Title: Macroporous chitosan beads and preparation method thereof
Inventor: CHOI KUIWON
IPC: C08B37/08
Filed: 2000-11-30
Abstract: The present invention relates to macroporous chitosan beads having 5-200 µm in size of relatively large and uniform pores that are distributed from surface to core region, and a preparation method thereof comprising the following steps: by dropping chitosan solution, aqueous chitosan solution or their mixture into the low-temperature of organic solvent or liquid nitrogen;  and by regulating pore size by phase separation method via temperature difference. The macroporous chitosan beads of the present invention make cell culture more efficient than the previous substrate, since cell can attach to them efficiently due to their large surface area, it is easy for cell to be injected into them and cell attached to them can exist longer due to their three-dimensional structure, therefore they can be used for a study about production of protein, antibiotics, anticancer agent, polysaccharide, physiologically active agent, animal hormone, or plant hormone as well as a study about substitution of metabolic organs, cartilage or bone.

Title: Collection shortcut reference expander
Inventor: JAMESON KEVIN W
IPC: G06F17/30
Filed: 2002-08-27
Abstract: A Collection Shortcut Expander method expands shortcut collection reference expressions into complete reference expressions, thereby improving the productivity of people who work with collections. In operation, a Collection Shortcut Expander receives expansion requests from request originators, expands shortcut collection reference expressions into complete collection reference expressions, and returns expanded references to the request originators. Shortcut references to local collections are expanded using information from a curren t collection specifier file. Shortcut references to remote collections are expanded using informati on from a knowledge base. Collection Shortcut Expanders improve human productivity by providing convenient syntaxes, by reducing typing burdens, by reducing knowledge burdens, by reducing human retraining costs caused by collection name changes, and by enabling people t o create customized alias names for frequently used collection names.

Title: Low dose haptenized tumor cell and tumor cell extract immunotherapy
Inventor: BERD DAVID
IPC: A61P35/00
Filed: 2001-02-02
Abstract: This invention relates to compositions comprising haptenized tumor cells and extracts thereof, methods for preparing the compositions, vaccines comprising such haptenized tumor cells, and methods for treating cancer with such vaccines. In a specific embodiment, melanoma cells are haptenized with a dinitrophenyl group, and used for treatment of melanoma patients having metastatic disease. Preferably, patients are given a first vaccine dose containing haptenized cells to "prime" the immune system.

Title: New prostate cell lines
Inventor: THRAVES PETER
IPC: A61P35/00
Filed: 2001-03-30
Abstract: An increasingly aged population and better diagnosis has lead to an apparent  increase in the prevalence of prostate cancer in men. There is an acute need  to better understand the progression of this disease from its locally confin ed site of initiation to the end stage widely metastatic disease with attendant  morbidity and mortality. It has historically been difficult to raise and maintain immortalised prostate cell lines in culture. We have derived a cell  line selected from the group consisting of clones ONYCAP 1 and ONYCAP23. The  cell lines are characterised as being prostate epithelial in origin.

IPC: B60S9/08
Filed: 2001-04-09
Abstract: Les mécanismes à vérin de dispositifs d'appui pour des remorques de véhicules articulés sont souvent laissés en position neutre lorsque le véhicule tracteur roule. En raison des vibrations qui se produisent pendant que le véhicule roule, le mécanisme d'appui à vérin peut se détacher de manière non intentionnelle, toucher le sol et se trouver ainsi endommagé. Dans le dispositif d'appui à mécanisme à vérin selon la présente invention, le vérin d'appui est fiablement attaché et ne peut se détacher. A cet effet, la couronne dentée de l'arbre d'entrée (1) possède deux segments longitudinaux (1a, 1b) de diamètre différent, la répartition des dents étant la même sur ces deux segments. La longueur des dents sur ces deux segments (1a, 1b) est ainsi mesurée que l'arbre d'entrée (1) peut tourner, dans la position neutre, alors que la roue dentée (3a) est stationnaire, mais que ladite roue dentée (3a) ne peut tourner lorsque l'arbre d'entrée (1) est stationnaire.

Title: Micromachined silicon gyro using tuned accelerometer
Inventor: STEWART ROBERT E
IPC: G01C19/56
Filed: 2001-10-11
Abstract: A micromachined silicon tuned accelerometer gyro is formed out of silicon wafers, by micromachining. The top and bottom cover which include driver, forcer, tuning and guard ring elements mounted therein are micromachined in arrays on silicon-on-insulator (SOI) wafers. The center (driver and sensing) element between the top and bottom is micromachined in an array of four inch diameter silicon wafers. The driver and sensing structure is a tuned pendulum attached by flexure joints to a vibrating structure which is suspended by a parallelogram dither suspension. The pendulum is tuned by adjusting the magnitude of a d.c. signal to match the natural frequency of the pendulum to the natural frequency of the vibrating structure. The dither suspension flexures of the vibrating structure is uniquely defined and easily machined but yet provides a dither suspension that restrains the vibrating structure within its vibrating plane with no harmonic distortion.
