Abstract: ABSTRACT     HIERARCHICAL COMPUTER SYSTEM FOR GENERATING         SELECTIVE OUTPUT SIGNALS IN RESPONSE TO                RECEIVED INPUT SIGNALS     Hierarchic three-level computer system for receiving input messages from signal sources and for conditionally activating output devices according to input messages; the system comprising a central computer, a terminal computer and a number of micro computers.  The central computer enters condition tables into specific display memories within the terminal computer.  These tables can be displayed on the terminal computer screen  and may be updated from the terminal computer keyboard.  The micro computer receives input signals from a signal source and composes input messages, which are transferred to the terminal computer.          The terminal computer makes a comparison between input messages and condition table data and selectively activates the output devices.    A specific up and down counting apparatus within the micro computer makes it possible to detect signals and process data simultaneously.

Abstract: ABSTRACT OF THE DISCLOSURE         A high-impedance four-wire temperature-sensing system for a microwave oven is comprised of a thermistor or other sensor and four leads, such that a constant current is provided to the sensor via two leads and the voltage across the sensor is read via the other two leads.  The sensor and the leads have microwave surface resistivity much higher than impedance levels in microwave ovens, so that negligible microwave energy is coupled to the sensing system.  The high-resistance leads in a rigid probe to be inserted into food and in a flexible cable are electrically-conductive iron oxide magnetic tape or are deposited conductors.

Abstract: ABSTRACT OF THE DISCLOSURE        Improved adhesive compositions for laminating plas-tic and particularly vinyl films to metal are described which contain about 15 to 30 percent by weight of a phenolic resol having a methylol content of about 15 to 50 percent by weight, about 25 to about 40 percent by weight of certain nonfunction-al polyurethanes having a molecular weight of at least 20,000 and preferably 60,000 to 300,000 and about 35 to 55 percent by weight of a vinyl solution polymer, all in an organic sol-vent.  The nonfunctional polyurethanes are thermoplastic poly-esterurethanes devoid of reactive isocyanate and hydroxyl groups and are derived from monomeric polyisocyanates and poly-hydroxy compounds chain-extended with x low molecular weight diol, preferably a cycloaliphatic diol, to the desired molecu-lar weight.  When the polyhydroxy compound is a polycaprolac-tone polyol, it is essential that chain extension be effected with a cycloaliphatic diol, preferably dimethylolcyclohexane.        When the polyhydroxy compound is a polyester polyol other than polycaprolactone polyols, it is essential that the polyester be derived from a polycarboxylic acid component comprising at least 30 mol percent, based on total mols of polycarboxylic acid employed in preparing the polyester, of at least one aromatic carboxylic acid.  Polycaprolactone polyols can also be reacted with a polycarboxylic acid component comprising at least 30 mol percent aromatic polycarboxylic acid, in which case chain extension need not be effected with a cycloalipha-tic diol.  Especially preferred thermoplastic polyurethanes are obtained from the condensation of monomeric polyisocyan-ates and polyester polyols having an aromatic polycarboxylic content of at least 30 mol percent chain-extended with low molecular weight cycloaliphatic diol.  The adhesives have ac-tivation temperatures as low as about 260°F. (ca. 125°C) which makes these particularly suitable for laminating vinyl films of 6 mi1s thickness or less to metals without distortion or loss of any embossing or printed decoration on the film.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the recovery of uranium values from uranium-containing material which also contains iron, arsenic and siliceous matter, includes leaching the uranium-con-taining material in aqueous sulphuric acid solution under conditions to provide dissolved iron present in the resultant leach solution as predominantly ferrous iron rather than ferric iron and/or to provide a sulphuric acid concentration in the leach solution sufficiently high to substantially prevent the precipitation of arsenates.  Uranium values are recovered from the leach solution by solvent extraction agent which has little affinity for arsenic.

Abstract: ABSTRACT                  "IMMUNASSAY OF PROTEINS"           In the immunoassay of a particular protein in a biological fluid, there is frequently interference in the assay by other proteins present  in the fluid, e.g. by complement factors or antibodies in human serum.  The interference so caused can be avoided by subjecting the fluid to protein-digestion, using for example an enzyme such as pepsin, as   result of which the particular protein of interest, or a fragment thereof, can be assayed without interference by the other proteins.  Also, radioallergosorbent tests for particular IgE anti-bodies can be improved in sensitivity and accuracy, by subjecting the absorbed IgE to enzymic digestion, and then assaying a fragment thereof.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided herein for the manufacture of metallic magnesium. A mixture of a first quantity of magnesium oxide, a second quantity of a car-bide-forming material, which is either a material selected from the group con-sisting of calcium,  aluminum, boron, silicon, calcium oxide, aluminum oxide, boron oxide, and silicon oxide, or is a mixture of two or more of these materials and whose weight is 10% or less than the weight of the first quantity, and a third quantity of carbon which is at least the equivalent mol weight of that of the magnesium oxide plus the carbide-forming material, is heated within a reducing furnace at a pressure between 5 and 200 torr and at a temperature of at  least 1600°C.  In the furnace there are two reactions, namely a first reaction  to generate carbide from the selected carbide-forming material and the carbon, and a second reaction to reduce the magnesium oxide by the carbide, thereby generating magnesium vapor while regenerating the carbide-forming material.   The magnesium vapor is rapidly cooled by adiabatic expansion to generate metallic magnesium, while the carbide-forming material returns to oxide form.  The carbide-forming material is recycled again, repeatedly, to form carbide and repeatedly to reduce more magnesium oxide.
