Title: Hydraulic support device
Inventor: RASTETTER ADOLF
IPC: B66C23/80
Filed: 1988-04-02
Abstract: A hydraulic support device, in particular for supporting vehicles with a displaceable bearing rod which is constructed as a piston rod of a working cylinder and with a clamping device which blocks the movement of the piston rod and has a plurality of axially displaceable clamping jaws which can be pressed, by means of a spring element, onto guide paths which are fixed to the housing and located obliquely with respect to the longitudinal axis of the piston rod in order to assume a blocking position at the circumference of the piston rod, and with a cylinder-guided servopiston for displacing the clamping jaws counter to the spring force into the opening position, is to be constructed as a transverse bearing for receiving bearing forces. This takes place according to the invention in that the clamping jaws (5) are constructed so as to be capable of being displaced into the opening position bounded against a stop (10) with axis-parallel advancing movement such that the clamping jaws (5) form a sliding bearing (4, 5) with defined bearing gap for longitudinally guiding the piston rod (4) (Fig.). <IMAGE>

Title: Barn for rearing livestock, in particular calves
Inventor: EGLE FRANZ-XAVER
IPC: A01K1/02
Filed: 1988-06-16
Abstract: The invention proposes a barn for rearing livestock, in particular calves. Up until now, calves have been kept and reared in solid-walled enclosures in livestock buildings. Conventionally, all the calves have been accommodated in one large enclosure, sometimes in large numbers. The known calf barns are high in outlay and require a considerable amount of work. Moreover, there is an increased risk of infection when keeping the animals in large groups. These disadvantages are avoided according to the invention in that the barn is configured as a self-supporting structure which can be drawn by a tractor and rests, in the use position, on slide rails (8) which diverge somewhat from one end side (4) of the structure to the other (2). <IMAGE>
