Abstract: A user anonymously acquires a first sequence of encryption key material. An encryption server, having a second sequence complementary to the first sequence, receives and forwards encrypted messages and monitors utilization of encryption key material by the user. As the key material is used, the server adjusts user accounts to exhaust the first sequence. Thus, the first sequence provides for secure, anonymous communication and, correspondingly, can serve as a payment media for conducting electronic transactions.

Abstract: A reduced risk income producing property methodology that allows ownership in property shares by an owner-promoter, by a lessee(s) and lender(s). Risk is reduced by providing a lower risk to all parties and allowing ownership while also allowing reinvestment of profits back into the equity of the property with an additional option of excess profits made available to begin an additional building construction.

Abstract: 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.

Abstract: The invention is a process of selectively and quantitatively removing and concentrating at least one selected ion prosent in low concentration with other ions in higher concentration in a multiple ion solution. The method comprises bringing a complexing agent for the selected ion(s) into contact with a different determined quantity of said multiple ion solution to remove and concentrate the selected ion(s) from the multiple ion solution; removing the multiple ion solution, from which the complexing agent has been removed, the selected ions from the complexing agent having the selected ion(s) complexed therewith, bringing the complexing agent complexed with selected ion(s) into contact with a determined quantity of receiving liquid to break the complex and remove the selected and concentrated ion(s) from the complexing agent therein, and determining the concentration of selected ion(s) in said receiving liquid from which the concentration of selected ion(s) in the multiple ion solution can be calculated.
