Abstract: An improved conical keratometer (10) wherein the parent image of the pattern to be reflected upon a target positioned adjacent to the illuminated bore is recorded on a film slide (40) retained within the keratometer bore (12). Opposite edges (51, 52) of the slide (40) are chamfered at equal but opposite angles so that, when the spindeled slide is released) the chamfered edges (51, 52) will meet along a line of contact rather than butting squarely together. The film slide (40) is rolled so that the emulsion side (53) is toward the periphery of the cone bore (12) and the chamfering allows that side to lie smoothly against the cone bore (12) without any gaps so that an undistorted image may reliably be reflected upon a standard target.

Title: Condensation polymer of an aromatic sulfonic acid and an aldehyde for inhibiting hiv infectivity
Inventor: SINGH SHYAM K
IPC: A61K31/795
Filed: 1994-11-17
Granted: 2007-09-25
Abstract: This invention pertains to the discovery that condensation polymers of an aldehyde and aromatic sulfonic acids and fractions thereof, such as formaldehyde naphthalenesulfonic acid condensation polymers, can abrogate HIV gp120 binding to CD4, as demonstrated in CD4/gp120 binding assays. In addition to gp120 binding inhibition, the compounds have been shown to inhibit HIV-induced syncytia formation and infectivity of CD4 cells. The use of this compound has been shown to be non-cytotoxic and non-inhibitory to antigen induced T lymphocyte proliferation. Based on these findings, these compounds can be used as a therapeutic agent for the treatment of acquired immunodeficiency syndrome (AIDS), as well as AIDS-related complex (ARC), AIDS-related dementia and non-symptomatic HIV infection. The compounds can also be used to treat blood preparations.

Abstract: L'invention se rapporte à un appareil et à un procédé consistant à utiliser une cuve remplie d'eau pourvue de deux sections verticales et de deux sections horizontales qui réunissent les extrémités supérieures et inférieures des sections verticales. Une dent de pignon est montée rotative avec un arbre de sortie horizontal dans une des sections horizontales, et une poulie mobile est montée rotative dans l'autre section horizontale. Une chaîne d'entraînement sans fin supportant une pluralité de réceptacles de gaz ou godets entoure la dent de pignon et la roue mobile à l'intérieur de la cuve. Une admission de gaz est positionnée au fond de la cuve de sorte qu'une partie de gaz pénétrant dans la cuve entre par les extrémités ouvertes des godets orientés vers le bas et fait sortir par pression une partie de l'eau des godets. La pression hydrostatique de l'eau exerce une force montante sur le gaz contenu dans le godet, déplaçant ainsi le godet vers le haut. La pression hydrostatique de l'eau diminue au fur et à mesure que le godet se déplace vers le haut, provoquant parallèlement une réduction de pression du gaz jusqu'à ce que la pression du gaz soit réduite, à la surface, grâce à la pression hydrostatique de l'eau au niveau de l'admission du gaz dans la cuve. Le déplacement des godets vers le haut fait tourner la dent de pignon et l'arbre de sortie, l'énergie ainsi produite étant destinée à être utilisée à l'extérieur de la cuve et la pression du gaz étant réduite.

Abstract: La présente invention à trait à un procédé et un appareil permettant de détecter optiquement un mouvement transitoire à la surface d'un objet. On dirige un faisceau laser vers la surface d'un objet, la surface de l'objet reflète le faisceau laser qui va ensuite pertuber, à l'intérieur d'un matériau holographique en temps réel, un faisceau pompe extrait de la source laser de maniêre à former un réseau de diffraction qui diffracte le faisceau pompe en un faisceau de référence, lequel perturbe, à la sortie du matériau holographique en temps réel, le faisceau de lumière reçu et produit de la sorte un signal représentatif du mouvement transitoire à la surface de l'objet. On applique au matériau holographqiue un champ électrique d'une amplitude suffisante pour augmenter de manière significative l'intensité dudit faisceau de référence et lui conférer une phase sensiblement différente de celle du faisceau de lumière reçu. Le champ électrique est appliqué avant que soit induit le mouvement transitoire devant être détecté, pendant un intervalle de temps suffisamment long pour permettre de capter le mouvement transitoire mais suffisamment court pour éviter le réchauffement excessif du matériau holographique en temps réel. Le faisceau pompe est d'une intensité suffisamment élevée pour que le temps de réponse du matériau holographique en temps réel soit sensiblement plus court qu'une durée caractéristique définie comme le temps durant lequel la phase de la lumière reçue, en moyenne dans sa répartition spatiale ou localement, ne subit pas de modification sensible.

Granted: 2004-05-04
Abstract: An improved tibial prosthesis (10) is provided for a prosthetic knee wherein the tibial prosthesis includes a mobile bearing member designed to better accommodate a natural range of flex knee motions and force loads applied to the knee joint. The improved tibial prosthesis comprises a tibial component (12) defining a support tray (16) for receiving and supporting a bearing member (14) which in turn defines upwardly presented medial and lateral condylar recesses (22, 24) for respective seated engagement with medial and lateral condyles of a femoral prosthesis. A short lock rim (26) of part-circular shape projects upwardly from the periphery of the tibial support tray (16), at the medial end thereof, to engage and constrain the bearing member (14) for rotation within the lock rim (26) through a short arcuate path of motion relative to a center axis defined by the geometry of the lock rim (26), thereby permitting a small degree of anterior/posterior movement of the bearing member (14) lateral end relative to the tibial tray (16). The range of permissible bearing member displacement can be limited by a stop post (32) projecting upwardly from the tibial tray and received into an elongated guide slot (34) formed in the bearing member.
