivots about an axis (42, 48) of rotation that is perpendicular to the conveying surface (28), and that axis of rotation (42, 48) can be moved laterllay across the conveying surface (28). The axis of rotation (42, 48) of the diverter (40) can also be moved to be proximate to or between the opposite ends (30, 32) of the diverter (40). The diverter (40) can also translate across the conveying surface (28). The ability to translate, rotate and move the axis (42, 48) of rotation allows a single diverter (40) to easily and efficiently divert from multiple upstream sources (14) to multiple downstream destinations (16).

Title: Method and apparatus for register mark identification
Inventor: PATEL MANOJKUMAR
IPC: G06V30/224
Filed: 1998-09-02
Abstract: The function of a Color Register Control system on a printing press is to maintain close registration between colors printed on a surface by various printing cylinders. The control acquires an image of a cluster of register marks (712) printed by various printing cylinders. The register mark is a geometrically unique mark. The mark cluster is acquired by the camera (708) and each mark pattern is identified by checking shape of individual marks. Resulting location of a mark is used to compute and correct registration errors. The image is analyzed to identify marks printed by various printing cylinders. Register error is determined by computing the lateral and circumferential distance between marks printed by a print cylinder and a master print cylinder. Any error detected in this process is corrected by activating correction motors, typically stepper motors, on print cylinders. The control utilizes a commercially available IBM-PC compatible computer (700).
Patent CA-2305237-A1 (CA)
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/02
Filed: 1998-10-15
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or foams of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.
