Abstract: A terminal, in particular for electronic printed circuit boards, with which contact can be made with the printed circuit board in a materially connecting fashion. In order to obtain, in a terminal arrangement of this type, a more suitable, simpler and statically stable means of making contact, the terminal has at the bottom a planar, solderable bottom face as connecting face, and the printed circuit board has a corresponding, metallized area as solder face only on its upper side to which the terminal can be soldered.

Abstract: A superconductive energy storage system comprising a magnetic field surrounding a superconducting coil having large currents circulating therein, cooling said coil to superconducting temperatures, starting said circulating current in said superconducting coil inductively by a small primer coil, transmitting additional energy into said energy storage system utilizing a laser beam, and retaining said energy in said energy storage system until needed.

Abstract: A method for preparing a nonflammable insulating sheath on a metal conduc wherein the sheath does not shed, slough off, wipe off, or crack when said conductor is flexed or bent comprising the steps of adding impurities to a metal electrical conductor, zonally annealing said conductor, and rectifying said conductor metallurgically by exposing said conductor to a magnetic or electrical field. The method yields a resultant sheathing on said conductor that does not burn, smoke, smolder, yield toxic fumes or crack during bending or flexing.

Abstract: A superconducting switch or bistable device comprising a superconductor in a cryogen maintaining a temperature just below the transition temperature, having a window of the proper optical frequency band for passing a laser beam which may impinge on the superconductor when desired. The frequency of the laser is equal to or greater than the optical absorption frequency of the superconducting material and is consistent with the ratio of the gap energy of the switch material to Planck's constant, to cause depairing of electrons, and thereby normalize the superconductor. Some embodiments comprise first and second superconducting metals. Other embodiments feature the two superconducting metals separated by a thin film insulator through which the superconducting electrons tunnel during superconductivity.

Abstract: Organic compounds exhibit superconducting-like behavior, as to magnetic and lectrical properties, at elevated temperatures above 21.degree.K, where 21.degree.K is the transition temperature of most known metallic superconducting materials. The structure of the organic materials according to this invention is a plurality of superconducting clusters, forming islands within a matrix of insulating material. The ratio of the clusters to the matrix material is a minimum at 1:10.sup.4. The organic compound comprises two distinct atomic groups termed an R group and COOM group combining as R--COOM with the COOM group clustering to form superconducting islands, within the R material matrix.
