  • Gelatin pharmaceutical formulations
    Patent number: 5532002
    Abstract: Hard gelatin capsules contain: (a) a fat-soluble nutrient, such as a fat-soluble vitamin (A, D, E or K) or an unsaturated fatty acid glyceride; (b) a nonionic surfactant, such as a polyoxyethylated (optionally hydrogenated) castor oil, and/or a polyethylene glycol; (c) a gelatin softening agent such as glycerol, propylene glycol or, preferably, glyceryl mono-oleate; and optionally (d) water. The problems of embrittlement conventionally encountered with hard gelatin capsules containing fat-soluble nutrients are reduced or avoided.

  • Digital to analogue converter adapted to select input sources based on a preselected algorithm once per cycle of a sampling signal
    Patent number: 5138317
    Abstract: An n-bit DAC of the kind having at least 2.sup.n -1 sources, typically current sources, especially for use in oversampling ADC's enables a resolution accuracy in excess of 18 bits by selecting the sources in a dynamic manner. A source selection circuit typically an at least 2.sup.n -1 to 2.sup.n -1 multiplexer, connected between the digital input lines and the DAC switches selects the sources based on a predetermined cyclic algorithm which converts DAC errors into noise and shifts the noise energy into unwanted parts of the spectrum.

  • Pharmaceutical delivery systems
    Patent number: 4944949
    Abstract: Non-steroidal anti-inflammatory drugs (NSAIDs) including diclofenac, flufenamic acid, flurbiprofen, ibuprofen, indomethacin, ketoprofen, naproxen, phenylbutazone, piroxicam and sulindac are administered in micelles to alleviate their adverse effects on the gastrointestinal tract. The drugs are formulated with surfactants such as polyethoxylated nonionics to give micelle-forming compositions.
