Patent MX-PA02001659-A (MX)
Title: Oilymist resistant filter that has nondecreasing efficiency.
Inventor: JOHN S HUBERTY
IPC: B01D39/16
Filed: 2000-07-17
Abstract: A filter that includes a first electret filter layer through which an airstream first passes before encountering a second electret filter layer. The first filter layer exhibits nondecreasing removal efficiency and removes a majority of a challenge aerosol; whereas the second layer exhibits decreasing removal efficiency and has an initial quality factor greater than the first layer. Together, the first and second electret filter layers can provide a filter that exhibits a nondecreasing removal efficiency and a relatively low pressuredrop. The filter can provide nondecreasing removal efficiency and reduced pressure drop even though the second electret filter layer exhibits decreasing removal efficiency in contrast to the desired nondecreasing removal efficiency for the filter as a whole.

Abstract: The assembly is used for the stabilisation of two adjacent vertebral bodies (10) of the spine. It comprises two pedicle screws (1), having a threaded shaft (2) with a tapering first end (3) for introduction into the vertebral bodies (10) and a head portion (4) with a second end (5). It further comprises a flexible longitudinal fulcrum (6) with two portions (8), which can be disposed transversely to said pedicle screws (1), and fixed with its end portions (8) to the head portions (4) of said two pedicle screws (1) at a distance x from said second end. The assembly further comprises an elastic ligament (7) which can be disposed transversely to said two pedicle screws (1) and fixed to the head portions (4) of said two pedicle screws (1) at a distance ylt;x from the end portion of the fulcrum (8). By introduction of a fulcrum, lying close to the axis of flexion and extension of the spinal motion segment, the posteriorly placed ligament distracts the whole disc, and the fulcrum istself becomes a load bearing structure. This reduces the load over the disc, and makes it an even distribution of load across the end plate throughout the range of movement of the motion segment, that is allowed by the implant.

Title: Sealing apparatus having sequentially engageable seals.
Inventor: RAMSAY THOMAS W
IPC: F16J15/00
Filed: 2001-04-13
Abstract: Advantageous seal systems (1500) are provided that include a barrier member movable relative (1504) to a shaft (1550) to allow sequential engagement of resilient seal members (1506), e.g., lip seals, with the shaft. Movement of the barrier member (1504) may be effected manually or through introduction of pressurized fluid to effect piston like movement. The disclosed seal assemblies may include an automatic leak detector and may utilize such leak detection to effectuate automatic movement of the barrier member. The barrier member may be moved relative to the shaft while the shaft is in movement, e.g., rotating or reciprocating, thereby permitting seal maintenance without interruption in operation. As seal members are sequentially brought into sealing engagement with the shaft, the previously engaged seal members contribute to the sealing performance of the seal assembly, although no longer effective to establish a stand alone seal with the shaft.

Patent MX-PA03008956-A (MX)
Title: Ladle refining of steel.
Inventor: MAHAPATRA RAMA BALLAV
IPC: C21C5/34
Filed: 2002-04-02
Abstract: A steel charge and slag forming material is heated in a ladle to form molten steel covered by a slag containing silicon, manganese and calcium oxides. The steel is stirred by injection of an inert gas such as argon or nitrogen to cause silicon/manganese deoxidation and desulphurization to produce a silicon/manganese killed molten steel. Stirring of the molten steel by the inert gas injection while in contact with slag high in calcium oxide generates low free oxygen levels in the steel and desulphurization to sulphur levels below 0.009%. The slag may subsequently be thickened by lime addition to prevent reversion of sulphur back into the steel and oxygen may be injected into the steel to increase its free oxygen content to produce a steel that is readily castable in a twin roll caster.

Title: Method of clinching top and bottom ends of z-axis fibers into the respective top and bottom surfaces of a composite laminate.
Inventor: JAMES M HOOK
IPC: B29C70/08
Filed: 2002-08-02
Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure (33). The upper and lower skins (51a, 51b) and the core (22) are pulled automatically through tooling (23) where the skin material is wetted-out with resin and the entire composite laminate (33) is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine (24) that deposits "groupings of fiber filaments" at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that a extension of each "grouping of fiber filaments" remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station (39). Next the preformed composite laminate travels into a pultrusion die (26) where the extended "groupings of fiber filaments" are all bent over above the top skin and below the bottom skin producing a superior clinched Z-axis fiber reinforcement as the composite laminate continues to be pulled, catalyzed, and cured at the back section of the pultrusion die. The composite laminate continues to be pulled by grippers that then feed it into a gantry CNC machine (36, 37) that is synchronous with the pull speed of the grippers (34, 35) and where computerized machining, drilling, and cutting operations take place. This entire method is accomplished automatically without the need for human operators.

Title: Building frame structure.
Inventor: ROBERT J SIMMONS
IPC: E04B1/58
Filed: 2002-03-18
Abstract: Column, beam and cross-bracing building frame structure and methodology. The column features an assembly of plural elongate angle-iron-like components held apart by spacers which establish laterally facing recesses between spaced, confronting legs for receiving the modified, inserted ends of the central webs in beams, and the ends of cross braces. Regions of the end-to-end, vertically-stacked joinder between two columns take the forms of compact, friction-bound splices created through and with the inserted ends of beams' central webs. Columns in a frame can respond to severe loads with a certain amount of beneficial individual load-handling promoted and provided by the plural angle-iron-like components, and with modest, reversible frictionally resisted energy-dissipating longitudinal motions relative to one another. Such loading is also resisted by reversible, frictional relative motion in the splices between beams and columns. Similar friction connections are provided between cross-connected beams.
Patent MX-PA04009530-A (MX)
Title: Surgical stapling instrument incorporating a multistroke firing position indicator and retraction mechanism.
Inventor: SWAYZE JEFFREY S
IPC: A61B17/072
Filed: 2004-09-29
Abstract: A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.

Title: Synchronization system and method for audiovisual programmes, associated devices and methods.
Inventor: ALAIN MAILLARD
IPC: H04N5/00
Filed: 2003-06-27
Abstract: The present invention relates in particular to a synchronization system (5) and method. The synchronization system comprises a specification unit (1) for specifying synchronization signals associated with an audiovisual programme (15), the latter comprising an audiovisual content and control information, a recognition unit (2) for recognizing the synchronization signals in a transmitted stream carrying this programme, by recognition of at least one extracted portion of the audiovisual content, and an activation unit (3) triggering an action in case of detection of these signals. The specification unit prepares and transmits to the recognition unit recognition elements (11) making it possible to obtain this extracted portion, as well as at least one action timeout lag in case of detection of the synchronization signals. The recognition or activation unit then delays the triggering of this action according to the lag transmitted, in case of detection of the synchronization signals. In variants, the timeout lag is determined and/or the recognition elements are obtained independently of the specification unit.

Title: Multiple variants of meningococcal protein nmb1870.
Inventor: MARIAGRAZIA PIZZA
IPC: A61K39/095
Filed: 2003-11-21
Abstract: Meningococcal protein NMB 1870 has been described in the prior art. The inventors have found that NMB 1870 is an effective antigen for eliciting anti-meningococcal antibody responses, and that it is expressed across all meningococcal serogroups. Forty-two different NMB 1870 sequences have been identified, and these group into three variants. Serum raised against a given variant is bactericidal within the same variant group, but is not active against strains which express one of the other two variants i.e. there is intra-variant cross-protection, but not inter-variant cross-protection. For maximum cross-strain efficacy, therefore, the invention uses mixtures comprising different variants of NMB 1870.
