Abstract: There is provided a method of and apparatus for Automatice Frequency Control (AFC) of pure sine waves (PSW). It is characterized by discriminating to detect frequency differences between a received pure sine wave and a reference frequency (20), integrating (30) the frequency differences to average the differences, and adjusting (40) the reference frequency (80) to eliminate the frequency difference. It is further characterized by digitizing, in quadrature, the received pure sine wave (70), mixing (50) the received pure sine wave with a complex sinusoid to translate the pure sine wave to baseband, quadrature filtering (60) the mixed sine wave, cross-product discrimination (20) to detect frequency differences between a received pure sine wave and a reference frequency, integration (30) the frequency differences to average the differences, selectively (100/110) calculating the mean/variance (90) between the pure sine wave and the reference frequency, and adjusting (40) the reference frequency of a Voltage Controlled Oscillator 80 to eliminate the frequency difference.

Abstract: The invention relates to a method of suppressing amplitude variations of two electrical signals (uS1, uS2) in phase quadrature and a circuit arrangement for carrying out the method. According to the invention, the positive or negative amplitude variation of the signals (uS1, uS2) is monitored for undershooting of a lower or overshooting of an upper reference voltage (+/-US- or +/-US+) in such a way that in the event of undershooting or overshooting a device (20, 22) for changing a prescribed manipulated variable of an actuator (8, 10) is activated, and the signals (uS1, uS2) are respectively converted into rectangular signals (uRS1,uRS2), from which clock pulses (uC11 or uC12) are generated by means of a logic circuit (24 or 26) depending upon the phase sequence of the signals (uS1, uS2) at the positive or negative flanks of the rectangular signals (uRS1, uRS2), which vary the prescribed gain as a function of the result of the amplitude monitoring by a prescribed value (LSB). This yields a method of suppressing amplitude variations of two electrical alternating, periodic signals (uS1, uS2) in phase quadrature with a random phase sequence, and a circuit arrangement for carrying out the method that operates independently of frequency.   <IMAGE>

Abstract: Signalling of articles at the instant of their submersion into water. A sensor, composed of a diaphragm 2 and a piezoelectric cell connected to a circuit for amplifying and handling the signal, is contained in a box 1. 
<??>Elimination of the effects produced by disturbing frequencies is performed by damping these frequencies when transmitting the vibrations of the diaphragm 2 to the plate 4 of the piezoelectric element by interposing an elastomeric bridge 11, whose characteristics are chosen as a function of the desired passband, between the diaphragm and the plate. With the edges of the plate 4 being inserted rigidly into the body of the box 1 and the diaphragm 2 forming one piece with the box, the latter constitutes an acoustic bridge which transmits to all of the parts of the sensor vibrations received from external sources other than water, so that the diaphragm 2 is in static equilibrium and does not transmit any deformation to the piezoelectric element. 
<??>Attenuation or elimination of frequencies not representative of dropping into water.

Abstract: L'utilisation du dispositif d'alimentation en carburant en association avec un système de carburation à rotor assure la présence constante du carburant requis par ce dernier. La bille (21a) et le siège (21b) permettent d'obtenir, à l'état fermé, un degré d'étanchéité qui est pratiquement impossible avec une soupape à tiroir (22). Grâce au déplacement de la bille (21a) et ainsi de la soupape à tiroir (21b), le moteur à combustion interne reçoit la quantité de carburant nécessaire entre le ralenti et la pleine charge. Les dépressions différentes dans la canalisation d'aspiration du moteur, et donc dans la chambre (33), conduisent à des déplacements de la membrane (19) et ainsi de la bille (21a) et de la soupape à tiroir (22). L'électroaimant composé d'une bobine (30), d'un noyau (29) et d'un rotor peuvent, lors du démarrage du moteur à -10 °C jusqu'à -20 °C ou plus, agir sur la membrane (19) et ainsi sur la bille (21a) et la soupape à tiroir (22). Si la quantité de carburant consommée par l'utilisateur (le carburateur à rotor) est faible, une contre-pression est créée sur la membrane (19) de sorte que les écarts diminuent entre la bille (21a), le siège de bille (21b), la soupape à tiroir (22) et le perçage (25). Moins de carburant s'écoule dans la chambre (34), et donc dans le passage d'alimentation (9). A plein régime du moteur, la section du perçage de retour (16) est diminuée et la pression dans la chambre (17) et donc dans le perçage (27) est augmentée, ce qui est justement le but recherché lorsque le moteur fonctionne à plein régime.

Abstract: The invention relates to a hinge for French doors in a refrigerator. The problem involved in a hinge of this type is that the opposite doors without an intermediate support should open with a yielding movement so that the seals of the doors will not rub against each other. The hinge according to the invention makes such a movement possible and is at the same time strong and small-dimensioned, and it makes possible a rapid opening movement and a rapid enhanced closing movement. The hinge comprises a notch (2) and a roller (3) working in conjunction with each other in order to produce a guided lateral movement. The notch is located in the hinge frame (1) and the roller at the upper or lower edge of the door. The hinge additionally has a spring-loaded slide (9) which receives its reciprocating movement from the roller and a slide-guided locking member (11) for locking the hinge in the lateral direction while the door is being pivoted freely.
