Abstract: ABSTRACT OF THE DISCLOSURE The subject of this invention is a method of catalytic hydrogenation of benzene to cyclohexane in gaseous phase on solid catalysts consisting of an active metal and/or oxide thereof, deposited on carriers.  The essence of the invention is obtaining cyclohexane with suitable purity as a result of passing a mixture of benzene vapour and hydrogen, containing even a small, in relation to the stoichiometric composition, excess of hydrogen, successively through a catalyst bed containing platinum or palladium, and through a catalyst bed con-taining nickel.  This makes possible a complete hydrogenation of benzene with a single evaporation of the raw material and without circulation of gases, whereby there are no limitations relating to the upper limit of pressure for conducting the method so that the pressure at which the hydrogen is supplied may be employed.

Abstract: ABSTRACT A method of producing gaseous oxygen comprises the steps of fractionating dry compressed air in a distillation system (9) having a high pressure column (8) operating at between 4 and 8 bars guage and a low pressure column (15) operating at between 0.2 and 2 bars guage. Liquid oxygen is withdrawn from the bottom of the low pressure column (15) through line (40) is pressurized by static head and/or a pump (41) and is evaporated in vessel (43) against a stream (27) of substantially pure nitrogen which has been removed from the top of the high pressure column (8) and compressed to such a pressure that it is at least partly liquified by the evaporation of the oxygen. At least part of the liquified nitrogen formed in vessel (43) is expanded and is returned to the high pressure column (8) as reflux.

Abstract: BLANK FOR THE MANUFACTURE OF EXTRUDING AND                 TAPPING SCREW                     A B S T R A C T      Disclosed is a screw blank used in the formation of an extruding and thread-forming screw fastener which includes a shank with an enlarged head at one extremity,  The shank is comprised of a substantially cylindrical upper portion of a predetermined diameter adjacent the head of the blank and a lead portion formed at the extremity opposite the head.         The largest diameter of the lead portion is less than the predetermined diameter of the upper shank portion, and an intermediate, transition shank portion between the lead and the upper shank portions includes a pair of dissimilar partially frustoconical tapering regions forming two opposing, peripheral segments of the transition portion located on either side of a plane extending longitudinally of the blank.          A first of the two opposing peripheral segments merge with the upper shank portion along a juncture line lying on a plane transverse of the shank which is disposed at an acute angle downwardly relative to a plane extending perpendicularly to the longitudinal axis of the blank.  The lowermost region of the first of the two segments extends downwardly on the shank a distance from the head which is greater than the extent of the lowermost region of the second of the two segments.  The angle of taper of at least the first of the two periphery segments relative to the longitudinal axis of the blank is generally 6°, so that a single lobular region is created on a blank which facilitates the formation of a screw with a thread-forming region which has a plurality of partial threads on the lobular region and an absence of threads on the opposing peripheral side of the screw which therefore minimizes the drive torque to apply a screw of this type.

Abstract: CARRIAGE LOADING ARM ASSEMBLY HAVING TWO MAGNETIC TRANSDUCERS FOR A DOUBLE SIDED FLOPPY DISC                   ABSTRACT OF THE DISCLOSURE      This invention relates to an apparatus for supporting two magnetic transducers on both sides of a magnetic disc.  Prior art apparatuses have either failed to keep both transducers in contact with the disc or have been subject to high rates of wear.  The apparatus of the present invention includes a carriage having a first transducer coupled at one end through a differential torsion spring support which supports the first transducer against one side of the media in a semi-compliant relationship about the axes which are radial and normal with respect to the disc, and in a fully compliant relationship with low flexure stiffness about the third axis which is circumferential with respect to the media. A second transducer is supported on the opposition side of the disc through a gimbal support, which supports the second transducer in a fully compliant relationship with low flexure stiffness in all three axes.

Abstract: ABSTRACT A signal generator featuring, in one aspect, a clock, a programmable device for counting signals from the clock and providing outputs at predeter-mined counts, a delay line for providing a timing signal after a predetermined delay following each output, the delay line having a resolution higher than that of the clock, and a programmable device for repeatedly incrementing the delay for successive timing signals to provide a timing signal period not nec-essarily an integer multiple of the period of the clock.  Preferred embodiments feature an additional delay line for delaying the output of the clock to pro-vide sequences of clock signals having the same period as the clock output but shifted in time so that each timing signal occurs simultaneously with a clock signal, an additional counter connected to be clocked by the clock signals and reset by the timing signals, and a device controlled through the counter for generating timing edges with a resolution equal to that of the delay line.

Abstract: L'invention est relative à un circuit de contrôle de l'alimentation d'une électrode enrobée, de type enrobé par exemple utilisée dans une opération de soudage (SMAW) à arc électrique, enrobée pour protéger l'utilisateur contre les chocs électriques, et qui est destiné à protéger les soudeurs contre les chocs électriques en abaissant la tension en circuit ouvert entre l'électrode et la pièce à souder. L'alimentation peut être à courant alternatif ou continu. Le circuit comporte une source de tension à impédance élevée appliquée à l'électrode, un circuit de détection déterminant la valeur de l'impédance existant entre l'électrode et la pièce à souder, qui compare cette impédance détectée à une impédance seuil et qui génère un signal de contrôle lorsque l'impédance détectée est inférieure à l'impédance seuil. Ce signal de contrôle, lorsque émis, met en fonctionnement un circuit d'excitation qui active alors un dispositif d'alimentation montée en série entre le bloc d'alimentation de l'électrode et l'électrode elle-même, ladite impédance seuil étant fixé à 500 ohms afin de prévenir tous chocs électriques quand un corps humain humide fait contact entre l'électrode et la pièce à souder.

Abstract: ABSTRACT OF THE DISCLOSURE:            A tissue adhesive based on human or animal proteins con-tains factor XIII, fibrinogen and an antibiotic. In order to achieve a high straining capacity of the adherences and a retarded antimicrobial efficacy, the ratio of factor XIII to fibrinogen, expressed in units of factor XIII per gram of fibrinogen, amounts to at least 500. The antibiotic is chosen among aminoglucosides, betalactams, polypeptides or tetracyclines. In a method of producing the tissue adhesive the concentration ratio of factor XIII to fibrinogen is adjusted in a fibrinogen-containing blood plasma fraction by the addition of factor XIII. The antibiotic is added either before deepfreezing or lyophilization of the result-ing preparation, or after thawing or reconstitution of the same.
