Title: Test arrangement for granulates, especially for granulates made of ceramic powders
Inventor: OBERACKER RAINER DIPL ING
IPC: G01N3/08
Filed: 1988-08-30
Abstract: In a device for the determination of the strength of granulates, especially of granulates made of ceramic powder, a position element (3), especially a piezo translator, is provided, connected rigidly to a bending beam (9). The bending beam (9) can be guided with its free end between a counter bearing (14) and a distance pick-up (15) opposite it and working without contact, and bears on the counter bearing (14) with the granulate (10) applied to its free end. By activating the actuator (3), the bending beam (9) with the granulate (10) can be pressed against the counter bearing (14) and the forces acting on the granulate (10) are measured via the distance pick-up (15) by means of the sagging of the bending beam (9) and the deformation of the granulate (10). With this test device, the force effective on the granulate is measured directly, that is to say directly on the granulate, and specifically independently of the distance measurement, that is to say the deformation of the granulate. <IMAGE>

Title: Float ratchet (water-wave power station)
Inventor: KOCH WILLI
IPC: F03B13/18
Filed: 1988-10-19
Abstract: The invention is an apparatus which is suitable for using wave power for generating electricity or mechanical force. This aim is achieved in that on a ratchet shaft there are mounted ratchets of any desired length, on the lever arm of which floats having a low specific density are fastened to the left of the ratchet shaft (1) of the drawing,  Figure 1 section end view left and right  Figure 2 section top view left and right which floats are pressed upwards by the waves, the ratchet (2) becoming locked on the ratchet shaft (1) and the latter being rotated. If the float (5) drops into a wave trough, the ratchet (2) engages and rotates the ratchet shaft further in the event of renewed rising of a wave. In the ratchets (2) having floats (4) to the right of the ratchet shaft of the drawing Figure 1 and Figure 2, the float (4) has a high specific density in order to obtain a high falling weight. When the float (4), raised by the waves, is lowered, the ratchet engages, and as a result of the high weight of the float (4), the ratchet shaft (1) is rotated. Since any desired number of ratchets (2) having floats (4) and (5) can be mounted on the ratchet shaft (1) and these floats can continuously be kept in motion by the waves, the ratchet shaft (1) rotates continuously and the force transmitted from the ratchets (2) having floats (4) and (5) onto the ratchet shaft (1) can be taken-over from it continuously. <IMAGE>
