  • Publication number: 20140249190
    Abstract: The present invention relates to processes for the preparation of tablets which dissolve rapidly in the mouth and provide an excellent mouthfeel. The tablets of the invention comprise a compound which melts at about 37° C. or lower, have a low hardness, high stability and generally comprise few insoluble disintegrants which may cause a gritty or chalky sensation in the mouth. Convenient and economically feasible processes by which the tablets of the invention may be produced are also provided.

  • Patent number: 4309112
    Abstract: A method and apparatus for the detection of the magnitude of selected chemical substances in a biological fluid by fixed rate analysis. Photometric analysis is performed sequentially upon a standard solution and then upon an unknown sample to determine the rate reaction in each. The method and apparatus minimize or eliminate error in equipment drift and calibration. The rate reaction is manually initiated in a standard solution carrying a known amount of a chemical substance. The standard is then placed into a photodetector circuit to produce a voltage representing optical density which increases at a constant but unknown rate during the reaction. The time required for the voltage to change from a base-line level to a selected and pre-set value is then measured and stored as a calibration reference time.

  • Patent number: 4215700
    Abstract: A blood collection device used in taking a small sample from a patient for test purposes is provided with a capillary tube and vented tube holder disposed in the upper end of a blood collection container. Integral radial extensions allow the container to be centrifuged in a centrifuge normally used for containers of larger diameter. An integral flexible strap connects a stopper to one of the radial extensions so that the stopper remains with the container.
