Patent CA-2432527-A1 (CA)
Title: Medicinal compositions for oral use
Inventor: AKIYAMA YOHKO
IPC: A61K31/445
Filed: 2001-12-21
Abstract: Medicinal compositions for oral use characterized by comprising a compound having a CCR5 antagonism which has been dissolved or dispersed in an amphiphilic carrier. Because of having an extremely high oral absorbability while showing little scatter in the concentration of the CCR5 antagonistic compound or its salt in blood, these compositions are usable as preparations  for oral administration which are efficacious in preventing and treating various HIV infections in humans.
Patent CA-2434882-A1 (CA)
Title: Method and device for generating and/or decoding a scalable data stream with provision for a bit savings bank, encoder and scalable encoder
Inventor: SPERSCHNEIDER RALPH
IPC: G10L19/14
Filed: 2002-01-14
Abstract: In a method for generating a scalable data stream, when a block (11) of output data of a first encoder is present, this block of output data is written into the scalable data stream. If output data (0) of a second encoder is present for a preceding period of time, this output data for the preceding section is written in transmission direction behind the block (11) of output data of the first encoder into the data stream. When the output data (1) of the scalable encoder for the current section is present, the output data of the second encoder is written into the bit stream subsequent to the output data of the first encoder. A determining data block (200) is generated and written into the bit stream delayed by a period of time (250) which corresponds to the size of the bit savings bank of the second encoder. Finally, buffer information (260) is written into the bit stream, which indicates, where the beginning of the output data of the second encoder for the current section regarding the determining data block is, wherein the buffer information (260) corresponds to the bit savings bank level. Thus, it is possible to simply signalize a bit savings bank in a scalable data stream. The maximum size of the bit savings bank may further be adjusted depending on the intended decoder delay and be communicated to a decoder by positioning the determining data block in the scalable data stream without an effort of additional bits in order to reduce the initial delay of the decoder.

Title: Automated fabrication of an integral fiber reinforced composite structural component using a positioning and assembly support
Inventor: PABSCH ARNO
IPC: B29C70/48
Filed: 2003-08-08
Abstract: A forming jig includes a grid pattern of support walls arranged on a support base and having upper free ends located along an imaginary curved surface, and modular sectional profile members arranged on the walls to enclose a vacuum chamber within the jig. Grooves, channels and air passages between neighboring profile members communicate into the vacuum chamber. The outer surface of the profile members matches the intended inner surface of a structural component to be fabricated using the jig. In the fabrication process, a film is applied to the outer surface to pre-establish a vacuum, the film is removed while simultaneously a vacuum skin is applied, stringer members are set into the grooves, fiber skin layers are laid up, a sealant is applied around the perimeter, a structural shell is vacuumed onto the skin layers, and then this preformed component is removed from the jig, injected with resin unless the skin layers were pre-impregnated with resin, and cured.

Patent CA-2450477-A1 (CA)
Inventor: LEPOSAVIC NATALIA
IPC: B65D23/12
Filed: 2003-11-18
Abstract: Bottle (10) having an improved bottle wall (11) capable to hold its reusable stopper (14) while keeping bottle's upright stability. The bottle walls are forming bay with cup like seat that holds stopper in place using elastic properties of plastic materials used for bottle and stopper, and friction between surfaces of bottle and stopper.   The bay has a shallow and wide entry (17) on the top. From the entry point, going down, the bay gains depth and becomes narrower towards the low bay point, so stopper (14) can find its way into the cup-like seat easily. After the wide entry, stopper's circumference is getting in touch with the inner walls of the recess (15) that are from that point gently conical. With further travel of stopper, until it is completely positioned within the bay, the holding of a stopper is achieved by elastic deformation and friction between stopper (14) and bottle's recessed walls (15. Conical walls at the bay bottom may be slightly widened (relaxed) so "click" sensation is achieved when stopper slides in.. This shape provides easy placing of stopper in the recessed wall (bay) from the top and room for fingers at low point (16) to take the stopper out.
