The antimicrobial compounds are of the formula I: wherein R, R1, R2, X and Y are as defined herein.

Abstract: Provided is a process for making a tertiary aminoalcohol compound. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The process uses fewer steps than conventional processes.

Abstract: Nitroaldol (“Henry”) reactions between nitroalkanes and aldehydes in the presence of a catalyst and a two-phase reaction medium produce nitroalcohols at increased reaction rates compared to single-phase organic solvent systems, and do not require use of surfactants as is typical of single-phase aqueous solvent systems and solventless systems. The reaction medium comprises an organic solvent phase and an aqueous solvent phase. The aqueous solvent may be 100% water.

Abstract: Provided is a process for making an aminoalcohol compound. The process comprises using an excess amount of aliphatic aldehyde in a condensation step between the aldehyde and a nitroalkane, and using an aldehyde scavenger in a reductive hydrogenation step. The process yields aminoalcohol compounds exhibiting reduced color and odor.

Abstract: A recovery utility apparatus for expediting recovery time during failure of one or more database data sets is provided. A backup copy restore utility is configured to read and restore a backup copy of the database data set. A change accumulation manager is configured to read detail records in an incomplete change accumulation data set. A log manager is configured to read a log to derive updates subsequent to a merge end point, wherein the updates are reflective of spill records. An image copy restore utility is configured to apply the detail records to the backup copy to thereby create a restored database data set. A database update manager is configured to apply the updates to the restored database data set.

Abstract: In a rotary press, temperature of a printing plate is sensed by an infrared temperature sensor mounted in close proximity to a cylinder carrying the printing plate. Sensor output is used to control a closed loop of a water circulating system which includes one or more water-carrying rollers in an ink train. A water cooler and a water heater are provided in the closed loop and are controlled in response to the sensor output to maintain the printing plate at a temperature which allows proper inking thereof.

Abstract: An inflatable dock seal for mounting about a loading dock opening to provide a cushioned seal against a vehicle has an upper inflatable curtain and a pair of inflatable side members; the side members inflate laterally of the opening directly towards each other along a phantom axis of inflation which is perpendicular to a phantom axis of entry of the opening; the side members are in particular L-shaped and inflate laterally of the L-shape; the inflatable foot of the L-shape forming a bottom seal extending from the wall to the leg of the L-shape spaced from the wall; the spacing of the leg of the L-shape from the wall provides a window for entry of natural light to the opening.

Abstract: An exercising bicycle handlebar arrangement for retrofit installation on a bicycle frame includes a handlebar assembly having a pair of handgrips, a pivot assembly for pivotally connecting the handlebar assembly to a handlebar mounting stem of a bicycle frame, and shock absorber type struts for controlling the force required to displace the handlebar assembly in a forward-and-back oscillation about the pivot assembly, the struts being pivotally connected to the handlebar assembly and an upper end portion and to a front wheel axle in a free rolling manner at a lower end portion. In an installed condition on a bicycle, the handlebar assembly can be turned freely about a generally vertical axis and can be swung forward and back against a preset resistance about a generally horizontal axis during riding of the bicycle without affecting free rotation of the front wheel of the bicycle.

Abstract: A resiliently compliant, variable stiffness wire mesh structure, primarily for space applications, characterized by its lightweight construction, its compact stowage and deployment capability, and its ability to maintain its nominal shape under widely varying thermal conditions. The structure has a frame supporting a wire mesh including spring-like longitudinally compliant wires which are terminally secured to the frame to constitute primary structural elements of the mesh and are prestressed in a manner such that the compliant spring wires in different sections of the mesh have differing spring rates or stiffness. This non-uniform stiffness of the mesh is designed to maintain the mesh taut under widely varying thermal conditions and thereby avoid the formation of slack in the mesh wires which would allow out-of-plane displacement of the mesh. The described mesh structure is a wire mesh antenna reflector for space applications.

Abstract: A portable court boundary for a sport such as badminton or volleyball is formed of flexible cord or twine. The boundary is designed to be wound upon a specially constructed spool so that it can be easily unrolled and laid in place on the surface where it is desired to play the game. The spool has a hollow interior within which are stored hooks for anchoring the boundary to the playing surface. To assist in properly disposing the boundary, each of the boundary corners is color coded with a different color.
