Title: Process for preparing 1-fluorinated vitamin d compounds
Inventor: ONISKO B
IPC: G06F11/18
Filed: 1979-07-24
Abstract: New fluorine-substituted vitamin D compounds, methods for preparing such compounds and new fluorinated intermediate compounds used in such methods. The fluorine-substituted vitamin D compounds of this invention are characterized by vitamin D-like activity in their ability to stimulate intestinal calcium transport and bone mobilization and in promoting the calcification of rachitic bone.

Title: Portable modular casting mold system
Inventor: MCMILLAN LARRY SCOTT
IPC: B28B17/00
Filed: 1983-07-01
Abstract: A portable modular casting mold (18) which can be assembled from individual trailerable frames (38, 46 and 48). Each of the frames forms a portion of the trailer in cooperation with wheeled units (40, 42). The portable modular casting mold (18) permits the modular casting mold casting system to be employed in relatively small constructions because the modular casting mold can be moved and reused indefinitely for later construction. Each of the frames (38, 46 and 48) supports a series of interior and exterior wall forms and ceiling forms. The orientation of the ceiling and wall forms permits a desired molded product (24) to be molded in the modular casting mold (18). A haunch seal (196) is provided for sealing between individual wall forms and ceiling forms. A corner seal (234) is provided for sealing between adjoining edges of intersecting wall forms. A haunch corner (258) joints the haunch seals (196) and the corner seals (234) when two wall forms and a ceiling form intersect. Several sill seal assemblies (156, 158 and 160) are provided for forming a seal between facing wallforms. The sill assemblies define the bottom of the wall of the molded product (24). The sill assemblies form grooves in the bottom of the walls of the molded product to permit pressurized grouting and to form a locking joint to prevent movement of the final molded product.

L'orifice forme une ouverture annulaire entre l'intérieur de la cartouche de filtrage et la cavité de liquide propre dans le couvercle hémisphérique. L'extrémité inférieure de la cartouche de filtrage est hermétiquement fixée à un manchon (41) qui entoure le fond de la conduite fixée à un manchon (41) qui entoure le fond de la conduite verticale d'évacuation. Les joints hermétiques (53 ou 56 et 43 ou 57) pour le haut et le fond de la cartouche peuvent comprendre des anneaux souples en plastisol ou des garnitures annulaires dans les disques terminaux en plastisol rigide qui ferment hermétiquemnt les extrémités des plis de la cartouche de filtrage et les extrémités de son tube perforé central. Le liquide que l'on veut filtrer pénètre dans le boîtier au-dessous de la cloison, autour du côté extérieur de la cartouche de filtrage, et le liquide filtré traverse le tube perforé central de la cartouche, autour du côté extérieur de la conduite verticale d'évacuation, monte jusqu'au couvercle hémisphérique pour descendre ensuite par la conduite verticale d'évacuation. Cette construction assure l'élimination automatique de tous les gaz qui pourraient s'accumuler dans le couvercle hémisphérique.

Title: Method and artificial intraocular lens device for the phakic treatment of myopia
Inventor: PRAEGER DONALD
IPC: G09B23/30
Filed: 1987-06-05
Abstract: The placing of an artificial intraocular lens (1) device (IOL) in the anterior chambre of the eye (in front of the iris) for treating myopia. The intraocular lens device (1) includes a meniscus style lens which has a plano anterior surface (3) and a concave posterior surface. The edges (7) of the lens are rounded off and the peripheral portion of the lens (1) is considerably thicker than the central portion of the lens (1). The lens (1) is a minus (negative) refracting lens (1). The lens (1) is suspended in the anterior chamber by three or four carrying angles or haptics (8) having solid footplates (9) at their ends for anchoring the device in the anatomic angle of the eye. The solid footplates (9) are sized to prevent tissue overgrowth and resulting synechia after placement, additionally facilitating subsequent removal of the lens (1) device from the anterior chamber if necessary. A ridged lens glide is also provided to facilitate insertion of the lens device into the anterior chamber during implantation. This lens device is utilized in the phakic state (the state of the natural lens being retained). With the patient's natural crystalline lens being retained, the natural crystalline lens is located in the posterior chamber behind the iris and the artificial intraocular lens of negative power is located in the anterior chamber in front of the iris. The presence of the phakic state allows for accommodation to occur. The intended age range for applicability of the device is approximately from age 20-50.

Abstract: Dans un appareil de mesure de la réflectance de surface (Fig. 2) permettant de diriger de la lumière sur une surface (201, 202, 203), de recevoir la lumière réfléchie par la surface (209, 210) et de mesurer la vitesse de variation du flux lumineux lors du retrait d'un hacheur de lumière (204) situé dans le chemin optique (103), un moyen de détection d'erreur (Figs. 9, 10) détecte et signale une erreur dans le mesurage de la vitesse de variation du flux lumineux. Dans un mode préféré de réalisation, cette vitesse de variation du flux est détectée par la mesure du temps (630) nécessaire à l'intensité lumineuse pour croître d'une première intensité prédéterminée (610) à une seconde intensité prédéterminée (620), et le moyen de détection d'erreur (Fig 9 ou 10) détecte et signale une erreur lorsque l'intensité lumineuse n'atteint pas la seconde intensité prédéterminée (620) dans un délai prédéterminé (630). Lorsqu'une erreur est signalée, l'appareil de mesure de la réflectance de surface est remis à zéro en vue d'une répétition du processus de mesurage. La présente invention est utile dans les réflectomètres portatifs devant être tenus à la main par rapport à la surface à mesurer, l'instabilité dans la tenue de l'appareil par rapport à la surface pouvant provoquer l'erreur.
