Abstract: The present invention relates to a rubber composition which can be used to form a sealing strip, a process for the preparation of this composition and such a sealing strip. The composition according to the invention, which can be used to form, in the crosslinked state, a sealing strip exhibiting a non-tacky surface and a reduced compression set, is based on at least one elastomer and comprises a crosslinking system comprising at least one organic peroxide. According to the invention, this composition comprises: (pce: parts by weight per 100 parts of elastomer(s)) at least one first organic salt of at least one transition metal chosen from the group consisting of manganese, iron, cerium and vanandium, according to an amount equal to or greater than 2 pce, and at least one second organic salt of at least one other metal chosen from the group consisting of zinc, zirconium, lithium, calcium and barium, according to an amount equal to or greater than 2 pce.

Abstract: An elastomer composition for curing by organic peroxides, the composition comprising an EPDM, a filler such as carbon black, and an additive such as zinc methacrylate, together with an elastomer grafted with maleic anhydride that reacts with the zinc methacrylate to reinforce the curing of the elastomer. The invention applies in particular to the manufacture of power transmission belts.

Abstract: A ring for fitting to a resilient support containing two metal cores interconnected by a piece of elastomer, the ring serving to limit the extent to which the cores can be moved apart accidentally. The ring is rectangular in section and is made up of a succession of alternating layers respectively constituted by tapes of elastically deformable material and by sheets of parallel threads that are strong in traction.

Abstract: A tensioner for a power transmission belt is disclosed comprising a return spring associated mechanically with a tensioner roller with which the belt cooperates for controlling the movement of said roller under the action of said spring, wherein the vibrations likely to arise in the belt are damped by a rubber sheath integral with said spring for forming a chamber closed at its ends by seals, one at least of which has a nozzle for the inlet and/or outlet of air into and/or out of the chamber defined by said sheath and said seals.

Abstract: A device for tensioning a power transmission belt which passes over a pulley. The pulley is supported by an arm and by a rotary part which has one end of an elastically-deformable element fixed thereto, the element being wound around the part and having its other end fixed to a fixed point. The element is constituted by a length of flat belt comprising a layer of cord embedded in a strip of elastomer material. The invention is particularly applicable to the car industry and to the domestic appliance industry.

Abstract: The invention relates to a power transmission belt having a circumferentially ribbed inner surface. According to the invention, the sides (42) of each rib (38) join a small base (40) of the rib via respective convex curved surfaces (44), and the small base (40) of each rib is itself constituted by a concave curved surface. The invention is particularly applicable to transmission belts used in the automobile industry and in household electrical appliances.

Abstract: In an endless power transmission belt including a matrix made from an elastomer material, advantageously of the rubber type, and a longitudinal reinforcement of twisted cords, the reinforcement is chosen, with respect to its physical tension characteristics and its positioning in the matrix, so that the belt has an overall extension modulus sufficiently low so that it makes it possible to fit the belt, by exerting a tractive force, on the pulleys with which it cooperates and yet keeps a minimum appropriate tension after positioning so as to ensure satisfactory operation of the transmission which it equips.

Abstract: A mechanism for transforming a reciprocating rectilinear motion into an intermittent rotary motion comprises a first element having a longitudinal axis and being reciprocable in a direction parallel to said axis, and a second element coaxially surrounding the first element and being rotatable about the axis. The first element carries a set of two cams circumferentially and axially spaced from each other, each cam having, in plan view, the shape of a rectangular part having two opposite sides extending parallel to the axis and a triangular part having a base adjoining the rectangular part, the triangular part projecting from the rectangular part in the direction of the axis, and the triangular parts of the cams pointing in opposite directions.

Abstract: The manufacture of a cylinder, particularly for use in sugar mills, which has an exterior surface defining circular grooves of a cross section having the shape of a triangle, each triangle having an apex at a bottom of the groove in a respective transverse plane extending substantially perpendicularly to the axis of the cylinder, and the bottom of each groove being in communication with longitudinal channels extending substantially parallel to the axis in the cylinder, is simplified by inserting plugs into radial channels in the cylinder in a plurality of the transverse planes before making the circular grooves which are cut into the plugs into the inner ends of which are formed circular slots of sufficient length to connect the grooves to the longitudinal channels.

Abstract: One end of the mobile jaw of a jaw crusher is supported on the crusher frame by an eccentric shaft and a connecting rod supports the other mobile jaw end on a crossbeam pivotally mounted on the frame. The crossbeam has a rear extension accessible from outside the frame and a control wedge is positioned on a bracket affixed to the frame between the bracket and the crossbeam extension. A safety system acts on the crossbeam extension for preventing pivoting thereof when the force applied by the mobile jaw to the crossbeam remains below a predetermined value, the safety system pressing the crossbeam extension against the control wedge.

Abstract: A sugar cane mill facility for the extraction with imbibition of sugar from sugar cane.This mill is characterized by the fact that it includes a fourth roller placed in front of the upper roller, against which it presses and, above the inlet roller and mounted on a mobile support, means acting upon the said support in order to flexibly push the fourth roller towards the upper roller, adjustable stops hindering these two rollers from coming together, and a trash plate placed between the fourth roller and the inlet roller integral with the said mobile support. The juices extracted by pressure between the upper roller and the fourth roller can be recycled to the bagasse layer feeding the mill, either with the juices which have passed through this layer, or with the juices extracted by pressure between the upper roller and the inlet and outlet rollers.

Abstract: In a jaw crusher, pneumatically assisted systems for maintaining the jaw-plate of the crusher on its carrier and for setting the position of the carrier and the jaw-plate mounted thereon.

Abstract: A sugar cane mill comprises two lower cylinders mounted on respective support beds and an upper cylinder carried by two bearing connected to respective cover members pivotally mounted on a respective support bed. Elastically deformable blocks connect each bearing to a respective cover member to permit movements of the upper cylinder with respect to the cover members in a direction approximately perpendicular to a plane defined by the axis of the upper cylinder and the resultant of the pressure forces during normal operation of the mill. The blocks extend on either side of the plane.
