Title: Method for monitoring and controlling traffic in real time in an atm switching node
Inventor: RYOO IN-TAE
IPC: H04L47/20
Filed: 1999-05-18
Abstract: A method for monitoring and controlling traffic in real time at an asynchronous transfer mode (ATM) switching node, comprising the steps of retrieving the virtual path identifier (VPI)/virtual channel identifier (VCI) field and cell loss priority (CLP) field from the header of a received ATM cell to determine the validity of the cell by checking the effective value of the header for VPI/VCI field, comparing cell monitoring counter value (Cm) with cell control counter value (Cc) to detect violation of traffic parameter when the cell is determined to be valid, determining whether the present user's connection violates the negotiated parameter by means of traffic control data (Active_Idle) and CLP when the cell violates the traffic parameter, holding, tagging and discarding the cell according as the cell violates the negotiated parameter, transferring the result of controlling the valid cell to the physical layer to process the cell, and reporting the cell monitoring counter value to a control panel of upper hierarchy to reset the cell counter control value based on the cell monitoring counter value.

Inventor: BOLLA JEAN-MICHEL
IPC: C12P21/08
Filed: 1998-03-25
Abstract: The invention relates to a porin gene from Campylobacter jejuni ¢SEQ ID NO:3!. The gene has been designated porA and is 1275 bp in length and expresses a protein of 45.6 kDa having a pI of 4.44 ¢SEQ ID NO:2!. The sequencing and cloning of the gene makes possible various medical and industrial uses. For examples, knowledge of the DNA code makes it possible to design DNA probes for identification of the gene in samples for testing. A positive result indicates the presence of the gene in the sample and is a strong indicator of the presence of C. jejuni. Such probes can also be used to isolate the corresponding cDNA, that may then be amplified by polymerase chain reaction. The development of DNA probes based on a known sequence is a known procedure that is familiar to persons skilled in the art and it will be possible for such persons to develop suitable probes without undue experimentation. Normally, such probes would consist of at least 15 consecutive nucleotides from the cDNA sequence.

Title: Flow control valve assembly
Inventor: TURNER ROBERT
IPC: G05D9/04
Filed: 2000-05-26
Abstract: A fluid flow control valve (10) has a piston (43) in a first chamber (45), urged by a spring (46) to close fluid passages (36) interconnecting the first chamber (45) to a second chamber (51). A fluid level sensor (20) in a container (100) allows fluid to be bled from a downstream side of the first chamber (45), via a bleed passage (45), to enable the piston (43) to move to open the fluid passages (36). When the fluid sensor (20) detects that the fluid level (101 ) in the container (100) has reached a preset level, the fluid level sensor (20) shuts off flow through the bleed passage (45) and the equalization of the fluid pressure on both sides of the piston (43) in the first chamber (45) enables the spring (46) to move the piston (43) to close the fluid passages (36), shutting off fluid flow through the valve (40).
