Inventor: CHU MAY-YING
IPC: H01M10/39
Filed: 1998-10-06
Abstract: Disclosed are electrolyte solvents for ambient-temperature lithium-sulfur batteries. The disclosed solvents include at least one ethoxy repeating unit compound of the general formula R1(CH2CH2O)nR2, where n ranges between 2 and 10 and R1 and R2 are different or identical alkyl or alkoxy groups (including substituted alkyl or alkoxy groups). Alternatively, R1 and R2 may together with (CH2CH2O)n form a closed ring. Examples of linear solvents include the glymes (CH3O(CH2CH2)nCH3). Some electrolyte solvents include a donor or acceptor solvent in addition to an ethoxy compound as described. Examples of donor solvents include hexamethylphosphoramide, pyridine, N,N-diethylacetamide, N,N-diethylformamide, dimethylsulfoxide, tetramethylurea, N,N-dimethylacetamide, N,N-dimethylformamide, tributylphosphate, trimethylphosphate, N,N,N',N'-tetraethylsulfamide, tetramethylenediamine, tetramethylpropylenediamine, and pentamethyldiethylenetriamine. These assist in solvation of lithium ions. Examples of acceptor solvents include alcohols, glycols, and polyglycols. These assist in solvation of the sulfide and polysulfide anions.

Filed: 1999-08-02
Abstract: There is provided a glycosaminoglycan having a backbone structure comprising a repetitive disaccharide bearing a uronic acid residue and a glucosamine residue, and having sulfate groups, wherein substantially no sulfate group bound to the hydroxyl group at the 6--position of the glucosamine residue in the backbone structure is detected as determined by a chemical disaccharide analysis method in which the glycosaminoglycan is decomposed with nitrous acid, reacted with para-nitrophenylhydrazine and analyzed by high performance liquid chromatography, and the molar %  of a uronic acid residue having a sulfate group at the 2-position is not less than 45% relative to total uronic acid residues, which is calculated from a disaccharide composition obtained by an enzymatic disaccharide analysis method in which the glycosaminoglycan is digested with glycosaminoglycan-degrading enzymes and analyzed by high performance liquid chromatography. The glycosaminoglycan can be used as an active ingredient of phamaceuticals.

Patent CA-2319248-A1 (CA)
Inventor: ARMINI ANTHONY J
IPC: C23C14/58
Filed: 1999-02-08
Abstract: Past techniques utilized wet chemistry to produce a carrier-free radioisotope for a seed implant. However, by using the technique of ion implantation, it is possible to physically separate the precursor isotope by magnetic means and further, to physically direct a beam of these isotopically pure atoms and to embed them into a suitable carrier body. Thus, formation of the seed implant may be accomplished using dry techniques, that is, no liquid chemistry. The systems and methods disclosed herein are designed to produce a beam of a single stable isotope using an ion implanter and to further implant this single stable isotope below the surface of a carrier body. After neutron activation, these single stable isotopes will produce the isotopes iodine-125, palladium-103, cesium-131, or ytterbium-169 embedded within the carrier body. Optionally, the carrier body may be encapsulated prior to activating the precursor isotope embedded in the carrier body.

Title: Device for compressing a load of particulate material
Inventor: BODECKER THOMAS F
IPC: B30B9/30
Filed: 2000-12-27
Abstract: The device for compressing a load of particulate material in an open-top trailer includes a frame mounted or mountable on a support so as to be elevated over the load of particulate material in the open-top trailer, a drum roller rotatably mounted or mountable to the frame, and a windrower mounted or mountable to the frame adjacent the drum roller. The windrower is for windrowing a heaped portion of the load of particulate material so as to heap the heaped portion above upper edges of sides of the trailer. The windrower windrows the heaped portion into a windrow of particulate material generally centrally aligned with a longitudinal axis of the trailer as the trailer and the windrower are translated relative to one another along the longitudinal axis. The drum roller is disposed on the frame so as to roll over and thereby compress the windrow of particulate material as the trailer and the roller translate relative to one another along the longitudinal axis.
Patent CA-2329875-A1 (CA)
Title: Matrices formed of polymer and hydrophobic compounds for use in drug delivery
Inventor: BERNSTEIN HOWARD
IPC: A61K9/22
Filed: 1999-03-08
Abstract: A lipid or other hydrophobic or amphiphilic compound (collectively referred to herein as "hydrophobic compounds") is integrated into a polymeric matrix for drug delivery to alter drug release kinetics. In embodiments where the drug is water soluble, the drug is released over longer periods of time as compared to release from the polymeric matrix not incorporating the hydrophobic compound into the polymeric material. In contrast to methods in which a surfactant or lipid is added as an excipient, the hydrophobic compound is actually integrated into the polymeric matrix, thereby modifying the diffusion of water into the microparticle and diffusion of solubilized drug out of the matrix.  The integrated hydrophobic compound also prolongs degradation of hydrolytically unstable polymers forming the matrix, further delaying release of encapsulated drug.

Title: Radio frequency identification device and method of use
Inventor: LAWLER CASIMIR E
IPC: A22B7/00
Filed: 1999-05-18
Abstract: In the inventive method for the sanitary rinsing of an animal, an assembly line is provided which includes a plurality of shackles.  Each shackle includes an inventive RFID tag which includes a machine readable unique shackle number. Once an animal is stunned and attached to a shackle the animal is moved to a weighing station, which is equipped with an RFID tag reader, weighs the animal and transmits the weight and shackle number to a computer where the data is recorded in a database. The animal is then bled and moved to a rinsing station, which is equipped with an RFID tag reader which reads the shackle number. The system then looks up the weight of the animal to be rinsed at that particular rinsing station and calculates the amount of solution to inject into the circulatory system of the animal. After the end of the hose and nozzle and the operator's hands are sanitized, which is verified by the system, the nozzle is inserted into an entry point into the circulatory system and the operator starts the flow of the predetermined amount of solution into the animal. If the flow is not started within a time window, the operator must resanitize.

Title: Screening device and method of screening an immunoassay test
Inventor: BALDWIN DENE
IPC: G01N33/53
Filed: 1999-07-14
Abstract: Immunoassay tests run on samples of body fluid may be screened in the screening device and the lines formed by the immunoassay testing are interpreted to detect the presence of particular compounds such as drugs in the body. Light from an LED 44 is shone onto the window of an immunoassay test cartridge 10 illuminating a test membrane. Light reflected from the membrane 24 is reflected by a mirror 40 into the field of view of a charge coupled device 34. The image is digitised and outputted by video data interface to a CPU 80 for data processing. The digitised data is segmented according to preset data defining control regions test regions and background regions on the test membrane. The segmented data for the test region is compared to the data from the control region and the background regions to determine whether the test data exhibits any significant results compared to the control region and background regions. The results of the comparison are outputted to a liquid crystal display. The results may be displayed as either positive or negative for any particular substance or the concentration of the particular substance may be displayed. The screening device incorporates a timer which is activated when an immunoassay test cartridge is inserted into the device to ensure that an appropriate delay occurs to allow the immunoassay test to run correctly.
