Title: Methods for resolving racemic mixtures of 5-substituted 4-hydroxy-2-furanones
Inventor: APPERE GEORGES
IPC: C07D307/60
Filed: 1999-12-29
Abstract: This invention affords a solution tO the technical problem of obtaining one or both enantiomers of 5-substituted 4-hydroxyfuran-2-ones in pure form by resolution with enantiomerically pure bases. Racemic mixtures of 5-substituted 4-hydroxy-2(5H)-furanones, including 5-substitited and 5,5-disubstituted, 4-hydroxy and 3,4-dihydroxy furanones are separated into pure enantiomers by crystallization with an enantiomerically pure base, such as cinchonidine. In specific solvent mixtures, for example, 95 % ethanol, the diastereomerically pure salt of one enantiomer crystallizeS. The enantiomerically pure furanone can then be obtained simply by filtration and treatment of the salt with an acid, for example, trifluoracetic acid, followed by precipitation with water, filtration and drying. Moreover, the other enantiomer may be equally obtained in pure form by evaporation of the mother liquor, followed by the same treament of the salt as described before.

IPC: G01N22/00
Filed: 2001-06-28
Abstract: A microwave resonator apparatus (35) includes a microwave resonant cavity (36) in fluid communication chamber (38) are dimensioned to ensure high attenuation of resonant electromagnetic fields without impeding fluid flow. The resonant properties of the cavity (36) are therefore completely insensitive to variations in the volume of the pressure chamber (38). The resonator has a specialised reentrant geometry. Consequently, two of the cavity's resonant modes depend sensitively upon the formation and volume of any liquid phase present in the cavity. The apparatus and the method are suitable for measuring dielectric properties and phase envelope of fluid mixtures (such as a gas condensate fluid). The apparatus can be used for making several phase envelope measurements without risk of contamination.

Title: Container with illuminated interior visual display
Inventor: HOY RICHARD DALE
IPC: G09F23/00
Filed: 2001-11-15
Abstract: An illuminated message or design (49) is displayed on the surface of an inner container (40) for viewing through an outer container (20). Light emitting diodes (60) are placed under the outer container (20), and near its perimeter, allowing the light to be directly introduced into the peripheral wall cavity (48) formed between the inner container (40) and outer container (20). This allows optimal utilization of the light for lighting the inner container surface generally, and for directing a portion of the light to the inner container's bottom edge for entrapment within the inner container peripheral wall (42). The entrapped light is transmitted through the inner container peripheral wall (42) until the light encounters a nonconformity that redirects the light outwardly through the outer container. Varying inner container (40) shapes interact with the light and create several distinct light mantles.

Title: Software based brake shoe wear determination
Inventor: DEWBERRY JAMES T
IPC: G06F19/00
Filed: 2004-01-09
Abstract: By calculating the energy used by the friction brake equipment, the amount of friction brake shoe/pad wear can be monitored. As the amount of energy supplied reaches a percentage of the friction brake shoe/pad energy design limit, an indication for inspection is provided. If the supplied friction energy continues to increase beyond this point, the brake material must be replaced. The software logic limits are tunable for custom configuring by the transit authority and maintenance personnel. This invention measures the amount of friction effort supplied with respect to time and distance in a software controlled brake system. Furthermore, this invention allows the software to determine when the friction brake material must be replaced based on actual data, which simplifies the maintenance personnel operation procedures, maximizes brake material wear, and avoids costly damage from braking with worn out shoes/pads. The material life remaining for friction brakes is determined currently by a visual inspection followed by a 'best guess' as to whether the material will last until the next scheduled inspection. This invention will annunciate through the software logic program when the friction material requires inspection and replacement. Additionally, the invention provides software logic to indicate the remaining material thickness.
