  • Patent number: 6305524
    Abstract: In a feeder supplying assembly components to another machine, an electronic control device monitors a horizontal buffer zone. Pulses of compressed gas are intermittently employed to lift components upon detecting the absence of a component in a portion of such buffer zone. The grooved chute member has a shape resembling the symbol for a square root after replacing the angles with curves. The stream of flowing components can be quite fast because components are directed to fall into the downsloping gathering portion of the grooved chute at an upper, middle, and lower portions. More rapid multi-stage alignment of components is expedited by a zone underneath a deflector and a transition zone, with an alignment passageway between such zones.

  • Patent number: 6230875
    Abstract: A vibratory conveyor capable of fluidizing particulate material is capable of separate control of direction, velocity and fluidization of material. The material is placed on a conveyor and vibrated by separate vertical and horizontal components of vibration. The frequency of both components is synchronized over an operating range. Various independent changes in amplitudes can affect the degree of fluidization and flow direction for any particular frequency. For any combination of amplitudes, changes in frequency affect fluidization and velocity. The present invention is adaptable for a range of applications that include drying wood wafers, hog fuel or other organic particulate, warming wood chips, scrubbing flue gas, filtering acting as a reactor and as a gas processor.

  • Patent number: 4593603
    Abstract: An asymmetrical vibrator is provided, which is actuated by compressed air. The vibrator operates in a case, which has two bores disposed parallel on opposite sides of the casing. One of the bores is smaller than the second bore and the piston operating in the small bore is called the slow piston, since it is actuated with air to a relatively slow motion and the piston operating in the second larger bore is called the fast piston, since it is moves at a larger speed when driven directly by the compressed air. The asymmetric vibration motion can be employed to transport materials upwardly in factories and assembly stations. The air operated asymmetric vibrators need low maintenance and do not entail the spark dangers caused by the presence of electrical wiring for electrical drive motors.
