Title: Atorvastatin calcium in a pharmaceutical form, composition thereof, and pharmaceutical formulation comprising atorvastatin calcium
Inventor: KERC JANEZ
IPC: A61K31/40
Filed: 2002-03-13
Abstract: Atorvastatin calcium, the substance known by the chemical name (R-(R*,R*))-2-(4-fluorophenyl)-.beta.,.delta.-dihydroxy-5-(1-methylethyl)-3-phenyl-((phenylamino)carbonyl)-1H-pyrrole-1-heptanoic acid hemi calcium salt is known as HMG-CoA reductase inhibitor and is used as an antihypercholesterolemic agent. Atorvastatin in the pharmaceutical compositions available in the market, is usually prepared as its calcium salt since it enables atorvastatin to be conveniently formulated in the pharmaceutical formulations, for example, in tablets, capsules, powders and the like for oral administration.  Atorvastatin calcium can exist in an amorphous form or in one of the at least four known crystalline forms (Form I, Form II, Form III and Form IV).  Atorvastatin calcium is the substance which is sparingly soluble in water, with pKa 4,5, and it has been found that the crystalline forms are less soluble than the amorphous form, which may cause problems in bioavailability of atorvastatin in the body. The present invention solves the problem of providing therapeutic equivalence of atorvastatin pharmaceutical formulation regardless the form (crystalline, amorphous, mixture of both) of atorvastatin calcium used for its preparation.

Abstract: The U-shaped concrete units and joining corner units for wall construction provide an unmached horizontal and vertical interconnection of grout in a lattice formation between the horizontal reinforcing steel bars, or with the called grid units. For running bond pattern vertical connections using short steel bars with hooks, and for stack bond patten construction allows to use longer vertical bars because of the manuvering possibility with the bottom recessed U-shaped units between the vertical bars.      This method of reinforcing allows to design a wide range of wall strength to resist cracks to appear by light tremor.      The concrete units with grout may also be used for non-reinforced building construction where the lattice formation will provide a unique lateral strength.      The construction whith these concrete units provide an opportunity to reduce the cuts of concrete blocks at construction sites, the cost of those operations, side effects of dust inhalation and accidents.

Filed: 2002-05-14
Abstract: Device and method for diffusing a protective flux. In order to protect one area of a service station, a more or less parallel air flow is created in the direction of the area. Above a threshold F, the air flow has a gradually increasing speed V 22 and, below the threshold, the air flow speed V 21 is more or less uniform along the length of a flow section in a plane P which is transverse to the direction of flow D. One possible configuration for an air flow diffusion device, which allows a confinement barrier to be created, consists of a diffusing wall comprising a main wall and a lateral wall. The main planar wall is adapted to diffuse a main laminar flow in the sterile area to be protected. The lateral wall is adapted to diffuse a lateral flow divergent from the main flow. A skirt is disposed to create an obstacle to the lateral flow and to accelerate the flow by of deflection.

Title: Generalized index set splitting in software loops
Inventor: TAL ARIE
IPC: G06F9/44
Filed: 2003-12-19
Abstract: There is disclosed a method and system for determining the bounds of generated software loops, where the relationships between split points and loop bounds are not known, or only partly known, at compile time. A "sub-range tree" is built with a root node representing the original software loop. Each sub-node represents a sub-range of the original software loop split by one or more split points. Each edge between nodes of the sub-range tree is marked with either a "then" (T) or "else" (E) marker, according to a predetermined scheme. Once the sub-range tree is built, a "path-from-root" is analyzed for each leaf node of the sub-range tree, and "dead" inductive control flow branches are identified and folded. The growth of software loop code based on the sub-range tree may be restricted by a predetermined code growth limit.

Le couloir de visualisation présente une distance suffisante qui permet de focaliser l'oeil à l'infini et de l'adapter à des cibles situées à distances réelles, telles que des distances rapprochées, notamment une distance de lecture. L'appareil de mesure objective de la réfraction peut être placé dans le couloir de visualisation afin de mesurer l'oeil pendant que celui-ci est focalisé sur la cible visuelle en champ libre. Dans une autre forme de réalisation, l'appareil de mesure objective de la réfraction peut mesurer des caractéristiques de réfraction d'un oeil en continu, de façon sensiblement continue, ou par incrémentation, pendant l'adaptation dynamique ou des variations des conditions d'éclairage tout en fournissant des cibles visuelles à distances réelles avec le champ libre traversant l'appareil. Dans une autre forme de réalisation, le dispositif mesure objectivement des caractéristiques de réfraction des deux yeux travaillant ensemble pendant la visualisation de la cible visuelle en champ libre.

Patent CA-2464922-A1 (CA)
Inventor: BETTENCOURT HAROLD RAY III
IPC: F01P7/02
Filed: 2004-04-20
Abstract: A control for changing direction of air flow through a cooling core in response to an external signal and a purge signal includes a logic circuit and a relay assembly. The logic circuit generates a fan control signal based on the external signal, which causes the fan to turn on and operate in a cooling mode and generate an air flow through the cooling core in a first direction, or operate in a neutral mode with reduced or no air flow through the cooling core. The logic circuit also includes at least one timer that internally generates the purge signal, which is then transmitted by the logic circuit to the relay assembly. The purge signal overrides the fan control signal and causes the fan to operate in a purge mode, which causes air flow through the cooling core in a second direction opposite to the first direction.

Abstract: Arsenic trioxide, an inorganic compound, is commercially available anti-cancer agent but it carries significant toxicity. Organic arsenicals, on the other hand, are much less toxic, to the extent that the methylation of inorganic arsenic in vivo into organic arsenicals has been considered a detoxification reaction. New organic arsenic derivatives have been synthesized, including S-dimethylarsino-glutatione, S-dimethylarisno-thiosuccinic acid and S-dimethylarsino-thiobenzoic acid, and established its potent in vitro cytotoxic activity against numerous human tumor cell lines, both of solid and hematological origin, as well as against malignant blood cells from patients with leukemia. Results form a basis for the development of S-dimethylarsino-glutathione, S-dimethylarsino-thiosuccinic acid, S-dimethylarsino-thiobenzonic acid, and other organic arsenicals as an anti-cancer therapy, combining high efficacy with very low, if any, toxicity.
