Abstract: An extraction chamber with a supply of tablets or small pre-measured quantities of ground coffee by vertical introduction, for an automatic machine for the preparation of hot beverages comprises two portions movable in a horizontal plane. A movable portion or half-chamber is adapted for the inlet of hot water so as to be able to move toward or away from each other to open or close the extraction chamber with a vertical screen and the other movable portion or half-chamber is provided with a vertical filter to receive and evacuate the coffee. The two portions are mounted vertically oscillably toward or away from each other about their transverse axis.

Abstract: A control device for the closing and opening of the extraction chamber (5) of a coffeemaking machine of the espresso type. The extraction chamber (5) comprises two parts (3, 4) movable relative to each other by an electric motor (6) to open or close the extraction chamber (5). The device comprises: elements for measuring the intensity of the supply current of the motor (6) at least during the closing phase of the extraction chamber (5); elements for detecting a drop in the derivative relative to the current supply time below a predetermined threshold, permitting detecting the optimum closed position for the extraction chamber (5), so as to stop the movement of the movable parts (3, 4) when this position is reached.

Abstract: Process and device for selectively removing at least one functionalized organic compound present in a liquid medium, in which a stream of gas is circulated in the liquid medium and the liquid medium is simultaneously subjected to the action of ultrasonic waves.

Abstract: Device for the extraction of coffee, includes an extraction chamber supplied by the vertical introduction of tablets or premeasured small quantities of ground coffee. The extraction chamber includes two movable portions for horizontal movement so as to move toward or away from each other, one of the movable portions including a hot water inlet, the other having a coffee extract outlet. The movable portions are each mounted on an eccentric shaft adapted to transmit to them oscillatory movements of opposite directions. A braked pivotal connection between each eccentric shaft and each movable portion, combines a horizontal movement and an oscillatory movement for sequencing the phases of opening and closing the extraction chamber. The device is useful in coffee machines of the espresso type usable with tablets or premeasured small quantities.

Abstract: A process for color adjustment of a color monitor including a cathode-ray tube and a brightness adjustment module includes providing a nominal brightness signal downstream of a white level adjustment module for adjusting a white level and upstream of a black level adjustment module for adjusting a black level. The process also includes setting a voltage required to obtain a black color image, setting a voltage required to obtain a white color image, providing the nominal brightness signal upstream of the white level adjustment module, and setting the voltage required to obtain the black color image.

Abstract: A preamplifier including an input stage adapted to receiving an analog signal via a connection capacitor, and a differential output stage adapted to providing the signal referenced with respect to a predetermined level, and circuitry for enabling the input stage to accept a signal referenced to the differential stage ground, the signal provided by the output stage being referenced to this ground.

Abstract: The present invention relates to a preamplifier including inputs for receiving input video signals representative of an image to be displayed on a screen, inputs for receiving logic signals representative of information to be displayed in superimposition on the screen, and outputs for supplying output video signals generated based on the input signals or the logic signals. An input receives a control signal to select which signals are used to generate the output video signals. In a first display mode, the signals used are the input signals, and in a second display mode, the signals used are the logic signals. Decoders and controllers allow monitoring of the state of the logic signals which select, in the second display mode, the input video signals to generate the output video signals.

Abstract: Packaging of ground coffee in the form of pastille, "dosette" or predosed bag (1) usable in espresso coffee machines, the pastille, the "dosette" or the predosed bag (1) being formed of filter-paper (3) which encloses the ground coffee (4). The ground coffee content (4) placed in the pastille or the like is partially or totally circumscribed at its periphery, by at least one piece (6) of a sufficiently rigid material acting as a frame, so that the pastille or the like (1) has a good mechanical behaviour. Application to the production of coffees.

Abstract: The automatic machine for the preparation of hot beverage infusions such as coffee being formed by a group formed of a body facing a boiler intended to be brought closer to each other in order to form an infusion chamber. The machine having, between the body and the boiler, at the infusion chamber: reception members intended to receive an individual package containing the product to be infused, the reception members being intended to secure temporarily the package between the body and the boiler; a position fixing element for guiding and maintaining the package in a vertical position when the reception members are present; and an automatic ejection member which ejects the package simply by gravity, the displacement of the package being perpendicular to the axis of the machine.

Abstract: A device for mooring a craft to a docking point (2), including a guide rail (3) vertically attached to the docking point (2), and a prehensile assembly (4) secured to the craft and comprising jaws (6) for gripping the guide rail (3) when in their closed position. An actuator assembly (7) secured to the craft is designed to move the jaws (6) between the closed position and an open position in which the jaws (6) are spaced away from the guide rails (3).
