Patent DE-4134589-A1 (DE)
Inventor: NICKOL JOHANNES DR ING
IPC: F15B5/00
Filed: 1991-10-19
Abstract: A method of detecting wear in moving mechanical parts is described in which a gas with a predetermined pressure PA is blown against the surface of a moving mechanical part at a predetermined distance s. The backflow of gas brought about at the surface of the mechanical part by the dynamic effect is sensed and the dynamic pressure PR arising in the process is measured. The dynamic pressure PR is compared with the pressure PA with due allowance for the distance s. The change in the dynamic pressure is a measure of the wear. The apparatus comprises at least one nozzle (1) arranged at a distance from the surface of the mechanical part (7) and having a gas-discharge passage (2) which is fed by a gas which is under a predetermined pressure PA. This nozzle (1) has a gas-inlet passage (3) for sensing the dynamic pressure, which is intensified in a pressure intensifier (5) and is measured in a pressure-measuring device (11). The intensified dynamic pressure PY is compared with the predetermined pressure PA in an analysing unit (12). <IMAGE>

Patent DE-4241414-A1 (DE)
Inventor: METTEN JOSEF
IPC: E01C11/22
Filed: 1992-12-09
Abstract: In the case of perforated drainage concrete blocks, in particular paving blocks of various shapes and sizes, which are laid on rain-exposed surfaces, such as roads, paths, squares, carparks and tree-surrounding beds, and are filled at the lateral ends by means of pointing compounds or sand, the problem exists that the holes become blocked during the pointing or introduction of sand. To avoid this, the holes are closed at their upper end until the pointing or sand-introducing operation is complete. Advantageously, this is effected by a filling medium which can be washed away or dissolved by adding water. <IMAGE>

Abstract: In the case of an electronic switching device (10) for a switching magnet (11) whose current flow, in the steady state, can be connected to a supply current source having a low output voltage and, during switching on - for the purpose of rapid excitation - to a capacitor (12) which is charged to a higher voltage level, a charge control stage (25) is provided which automatically initiates further charging cycles of the capacitor (12) after a steady-state current flow phase in the electromagnet has elapsed and a minimum time interval (TA) has subsequently elapsed during which initial recharging of the capacitor (12) takes place by the influence of self inductance, as long as the actual value of the capacitor voltage is less than a desired value (US) which, for its part, is higher than the output voltage of the supply current source. The maximum duration (tp) of such recharging cycles, which take place by briefly passing current through the field winding (11) and subsequently turning it off again, is less than the time interval within which the magnetic field which builds up reaches the attraction field strength of the magnet. <IMAGE>
