Patent CA-2211529-A1 (CA)
Title: Method and device for the repair and/or touch-up of small surface flaws in a press plate or an endlessband for surface-embossing of plastic-coated wooden or laminated panels
Inventor: LETTMANN HEINZ-PETER
IPC: B29C59/02
Filed: 1996-11-11
Abstract: A process and device are disclosed for retouching and/or repairing small superficial damages of a large-format press plate or endless belt made of sheet metal, in particular sheet steel, having a structured metal coating and a hard chromium plating for the impression of a structure into the surface portion of plastic-coated wooden or laminated boards. Each damaged spot is framed with a mask, etched and micro-metallised by micro-electroplating. In order to make it easier and less expensive to retouch or repair such plates, a galvanic solution is applied on the framed and etched damaged spots with less than 14 mm2 surface and an electrode tip is dipped therein to carry out a micro-electroplating. The etched damaged spot may be at first provided with a thin nickel layer by micro-electroplating and then with a copper layer which may then be structured by hand, if required, and coated with a cobalt hard layer. A microelectroplating device useful to carry out this process has a current rectifier with reversible poles, an electrode with a tip that can be dipped into the etchant or galvanic solution and a connector of opposite pole to be connected to the steel sheet.

Title: Method of mobile communication using orthogonal alert codes
Inventor: ESMAILZADEH RIAZ
IPC: H04W4/00
Filed: 1997-08-06
Abstract: In order to accomplish efficient communication of data between a base station and a plurality of mobile terminals, particular orthogonal codes are transmitted from the mobile stations to the base station as alert signals indicating the presence of data to be transmitted. The base station checks whether particular orthogonal codes are contained in the alert signals, and when the particular orthogonal codes are detected in the alert signals, information representing the detected orthogonal codes and the schedules for transmitting the data from the mobile terminals to the base station are transmitted from the base station to the mobile terminals as an alert response to the alert signals. When the information representing the orthogonal codes used for the alert signals are contained in the alert response transmitted from the base station to the mobile terminals, the data waiting to be transmitted is transmitted from the mobile terminals to the base station according the data transmission schedules in the alert response.

IPC: G06F12/08
Filed: 1996-06-04
Abstract: A disk drive (106) in a computer system is equipped with a power storage unit (118) that supplies power to the drive controller (110) when there is a system power interruption, such as a power down or failure.  Once the controller is notified that the system power has been interrupted, it will immediately initiate a seek to a reserved location in the disk drive and store the contents of the cache memory (112) there. After power has been restored to the system, the controller can load the contents of the reserved cylinders back to the cache memory and complete the pending write opeations by writing all of the data items in the cache to their final locations in the drive. Only one write operation is necessary, and this requires much less power than completing a plurality of pending write operations for the items in the cache to scattered locations in the drive.

Title: Electromagnetic anti-shoplifting system
Inventor: FELDBERG SIMON
IPC: G08B13/24
Filed: 1998-05-19
Abstract: The present invention provides an antitheft system to detect the presence of an object which has a label affixed thereto when said object passes through a surveillance zone comprising an oscillatory electromagnetic interrogation field having three separate and distinct vector components produced by driving the transmitting coils located in housing on either side of said surveillance zone with an alternating power source repetitively in and out of phase with respect to one another so as to form magnetic lines of flux having one vector component in the out-of-phase mode. The signals generated by the label are received by coils in said housing and are processed by electronic circuitry adapted to distinguish said label signals from spurious signals with a high degree of accuracy. The label can be deactivated so as to pass through the surveillance zone without triggering a system response.

Title: Apparatus and method for providing a beacon signal in a wireless communication system
Inventor: KAMIN RALPH A JR
IPC: H01Q3/40
Filed: 1997-07-01
Abstract: A beacon signal (313) is provided in a wireless communication system using a  hybrid matrix (303) and an inverse hybrid matrix (306). Using an unused port  of the hybrid matrix (303), the beacon signal (313) is combined with traffic  signals (316) intended for users of the wireless communication system. The hybrid matrix (303) transforms beacon signal (313) and the traffic signals (316) into output signals that each contain a portion of the beacon signal (313) and the traffic signals (316). The outputs from the hybrid matrix (303 ) are amplified by amplifiers (315). The outputs from the amplifiers (315) are  then inverse transformed by an inverse hybrid matrix (306). The inverse transform matrix (306) recombines the portions of the beacon signal (313) an d the traffic signals (316) originally input to the hybrid matrix (303), and t he resulting signals are transmitted using sector antennas (320) and a beacon antenna (323).

Title: Apparatus for helically assembling at least two filaments
Inventor: BRAZEAU MICHEL
IPC: D07B7/06
Filed: 1998-04-17
Abstract: An apparatus for helically assembling filaments on an advancing core or about a common axis comprises a supply spool assembly mounted for rotation about an axis and having filaments wound thereon, and a flyer mounted for rotation about the same axis so that rotational movement thereof encompasses the supply spool assembly. The filaments are directly guided from the supply spool assembly onto the flyer to minimize the backtwist effect. The filaments are wound together as they pass through a closing die. A capstan is provided downstream of the closing die to impart an advancing speed to the filaments. A control system allows for the control of the number of revolutions of the flyer per unit length of filaments advancing through the closing die to obtain a constant helical pitch. The tension in the filaments is controlled by hysteresis brakes acting on the supply spool assembly. The control system is operational to adjust the torque exerted by the brakes as filaments are unwound from the supply spool assembly.
