A valve comprises a kinematic chain having a rotary driving member, a rotary driven member, and an intermediate member. The driving member has a driving contact element in flat or linear abutment on a complementary driving contact element of the intermediate member. The driven member has a driven contact element in flat or linear abutment on a complementary driven contact element of the intermediate member. The complementary driving contact element and the complementary driven contact element () together form an angle between 45&#xb0; and 135&#xb0;. A driving elastic member urges the driving contact element against the complementary driving contact element. A driven elastic member urges the driven contact element against the complementary driven contact element.

The invention concerns a hold-down fastener including a barrel including internal lips cooperating with a screw thread, the lips being directed inwards of the barrel and inclined in a direction of insertion of the screw into the barrel. Each lip includes at least two parts, a first part connected to the barrel and inclined at a first angle relative to the barrel, on the side for inserting the screw, and a second part connected to the first part and inclined at a second angle relative to the barrel, on the side for inserting the screw. The second angle is larger than the first angle and less than 180&deg; to facilitate the insertion of the screw into the barrel, while maintaining the fastener screw-holding power after the screw has been inserted. The invention is useful for fixing in place electric cables, piping systems, and other cylindrical articles.

Hold-down fastener in particular for cables, piping systems or the like

The invention concerns a heat sealing composition including an adhesive framework and a framework forming constituent, the adhesive constituent being a maleic vinyl-anhydride ethylene-acetate polymer or a vinyl ethylene-acetate polymer modified to have epoxy functions and the framework forming constituent being selected from among a block polyether amide, modified or not, and a block polyether ester. The composition is useful for making closure plugs.

The invention relates to an obturating stopper plug as well as to a method of manufacture of this stopper plug. The stopper plug for obturating any opening (2) and comprising a bead of heat-fusible adhesive (7) deposited upon the said stopper plug is characterized in that the bead of heat-fusible adhesive (7) comprises:

Plug for closing any opening and method of manufacturing this plug

An automatic fastening or closing device operating by moving past a dead point and comprising a base portion to which are pivotally connected arcuate tongues themselves pivotally connected by hinges to lugs and comprising each one an outwards projecting portion to form a bearing point allowing the lugs to assume a position remote from each other, i.e. an open locking position, the device being applicable to the fastening and to the locking in blind relationship of a box-like or channel-shaped part onto any support or member whatsoever.

Automatic fastening or closing device operating by passing through a

An attachment fitting for the fastening of a part provided with a rod onto a wall, the attachment fitting having the shape of a shank of plastics material comprising a base forming a cup for receiving a washer with claws whereas above the base are provided elastically deformable tongues allowing to clip the shank into the aperture of a wall while positively retaining the washer within the cup of the base, the attachment fitting being applicable in particular to the fastening of a shield onto a metal sheet belonging to the body of an automotive vehicle.
