Abstract: A locking device on two bodies movable in a sliding manner relative to each other on a sliding track has a locking pin (7) which is guided in a straight-line mechanism in the guide body transversely with respect to the sliding track and is movable in the expelling direction. A socket spanner is guided in a sliding manner parallel to the sliding direction in the guide body. The locking pin (7) projects with an actuating end into a pocket of the socket spanner. The pocket has edges and surfaces for expelling and inserting the locking bolt and for blocking the straight-line mechanism. The locking device is suitable in particular for the connection and aligning movement of two guide bodies as occur in particular in a point operating mechanism.

Abstract: Repairing of tubeless tires and tubeless covers includes injecting a suitable cement through the puncture hole onto the inner surface of the tire, this injection taking place in two successive steps. A first step involves depositing an annular patch of cement around the hole, and in a second step a pearl of cement is deposited concentrically to the hole. The pearl spreads on the annular patch to form a relatively wide deposit centered on the puncture hole and having a thickness sufficient to constitute, after drying and setting, a real repair patch centered on the puncture.

Abstract: A non-vulcanized tire body in the form of an endless band has opposite edges, an inner surface, and an outer surface having a tread. Either a completely enclosed toroidal shaped inner tube formed of non-vulcanized material or a layer of non-vulcanized material having a high impermeability to air is positioned on the inner surface of the tire body. The tire body is then wrapped around the inner tube, and the opposite edges of the tire body are joined to form a completely enclosed tire. The edges may be abutted or overlapped. Thereafter, the tire is vulcanized to form a completely and irremovably enclosed tubular tire.

Abstract: A bicycle tire, notably tubular tire, includes a flexible reinforcing structure added to the tread, the reinforcing structure consisting of high tensile strength yarns assembled beforehand in the form of a knitted sheath or tubular member, and intimately bonded to the rubber by causing the rubber to penetrate into the open meshes of the reinforcing structure during the tire vulcanization.

Abstract: A method of manufacturing tubular tires for bicycles and motorcycles, includes the steps of:laying bead steel wires longitudinally on a first or inner sheet of a tire casing and adjacent the edges thereof;folding the longitudinal marginal portions of the first or inner sheet of the casing around the bead wires in order to cover the wires completely;laying a second or intermediate sheet on top of the first or inner sheet, the longitudinal edges of the second sheet projecting well beyond the in-turned longitudinal edges of the first sheet;laying a casing tread on the thus superposed sheets;shaping the tire assembly thus obtained by imparting a horseshoe configuration thereto, as seen in cross-section;introducing an uncured inner air tube into the casing;closing the tire by assembling by welding the side edges of the second or intermediate sheet projecting from the casing; andvulcanizing the assembly.
