Abstract: The ice spike for mountaineering is composed of a front frame and a rear frame joined to one another by a joining strip which comprises two parallel rows of holes spaced at regular intervals. Lengthwise adjustment of the ice spike is performed by the joining strip and a stud designed to be inserted in one of the holes of one of the two rows of the joining strip. The holes of the second row are offset longitudinally with respect to those of the first row, this enabling the length of the spike to be adjusted by one shoe size or by half a shoe size.

Abstract: An ice crampon for mountain climbing comprising a reinforcement 12B with a metal reinforcement, fitted with anchoring teeth 14, and a fastening device 30 comprising a lateral operating lever 32 forming a toggle joint for locking or unlocking the heel of the shoe along the pivoting direction of the operating lever 32.

Abstract: A portable lighting lamp comprises a housing containing a lighting module with light-emitting diodes, an electric power source by means of batteries, and a switch for control of lighting of the light-emitting diodes. The housing comprises an intermediate support made of insulating plastic material which is equipped with a securing device on the front wall for fitting of the lighting module, positioning means imbricated on the two opposite sides between contacts in electrical connection with the light-emitting diodes and the batteries, and recesses on the rear wall for housing the batteries between the contacts.

Abstract: A portable electric torch with a double lighting includes a housing containing a first bulb associated to a first reflector, an actuating ring movable in rotation to perform both control of the lighting circuit of the bulb and adjustment of the focusing sing by relative movement of the bulb and reflector in translation. The lighting circuit includes a first disconnecting gap designed to be open or closed for switching the first bulb off and on, and in addition a second disconnecting gap for power supply of a second bulb when the actuating ring is in a preset angular position.

Abstract: A belaying descending device for climbing or mountaineering,

Abstract: A draining wall includes a plurality of panels filled with a granular filtering material and separated from each other by intermediate elements cast in the ground, a member, embedded in the lower part of each intermediate element, enabling communication to be established between the panels of each pair of adjacent panels, and auxiliary devices applied into contact with the end faces of the intermediate elements so as to cover the mouth of the communication-enabling members. Each auxiliary device is open on the side applied against the intermediate element, has a height greater than the diameter of the mouth, delimits a volume around the mouth, and has either perforations over at least a part of its surface whose size is smaller than that of the granules constituting the filtering material or an opening to which a perforated pipe acting as a receiver is connected.

Abstract: The invention relates to the processing of the multiple paths in an interrogator station which, in response to a salvo of interrogations, receives responses in the form of pulses. The station comprises at least two reception channels. The responses to each interrogation of one and the same salvo are classified by order of appearance. A value of dispersion of the energies is estimated, for each channel and each salvo, on the responses having the same classification. Since the first classified response is, by assumption, considered to have arrived by a direct path, the following responses will be eliminated, on the grounds that they have been received after passing through multiple paths, if their values of dispersion of energy on the two paths are not equivalent to those of the first response.

Abstract: A snap-hook comprises a pivoting finger with a rotary locking ring cooperating with a locking bolt. This bolt has an operating component designed to cooperate alternately with a hole or a notch arranged in the locking ring with a preset angular offset, respectively in the first locked position to perform said positive locking of the ring in rotation when the operating component is inserted in the hole, and in a second unlocked position with formation of an internal link with a hang-up between the ring and finger when the operating component engages in the notch, moving from the second unlocked position to the first locked position being performed manually by a rotational movement of the ring causing the hang-up to be released at the beginning of travel following the reaction of the ring on the operating component, and insertion of the operating component in the hole at the end of travel for positive locking of the ring in rotation.

Abstract: A snap-hook comprises a pivoting finger, associated to a locking ring movable in rotation between a first locking position and a second unlocking position. A locking bolt cooperates with the ring to lock the latter positively in the first position.

Abstract: The end piece for passage of an electrical power supply cable through an orifice of a casing comprises a flexible bearing flange cooperating with an auxiliary securing part arranged as a hollow button having a clamping surface in the shape of a rigid wedge bringing about elastic deformation of the flange, and progressive clamping of the cable when the button moves from a released position to a secured position. The securing part of the passage is an integral part of the insulating wall supporting the contacts.
