Title: Femoral component for knee endoprosthesis
Inventor: PAPPAS MICHAEL J
IPC: A61F2/38
Filed: 1999-02-08
Abstract: A femoral component of a knee prosthesis includes a bearing surface defined by a smooth, continuous surface which in one embodiment is entirely formed by a series of three segments of surfaces of revolution, the respective shapes of which are generated by rotating a common generating curve around three separate generating axes at respective pairs of major generating radii and through respective angles of rotation. The central segment of the surfaces of revolution constantly maintains the substantially same contact configuration with the superior bearing surface of a bearing insert over a range extending from full extension (0° of flexion) to at least 45° of flexion and up to 105° of flexion. The maintenance of the substantially same contact configuration ensures area, point or line contact between the articulating surfaces which reduces contact stress and wear in flexion. In a second embodiment, the bearing surface is defined by four segments of surfaces of revolution shaped for implantation in a knee where one or both cruciate ligaments are retained.

Abstract: A sundial consists of a gnomon which serves to cast a shadow, and a face on which the shadow is cast, which is marked so that when the sundial is illuminated by sunlight, the position of the shadow indicates the time. In a conventional sundial, the face has a curve with times marked on it, and the gnomon casts a shadow which has a straight edge so that the time is indicated by the position on the curve where the curve is crossed by the straight edge of the shadow. Such a sundial indicates time in solar time so that to ascertain the time in standard time, it is necessary to add to or subtract from the solar time a correction amount which varies throughout the year. This invention is a sundial in which the part of the gnomon's shadow that indicates the time is not an edge but a single point, and every point on the face indicates a time instead of just points on one curve. The face of this invention ca.n be marked so that it indicates the time accurately in standard time. I call this invention a Fixed-Gnomon Standard-Time Sundial.

Title: Novel method and apparatus for traffic shaping in a broadband fiber-based access system
Inventor: GRAVES ALAN FRANK
IPC: H04L69/14
Filed: 1999-05-20
Abstract: A novel method and apparatus for controlling the flow of traffic between a host digital terminal (HDT) and a plurality of optical network units (ONU s). Each ONU is connected to the HDT by optical fiber and to a plurality of subscribers by a respective plurality of subscriber drops. The bandwidth on the fiber, although large, is usually inferior to the total bandwidth that can be transmitted across the subscriber drops. Therefore, both upstream and downstream traffic may become congested at various "choke points" under certain circumstances of usage. The present invention provides a traffic shaper located in the HDT, which gives centralized control of the traffic flowing to and from the ONU s. Consideration of the priority and destination of each traffic cell is taken into account by the traffic shaper to ensure that the capacity of the fiber and of the individual drops is never exceeded, irrespective of the transaction sizes, thereby eliminating the need for costly buffers in the outside plant. Any maintenance or repairs of the traffic shaper can be easily effected without field visits, due to its centralized location.
Patent CA-2274715-A1 (CA)
Title: Procede et dispositif pour l'attribution variable de spectres de communication d'amont et d'aval
Inventor: FURUKAWA NEIL E
IPC: H04L5/14
Filed: 1997-12-24
Abstract: L'invention concerne un émetteur-récepteur numérique amélioré de communication bidirectionnelle dans lequel les parties en amont (24) et en aval (22) du spectre de fréquences sont allouées à différentes largeurs de bandes et disposées à différents emplacements sur le spectre de fréquences en fonction des conditions de la ligne de transmission et des dégradations telles que la localisation d'un système, le bruit de fond, les interférences radioélectriques, les parasites et les signaux réfléchis. Les mouvements des fréquences porteuses en amont et en aval sont élastiques caractérisés en ce qu'ils peuvent être pratiquement réglés en temps réel au moyen de procédés qui déterminent le paramètre de qualité du signal (SQP) du signal reçu. Le SQP sert à évaluer la marge de taux d'erreurs sur les bits (BER) des données reçues et sert aussi à tenir compte du rapport signal/interférence (SIR) total où l'interférence comprend les parasites, les interférences radioélectriques et l'écho résiduel en provenance de la voie environnante en amont (24) et en aval (22). Parce que les fréquences porteuses des voies en amont (24) et en aval (22) sont allouées de maniére dynamique, il faut mettre en place une acquisition porteuse robuste, une reconstitution et un algorithme de verrouillage. Les algorithmes porteurs robustes permettent la reconstitution des fréquences porteuses des signaux émis en amont et en aval indépendamment de leurs modulations particulières ou du débit des symboles.

Title: Control and suspension system for a covering for architectural openings
Inventor: COLSON WENDELL B
IPC: E06B9/326
Filed: 1999-06-22
Abstract: A control and suspension system for a retractable covering mounted on a rotating element includes an apparatus for mechanically limiting over-extensions of the covering and an apparatus for mechanically limiting over-retractions of the covering, The apparatus for limiting over-retraction includes a threaded shaft and an internal, roll-bar-support wheel treaded on the threaded shaft. An intercepting ledge comprising part of the internal, roll-bar-support wheel, and a stopping ledge comprising part of the threaded shaft. Over retraction of the covering is prohibited when the intercepting ledge impacts the stopping ledge. The apparatus for limiting over-extension includes a roll-bar-end support wheel having a down limit stop pivotally mounted thereto. When the covering material is fully extended, the limit stop rotates away from the roll-bar-end support wheel and impacts a substantially annular channel wall associated with an end cap, thereby preventing further rotation of the roll bar and thus further extension of the covering. The control and suspension system also includes an apparatus to compensate for any undesirable skewing of the covering that might occur. The skew adjustment apparatus includes a skew adjustment plate that is slidably mounted in channels on an end cap. A threaded skew adjustment plug is threadingly engaged with the skew adjustment plate such that rotation of the skew adjustment plug moves the skew adjustment plate. Finally, the control and suspension system also includes a bottom rail that attaches to the bottom of the covering by trapping a portion of the covering between a compression plate and a bottom plate.

Inventor: DOSOV ALEXANDER NIKOLAEVICH
IPC: E21B43/38
Filed: 1998-12-21
Abstract: The invention is referred to the oil industry and namely to methods of oilfield development through waterflood and aims at lowering the costs and raising ecological benefits of methods of near well bore area cleanup from plugging particles through their dispersion and dissolving by the impact of ultrasound in the active liquid media until the deposits turn into a thinly dispersed hydrophobic suspension with the dimensions of solid particles within 0.5-20 µm with further injection of formed suspension into the reservoir to level out injectivity profile and decrease water inflow in producing wells.     Active liquid with surface tension on the vapor contact within 20-35 mPa-sec-1 (erg/cm2), density exceeding flood water density by no less that 100 kg/m3 and viscosity equal to water phase viscosity or exceeding it by no more than 20 times is use.   The optimum parameters of ultrasound impact are selected based on the results of prior laboratory testing of ultrasound dispersed sediment that was collected form the near well bore area. The testing is performed in various active liquids that provides a thinly dispersed hydrophobic suspension with the dimensions of particles within 0.5-20 µm.   Treating the near well bore area of wells with little sediment or wells that were previously cleaned from sediment through other methods to form thinly dispersed hydrophobic suspension in the near well bore area for its later use to block highly permeable reservoir intervals in place of active liquid media a dispersion of petroleum sludge-waste is injected into the well. The sludge is previously blended with the active liquid media, volume ratio being between 1:10 and 1:5 depending on the content of solid phase in the sludge.
