Title: Electronic commutation system for control of domestic appliance electric motor
Inventor: GUINET MICHEL
IPC: H02P25/08
Filed: 1998-05-15
Abstract: The motor power is controlled by use of magnetisation and free-wheel periods during powering of motor. The procedure for controlling a polyphase electric motor uses electronic commutation of the supply voltage to apply the power to the phase windings during successive periods of magnetisation and demagnetisation.  During each period of magnetisation and demagnetisation a logic signal (PWM) is applied to the phase signal.  For one of the levels of this logic signal, and supply voltage (U) and the inverse of this voltage (-U) are applied to the phase, whilst for the other logic level of this signal a free-wheel regime applies in which a null voltage is applied to the phase windings.  The pattern of the signal is constant throughout the stages of magnetisation / free wheel and demagnetisation / free wheel.

Title: Electric apparatus with supply voltage control, operating in alternating or direct current
Inventor: MEYER OLIVIER
IPC: H01H9/16
Filed: 1999-09-10
Abstract: The invention concerns an electric apparatus, such as a time switch, permanently powered by the mains supply between two terminals A and B and whereof the functioning can be triggered by a control input E brought to the terminal B potential by an external contact SW. The following circuit structure is provided to take into account the possible presence of a light indicator or any other load between the terminals E and A: a low voltage supply circuit AL, operating in mono-alternating rectification, supplies a voltage Vdd to a microcontroller MC. The Vdd terminal is connected to terminal B and the voltage Vdd is regulated on another conductor to a potential considered as a zero volt reference. The control input E of the apparatus is connected to a detection input DT of the microcontroller. The microcontroller scans said input to detect whether the contact SW is open or closed: if it is open, the input DT sees a null voltage or an alternative voltage at the period of the 50 Hz or 60 Hz sector; if it is closed, the input DT sees a voltage close to Vdd, and the microcontroller triggers for example the timing of the time switch. The apparatus also operates if the permanent supply between A and B is in direct current.

IPC: B01F11/00
Filed: 2000-09-25
Abstract: L'invention concerne un récipient (1) comportant un plongeur interne mobile (2) muni d'une ouverture centrale (21) simple, relativement grande. Le récipient est doublé intérieurement d'un sac en plastique souple (3) inséré par l'ouverture (21) pour recevoir le liquide à mélanger. Le plongeur est déplacé de haut en bas sous la surface du liquide pour provoquer, sous le plongeur, un écoulement radial accéléré du liquide (A) vers l'intérieur. Lorsque le liquide atteint une zone de collision centrale, le liquide convergent crée un flux axial (B) libre à travers la zone centrale de l'ouverture (21). On décrit des formes de réalisation dans lesquelles le sac (3) peut rouler et se nicher dans un évidement périphérique ménagé dans le plongeur, et l'écoulement radial se créer par déplacement du fond du récipient relativement à une paroi interne fixe munie d'une ouverture. Le mélange est extrêmement efficace et très économe en énergie par comparaison avec des procédés de mélange consistant à forcer le liquide à passer par un orifice à étranglement.
