Patent GB-2120042-A (GB)
Title: Fault detection arrangements for digital telecommunications exchanges
Inventor: ADAMS RICHARD WALTER
IPC: H04M3/12
Filed: 1982-04-28
Abstract: In order to help resolve the faulty resources (DLT, Timeswitch TSP0, TSP1 etc,) in a complex multi-resource system such as a digital telecommunications exchange each resource is provided with a fault counter with an alarm threshold detector. The pattern of paths in a switch block when a speech fault occurs affects quite substantially the incrementing of the fault counts and thus which resource overflows its threshold. Since a fault continues to be reported until the faulty resource is put out of service, the length of time the path remains set up influences the fault count thresholds significantly. If the traffic patterns were completely random across all the switch block resources, and each path reported only one fault, then the simple approach of incrementing each associated resource count until one overflows would be successful on most occasions for single plane speech alarms. However, a fundamental problem in a real exchange environment is that there are paths which are virtually permanently set up carrying critical signalling information. In this case using the above method causes fault thresholds to be exceeded for those DLT's carrying semi-permanent paths although they may not be actually faulty but have been used on more paths which included faulty equipment than the actual faulty resources. To overcome this problem the fault count analysis software in the common control system CCS is adapted as follows: When a DLT count matures, all time switch counts are checked. The first time switch count to fall within a predetermined tolerance (+/-2) of the threshold of the DLT is reported as the faulty resource and put into the "out of service state". If the current servicability state of the other time switches is such that a loss of service situation is provoked, or there is no time switch with a fault count in the tolerance range then the DLT is reported faulty.

Title: Set-back tipping of neckties
Inventor: BENNISON MICHAEL NEWSTEAD
IPC: D05B73/12
Filed: 1982-08-27
Abstract: In the tipping of neckties, that is to say the provision of a lining to the basic or face fabric at one or both ends, it is highly desirable that the seam by which the lining is attached to the face fabric should be set back from the edge of the tie on the reverse side thereof with the desired neatness of the tie at the corners without the expenditure of considerable time and manual dexterity. The problem is mitigated by guiding the needle of a sewing machine to stitch the face and lining fabrics together along sets of first and second lines meeting at a corner and forming the face fabric into upwardly projecting pleats at the corner. Special means are provided to ensure that each pleat, which provides fulness in the face fabric, is not stitched down to the lining, and to avoid the stretching of the fabric while initially forming the pleats. <IMAGE>

Title: Seismic exploration
Inventor: ALAM MUHAMMED SHAFIQUL
IPC: G01V1/20
Filed: 1983-11-28
Abstract: Existing cables, analogue or digital, used in marine seismic surveys have only one hydrophone group at each offset. The data quality so recorded is not always useful. The quality may be improved with increased hydrophones per group but the improvement is limited because only a limited number of hydrophones can be used in a group. The present invention provides a seismic cable with more than one hydrophone group, eg. 1, 2 and 3, at each offset and the the maximum number of hydrophones in each group. It is so assembled that when used, all its groups are substantially at the same water depth and it is towed by a ship substantially as one compact body. The multiple traces of data so recorded at each offset from each shot are mixed before gathering by common depth point fashion for stacking. <IMAGE>
