  • Patent number: 11884555
    Abstract: A fluid vapor distillation apparatus. The apparatus includes a source fluid input, and an evaporator condenser apparatus. The evaporator condenser apparatus includes a substantially cylindrical housing and a plurality of tubes in the housing. The source fluid input is fluidly connected to the evaporator condenser and the evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid. Also included in the fluid vapor distillation apparatus is a heat exchanger fluidly connected to the source fluid input and a product fluid output. The heat exchanger includes an outer tube and at least one inner tube. Also included in the fluid vapor distillation apparatus is a regenerative blower fluidly connected to the evaporator condenser. The regenerative blower compresses steam, and the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid. The fluid vapor distillation apparatus also includes a control system.

  • Patent number: 4757984
    Abstract: A method and apparatus are disclosed for providing a collator having a variable raceway jam fault detection arrangement. A plurality of hoppers are arranged in an array, each adapted to feed signatures onto a raceway having a moving chain. The chain has spaced apart chain pins, the distance therebetween defining signature feed locations. A plurality of jam detector switches are located along the raceway and are adapted to detect a signature jam, e.g., a signature overlying a chain pin. A controller monitors each of the jam switches. The operator enters into the controller a desired rejection pattern for each of the jam switches separately.

  • Patent number: 4753430
    Abstract: A method and apparatus are disclosed for controlling a collator. A microcomputer learns hopper insertion points, jam switch insertion points, and hopper miss and double feed service angles relative to a reject gate. Based on the learn collator configuration, the controller controls collator operation. When a hopper phase adjustment is made by an operator, the controller automatically re-learns the hopper service angles during a ripple start of the collator and adjusts its reject data in response thereto. A miss verify sensor arrangement permits the controller to monitor for phase adjustments after a ripple start and to warn the operator upon such occurence.
