Abstract: ABSTRACT:         A subscriber circuit for a telephone network which is coupled to earth via a frequency-dependent coupling circuit.  As for direct current the coupling circuit has a much lower impedance than for alternating current, the electrolytic corrosion due to leakage current in the subscriber line is counter-acted and no sever requirements need to be imposed on the equality of the impedances in the two wires of the subscriber line.

Abstract: Abstract Coating high solids film-forming compositions High solids coating methods and apparatus are disclosed which eliminate many of the disadvan-tages associated with known coating processes.  The techniques disclosed require only a minor amount of a volatile solvent to achieve atomization and applica-tion of a paint or other coating material.  High solids coating compositions containing about 70-99% by weight solids are atomized and coated,  This method also enables polymeric compositions having high molecular weight to be employed as coating materials.          According to techniques described, liquid compositions containing film-forming solids are kept under pressure with a minor amount of a highly volatile solvent of from about 1 to 30% by weight, even as low as about 1-10% by weight, at a temperature above the normal boiling point of the solvent.  Such a composition is then atomized by releasing the pressure upon a stream of the composition at a temperature above the normal boiling point of the solvent and below the minimum foam temperature at atmospheric pressure for the composition.  The film-forming solids are thus con-veyed with or without an external atomizing means.

Abstract: L'invention concerne une bande d'accrochage destinée à être fixée, en cours de moulage, sur un article à mouler, cette bande comportant une semelle dont une face porte des éléments d'accrochage tournés vers l'extérieur du moule, et la bande prenant appui sur la surface intérieure du moule le long d'une zone marginale périphérique dépourvue d'éléments d'accrochage. La bande selon l'invention est caractérisée par le fait qu'elle porte, entre la surface intérieure du moule et sa semelle portant les éléments d'accrochage, une fine pellicule provisoire de protection continue qui recouvre les éléments d'accrochage et qui s'étend jusqu'à la zone marginale pour définir un espace fermé et étanche de protection des éléments pendant le moulage. L'invention permet d'éviter que le produit de moulage, avant sa mise en forme physique et chimique finale, ne se glisse entre la surface intérieure du moule et la bande elle-même pour venir intéresser les éléments d'accrochage tournés vers l'extérieur du moule et se répandre et se fixer entre eux, en inhibant ainsi leur pouvoir d'accrochage.

Abstract: TITLE: DERIVATIZED POLYSTYRENE AND OTHER POLYMER        SUPPORTS FOR SPECTROSCOPIC STUDIES                         ABSTRACT      Molded articles formed of polystyrene or other poly-mers containing an aromatic moiety can be derivatized on the surface of the article by subjecting the molded article to a chemical reaction wherein the reaction media utilizes tetramethylsulfone as the reactant solvent and a suitable substituent group which is substituted on to the aromatic moiety of the polystyrene or other polymer by electrophilic substitution.  By choosing the substituent group to further include a leaving group, further substi-tution of the primary substituent can be effected norm-ally by nucleophilic substitution reaction.  In this way, biologically important molecules can be attached to a polystyrene or other aromatic containing polymer without effecting certain properties of the molded article such as its optical or spectroscopic clarity.

Abstract: TITLE OF INVENTION          A METHOD FOR INSTANTLY KILLING AND COOLING FISH, AND AN APPARATUS          FOR CARRYING OUT THIS METHOD     ABSTRACT OF THE DISCLOSURE         The  method  of killing and preserving fish in a  fresh stateproposed  by this invention is a two stage  procedure.    In the primary or instant cooling stage,  fish are killed  instantly by  the shock of emersion in a rapid cooling fluid.   This  fluid subjects the  surface layer of each fish to a temperature  below that at which they will be stored.   In the secondary or  storage stage,  individual fish are either passively cooled on the inside by  their low temperature surface layer,  or else they are cooled inside and out by external means.         The  fish execution and cooling apparatus proposed  by this invention to realize the above mentioned method is comprised of the following: a rapid cooling hopper to deliver fish into the system,  a primary rapid cooling tank to instantly kill fish, and a device connected to the primary rapid cooling tank to discharge fish  to  the secondary stage cold storage tank.   Live fish  are introduced to the system through the rapid cooling hopper, killed by  the  shock of instant cooling in the primary  rapid  cooling tank,  and  subsequently  delivered to the secondary  stage  cold storage tank by the discharge device.

Abstract: "HYDROCARBON DEHYDROGENATION PROCESS WITH OXIDATIVE REHEAT"                                    ABSTRACT   Dehydrogenatable hydrocarbons such as alkylaromatic hydrocarbons (e.g. ethylbenzene) are catalytically dehydrogenated with minimum produc-tion of thermal   by-products by using several reactors containing de-hydrogenation catalyst in series flow with interstage heating being sup-plied by selective combustion of hydrogen produced in the process.  The selective combustion of hydrogen is performed in a reactor which has a relatively small bed of dehydrogenation catalyst located adjacent to the bed of selective hydrogen oxidation catalyst and which has a flow path such that the entering hydrogen-containing stream first contacts the bed of oxidation catalyst and immediately thereafter contacts the bed of the dehydrogenation catalyst. Thus the stream passed to the reactor is heated to a relatively high temperature in the oxidation bed as exothermic combus-tion of hydrogen and then immediately cooled to a somewhat lower temperature in the small bed of dehydrogenation catalyst by the endothermic dehydrogena-tion reaction.  This sequence of steps shortens the time the reactants are maintained at high temperatures which produce undesired by-products and reduces the temperature of the reactants prior to transport through a conduit to the main bed of dehydrogenation catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE     A first-in, first out data memory minimizes fall-through delay.  The FIFO memory has a plurality of cascaded register stages arranged in sections, with the input of each section selectively coupled to a bypass bus.  Data is introduced on the bypass bus, and control logic writes the data into the section nearest the output which is currently not full.  The individual register stages are self-clocked, so that data is then shifted toward the output through any vacant registers.  In another aspect, the register stages are arranged in sections of different length, with the shortest section closest to the output and the longest section closest to the input.  Decreased fall-through delay is achieved by minimizing the length of the FIFO buffer actually traversed by the data while insuring that the order of the data remains unchanged.
