Patent CA-2424437-A1 (CA)
Inventor: ROSS GUY
IPC: E01C3/06
Filed: 2003-04-04
Abstract: A method of forming a shielded asphalt surface on a prepared subgrade for a roadway, or the like, to prevent water infiltration, freeze-thaw cycles, and roots from damaging the surface. The method involves forming a recess along the outer edges of the subgrade;  depositing asphalt into the recess and compacting the deposited asphalt to form an edge portion at about the same height as the subgrade; depositing asphalt onto the subgrade to form the roadway surface and also onto the edge portion; compacting the deposited asphalt thereby integrating the asphalt that forms the roadway surface with the asphalt that forms the edge portion to provide a monolithic shielded asphalt surface.

Inventor: THIRUVALLUVAR CHELIYAN
IPC: A46B17/02
Filed: 2003-05-20
Abstract: Autobrush: A novel device made of plastic components to hold toothpaste, toothbrush and tongue cleaner together. Autobrush works as a holder at the same time it can deliver toothpaste right on top of the toothbrush Autobrush is a convenient device which makes brushing easy.      Autobrush can be fixed to the wall of the washroom. Autobrush has three major components. The body is one of the major components, which is a half ellipse container, having a hollow space at the center of the back from top to the bottom. The second major part of the autobrush is the lid, which is mounted to the top of the body. The last and the most important part of the autobrush is the pump. The pump is fixed at the bottom of the body to deliver the toothpaste right on top of the toothbrush. The toothbrushes and tongue-cleaners are inserted vertically through the lid in such a way that the top of the toothbrush containing the bristles rests on the bottom of the body and the butt is leading outside. The mouth of the toothpaste is screwed into the pump in a vertical upside down position inside the hollow part of the body. The pump has a specific location fixed on the body horizontally perpendicular to the wall. The pump is fixed in such a way that the delivery tube and the paste-releaser of the pump are leading outside to deliver the toothpaste onto the toothbrush.

Patent CA-2431500-A1 (CA)
Inventor: TOES RENE EVERARDUS MARIA
IPC: A61K38/095
Filed: 2001-12-07
Abstract: The invention is concerned with epitopes derived from human papilloma virus, and peptides having a size of about 22-45 amino acid residues comprising minimal T cell epitopes. The invention further provides clinically relevant approaches for immunizing subjects against (Myco)bacterially and/or virally infected cells or tumor cells, and in particular against HPV. The invention demonstrates that peptide sequences of 22-35 amino acid residues in length can induce both peptide-specific CD8+ cytolytic cells and CD4+ T-helper cells.  Moreover, the invention demonstrates that vaccination with 22-35 residue long peptides results in a more vigorous CD8+ cytolytic T-cell response than vaccination with peptides of the exact minimal CTL epitope length. The invention further demonstrates that the intrinsic capacity of certain minimal CTL epitopes which instead of activating cytolytic effector cells tolerize these cytolytic cells, can be overcome by use of these 22-35 amino acid long peptides. The invention further provides clinically relevant approaches for vaccination and/or treatment of subjects against HPV. The invention also provides methods and uses suited to treat subjects suffering from progressive lesions and/or cervical cancer.

Abstract: An approach for caching an electronic product (2) generally involves the use of confirmation data (3) that indicates that an electronic product (2) was successfully provided from a cache (204) to a user (202). In response to receiving a request (1) to provide an electronic product (2) to a user (202), the cache (204) provides the electronic product (2) to the user (202). If the electronic product (2) was successfully provided by the cache (204) to the user (202), then the cache (204) generates confirmation data (3) that indicates that the electronic product (2) was successfully provided by the cache (204) to the user (202). The cache (204) may also provide the confirmation data (3) to a confirmation recipient (206). The confirmation data (3) may also specify other information, such as an identity of the user, a location of the user and/or a time at which the cache provided the electronic product to the user.

IPC: G01N21/59
Filed: 2003-10-17
Abstract: A method for analyzing a dispersion such as an oil/solid suspension or an oil/water emulsion. A set of original domain data is collected relating to an attribute of the dispersion, such as light transmittance therethrough. The set of original domain data is then transformed into a transformed set of original domain data which is in the frequency domain. Any transformation technique, such as a fast Fourier transform, may be used to transform the original domain data from a first domain, such as a time or spatial domain, into the frequency domain. The dispersion is then characterized using the transformed set of original domain data. One or more frequency domain spectra may be generated from the transformed set of original domain data, which frequency domain spectra express a parameter relating to the attribute of the dispersion as a function of frequency, in which case the characterizing step may be performed using the frequency domain spectra.
