IPC: C07K16/44
Filed: 1998-01-26
Abstract: The present invention relates to a method for in vitro creation of molecular libraries evolution of protein function. Particularly, it relates to variability and modification of protein function by shuffling polynucleotide sequence segments. A protein of desired characteristics can be obtained by incorporating variant peptide regions (variant motifs) into defined peptide regions (scaffold sequence). The variant motifs can be obtained from parent DNA which has been subjected to mutagenesis to create a plurality of differently mutated derivatives thereof or they can be obtained from in vivo sequences. These variant motifs can then be incorporated into a scaffold sequence and the resulting coded protein screened for desired characteristics. This method is ideally used for obtaining antibodies with desired characteristics by isolating individual CDR DNA sequences and incorporating them into a scaffold which may, for example, be from a totally different antibody.

Patent CA-2280207-A1 (CA)
Inventor: BAULCOMBE DAVID CHARLES
IPC: C12N15/84
Filed: 1998-02-12
Abstract: Disclosed are DNA constructs ("amplicons" TM) comprising a promoter operably linked to DNA which can be transcribed in a plant cell to an RNA transcript, which RNA transcript includes plant virus sequence (e.g. derived from potato virus X) which confers on the RNA transcript the ability to replicate in the cytoplasm of the plant cell. The constructs may lack portions of the viral genome not required for such replication (e.g. coat proteins) but preferably include targeting sequence which is capable of down-regulating (for instance gene silencing) expression of one or more target genes, which may be endogenous plant genes, transgenes, or pathogen genes. Also disclosed are corresponding vectors, host cells, plants (particularly having modified and/or silenced genes or being pathogen resistant) and plant products, plus also methods of producing and using these materials.
Patent CA-2281061-A1 (CA)
Inventor: LUKE ALVIN D
IPC: B62D33/04
Filed: 1999-08-24
Abstract: The invention is a pick-up truck bed cover for a fifth-wheel hitch. The cover is one-piece and is sized to fit over the front and side rails of the pick-up bed. The invented cover has a unitary top surface, which may be divided into several sections, or areas. One such area is a central recessed, but closed, channel extending forwardly from the back of the cover. This channel is for allowing the trailer hitch tongue to enter during coupling or uncoupling of the trailer. At the front end of the channel is a semi-circular or U-shaped area with an opening for receiving the trailer hitch tongue during towing use of the truck. The opening is located so that it is over the fifth-wheel connecting hitch installed in the bottom of the truck bed over the back axle. Preferably, the opening is covered by a tarp boot which is fastened around the outer edge of a raised flange that surrounds the opening. The tarp boot is constructed so that it extends from the raised flange up and around the goose neck of the trailer during towing use of the truck. When not towing, the tarp boot is folded down and fastened so that it keeps the weather out of the opening, and does not flap in the wind. The semi-circular or U-shaped area is partially surrounded by a central raised area that is lower than the side edges of the cover. This way, the cover, preferably made of plastic or fiberglass material, may be made in one, unitary piece.

Abstract: An in-situ well water system is described which removes arsenic from ground water contaminated by arsenic containing soils. A reactive, adsorptive barrier, consisting of iron containing material and filter media such as soils, sand and the like is described which surrounds the screened casing of the well. The system described can be constructed manually by relatively unskilled labour and most importantly does not produce a hazardous arsenic containing waste requiring disposal. The appropriate selection of materials, the physical dimensions, adjustment of the permeability through the use of dual media, reducing nature of the well water and the water head available determine the quantity and dimensions of the barrier.

Title: Pivot assembly for swiveling chair
Inventor: BELLEFLEUR PIERRE
IPC: A47C3/18
Filed: 1999-12-15
Abstract: The present invention relates to a pivot assembly for a swiveling chair. The pivot assembly includes an elongated rod received in a tubular element, the elongated rod being capable to pivot by the intermediary of bearing assemblies such as to allow the chair to swivel. Each bearing assembly includes two segments mechanically engaged with one another. Each bearing assembly is responsive to pressure tending to urge the segments toward one another such as to close itself on the elongated rod and thus reduce or eliminate any clearance that may develop between the elongated rod an the bearing assembly. This arrangement is useful because it eliminates or at least it reduces free play that may develop in the components of the pivot assembly over time.

Filed: 1999-06-10
Abstract: La présente invention concerne un système d'émission en anneau à multiplexage par répartition à longueur d'ondes (MRL), équipé de deux concentrateurs. Des groupes identiques de signaux optiques destinés à être émis sur l'anneau sont entrés dans les deux concentrateurs, mais l'un des concentrateurs comprend des commutateurs optiques destinés à faire passer sélectivement l'un des groupes de signaux optiques vers l'anneau MRL. En conséquence, si une faute se produit dans l'une des connexions concentrateur-réseau, ou si l'un des concentrateurs tombe en panne, les commutateurs couplent les signaux optiques du concentrateur en activité à l'anneau MRL. En outre, les signaux optiques émis par les noeuds couplés à l'anneau MRL sont sortis des deux concentrateurs, ce qui permet d'assurer la sortie et l'entrée de signaux dans l'anneau, même si l'un des concentrateurs tombe en panne.

Title: Information delivery in a multi-stream digital broadcasting system
Inventor: NORR WILLIAM M
IPC: G10L19/00
Filed: 2000-07-25
Abstract: Audio or other information is delivered to a user via a multi-stream digital broadcasting system in a partially-encrypted form. The information is encoded and separated into multiple bitstreams, at least a subset of which are left unencrypted. Both the encrypted and unencrypted bitstreams are received and stored by the user. A  user is able, for at least a limited period of time, to access the information at a first quality level, e.g., an FM-quality level for audio information, without having the corresponding decryption key, by utilizing only the unencrypted bitstreams. The user can then access an electronic-commerce web site to purchase the decryption key. The key may be downloaded from the site to an information processing device of the user, and may be utilized to decrypt the partially-encrypted format, such that the user is provided with access to the information at a second quality level higher than the first quality level, e.g., a CD-quality level for audio information. The multiple bitstreams may correspond, e.g., to subbands of at least first and second digital sidebands of a host carrier signal in an FM in-band on-channel (FM-IBOC) digital audio broadcasting system.
