Abstract: A device for lubricating a power gearbox having a variable orientation and a closed space has a lubricating unit that supplies lubricant to at least one element of the gearbox, which needs to be lubricated. A collecting reservoir collects lubricant from the closed space. A drain screw chamber, within the closed space, has a number of orifices disposed between different zones of the closed space and the drain screw chamber for passing lubricant there between. At least one rotary drain screw, which is produced in the form of an Archimedean screw, is disposed in the drain screw chamber to convey the lubricant from the drain screw chamber to the collecting reservoir. A drive unit drives the drain screw in rotation for conveying the lubricant. The orifices open respectively different zones of the closed space to the drain screw chamber such that the drain screw chamber can always collect lubricant from the different zones regardless of the orientation of the gearbox.

Abstract: Device for lubricating a power gearbox which has variable orientation, particularly for a convertible tilt-rotor aircraft.

Abstract: The present invention relates to a device for elastic connection between two components in order to transmit the static forces from one to the other in the axis of the device and to filter the associated vibratory excitations, comprising an elastic return mechanism (4) connected to a first and a second component and at least one swinging mass (5) located at one end of a lever arm, the lever arm articulated, in the vicinity of its other end, on the first and second components. The lever arm (6) consists of at least two portions (7, 8) articulated on one another, the first portion (7) being articulated on the first (2) and second (3) components in the vicinity of its end (7a) opposite that (7b) articulated on the second portion (8), and the second portion (8) being articulated, in the vicinity of its end (8a) articulated on the first portion (7), on the second component (3) and carrying the mass (5) at its opposite end (8 b).

Abstract: Aromas, carbon dioxide and water obtained from roasted coffee are condensed into a frost. An oil is mixed with the frost and subjected to sublimate the carbon dioxide from the oil and frost mixture, and then the mixture is melted to obtain an oil phase and an aqueous phase. The oil phase is separated from the aqueous phase, and the aqueous phase is contacted with an oil to transfer aromas to the oil which then is incorporated into a soluble coffee powder.

Abstract: In the decaffeination of green coffee beans with an aqueous medium, caffeine is removed from the aqueous medium which also contain non-caffeine green coffee solids, contact with substantially neutral active carbon. Thereafter the medium may be recycled to extract further amounts of caffeine from the same or another batch of green coffee beans.Other features of the invention are described in the specification.

Abstract: A process for the recovery of xanthine stimulants from an aqueous solution containing xanthine stimulants extracted from cocoa material, which comprises contacting the solution with a substantially neutral adsorbent and separating the adsorbent, with the xanthine stimulants adsorbed thereon, from the aqueous solution having a reduced content of xanthine stimulants.

Abstract: A process for the recovery of theobromine from an aqueous solution containing theobromine extracted from cocoa material, which comprises contacting the solution with a substantially neutral adsorbent and separating the adsorbent, with theobromine adsorbed thereon, from the aqueous solution of reduced theobromine content.

Abstract: A process for forming a vegetable extract in a system comprising a series of cells containing coffee and coffee substitute, by contacting progressively fresher vegetable materials countercurrently with an extraction liquid which enters an inlet cell and is withdrawn in batches from an outlet cell characterized in that the outlet cell and each succeeding alternate cell contains more coffee than any one of their respective adjacent cells and during or after each draw-off the pair of cells containing the most exhausted vegetable material is disconnected from the system for discharge and reloading, and after each draw-off a pair of cells with fresh loads of coffee and coffee substitute is added to the system so that the outlet cell is the second in series and contains the majority of coffee of the pair, the amount of soluble solids in each draw-off being approximately twice the amount drawn off in a standard process.
