Patent CA-2019458-C (CA)
Title: Rigid or flexible coupling for pipes
Inventor: HENRICKSON THOMAS R
IPC: F16L17/04
Filed: 1990-06-20
Granted: 1999-06-15
Abstract: A coupling for either rigidly or flexibly connecting the adjacent end of a pair of aligned pipes, is formed of a circular casing made of a pair of aligned, semi-circular segments which surround a resilient pipe gasket.  The opposite ends of the segments have radially outwardly extending lugs which form pairs of overlapping fastening lugs.  The lugs of at least one pair each have transversely aligned bolt holes and opposed sockets that are generally concentric with the bolt holes and open towards each other. A bolt extending through the sockets and bolt holes fasten the lugs together and cause the segments to clamp radially inwardly towards the pipes for coupling the pipes together with some permissible flexibility of relative movement.  A plug having opposits and portions and a central bolt hole is removably fitted within the opposed lug sockets, with the bolt extending through its central bolt hole.  The plug end portions are offset from each other in an axial direction, relative to the axis of the coupling, so that tightening a nut on the bolt wedges the overlapped pair of lugs apart in an axial direction for causing the segments to clamp axially and radially against the pipes and rigidly hold them against relative  movement.

Title: Switch and its protocol for making dynamic connections
Inventor: BROWN PAUL J
IPC: H04L12/56
Filed: 1990-08-20
Granted: 1995-05-16
Abstract: A dynamic switch and its protocol for establishing dynamic connections in a link by the use of frames, each frame having an identification of the source of the frame, an identification of the destination of the frame for the requested  connection,  and  link  controls  to  maintain, initiate or terminate a connection between the source and the destination.   The frames are bounded by a start of frame delimiter and an end of frame delimiter which may also act as a connect link control and a disconnect link control, respectively, and the onnections are made through the dynamic  switch having dynamic-switch ports.  The state of a dynamic-switch port is changed dependent on its present state,  the dynamic connection requested, and the direction and type of frames passing through the dynamic-switch port.

Title: Automatic initialization of a distributed telecommunication system
Inventor: BALES BRUCE MERRILL
IPC: H04M3/42
Filed: 1992-10-22
Granted: 1997-03-25
Abstract: A communication switching system having a plurality of switching nodes in which each switching node upon initialization completely establishes its own internal configuration. This establishment of internal configuration includes the number and type of switching modules and within each switching module: type of module control processor, type of internal switching network, printed board carriers, type and number of auxiliary circuits, and type and number of link interfaces. Each unit of a switching module reports relevant information to the module control processor; and in turn, the module control processor reports its own information and the information of the other units to a node processor (the main processor within a switching node). Further, each switching node and interfaces of the switching node automatically identifies the other switching nodes connected by communication links and switching paths to those switching nodes. Each interface upon being initialized automatically performs low level initialization operations over the connected link with the far end interface. The interfaces then report the completion of the initialization operations to the connected switching nodes. Upon receiving thesereports, each switching node becomes aware of the existence of the links to other switching nodes. Each switching node then exchanges node numbers with the far end switching node connected via interfaces and communication links to establishthe hierarchy of switching nodes in the switching system.
