Title: A code division multiplex satellite broadcasting system
Inventor: WEERACKODY VIJITHA
IPC: H04N7/20
Filed: 1999-11-18
Abstract: A CDM satellite transmission system that broadcasts programming content, such as audio or video information, using two geo-synchronous satellites and a plurality of terrestrial repeaters based on Code Division Multiple Access (CDMA) technology is disclosed. A plurality of programming channels is multiplexed onto a carrier frequency using Code Division Multiple Access (CDMA) technology. A  delayed version of the signal is transmitted with the on-time version of the programming content to accommodate uninterrupted reception in the event of a blockage. The on-time and delayed version of each information channel is transmitted by each of the satellites and repeaters, providing additional diversity gains. Thus, the satellites and terrestrial repeaters occupy the entire available bandwidth. CDM transmissions are used where the pseudo-noise sequences are the same, or linear translates of one another. The terrestrial repeaters have a direct line of sight to at least one satellite and repeat the transmission of only one satellite.

Title: Lead formation in undulated coils for dynamo-electric machine stator
Inventor: BONNACORSI ANDREA
IPC: H02K15/04
Filed: 2000-04-13
Abstract: Apparatus and methods for reducing the likelihood of damage to wire leads of undulated coils for dynamo-electric machine stators are provided. The invention provides a rotating winding head equipped with a coil former that has a wire gripper and an initial wire lead slot. The gripper retains the initial wire lead. The slot permits the initial wire lead to be fed to the gripper from a stationary wire source. The gripper maintains the initial wire lead in a predetermined plane of the coil and can secure the initial wire lead in the plane in which the final lead wire will eventually be disposed. The gripper also rotates the initial wire lead into radial alignment with a lobe of the undulated coil. Once installed in a stator, the initial and final wire leads can both be disposed along the outer radius of the coil and are thus protected from interference with a rotor that is destined to rotate within the stator.

Title: Spray application of an additive composition to sheet materials
Inventor: CESARETTI RICHARD SCOTT
IPC: C09K3/30
Filed: 1998-10-09
Abstract: The present invention is directed to methods for the spray application of additive compositions containing additive materials in the manufacture of sheet material products, such as paper products, textile products, and flexible sheet products by using compressed fluids, such as carbon dioxide and ethane as a spraying medium. Additive compositions with high viscosity and which are substantially free of water and/or volatile solvent can be applied to sheet materials. Water-home additive compositions with reduced water content can also be applied to sheet materials. One preferred spray method uses a decompressive spray of the compressed fluid which produces a uniform spray pattern and a narrow droplet size distribution that can improve application efficiency and quality when additive compositions are applied during the spraying step to rapidly conveyed sheet materials.

Patent CA-2312492-A1 (CA)
Title: Multi-protocol unified file-locking
Inventor: BORR ANDREA
IPC: G06F17/30
Filed: 1998-11-30
Abstract: The invention provides a method and system for correct interoperation of multiple diverse file server or file locking protocols, using a uniform multi-protocol lock management system. A file server determines, before allowing any client device to access data or to obtain a lock, whether that would be inconsistent with existing locks, regardless of originating client device or originating protocol for those existing Locks. A first protocol enforces mandatory file-open and file-locking together with an opportunistic file-locking technique, while a second protocol lacks file-open semantics and provides only for advisory byte-range and file locking. Enforcing file-locking protects file data against corruption by NFS client devices. A CIFS client device, upon opening a file, can obtain an "oplock" (an opportunistic lock). When a client device issues a non-CIFS protocol request for the oplocked file, the file server sends an oplock-break message to the CIFS client device, giving the CIFS client device the opportunity to flush any cached write operations and possibly close the file. Allowing NFS and NLM requests to break oplocks ensures that file data remains available to NFS client devices simultaneously with protecting integrity of that file data. A CIFS client device can obtain a "change-monitoring" lock for a directory in the file system, so as to be notified by the file server whenever there is a change to that directory. The file server notes changes to the directory by both CIFS and non-CIFS client devices, and notifies those CIFS client devices with "change-monitoring" locks of those changes.
