A wiper device () for a liquid or paste applicator (), the wiper device comprising a tubular body () having an axis (X), and a plurality of blades () that extend from the tubular body () and that are arranged around the axis (X), each blade () comprising a proximal end () that is close to the tubular body, a distal end (), and an intermediate portion (), the wiper device being characterized in that the intermediate portion () of each blade is closer to the axis (X) of the tubular body () than are the proximal and distal ends () of said blade (). A liquid or paste applicator unit including such a wiper device.

The device comprises: a casing () having an open end ('); a composition support (), that is movable in the casing between a retracted position and an extended position; and an actuator () that is suitable for being moved so as to cause the support to move. The device further comprises first and second magnetic elements () that are secured to the support and to the casing respectively. When the support is in its retracted position, the magnetic elements generate magnetic forces between them, which magnetic forces are suitable for holding said support in its retracted position. When the actuator is moved, it causes the support to move, moving the magnetic elements apart from each other, thereby reducing the magnetic forces in such a manner as to enable the support to move towards its extended position.

Device for packaging a product, in particular a cosmetic product

A dispenser device for a container containing a product to be dispensed, the device comprising a body for connecting to the container and presenting a chamber that is open at a bottom end of the body and in which a pump is arranged, connected to a top dispenser head. The dispenser device also comprises a driver that is suitable for being moved so as to cause the dispenser head to move between a storage position in which the dispenser head is substantially retracted inside the body, and a dispensing position in which the dispenser head projects beyond a top end of the body. The dispenser device further comprises a sealing diaphragm that defines a top end of the chamber and that presents a movable end that is connected to the pump, and a stationary end that is suitable for being connected to the container.

A packaging device for packaging a fluid refill, in particular for a cosmetic, the packaging device including a sheath having an open end, and a removable assembly that is suitable for being fastened in removable manner to the open end between a locked position in which the refill is held in the sheath, and an unlocked position in which the refill may be removed from the sheath. The removable assembly includes a retainer interface that co-operates with the open end and that presents an anchor member, and also an actuator member that co-operates with the retainer interface while being suitable for being moved axially relative thereto, so as to be taken into an actuated position in which the actuator member urges the anchor member to be anchored to the open end of the sheath, and a disengaged position in which it releases the anchor member.

The device comprises: a casing () having an open end ('); a composition support () that is movable in the casing between a retracted position and an extended position; and a control piece () that is suitable for being moved so as to cause the support to move. The device further comprises first and second magnetic elements () that are secured to the support () and to the control piece () respectively. When the piece is in its first position and when the support is in its retracted position, the magnetic forces between these elements hold the support. When the control piece is moved, the magnetic forces are reduced and enable the support to move towards its extended position.

The present invention provides phased arrays using monolithic technology of diffusions over whole wafers for working in millimetric wave frequency bands. The reflector array includes a plurality of metallizations connected together by diodes whose capacity can be varied. Thus direct control of reactive impedances is obtained. With the metallized strips placed at a distance substantially equal to .lambda./4 from a ground plane, it is possible to control locally the phase of the reflected signal.

The main object of the invention is an array of optically-controlled elements for the diffusion of electromagnetic energy. The invention pertains to an array capable of diffracting the electromagnetic energy which illuminates it, certain elements of the said array being capable of modulation. The device according to the invention comprises photodetectors which can be used for the optical modulation of the emitting/reflecting elements, whether diffusing or diffracting. The optical modulation provides for the individual control of each radiating element up to very high frequencies. Furthermore, the device according to the invention can be used to reduce the complexity of an array by doing away with the control wiring. The invention can be applied chiefly to the making of radar-testing devices, for example the simulation of bright points, the ultra-high-frequency tomography of the human body and the making of beacons.

The present invention relates to a conical scanning process in a radar antenna. The antenna comprises a principal parabolic reflector (1) and a primary rear-feed source (2) fed by a circular waveguide (3) and displaced with respect to the focus of the parabolic reflector (1). The conical scanning is produced by the rotary movement of the parabolic reflector (1) about the source (2), the said source (2) and the circular guide (3) remaining fixed. The present invention is applicable to tracking radars operating in the millimeter waveband.

The system according to the invention utilizes a transmission--reception radar antenna protected by a radome and an interrogation antenna having at least one set of two networks engaged laterally on the outer wall of the radome. The networks are arranged symmetrically to an axis of revolution of the radome. Supply means supply the interrogation antenna with an ultra-high frequency interrogation signal and the switching and phase-displacement means and the networks constitute an electronic scanning antenna.

The invention relates to a printed monopulse primary source for a radar antenna. The primary source has, arranged on a first face of a dielectric material substrate, radiating zones forming independent site and bearing difference and sum channels. A receiving supply circuit for the radiating zones is arranged on a second face of the substrate, opposite to the first face. Connecting means ensure the electrical connection of the radiating zones to the receiving supply circuit in the thickness of the substrate. Application to airport radar systems.
