Title: Molecular genetic construction of vaccine strains of pasteurellaceae
Inventor: TATUM FRED M
IPC: C07K14/285
Filed: 1997-05-07
Abstract: Tools for genetically engineering Pasteurellaceae are provided. Replication-conditional plasmids which are useful for the Pasteurellaceae have been isolated and characterized. The plasmids can be utilized for delivery of DNA segments into the Pasteurellaceae in situations where control of extrachromosomal replication desired, such as in achieving allelic exchange or site-directed mutagenesis. A restriction endonuclease, HsoI, was isolated from a bovine lung isolate of Haemophilus somnus. The enzyme was found to be a true isoschizomer of HinPI, a commercially available enzyme originally isolated from Haemophilus influenzae Pl. Commercially available HhaI methyl transferase was found to protect against cleavage by both enzymes.  Methylation of foreign plasmid DNA was found to enhance transformation of Haemophilus somnus in excess of four orders of magnitude.

Title: Communication system architecture, apparatus and management and signalling method therein
Inventor: PROZENIUK PERRY L
IPC: H04L12/70
Filed: 1999-10-18
Abstract: Constrained operation performance of exchanges (50) and switches (16, 216) of wireline communication systems (10) is mitigated and single entry point management of the system maintained through the provision of a distributed multi-service hub (MSH) sub-net (350) architecture in which individual MSHs (302-308) have hidden point codes (1001-1003). A signalling server (352) is able to translate an address of the MSH sub-net into a point code associated with an MSH entry point into the MSH sub- net, while dialled digit information pertaining to a service or party identifies a related MSH exit point from the MSH sub-net (350). A path can therefore be established, with the signalling server (352) further required to ensure that the hidden point code associated with the MSH exit point is translated back to the address of the MSH sub-net in onward routing of signalling messages to the dialled service or party. An intermediate element manager EM2 (312) isolates a management server OSS (54) from element managers (314-322) associated with the control of individual MSHs (302-310), with the intermediate EM2 (312) therefore providing a single address point to the OSS (54) while itself appearing as an OSS to the element managers (314-322) of individual MSHs (302-310). Signalling and management functions can therefore be consolidated at the intermediate EM2 (312) to increase efficiency and reduce overhead.

In addition, an attachment mechanism (77, 78) holds the base platform (26) on the box spring (24).
Patent CA-2288345-A1 (CA)
Inventor: JARVIS PETER KAREL
IPC: H04Q3/00
Filed: 1999-11-02
Abstract: Stimulus signalling protocols and message protocols are methods for transferring information over a communications network. Stimulus signalling protocols (e.g.    P-Phone) are typically used for connecting simple terminals to a more powerful host whereas message protocols (e.g. H.323 standard) are typically used to connect between such hosts. Equipment has typically been developed and manufactured for use with either but not both systems and this has led to the need for protocol conversion devices which are complex and time consuming to develop and maintain. Voice data is sent via an H.323 channel over a data network and associated P-Phone signalling data is sent via a T.120 channel as part of the H.323 call. This enables stimulus signalling protocol equipment (e.g. business telephony handsets) to be used in message protocol systems without the need for protocol conversion.

Patent CA-2297188-A1 (CA)
Inventor: CHILDS KURT EDWARD
IPC: A01D61/04
Filed: 2000-01-26
Abstract: A combine chain and slat crop conveyor includes a plurality of feed drum chain guides. Each chain guide is a generally cylindrical ring which encircles and is attached to the conveyor feed drum and is shaped as a "W" in cross section. Each chain guide includes two outer flanges which extend away from the feed drum surface at an angle, e.g. in a range from 20 to 70 degrees from parallel with the drum surface. The angled outer flanges insure that, as a chain starts to wander out of its path, it will get tighter, which forces it back toward the center of the guide ring. Each guide ring also has an elevated center portion which directly contacts the chain rollers, thus providing a rolling surface for the chain rollers, which puts all relative rolling motion and metal to metal contact between chain roller and roller pin.
