Abstract: Spherical heat foamable pellets (2) are used for reinforcing honeycomb structures (4). The pellets are preferably of average diameter from 0.5 mm to 0.9 mm and preferably at least 80% of the pellets have a diameter in this range. The pellets can form a free flowing stream which can be poured into the cells (5) of the honeycomb where they can be foamed by heating to form a reinforcing foam which can also bond the honeycomb structure to facing sheets. It is preferred that the pellets are based on a thermosetting resin and contain a curing agent that can cure the foamed resin to produce an integral rigid reinforcing foam within the cells of the honeycomb.

Abstract: A fueling device for fueling the thrusters of a launcher is disclosed. The device includes a ground module and an on-board module. The ground module having at least: a ground pipe; a ground valve; and a ground plate provided with a ground passage, and the on-board module having at least: an on-board pipe; an on-board valve; and an onboard plate provided with an on-board passage. The device also includes a hydraulic coupling system between the onboard module and the ground module enabling fluid communication to be established between the ground passage and the on-board passage. A first annular enclosure is situated between the on-board plate and the ground plate around the hydraulic coupling system that, when connected to suction, enables the on-board plate and the ground plate to be held in a connected-together position.

Abstract: The invention relates to a fueling device for fueling the thrusters of a launcher. In characteristic manner, the device comprises: a ground module (20) comprising at least: a ground pipe (22); a ground valve (21); and a ground plate (26) provided with a ground passage (28); an on-board module (30) comprising at least: an on-board pipe (38); an on-board valve (36); and an on-board plate (32) provided with an on-board passage (34); and a hydraulic coupling system (40) between the on-board module (30) and the ground module (20) enabling fluid communication to be established between the ground passage (28) and the on-board passage (34), and a first annular enclosure (50) situated between the on-board plate (32) and the ground plate (26) around the hydraulic coupling system (40) that, when connected to suction, it enables the on-board plate (32) and the ground plate (26) to be held in a connected-together position.

Abstract: Inserts such as screw threaded receivers are provided with an activatable adhesive so they can be inserted into a cavity of an article of manufacture and the adhesive activated to secure the insert within the article.

Abstract: A process for the repair of a honeycomb structure which comprises a honeycomb bonded to at least one surface layer wherein a replacement for a damaged piece of the structure is bonded to the honeycomb structure by means of a foamable adhesive material.

Abstract: Improved means for joining tubular structures are provided which consist of a plug for insertion into the tubular structure provided with a plurality of attachment points which can be used to link one or more tubes the plug is provided with a rim of greater cross section that the internal cross section of the tubular structure to control the extent to which the plug can enter the structure.

Abstract: A support for a vehicle grab handle comprises a mounting part provided to be fastened to the vehicle, a support part provided to be joined to a grip part, and a support spindle by which the support part is rotatably supported on the mounting part. The support spindle is formed as an integral part of the mounting part and is injection-molded into the support part so as to be rotatable.

Abstract: The redundant regulation valve for controlling fluid flow comprises a valve body defining a passage for the flow of the fluid, a main throttle element movable by means of a main control device to selectively obstruct the passage, and a redundant throttle element movable by means of a redundant control device. When the valve is in its closed position in normal operation, the main element and the redundant element are in contact with each other. In this normal closed position, the main element is close to its fully-extended position in the closure direction and it obstructs only about half of the passage, while the redundant element is in a position of medium extension. The stroke of the redundant element is such that the redundant element can be controlled to obstruct the entire passage even when the main element is in its fully-open position.

Abstract: The present invention relates to an electrically controlled leakproof valve having a fluid feed channel and at least one channel for delivering said fluid, rotary displacement of a distributor plug in said valve being under the control of an actuator. The actuator comprises an axially pierced rotor through which the fluid from the feed channel flows without headloss, the actuator being connected to the valve body in leakproof manner without using dynamic sealing devices. The present leakproof valve is particularly suitable for use in corrosive environments, and in particular under cryogenic conditions.
