Title: Noise suppression circuit for TV receiver - uses common mode rejection by blanking low pass filtered input video to give step signal
IPC: H04N7/16
Filed: 1975-05-21
Abstract: The noise suppression circuit for a television receiver suppresses noise close to the carrier, i.e. within a few hundred Hz. The video signal is passed via a low pass filter, to remove the colour burst signal, to a blanking-out switch (5) controlled from the delayed synchronous pulse separator. The blanking-out switch generates a step signal from which a further low pass filter can reconstruct the noise, which can then be subtracted (2) from the original signal (common mode rejection). The high frequency noise is also filtered out (10) and adjustably added to the common mode noise for subtracting from the original signal.

Patent CH-636684-A5 (CH)
Title: Composite profile
Inventor: SCHWEIZER ERNST JAKOB
IPC: E06B3/263
Filed: 1978-12-04
Abstract: The composite profile, especially for window frames or door frames, consists of two parallel metal profiles (1, 2) having insulating clamping holders (3) which are arranged between them and connect the metal profiles (1, 2) to one another such that they cannot be detached. Provided in the metal profiles (1, 2) is in each case one longitudinal groove which is bounded by a pair of ribs (10) and has undercuts (12), which run longitudinally in the ribs (10) and behind which the end parts of the clamping holders (3) engage. The undercuts (12) are constructed in the form of channels and have in each case two inclined walls (13). The end parts are provided with wedge-shaped sections which are bounded by in each case two inclined surfaces (14) which correspond to the inclined walls (13). These sections are pressed into the undercuts (12) in a clamping manner. As a result of this construction, the installation of the composite profile is largely independent of tolerances. The clamping holders are braced only at the ends and can thus be more highly loaded. As a consequence of the end parts fitting into the undercuts like V-belts, the tightening takes place on both sides, the clamping holders are engaged more quickly and are centred better. <IMAGE>

Title: Control system for vortex layer sepn of liquids - - partic of oil from water
IPC: E02B15/04
Filed: 1971-01-29
Granted: 1972-09-15
Abstract: To recover oil floating as a layer on water, a vortex can be created in which the layer thickness is locally increased so that it will take a suction inlet to a pump which can draw off the oil without water. The vortex is automatically controlled by a system employing sensing devices which detect the presence of the oil at three levels. The top and bottom detectors, respectively increase and decrease the vortex speed, and the middle detector regulates the rate at which a separating pump draw off the oil. The control of vortex ensures that water is not drawn into the separating pump and that oil is not emulsified by the vortex-forming rotor.

Title: Electrodialysis desalination appts - for brackish water
IPC: C02F1/46
Filed: 1971-07-09
Granted: 1973-02-23
Abstract: Desalination, or even demineralisation, of brackish water is effected by dialysis in the conventional manner. The dialysis cell is formed by a series of compartments, some arranged on a dilution circuit and the others on a concentration circuit, the circuits being sepd. by semi-permeable membranes. In the new process, sea-water is circulated in the concentration compartments in an open circuit without re-cycling; the sea-water serves to assure the rinsing of the electrodes which create the electric field in the cell. In this way the conc. of certain harmful ions in the conc. circuit is avoided and the exchange membranes are not "poisoned"; i.e. their resistance is not increased nor is their selectivity diminished. The membranes are alternately anionic and cationic and the two outside compartments include respectively an anode and a cathode. The even rows of the compartments form the dilution circuit while the odd rows form the conc. circuit. Under the effect of the electric field the cations and the anions of the dilution circuit are extracted through the respective cationic and anionic membranes and pass into the adjacent conc. compartments.
