Patent FR-2117709-A1 (FR)
Title: Mobile skirt - for converter gas removal installations has a horizontal coolant supply and removal
IPC: C21C5/40
Filed: 1970-12-09
Abstract: The skirt has two circular tubular collectors, one supplying a coolant and the other removing it, situated in two horizontal planes and connected by an array of tubes of smaller dia. than the collectors. The tubes arranged in this way provide a simple circuit for the coolant thus preventing the build up of steam and avoiding overheating. Flow-control diaphragms are unnecessary since the coolant entrance and exit are diametrically opposed and the distance travelled by the coolant is always the same.

Title: Nuclear magnetism well logging - by establishing free precession of chosen nuclei
IPC: G01V3/32
Filed: 1972-05-26
Abstract: A nuclear magnetism well logging tool simultaneously establishes a strong DC magnetic field, to polarise chosen nuclei, and an AC magnetic field in a direction at right-angles to the earth's field and at a frequency corresponding to the Larmor precession frequency of the chosen nuclei. By terminating the DC field adiabatically over a period less than the thermal relaxation time of the chosen nuclei, the latter are swept into driven resonance in the AC field and when that field is then abruptly terminated the nuclei precess freely about the earth's magnetic field and a characteristic of the free precession is monitored.

Title: Thick walled hollow vessel jointing - esp cylinders by layer winding with wire or strip
IPC: B23K9/04
Filed: 1972-09-25
Abstract: The material is wound on a hollow mandrel, whose wall thickness is significantly less than that of the finished vessel, and the turns are tightly butted against each other in each of the layers and against the end cheeks used to strengthen the mandrel. The number of layers used is sufficient for the radial thickness of the winding to be a fraction of the final wall thickness. The machine used is of similar basic design to an electrical coil-winding machine, the mandrel shaft running in bearings in one fixed column at the drive end and in one removable column. Relatively simple method of obtaining adequate stress relief in final joint area esp., of nuclear reactor pressure vessels.

Patent FR-2228189-A1 (FR)
Title: Method of coverring pipes with insulation - uses internal press. to deform insulation between pipe and envelope
IPC: F16L59/02
Filed: 1973-05-04
Abstract: Compressed insulation material is used for the reduction of noise and vibration in pipes induced by fluid flow and also to prevent heat loss. The material (3), solid, elastic or visco elastic is packed into the annular space between the pipe (1) and envelope (2). A requirement for the envelope, either in tubular form or as a wire wrapping is that it must have an elastic limit greater than that of the pipe (1). An internal pressure, p, is applied such that the pipe wall and the envelope are stressed to greater and less than their elastic limits respectively. Whereas the envelope remains elastic the pipe is expanded plastically so that on removing the pressure the envelope contracts to compress the insulation.

Title: Selective hydrocracking of paraffins with mordenite catalyst - deactivated to reduce aromatics degradation
IPC: B01J29/20
Filed: 1973-10-18
Abstract: Light paraffinic hydrocarbons are produced by selective hydrocracking of a hydrocarbon feed contg. n-paraffins, isoparaffins and aromatics in the presence of a catalyst prepd. by (a) treating a small-pore mordenite with an acid, (b) introducing a hydrogenation-active metal or metal cpd. by ion exchange, and (c) selectively deactivating the resulting catalyst w.r.t. hydrogenation of aromatic cpds. The process can be used to produce propane from hydrocarbon feeds contg. linear and/or branched 5-6C paraffins, e.g. straight-run light gasoline, gasoline reformates, vacuum distillate hydrocracking products, etc. The linear and branched paraffins are hydrocracked without significant degradation or hydrogenation of valuable aromatics.

Title: Cornea lens for eye surgery - has concave surface with 8.5 millimeter radius of curvature
IPC: G02B3/02
Filed: 1973-12-19
Abstract: Gonio-lens (1) is in the form of a cylinder truncated by an oblique plane whose base is a concave surface (2). The radius of curvature of this surface ensures a perfect contact with the cornea (13) of the eye, the surface of the oblique section being convex. The radius of curvature of the convex surface is 8.5mm and the angle formed by the planes of the concave and convex surfaces of the lens (1) is within the limits 20 deg. to 60 deg. This allows a beam of laser radiation (9) to be focused on the corner (8) of the rear chamber of the eye for gonio-puncture. The lens ensures low energy losses, precise focussing and prevents destruction of the cornea by the laser radiation.

Title: Upper video spectrum correction cct. - is for SECAM and PAC with magnetic recording systems to replace line drop-outs
Inventor: CANG LUC PHAM VAN
IPC: H04N9/88
Filed: 1974-12-27
Abstract: The upper video spectrum correction circuit, for SECAM and PAL magnetic recording systems, allows dropped-out lines to be replaced with other information and can readily be connected to monochrome or NTSC systems. Correction takes place in two stages. For monochrome or NTSC, the missing part of the video signal is replaced by a preceding line or lines. For SECAM signals, the upper part of the video signal spectrum is replaced for the complete duration of any line. For monochrome, correction takes place by replacing the drop-out line with a preceding line containing the same chromatic information. For PAL systems a variation of the second stage is used.
