Abstract: A tank installation comprising a tank having at least one flexible wall arranged to rest on a rigid apertured partition, which per se does not form part of the invention. A flexible duct is joined to said wall and is intended to pass through the aperture in the partition. One end of the duct is connected to the flexible wall of the tank by a folded-over portion located inside the tank, and the other end of the duct is arranged for connection to another device that is to be placed in communication with said tank.The other device may be a second tank which also comprises a flexible wall with a flexible duct substantially aligned with said flexible duct of said first tank, and the extremities of said two flexible ducts are joined to a rigid pipe. These two tanks may be adjacent, the flexible duct of said second tank being directed towards the inside of the second tank and the rigid pipe is located within the second tank.

Abstract: A segmented mold for molding tire casings has a fixed lower mold part for molding one side wall of the tire, a series of molding segments for molding the tread movably mounted on the lower mold part to be slidable and swingable along radial planes, an axially movable upper mold part for molding the other side wall of the tire, and means cooperating with the segments to effect the movement thereof along the radial planes. The mold also has elastic members interposed between the fixed lower mold part and the segments for continously urging each of said segments toward an open position in which the segments are radially retracted and swung upward and to the outside of the mold to free a passage for the tire when the upper mold part is lifted off. These members include a first spring for pulling each segment radially outward and a second spring for tilting each segment vertically upward toward an open position.

Abstract: A floating anti-pollution barrier for combating water pollution and method of using the same is disclosed. The floating pockets of the barrier, the openings of which are downwardly disposed, are given their shape and kept in shape by masses of a material which is lighter than water. These masses preferably consist of a cellular material which is watertight and minimally compressible, of inflated bladders, or of air blown into the pockets. In a preferred embodiment in which the pockets are given shape by the masses, air enters the shaped pockets and is trapped therein to effect flotation of the barrier, and provisions are made for accommodating retention of the barrier at the surface of the water, even in the event that water fills the pockets, since the masses then act to effect the flotation of the barrier.

Abstract: A vehicle tire has a radial carcass and a reinforced crown and the tire beads each comprise at least one beadwire surmounted by a filler strip whose cross-section is broadly tapered towards the side-wall and which is made of a rubbery mixture reinforced with short fibres. According to the invention, the fibres reinforcing the filler strip are, at least in part, orientated in the radial direction of the tire so that the mixture used for the strip has a ratio of anisotropy at least equal to 2:1. The filler strip may rise up the side wall to a height of between 0.2 and 0.5 times the cross-sectional height of the tire.

Abstract: This invention relates to flexible hoses having a rubber body and a flange at each end thereof. The rubber body is strengthened by a reinforcement comprising continuous metal elements extending from one flange to the other and whose ohmic resistance from flange to flange needs to be high. The surfaces, of said flanges situated facing the metal elements of the reinforcement are covered with an insulating layer formed from a glass cloth having high mechanical strength and high electrical resistance and from a firm binder of high electrical resistance comprising an epoxy resin, the insulating layer adhering to the metal surfaces of the flanges and to the rubber body of the hose. The layer of glass cloth preferably consists of a plurality of plies which are superimposed and having filaments whose respective axes are at an angle of 45.degree..

Abstract: This invention relates to flexible high-pressure hoses of the kind having a wall made of elastomeric material which is strengthened by a stress-resistant reinforcement which is embedded in the wall and which is formed by at least two superimposed layers of cables inclined in opposite directions, with, at one end, an obturating or connecting device comprising a spigot which is inserted in the hose and an external clamping collar, the spigot and the collar having, on their adjacent surfaces, a channel in the one case and a corresponding ridge in the other.According to the invention, the channel and the ridge each have parallel clamping surfaces which are inclined in opposite directions and their radial height is substantially equal to or slightly greater than the thickness of the wall of the hose so that, in the state where the device is assembled to the hose, the crest of the ridge at least partly enters the channel.

Abstract: The present invention relates to vehicle tires of the kind having a crown belt formed from at least one pair of plies made of cords which are orientated in directions which intersect at small angles, and having sidewalls each reinforced by at least one strong half-ply making up a carcass which is interrupted under the belt.The invention which consists in a combination of the following features:(a) the tire has a low cross-section in which the ratio of height over width is less than 0.8, for example between 0.3 and 0.7, and,(b) the half carcass-plies are connected together in the area of the tire crown of the tire by a layer which has a strength of less than 50 daN per centimeter of width for an extension of 10% and whose elastic extensibility is at least 10%.

Abstract: A pneumatic tire is disclosed having a top belt under the tread, which belt comprises two superimposed plies made of cables having a high modulus of elasticity. The upper ply is narrower than the lower ply. Lateral strips, which are co-extensive with the circumferential length of the plies, are joined to each of the edges of the two plies. Each lateral strip is co-extensive with the ply to which it is joined and constitutes a layer of flexible circumferentially extending cables embedded in rubber and is joined end-to-end on a bias whose angle is the same as that of the respective plies to which they are joined.

Abstract: A pneumatic tire of low cross-section of a height to width ratio equal to or less than 0.8, and which is suitable for use at high speed. The tire has a radial carcass and a crown belt interposed between the radial carcass and the tire tread for the width of the tread surface, the belt being formed from two main plies of unequal width composed of high modulus flexible cords which are orientated in opposite direction at small angles, one at least of the plies having its lateral edges folded over and flattened against the inner face of the belt. A third, narrower, belt ply is positioned on the outer face of the belt against the central part of the ply whose edges are folded. The width of the third ply is between the width of the narrower and unfolded ply and the width of the space between the edges of the wider folded ply.

Abstract: A flexible support for supporting a conveyor belt of a conveyor having a frame. The flexible support includes at least one flexible element extending beneath a portion of the width of the conveyor belt, which flexible element is attached in the region of the ends thereof to the frame of the conveyor. The length of the flexible element is greater than the linear distance between the attached ends of the flexible element and the flexible element delimits support areas for supporting a portion of the width of the conveyor belt extending at least on opposite sides with respect to the longitudinal median plane of the conveyor. The at least opposite side support areas of the flexible element are responsive to the travel of the conveyor belt for being drawn in the travel direction independently of one another.
