Title: Composite SiC/Si3N4 coatings or carbon-carbon composite materials
Inventor: VELTRI RICHARD DANIEL
IPC: C04B41/52
Filed: 1984-07-05
Abstract: A composite carbon-carbon article adapted for resisting a degradation due to the surrounding medium at elevated temperatures. This article comprises a carbon-carbon composite substrate to which a coating has been applied, comprising an inner layer of SiC produced by a conversion process where Si is diffused into the carbon substrate, and an outer layer of Si3N4 applied by chemical vapour deposition. Such a coating provides an exceptional resistance to oxidation at 1371 DEG C and above, in the case of carbon-carbon materials. Optionally, preliminary SiC coatings applied by the chemical vapour deposition process or of pyrolytic graphite can be applied before the application of the inner SiC layer. The invention applies particularly for the manufacture of articles employed in the aerospace industry.

Title: Rule for aerial and maritime navigation
IPC: G01C21/20
Filed: 1986-06-18
Abstract: The invention relates to instruments of the navigation rule type which make it possible to plot one's position and find one's route. It involves a protractor equipped such that it can be imparted with two movements, a rotation about its centre and a displacement parallel to its lubber line (0 DEG -180 DEG ). The rotation is performed about a compass point at the centre of the protractor, which point is fitted with a return means (spring). The roller bearing system consists of an axle fitted with rollers locked on this axle and having an identical adherence power on the surface of displacement. The advantage of the invention resides in the fact that the reading of the graduations and the handling of the protractor are simpler and faster than with the conventional system, the two rotational and translational movements no longer being performed by successive approximations, but in two phases.

Title: System for assembling elements of circular ducts using an expansion sleeve
IPC: F16L21/02
Filed: 1986-08-06
Abstract: The invention relates to a system making it possible to assemble, inter alia, elements of circular air ducts without having to resort to drilling and pop-rivet assembly. The sleeve consists of a metal tape 1 having an overlap 6 at one end. A clamping nut 9 which is screwed as required into the tapped hole 11 of the pin 5 exerts a constant pressure on the pin 4 as soon as the bored end of the screw 9 penetrates the blind hole 10 of the pin 4 involved. This pressure expands the sleeve so that the ducts to be assembled 2 previously fitted inside each other, are securely and perfectly assembled. The system according to the invention is particularly intended for assembling networks of ducts clipped together in spirals.
