Patent CA-2250723-A1 (CA)
Title: Multiple epitope fusion protein
Inventor: CHIEN DAVID YING
IPC: C12P21/04
Filed: 1997-05-23
Abstract: Multiple copy epitope immunoassays are produced by: (1) identifying nucleotide sequences that encode a plurality of different epitopes; (2) placing the nucleotide sequences into an expression cassette wherein at least two copies of a sequence coding for the same epitope, preferably from different strains of a pathogen, are placed in the cassette; (3) transforming a suitable host with the cassette in order to express the sequences encoding the epitopes; (4) purifying the expressed epitopes; and (5) coating the epitopes on a surface of a substrate. The purified epitopes are encompassed by the general structural formula (A)x-(B)y-(C)z which represents a linear amino acid sequence, B is an amino acid sequence of an epitope or cluster of epitopes and each B contains at least five and not more than 1,000 amino acids, y is an integer of 2 or more, A and C are each independently an amino acid sequence of an epitope or cluster of epitopes not adjacent to B in nature and x and z are each independently an integer of 0 or more wherein at least one of x and z is 1 or more. The epitopes of the invention are more soluble than and are therefore more easily purified than conventional epitopes. Further, the presence of repeating epitope sequences (repeating at least B in the same linear amino acid sequence from different strains of a pathogen) increases the sensitivity and specificity of the assay. Repeated epitope sequences in a single linear antigen also decreases masking problems and makes it possible to include a greater number of epitopes on a unit area of substrate thereby improving sensitivity in the detection of antibodies.

Patent CA-2267873-A1 (CA)
Inventor: GRAHAM PAUL W L
IPC: G01B11/06
Filed: 1999-03-31
Abstract: Apparatus far measuring glass layer thickness in the sidewall of a glass container in which a container is placed in a bath of oil having an index of refraction matching that of the container outer sidewall surface. The body of the container is engaged within the bath to permit rotation while restraining lateral motion as the finish of the container is rotated. Light energy is directed through the bath and tangentially through the sidewall of the container so as to establish a pattern of light energy as a function of sidewall layer thickness, and layer thickness is determined as a function of such light pattern. As applied specifically to measuring thickness of the casing glass layer in a cased glass container in accordance with the preferred method of the invention, such casing glass thickness is determined as a function of the pattern in the light energy that emerges from the oil bath.

Title: Vehicle headlamp having a light shield
Inventor: FRAIZER ROBERT L
IPC: F21V11/16
Filed: 1999-04-06
Abstract: A vehicle headlamp having a light shield that does not outgas under normal lamp operation is disclosed. The vehicle headlamp uses a light shield with an interior surface with a rough, black ceramic coating. The ceramic surface absorbs almost all the visible light shone on it.

Abstract: L'invention concerne un procédé amélioré permettant d'effectuer la synthèse de l'urée à partir de l'ammoniaque et du dioxyde de carbone, en utilisant un condenseur placé verticalement ou horizontalement, afin d'éviter la corrosion des zones dans lesquelles la plaque tubulaire du condenseur se rattache aux tuyaux de refroidissement et où il y a contact avec un condensat. Spécifiquement, l'invention concerne un procédé qui consiste à séparer l'ammoniaque et le dioxyde de carbone que la réaction n'a pas altérés, sous forme de mélange gazeux combinant les deux, en travaillant à partir d'une solution de synthèse de l'urée sous une pression pratiquement égale à celle de la synthèse de l'urée, puis en mettant le mélange gazeux au contact d'un absorbant dans un condenseur, via un tuyau de synthèse de l'urée, de manière à préparer l'urée. Dans l'opération, les zones où la plaque tubulaire du condenseur se rattache aux tuyaux de refroidissement et où il y a contact avec le condensat sont recouvertes d'ammoniaque ou d'un liquide riche en ammoniaque, ce qui permet de protéger lesdites zones contre la corrosion.

Title: Article carrier for a vehicle
Inventor: DE SILVA AMESH
IPC: B60R9/045
Filed: 1999-04-20
Abstract: The present invention relates to an article carrier assembly for installation on a generally upwardly facing surface of a motor vehicle. The assembly comprises first and second elongated side rails each having locking member engaging portions.  Preferably, the locking member engaging portions are spaced apart apertures, although the present invention is not intended to be limited in such a manner. The side rails mount on the generally upwardly facing surface of the motor vehicle in spaced apart, generally parallel relation. An adjustable cross rail assembly has an elongated cross rail for supporting articles of cargo, a fixed locking member fixedly mounted on one opposing end portion of the cross rail, and a selectively movable locking member movably mounted on the other opposing end portion of the cross rail. The movable locking member is selectively movable between a locked position and an unlocked position. The cross rail assembly mounts in an operative position with the cross rail extending transversely between the side rails, the fixed locking member engaging the engaging portion of the first side rail, and the movable locking member being moved to the locked position thereof and engaging the engaging portion of the second side rail. Together, the fixed and movable locking members cooperate with the locking member engaging portions to prevent longitudinal movement of the cross rail assembly with respect to the side rails. The cross rail assembly can be repositioned longitudinally with respect to the side rails from one side of the vehicle by manually affecting movement of the movable locking member to the unlocked position thereof so as to disengage it from the engaging portion of the second side rail, then moving the cross rail assembly so as to disengage the fixed locking member from the engaging portion of the first side rail, then moving the cross rail assembly longitudinally with respect to the cross rail, and thereafter re-engaging the fixed locking member with the engaging portion of the first side rail and manually affecting movement of the movable locking member into the locked position thereof into engagement with the engaging portion of the second side rail.

Title: Dynamic address assignment for wireless devices accessing packet-based wired networks
Inventor: LA PORTA THOMAS F
IPC: H04L29/12
Filed: 1999-10-27
Abstract: The number of packet routing addresses utilized within a wired subnet offering wireless services via subnet base stations is reduced by assigning a packet routing address to a wireless device accessing a wired subnet upon power up of the wireless device. A Dynamic Host Configuration Protocol (DHCP) server is utilized to assign the packet routing addresses, and supplies addresses either directly or indirectly via a node acting as a DHCP relay for a DHCP server. If the assigned packet routing address is a care-of address for a foreign domain, the address is released upon wireless device power down or upon handoff of the wireless device to a new domain. If the assigned packet routing address is an address for the wireless device within a home domain, the address is released upon wireless device power down.
