Abstract: INTEGRATED DATA LINK CONTROLLER WITH SYNCHRONOUS LINK INTERFACE AND ASYNCHRONOUS HOST PROCESSOR INTERFACE            ABSTRACT OF THE DISCLOSURE      A single chip integrated data link control  (IDLC) device provides full duplex data throughput and versatile protocol  adaptation  between  variably  configured time channels on a high speed TDM digital link (e.g. T-1 or T-3 line) and a host data processing system. The device can handle multiple channels of voice and varied protocol data traffic, and thereby is suited for use in primary rate   ISDN   (Integrated   Services   Digital   Network) applications.   Synchronous   and   asynchronous   special purpose  logic  sections  in  the  device  respectively interface  with  the  network  and  a  bus  extending  to external processing systems.  Logic  in the  synchronous section   forms   plural-stage   receive and   transmit processing pipelines relative to the network interface. A "resource manager" element (RSM) and time swap (TS) RAM memory  operate  to  dynamically  vary  states  in  these pipelines in synchronism with channel time slots at the network  interface,  whereby  each  pipeline  operates  in multitasking mode to perform plural functions relative to each channel  during each  time  slot. The  device  also includes integrated memory queues in which communication data and channel status information are stacked relative to  the  device  interfaces.  Capacities  and  modes  of operation  of  these  queues  are  selected  to  minimize effects  on  chip  size,  throughput  and  cost,  while supporting   operations   in   the   synchronous   section pipelines  so  that  critical  time  dependencies  between consecutive pipeline stages,  and between the pipelines and external processors, are lessened.

Title: Call-load-control arrangement for an emergency-call-answering center
Inventor: VANACORE VINCENT DEAN
IPC: H04M3/51
Filed: 1991-10-18
Granted: 1995-12-05
Abstract: A call-load control arrangement for a first call-answering center, such as an E911 service PSAP, causes calls destined for the first center and not yet routed thereto to be rerouted by a central office from the central office directly to a second, alternate, call-answering center while the first center is in call overload. A function monitors current parameters of call-answering performance of the first center and periodically compares them against predetermined criteria of acceptable call-answering performance to determine whether call overload exists. In the E911 service PSAP, the function automatically closes and opens a switch to activate and deactivate the "night-service" or "trunk make-busy" link to cause the central office respectively to reroute calls away from, or to route calls to, the PSAP.

Title: Method of serging trouser-fly piece with slide fastener stringer attached thereto
Inventor: ISHIKAWA KIICHIRO
IPC: D05B37/04
Filed: 1992-08-31
Granted: 1995-10-31
Abstract: An improved method of serging a trouser-fly piece on a serging machine having a trimming cutter is disclosed wherein a continuous trouser-fly blank assembly is fed intermittently into a first feed path extending toward the movement of the trouser-fly piece being advanced by the serging unit. Then the continuous trouser-fly blank assembly is cut into a succession of elongate rectangular trouser-fly pieces each of which is subsequently advanced toward the serging unit along the first feed path. Thereafter, at least a corner of a leading end of the trouser-fly piece is trimmed by the trimming cutter and, substantially at the same time, one curved longitudinal edge of the trouser-fly piece including the trimmed corner is serged with a serge stitching. In this instance, the trouser-fly piece is caused to turn in one direction to move from the first feed path in a second feed path extending parallel to and aligned with the path of movement of the trouser-fly piece being advanced by the serging unit. With this rotational movement of the trouser-fly piece, the trimming cutter accurately traced a substantially arcuate trimming line passing across the corner. The serged trouser-fly piece is automatically discharged from the serging unit.
