Abstract: A signal information recorded on a recording layer formed on a phase-change type optical disk (20) is reproduced as a phase change. Laser light emitted from a laser light source (1) is collimated to a reference light by a lens (7). The reference light is divided by a beam splitter (2) into a first reference light (12) and a second reference light (13). The first reference light is directed through a condenser lens (3) to the recording layer of the optical disk (20). A reflection light from the recording layer is directed through the beam splitter (2) and a second condenser lens (7) to an optical detector (6). The second reference light (13) is passed through a phase difference plate (4), a reflection mirror (5), the phase difference plate (4), the beam splitter (2) and then through the second condenser lens (7) to the optical detector (6) as a phase shifted reference light. At an input end of the optical detector (6), the reflection light and the phase-shifted reference light are interfered with each other and the signal information having substantially no phase jitter is obtained at an output of the optical detector (6).

Patent CA-2121404-C (CA)
Inventor: BARANYAI LAWRENCE
IPC: H04Q3/52
Filed: 1994-04-15
Granted: 1998-07-14
Abstract: An upgrade arrangement wherein the switching functions of an in-service switch or cross-connect system are transferred or "re-homed" onto a new, larger capacity switch via the existing input and output ports of the original system. The re-homing can be performed without loss of service, even if the original system is operating at full-capacity. By exploiting the protection redundancy engineered into existing telecommunication switching systems, all of the signals being routed through the original switch are temporarily consolidated onto only one-half of the switching fabric normally required to accommodate such connectivity. This signal consolidation allows half of the original switch ports to be brought off-line (without a service disruption), and linked to the new, higher capacity switching fabric. The signals that had been consolidated within the original switching fabric are then re-routed onto the new switching fabric (via the linked ports), and the other half of the original switch ports are brought off-line and linked to the new switching fabric. The re-routed signals (still being switched in a consolidated format within the new switching fabric) are then redistributed (un-consolidated) among the linked ports and the new switching fabric so that a normal switching pattern is reestablished Re-homing the signals onto a single new switching fabric allows all connections to be managed from a single control point. In addition, the re-homing to the new switching fabric is operationally transparent (timing and protocols within the switching system are unaffected, and full non-blocking access is maintained), and all existing cabling to and from the original input and output ports remains intact and functioning. In a preferred embodiment of the invention, the input and output ports of the original switching fabric are linked to the new switching fabric via electro/optic interfaces, which replace the standard input and output circuits of the original system.

Title: Method for making uncreped throughdried tissue products without an open draw
Inventor: RUGOWSKI JAMES SIGWARD
IPC: D21F2/00
Filed: 1995-03-16
Granted: 2008-01-15
Abstract: A method for making uncreped throughdried tissues is disclosed in which the dried tissue sheet is fully supported by a fabric up to the reel. This method eliminates the open draw between the throughdryer and the reel and thereby eliminates sheet breaks normally associated with such open draws. In addition, the machine direction strength of the sheet can be reduced since the added strength is not needed to traverse the open draw normally present in current processes. Reducing the MD  strength in turn enables the production of more square, less stiff sheet, which improves the tactile properties of the product.
