  • Publication number: 20060047050
    Abstract: A sulfur-crosslinkable adhesive composition of the non-aqueous type, that is to say not requiring the presence of water, usable for direct bonding of a pregelled polyester or vinyl ester composite to rubber in the uncured state. The composition comprises polyvinylpyridine-styrene-butadiene elastomer (“p-VSBR”) in combination with a polyester or vinyl ester resin. Preferably, the resin used is a novolak and/or bisphenol based resin of the epoxy vinyl ester type. This composition, unlike conventional RFL adhesives, does not require any activation treatment, such as intermediate drying, at the time of use. A process for preparing such an adhesive composition, use of said composition for the manufacture of laminated composite parts.

  • Publication number: 20060017240
    Abstract: A vehicle having a suspended body (1), at least two wheels (2) each mounted on a wheel support. Each wheel support is mounted on a suspension device (5) comprising a suspension support (4) and means for guiding the wheel support relative to the suspension support. The suspension device allows a vertical displacement of the wheel support relative to the suspension support, the size of the displacement being sufficient to produce the vertical suspension movement required. At least one wheel is arranged transversely on one side of the body and at least one other wheel is arranged on the other side of the body. Each suspension support is connected to the body by a height variation mechanism (3, 7, 11, 12) which allows the relative height of the suspension support relative to the body (1) to be varied. Each height variation mechanism is actuated by height control means (15, 16, 17, 18).

  • Patent number: 6875297
    Abstract: A process for making a composite product in which reinforcement fibers are subjected to a composition based on a thermohardening resin and a photoinitiator appropriate to the irradiation by which the composition is to be treated. The resulting pre-impregnated material is introduced into a prepolymerization device, in which the pre-impregnated material is prepolymerized by appropriate irradiation. Lengths of the precomposite are applied to a support, the shape of which is dictated by the shape of one face of the composite part which is to be made, and are stacked one on another in a suitable number and placed snugly against the shape of the support, and the stack is subjected to final molding at a suitable pressure and temperature in order to polymerize the resin and to join the different lengths of precomposite.

  • Patent number: 6671598
    Abstract: For a vehicle, all of whose road wheels are steerable wheels, the steering instructions are transmitted by electrical means. The vehicle path is altered by a device comprising a component which is similar to a steering wheel, and has two handles 32G, 32D arranged at a certain distance from the rotary shaft and preferably substantially symmetrically with respect to it. The rotary shaft is provided with at least one angle-of-rotation sensor 34 and has a sensor for the tilting force of the handles. The driver turns the handles 32G and 32D clockwise to turn right and anticlockwise to turn left.
