Abstract: A mop wringer for a device for cleaning wet floors has a fixed squeezing plate which is positioned between wringer sidewalls. A movable squeezing plate is pivoted to the sidewalls. An actuating lever is configured as a two-armed lever with a shorter lever arm and a longer arm. The actuating lever is connected to the movable squeezing plate by the shorter lever arm and a push guide. A pressing action is carried out by pivoting the actuating lever away from the movable squeezing plate. In the final pressing position, the push guide forms an almost extended toggle lever joint with the shorter lever arm.

Patent DE-19948308-C2 (DE)
Inventor: RUWISCH DIETMAR
IPC: G10L21/02
Filed: 1999-10-06
Granted: 2002-05-08
Abstract: The method involves using a multi-layer self-organising neural network with feedback. A minima detection layer, a reaction layer, a diffusion layer and an integration layer define a filter function (F(f,T)) for noise filtering. The filter function is used to convert a spectrum B(f,T) free of noise, into a noise-free speech signal (y(t)) by inverse Fourier transformation. The signal delay caused by processing the signal is so short that the filter can operate in real-time for telecommunication. All neurons are supplied with an externally set parameter K, the size of which defines the degree of noise suppression of the whole filter. An Independent claim is included for an apparatus for noise suppression during speech transmission.

Abstract: FIELD: hydraulic distributing systems, for example of machine tools, cranes. SUBSTANCE: hydraulic distributor includes proportional electrohydraulic distributor of control circuit 1, main slide valve 2, centering spring 3, pickup 4 for detecting position of main slide valve, working branches 12,13; main lines 14,15 for supplying and draining respectively; additional slide valve 5. When main slide valve is in operational position, draining working branch is joined with draining main line 15 through intermediate cavity of slide valve 5 whose ends are subjected to action of control pressure at one side and at other side - to pressure of cavity 16 arranged just before regulating edge 8 of main slide valve 2. In the result slide valve 5 slightly opens opening 10 by action of pressure in draining working branch until pressure in cavity 16 achieves pressure value in control cavity 6. Therefore, area of opening of regulating edge 8 and pressure drop onto it are determined only by movement of main slide valve 2. Flowrate of working liquid through hydraulic distributor depends only upon value of control signal which at predetermined characteristics of spring sets control pressure and pressure drop on regulating edge 8. When delivery of pump is insufficient, pressure in cavity 16 is less than control pressure in cavity 6; slide valve 5 moves to stopper by pressure action for mutually connecting cavities 6 and 16. Liquid discharge out of cavity 6 causes increased difference between control signal and signal of pickup 4 detecting position of main slide valve. It is possible to use such increased pressure difference signal for controlling delivery of pump. EFFECT: enhanced reliability of hydraulic distributor. 2 cl,1 dwg
