摘要:
Stable crystals of N-(trans-4-isopropylcyclohexylcarbonyl)-D-phenylalanine may be produced by treating this compound with a solvent at a temperature of at least 10.degree. C. and forming crystals in the solvent at a temperature of at least 10.degree. C. For example, crystals may be formed by crystallization out of solution, or may be formed from solid particles of the compound suspended in a solvent. Crystals formed in this way have different melting point, infra red spectrum and X-ray diffraction patterns from previously known forms of the compound and have enhanced processability, eg. stability to grinding.

摘要:
The present invention relates, generally to a method of determining and assessing cytochrome P450 2D6 isoenzyme (CYP2D6)-related metabolic capacity in an individual mammalian subject via a breath assay, by determining the relative amount of 13CO2 exhaled by a the subject upon intravenous or oral administration of a 13C-labeled CYP2D6 substrate compound. The present invention is useful as an in vivo phenotype assay for evaluating CYP2D6-related activity using the metabolite 13CO2 in expired breath and to determine the optimal dosage and timing of administration of CYP2D6 substrate compound.

In a propeller for use in a ship of the type comprising 4 or more even number blades, at least one of two adjacent blades is inclined forwardly or rearwardly or one inclined forwardly and the other rearwardly so as to make different the rake angles of the two blades. The pitch angle of the rearwardly inclined blade is made larger than that of the forwardly inclined blade. With this construction the mutual interference between adjacent blades is efficiently utilized to prevent decrease in the efficiency even when operating conditions and the diameter of the propeller vary.

A coin dispensing apparatus is provided that has features to easily adjust the distance between the base plate and the rotating disk and to adapt to the thickness of the coins. The coin dispensing apparatus includes a disk (102) which separates coins one by one. A coin base (104) supports the coins which are moved by the disk. A body (100) includes the base and a step section (149) which provides different distances to the base to adapt to the thickness of the coins. A rotating shaft member (160) is selectively attached to the step section and can be adjusted to the body. The rotating shaft member for rotating the disk is selectively attached at the step section in stages. Therefore the distance between the disk and the base is adjusted to adapt the thickness of coin.

摘要:
A device guiding disc to direct discs to a desired location includes a guiding passageway for guiding and aligning the individual discs at an exit position. A pushing device can contact the discs at the exit position and move the disc out of the guiding passageway. A roller member can be positioned adjacent the bottom of the exit position to support and translate the disc as it is pushed by the pushing device. A support device, such as a tapered roller member, can be positioned above the exit position to receive an upper edge of the disc and to operatively position the disc for subsequent contact with the pushing device wherein the disc is positioned at an inclined angle to a longitudinal axis of the guiding passageway.
