  • Patent number: 7083730
    Abstract: Sodium chloride and purified water are recovered by treating salt water that contains sodium chloride with an integrated reverse osmosis and electrodialysis system, which includes an efficiency-enhancing feature that is one or more of the following: the use of univalent anion and univalent cation selective membranes in the electrodialysis unit; the addition of a nanofiltration unit to process the diluate from the electrodialysis unit; or operation of the electrodialysis unit at an elevated pressure. Magnesium and bromine can optionally be produced when the salt water contains these materials.

  • Publication number: 20060115587
    Abstract: A method and apparatus for applying a liner to a pipe is disclosed. The apparatus includes a base assembly having a plurality of guide rails and a shuttle plate attached thereto. The apparatus also includes a motor module attached to an end of the base assembly. An extension arm is connected to a top surface of the shuttle plate. The extension arm has a spray head assembly attached at an opposite end thereof. The extension arm and spray head assembly will move relative to the base assembly of the apparatus. A fast cure coating will be applied via the spray head assembly to the interior surface of a pipe being rehabilitated. The spray head assembly will have an air blow off mechanism therein thus allowing for the tip of the spray head assembly to stay relatively clog free during the fast cure coating operation of the apparatus.

  • Publication number: 20060111016
    Abstract: Described herein is a system and method for displaying a raised impression of a design through a cover, such as an overgarment or other material. For example, a star or other desired design may be covered by a garment in order to display a raised impression of the design without exposing the entire design. Such raised impressions can serve many purposes including a method for women to attract males, advertising, to protest, serve as a reminder, notice to others, or other similar uses where raised impressions provide a means to convey a message. Such raised impressions provide a means to convey messages without explicitly broadcasting the message.

  • Publication number: 20060072550
    Abstract: A method and apparatus for providing useful packet data to a CALEA/Legal Intercept collection function. At an access point to a network such as the Internet, sources and destinations of data connections are examined to determine whether any of the bearer messages should also be routed to a CALEA/Legal Intercept monitoring system. If this condition is recognized, the bearer messages and corresponding signaling control messages are correlated in a call packet delivery application server and then delivered to a CALEA/Legal Intercept monitoring system. Advantageously, the monitoring receives as a bundled message set the bearer message and the control messages used to route and otherwise process these bearer messages.

  • Publication number: 20060060532
    Abstract: A process and system for purifying water is disclosed. For example, in one embodiment, the process may be used to remove a divalent salt, such as calcium sulfate, from a water source in order to prevent the divalent salt from precipitating during the process. The water source, for instance, may be fed to an ion separating device, such as an electrodialysis device. In the electrodialysis device, an ion exchange takes place between the divalent salt and another salt, such as a monovalent salt to produce two concentrated salt streams that contain salts having greater solubility in water than the divalent salt. In one embodiment, the two salt streams that are produced may then be combined to precipitate the divalent salt in a controlled manner. During the process, various other components contained within the water feed stream may also be removed from the stream and converted into useful products. In one particular embodiment, the process is configured to receive a byproduct stream from a reverse osmosis process.

  • Publication number: 20050268784
    Abstract: The invention relates to a gas supply for an electrostatic filter and an electrostatic filter arrangement which has an electrostatic filter and a gas supply. Here, the gas supply has an incoming flow channel of constant cross-sectional area, a gas inlet hood with cross-sectional area expanding in the direction of the electrostatic filter, and an admixture arrangement for a conditioning means, wherein at least one flow distributor is arranged in the expanded cross-sectional region of the gas inlet hood. Characterizing features include a first vortex arrangement generating a leading-edge vortex arranged in the incoming flow channel, a second vortex arrangement generating a leading-edge vortex arranged in the gas inlet hood before the flow divider in the gas flow direction, and the admixture arrangement arranged in the region of one of the two vortex arrangements.

  • Publication number: 20050152961
    Abstract: The present invention relates generally to the preparation and use of biological tissue adhesives which rely on combining fibrinogen and thrombin. More particularly, the present invention relates to a method of preparing a fibrin sealant whereby said sealant is formed by reconstituting the fibrinogen or the thrombin component in the presence of biological and/or non-biological agents such as drugs, chemicals, and proteins. Preferably, these agents are introduced in solution, such as for example, a corticosteroid-containing solution like a betamethasone solution containing betamethasone acetate or betamethasone sodium phosphate; a triamicinolone solution; or a methylprednisolone solution. These solutions may be substituted for, or provided as a complement to, other solutions that are typically used in the preparation of fibrin sealants such as, for example, calcium chloride.

  • Publication number: 20050128703
    Abstract: A method and apparatus for supplying cooling air to electronic equipment from ones of at least two sources. A detector detects whether the quality, such as the temperature of the cooling air from a source, is satisfactory and if not shuts the damper to that source and opens the damper to another source. A main controller provides additional control signals for controlling the dampers to protect the electronic equipment, or for shutting down the electronic equipment.
