摘要： A process of recovering cesium ions from mixtures of ions containing them and other ions, e.g., a solution of nuclear waste materials, which comprises establishing a separate source phase containing such a mixture of ions, establishing a separate recipient phase, establishing a liquid membrane phase in interfacial contact with said source and recipient phases, said membrane phase containing a ligand, preferably a selected calixarene as depicted in the drawing, maintaining said interfacial contact for a period of time long enough to transport by said ligand a substantial portion of the cesium ion from the source phase to the recipient phase, and recovering the cesium ion from the recipient phase. The separation of the source and recipient phases may be by the membrane phase only, e.g., where these aqueous phases are emulsified as dispersed phases in a continuous membrane phase, or may include a physical barrier as well, e.g., an open-top outer container with an inner open-ended container of smaller cross-section mounted in the outer container with its open bottom end spaced from and above the closed bottom of the outer container so that the membrane phase may fill the outer container to a level above the bottom of the inner container and have floating on its upper surface a source phase and a recipient phase separated by the wall of the inner container as a physical barrier. A preferred solvent for the ligand is a mixture of methylene chloride and carbon tetrachloride.

摘要： A method of selectively and quantitatively removing and concentrating at least one selected ion from a multiple ion solution in which other ions are present is disclosed. The method comprises(a) bringing a complexing agent for the selected ion(s) into contact with the multiple ion solution to remove and concentrate selected ion(s) from the multiple ion solution, wherein the complexing agent is selected from the group of macrocyclic compounds having at least four --A--CH.sub.2 --CH.sub.2 -- groups in which A is selected from O, O--CH.sub.2, S, S--CH.sub.2, N--R and N--R--CH.sub.2 in which R is selected from H, lower alkyl and benzyl, with the macrocyclic compounds further having a hydrocarbon side chain having an end group ##STR1## in which X is selected from the group consisting of lower alkyl, benzyl, phenyl, halogen, O--CH.sub.3, O--C.sub.2 H.sub.5 and O--M, wherein M is selected from the group consisting of sand, silica gel, glass, glass fibers, alumina, zirconia, titania and nickel oxide;(b) removing the multiple ion solution from which the complexing agent has removed the selected ion(s) from the complexing agent having the selected ion(s) complexed therewith;(c) bringing the complexing agent complexed with selected ion(s) into contact with a receiving liquid to break the complex and remove the selected and concentrated ion(s) from the complexing agent; and(d) determining the concentration of selected ion(s) in the receiving liquid from which the concentration of selected ion(s) in the multiple ion solution can be calculated.

摘要： An apparatus for communicating with mobile receivers for emergency notification and other purposes comprises a localized (low power) transmitter capable of transmitting short bursts of compressed audio or video messages over a selected spatial range. The apparatus further contains a means of measuring the relative speed of the transmitter and receiver(s) and adjusting the transmission accordingly (for example by increasing the output power, shortening the burst length, or increasing the burst repetition rate). In this way, the effective “footprint” of the transmitter and/or the message length is matched to the time the receiver(s) pass within range of the transmitter so that each receiver is able to capture at least one complete burst in the available time. The transmitter may be relatively fixed, for instance on a highway overpass, for communicating with vehicles passing on the highway. Alternatively, the transmitter may be mounted on an emergency vehicle to warn vehicles ahead or on intersecting roads that the emergency vehicle is approaching. In this case, the transmitter may adjust its effective range based on the speed of the emergency vehicle itself.
