The invention relates to a pre-tensioning prestressed composite beam structural system and a construction method of the pre-tensioning prestressed composite beam structural system. Lower longitudinal reinforcements are bound and lapped on lower longitudinal prestress wires in composite frame beam prefabricated components; the lower longitudinal reinforcements are inserted into frame pillars; second pre-buried steel plates are buried in the lower end portions of the composite frame beam prefabricated components; lower portion longitudinal prestress wires are buried in the composite frame beam prefabricated components; secondary beam longitudinal reinforcements are lapped and bound on the lower portion longitudinal prestress wires; the second pre-buried steel plates are welded with the secondary beam longitudinal reinforcements; first pre-buried steel plates opposite to the second pre-buried steel plates are arranged on the composite frame beam prefabricated components; pitch point steel plates are respectively welded on the first pre-buried steel plates and the second pre-buried steel plates; and the pitch point steel plates are connected through bolts, which enables the composite frame beam prefabricated components to connect with composite secondary beam prefabricated components. Wires and longitudinal reinforcements are lapped to use in the pre-tensioning prestressed composite beam structural system, and therefore the connecting mode of the pre-tensioning prestressed composite beam structural system is scientific and reasonable, and quality is safe and reliable.

The present invention relates to an apparatus for coupling an implement to a working vehicle, having two lower link bars, a length-adjustable upper link bar, and two lifting elements. The end closest to the working vehicle, of each of the lower link bars and the upper link bar, is swingably mountable, and the other end closest to the implement is likewise swingably mountable. The upper link bar is essentially disposed centrally in the upper region of the coupling apparatus. The two lower link bars are disposed essentially laterally in the lower region of the coupling apparatus. One end of each of the lifting elements can be swingably mounted on a respective lower link bar. A supported load from the implement which acts on the working vehicle does not lead to diminishment of the load on a vehicle axle. For this purpose, the coupling apparatus is characterized in that the respective other ends of the lifting elements directed toward the implement, can be swingably mounted in essentially an upper region of the coupling apparatus.

The invention relates to a magnetic coupling pump, with the motor-driven part of the magnetic coupling lying radially inward and the radially outward part of the coupling, together with the pump rotor, having a floating fit in the pumped fluid such that the rotating part of the floating bearing is also radially arranged over the outer magnets. The wall of the pump housing can itself be embodied as the stationary part of the floating bearing with the possibility of direct external access (lubrication, sensor mechanism) and an effective convectional cooling. Dry running on operational faults can be avoided by means of the floating bearing arranged far to the outside, as the damaging gas fraction collects in the radial interior of the pump and remaining traces of liquid are continuously driven outwards and thus contribute to bearing lubrication. By means of an additional annular barrier, the loss of residual fluid can be prevented. The disclosed novel floating bearing permits a large volume separating case which itself permits components of the roller bearings of the motor-driven magnetic coupling section so much installation space that the axial installation length of the complete pump can be significantly shortened.

The invention discloses a tube-framework plastic composite tube and a producing process thereof. The structure of the tube-framework plastic tube comprises a tube body, wherein the tube body comprises an inner pressure tube, an entwining structure wall and an outer wrapping layer in sequence from inside to outside; the inner pressure tube is an integrally formed thin-wall tube; the wall of the inner pressure tube is evenly, externally and spirally wound with the entwining structure wall; and the outer wrapping layer evenly wraps the outer sides of the inner pressure tube and the entwining structure wall. Besides, a layer of glue is evenly sprayed to the external surface of the entwining structure wall; and the entwining structure wall is a belt-shaped special-shaped profile or a hollow tubular profile. The tube provided by the invention has the characteristics of high ring stiffness, high inner pressure bearing capability, low cost and high production efficiency.

People who wear a prosthesis currently have to use a bathing prosthesis if they wish to pursue water sports or take a shower or reach a body of water for recreational purposes and take active part in beach pursuits safely. However, these are usually taken off for swimming though this is very often not possible in the case of rocky shores or unsupervised beaches, quite apart from the unwelcome attention to which the person wearing the prosthesis is sometimes exposed in doing so. To solve this problem, a protective device for use for exterior prostheses is suggested, in which the protective device is a protective covering made from an at least semi-elastic, durable and damage resistant material being watertight or custom-designed sufficiently preventing a penetration of water into the inside of the protective covering and being dimensionally conformed to the shape of the body, and at least one end of which is furnished with a cuff or sleeve or collar like semi-elastic device that is dimensionally adapted to the contours of the anatomy of the person wearing the protective covering to prevent water or moisture or foreign bodies from penetrating the protective covering. This is particularly convenient and easy to carry and use when travelling and for recreational sport.

A clamping device comprising: a collar (10) comprising: a belt (12) suitable for being disposed around one or more articles to be clamped, and at least two lugs (14, 16) that are upstanding relative to said belt towards the outside thereof; and a tightening system (18, 19) suitable for co-operating with the two lugs so as to move them closer together; in which device at least one of the two lugs has a connection portion via which it is connected to the belt (26), which connection portion is upstanding relative to said belt, and a tightening wall (30) folded back towards the belt, the tightening system coming into engagement with said tightening wall during tightening of the collar; wherein, on its outside face, the belt (12) has at least one projecting portion (40) situated between the connection portion and the tightening wall, the tightening wall (30) coming into abutment against said projecting portion (40) while the collar is being tightened.
