Patent CA-2346569-A1 (CA)
Title: Cartridge product irradiator
Inventor: CHU RODERICK DIT HING
IPC: G21K5/10
Filed: 2001-05-07
Abstract: The present invention relates to a product irradiator having a cartridge loading system. The cartridge comprises a plurality of carriers or totes which are transported as a single mass into an irradiation chamber for radiation processing.  Products contained within the totes are irradiated while on the cartridge, but individual totes are transferred around the radioactive source by a tote transfer system. The cartridge product irradiator permits quick changes of cartridges thereby minimizing the time that the radioactive source is not in use, and also permits good radiation dose uniformity in products. The cartridge product irradiator is thus highly efficient and economical to use.

Title: Substantially non-toxic biologically active mucosal adjuvants in vertebrate subjects
Inventor: STAATS HERMAN F
IPC: A61K39/35
Filed: 1999-10-06
Abstract: A method of eliciting an immune response against an antigen in a vertebrate subject, the method comprising the steps of providing an antigen-adjuvant composition comprising the antigen and a substantially non-toxic adjuvant molecule having biological activity in mucosal tissues, and administering said antigen-adjuvant composition to the vertebrate subject in a manner such that initial contact occurs in mucosal tissue of the vertebrate subject, whereby an immune response is elicited. Cytokines are preferred adjuvants. Preferred cytokines are interleukin-1.alpha. (IL-1.alpha.) and interleukin-1.beta. (IL-1.beta.).
Patent CA-2348289-A1 (CA)
Inventor: HAHN NORBERT
IPC: B65G69/00
Filed: 1999-10-25
Abstract: A vehicle restraint for a truck loading dock includes an actuator that rides  up with a carriage (20) to sense that a truck's ICC bar is within a predetermined region before fully extending a restraining member (28) to engage the bar. The carriage and restraining member are raised and lowered b y a drive unit (42), such as a cable (60) extending from a winch. The winch ma y be attached directly to the carriage, or optionally remotely mounted to the dock. One end of the cable connects to a spring (64) that compensates for incidental vertical movement of the ICC bar caused by the truck being loaded  or unloaded. Large downward movement of the ICC bar is accommodated by a clutch (50) associated with the winch. For large upward movement, the winch automatically restarts to pull the carriage up to meet the new height of the  bar. An optional ICC bar deflector mounted at the base of the dock, along si de the carriage, wedges underneath an exceptionally low ICC bar as the truck backs into the dock. The deflector guides and lifts the low bar above the actuator to prevent premature and uncontrolled extension of the restraining member.

Patent CA-2351170-A1 (CA)
Inventor: HONG HYO JEONG
IPC: C07K16/46
Filed: 1999-11-17
Abstract: The present invention is directed to humanized antibodies that specifically bind the protein 4-1BB. The antibodies can be made by grafting of the complementarity determining regions (CDR's) of mouse monoclonal antibody to human 4-1BB to the remaining portions of a human antibody and by making further amino acid replacements. In addition, a pharmaceutical composition that includes the humanized antibody can be made and can be used to treat autoimmune diseases to suppress an immune response. The humanized antibody o f the invention has high affinity for human 4-1BB, and exhibits sequence similarity to human antibody. As a result, the pharmaceutical composition of  the present invention can be used to treat autoimmune disease and act as an immunosuppressant in humans without much side-effect.

Title: Bandwidth partitioning using emulated weighted fair queuing (ewfq)
Inventor: BARRACK CRAIG
IPC: H04L12/56
Filed: 2001-07-24
Abstract: A method of scheduling queue servicing in a data packet switching environment is provided. The method includes a sequence of cyclical steps. The output queues are scheduled for servicing on a least credit value basis.      An output queue is selected from a group of output queues associated with a communications port. The selected output port has at least one Payload Data Unit (PDU) pending transmission and a lowest credit value associated therewith. At least one PDU having a length is transmitted from the selected output queue and the credit value is incremented taking the length of the transmitted PDU into consideration. The transmission of PDUs is divided into transmission periods. Once per transmission period credit values associated with output queues holding PDUs pending transmission are decremented in accordance with transmission apportionments assigned for each output queue.      The method emulates weighted fair queue servicing with minimal computation enabling hardware implementation thereof.

Patent CA-2356435-A1 (CA)
Title: Moteur anti refoulement ii
Inventor: BEAUDOIN NORMAND
IPC: F02B75/00
Filed: 2001-07-31
Abstract: Lorsque l'on regarde les principaux types de moteurs commerciaux sur le marché, qu'ils soient à deux temps, à quatre temps ou encore de type rotatif, l'on constate que, et c'est là un lieu commun, ces moteurs sont très polluants. La raison principale de cet état de fait réside dans la difficulté de construire des filtres des gaz usés qui n'offriraient pas de restriction. Cette difficulté peut cependant être surmontée en produisant un moteur lui-même capable de supporter un haut niveau de restriction.  La présente solution technique présente donc plusieurs réalisations permetta nt au moteur d'accepter un haut taux de restriction et par conséquent une filtrati on plus dense. Ces diverses réalisations techniques établissent de façon nouvelle le parcours des gaz à travers le moteur. Dans la présente solution, ce n'est pa s d'abord l'alimentation en gaz neufs qui est visée, mais plutôt l'absorption des gaz usés, puis leur évacuation qui constituent le premier temps de ce moteur. En effet, les  gaz usés sont d'abord évacués vers l'extérieur, à travers deux étapes successives. En  effet les gaz sont évacués vers l'extérieur de façon pompée, et cette évacuation crée,  à son tour, un vide qui succionne de nouveaux gaz brûlés qui à leur tour aspirent finalement des gaz neufs. Ces techniques ont aussi l'avantage de produire de s moteurs deux temps mus seulement au gaz, et par conséquent plus propres et plus efficaces.

Title: Football passing game system
Inventor: ZUCCHI JEFFREY R
IPC: A63B63/00
Filed: 2002-04-29
Abstract: The present invention provides a football passing game system. A target with a number of target zone apertures of various sizes is mounted on a stand which holds the target a distance away from a player position. A game player attempts to pass a football through one of the defined target zone apertures.  At least one light sensor is mounted adjacent each of the target zones to detect the passage of a football through an aperture. An impact sensor is mounted to the target and detects if the football impacts the target instead of passing through a target zone aperture. When a signal is generated by a light sensor or the impact sensor, a controller mounted to the target detects the signal and calculates the corresponding change in the game status. The game status is displayed on an electronic display adjacent the target.
