Abstract: PCT No. PCT/DE89/00357 Sec. 371 Date Oct. 29, 1990 Sec. 102(e) Date Oct. 29, 1990 PCT Filed May 30, 1989 PCT Pub. No. WO89/12353 PCT Pub. Date Dec. 14, 1989.An FM receiver includes an IF unit followed by an LF unit. The receiver has circuitry for changing the signal transmission characteristic of the IF and/or LF units, including a detector module with detector circuits for detecting values characteristic of receiving or interference states, with the inputs of these detector circuits each being connected with a circuit point of the IF or LF unit carrying the signal to be processed and with the outputs of these detector circuits providing signal characterizing receiving the interference states. The circuitry for changing the signal transmission characteristic also includes an evaluation circuit for processing the signals characteristic of receiving or interference states, the evaluation circuit having an input portion with at least one amplitude and/or time threshold circuit connected with the detector module and having a logic unit which is connected to the input portion and which provides processed signals characteristic of receiving and interference states as control signals to influence individual stages of the IF or LF unit. One of the detector circuits in the detector module determines if the demodulated signal undergoes a voltage leap exceeding a predetermined value, and if so a follow-up voltage for controlling the center frequency of a relatively narrow-banded IF filter is cut off.

Abstract: Un système de propulsion marin (200) doté d'un moteur à combustion interne (212) deux temps comporte un mélangeur (2, 602) d'huile-carburant modifié empêchant un excès d'huile dans le mélange lorsque le carburant vient à épuisement. Le mélangeur modifié comprend une chambre auxiliaire (602) recevant du carburant à partir de la chambre de travail (22) du mélangeur en-dessous d'un niveau donné, une admission de vapeur (606) recevant de la vapeur de carburant ou de l'air provenant de la chambre de travail au-dessus du niveau donné, ainsi qu'une sortie de vapeur (608) évacuant la vapeur. Lorsque le réservoir de carburant (5) est à sec, de l'air est aspiré par un passage de transfert (38) dans le mélangeur à un côté du diaphragme mobile (24), et une aspiration de la pompe à carburant (11) est appliquée aux deux côtés du diaphgrame pour arrêter le mouvement de l'air et stopper le pompage d'huile à partir du réservoir d'huile (7) jusqu'au moteur. L'invention améliore également la précision du rapport du mélange d'huile-carburant en fonctionnement normal.

Filed: 1990-10-18
Abstract: The AC-DC converter (rectifier) in each case has an input switch (21, 22) for the positive and the negative half cycle of the input AC voltage. Capacitors (23 and 25 respectively) for the positive and negative half cycle are in each case connected to the respective input switch. Allocated to the respective capacitor (23, 25) is an output switch (24 and 26 respectively) which connects the capacitors (23 and 25 respectively) alternately to the output of the AC-DC converter. The AC-DC converter according to the invention is very simple and cost-effective to manufacture, and, because of the fact that no transformers are used, it has a very low weight. The converter is particularly suitable for loads which are remotely supplied with AC voltage. <IMAGE>

Abstract: The measuring device comprises a detector (1) for a quantity x to be measured, which detector is adapted to produce two signals I₁ and I₂ which relate to x as x=(I₁-I₂)/(I₁+I₂). 
The device furthermore comprises a processing circuit (3) which includes a first and a second logarithmic converter (9, 11) whose inputs receive input signals V₁ and V₂ which are proportional to the first and the second measuring signal I₁, I₂, respectively.

Abstract: PCT No. PCT/GB90/00522 Sec. 371 Date Oct. 1, 1991 Sec. 102(e) Date Oct. 1, 1991 PCT Filed Apr. 6, 1990 PCT Pub. No. WO90/11967 PCT Pub. Date Oct. 18, 1990.The electronics industry demands that hydrogen peroxide for use therein be purified to very low levels of impurities, currently at the level of a few ppb for some impurities, or even lower. However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level. The instant purification process first makes a concentrated suspension of stannic oxide particles in an aqueous medium, which can include aqueous hydrogen peroxide, by subjecting the mixture to high shear mixing, introducing an effective amount of the dispersion into the peroxide solution and filtering the mixture so as to remove the stannic oxide particles that now are loaded with ionic impurities, and particularly with transition metal ions. Purification to very low impurity levels can accordingly be made with improved safety.
