Title: Valve that is normally closed in the free state
Inventor: WILLIAMS DAVID LLOYD
IPC: A61F9/007
Filed: 2007-09-26
Abstract: A valve system comprising a valve design in which the valve is normally closed is disclosed. The normally closed valve can comprise a circular valve seal face formed by the underside of a rim of an elastomeric valve boss and a circular valve seat, which is formed by the rim of a through-hole molded into, for example, a plastic cassette, such that the valve seal face, the valve seat, and the through hole are concentric. The valve boss can be a hollow "mushroom" shaped valve boss, or a conical-shaped valve boss. If no force is applied to the inside surface of the valve boss, no fluid can pass through the valve as the valve seal face rests against the valve seat as a result of the steady free-state load created by the stretch of the valve boss over the slightly longer through hole. When a force is applied to the inside surface of the valve boss, the valve seal face is displaced from the valve seat, allowing fluid between the valve seal face and valve seat and then to pass between the valve boss and the inside surface of the through hole.

Patent CA-2607047-A1 (CA)
Inventor: EHLERS MARK S
IPC: F01N3/023
Filed: 2007-10-16
Abstract: A diesel particulate filter of a motor vehicle is cleaned of ash, typically using equipment already available in a service shop. The method of the invention cleans ash particles from the diesel particulate filter by generating a pressure wave and transmitting the pressure wave into a housing containing the diesel particulate filter. The pressure wave dislodges ash particulates from the filter, which can then be removed from the filter using an ash collecting apparatus, such as a shop vacuum. The method also uses an inflatable bladder in the filter apparatus to close access between the housing and the engine or outside environment.

Title: Affinity markers for human serum albumin
Inventor: HANEL ARTHUR M
IPC: A61K47/48
Filed: 1998-11-06
Abstract: Methods and compositions are provided for identifying compounds having affinity or complementarity to a target molecule.  Compounds according to the invention may be described by the formula E-C a-R-C  b-A, wherein E is a therapeutic or diagnostic agent, R is a reactive group. C a and C b are connector groups between E and R and between R and A, respectively, and A is a group having an affinity for human serum albumin, wherein affinity group A comprises a sequence of amino acid residues -O1-O2-X1-X2-B in which the amino acid residues are independently selected from the group of all twenty naturally occurring amino acids. Compounds according to the invention may be used for labeling the target molecule, particularly where the target molecule is naturally found in a complex mixture, such as a physiological fluid, like blood. By affinity labelling in vivo, the lifetime of physiologically active entities can be greatly enhanced by becoming bound to long-lived blood components. The covalently bound entity may also serve as an antagonist or agonist of a particular binding protein or as an enzyme inhibitor.
Patent CA-2628244-A1 (CA)
Title: Gel formation of polyelectrolyte aqueous solutions by thermally induced changes in ionization state
Inventor: FILION DOMINIC
IPC: C08L5/08
Filed: 2006-11-06
Abstract: There is disclosed aqueous solutions of polyelectrolytes that can be neutralized by increasing temperature, under suitable polyelectrolyte charge state conditions, in order to obtain a homogeneous gel. This can be achieved by adding an appropriate weak electrolyte to the polyelectrolyte so that an increase of temperature will lead to a spatially homogeneous neutralization of the polyelectrolyte via proton transfer between the polyelectrolyte and the weak electrolyte. The ability of such a system to be thermally sensitive and to gel upon heating relies on the temperature dependence of the ionization equilibrium for the two components. This thermally induced neutralization reduces electrostatic repulsion between polyelectrolyte molecules allowing the manifestation of attractive polyelectrolyte-polyelectrolyte hydrophobic interactions and hydrogen bonding that result in gel formation. These new kinds of thermo sensitive gels can be used for biomedical applications.
