  • Patent number: 11208023
    Abstract: A Trailer Loading/Unloading System may comprise a tilting flatbed trailer having one or more push bars configured to move along the surface of the trailer bed push palletized cargo off the trailer, move palletized cargo back and forth on the trailer, and prevent rapid descent or undesirable slipping of palletized cargo. Each of the push bars may be secured between a chain on the left side of the trailer bed and a chain on the right side of the trailer bed. These two chains may loop around a rear guide shaft at the rear of the trail and a front guide bar shaft at the front of the trailer. The guide shafts may be secured beneath the surface of the trailer, and may include sprockets around which the chains loop. A motor, e.g., a winch, may be secured to the trailer and may drive, using a sprocket and chain running around a shaft protruding from the motor, one of the guide shafts, e.g., the front shaft, by turning a sprocket mechanically secured to the front guide shaft.

  • Publication number: 20210354614
    Abstract: A Trailer Loading/Unloading System may comprise a tilting flatbed trailer having one or more cross-supports and/or push bars configured to move along the surface of the trailer bed to push palletized cargo off the trailer, move palletized cargo back and forth on the trailer, and prevent rapid descent or undesirable slipping of palletized cargo. Each of the cross-supports may be secured between a chain on the left side of the trailer bed and a chain on the right side of the trailer bed. In one embodiment, the cross-supports may be sufficiently close to place a pallet or other item on top of the cross-supports. In an additional embodiment, a belting loop may cover the cross-supports, thereby allowing for handling of loose material, e.g., gravel, rocks, or soil.

  • Patent number: 8357289
    Abstract: A method and system for removing contaminants from a fluid are provided. The method can generally include providing microstructures in the fluid. At least some of the contaminants in the fluid are attracted to the microstructures and adhered to the microstructures. With the contaminants attached to the microstructures, the microstructures can be separated from the fluid so that the contaminants are thereby removed from the fluid.

  • Publication number: 20110155666
    Abstract: A method and system using hybrid forward osmosis and nanofiltration is disclosed for treating produced water containing contaminant species. The system comprises a forward osmosis cell and a downstream nanofiltration cell. A draw solution fluid cycles between the forward osmosis cell and the nanofiltration cell. The draw solution contains polyvalent osmotic agents producing polyvalent ions in the draw solution. The passage of monovalent ions through the nanofiltration membrane is hindered due to the presence of conjugate polyvalent ions.

  • Patent number: 7901578
    Abstract: A method and system for treating an aqueous stream in the production of hydrocarbon are provided. An osmotic operation is performed between the stream of produced water and a stream of draw fluid to transfer water from the produced water to the draw fluid, thereby diluting the draw fluid to form a stream of diluted draw fluid and concentrating the produced water to form a stream of concentrated produced water. The concentration of the produced water can facilitate the subsequent removal of contaminants therefrom, and, in some cases, the diluted draw fluid can be re-used, e.g., for injection into the well of the hydrocarbon production operation or as a fertilizing fluid.

  • Publication number: 20070209602
    Abstract: Described is an insulated probe device of adjustable anal length for delivering an electroshock stimulus to an animal. The insulated probe device includes an electrode that is positioned in contact with the animal's skin and is disposed within an electrically non-conductive housing. The housing is a two-part housing, where the two parts cooperate such that the ultimate length of the housing is adjustable. The insulted probe devise includes a mounting device that electrically and mechanically secures the insulated probe device to an electronic animal training device. The mounting device is electrically connected to the electrode by way of a conductor, which is disposed within the housing. The conductor is a metal-rubber substance that conducts electricity like a metal and stretches like rubber such that it is capable of various lengths. Consequently, the ultimate length of the insulated probe device is adjustable.

  • Publication number: 20070205893
    Abstract: A system for monitoring and distinguishing occurrences along a perimeter bounded by at least one piezoelectric cable that completely defines the perimeter. The monitoring system utilizes at least one piezoelectric cable that generates electrical signals in response to mechanical stress events. The electrical signals from each piezoelectric cable are analyzed by a processing system to determine event classification and location. The monitoring system alerts users and connects to an existing security system to notify third-parties. The monitoring system includes functionality to communicate with a calibration unit and calibrate itself. The monitoring system also includes functionality to interface with a pet containment system.

  • Publication number: 20070186871
    Abstract: An electrode useful in an animal containment or training device. The electrode is mounted in a housing adapted to be affixed to an animal such that the distal end of the electrode is proximate the skin of the animal. When a control signal is transmitted to the animal via the electrode, the distal end of the electrode extends from the housing and into electrically conductive engagement with the skin of the animal. At other times, the electrode is withdrawn from engagement with the skin of the animal. In one embodiment, the overall length of the electrode is adjustable to select the pressure exerted by the electrode against the skin of the animal.

  • Publication number: 20070125312
    Abstract: A portable animal containment device for confining an animal to a defined area. The portable animal containment device includes a flat and a correction unit. The flat is adapted to be portable and defines the area within which an animal is confined. The flat has an associated presence detector for detecting whether the animal is occupying the flat. When the presence detector indicates that the animal is not occupying the flat, a signal is transmitted to the correction unit by way of wireless communication. The correction unit is carried by the animal and administers a stimulus to the animal when the correction unit receives the signal from the transmitter. Consequently, when the animal moves beyond the boundary defined by the flat, it receives a stimulus, which encourages the animal to remain in the flat.

  • Publication number: 20070120668
    Abstract: A piezoelectric perimeter security system for differentiating between threatening and non-threatening breaches in a property's perimeter and also for article of property containment and pet containment. The system consists of at least one piezoelectric sensor in electrical communication with a conductor wire. When compressed or stressed, voltage is generated within the sensor that is proportional to the amount of force compressing or stressing the cable. A processing device receives this voltage and converts it to a local activity signal. This signal is then compared with other signals stored in the system's memory in order to identify the type of entity causing the voltage across the cable. If the entity is deemed a security threat then an appropriate countermeasure such as a siren or other alert is actuated. The conductor wire also carries a signal received by a signal receiver that is placed on either a pet or an article of property.
