Patent CA-2056185-A1 (CA)
Title: Multistage amplifier
Inventor: SHIGA NOBUO
IPC: H01P3/08
Filed: 1991-11-26
Abstract: A multistage amplifier for amplifying an input signal so as to output an amplified signal. The multistage amplifier is comprised of a plurality of transistors that are monolithically formed around a central VIA hole.  Predetermined electrodes of the respective transistors are electrically connected to each other in the area immediately surrounding the central VIA hole and are connected to the VIA hole itself.  This allows for a reduction of the number of VIA holes used over conventional methods.  The distance between the central VIA hole and the predetermined electrodes of each of the transistors is minimal, as is the wiring pattern of each of the electrodes.  No scattering is caused by the characteristics of the transistors, as they are monolithically formed in the same manufacturing process.

Title: Distributed switching in bidirectional multiplex section-switched ring transmission systems
Inventor: MARRA WILLIAM C
IPC: H04Q11/04
Filed: 1993-04-22
Abstract: Long delays in bidirectional multiplex section-switched self-healing ring transmission systems are avoided by eliminating looping of communications signals when restoring them in response to a failure in the ring and by distributing switching of paths to be protected to ring nodes other than those immediately adjacent the failure. This is realized by provisioning each node in the bidirectional multiplex section-switched ring transmission system with a map of its traffic pattern (all active tributaries) and the relative position of each ring node in the ringtransmission system, and allowing the ring node, if it has communications traffic affected by the failure, to bridge and switch to and from the protection path.

Title: Load sharing method and apparatus for controlling a main gas parameter compressor station with multiple dynamic compressors
Inventor: STAROSELSKY NAUM DR
IPC: F04D27/00
Filed: 1993-06-22
Abstract: Abstract of the Disclosure A method and apparatus for maintaining a main process gas parameter such as suction pressure discharge pressure, discharge flow, etc. of a compressor station with multiple dynamic compressors, which enables a station controller controlling the main process gas parameter to increase or decrease the total station performance to restore the main process gas parameter to a required level, first by simultaneous change of performances of all individual compressors, for example, by decreasing their speeds, and then after operating points of all machines reach their respective surge control lines, by simultaneous opening of individual antisurge valves.  In the proposed load-sharing scheme, one compressor is automatically selected as a leading machine.  For parallel operation, the compressor which is selected as the leader is the one having the largest distance to its surge control line.  For series operation, the leader has the lowest criterion "R" value representing both the distance to its surge control line and the equivalent mass flow rate through the compressor.  The leader is followed by the rest of the compressors, which equalize their distances to the respective surge control lines or criterions "R" with respect to that of the leader.
