Abstract: The invention is a reconditioner for batteries to remove the “memory effect” or “voltage depression”, which is caused by the failure to completely discharge a battery before recharging the battery. The invention places a closed circuit with a low resistance between the positive and negative terminals of a battery. A threshold device is used to stop the current flow after the battery is discharged to a certain level. Some embodiments of the invention provide an indicator to indicate when a battery is sufficiently discharged. Other embodiments also provide a recharger, which recharges the battery after the battery is sufficiently discharged.

Abstract: Compositions and methods for selectively binding metal ions from a source solution comprise using a polyhydroxypyridinone-containing ligand covalently bonded to a membrane support having the formula M—A—L(HOPO)n. M is a membrane having a hydrophilic surface, A is a covalent linkage mechanism, L is a ligand carrier, HOPO is a hydroxypyridinone appropriately spaced on the ligand carrier to provide a minimum of six functional coordination metal binding sites, and n is an integer of 3 to 6. The separation is accomplished by passing a source solution containing the ions to be separated through a cartridge containing the membrane-ligand composition, causing the selected ions to be complexed to the HOPO ligands and subsequently removing the selected ions from the cartridge by passing an aqueous receiving solution through the cartridge and quantitatively stripping the selected ions from the HOPO ligand.

Abstract: A method for removing, separating, and concentrating certain selected ions from a source solution that may contain larger concentrations of other ions comprises bringing the source solution in contact with a composition comprising an ion-binding ligand covalently bonded to a membrane having hydrophilic surface properties. The ligand portion of the composition has affinity for and forms a complex with the selected ions, thereby removing them from the source solution. The selected ions are then removed from the composition through contact with a much smaller volume of a receiving solution in which the selected ions are either soluble or which has greater affinity for the selected ions than does the ligand portion of the composition, thereby quantitatively stripping the complexed ions from the ligand and recovering them in concentrated form in the receiving solution. The concentrated ions thus removed may be further separated and recovered by known methods.

Abstract: An electron accelerator includes a vacuum chamber having an electron beam exit window. An electron generator is positioned within the vacuum chamber for generating electrons. A housing surrounds the electron generator and has a first series of openings formed in the housing between the electron generator and the exit window for allowing electrons to accelerate from the electron generator out the exit window in an electron beam when a voltage potential is applied between the housing and the exit window. The housing also has a second series and third series of openings formed in the housing on opposite sides of the electron generator for causing electrons to be uniformly distributed across the electron beam by flattening electrical field lines between the electron generator and the exit window.
Abstract: Methods for marking a liquid and methods and systems for identifying marked liquids. A liquid can be marked for identification purposes with at least a first marker and a second marker. Each of the markers is miscible with the liquid. The markers are mixed in the liquid so that the ratio of the concentration of the first marker to the concentration of the second marker is substantially equal to a predetermined value. Thus, when a system according to the invention measures the concentrations of the first and second markers, the system can compare the ratio of the measured concentration of the first marker to the measured concentration of the second marker with a look up table of the predetermined values to provide information concerning the identity of the liquid. In a preferred embodiment, the concentration of the markers is measured using an absorption spectrometer.

Abstract: There is disclosed a process for forming aluminide diffusion coatings containing reactive elements on metal substrates such as iron, nickel or cobalt based alloys for protection against high temperature oxidation or corrosive environments. The process includes depositing a mixed metal coating containing aluminum and at least one reactive element onto the metal substrate and heat treating the coated substrate to induce interdiffusion of elements between the substrate and the deposited metal coating. In one aspect of the invention, the reactive element is yttrium and the metal coating is deposited by ion plating yttrium-aluminum by thermal evaporation from a yttrium-aluminum source. The coated substrate is heat treated between 500.degree.-1200.degree. C. to form a reactive element modified-aluminide diffusion coating having a thin outer Al.sub.2 O.sub.3 coating formed thereon.
Abstract: A system and method for automatically routing telephone calls to a subscriber selected from a group of subscribers having a common calling number. The system and method are directed for use in a local exchange portion of an Advanced Intelligent Network (AIN). A database in electrical communication with the system is operative to store a plurality of user calling numbers and corresponding location data as well as a unique destination number for each of the subscribers and corresponding unique location data. A service control point or adjunct processor in electrical communication with the database processes the call handling request signal to select one of the destination numbers to route the call to. The processing requires determining the user calling number from the call handling request signal, determining the user location data and comparing the user location data to the appropriate subscriber location data to select a corresponding destination number.

Abstract: A method for the removal, separation, and concentration of cesium cations from a source solution which may contain larger concentrations of other alkali metal ions comprises bringing the source solution into contact with a polymeric resin containing poly(hydroxyarylene) ligands. The poly(hydroxyarylene) ligand portion(s) of the polymeric resins has affinity for cesium, thereby removing cesium from the source solution. The source solutions from which the cesium has been removed may then be treated or disposed of as desired and the cesium cations are then removed from the polymeric resin through contact with a much smaller volume of a receiving solution in which these cesium cations are soluble and has greater affinity for such cations than does the poly(hydroxyarylene) ligand or protonates the ligand, thereby quantitatively stripping the completed cesium cations from the ligand and recovering them in concentrated form in said receiving solution.

Abstract: An electronic document processing system is disclosed for a communications network, wherein the network protocol has the property of repeatingly breaking down each established communication connection between network nodes attempting to carry on a dialog session. Related document data is exchanged between a network server and a client node, wherein the network communication connection between the server and the client must be repeatedly re-established and the prior dialog session context must be reassociated with continued dialog session communications between the server and client. Accordingly, the server node embeds a dialog session identifier within each communication to the client so that a response from the client may return the identifier thereby allowing the server to associate new client input with previously stored input related to the dialog session.
