Abstract: Procédé et équipement de contrôle continu de vitesse pour véhicule moteur piloté automatiquement ou manuellement, tel qu'un véhicule ferroviaire, dont la voie parcourue est divisée en cantons successifs.  On transmet au véhicule, dès son entrée dans un canton donné, la vitesse limite qui lui est imposée à la sortie de ce canton et dénommée "vitesse de sortie", on garde en mémoire cette vitesse dans la cabine de conduite du véhicule et on la compare à la vitesse de sortie du canton précédent, vitesse que l'on a gardée en mémoire.  On mesure en permanence la vitesse et la décélération réelles du véhicule. Dans un premier cas où la vitesse de sortie du canton donné est au moins égale à la vitesse de sortie du canton précédent, on déclenche un freinage d'urgence, après une temporisation donnée, dès que la vitesse réelle du véhicule devient supérieure à la vitesse de sortie du canton donné.  Dans-un second cas où la vitesse de sortie du canton donné est inférieure à la vitesse de sortie du canton précédent, on déclenche un freinage d'urgence, après une temporisation donnée, dès que la décélération réelle du véhicule devient inférieure à une décélération donnée.

Abstract: SOLENOID               Abstract of the Disclosure A wet plunger solenoid is formed with a three-piece spool assembly including a base and a hub joined by a non-magnetic sleeve.  An electric coil is wound directly onto the sleeve to compress the sleeve about the telescopically interfitted base and hub parts to form a fluid-tight joint, thus forming an armature or plunger cavity which has high resistance to deformation when fluid pressure is applied to the interior.  A fluid-tight joint is formed which is free of threaded connections and is reinforced by reason of the fact that the coil is wound in tension, and the cumulative compression effectively joins the parts into a unitary structure.

Abstract: ABSTRACT      The process of the invention can be practiced with coated and uncoated pipe, although the process hag particular utility for coated pipe.  The pipe joint made with the process of this invention involves coupling a pin section to a bell section. When formed, the joint has a cylindrical, mechanical inter-ference section that is followed by a substantial, conical, non-interference section whose opposite walls are chemically sealed to each other.  The conical section of the pin is first coated with a flexible adhesive.  Then by telescoping the pin inside the bell, the flexible adhesive becomes extruded from the cavity between the bell and the pin, to thereby automatically form a ring which completely covers the mouth of the joint.  The ring bridges the gap between the coated sections of pipe, there-by providing a continuous coating throughout the connection. Thus, for internally-coated pipe, there is provided a completely-coated run of pipe inclusive of the joint.

Abstract: Abstract of the Disclosure A  hydraulic reactor system for minimizing mooring forces of a vessel attached to an offshore structure, by means of a ramp which enables access between the two, comprising a structural frame provided with a hydraulic piston utilizing a one-way pressure relief valve which allows inward movement with minimal resistance.  Conversely, the outward movement of the hydraulic piston provides considerable resistance.  The device is connected to, or involved in, a ramp structure allowing an extension or reduction in length of the radius of the geometric configuration as it pivots vertically when attached to a vessel on its outboard end.  The upward movement energizes the system by compressive action with minimal resistance, while the downward movement pro-duces considerable resistance to outboard movement of the vessel.       This vertical movement of the vessel caused by the waves produces reaction forces in a direction against those elements such as wind, waves and current that would tend to cause horizontal movement of the vessel.  It is this process of gently nudging the boat in an up weather direction, with each of its downward movements, the causes an interial reaction that overcomes the forces of the envir-onment with minimal effort.  The device can be pivotally attached to a mooring point, known as a "king post", allowing the device and attached ramp/vessel to "weathervane" about the "king post" responsive to changes in direction of the mooring forces.

Abstract: A HEALD, A METHOD FOR THE MANUFACTURE THEREOF AND A DEVICE FOR BUNDLING SUCH HEALDS            Abstract of the disclosure A plurality of healds of thread material are in hand looms stacked on shafts for providing the shed of the loom. These healds have been produced by manually tying knots on a double-folded thread. The manual tying is a time-wasting job and the knots, which are considerably thicker than the thread material will, when some thousand healds are stacked side by side on the shafts, form bosses which will give a non-uniform width to the stack of healds.            These problems are all eliminated by a novel heald of a textile thread material wherein the twisted or plain thread of the hitherto known thread healds has been substituted by two crochetted threads, and where each one of the knots which in the hitherto known thread healds connect the two thread parts for forming the heald eyelet are replaced by interconnecting ladders of two adjacent loops in the two crochetted threads, said novel heald being produced in a hosiery machine in a continuous length and thereupon being arranged in bundles in an automatic bundling machine.
