Patent CA-2345817-A1 (CA)
Inventor: KARLSSON GUNILLA
IPC: A61P15/00
Filed: 1999-10-05
Abstract: A method is disclosed for inducing cell-mediated immunity against cellular antigens. More specifically, the invention provides for a method for inducing cytotoxic T-lymphocyte immunity against weak antigens, notably self-proteins.  The method entails that antigen presenting cells are induced to present at least one CTL epitope of the weak antigen and at the same time presenting at least one foreign T-helper lymphocyte epitope. In a preferred embodiment, the antigen is a cancer specific antigen, e.g. PSM, Her2, or FGF8b. The method can be exercised by using traditional polypeptide vaccination, but also by using live attenuated vaccines or nucleic acid vaccination. The invention furthermore provides immunogenic analogues of PSM, Her2 and FGF8b, as well as nucleic acid molecules encoding these analogues. Also vectors and transformed cells are disclosed. The invention also provides for a method for identification of immunogenic analogues of weak or non-immunogenic antigens.

Filed: 2001-05-04
Abstract: Snowplow blade extensions for two conventional snowplows to remove snow and/or ice in forward and rearward directions. One embodiment comprises a forward rectangular blade having a rear rectangular blade attached to its rear face at an acute angle by spaced gussets to form two legs with bevelled bottom edges. The upper portion of the forward rectangular blade is bolted on the bottom front face of the snowplow blade. The other embodiment utilizes a pair of brackets on the rear of the snowplow blade to hang the rearward extension blade and cooperate with the existing forward extension blade at the bottom edge of the forward face of the snowplow blade to form an inverted V formation of two legs with bevelled edges contacting the ground surface to be cleared of snow and/or ice in both forward and rearward directions.

Title: Incorporating shared randomness into distributed cryptography
Inventor: FRANKEL YAIR
IPC: G09C1/00
Filed: 1999-10-29
Abstract: A method of distributed cryptography for high consequence security systems which employs randomness between operating parties. Shared randomness is accomplished by sharing cryptographic keys stored in secure hardware tokens by potentially less secure software or general purpose computing units that perform distributed cryptography. The shared randomness is based on shared keys (at the tokens) and unique context. Shared random values are incorporat ed into the computation of partial results used in the distributed cryptographi c calculation. The incorporation of shared randomness provides a hand-shake among the hardware tokens. When the operation is successful, a result is computed with assurance that the correct parties have taken part in forming the result. The hand-shake assures binding of operating parties and added system security.

Title: Assay for anti transglutaminase antibodies
Inventor: SORELL GOMEZ LUIS TOMAS
IPC: G01N33/53
Filed: 2001-05-31
Abstract: A non-instrumental assay for the diagnosis of celiac disease based on the general immunochromatographic assay principles. The assay is rapid and simple and allows the reliable detection of anti transglutaminase antibodies, of both IgA and IgG isotype, in samples of human serum, plasma or blood, using as tracer the antigen transglutaminase conjugated to a colored substance, like colloidal gold or colored latex particles. The conjugated antigen is deposited onto an inert fibrous support, from where it can be released by a liquid sample. The antibodies in the sample react with the conjugated antigen developing an immunocomplex that migrates through a carrier membrane, like nitrocellulose or nylon with a pore size that allows a laminar flow of the reagents, until it reacts with the same antigen transglutaminase immobilized onto a reactive zone of the membrane. As a consequence of this reaction the immunocomplex will be trapped in the reaction site and a colored signal will be seen. Therefore a visually detectable signal in the reactive zone of the membrane indicates a positive result for the detection of anti transglutaminase antibodies in the sample.

Inventor: YOSHIDA HIROSHI
IPC: H01M50/133
Filed: 2001-08-30
Abstract: A lithium based battery includes a cell structure group formed by stacking unit cells each including a positive electrode, a negative electrode, and a separator interposed therebetween, or formed by repeatedly folding or winding an integral body of the unit cells; a battery container for containing the cell structure group; and an electrolyte, which is poured in the battery container after the cell structure group is contained in the battery container. The outer peripheral surface of the battery container is covered with an ion impermeable and extensible high polymer sheet having a tensile elongation percentage of 1 % or more. With this configuration, even if there happens such a severe accident that nail pieces the battery or the battery is crashed, it is possible to prevent a large short-circuit current from flowing between the positive and negative electrodes, and hence to ensure a higher safety of the battery.

IPC: B30B1/18
Filed: 2001-12-04
Abstract: A mechanical press drive that uses a ballscrew apparatus to move the upper platen of a press upward and downward. A first coupling is connected to a screw of the ballscrew apparatus and connects the screw to one of a movable platen of a press or a stationary member of the press. A second coupling is connected to and couples a nut of the ballscrew apparatus to the other of the platen and the stationary member of the press. A drive motor is operably connected to one of the nut and screw and relatively rotates them to impart reciprocal motion to a movable press platen coupled to the other of the nut and screw. The two couplings cooperatively isolate the ballscrew apparatus from offset and moment loading that may occur during press operation.

Inventor: GREGEL JOHN J
IPC: E04G21/12
Filed: 2002-01-21
Abstract: A high strength reinforcing bar splice uses a contractible jaw assembly bridging the bar ends to be joined. The jaw assembly includes interior teeth designed to bite into the projecting ribs or deformations on the outside of the bar ends which form the overall diameter of the bar but not the core or nominal diameter of the bar. The jaw assembly is constricted from both axial ends by driving tapered locking collars on each end of the jaw assembly with a toot while concurrently causing the jaw assembly to constrict and bite into the bar ends. When the tool is removed, the collars remain in place locking the jaw assembly closed. The splice provides not only high tensile and compressive strengths but also has good fatigue and dynamic strength to qualify as a Type 2 coupler.

Title: Graphical objects with minimum and preferred sizes
Inventor: HOLLINGSWORTH DAVID E
IPC: G06F3/0484
Filed: 2000-07-19
Abstract: (57) Abstract: To process the layout of graphical objects, elastic data structures are established for the graphical objects to define minimum and preferred sizes, stretch properties and compression properties.      One application of elastics is with respect to text blocks where preferred width and compressibility of each text block is a function of the amount of text in the text block.     Composite graphical objects include elastic properties computed from their components through add and max operations which are dependent on relative elasticities of the components. The positions of origins within graphical objects are defined by pairs of elastics in each of two dimensions. The default width or height preference of a graphic object can be overridden. Overriding elastics is an effective mechanism for altering the display characteristics of graphical objects while preserving certain display relationships. The elastics and dimensions of graphical objects are processed in a three pass layout negotiation. In the first pass, preferred sizes and elasticities of the graphical objects are computed along a first dimension. In a second pass, size values of the graphical objects along the first dimension are computed from the preferred sizes and elasticities, and preferred sizes and elasticities of the graphical objects along a second dimension are computed based on the size values of the graphical objects along the first dimension. In a final pass, size values of the graphical objects along the second dimension are computed from the preferred sizes and elasticities.
