Patent FR-2225324-A1 (FR)
Title: Flexible cover for joints between railway vehicles - metal inserts embedded in rubber sheet
IPC: B61D17/20
Filed: 1973-07-23
Abstract: The covers are for the footway joints as well as of the concertina passage way assembly between adjoining railway coaches, particularly articulated ones. These items are subject to much shock and movement and wear, so that rubber alone is not very satisfactory, hence metal insertions are vulcanised in a rubber sheet. These are in the longitudinal direction and can be wires or sheets of spring steel. This remains rigid longitudinally but flexible transversely. The metallic insertions can be in one or more planes. The transverse flexibility allows rapid deformation of shape and return to the original shape.

Title: Direct smelt synthesis of inorganic cpds - esp binary, ternary and quaternary cpds for electronic use, requiring accurate proportioning
IPC: C30B33/00
Filed: 1973-12-14
Abstract: A method of hot-treating an inorganic matl. constituted of >=2 constituents, one of which is volatile at the treatment temp., consists of maintaining an inert gas pressure above the heated matl. A zone of total reflux is formed above the heated matl., the vapour of the liq. constituent being condensed in this zone; the inert gas pressure is adjusted to be substantially equal to the vapour pressure of this liq. constituent, so as to constitute a reflux boundary. Typical applications are direct smelt synthesis of cpds. having special electronic props., e.g. gallium arsenide or HgCdTe.

Title: Supersonic aircraft engine - is conical with central inlet, heat shield and outlet over fuselage
IPC: B64C23/02
Filed: 1974-04-05
Abstract: The jet engine is mounted in the nose of the fuselage. The engine has a conical envelope with the compressor and turbine blades projecting radially inwards from the inner surface of the cone. Air enters the nose of the cone and after passing through the engine it emerges through an annulus and passes over a heat shield and is then ejected over the skin of the fuselage and wings of the aircraft. According to the invention this flow of air reduces the aerodynamic resistance of the aircraft and in addition it prevents the formation of supersonic shock waves which normally give rise to the supersonic bang.

Patent FR-2289227-A1 (FR)
Title: Combustion and purification circuit - has pumps circulating water through purification chamber and filter for gases
IPC: B01D47/00
Filed: 1974-10-31
Abstract: The circuit cleans exhaust gases from combustion equipment before discharge to atmosphere, these gases passing through a filtration and purification unit. The gases pass from the furnace via a pipe to a purification chamber, and pumps and pipes form a water circuit for cleaning the gases in the chamber, in which harmful ingredients of the latter are deposited on the floor and drain into a filter via an outlet spout. The water flows into the sump below and is recirculated through the chamber. Vessels, partly filled alternately with chemical base material and brine, are connected in series by a pipe to the chamber, there being a suction or blower unit between the latter and them. Thus the lighter ingredients of the gases are passed through the materials in the vessels, the last of which is filled with aromatic concentrate. From here the gases are returned to the chimney stack.
Patent FR-2292945-A1 (FR)
Title: Elements for heat exchange between fluids - have extended surface formed by rods passing through holes in perforated plates
Inventor: CARRASSE JEAN
IPC: F28D9/00
Filed: 1974-11-28
Abstract: Elements which go together to form a heat exchanger comprise one or usually two perforated plates through which heat conducting rods or tubes are threaded. The rods protrude either side of te plate surface and are welded to the plate. Where 2 plates make up the element the cavity between the plates is sealed around the plate edges and inlet and outlet orifices are made in the plates. Rods passing through a single plate can be inclined and when the rods pass through 2 plates the ends of the rods extending beyond the outer surfaces of the 2 plates can be inclined towards the bottom. The elements are used for heat exchangers for heat recovery from gas turbine exhausts or for cooling towers of power stations. The type of structure allows plates to be made thinner than in other exchangers so giving a lighter and more economical exchanger. Since rods can be inclined, droplets of condensn. run off them helping the heat transfer coefficient.
Patent FR-2291140-A1 (FR)
Title: Yarn winding device has bobbin driven by grooved roll - guiding yarn and has roll and bobbin movement to prevent yarn build up
IPC: B65H54/74
Filed: 1974-11-12
Abstract: A yarn winding device includes a bobbin supported on a pivoted arm in driving contact with a helically grooved drive roll, yarn being fed into the groove of the drive roll so that the yarn is wound onto the bobbin in the form of a cross-wound package. During winding, one of the ends of the bobbin and drive roll are oscillated in a direction perpendicular to the plane (pref. vertical) contg. the axes of the bobbin and drive roll, and the drive roll is moved so that the yarn is maintained in the groove, If a yarn breakage occurs the action of the yarn on pref. a pivoted lever causes the lever to actuate pref. a micro-switch to brake the drive roller in a controlled manner. At the same time, broken yarn acting a guide pulley operates a cam which moves an arm carrying pref. a pin to bring the pin into contact with a rubber wheel on bobbin to rapidly brake the bobbon. A build of yarn on the bobbin is prevented thereby, preventing breakage. When breakage occurs the device is shut down quickly.

The displacement of the bending tool I is ensured by a hydraulic cylinder fed by the pump. The entire apparatus stands on four feet and may stand on top of a table and the bending process may be accurately controlled.
