Abstract: An isolated ferritin fusion protein is provided in which ferritin is fused with a protein or peptide capable of being fused to ferritin without interfering with the polymeric self-assembly of the resulting fusion protein, and the protein may be of the endocapsid form when fused at the C terminus or an exocapsid form when fused at the N terminus. These fusion proteins may self-assemble into a variety of useful higher polymeric forms, e.g., capsid or other polymeric aggregate, and they are advantageous in that they are useful in a variety of applications, including human and veterinary vaccines and therapeutics, blood substitutes, image contrast agents, metal chelating agents, gelling agents, protein purification platforms, and therapeutic receptor-binding proteins.

Abstract: A browser for viewing data representing text, pictures, sounds, virtual reality worlds, links, or other objects, and organized in a hierarchical structure is provided to display and interact with links to the data. A retrieved set of data is displayed in a lens, and subsequently retried sets of data th at are deeper in the hierarchical structure are displayed in further stacked lenses, creating a visual representation of the hierarchy. A label on each lens provides information on the data originally displayed in the lens. A user ma y choose to view the originally displayed contents of any lens on the screen. A user may also modify a personal hierarchical data structure comprising links to sets of data in the first hierarchical structure. In doing so, a user creates an entirely new hierarchical structure that customizes the organization of data according to personal preferences and takes advantage of natural association to reduce the number of perceived levels in the new hierarchical data structure.
Patent CA-2492606-C (CA)
Inventor: LACHAMBRE DAN
IPC: B09C1/10
Filed: 2004-12-09
Granted: 2009-05-05
Abstract: A method of remediation of contaminants is described, which uses naturally occurring organisms. A first step involves determining that a substrate containing naturally occurring organisms is contaminated. A second step involves applying an aqueous solvent solution to the substrate. The solvent solution must have known properties of disrupting the substrate and contaminant interface. The solvent solution is applied in concentrations within a range of approximately 3% to 7%, so as to render the contaminants more accessible to naturally occurring organisms in the substrate, without killing the naturally occurring organisms. A third step involves monitoring the activities of the naturally occurring organisms and applying further applications of the solvent solution at intervals, as required, until the contaminants in the substrate are reduced to acceptable levels.

Abstract: A bearing includes an inner race having a rotational axis and an outer race sharing the rotational axis of the inner race. Rolling bearing members are constrained between the inner race and the outer race. A retention lip is provided which is adapted to maintain a peripheral opening of a constant gauge distance between and prevent relative axial movement of the inner race and the outer race. The gauge distance of the peripheral opening is adapted to allow free passage of the rolling bearing members, upon wear on the rolling bearing members reaches a predetermined level. The bearing provides a pass or fail indication, by falling apart when the rolling bearing members have exceeded the predetermined level of wear.

Title: Processes for transitioning between various polymerization catalysts
Inventor: BURDETT IAN D
IPC: C08F2/00
Filed: 2003-12-03
Granted: 2009-09-29
Abstract: The invention relates to processes for transitioning from a first polymerization reaction with a first catalyst system to a second polymerization reaction with a second catalyst system where the first and second catalyst systems are incompatible. The polymerization reaction is conducted in a polymerization zone of a gas phase fluidized bed reactor which contains a fluidized bed of polymer particles by an essentially continuous passage of monomer gases through the polymerization zone.

Title: Electrical connector and socket assemblies
Inventor: KENNEDY STEVEN CHARLES
IPC: H01R11/11
Filed: 2005-12-05
Granted: 2010-04-27
Abstract: An electrical connector assembly for a cable having a plurality of insulated conductors 20. The connector assembly comprises a body 70 having a respective recess for receiving a terminating pin 27' each of the conductors 20. A respective spigot 24' sealingly engages within each of the recesses and has a passage for receiving an associated one of the terminating pins27'. Furthermore a seal 23' is associated with each of the spigots 24' for sealing the spigot relative to the associated terminating pin 27'. The provision of a separate spigot 24' for each of the conductors and for sealing engagement within a respective recess in the body enables the spigots to be sealingly fitted to the conductors prior to each spigot being introduced into its recess and sealingly engaged therein. This provides improved insulation of the conductor and increased creepage distance between the mating electrical parts and the outer surface of the housing of the assembly. It also provides the additional advantage that the seal on the conductor tends to be smaller than in prior arrangements so that there is less thermal expansion of the seal when the parts get hot in a downhole environment.

Granted: 2010-09-07
Abstract: A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.

Title: Enhanced stability of proteins immobilized on nanoparticles
Inventor: DORDICK JONATHAN S
IPC: G01N33/53
Filed: 2005-09-07
Granted: 2012-05-08
Abstract: This invention is directed to the application of a previously unknown property of nanomaterials - its ability to enhance protein activity and stability at high temperatures, in organic solvents, and in polymer composites.  Nanomaterials such as single-walled carbon nanotubes (SWNTs) can significantly enhance enzyme function and stability in strongly denaturing environments.  Experimental results and theoretical analysis reveal that the enhancement in stability is a result of the curvature of these nanoscale materials, which suppresses unfavorable protein-protein interactions. The enhanced stability is also exploited in the preparation of highly stable and active nanocomposite films that resist nonspecific protein absorption, i.e., inhibit fouling of the films. The protein-nanoparticles conjugates represent a new generation of highly selective, active, and stable catalytic materials. Furthermore, the ability to enhance protein function by interfacing them with nanomaterials has a profound impact on applications ranging from biosensing, diagnostics, vaccines, drug delivery, and biochips, to novel hybrid materials that integrate biotic and abiotic components.
