Inventor: MAURER WILLI
IPC: F03B17/00
Filed: 1991-12-02
Abstract: A drive mechanism has a vertically upright shaft 1, on which in the lower area a turbine 7 is permanently arranged. A tube 3, which conically widens out upwards, is also permanently arranged on the shaft 1, concentrically enclosing this. In the upper area the tube 3 has an overflow 4. A fixed, annular collecting vessel 14 is located below this overflow 4. From this vessel a liquid 15, especially water, is led downwards by way of fall pipes 13 in such a way that the blades 8 of the turbine 7 are acted upon from beneath by means of this liquid 15. Since the tube 3 has previously been caused to rotate, for example by means of an electric motor, the water, due to the centrifugal force and the conical design of the tube 3, shoots upwards and after passing the overflow 4 collects in the collecting vessel 14. In addition helical baffle plates 9, set at an inclined angle, can be provided inside the tube 3 and nozzles 6 can be provided in the area of the overflow 4 for the generation of additional torques.

Patent DE-4211043-A1 (DE)
Inventor: FEHR WERNER
IPC: A21C3/08
Filed: 1992-04-02
Abstract: A process and device for mechanically producing pretzels allows not only the actual process of forming a loop with a piece of dough (62) but also the supply of dough and the removal of the pretzel blanks to be automatically carried out. In the pretzel looping station (44), a piece of dough (62) having a controlled length and spatial orientation is transferred to a pair of grippers (66) which draw the gripped hank of dough (62) at first into a spatial loop form, by carrying out a continuous, symmetric movement with respect to the plane of symmetry of the pretzel, so that the ends of the piece of dough lie next to the "heart" of the pretzel to be formed. After having stopped, the grippers rotate through 360 DEG  and synchronously move downwards away from each other, by the shortest possible way, until they lie over the set pressing point of the ends of the piece of dough on the central portion. The grippers (66) release there the piece of dough (62) and press the ends of the hank of dough on the central portion of the pretzel by a successivelifting and lowering movement. While the grippers are moved back to the initial position, in order to receive the next piece of dough, the finished pretzel blank is conveyed in a parallel direction to itself by freely falling on an underlying transport device when articulated support wings are quickly folded down.

Patent DE-4219880-A1 (DE)
Inventor: MELCHIOR MARTIN THEODOR
IPC: B28C5/12
Filed: 1992-06-19
Abstract: The invention relates to a process for the continuous production and simultaneous transporting of a pumpable building material (construction material) mixture, such as plaster mortar, containing water and hydraulically bindable solid in a homogeneous mixture. The process is characterised in that solid and water are charged to a mixing chamber, approximately in the central region of its mixing space, with continuous metering of proportional mixture components and are transported using a mixing screw (3) with screw helices (4) circulating around a shaft, in a toroidal material flow, with the build-up of a backpressure. In the process they are mixed, proportional air inclusions emerging from the resulting mixture in the opposite direction to the backpressure gradient and being discharged from the mixing chamber at a point in the mixing space opposite to the transport direction. The process is also characterised in that the material flow of the mixture is transported around a concentric baffle plate (11) at the end of the mixing zone, is charged from circumferential regions of the mixing space into the feed side of a slurry pump (16) and is transported further therein with the build-up of a pump pressure. A device is described. <IMAGE>
