Abstract: The present invention relates to naphthopyrans, particularly 3,3-[substituted]-naphtho[2,1-b]pyrans and 2,2-[substituted]-naphtho[1,2-b]pyrans and particularly to novel substitution on the 3-position and 2-position, respectively, of these naphthopyrans. It has been found that there are classes and types of substitution on the 3-position and 2-position (especially combinations of 3,3-substitution and 2,2-substitution) which are novel. Some of these substitutions provide particularly desirable properties.

Abstract: A method of playing a wagering game comprises: placing a wager to participate in a game comprising a first and second gaming segment, wherein outcomes of the first gaming segment are based on random symbol selection; playing the first game segment, wherein if a predetermined qualifying outcome is achieved, awarding the player a first payout; playing a second game segment if the player obtains a predetermined qualifying outcome in the first game segment; the second segment randomly determines a factor as a determined factor; and awarding the player a second payout that is equal to the determined factor multiplying at least one of: a) the wager placed to participate in said game; b) the first payout amount; and d) the wager placed to participate in said game and the first payout amount. Apparatus used for playing the wagering game may include a panel display with randomly displayed factors for use in the second gaming segment.

Abstract: A video slot reel game is provided with a supply of symbols for the play of video gaming formats. The supply of symbols appears as an image of a continuous strip or continuous element of images in a virtual continuous loop or extended strip. For example, a continuous loop may contain 1000 symbols, the loop progresses through a first column in a video slot image (exposing the desired number of frames within the strip of the loop, for example, 1, 2, 3, 4 or 5 frames exposed for active play), the forward part of the strip of the loop is then returned to another column to expose the desired number of frames, and then the forward part of the loop is again returned to the video screen in still another column to expose another desired number of play active frames. This manner of providing the frames in a continuous (or at least extended) strip or loop provides both additional imagery and an opportunity for varying the probabilities of the game easily.

Abstract: A class of customizable injection devices or delivery instruments whose basic form is a stiff tube with holes of user-selectable size at several user-selectable places is described. The use of this device includes a method of selection and construction of a particular device from such a class of devices for a particular treatment procedure using computer-assisted means. Thus, the user may make selections among available or creatable choices (such as selection of hole size, selection of hole location, number of holes, etc.), and a method can be practiced for making such user-selection serve the goals of delivery of materials such as drugs, cells, or of devices sufficiently small and numerous to be delivered in fluid suspension.

Abstract: This invention provides a method and a device for treating hemodynamically significant aneurysms especially in the intracranial and extracranial circulation regions using either X-ray fluoroscopy or real-time magnetic resonance (MR) imaging guidance. An MR-visible parachute-shaped occlusion device, e.g., containing multiple elongated filamentary loops made of a memory metal, elastomeric hydrogel or other expansile material, is deployed into the aneurysm by radial expansion of the expansile material outwardly into contact with the interior aneurysm surface. The device is firmly positioned against the interior aneurysm surface using a coating which adheres to that interior aneurysm surface. The device may be filled with a hardenable polymer for permanent and complete aneurysm occlusion.

Abstract: A method of playing a wagering game, such as a casino table game or video game, including a playing card wagering game method involves each player placing a multiple part bet, such as a two, a three or a four-part bet. At least one game symbol is designated as wild. A certain position in the order of play is reached (such as with cards being dealt by the dealer, two face down to the dealer and three face down to each player), and the player is given an opportunity to withdraw at least one part of the multiple part bet from risk, although at least one part of the multiple part bet must remain at risk during the play of the game. Players evaluate their position in the game and the dealer or the program for the game gives each player the choice of withdrawing or leaving a first part of the bet. The game is then completed. For example in a card game, the player's cards are shown, and all remaining bets, which were not withdrawn, are resolved according to a pay table.

Abstract: A method of scoring a video wagering game is disclosed. The method includes placing a wager to participate in a video wagering game, and playing a first segment of the game. The first segment is played until a set of predetermined conditions has been met. A payout value is assigned to a winning outcome of the first segment. When the predetermined conditions have been met, the player plays a second segment of the game. The outcome of the second segment determines a factor that is at least equal to one. The payout value assigned to the first segment is multiplied by the factor to determine the game payout.

Abstract: Chemiluminescent detection of molecules of synthetic or natural origin such as proteins and nucleic acids (DNA and RNA), as well as other biologic molecules, is increasingly replacing radioactive detection as the method of choice where sensitivity is critical. In such assays, luminescence is customarily achieved by the oxidation of a luminol or isoluminol substrate in the presence of an oxidizing agent such as hydrogen peroxide or hydrogen peroxide source, such as perborate, and a peroxidase catalyst such as horseradish peroxidase. To obtain useful levels of luminescence (e.g., detectable levels) by customary techniques, a luminescent enhancer is also present during oxidation. It has been found in the practice of the present invention that azine enhancers have contained an impurity which reduces the properties of the chemiluminescent assay working solutions.

Abstract: The removal of certain reaction impurities in the manufacture of polysulfone polymers has been found to reduce the undesirable coloration in the final resin. Control of synthesizing reactions, manufacturing processes, and/or purification of specific ingredients assists in the removal of specific, undesirable impurities. The yellowness index, as determined by ASTM D1925 or ASTM E313, in the commercial grades of polysulfone resins has consistently been well above 1.0 for commercial polysulfone resins. The present invention provides polysulfone polymers after processing (e.g., injection molding) where the yellowness index is below 1.00, below 0.75, below 0.50, and even below 0.25.

The process may etch the first and third metal layers simultaneously or sequentially.

Abstract: The salt of a sulfonated succinic acid is cyclized, then converted to novel sulfonated hydroxamic acids by reaction with hydroxylamine (which is added or formed in situ), and the novel hydroxamic acid is then cyclized to the sulfo-N-hydroxysuccinimide salt. This synthetic procedure is simple, direct, and more rapid than present procedures for synthesis of the succinimide. Novel sulfo-hydroxamic acid intermediates are formed during this procedure.

Abstract: Novel C3-substituted cyclodeca-1,5-diynes can be prepared through novel synthetic procedures using starting (E)-C3-substituted-4-(aryl- or heteroarylmethylidene)cyclodeca-1,5-diynes reagents. Both the C3-substituted cyclodeca-1,5-diyn-3-enes and the starting reagents have improved thermal stability compared to unsubstituted counterparts.

Abstract: Multifocal ophthalmic lenses may be manufactured by either injection molding and casting methodologies. The use of two opposed tools (mold faces) with relatively centered faces, but with significantly differing diameters can be used to provide multifocal ophthalmic lenses. The process is surprisingly capable of providing multifocal lenses with good control of the thickness of the lenses, with relatively thin center thicknesses (e.g., less than 4.7 mm, or less than 3.5 mm) and relatively thin edge thicknesses (e.g., 0.5 to 2.5 or to 2.0 mm). The tool faces (the molds for the front and rear surfaces) may be readily replaced within the mold to enable manufacture of a wide range of lens prescriptions with minimum down time.
