  • Patent number: 5751606
    Abstract: This apparatus is for testing valves, particularly those adapted for controlling incontinence. Microprocessor computer equipment and programs use specialized test programs and interface equipment to permit the operator to control, display and record a sequence of valve tests using screens, icons and keyboard entries. The tests are either directly computer controlled or computer directed. A manual mode permits the user to enter a specific valve test pressure versus time profile, while an automatic mode permits the user to have the profiles tests repeated automatically by the computer. Both modes provide liquid at controlled pressure to the valve under test and determines the valve's corresponding liquid output rates.

  • Patent number: 5021940
    Abstract: An apparatus and method for automatically controlling a pellet mill. Dry material from a feeder and steam from a valve are supplied to a conditioner, in which the dry material is mixed with the steam to form a hot and moist conditioned mash. The mash is fed into a motorized die or other pellet producing means. During operation, the current load of the die motor and the temperature in the pellet mill are continuously monitored. At period intervals, the system determines whether the current is within a certain tolerance of a predetermined target value. If the current is not within tolerance, the rate of input of raw material is increased or decreased. For each such change in input of raw material, an adjustment is made to the amount of steam input. If the current is within tolerance, the system determines whether temperature of the conditoned mash is near a predetermined target value, and if not, the system adjusts the steam input.
