Abstract: An automatic, thermal print on demand labeler is provided. The thermal print head is placed above the axis of rotation of the rotary head, with a cylindrical platen mounted horizontally opposite the print head. A stripper pin is mounted below the platen; the pin is positioned very close to the print region of the print head. This positioning of components results in a label being printed and dispensed onto a bellow in one index of the multi-bellow rotary head. Independent direct gear drive trains are provided for the rotary head and label tape drive.

Abstract: A quadrupole mass spectrometer alternates between increasing mass and decreasing mass scans for the purpose of decreasing inter-scan delays. By alternating increasing and decreasing mass scans, the next scan starts where the last scan ended reducing the settling time required. Backsteps may be eliminated by scanning the RF and DC non-linearly.

Abstract: An improved method for administering parthenolide and/or feverfew extract as a dietary supplement is provided, wherein an oral dosage composition comprising a dietary supplemental amount of parthenolide in a predetermined dosage amount of at least about 0.05 mg of parthenolide is orally administered to a patient. At least a portion of the administered oral dosage composition is retained by the patient in the oral cavity for a time sufficient to allow absorption of parthenolide by oral mucosal tissues. Compositions particularly suitable for oral mucosal administration of a parthenolide dietary supplement are also provided.
