Patent FR-2288601-A1 (FR)
Title: Method of forming coating on roadway - uses binder and aggregate mixed and heated in situ.
Inventor: ROFIDAL SERGE
IPC: E01C7/35
Filed: 1974-07-16
Abstract: The coating for highway surfacings etc., constitutes an aggregate and a binder which are mixed on the carriageway and the coating is heated up to 100 to 200 deg. C at a point 1mm beneath the surface. A highly viscous and adhesive hydrocarbon binder is sprayed on the carriageway surface at between 0.8 and 1.8 kg per square metre. The desired aggregate is now spread onto the surface folowed by compacting and levelling, the above heat treatment then being applied to bond the aggregate to the surface. The hydrocarbon binder is sprayed at a temperature of between 80 and 140 deg.C and is formed by a mixture of bitumen and tar, the latter forming 15 to 30% of the mixture by weight.

The inverter diodes are connected over a semiconductor switch to the setting control circuit light emitting diodes.
Patent FR-2248400-A1 (FR)
Title: Venetial blind winder mechanism spool - traction band actuated ratchet stops spool rotation when blind has been lowered
IPC: E06B9/322
Filed: 1974-10-23
Abstract: The spool attaches to one end of a traction band leading to the lower blind bar and rotate to effect winding and unwinding of this band. A traction band actuated ratchet (15) stops spool rotation once the blind has reached the end of its lowering run, thus preventing immediate blind retraction due to continued spool rotation. The spool (7) incorporates a spring (16) loaded radially movable bar (15) which is normally pressed down flush with the drum surface by the weight of the traction band, Once the blind is lowered and the band has unwound from the drum surface the bar emerges to engage stops (12, 13) and prevent further rotation. The spool (7) is flanked by two further spools (9, 8) contg. blind blade rotation cords.

Title: Fuel economy for power generation - thermal units insered in distribution network store and release energy
IPC: F24D3/00
Filed: 1974-12-13
Abstract: Savings in fuel consumption can be made by building "thermal groups" at selected places in the distribution network. The thermal groups are made up of a heat engine, using any type of fuel, coupled to an electric generator with special arrangements to minimise heat losses. The groups are placed in an insulated sound-proof enclosure. Some of the recovered energy is stored in reservoirs in the form of hot water, the heat being used to meet variable and sudden demands. This system is using groups is applicable to all situations where heating is required. A group may be air cooled, and the air recirculated for heating.
Patent FR-2259285-A1 (FR)
Title: Shaft bearing support with uniform clamp loading - has offset bore or variable depth slots to weaken cover towards clamp
IPC: F16C35/04
Filed: 1974-12-16
Abstract: The support block provides a uniform clamp loading around the circumference of the bearing housing. The support block (1) is split (5) so that the bearing (3) may be inserted easily. After insertion, the clamp holt (6) is tightened to hold the housing in place. In order to provide the uniform loading on the housing, the centre (4) of the bore of the block is offset (e) from the centre line (7) so that the thickness of the cover increases with distance from the slot. Alternatively, internal slots (8) may be cut in the cover, their depths decreasing with distance from the clamp bolt, the main point being to make the flexibility of the cover greater near the clamp bolt. External ribs (9) may also be used.

At the upstream end of the precombustion chamber are inlets directing combustion air along the walls inside towards the outlet, while downstream fuel nozzles form a layer along the walls for vaporisation and mixing with the air. The nozzles are supplied via an annular distribution pipe round the outside of the chamber. A cooling sleeve (48) encloses, in conjunction with the precombustion chamber wall, the distribution pipe (46), and almost entirely surrounds it. This sleeve has an inlet (50) and an outlet (52) for the cooling air which flows along the pipe between them. A thermal screen (39) can be mounted outside the sleeve.

Patent FR-2352245-A1 (FR)
Title: Process and equipment for unwanted product separation - particularly gases from liquefied natural gas, using an automatic pressure control system for removing unwanted material
Inventor: HILY ANDRE MICHEL
IPC: F17C13/00
Filed: 1976-05-19
Abstract: The equipment and process described facilitate the removal from a fluid, in a given phase, of unwanted prods. which are present in a different non-miscible phase, having a different density. The fluid flows along a piping circuit in which a collector is placed. The unwanted prods. are sepd. into the collector where two distinct phases are formed, one being the main fluid and the other the unwanted prods. The unwanted prods. are removed from the collector. Their removal is monitored by manometric pressure, the fluid being allowed to accumulate until a predetermined pressure threshold is reached when the removal of the unwanted prods. begins, continuing until the pressure drops to a second threshold point when it is stopped. Method is partic. suitable for removal of gas from liquefied natural gas, the gaseous phase which tends to form as a result of the inevitable temp. variations. The method does not involve the use of many people.

Title: Floating pipeline support system - has several horizontal floats connected to pipe at ends with release mechanism at one end
Inventor: BARTOLI HUBERT LOUIS ANTOINE
IPC: F16L1/24
Filed: 1976-07-06

Title: Heating and cooling system for building - has primary circuits with reservoirs between heat exchangers of secondary circuits (SW 3.4.78)
IPC: F24D11/00
Filed: 1976-10-01
Abstract: The building has a heating circuit in which water is pumped from a heat exchanger through a condenser to room heaters and back to the heat exchanger. A similar cooling circuit pumps water from another heat exchanger through an evaporator to room cooling units. The condenser and evaporator are linked in a refrigerator circuit and there are bypasses round the room heaters and coolers. The two heat exchangers are served by two primary circuits from a bank of reservoirs. The reservoirs are linked to the two primary circuits by three way valves so the water can be transferred between the heat exchangers and the reservoirs in any desired way.

Patent FR-2338753-A1 (FR)
Title: Long straight sections formed from metal strip - with compensation for edge bow before transverse bending of strip
IPC: B21D11/20
Filed: 1977-01-24
Abstract: A long part is made form flat rolled metal strip, the novelty being that the flat strip is elastically deformed so that its edges acquire the desired form; and the strip is held in its elastically deformed state while at least one of its edges is bent. Prior to bending at least oen of the edges of the string, and while it is elastically deformed, the strip is pref. drilled and/or sheared. The elastic deformation is pref. produced by wedges pushing the sides of the strip, e.g. to straighten the strip. The pref. device for bending at least one edge of the strip consists of a die with a punch provided with a row of tapered centering pegs which fit in the drilled holes in the strip to align the latter before bending. Used e.g. to make parts 12 metres long for the chassis or coachwork of lorries. When long, straight parts are made from rolled strip, the edge bow generally means that strip wider than necessary must be used, thus increasing the scrap. The invention overcomes this problem.
