Title: Method and apparatus for enhancing signalling reliability in a cellular mobile radio telephone system
Inventor: GHISLER WALTER
IPC: H04B7/26
Filed: 1991-08-06
Abstract: A method and apparatus for achieving reliable transmission of signalling messages in a cellular system in which the frequency plan, frequency/time slot allocation plan, code channel allocation plan, or dynamic/adaptive channel allocation rule of the system is violated by allowing adjacent base stations to reuse particular frequencies/time slots/channels for signalling a particular mobile station. In situations where signalling messages, such as handoff commands, which are communicated between a base station and a mobile station are not properly received by the mobile station, an alternate communications channel will be established to ensure the reception of these messages. The alternate channel is provided by repeating the message through a channel associated with a base station which has better radio characteristics. The channel selected for transmission of the message by the new base station will be on the same frequency/time slot/code as used by the established connection.

Title: Trouser-fly piece serging apparatus
Inventor: DUDEK CHET
IPC: D05B35/10
Filed: 1991-09-06
Abstract: A  trouser-fly piece serging apparatus includes a guide unit disposed upstream of a serging station and composed of a first elongate guide member extending at an angle relative to the path of movement of a trouser-fly piece being advanced by a serging unit, and a second elongate guide member extending parallel to the path of movement of the trouser-fly piece.  The trouser-fly piece is guided by the first guide member into the serging station so that a trimming cutter disposed immediately upstream of the serging unit assumes a position to conform to a curvature of the leading end of a substantially arcuate trimming line passing across a corner of the leading end of the trouser-fly piece.  Synchronous operation of the serging unit and the trimming cutter causes the trouser-fly piece to turn in one direction during which an arcuate corner which is trimmed by the trimming cutter and subsequently serged by the serging unit is automatically produced on the leading end of the trouser-fly piece.  Then, the trouser-fly piece is guided by the second guide member, and as the trouser-fly piece is further advanced, a curved longitudinal edge of the trouser-fly piece including the trimmed arcuate corner is completely serged with an overedge or serge stitching.

Filed: 1992-02-21
Abstract: In a communication apparatus in which a first level unit, a second level unit and a third level unit are hierarchically arranged and these units are connected to one another by multicore cables, one of the many cores of each multicore cable is used as monitoring core, and the first level unit sends out to each monitoring core a probe signal generated by sampling the digital signals supplied via the individual cores of the multicore cable and multiplexing them on a time-division basis.  The second level unit compares each of these probe signals and a string of signal samples supplied via the multicore cable corresponding to this probe signal, generates a faulty connection indicating signal in response to any discrepancy between them; generates, similarly to the first level unit, a probe signal for detecting any faulty connection between the second level and third level units; multiplexes these signals on a time-division basis; and inserts the multiplexed signal into the monitoring core to the third level unit.         The third level unit, on the basis of the probe signal for this signal supplied via the monitoring core, can display a faulty connection signal both for each multicore cable and for each individual core.
