Patent FR-2758525-A1 (FR)
Title: Helicopter foldable rotor blades
Inventor: BIETENHADER CLAUDE
IPC: B64C27/50
Filed: 1997-01-17
Abstract: The foldable rotor blades are for the main rotor of a helicopter comprising a hub (2), fixed at the end of a rotor mast (1), which is rotated about an axis (zz). Each rotor blade (3) is joined to the hub by a connecting part (5) which is itself connected to the hub by articulations (4). This enables angular clearance of the corresponding blade in pitch relative to the hub around a longitudinal pitch changing axis (CX). Each blade is pivoted relative to the corresponding connecting part around a folding axis (BB) so as to be displaced on stoppage of the rotor, between two positions. One is the flight position, in which the blade extends radially from the connecting part. The other is the folded position in which the blade is pivoted about the folding axis on a side of the connecting part toward the helicopter rear. The folding axis is in a radial plane passing through the rotor axis and is inclined to the rotor axis so as to converge toward the rotor axis from the opposite side of the rotor mast.

Patent FR-2760082-A1 (FR)
Inventor: LETEURTRE PATRICK
IPC: G01B7/00
Filed: 1997-02-27
Abstract: The invention concerns a contactless system, in particular using capacitive means, for measuring pistons of all sizes. This fast and accurate system measures connecting rod borings (diameters of several sections, coaxiality of the axes of connecting rod borings, distances of said axes at the piston head), using a reference cylinder (30) immobile relative to the piston to which are related all the measurements carried out by a double sensor simultaneously measuring the boring and the reference cylinder. The measurements of distances along the direction of the connecting rod boring axes are carried out by the sensor (85) of the double sensor translation (84). The external diameters of the piston skirt and the grooves of the piston rings are measured by the sensors (91, 95, 93, 94, and 22). In a preferred embodiment the system uses 32 capacitive sensors to carry out the complete measurement of a piston in ten seconds only.

Title: Asbestos treatment to produce inert vitreous product
Inventor: TEDJAR FAROUK
IPC: A62D3/40
Filed: 1997-03-11
Abstract: An asbestos treatment process involves chemical transformation of the fibrous structure by adding a fluxing compound (e.g. soda), purification of the resulting solution and thermochemical treatment for converting the fibrous structure into a vitreous structure. Preferably, the chemical treatment is carried out at 80 deg C with a 30% solution of a non-toxic non-polluting flux which does not produce noxious compounds during the chemical or thermochemical treatment. Preferably the chemical treatment preferably involves attrition in an octagonal attrition unit (8) for 45 mins. with a solids/liquid ratio of 0.63, dilution (9), filtration (10) and liquor purification with a sulphur derivative and then lime in two successive reactors (12, 13). The chemical treatment is preferably followed by thermochemical treatment in a crucible-free induction unit and allows chemical conversion at 1400 deg C, which is below the melting point of asbestos alone.
