A hydraulic turbine or pump without entry or exit guide vanes supported by a cantilevered stationary tube having a pair of concentric counterrotating first and second shafts with an exit section inclined at an angle relative to the axis of the shafts. A first runner is mounted to the first shaft, including at least a pair of radially extending first blades. A second runner is mounted to the second...

The system has cast iron drains which are fitted with a ring mounting (12). On top of the ring mounting a specially shaped adaptor ring (11) is placed. A water trap (10) prevents the flow of air or liquid effluent from the sewage system into the house, even when the water has evaporated from the trap.

A modulator (3) is incorporated for modulating the direction (theta) of the light beam (2') in the polarisation plane. A polarisation filter (5) converts the variations in the direction of the polarisation plane to an intensity variation in the light beam (2'') which is detected with the aid of a light-sensitive detector (6). The measurement object (7) is firmly connected with the polarisation fil...

A non-resiliently mounted wheel is able to pass over large obstacles (1) more easily thanks to a slide rail (7) that is rigidly mounted on the wheel axle (4). The rail is mounted to allow for a maximum obstacle height and its shape allows the wheel to be lifted up and down over the obstacle in a shock-free manner.
