Title: Mutual reciprocation of pipe extrusion and draw=off units - to produce thick wall socket zones at optimum constant extrusion and draw=off rates
Inventor: LAGABE ANDRE EMILE RENE
IPC: B29C48/09
Filed: 1976-07-30
Abstract: Extrusion of thermoplastic pipe with periodic variations in wall thickness produced by running an extruder and a separate drawn off machine eash at constant throughput rates and varying the distance between the two units to modify the effective draw-off rate from the extruder, and hence the profile wall thickness. Either the extruder or draw-off unit is stationary and the other is mounted on a power driven carriage capable of converging the two units relatively rapidly resulting in thick wall section extrusion during convergence, and parting the units slowly to produce greater lengths of thin-walled profiles. Used for producing thick-walled zones in pipe at intervals suitable for radial dilation to produce socket mouths which match the pipe walls for thickness at suitable pipe length intervals. The extruder operates under stable conditions and the draw off unit can operate at an optimum speed for grip on the profile surface, providing better dimensional and structural reproducibility than systems which vary extrusion or draw-off rates.

Title: Aircraft radio navigation system - uses Fresnel and Fourier correlations performed on sum and difference signals derived from two ground beacons
Inventor: DOREY JACQUES
IPC: G01S11/10
Filed: 1976-08-19
Abstract: The aircraft mounted radio navigation system simultaneously determines an angular positioning factor and the distance of aircraft from two ground beacons. These beacons each having a rectlinear moving source which at each instant in time move oppositely to each other. The beacons are fed by electromagnetic waves of neighbouring radio frequency. The system uses multiplication followed by filtering to produce beat frequencies which are less than the signals received from each of the beacons. These beat frequencies are multiplied together. They are then filtered so as to obtain on one channel the difference of the beat frequencies and on the other channel the sum of these frequencies. A Fourier correlation is performed on the difference channel and a Fresnel correlation is performed on the sum channel.

Patent FR-2339792-A1 (FR)
IPC: F16J15/34
Filed: 1976-09-20
Abstract: In the seal housing (7) of the sealing device, a sliding ring (16) is held such that it cannot rotate and is supported in the axial direction by springs (20). A counter-ring (24) which rotates with the shaft (1) and is supported axially thereon slides on a radial sliding surface of said ring (16). The sliding ring (16) is sealed by a first secondary seal (21) with respect to a sealing surface (14) of the seal housing (7) with the diameter (d1), and the counter-ring (24) is sealed by a second secondary seal (36) with respect to a sealing surface, fixed on the shaft (1), with the diameter (d2). The diameters (d1 and d2) are the same. As a result, the forces exerted by the pressure of the medium, to be sealed, onto the assembly of sliding ring (16) and counter-ring (24) in the axial direction cancel each other out, so that neither of the rings (16, 24) needs to be supported to the conventional extent and, with changes in the operating state, any deformation occurring in the region of the sealing gap between sliding ring (16) and counter-ring (24) is slight.

Title: Heat exchanger employing flexible hoses - with metallic supports providing thermal contact and mechanical support
IPC: F24S10/75
Filed: 1976-11-05
Abstract: In a heat exchanger composed of materials having very different physical properties, one of the fluids flows through a highly elastic, very thin-walled hose made of a material having rubber-like properties. The hose is enclosed by flat metallic parts having a high thermal conductivity and provided with ribs or fins to provide a heat transfer path between the two fluids in the heat exchanger. The metallic parts also restrain the hose w.r.t. the press. of the fluid inside it, which is deliberately maintained at a value higher than that of the other fluide or of the atmosphere. This results in close contact between the hose and the metal to ensure, together with the thin wall of the hose, a high overall thermal conductivity without mixing of the fluids. Used e.g. for solar heating or as room heating panels.
