Patent CA-2389213-A1 (CA)
Title: Production of catalyst layers on membranes for low-temperature fuel cells
Inventor: KUNDLER ISABEL
IPC: H01M8/1004
Filed: 2000-10-14
Abstract: The invention relates to a method for applying catalytically active material to a polymer membrane for low temperature fuel cells. According to the invention, a nonpolar solvent, a catalytically active material and a polymer solution are processed into a paste. This paste is then applied to the membrane in the form of a layer, especially by screen printing. The paste is then dried and pressed onto the membrane, heat being supplied. The use of nonpolar solvents prevents swellings from forming in the membrane. It is therefore possible to produce the desired product with only a few processing steps. Material losses are minimised by using the screen-printing technique.  The method is therefore economical and simple overall.

Title: Telescoping support device for fastener driving tool
Inventor: KOBETSKY ROBERT G
IPC: B25C7/00
Filed: 2002-07-09
Abstract: A support device for use within a fastener driving tool is fixedly attached to the tool s workpiece contact element so as to be movable therewith between extended and retracted positions. When the workpiece contact element, and the support device mounted thereon, are moved to the retracted position, a pocket or recessed portion of the support device will envelop a tip portion of a second uppermost fastener disposed within the tool magazine, while the first uppermost fastener is disposed within. the tool drive bore, such that the second uppermost fastener, as well as the remaining fasteners within the magazine, is properly supported and stabilized such that shock and vibrational forces, attendant the driving of the first uppermost fastener, are effectively prevented from being transmitted to the second uppermost and remaining fasteners. In addition, the pocket or recessed portion serves to partially close the magazine opening through which the fasteners are serially advanced such that the first uppermost fastener will be maintained coaxially aligned within the tool drive bore, and an upstream leading edge of the pocket or recessed portion also defines a shearing edge for properly shearing those portions of the collation strip which interconnect adjacent pairs of the fasteners within the collated strip of fasteners.

Title: Adjustable shock absorber
Inventor: SENDREA DARRYL
IPC: F16F9/32
Filed: 2002-08-19
Abstract: A shock absorber assembly includes a damping adjustment mechanism that can easily be incorporated into a twin cylinder design. The shock absorber includes an outer cylinder and an inner cylinder mounted within the outer cylinder. The inner cylinder is spaced apart from the outer cylinder to define a gap. A piston is mounted within a fluid filled chamber formed within the inner cylinder to dampen vibrations. Holes are drilled into the wall of the inner cylinder to provide fluid ports that can communicate with the gap to form a bi-directional fluid path as the piston moves back and forth within the chamber to dampen vibrations. To provide variable damping, the outer cylinder includes an eccentric inner diameter to outer diameter profile that allows damping adjustment between high and low damping forces. The damping force is adjusted by rotating the outer cylinder relative to the inner cylinder to vary the size of the gap with respect to the ports.

IPC: G01M13/00
Filed: 2001-05-16
Abstract: Method in monitoring the condition of machines, in which method measurements are performed on a number of machines or machine parts to obtain quantities descriptive of the condition of the machines. In the method, characteristics or symptoms related to the operation or condition of the machine are derived from the measured quantities, a characteristic vector describing the current operational state of the machine is generated from the characteristics, characteristic vector categories are formed from characteristic vectors describing the same operational state, and a database is created in which are stored characteristic vector categories describing different operational states of the machines. To analyze the operation of a machine, the characteristic vector is compared to the characteristic vector categories in the database and an alarm is activated if the characteristic vector being compared corresponds to a characteristic vector category describing a state of malfunction or if no characteristic vector category corresponding to the characteristic vector can be found in the database.
Patent CA-2411952-A1 (CA)
Inventor: SYKES CHRISTOPHER C
IPC: E04B2/74
Filed: 2002-11-15
Abstract: A partition structure comprising a rectangular peripheral frame has two spaced apart generally vertical members and two spaced apart generally horizontal members. The horizontal frame members are connected to the vertical frame members at the corners thereof. A substantially rigid panel section is connected to and confers rigidity to the frame. The panel may be compressed within inwardly facing channels of frame members.      Alternately portions of frame members may extend and be snugly fit into channel section edges of the panel, thereby eliminating the need for attachment means to secure the panel sections to the frame members. The provision of a partition structure having panels which provide rigidity to the frame structure, allows the use of a frame structure which is not particularly rigid itself.

Abstract: L'invention concerne des banques comprenant des molécules de liaison lesquelles sont adaptées à une expression dans un organisme d'expression, mais lesquelles sont également transférables dans un contexte humain sans subir de changement de conformation et/ou de développement. Dans ce cadre, l'invention concerne une méthode de production d'un anticorps monoclonal humain, ladite méthode consistant à produire une banque de molécules de liaison dont le domaine de liaison comprend essentiellement des fragments variables de chaînes lourdes humaines en un format fonctionnel, à sélectionner dans ladite banque au moins un fragment variable de chaîne lourde ayant une affinité de liaison voulue et à insérer un acide nucléique codant ledit fragment variable de chaîne lourde dans un acide nucléique codant la partie complémentaire d'au moins une chaîne lourde dudit anticorps monoclonal humain, à permettre l'expression de la chaîne lourde résultante et l'assemblage de ladite chaîne lourde avec une chaîne légère voulue, et à produire un anticorps monoclonal humain. La conformation dudit fragment variable de chaîne lourde est telle qu'il conserve son affinité de liaison qu'il se trouve dans un environnement de présentation de phage ou dans son environnement de chaîne lourde normal. L'invention concerne également une méthode de production d'une banque destinée à être utilisée dans ladite méthode, de même que des méthodes de conservation de fragments variables de chaînes lourdes dans ladite conformation. La présente invention permet la production de banques plus grandes que celles connues tout en permettant de réduire la perte de spécificités et d'affinités du fait de problèmes d'expression.

Title: Cathodic protection system utilizing a membrane
Inventor: RUSSELL GORDON I
IPC: C23F13/06
Filed: 2001-11-16
Abstract: A cathodic protection system for corrosion protection of metallic structures in contact with aqueous solutions such as salt water and calcium chloride brine. The system employs anode chambers containing hydroxide anolytes segregated from the electrolyte containing chloride by an ion-exchange membrane. The anode and the structures to be protected are coupled to voltage and current sources impressing current at the immersed surfaces of metallic structures to maintain these surfaces close to an equipotential and covered with a bound layer of polarized hydroxide. The preferred embodiment is used in connection with stainless steel holding tanks and associated equipment used to circulate calcium chloride brine to freeze whole muscle turkeys. When the brine and the anolyte contact the membrane, a bi-ionic potential forms across the membrane that drives the counter-directed transport of ions through the membrane, thereby preventing the anodic production of C12. Additionally, pH  control is employed and a controller is coupled to one or more of a series of reference electrodes used to monitor the potential differences between the electrodes and the metal surfaces to be cathodically protected. If the potential difference falls outside of a predetermined range, due to changing exposure conditions and/or operating parameters, the applied voltage is adjusted so that the current from the anode produces a polarized and alkaline protective film at the metallic surfaces of the holding tank and associated equipment so as to counteract and overcome the corrosive properties of the brine.
