IPC: C07D498/18
Filed: 2006-12-12
Abstract: A single-step, one-pot process to obtain zotarolimus and other rapamycin derivatives on large scale that improves currently available syntheses. In one embodiment, dried rapamycin is dissolved in isopropylacetate . After cooling and 2,6-Lutidine addition, triflic anhydride is slowly added at -30° C.  Salts are removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine is added. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as eluant. The product is collected, concentrated, and purified using an acetone/heptane column. The product-containing fractions are concentrated. The product is dissolved in .tau.-BME and precipitated with heptane. The solids are dissolved in acetone, treated with butylated-hydroxy toluene, and the solution concentrated. The process is repeated twice with acetone to remove solvents.  At least one stabilizing agent is added, such as BHT at 0.5% before drying.

IPC: F16D7/00
Filed: 2018-04-03
Abstract: In one aspect, the invention is directed to a decoupler assembly for use between a rotating member such as an alternator shaft and a belt or other endless drive member that is used to drive the rotating member. The decoupler assembly includes a pulley, a hub and an isolator spring that is preferably a coiled, torsion spring. The two ends of the spring are engageable with, at least indirectly, the pulley and the hub for the transfer of torque therebetween. At least one of the ends of the spring engages an engagement structure (on either the pulley or the hub) that includes a helical axial shoulder and a driver wall.  The spring transfers torque in one direction through the driver wall (e.g. when the pulley overruns the hub), but the spring end is not fixedly connected to the driver wall. As a result, when the hub overruns the pulley, there is relative rotation between the spring and whichever of the hub and pulley it is not fixedly connected to. Accordingly, there is relatively rotation between the spring end and the engagement structure (i.e. the helical axial shoulder and the driver wall).  This causes the spring end to separate from the driver wall and to ride up the helical axial shoulder. This causes the spring to compress axially. The coils of the spring have a selected amount of spacing so that the spring can be compressed by a selected amount axially. This sets the amount of relative rotation (and therefore the amount of overrun) that is available between the pulley and the hub in that situation (e.g. in the situation when the hub overruns the pulley).

Abstract: A scratch-off lottery ticket and associated production method are provided wherein a primer material is applied as a dried layer to a front face of a ticket substrate, Game play indicia is printed on the primer layer in a designated game play area, and a scratch-off layer is applied over the game play indicia. The primer layer includes a particulate luminescent material homogeneously dispersed throughout, wherein the particulate luminescent material has a particle size and additive amount relative to the primer layer such that the particulate luminescent material does not add processing or material drying time to application of the primer layer. Fraudulent attempts to remove the scratch-off layer to reveal the underlying play indicia are rendered optically apparent by luminescence of the particulate luminescent material upon subsequent excitation of the play area with an excitation source.
