    Abstract: Techniques are disclosed for fabrication of superconducting thin film structures which show Josephson-like effects and which allow fabrication of standard components, such as resistors and capacitors in circuits, starting with the deposition of superimposed thin films of selected metals at least one of which is superconducting, and all of which are stable (i.e., will not diffuse and are sufficiently inert to be chemically stable under normal use). The thin films are all effectively removed around the desired structure by anodization through a photoresist mask or by ion beam etching. A structure which shows a Josephson-like effect is produced by so manipulating the thin films that a thin line region across a narrowed section of the layered thin films is produced with a lower transition temperature than in the surrounding layered films. This is done by altering the ratio of the thickness of the superconductive thin film to the thickness of the non-superconductive thin film in the thin line region and controlling the dimension, l, of the thin line region in the direction of current flow.

    Abstract: A system for separating organic chemical compounds in an extract consisting of a relatively large volume of solvent in which the compounds are dissolved, comprises a heatable column, packed with an appropriate packing material. The extract is injected into the column after the latter''s temperature is above the vaporization temperature of the solvent. The solvent coming in contact with the heated packing material vaporizes, and the solvent vapors are flushed out of the column, while the compounds are deposited on the packing material and thereby prevented from exiting the column together with the solvent vapors. After complete removal of all solvent vapors, the temperature of the column is raised to above the vaporization temperature of all of the compounds to vaporize the compounds and thereby separate them from the packing material. An appropriate flushing gas transfers the vaporized compounds from the column for direct injection into an analytical instrument, such as a gas chromatograph.

    Abstract: In a magneto-optic readout system, a polarized beam of light from a laser is subjected to the magneto-optic effect of a magnetic record medium, and then passed through an analyzer which resolves the beam into two orthogonal vector components so oriented that the two components are of equal amplitude when the angle of rotation due to the magneto-optic effect is zero. Separate photodetectors produce two output signals which are proportional to the amplitudes of the vector components. The two output signals are combined in a differential amplifier through separate logarithmic transfer circuits to produce an output signal proportional to the ratio of the two original detector signals.

    Abstract: FILLED POLYMER COMPOSITIONS MADE BY DISSOLVING THE POLYMER BINDER IN A SUITABLE SUBLIMABLE SOLVENT, MIXING THE FILLER MATERIAL WITH THE POLYMER AND ITS SOLVENT, FREEZING THE RESULTING MIXTURE, AND SUBLIMING THE FROZEN SOLVENT FROM THE MIXTURE, REMOVING IT THEREFROM. THE REMAINING COMPOSITION IS THEN SUITABLE FOR CONVENTIONAL PROCESSING, SUCH AS COMPRESSION MOLDING OR EXTRUDING. A PARTICULAR FEATURE OF THE METHOD OF MANUFACTURE IS POURING THE MIXED SOLUTION SLOWLY IN A CONTINUOUS STREAM INTO A CRYOGENIC BATH WHEREIN FROZEN PARTICLES OF THE MIXTURE RESULT. THE FROZEN INDIVIDUAL PARTICLES ARE THEN SUBJECTED TO THE SUBLIMATION.

    Abstract: A closed cycle depressurization system including a lamp envelope for containment of a discharge gas at greater than atmospheric pressure in communication with a gas storage and depressurization chamber. A substantially transparent material, potentially frangible at said pressure forms at least a portion of the envelope. In one embodiment, depressurization is effected by externally cooling the walls of the chamber and in a second embodiment the chamber contains a gas adsorbent which adsorbs gas to reduce the pressure in the lamp envelope to the desired safe nonoperating level. Repressurization is accomplished by raising the temperature of the chamber and the stored gas and recycling the gas to the envelope.
