Patent MX-PA04006665-A (MX)
Title: Tapered lens having increased forward light intensity and light curing devices and kits incorporating such lenses.
Inventor: VASILIY NOSOV
IPC: G02B7/02
Filed: 2003-01-07
Abstract: The invention is directed to lenses (20) having thin walls and a generally conical shape for use with dental light curing devices. The conical or otherwise tapered shape enables the apex (26) of the lenses to be inserted at least partially within a dental preparation (e.g. a Class II dental preparation). The thin walls (28) allow the light emitted from the light curing device to pass through the lens (20) and apex (6) without being undesirably refracted, thereby enabling light to be emitted directly in front of the apex (26) with sufficient intensity to cure light-curable compounds within the dental preparation.
Patent MX-PA04007757-A (MX)
Title: Crash attenuator with cable and cylinder arrangement for decelerating vehicles.
Inventor: KELLY R STRONG
IPC: E01F15/14
Filed: 2004-08-11
Abstract: An improved crash attenuator that uses a cable and shock arresting cylinder arrangement to control the rate at which a vehicle impacting the crash attenuator is decelerated to a safe stop is disclosed. The crash attenuator is comprised of a front section and a plurality of mobile sections with overlapping angular corrugated side panels. When the crash attenuator is impacted by a vehicle, the front section and mobile sections telescope down in response, and thus, are effectively longitudinally collapsed. For this purpose, the sections are slidably mounted on at least one guiderail that is attached to the ground. Positioned preferably between two guiderails is the cable and cylinder arrangement that exerts a force on the front section to resist the backward movement of the front section when struck by an impacting vehicle using a varying restraining force to control the rate at which an impacting vehicle is decelerated to safely stop the vehicle. The side panels can also be used in a gu ardrail configuration. A variety of transition arrangements to provide a smooth continuation from the crash attenuator to a fixed obstacle protected by the crash attenuator.

Patent MX-PA05010920-A (MX)
Title: Device for treating back pain by re-establishing the exchange of nutrient & waste.
Inventor: YEUNG TERESA T
IPC: A61L31/00
Filed: 2004-05-07
Abstract: The intervertebral disc is avascular. With aging, endplates become occluded by calcified layers, and diffusion of nutrients and oxygen into the disc diminishes. The disc degenerates, and pain ensues. Conduits are delivered and deployed into the intervertebral disc to reestablish the exchange of nutrients and waste between the disc and bodily circulation to stop or reverse disc degeneration and relieve pain. The intervertebral disc installed with semi-permeable conduits may be used as an immuno-isolated capsule to encapsulate donor cells capable of biosynthesizing therapeutic molecules. The semi-permeable conduits establish the exchange of nutrients and therapeutic molecules between disc and bodily circulation to treat a disease without using immunosuppressive drugs.

Patent MX-PA06001602-A (MX)
Title: Cold pack.
Inventor: PURCELL RICKY W
IPC: A61B10/00
Filed: 2004-03-31
Abstract: A cold pack (10, 20, 30) that includes an enclosure (11, 21, 31) having a powdered solute (12, 22, 32) and a liquid (14, 24, 34) sealed inside the enclosure. The powdered solute and the liquid are segregated within the enclosure by a membrane (16, 26, 36). Rupturing the membrane mixes the liquid with the powdered solute to produce an endothermic solution within the enclosure. Substantially all of the powdered solute rapidly dissolves within the liquid such that the cold pack quickly reaches its cooling temperature. In another aspect, the cold pack includes an absorbent core (27, 37) within the enclosure. The absorbent core retains the endothermic solution such that the absorbent core spreads the endothermic solution throughout the enclosure. Spreading the endothermic solution (28, 38) throughout the enclosure produces a uniform cooling temperature throughout the cold pack.

Title: Immunising against meningococcal serogroup y using proteins.
Inventor: CONTORNI MARIO
IPC: A61K39/095
Filed: 2005-04-22
Abstract: The established dogma for meningococcus is thus that immunisation against serogroups A, C, W135 and Y shall be based on the four different capsular saccharides, and that immunisation against serogroup B shall not be based on the capsular saccharide. In contrast, the invention uses polypeptide antigens and/or OMVs to immunise against serogroups A, C, W135 and Y (and against serogroup Y in particular). Serogroup B polypeptides can achieve this protection, thus permitting a single polypeptide-based vaccine to be used for protecting against all of serogroups A, B, C, W 135 and Y.
