Title: Welding arrays of elements to form a grille - with one array notched pref. obliquely to the direction of the second array
IPC: E04C2/42
Filed: 1977-05-11
Abstract: An array of parallel wires, rods or profiles having notches or openings cut into them at regular intervals is arranged so that a second array of parallel wires, rods or profiles can sit in the openings so as to form a network or grid of regular opening size. The geometric shapes of each of the overtures and of the wire rods, or profiles engaging the openings are chosen so that the contact between the elements occurs along lines such as edges or generatrices, the lines of contact giving rise to the same wt. of weld beads after passage of an electric current between the two arrays of elements. The elements of the grid or grille are welded together without pressing and with the minimum consumption of energy. No enlarged joint areas are produced as occurred without the cut opening.

Title: Supercharged Diesel engine booster - has high pressurised air stored in bottle and fed to turbine of supercharger at high loads
Inventor: KERVAGORET ALAIN
IPC: F02B29/00
Filed: 1977-07-08
Abstract: The performance of a super-charged diesel engine, when starting or when a sudden increase in load is required, can be improved by supplying it with additional air. The air is stored at high pressure in a bottle connected through a valve to the inlet of the turbine driving the super-charger. A sensing device detects the drop in speed when the load increases. A signal is transmitted to an electronic circuit which opens a valve on the auxiliary air supply. This additional air supply matches the additional fuel being supplied by the fuel pumps and so ensures complete combustion.

Title: Cladding cylindrical objects, esp. pipeline sections with insulation - in continuous process densifying and protecting foamed layer surface
IPC: B29C63/00
Filed: 1977-10-03
Abstract: A foam forming mass of insulating material is applied to a cylindrical object, esp. a continuous run of pipes for transporting petroleum, natural gas, etc., whilst it is moved lengthways relatively to its central axis, on which it is also rotated. A layer of foam forming material is sprayed on first and this, aftr it has been allowed to expand, is wrapped in a strip of flexible sheet material. Sufficient tension is applied through the strip on to the expanded material whilst it is still deformable, to densify the surface zone of the foam. This densifying operation includes the application of sufficient pressure to raise the final density in the surface zone to 10-25% above the density which it would have had, had it been allowed to expand unhindered. The foaming material is applied at a consistently uniform thickness to the pipe and without damage to the cell structure. The insulation is protected against damage by winding on a ribbon or adding an extruded surface coating. Desired zones of the object can be easily marked so that they can be found after covering, damaging the insulation.
