Abstract: A hooking device attaches an equipment like a fall limiter to an anchorage structural element by means of a stick. The device comprises an elongated member to which the equipment is attachable. A hooking head slides along the elongated member. The hooking head has a hook forming an opening in which the anchorage structural element is engageable. An actuating mechanism operates a locking element of the opening in response to a sliding of the hooking head with respect to the elongated member. A stick detachable fastening element is used to slide the hooking head with respect to the elongated member in response to a movement of the stick when the anchorage structural element is engaged in the opening.

Abstract: According to the invention, the position sensor is characterized in that the correction means (3) are achieved by at least one saturated magnetic pole, a so-called stabilization pole (Ps), having a sign opposite to the sign of the irregular pole (Pi) which is also saturated, each stabilization pole (Ps) extending from one to the other edge of the magnetic ring, by being inserted in the irregular pole, so as to stabilize the magnetic signal delivered by the passage of the poles adjacent to the irregular pole, said magnetic signal delivered between the passage of the adjacent poles not passing through the zero value.

At least the detection cell located in relation to a magnetic track with a singular pole is a single-element detection cell, and the generator elements of the magnetic tracks and the detection cells are arranged in dependence on the logical processing resources such that the digital output signal has the same constant period, both on its regular coding part and on its irregular coding part, and the regular coding part and the irregular coding part have cyclic ratios that are unbalanced and different from each other.

Abstract: The invention concerns a position sensor in which the irregular pole includes resources for correcting the value of its magnetic field so as to stabilize the differential signal in such a way that the part of the differential signal taken at the passage through zero, and located between the parts of the differential signal corresponding to the passages of the adjacent poles, has a slope whose value, in absolute terms, is more-or-less identical to the values of the slopes of the parts of the differential signal obtained at the passage through zero and corresponding to the passages of the other poles.

Abstract: A magnetic sensor including a first resource (3) for the creation of a magnetic field, oriented along a first axis in the direction of the axis of movement, and a second resource (6) for the creation of a magnetic field, oriented along a second axis in the direction of the axis of movement, opposed to the first direction. The first and second field-creation resources are mounted opposite to each other in order to form, between them, a magnetic measuring gap in which the measuring element that is sensitive to the value of the magnetic flux generated by the first and second field-creation resources is located, with the measuring element or the first and second field-creation resources being linked to the mobile object.

Abstract: A high-voltage homogeneous co-curing composite insulator includes first and second end fittings longitudinally separated by a spacer, a resin impregnated fiber core wound onto the end fittings and onto the spacer, and an outer sheath moulded onto the fiber core. Since the resin matrix of the core and the material used to form the outer sheath each include curable resins from the same family and are, therefore, chemically compatible, a chemical link exists between these two elements. The end fittings are provided with a relatively thin wall defining a mechanical fuse.

Abstract: A high-voltage bushing for insulating a conductor going through a metallic wall is described herein. To allow a conventional current transformer to be used to monitor the current flowing through the conductor, an external shield is embedded in the tubular body of the bushing and electrically connected to the metallic wall. An internal shield, also embedded in the tubular body of the bushing and electrically connected to the conductor, is provided to prevent the electric field to generate high levels of partial discharge in the air surrounding the conductor in the tubular body.

Abstract: A double-walled container for transporting and storing a liquified gas or cryogenic liquid at low temperature. The container has an inner liquified gas holding vessel and an outer shell enclosing the inner vessel. The outer shell is coaxial with the vessel and of such a size as to provide a closed insulated space all around it. The inner vessel is suspended by its ends within the outer shell, with one end of the vessel being rigidly connected to the adjacent end of the shell while the other opposite end of the vessel is slidably connected to the other adjacent end of the shell so as to allow thermal expansion of the inner vessel and outer shell with respect to each other. Closable feeding and exit pipes pass through the outer shell and the inner vessel for introducing and draining the liquified gas into and off from the inner vessel. This container is light weight and can be of very great size; it can be used for the international transportation of liquid hydrogen by air, sea, rail or road.
