  • Patent number: 7491321
    Abstract: Contaminants are removed from fluid in a system where the fluid is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allow oxygen-containing gas from a compressed gas source to flow into the tank through a shuttle valve, which is opened by the gas pressure. Simultaneously, a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The solenoid valve also operates to close the gas supply line and connect the shuttle valve through a vent to atmosphere. Pressure within the tank closes the shuttle valve, which in turn closes the drain valve and disconnects the shuttle valve from the tank. A one-way-flow valve prevents fluid or gas from flowing from the tank backwards through the shuttle valve to the solenoid valve and out the vent.

  • Patent number: 7156995
    Abstract: Mineral contaminants are removed from water in a system in which water is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allows air from a compressor to flow into the top of the tank through a shuttle valve which is opened by the air pressure. Simultaneously a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The shuttle valve, closed by the solenoid valve, closes the air supply line and connecting the shuttle valve to atmosphere, and pressure within the aeration tank can close the shuttle valve, which causes closing of the drain valve. The part of the valve which opens the drain is made responsive to excess pressure within the air tank to open the drain and so acts as a pressure relief valve.

  • Patent number: 6935273
    Abstract: An improved bedding for livestock of this invention provides a bed strip for livestock having at least two elastomeric belts bonded together, one on top of the other, to form at least one bed with at least two chambers, front and rear, expandable under fluid pressure, that, once properly filled with a working volume of fluid, will each attain a convex pillow-like shape. The fluid volume in the chambers is such that when an animal steps on the rear chamber of the bed the top belt makes contact with the bottom belt to provide a stable base for the animal's foot, yet, when the animal drops to its knees on the front chamber of the bed, during the process of lying down or rising to standing, the knees are supported by a fluid cushion between the top and bottom belts.

  • Patent number: 6862866
    Abstract: Resealable zipper plastic bags have upwardly protruding support members on each side of the bag mouth which are engaged within downwardly opening channels of two opposed indexer assemblies. With the bag mouth under tension, a slider assembly engages the bag slider, moves it to a fully closed position, then advances the slider to a fully open position. The indexer assemblies are moved toward each other to relieve tension on the bag mouth and cause the mouth to splay open. An insert plate is inserted and rotated to spread the bag mouth for introduction of product through a product chute. Once full, the chute and spreader assembly are withdrawn, tension is applied to the bag mouth, and the slider assembly moves the zipper slider to a fully closed position. The bag support members are then released from the indexer assemblies and the product filled bag is discharged from the apparatus.

  • Patent number: 6815666
    Abstract: A negative ion source placed inside a negatively-charged high voltage electrode emits a beam which is accelerated to moderate energy, approximately 35,000 electron volts, and filtered by a momentum analyzer i.e. an analyzing bending magnet, to remove unwanted ions. Reference ions such as carbon-12 are deflected and measured in an off-axis Faraday cup. Ions of interest, such as carbon ions of mass 14, are accelerated through 300 kV to ground potential and passed through a gas stripper where the ions undergo charge exchange and molecular destruction. The desired isotope, carbon-14 along with fragments of the interfering molecular ions, emerge from the stripper into a momentum analyzer which removes undesirable isotope ions. The ions are further filtered by passing through an electrostatic spherical analyzer to remove ions which have undergone charge exchange. The ions remaining after the spherical analyzer are transmitted to a detector and counted.

  • Patent number: 6701830
    Abstract: Above-ground tanks form brining cells into which cheese blocks are conveyed by common inlet and outlet flumes. Each cell has a removable conveyor assembly having a looped link belt driven around a frame by a motor. Perpendicular, tubular, or hinged segmented flights project from the belt to engage infed cheese blocks, and submerge a series of rows of blocks. An infeed flume delivers a stream of cheese blocks to a cell. Once a level below a flight is filled, the conveyor is actuated to submerge that level, and the next level is then filled until the tank is filled. After brining, the conveyor is incremented to discharge the cheeses flight by flight into an outlet flume. The flume may have a lower segment narrower than an upper segment, such that by draining the tank smaller cheese blocks may be better controlled.

  • Patent number: 6698525
    Abstract: A low till agricultural implement has a frame with a hitch for attachment to a tractor. A straight coulter composed of an array of parallel circular blades is mounted to the front of the frame, and is followed by a spiral reel assembly and a spike tooth harrow assembly. The circular blades are mounted perpendicular to rotating shafts, and slice through field residue and soil with minimal side movement of material. The blades of the following reel then make cuts nearly perpendicular to those made by the circular blades. A trailing level bar follows the spiral reel. The implement aids in drying the soil surface layer, and, by cutting up residue and even spreading, the implement helps to warm up the soil.
