摘要:
A carrier (2) of an apparatus (1) is pivotably mounted on a shaft (6) and can be moved by means of a stepper motor (34) via a cable (40). Apparatus (1) is positioned above tray surface (29) of storage container (28) and has a motor-driven impeller (27) and motor-driven separating fingers (25, 26). Driving motors (7 and 13, respectively) and their appropriate drawing means (12 and 20, 24 respectively) for impeller (27) and for separating fingers (25, 26) respectively are arranged on carrier (2). The sheets are individually arranged on top of one another to form a stack on tray surface (29) and are aligned by impeller (27) on front stopping edge (41), while separating fingers (25, 26) serve to temporarily retain subsequently arriving sheets as long as the finished stack of sheets still lies on tray surface (29). Apparatus (1) is guided via a device for measuring the height of the stack of sheets into a position with respect to the upper side of the stack such that impeller (27) and separating fingers (25, 26) are always correctly positioned for operation with respect to the upper side of the stack whatever the height of the stack. The apparatus can also be moved by stepper motor (24) into raised positions regardless of the height of the stack of sheets.

摘要:
An actuator is provided with a housing to hold a drive system, a transmission which converts its motion into an essentially translational movement of an output element, and an electronic subassembly. The housing has a first housing part which contains the transmission and a second housing part which supports the electronic subassembly, which is detachable from the transmission. The two housing parts, when connected to one another, and without any partitions separating them, form a compartment in which the transmission and the electronic subassembly are contained as enclosed components which are three-dimensionally engaged with one another, but are functionally separate from one another.

Each end of a lifting hose (10) is sealed pressure-tight by means of two clamping strips (12, 14) , one strip (12) having a row of projecting pegs (20) , and the other strip (14) having holes (30) in a corresponding arrangement. The pegs (20) have thickened heads (24), and the holes (30) are stepped, thus giving rise to annular supporting surfaces into which the heads (24) latch in the clamped position of the two flatly folded layers (40, 42) of the hose (10).

摘要:
A back rest (10) capable of being mounted on a lift platform of a lifting apparatus has a foot part (12) and, thereon, a slab (14) pivotable about a swivel axle (34), the slab (14) forming the back part. At the rear, there is a transverse supporting wall (44) moulded or attached to the slab (14) and spaced sufficiently apart from the swivel axle (34). Between the supporting wall (44) and the bottom (24) of the foot part (12), there is a transverse piece of hose (16) disposed parallel to the swivel axle (34) and closed at its ends, which is connected to the hydraulic-water system of the lifting apparatus via a manual control valve. When the piece of hose (16) is filled, the slab (14) is raised to an upright position even if the upper part of the user's body is applying a load to the slab (14). When hydraulic water is emptied out in a controlled way, the slab (14) can be adjusted in an infinitely variable manner, passing through various angles of inclination and reaching a position with a flatter angle of inclination, in which an attachment at the rear of the slab (14) comes to rest on the foot part (12).
摘要:
A transport device has a transport container which is movable over the ground and on which a push-or-pull bar and wheels can be fastened, the transport contained having, in operating condition, two bottom surfaces which are inclined at an angle to each other and extend transversely to a vertical longitudinal central plane lying in the direction of movement and are connected to each other at their lower end by a connecting surface, the transport container being formed by two substantially identical half shells. The half-shells (1, 2) are pivotally connected to each other in the region of the connecting surface (1b, 2b) via a shaft (10a) which extends perpendicular to the longitudinal center plane and they are movable between a position swung against each other and the swung-apart operating position. In the operating position, the half-shells form a hollow space which is open on top and into which a valise-like container (50) having an outer shape adapted to the shape of the hollow space can be inserted
