Abstract: This invention relates to a system and a process for the removal of bulk material from a container, in particular, from a box-shaped transport container. In order to be able to suction the bulk material off in a simple and reliable manner out of the transport container, one first of all attaches to an outlet area of container (10) a removal instrument (23) that has a conveyance device. This conveyance device conveys the bulk material in the removal instrument (23) essentially against its direction of outflow out of container (10) into a discharge area of the removal instrument (23) out of which bulk material is sectioned off by means of an off-suctioning device (39) that is connected thereto. To support the off-suctioning of the bulk material, air—by means of an air supply device (17, 19, 20′)—is so piped into the bulk material located in container (10) that the bulk material is fluidized.

Abstract: The invention provides a safety system for a small arms projectile in which an initiating device is impacted by a firing member in order to detonate a main explosive charge. The system requires the firing member to be retained in a safe position in relation to the initiating device by at least two independent mechanisms. The firing member is initially supported in a forward position, in which it assists in holding the initiator device in a safe condition, and is caused to move rearwardly, through inertia, when the projectile is fired, destroying one of the retaining mechanisms and allowing the initiator device to adopt a primed position in which it can be activated by the firing member which at this time is retained by the other retaining mechanism which is automatically released when the projectile is in flight.

Abstract: In a process for analyzing the wavefront of a light beam, a diffraction grating with rectangular meshing is placed in a plane perpendicular to the light beam to be analyzed and optically conjugate with the analysis plane. Different emergent beams from the grating interfere to form an image whose deformations are related to the slopes of the wavefront analyzed. The grating multiplies an intensity function, implemented by a two-dimensional intensity grating, which defines a rectangular meshing of sub-pupils transmitting the light from the beam to be analyzed into a plurality of emergent beams disposed in accordance with a rectangular meshing, with a phase function implemented by a two-dimension phase grating which introduces a phase shift between two adjacent emergent beams such that the two emergent beams are in phase opposition.

Abstract: A device for assembling a steering column bracket with a steering gear shaft, comprising a clamping bolt cooperating with a clamping nut disposed in one of two branches of the bracket, the clamping nut being held in place against rotation and translation by an antirotation elastic member and having a radial protrusion. An axial prepositioning abutment is fastened to the bracket. When the radial protrusion of the clamping nut is pressed against the axial prepositioning abutment, the clamping nut is partly withdrawn along its axis to allow the bracket to be engaged over the end of the shaft. At the end of tightening the clamping bolt in the clamping nut, the clamping bolt neutralizes the antirotation function of the antirotation elastic member in order to allow the clamping nut to escape from the axial prepositioning abutment and immobilize the bracket on the shaft.
