Abstract: Elastomeric rubber bearing for being connected between two bodies. The bearing employs an element having a series of resilient elements connected together by a series of interposed rigid elements. The thickness of the resilient elements and the width of the cross-section of the resilient and rigid elements vary in relation to the position of the elements.

Abstract: A flexible transmission device for continuously variable transmissions comprises an endless flexible connecting element and a plurality of transverse links. Each link includes at least one groove into which is engaged the flexible connecting element. The links are, preferably, covered by a fabric, and the exterior surface of the fabric is for being positioned in contact with the flanges of the pulleys over which the belt is positioned and operates.

Abstract: A MacPherson Strut assembly, or the like, with a hydroelastic suspension attachment in which the attachment is formed by two thick membranes of elastomeric composition which enclose a liquid. This unit forms a hydroelastic cartridge in which a sliding flap, provided with sealing joints, can move within a rigid confinement cup. The flap itself is encircled by a liquid passage having a large cross section clearance which causes a high level damping of vibrations which result from the resonant movement between masses between which the suspension attachment is mounted.

Abstract: A windshield washer fluid heater, on the engine cooling circuit of an automobile, with an exchange coil 7 around a rigid internal tube 1 which connects the flexible hoses 2 and 3. The exchanger coil 7 is embedded in the polymer material constituting the external envelope element 6 of the flexible hoses 2 and 3. Application to the windshield washing devices of automotive vehicles.

Abstract: A kit for constructing an expansion joint for pipes includes a flexible sleeve and at least one flange, the sleeve for being anchored to the flange by a reinforcement bead of the sleeve which reinforcement head includes an articulated chain of interconnecting elements disposed within the bead, the interconnecting elements being rotatable about one another on an axis of rotation which is substantially parallel to the longitudinal axis of the flexible sleeve.

Abstract: A train of railroad cars having an articulated connection between adjacent railway cars which share a common truck. The articulated connection employs a connecting element having a series of truncated conical resilient elements connected together by a series of interposed truncated conical rigid elements. The thickness of the resilient elements and the width of the cross-section of the resilient and rigid elements vary in relation to the position of the elements.

Abstract: Elastic bushing with hydraulic damping of radial elasticity by circulation of liquid between two chambers opposite one another connected by a very long annular passage located in the round exterior fastening armature. A rigidity decoupling, over a short stroke, is provided by the deformation of a thin wall in each chamber. One side of the thin wall has air thereagainst and the other side has a damping liquid thereagainst. On the air side of the thin wall, movement is limited by an internal fastening ring, and on the liquid damping side by contact with a comb integrated in said internal fastening ring. Application of the bushing is in the fields of mountings for an automobile engine and similar uses.

Abstract: Elastically deformable self-supporting membrane making possible intercommunication between consecutive railway vehicles formed by corrugations of increasing depths and essentially constant thickness. The thickness of each end corrugation is increased and the outer peaks of the corrugations are reinforced by an extra thickness having a higher modulus than the rest of the coating.

Abstract: Forming process, during vulcanization on a mandrel, of the end portions of rubber tubes, using a tool having a radially deformable skirt in the form of a corolla, made of vulcanized rubber which encloses the end portions of rubber tubes using solely the action of the circumferential elasticity of its corolla. The disengagement of the part after vulcanization is accomplished by a simple axial thrust on the corolla. An upturned position of the radially deformable skirt makes possible the installation of the rubber tubes and other preparation operations.

Abstract: An internal combustion engine including a belt tension adjusting device and a belt tensioner damping arrangement.

Abstract: A resilient swivel joint for railway cars and the like. The joint has a first connector and a second connector attached to one another by a resilient member. The joint includes a stop that rotates with the second connector to facilitate relative rotational movement between the first and second connectors and limit relative linear movement between the first and second connectors.

Abstract: Fitted coupling device, formed by two components, for connection to a flexible tube, having a female component and a male component on which said flexible tube is attached by thermal contraction of an external ring. The coupling device has an elastomer O-ring which is gradually compressed between two facing surfaces, one of which is essentially cylindrical and the other of which is a small-angle cone. The compression takes place during an axial manoeuver causing the rolling without sliding of said O-ring, which executes one or more complete turns on itself.

Abstract: An internal combustion engine which includes an apparatus for wrapping a belt more than 180 degrees around a wheel of the engine.

Abstract: Elastic support having deformable ball and socket joints for fastening a trim piece between two mobile elements, permitting the trim piece to remain in a median position, which includes two ball and socket joints exhibiting an elastic recall due to the adherized (or vulcanized) rubber-metal bond, the external rings being permanently fitted into a common assembly tube, the internal rings, in the shape of ball and socket joints, being permanently connected by fasteners in a plane in which the principal relative back-and-forth movements take place, and coming into contact with a thrust washer, by an axial thrust allowing a damping friction effect upon back-and-forth movements.
