Abstract: Le procédé et l'installation de circuit hydraulique permettant de corriger la profondeur de pénétration du poinçon d'une presse-plieuse hydraulique.  Ils permettent une modification de la position des butées, sans que le coulisseau doive être relevé de la pièce usinée.  Les butées y sont provisoirement déchargées par une poussée opposée à celle du coulisseau, poussée contraire obtenue par exemple dans des cylindres à double effet, sans que cesse la pression sur la pièce usinée.  Cela permet un réglage fin de la profondeur de pénétration en une seule opération.  Le procédé est applicable sur des presses-plieuses comportant des moyens mécaniques de limitation de course aussi bien que sur celles comportant des moyens hydrauliques de limitation de course.

Abstract: EXHAUST SEAL RING                 ABSTRACT OF THE DISCLOSURE            The outlet of an exhaust manifold for a transversely mounted vehicle engine is coupled by an articulated connection with the inlet of an exhaust header.  The articulated connection has portions associated with the manifold and header respectively and includes an annular seal ring with a spherical sealing surface thereon.  The sealing surface engages a conical seating surface on the manifold at the urging of a spring between the manifold and header.  The seal ring is composed of many metal wires which are packed together to define the annular structure and thus produce a wear resistant, relatively impervious sealing surface having a slight resiliency to permit good sealing conformation against an imperfectly formed geometric seating surface.

Abstract: ABSTRACT OF THE DISCLOSURE            A coke dry quenching apparatus comprises a vertical chamber in the lower portion of which is disposed a quenching gas feeding means.  The chamber has in its roof a charging hole and in its bottom a discharging gate.  In the walls of the chamber is disposed a plurality of peripheral gas conduits communicated with the inner space of the chamber and with an annular collector having a common gas withdrawal conduit.  According to the invention the hollow of the collector is divided by a horizontal partition provided with ports into two cavities communicating with one another, the lower cavity being communicated with the peripheral gas conduits and the upper one with the common gas withdrawal conduit.        Due to the fact that the pressure of quenching gas in the lower cavity of the collector is equalized, the proposed apparatus ensures that the quenching gas flow rate through all the peripheral gas withdrawal conduits is practically equal, which provides for a uniform cooling of the whole mass of the coke being treated.  This permits the consumption of quenching gas to be reduced, and the efficiency of the process to be raised.

The binary out-put data and desired output times are placed in a self-sorting stack.  Entries are time-ordered based on their respective desired output times.  A real time counter is used in com-paring the stack entries, one-by-one, with real time   The entry with the earliest desired output time, except in the case of an output interrupt, is compared before any other desired output time associated with a byte of output data.  CPU control of the stack is not required and digital computer throughput is increased.  Interruption of the CPU programming is avoided relative to transmission of outputs.

Abstract: Abstract of the Disclosure Under thermal aging conditions of reinforced polymeric materials, some reinforcements are not as effective as others in providing longevity for the fiber rainforced polymeric materials.  A method is provided for incorporating an additional amount of antioxidant into the polymeric mate-rials before the reinforcement is added to the polymeric materials or into an aqueous treating solution for the fibrous reinforcement.  The antioxi-dant is of low volatility and good thermal resistance, and when added to the polymer directly is used in an amount greater than three parts per hundred parts of the polymer (PhR).  When the antioxidant is added to the aqueous treating solution for treating the fibrous reinforcements, the antioxidant is in the form of an oil-in-water emulsion. Oil-in-water emulsions of antioxidants having low volatility and good thermal resistance are provided for treating fibrous reinforcements such as glass fibers.  The emulsions are comprised of the antioxidant in an amount of about 5 to about 60 weight percent of the emulsion along with an organic solvent that has a boiling point above the temperature of use or of preparation and is compatible with the antioxidant in an amount in a ratio of about 0.5 to about 1.5 with the antioxdant and one or more emulsifiers selected from the group consisting of anionic, and nonionic having a combined NLB (hydrophilic/lipophilic balance) in the range of about 12 to about 27.  The emulsion can also contain a resin carrier such as an epoxy resin and/or a stabilizing agent such as polyalkylene polyol. An aqueous Treating solution for treating fibrous reinforcement such as a sizing composition for treating glass fibers to increase the pro-tection of fiber reinforced polymeric materials against chemical degradation due to the chemistry on the treated glass fibers or reaction and/or decom-position products of said chemistry is comprised of the oil-in-water emul-sion, film-former, and coupling agent and may contain other conventional agents used in sizing composition.

Abstract: (Case No. 59-4) ABSTRACT           A hydraulic tensioning device for maintaining a pre-determined amount of tensioning force on an endless drive belt for the vehicle accessories drive system.  A self-contained hydraulic fluid supply and pump assembly is mounted on the swinging end of a pivotally mounted lever and is moved toward the drive belt by a hydraulically actuated piston which is mounted in a fixed position on the engine.  An idler pulley is rotatably mounted on the fluid supply and pump assembly and is engaged with and driven by the drive belt.  The drive belt rotates the idler pulley which hydraulically actuates the piston by driving the pump which supplies hydraulic fluid to the piston from the fluid supply.  The piston pivots the lever toward the belt whereupon the idler pulley engages the belt and exerts the desired tensioning force on the belt.  Check valves in the pump assembly regulate the amount of hydraulic force applied to the piston and ultimately to the belt.  A partition member is slidably mounted within the piston cylinder and compensates for small oil leaks in the piston by reducing the effective volume of the cylinder chamber to maintain a constant tensioning force on the belt tensioning lever when the engine is shut off.
