  • Thickened and gelled systems based on starch and glucomannan
    Patent number: 5308636
    Abstract: The viscosity of gellable starch-based systems is enhanced synergistically by admixing with the starch a glucomannan such as konjac. The improved viscosity is maintained at elevated temperature. Other food ingredients may be added to the mixture prior to gelation. Sols formed from the mixture exhibit improved cling to smooth surfaces such as poultry, fish and vegetables, and the resulting gels have high strength and stability even at elevated temperature. The gels become thermally stable by addition of an alkali either before or after gelling, or by freezing the gels with or without addition of an alkali. The compositions are useful in a wide variety of food and industrial applications.

  • Self diagnostic wheel balancer
    Patent number: 5307279
    Abstract: The invention provides a wheel balancer that is able to determine if its measurements are accurate. The invention takes a set of measurements and determines if the measurements are sufficiently consistent. If they are sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention rejects at least one data point and collects more measurements until either the invention yields sufficiently close data points or the machine is stopped. A display is provided for diagnostic messages.
