Patent CA-2508497-A1 (CA)
Title: Wheel attachment system
Inventor: MARTINEZ AUGUSTO H
IPC: B60B23/00
Filed: 2005-05-27
Abstract: A vehicle wheel attachment system for facilitating mechanical coupling of a vehicle wheel to a vehicle includes a hub assembly having a piston which exerts force against a compression fitting. The hub assembly is passed through a wheel and attached to a rotor. In one embodiment, the hub assembly is mechanically torqued to clamp the wheel between the hub assembly and the rotor. Pressure in the system is maintained by a spring biasing means, and in particular, a spring cone washer. After removal of the torquing fixture, pressure in the system is maintained by use of a spring cone washer that acts against a compression plate held in place by a split ring assembly. In alternative embodiments, the wheel and hub mandrel shapes can be modified in order to correspond to one another, and thus assist in locking the wheel to the hub. As a result, a rapid, non-hydraulic method for attaching a vehicle wheel to a vehicle hub assembly is provided.

Title: Methods for the treatment and prevention of diseases of biological conduits
Inventor: ROMANO CHARLES P
IPC: A61F2/958
Filed: 2004-02-20
Abstract: Methods are described for dilating biological conduits by removing elastin and remodeling collagens in the wall of the conduit. Methods include the use of agents that increase the release of endogenous elastase and collagenase in the wall of the conduit, either by cells that are normally present in the wall of the conduit or by inflammatory cells that are attracted to the conduit, thereby providing additional conduit dilation. Methods also include the use of agents that increase conduit wall permeability and expose elastin and collagen fibers. Methods also include removing components of the extracellular matrix of arteries and veins leading to an inhibition of intimal hyperplasia in the wall of the vessels by decreasing biomechanical stimuli directed toward the cells in the wall of the vessel. Methods further include the use of agent that degrade microfibers, in addition to elastin, in order to decrease the resynthesis of elastin. Methods also include the use of agent that stabilize the diameter of aneurysmal arteries by blocking cell surface receptors in the wall of the aneurysmal artery that are important in the recruitment of inflammatory cells.

Title: Cpu-controlled, rearming, high voltage output circuit for electronic animal trap
Inventor: ANDERSON DAVID L
IPC: A01M23/38
Filed: 2003-11-12
Abstract: An electronic animal trap with a CPU-controlled, rearming, high voltage output circuit for trapping and exterminating pests. The high-voltage out put circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a period of time constituting a killing cycle when a known impedance is sensed across the plates. If, upon conclusion of the killing cycle, the impedance remains across the plates, the circuit activates a visual indicator to alert a user that the trap contains a dead mouse. However, if the impedance increases to that of an open circuit, likely meaning the animal has escaped, the circuit automatically rearms itself and no visual indicator is initiated.

Title: Multi-layer forming fabrics with packing yarns
Inventor: MARTIN CHAD AARON
IPC: D21F1/00
Filed: 2004-04-30
Abstract: A papermaker's fabric, usable in the forming section of a paper machine, having a top layer and a bottom layer of cross-machine direction (CD) wefts.  The top (forming) layer and bottom (wear side) layer are woven together to form a multi-layer fabric. CD packing yarns are inserted between adjacent wear side weft yarns.

Abstract: The invention relates to a process for producing a cast metal strip using a two-roll casting device. This device comprises two casting rolls and two side plates, which together form a melt space and a casting gap, with metal melt being fed into the melt space and in the melt space forming a melt bath with a bath surface which is open at the top, and a cast metal strip being delivered from the melt space through the casting gap. A delimited surface region (30) for the collection of particles which are foreign to the melt is formed on the bath surface under the action of at least one gas jet (20, 20a, 20b). To substantially avoid the introduction of particles which are foreign to the melt into the surface or the region close to the surface of the cast strip, it is proposed that the at least one gas jet (20, 20a, 20b) be directed on to the bath surface with the gas jet axis (21) at a distance from the contact line (10, 11) between the bath surface (8) and the casting roll (1, 2).

Title: Method for the production of fusion proteins in transgenic mammal milk
Inventor: COX GEOFFREY F
IPC: C12Q/
Filed: 2004-09-03
Abstract: Desirable fusion proteins can be produced in and purified from the milk of transgenic animals. The peptides are made as fusion proteins with a suitable fusion partner such as human alpha-fetoprotein. The fusion partner protein acts to promote and increase the half-life of the overall molecule as well as having therapeutic effects on its own. The fusion protein is typically produced through the use of transgenic animals and can be purified away from the now the milk or other bodily fluid of such an animal by an affinity purification method. A particular advantage of producing peptides via this route, in addition to the obvious advantages of high yield and biocompatibility, is that specific post-translational modifications, such as carboxy terminal amidation, can be performed in the mammary gland.  Biologically active polypeptides comprising a therapeutically active polypeptide fused to human alpha-fetoprotein fragment or a variant thereof, methods for the preparation thereof, nucleotide sequences encoding such fusion polypeptides, expression cassettes comprising such nucleotide sequences, self-replicating plasmids containing such expression cassettes, and pharmaceutical compositions containing said fusion polypeptides.

Title: Method and apparatus for desynchronization of neural brain activity
Inventor: TASS PETER
IPC: A61N1/08
Filed: 2004-10-20
Abstract: The invention relates to a device for desynchronising neuronal, morbidly synchronous cerebral activity. According to the invention, the activity in at least two sub-sections of a cerebral area or at least two functionally allied cerebral areas is stimulated with the aid of at least two electrodes, which surprisingly causes a desyncronisation in the affected neurone population of an afflicted person, thus suppressing the symptoms. The stimulation feedback signal, i.e. the measured, time-delayed and processed neuronal activity is used as the individual stimulus. The invention thus permits a self-regulating demand control of the amplitude of the stimulation signal, whereby the intensity of the stimulation pulses are automatically minimised after successful desynchronisation. To operate successfully, the device requires neither complex calibration nor regulation of the stimulation parameters, the latter however can be advantageously adapted and optimised by the additional controller. Said device comprises at least two stimulating electrodes (2) and at least one sensor (3), which are controlled by a controller in such a way that they cause localised desynchronisation.
