Abstract: A device for preventing the self-unscrewing of a screw cap from a container, e.g. a bottle for use in pharmacy or perfumery and typically containing a volatile liquid product. The container has a neck having formed thereon a screwthread and a projection at or below the lower end of the neck screwthread. The cap screwthread has such a length that, during screwing of the cap onto the neck, the front or lower end of the cap screwthread strikes against the projection when the inside surface of the top portion of the cap is in contact with the top end of th neck. Final screw tightening of the cap causes the front or lower end of the cap screwthread to ride over the projection so that the cap is held more securely in a tightened condition on the container neck.

Abstract: Industrial water filter comprising a filter housing comprising a sidewall and opposed endwalls, a radial inlet and an axial outlet. A stationary filter is disposed operatively between the inlet and outlet and generally eccentrically relative to the inlet axis so as to produce a sweeping flow pattern along the screen. The interior space between the screen and housing is divided diametrically along an axial plane of the filter housing into two separate channels each of which runs along the screen to a debris recovery zone diametrically opposite the inlet. At the inlet end the interior space is divided by a streamlined flow divider and at the debris recovery end by a separator member which is either a flat plate or a streamlined member. A stiffening web may be joined to the endwalls across an axial plane of the screen. A partition may divide the interior space perpendicularly to the outlet axis into two compartments.

Abstract: Heat insulating material of the syntactic type comprising a filler of hollow glass microballs embedded in a matrix, and fabrication method. The matrix is selected from the family of elastomers such as natural rubber, polychloroprene, styrenebutadiene copolymers (SBR), butadiene-acrylonitrile copolymers (NBR), polynorbornenes, ethylene-propylene-diene monomers (EPDM), butyle rubbers and the like. For the fabrication of the material, hollow glass microballs are incorporated into a matrix in liquid or pulverulent phase, and the microballs and the matrix are mixed together without applying large shearing efforts and finally a cross-linking treatment is operated. The material is usable particularly for insulating underwater pipelines for the transportation of gas or oil from off-shore oil fields or urban heating conduits.

Abstract: The pyrotechnic network which is the subject of the invention comprises a particular number of pyromechanisms (23a to 23c) which are arranged in series and each of which is connected to the next by means of a pyrotechnic transmission chain (21). The assembly of these chains is such that a shockwave arriving in a pyromechanism (23a) by way of a chain (21a) ensures the functioning of this pyromechanism and is propagated in the next chain (21b). Moreover, since the network thus formed forms a closed loop with the priming device (10) the initial shockwave is transmitted simultaneously in both directions, this ensuring a redundancy, without the need to duplicate all the components. The invention is used for the control of pyromechanisms in space vehicles.
