Title: Inserting tubular members in wells
Inventor: MILBERGER LIONEL JOHN
IPC: E21B33/038
Filed: 1991-08-28
Abstract: A running tool 27 allows an upper tubular member 19 to be inserted into a lower tubular member 11 in a well without damage to sealing surfaces 23. The upper tubular member 19 has a first side and a sealing section 23 on a second side. A running tool 27 with a tubular sidewall locates on the upper tubular member. Seals 31 on the running tool 27 engage the first side opposite the sealing section. These seals 31 isolate a pressure area 29 on the opposite side from the sealing section. While running into the well, hydrostatic pressure communicates with the sealing section. A pressure differential between the isolated area 29 and the sealing section results in a radial force. The radial force deflects the sealing section radially. This allows the members to be inserted into each other with the sealing section spaced from the sealing surface of the lower tubular member. Once in place, moving the running tool 27 upward equalizes the pressure across the sealing section. The sealing section 23 springs into engagement with the sealing surface 15 of the lower tubular member 11. <IMAGE>

Title: Extended home system identification for cellular radiotelephone systems
Inventor: GERSZBERG IRWIN
IPC: H04W8/18
Filed: 1992-06-09
Abstract: Transitions of a mobile radiotelephone (159) between operating on A band service and B band service are controlled to enable the mobile radiotelephone to utilize the bands of a single service provider (132, 152) over a wide area of cellular service areas (101, 150) in which service is provided on either A or B bands by that single service provider. Each mobile radiotelephone served by a single service provider has an extended home system identification entered into its number assignment module (NAM). When the mobile radiotelephone is operating in a roam mode it scans both the A and B bands searching for the extended home system identification. If the system is successful in locking onto one of the extended home system identification channels, the mobile radiotelephone uses that setup channel to establish and receive calls from its original service provider within the present service area. If the lockup can not be made, the mobile radiotelephone uses the system I.D. and the A or B band as normally set in the NAM. <IMAGE>

Patent GB-2299240-A (GB)
Title: Digital communications system
Inventor: MAUGER ROY HAROLD
IPC: H04L49/111
Filed: 1995-03-24
Abstract: In an ATM network a flexible AAL1 processor is connected to a similar AAL1 processor by a virtual circuit. This virtual circuit has nx64kb/s capacity wherein each 64kb/s channel or a Px64kb/s subset of the capacity can be used for a separate call. The virtual circuit behaves similarly to trunk groups within present day digital networks and it is therefore termed a Virtual Trunk Group. Many Virtual Trunk Groups can be connected between the same two endpoints and contained within a virtual path thus forming a Virtual Route. The network is provided with a mechanism which allows the nx64kb/s capacity to be changed by a managed process which ensures that established calls are not affected by the change of capacity. This change of capacity is performed in such a way that the clock systems of the two AAL1 processors are able to behave in the normal manner for synchronised or plesiochronous switching networks without incurring additional frame slips in the AAL1 data stream. Frame slips due to the behaviour of the clock systems are still processed in the normal manner.
