Abstract: Installations for trans-loading piece goods in the form of load units (3) such as containers, returnable vessels, semi-trailers or the like between road and railborne vehicles (2) comprise a single or multiple storey store (5, 6) for the load units (3) on one side of a single or multiple track railway line (1), a single or multiple lane roadway (9) on the other side of the store (5, 6) as well as lifting gear means (10, 11) for transferring the load units (3). In order to reduce the required floor area for simplifying the lifting gear means to be employed as well as accelerating the transfer, the store (5, 6) in such an installation is to be divided longitudinally into two parts with an operating space (7) accommodated between the store portions (5, 6) and having fixed to the four comers of the operating space (7) one load lifting gear means (11) each. The width of the operating space (7) corresponds at least to the length of the largest load unit which is to be transferred.

Abstract: Apparatus for the installation for transferring piece goods between road and railborne vehicles includes a receiving and an issuing store, the outer sides of which remote from the railway line adjoin a loading roadway for the unloading or/and loading of road vehicles, each of the stores is provided with a plurality of loading lifting gears adapted to travel longitudinally for transporting load units beyond the railway lines between the roadway and at least the store, a plurality of train transfer lifting devices are provided to travel longitudinally, their operating radii extending laterally beyond the railway line in the direction towards the stores, and additional transport devices are provided which bridge the mutually separated ranges of the lifting gears and the train transfer lifting devices for transporting load units transversely to the railway line.

Abstract: A deployable bridge includes a plurality of identical bridge sections each having two identical track elements. Each track element has a roadway carrier, a bottom boom and adjustment elements connecting the bottom boom with the roadway carrier. The bottom boom of each track element includes a mid section and two end sections flanking the mid section. Each track element further comprises pillars having opposite first and second ends. The first end of the pillars is articulated to the mid section of the bottom boom. Each track element also has a drive shaft assembly suspended from the track element; spindle sleeves inserted on the drive shaft assembly; and a spindle head threadedly mounted on each spindle sleeve. The pillars are articulated by the second end thereof to a respective spindle head.

Abstract: A bridge includes a bridge element which has a basic bridge body; a folding ramp situated at opposite sloped end faces of the bridge body; a hinge connection pivotally attaching each folding ramp to the bridge body; and a locking device supported by the bridge body for locking the folding ramp to the bridge body in the downfolded position of the ramp in which the ramp forms a common access ramp with the respective sloped end face of the bridge body. The locking device includes a locking pin and an actuating device for moving the locking pin into a locking position or into a withdrawn position. In the locking position the locking pin extends into a locking pin-receiving opening of the folding ramp if the folding ramp is in its downfolded position or into a locking pin-receiving opening of an adjoining basic bridge body in the upfolded position of the folding ramp. The hinge connection includes a double-jointed lever connected to the bridge body and the respective folding ramp by pivotal joints.

Abstract: An apparatus including a frame, a cantilever arm movably mounted on the frame, and a servomotor operatively connected to the frame and the cantilever arm for setting a height position of the cantilever arm. The servomotor is exposed to tension loads derived from forces acting on the cantilever arm. The apparatus further includes a device for relieving the servomotor of the tension loads for an arbitrary period. The device includes a tension member attached parallel to the servomotor for the arbitrary period. The device further has an intermediate member having a first pivot joint operatively articulated to the cantilever arm for introducing the tension loads into the intermediate member, a second pivot joint for being coupled to an end of the tension member and a third pivot joint for being releasably coupled to the servomotor. The first, second and third pivot joints are spaced from one another and form the three corners of an imaginary triangle.

Abstract: A belt assembly for an overhead magnetic separator has a belt having an inner face and an opposite outer face and a pair of opposite ends one of which is cut away on the inner face and the other which is cut away on the outer face so that the cut-away portions can normally be lapped against each other to form the belt into an endless loop of substantially uniform thickness. The belt further is formed at the other end on the inner face with a shallow transverse inner groove. Respective flat inner and outer nonmagnetic strips engage the respective faces of the belt at its lapped ends with the inner strip lying in the groove. A plurality of nonmagnetic threaded studs fixed in the inner strip project through the lapped belt ends and through the outer strip and respective nonmagnetic nuts on the studs bear on the outer strip and clamp the lapped belt ends between the strips. A layer of elastomeric material is provided on the inner strip generally level with the inner belt face.

Abstract: A conveyor system includes a back arm pivotal about a first vertical axis; a discharge arm pivotal about a horizontal axis and about the first vertical axis; a discharge belt mounted on the discharge arm and extending rearward, beyond the first vertical axis, to the back arm; and a connecting bridge pivotal about second and third vertical axes, and supported on a separate, movable device so as to be longitudinally displaceable. The connecting bridge is articulated to a component of the conveyor system above the back arm. The second vertical axis is spaced from the first vertical axis at a predetermined distance and disposed diametrally opposite a discharge end of the discharge belt with respect to the first vertical axis. There is further provided a connecting belt mounted on the connecting bridge and feeding the discharge belt.

Abstract: A filter apparatus has a drum rotatable about an axis and having a foraminous outer wall with an inner surface, a support screen lying directly on the inner surface, a filter mesh lying directly on the support screen, and a protective screen lying on the filter mesh and holding same against the support screen. The support screen and mesh are held in place by a retaining seal having at least two lips defining at least one recess snugly receiving the edges of the support screen and mesh with one the lips between the support screen and the drum inner surface. The protective screen lies on the other lip of the seal and presses the seal against the surface of the drum while clamping the edges in the recess.

Abstract: A deployable modular bridge has a central girder; two side girders flanking the central girder; and couplings connecting each side girder to the central girder along the lower zones of the girders parallel to the bridge length. The couplings are arranged symmetrically with respect to a central vertical longitudinal plane of the bridge and permit displacement of the side girders relative to the central girder parallel to the bridge length. Each coupling includes a rail affixed to the central girder and extending parallel to the bridge length. The rail has a guide track formed thereon. Each coupling further includes a roller mounted on a respective side girder and engaging the guide track.
