  • Patent number: 9415941
    Abstract: A vibration generating assembly is described, and which includes an exterior housing having an internal cavity, and opposite first and second ends; a reciprocally moveable carriage which is biasingly supported within the internal cavity of the housing; and an electrical transducer have a magnet which is supported by and reciprocally moveable relative to the biasingly supported carriages, and the electrical transducer has a fixed cylindrically shaped electrical coil which is mounted on the exterior housing.
    Type: Grant
    Filed: June 30, 2015
    Date of Patent: August 16, 2016
    Assignee: Key Technology, Inc
    Inventors: Christopher Woiler, Dean Dunham
  • Patent number: 9408283
    Abstract: An electrical grounding arm is described and which has a predetermined geometry that dissipates stress imparted to the electrical grounding arm by the repeated movement of the electrical grounding arm, so as to inhibit stress related damage from being imparted to the electrical grounding arm, and which further, inhibits a source of fluid from pooling or collecting on the exterior facing surface thereof in order to prevent an unsanitary condition from developing.
    Type: Grant

  • Patent number: 9181037
    Abstract: A conveyor assembly is described and which includes a reciprocally moveable conveyor bed, having a product conveying surface, and a reactive mass electrical transducer, which is oriented in spaced relation relative to the conveyor bed and which, when energized, imparts reciprocal motion to the conveyor bed to move the product along the product conveying surface of the conveyor bed.

  • Patent number: 9132966
    Abstract: A vibratory conveyor is described and which includes a base frame; a reciprocally moveable conveyor bed which is resiliently supported on the base frame by a first multiplicity of elongated springs, and a conveyor bed driving assembly which includes a reciprocally moveable driver which is biasingly supported on the base frame and which further when energized, magnetically cooperates with the base frame so as to impart movement of the reciprocally moveable driver along a given path of travel, and which simultaneously generates a force which causes the reciprocally moveable conveyor bed to reciprocate in a predetermined manner so as to move product along the reciprocally moveable conveyor bed.

  • Patent number: 8733540
    Abstract: An excited frame vibratory conveyor is described and which includes a base frame; a motor mount made integral and with the base frame; a pair of vibratory motors mounted on the motor mount; and an electrical circuit for energizing the pair of vibratory motors in a fashion which reduces movement of the base frame in a vertical direction.
