In one aspect, a track for use with at least one of a magnetic levitation vehicle and a rolling vehicle having one or more wheels is disclosed. The track includes a first head having a maximum lateral dimension, a second head having a maximum lateral dimension, and a connection portion extending between the first head and the second head. The first connection portion may have a maximum lateral dimension that is less than the maximum lateral dimension of the first head. The track may also include a base and a support extending between the second head and the base.

Abstract: A portable, folding camera dolly track is assembled from a number of folding track sections, each track section having a parallel pair of rails, each rail having a base and a cylindrical wheel-supporting rail element, and a transverse spacer. A continuous, removable, resilient cap is provided on each wheel-supporting rail element to provide a smooth ride over joints formed by adjoining rail elements.

Abstract: In a system comprising at least two conductor rails, in particular composite sections each featuring a rail-shaped load-bearing section and at least one strip-shaped section of another metal of greater wear resistance joined to the matrix of the load-bearing section, the ends of pairs of neighbouring rails are connected electrically by at least one conductor of variable length. The ends of the conductor rails are bent out of the central axis (M) of the conductor rail and led parallel to and a distance (n) displaced from that axis, such that the strip-shaped section of one conductor rail end is approximately aligned with the strip-shaped section of the other conductor rail away from the rail end; the conductor rail ends are joined in such a manner that they can move with respect to each other along the axial direction.

Abstract: The invention concerns a longitudinal transfer system made out of rail sections for guiding transport cars from one processing station to another, two adjacent rail sections being connected with one another mechanically and electrically. A connecting part and section strips are connected with one rail section incapable of sliding and with the other rail section with play but only so tightly that motion of the second rail section is possible, in particular as a result of expansion.

Abstract: An extruded aluminum alloy rail for supporting a shaft for a linear guidance system, the rail comprising a vertical body with a longitudinal notch on its upper surface for receiving the shaft along two generatrixes and a pair of symmetrical longitudinal wings at its base for resting on a fixed stand, the wings being configured so that only the smallest possible surface areas of the wing rest on the support supporting the rail which together with bushed ball bearings support shafts for assuring the linear guidance of high precision modules or mobile platens.

Abstract: The composite conductor rail comprises an aluminum base-section (12) and at least one steel strip (12) as power transfer surface for the power collector. The aluminum base-section is connected in a mechanically stable manner and with good electrical contact to at least one small extruded composite section made of a steel strip and an aluminum retaining section which is ductile, exhibits high electrical conductivity and holds the steel strip in place.

Abstract: A conductor rail comprises a main body of aluminium and a stainless steel facing layer which is produced by welding together two longitudinal J-section strips. The welding operation is effected with the strips in contact with the main body and provides an extremely effective interlocking engagement of the facing layer and main body.

Abstract: The present invention relates to an improved sliding rail construction for rowing exercising machine, in which, the sliding rail for rowing exercising machine is formed by combining an upper sliding stripe made of aluminum alloy and a rail base made of ferrous metal together, and which permits the whole sliding rail construction to be more easily connected to the base rods while providing very good sliding ability for the seat pad placed thereon. Thus the present invention is capable of reducing the production cost, simplifying the manufacturing process and improving the quality of the rowing exercising machine.

Abstract: The invention relates to a composite section having a section or part of the rail cross-section made of light metal and also, mounted securely on the same, a section made of a heavy metal which forms a part of the outer surface of the composite section--in particular a composite conductor rail of aluminum or an aluminum alloy and a steel facing or insert joined to it by means of extrusion.

Abstract: According to the invention a railway turnout comprises two wing rails and a point, carried on a frog, which includes a nose, the running surface of which is substantially co-planar with the running surfaces of the rail of the turnout, the wing rails being provided with tread surface inserts inclined upwardly above the plane of the running surfaces, the incline of the wing rails extending longitudinally along the wing rails towards the heels thereof and commencing at a point corresponding to the point of deviation from the gauge line, of the wing rail, the tread surface of the wing rails being shaped, in cross section, from the edge adjacent the gauge line, at an angle corresponding to the shape of the average worn car wheel and the angles of the incline and the slope being dependent on the taper on the wheels and on the angle of deflection of the turnout.

Abstract: A rigid trolley rail having a continuous unified structural body which is formed by continuously laying a plurality of short trolley rail bodies made of aluminum along the track of a travelling body and by mechanically connecting or welding confronting ends of adjacent trolley rail bodies to each other. Each of the plurality of aluminum trolley rail bodies consists of a base part attached to fixed support parts, a protruding middle part formed to protrude from the middle portion of the upper or lower face of the base part approximately into a T-shape; and a pair of protruding clamping strips positioned with the protruding middle part interposed between them. A long single sheet of stainless steel is bent to cover the protruding middle parts of the aligned rail bodies to form the continuous unified structural body and the ends of the two bent sides thereof are fixed in a gripping manner by bending the pair of protruding clamping strips inwardly to clamp the bent sides against the base part.

Abstract: In a third rail system for electric railroads, double T shaped third rails are used, the web of which has an internal longitudinal slot to receive the guide projections of support insulators and for the space saving mounting of electrical and mechanical connecting parts of fixed and/or expansion joints. With this slot design, good heat transfer and at the same time, a large mechanical moment of inertia are obtained.

Abstract: A guide track arrangement for displaceably guiding one or more servicing units at an open-end spinning machine which includes a number of individual spinning units disposed side-by-side. The guide track arrangement includes at least one rail for receiving runners of the one or more servicing units with the at least one rail being fashioned as a supporting profile having attached thereto a guiding profile for guiding the runners of the service unit or units. The guide profile is adjustably secured at the supporting profile at least in a direction of an occurring load on the guide track. A measuring unit is provided which includes a measuring index cooperable with a further index at the spinning units of the spinning machine so as to facilitate adjusting of the guide profile at the supporting profile.

Abstract: A rigid power conductor to be suspended from an overhead structure or ceiling by means of insulators for the supply of electric energy to electric power driven vehicles on rails. The conductor is a conductor wire held between two side-by-side I-beams urged together so as to form a continuous clamp for the wire.The wire has lateral grooves whereas the I-beams define a conforming downwardly opening slot with projections engaging the grooves in the wire.The joints connecting the successive I-beams are longitudinally displaced, and an expansion joint is disclosed which permits relative displacement of the successive lengths of conductor.There is also disclosed an apparatus for the installation of the conductor wire and various devices for interconnecting the I-beams.
