  • Patent number: 4799596
    Abstract: Method and apparatus for controlling a color sorting machine which sorts particulate products based on a color difference between the product and a background. A photoelectric cell receives light reflected from the product and provides an output signal to a microprocessor. The microprocessor uses photoelectric cell output signals of known good products to establish a range of predetermined acceptance values. If the detected signal falls outside the predetermined range, it is determined that the product is defective and an eject signal is provided to an ejector which ejects the bad product from the machine. Outside of the microprocessor, a comparator first compares the photoelectric output signals with the predetermined range of values established by the microprocessor. If the comparator detects a defective product, it provides an eject signal to the microprocessor which then commands the ejector to eject the defective product.

  • Patent number: 4498362
    Abstract: An apparatus for cutting rod or strand-like products comprised of a rotary holder positioned adjacent the outlet end of a tube from which a water jet is discharged and in which the rod or strand-like products are entrained. The rotary holder includes a plurality of individually actuatable cutting blades movable between cutting and non-cutting positions. An optical scanner determines the presence of dark or discolored areas on the products and generates a signal timed to actuate a sufficient number of cutting blades which will cut through the product as it emerges from the tube and separate the discolored area from the acceptable areas. The cutting blades can be held inoperative by electromagnets and returned by a cam. Alternatively, the blades can include a deflection member and jet nozzles can be employed to pivot the blades in and out of the cutting position.

  • Patent number: 4390782
    Abstract: A method and apparatus for measuring the liquid level in each of a plurality of containers in which each bottle passes in succession on a conveyor belt past a measuring station and between a radiation source and detector at the station. Each bottle is detected as it reaches the station to trigger actuation of the radiation source for a given number of time periods. Each period is of fixed duration and the time between periods is varied in accordance with the speed of belt and container so that each container receives the same radiation regardless of its speed.
