Abstract: Methods and systems for encoding encrypted monetary values onto transfer vehicles include one or more payment, encoder, and encrypter devices, and, associated with each designated receiving device such as a wireless telephone, a reader, decoder, and decrypter device for deciphering the data from the transfer vehicles, and, under appropriate conditions, for transferring the monetary values encoded and encrypted on the transfer vehicle into memory associated with the designated receiving device. Once such monetary values are transferred to the receiving device, the transfer vehicle cannot be used to transfer the same monetary value again even though the transfer vehicle is not modified during the transfer process.

Abstract: An alkyd resin comprising a polymerized product of from 25 to 40 percent by weight of trimethylolpropane diallyl ether, from 15 to 30 percent by weight of aromatic acid, from 20 to 40 percent by weight drying compound and from 7 to 16 percent by weight polyol.The invention also includes solutions and dispersions of the resin of the invention and coatings made from the resin or solutions or dispersions thereof.The resin is characterized by being compatible with solvents such as mineral spirits and having good drying properties and being able to form strong flexible films which are resistant to yellowing, and which have low water sensitivity.Prior to the present invention, a non-yellowing alkyd resin having such a combination of properties was unavailable.

Abstract: Compositions which contain one or more aluminum complexes, which find use in coatings, films, paints, lacquers and varnishes, are formed by reacting the aluminum complex with a nonfunctional resin. The nonfunctional resins have neither carboxyl nor hydroxyl functionality, yet react rapidly to form films in conjunction with the aluminum complexes.

Abstract: The present invention is a novel electrochemical process for separating and/or purifying the components of mixed materials such as alloys, rare earths, spent reactor fuel rods, isotopes, or other normally difficult to separate materials which carry the same sign of the ionic charge when in solution (positive, negative or neutral), but which can be made to exhibit a difference in oxidation potential, comprising (a) passing a current through an electrolyte containing the dissolved materials to be separated (separants), carrier-formers and a solvent and (b) refluxing the separants, until the desired degree of purity is reached. The carrier-formers, which may carry a positive, negative or neutral charge, are capable of interacting with the separants to form separant-carriers such that for each separant there is at least one separant-carrier having a positive charge and one separant-carrier having a negative charge, such that each separant is divided between a pair of oppositely directed carriers.

Abstract: A latching device detachably holds a flexible barrier across the exit opening of a contestant's stall. In response to a signal, the latching device releases the barrier and a timing device is activated. Disengagement of the barrier by the contestant prior to the signal activates a penalty indicating device.
