Title: Controllable hydraulic motor with rotor and stator - has stator nozzles aimed at rotor blades at different distances from axis of rotation
Inventor: SCHACHT HARRY
IPC: B60K7/00
Filed: 1992-02-07
Abstract: The blades on the rotor form radial impact faces (6) for the hydraulic fluid. The nozzles (4) in the stator (2) are aimed at the blades, and are at different distances (11) from the axis of rotation (3). Those at the same distance from the axis can be assembled into a group, and there can be several such groups. The stator can be disc-shaped, with the nozzles at the front and annular chambers (8) at the rear. Each of them supplies a group of nozzles at its radius, and is individually controllable. The rotor can also be disc-shaped, with the blades inclined to the axis of rotation and the nozzles aimed at right angles to the nearest ones. Relatively large ports in the rotor discharge the fluid from the blades. USE/ADVANTAGE - For fork-lift trucks,loaders etc,.with simple design and wide range os speeds,without need for mechanical gearbox.

Abstract: A belt conveyor for bulk material has a conveying path with a horizontal section in a fixed location and a vertical section in a movable location and comprises a base belt (1) in both sections and a cover belt (2) in the vertical section. The base belt is guided away from the conveying path in the region of a transition section between the vertical and horizontal sections so that the conveyed material (3) is discharged from the base belt and moves over a short path following a ballistic curve. Subsequently, the material is guided from the vertical to the horizontal direction, or from the horizontal to the vertical direction, by a redirecting belt (13) arranged in the form of a quadrant of a circle. Thereafter, the material, again following a short path of a ballistic curve, is picked up again by the base belt (1). The cover belt (2) covers the base belt (1) in the vertical section and also the redirecting belt (13) in the transition section. <IMAGE>

Patent DE-4213862-A1 (DE)
Inventor: PALM ERICH
IPC: F16B19/08
Filed: 1992-04-27
Abstract: A blind rivet-type clamping fastener (1) has a deformable sleeve part (2), a drift part (4) and a drilling part (5). The drilling part (5) is held in a movable or removable manner in the axial direction (6), with respect to the free end of the clamping fastener (1). During setting, the free end area (16) of the sleeve part (2) cooperates with radially projecting stop surfaces (12) of the drilling part (5), so that an axial force is exerted on these stop surfaces (12) of the drilling part (5). As setting continues, this force acts on the drilling part (5), displacing or removing it in the axial direction.

Inventor: KAESTINGSCHAEFER GERHARD DIPL
IPC: F27B7/22
Filed: 1992-05-18
Abstract: The invention relates to a rotary drum of relatively large dimensions, the casing of which is mounted rotatably by ball races (3, 4) on in each case a roller pair (7) of a roller station (5, 6). To this end, the rotary drum casing (2) bears only two ball races (3, 4) which are mounted in a rotationally fixed manner and are mounted on two roller stations (5, 6), at least one of which simultaneously forms the rotary drive device for the rotary drum in the form of a friction-wheel drive. The result is thus a combination of features, by means of which the rotary drum is mounted in a statically determined manner and at the same time can be reliably driven in an extremely simple manner.

Title: Tubular, longitudinally changeable supports which can be fitted in clearances of shuttering slabs of cavity floors
Inventor: BACHER MICHAEL
IPC: E04F15/024
Filed: 1993-09-22
Abstract: Tubular, length-changeable supports which can be fitted in clearances of shuttering slabs of cavity floors and can be filled, via the clearances, with screed which is to be applied on to the shuttering slabs are intended, on the one hand, to be stable, in the non-filled state, under footstep loading and, on the other hand, to be capable of compensating for unevennesses in the unfinished floor on to which the shuttering slabs are laid. For this purpose, the downwardly free end of the supports is provided in each case with a centring collar and an axial stop for the correctly fitting plugging-on of a lengthening sleeve or cap. In each case one deformable region may be provided in the support itself or in the plug-on lengthening sleeve. At least one zone of higher elasticity is arranged within the deformable region. This zone of higher elasticity is stretched out in elongate form in the initial state and can be compressed to a predeterminable minimal longitudinal extent. In this compressed state, which determines the desired distance of the shuttering slab from the unfinished floor, the support can be loaded in an essentially deformation-free manner.
